Features

1. Features

The OpenCom 510 is a communications system for integrated voice and data communication. The most significant feature of this communications system is its modular structure. The OpenCom 510 is designed for installation in a 19" frame.

The frame itself can be installed in a 19" wall-mounted enclosure or in a 19" floorstanding cabinet.

The system provides a number of slots for the installation of modules. In a fully configured system, the following modules will have been installed (and all slots will be occupied): 2 power supply units,

1 control module, 12 interface cards. By combining different interface cards, it is possible to create configurations suited to the user’s specific communications requirements. If, for example, a user requests DECT-capable U pn

interfaces or additional S

or a/b interfaces, one or more interface cards can be integrated without having to exchange the entire system.

Moreover, OpenCom 510 systems can be cascaded, which allows you to integrate a higher number of modules, or networked in order to meet growing communications requirements.

The OpenCom 510 can be integrated into system environments with structured cabling. All connections to a structured cabling patch panel can be made with standard patch cables.

The OpenCom 510 supports the following communications applications:

■ Telephony with system telephones, ISDN telephones and analogue terminals,

Internet/intranet data communication, CTI applications, sub-system operation and system configuration using a standard web browser

■ Additional software packages for expanded telephony functions can be operated and for making telephone functions more comfortable, e.g. the digital voicebox and voice portal systems OpenVoice and OpenAttendant.

■ The “DoorLine” intercom system can be operated.

Telephony

The OpenCom 510 communications system is designed to be connected to an

ISDN basic access interface using the DSS1 protocol. Both multi-terminal access

(point-to-multipoint) and system access (point-to-point) configurations are sup-

Features ported. The system can be configured to run both types of access in parallel. S

0 and S

interface cards are available for connecting the system to the telecommunications network. An S

interface card provides eight S

ports (switchable to either internal or external connections). The S

interface card provides one ISDN

interface for connecting the OpenCom 510 either to a primary multiplex interface or to a second PBX (ISDN point-to-point connection). For an overview of

interface cards, refer to Modules starting on page 59.

The OpenCom 510 firmware is designed for a maximum of 600 users. For information on system limitations, refer to

Technical Data starting on page 209.

The following can be connected to the OpenCom 510:

■ Euro ISDN terminals

■ System telephones OpenPhone 71, OpenPhone 73, OpenPhone 75

■ System telephones OpenPhone 61, OpenPhone 63, OpenPhone 65

■ RFP 22 base stations

■ DECT handsets (with RFP 22 connected to DECT-capable U pn

port of

MS+UPN2-8 interface card)

■ analogue terminals

interfaces must be operated with Euro ISDN terminals in accordance with the

DSS1 protocol.

U pn

ports are suitable for connecting the OpenPhone range of system telephones.

Furthermore, the DECT-capable U pn

ports of the MS+UPN2-8 interface card can be used to connect RFP 22 base stations.

Analogue ports are suitable for connecting standard analogue terminals.

If your network provider supports the CNIP (Calling Name Identification Presentation) feature, the names of callers will be displayed in addition to the numbers whenever external calls are received. The OpenCom 510 supports the display of the name on system telephones. However, if you have created an entry in the telephone book under the number of the caller, this entry will be displayed instead.

Features

The OpenCom 510 can be integrated into an existing local area network (LAN) and used as an Internet access router and mail client by all workstations in the LAN.

The OpenCom 510 can be configured and programmed by means of a web browser (web console). This browser needs to be installed on a PC which is connected to the system.

The OpenCom 510 can be pre-configured at the service centre and remote-configured for service purposes.

A COM port can be used to connect a PC for the purpose of transferring connection data.

You can use the “DoorLine” intercom system to connect the OpenCom 510 to a building’s wiring system, which enables you to use door opener and doorbell functions through the OpenCom 510.

The OpenCom 510 enables you to use third-party CTI (Computer Telephony Integration) applications. This requires the installation of a TAPI driver (provided on the system CD) on a Windows PC. The OpenCom 510 also features the integrated browser-based CTI application OpenCTI 50. Via the OpenCTI 50 users can call up and use telephone functions through their PCs without having to install a special

TAPI driver.

Further Telephony Features

The OpenCom 510 can be used to run digital voicebox and voice portal systems.

The configuration data and the recorded speech files (messages for, or left by, a caller) are stored on the OpenCom 510 CompactFlash card, which is installed on the MC+1-3 central control module.

For further information, refer to the “OpenVoice” and “OpenAttendant” user guides.

You can optimise telephone communication with the help of team functions and the call-queuing function.

The “OpenCount” application, which requires a separate licence, can be used to record and save connection data; these data can be analysed using a number of individually configurable filter criteria. For further information, refer to the web console online help.

Features

You can connect two OpenCom 510 systems (PBX cascading). Cascading is a simple way of increasing the number of terminals that can be connected.

As your communication requirements grow, the OpenCom 510 can be networked with other telecommunications systems. The OpenCom 510 can then operate as a sub-system or as a DECT server. It is also possible to create a telecommunications system with several networked PBXs.

Internet Access

For the purpose of providing Internet access, PCs can be connected to the

OpenCom 510 by means of the internal S

ports, and an entire LAN can be connected by means of the Ethernet port. If Internet access is already available from an Internet service provider, the OpenCom 510 can be configured accordingly. The

OpenCom 510 can also be used for IP configuration if there is no IP-capable client network. An integrated DHCP server and a DNS server will take over IP address administration and name resolution for the client PCs.

The OpenCom 510 enables all connected PCs to access the Internet using a common IP address; only the common address will be visible outside the LAN.

Network address translation (NAT) is used to change the IP addresses of the local

(client) PCs into the IP address of the OpenCom 510. This prevents direct access to the LAN’s client PCs and thus offers protection against attacks from the Internet.

The OpenCom 510 offers further protection of the LAN in the form of customisable filter lists (firewall function).

Note: Also observe the notes in

Useful Information on Internet Access starting on page 102.

DECT Data Communication

PCs that are not connected to the OpenCom 510 via the internal S

ports or the

Ethernet interface can access the Internet if used in combination with the

OpenPhone 27 DECT terminals. PCs in these configurations can also make full use of the Internet and e-mail features of the OpenCom 510.

Data will then be transmitted via the internal data interface of the OpenPhone 27.

The OpenPhone 27 must be connected to the serial port of the PC. The Internet can be accessed directly via the remote data transfer (i.e. dial-up) network. The

OpenPhone 27 will establish a data connection with the OpenCom 510 via the

DECT air interface. The Internet connection itself will be established either directly through an ISDN B-channel or indirectly through the internal RAS interface of the

OpenCom 510. Indirect RAS access is preferable as it uses the routing function of

Features the OpenCom 510 and thus benefits from the security features of shared Internet access.

For detailed information on installing the required driver software and on the various configuration options, refer to the “OpenPhone 27” user guide. For information on configuring the OpenPhone 27 data interface, please refer to the

OpenCom 510 online help.

E-Mail

The OpenCom 510 offers an integrated e-mail function that supports the POP3,

APOP or IMAP4 protocols used to query an Internet service provider for incoming mail. The OpenCom 510 can be configured to enable every member of staff to query mail accounts. The OpenCom 510 fetches the incoming e-mail headers (subjects) and senders from the mail server at set intervals and forwards them to the user’s system terminal.

E-mail accounts for the sending e-mail can also can be configured for users. Emails can then, for example, be sent directly from the OpenCTI 50 to other users.

In addition, users who have had a voicebox configured for themselves, can let themselves be notified of new voicebox messages via e-mail.

Important events and errors are kept by the OpenCom 510 in an internal log book: the error store. To inform or alert the system administrators, entries in the log book

(system messages) can be sent via e-mail.

Voice over IP (VoIP)

The OpenCom 510 supports the connection of VoIP terminals and thereby allow telephony via the existing company network infrastructure. For this purpose, corded system terminals of the type “OpenPhone IP” are available. These devices have the same functionality and support the same features as the non-IP enabled system terminals “OpenPhone”. For users who wish to use PC supported telephony, the IP system terminals are also available as separate licensable software variations (OpenSoftphone). You will find further information in the chapter

Voice over IP (VoIP) starting on page 105).

DECToverIP

DECT networking via VoIP is another possible option for offices already extensively using VoIP telephony. The Radio Fixed Parts (RFPs) are connected via network data connections, so they do not occupy any U pn ports and can use existing network connections. With DECToverIP, VoIP protocol data is changed into DECT-compatible voice data direct on the RFPs. DECT-RFPs and DECToverIP-RFP can be used

Features together in combination in many cases; it is however not possible to switch between RFPs using different technologies during a call.

Further Network Features

You can enable staff to dial into the LAN by means of RAS access.

In addition, you can configure a LAN-to-LAN link via ISDN. Two OpenCom 510 systems can thus connect their LANs for on-demand dial-in (from both sides).

A NET CAPI (driver software provided on the system CD-ROM) enables PCs without

ISDN cards to use ISDN functions.

Factory Settings Telephony Functions

2. Factory Settings

The OpenCom 510 is delivered with the following basic settings and activated features. We recommend that you configure the OpenCom 510 to meet your specific

requirements before putting it into operation (see Configuration starting on page 82).

■ The system PIN, which is used for remote-programmable call forwarding, for example, is “0000”.

2.2

Authorisations

Authorisations determine which functions can be used at the terminals connected to the OpenCom 510. Authorisations are configured for so-called user groups; users and their terminals are allocated to these groups.

Three user groups are preset: “Administrators”, “Standard” and “Guests”. “Administrators” have access to all functions of the OpenCom 510 and unrestricted configuration rights. Users in the “Guests” group cannot configure the OpenCom 510, are not able to make external calls, and have only restricted use of the terminal functions of the OpenCom 510. The “Standard” user group, because of its default settings, is well suited as a starting point for the creation of user groups for normal users of the system (e.g. the staff members of a company).

Note: When the OpenCom 510 is first put into operation, all connected terminals are in the “Administrators” group until a

Factory Settings Authorisations user logs on to the web console. All terminals are then automatically allocated to the “Guests” group. For further information on configuring user groups and users, refer to the online help chapter “User Manager”.

The OpenCom 510 may be connected only to mains sockets with a protective earth conductor.

Install the OpenCom 510 only near easily accessible, wall-mounted mains sockets.

Always use a dedicated circuit with 10 A protection to supply the 19" frame (1-

12 frame).

If the OpenCom 510 is being powered by two MPS+1-AC power supply units, each of the two units must be plugged into its own mains socket. It is not permissible to use multiway mains strips to connect more than one OpenCom 510 power supply unit or a OpenCom 510 and other devices to the same mains supply together.

The mains cables of the MPS+1-AC power supply units must have ferrite rings fitted. The mains cables are factory-fitted with ferrite rings.

4.1.3 Notes on EMC and Earthing

Please note: MOS modules:

Observe the regulations regarding modules and packaging carrying the MOS trademark!

Use earthing wrist straps connected to the appropriate points on the frame (see C in the illustration

OpenCom 510: 1-12 frame mounting points on page 26).

The mains socket’s protective earth conductor and the telephone earth line must be connected to one reference point for potential equalisation. This is normally the OpenCom 510 housing.

Installation Safety Precautions

Earthing and Potential

For the purpose of potential equalisation, all conductive parts of the

OpenCom 510 must be connected to the protective earth conductor (earth busbar of the building’s wiring system) by means of a solid or stranded wire of at least

2,5 mm

(yellow/green).

ø 2,5 mm 2

OpenCom 510: Earthing arrangement

The metal screens of the subscriber and trunk cables must be connected to the circuit common in the distributor or the patch field. The protective earth conductor of the 230 V mains cables is connected to the circuit common and the telephone earth line.

All metal parts of the communications system are mechanically and thus electrically coupled in order to provide protection through the protective earth conductor and the telephone earth line.

4.1.4 Notes on Installing the OpenCom 510

Do not allow any fluid to enter the OpenCom 510 as this may cause electric shocks or short circuits.

Do not install the OpenCom 510 during a thunderstorm. Do not connect or disconnect any cables during a thunderstorm.

The OpenCom 510 is designed for indoor use only. Route the cables in such a way that they cannot be stepped on or tripped over.

Installation Installation, Ambient Conditions

The OpenCom 510 must be securely screwed into the frame when installation work on the system is interrupted or terminated. Unused slots must be covered with dummy covers (included in the scope of delivery).

4.1.5 Notes on Installing Terminals

Only devices that supply safety extra-low voltage (SELV) may be connected to the

OpenCom 510. Proper use of standard terminals will satisfy this requirement.

The analogue interfaces may only be used to connect terminals that meet the appropriate technical requirements. For details, refer to

a/b Ports starting on page 48.

Use a shielded Ethernet cable (STP cable, Shielded Twisted Pair cable) to connect the OpenCom 510 to a Local Area Network (LAN).

Each of the two groups (1 or 2, or C and D, respectively, in the illustration) requires its own power supply unit. Power for the control module is always supplied by the group 1 power supply unit. The group 1 power supply unit must therefore always be installed.

Modules can be installed either when the entire system is configured or as an upgrade at a later time.

4.4.2 Notes on Disconnecting the Mains Supply

DANGER!

Hazardous voltages inside the device!

The OpenCom 510 must be disconnected from the mains supply for the following installation work:

■ Installation of the central control module

■ Installation of a power supply unit

If a 1-12 frame is being powered by two power supply units, it is de-energised by unplugging both mains cables.

Installation Installing Modules

DANGER!

Always unplug the mains cables of both power supply units when installing the central control module or a power supply unit.

If you unplug the mains cable of the group 2 (B) power supply unit, the

OpenCom 510 will still be operational! However, only the modules supplied by the group 1 (A) power supply unit, i.e. the central control module and the interface cards in slots 1 - 6, will be functional.

If you unplug the mains cable of the group 1 (A) power supply unit, the

OpenCom 510 ceases to be operational. However, slots 7 - 12 (D) will still be supplied with operating voltage. (Refer to the illustration

OpenCom 510: 1-12 frame slots on page 27 to determine the location of the modules specified in parentheses

above.)

The LEDs of each module indicate whether the respective module is operational.

For further information on LED indicators, refer to

11.

You can determine the new PARK in the System Info: Versions menu in the

Configurator .

4.6

Uninterruptible Power Supply

If you are using uninterruptible power supplies (UPS) they must be earthed separately.

The total leakage current must not exceed 3.5 mA per mains socket. Use the leakage current specified by the UPS manufacturer as a reference.

An MPS+1-AC power supply unit has a leakage current of < 0.5 mA.

A 900-watt UPS is entirely sufficient to power the OpenCom 510.

4.7

Power Failure

In the event of a power failure, the system memory will retain all data (program and user data) without any changes.

The internal clock will continue to run for 24 hours. If the power failure lasts longer than 24 hours, the time and date will be reset to the factory setting when power is switched on again, and updated (by means of a signal from the exchange) after the first external outgoing call.

With multi-terminal access configurations, the OpenCom 510 provides an emergency service feature: In the event of a power failure, the S

1 interface will be switched to the S

8 interface, enabling you to make calls through a connected terminal.

The following is required to enable emergency service:

■ An MX+S01-8 interface card must be installed.

Installation Power Failure

■ The power failure circuit of this interface card must be activated. To do so, set

DIP switches S17 to S20 to “ON”. The interface card is delivered with the power failure circuit deactivated (default: off ).

■ Port S

1 must be connected to an NTBA (multi-terminal access) and configured as an external connection.

■ Port S

8 must be configured as an internal connection. An ISDN telephone with emergency service capability must be connected to this port.

Note: Emergency service is not possible with system access configurations.

Speech Design. If you are not using an external MoH device, the OpenCom 510 offers an internal MoH feature: You can change the MoH melody in the SYS Configuration: Components menu of the Configurator . For further information, refer to the online help.

Please note: For external music on hold, use only devices with an input impedance of 600 ohms, floating connection. An incorrect input impedance can cause irreparable damage to the

OpenCom 510!

Voice Mail

If you are using an external voice mail system, it must be capable of handling the number of digits used for internal telephone numbers, e.g. five digits if you have configured five-digit internal numbers. We recommend the following Speech

Design products: Memo 200/300/400 or Memo 200-A/300-A/400-A.

The external voice mail system can be connected to internal a/b ports as well as to internal S

ports. For both port types the voice mail system can activate the notification for system terminals with the code procedures *68 resp. #68 .

Intercom System (for a/b)

The intercom systems “DoorLine T01/02” and “DoorLine T03/04” of the german

Telekom’s division T-Com can be connected via the “DoorLine M06” to any a/b port. The “DoorLine” module provides the actor for the door opener contact.

Observe the following when connecting:

■ The intercom system and the “DoorLine” module should be set to their factory settings.

■ In the PBX Configuration : Ports : a/b : Change menu in the Configurator, select

Doorstation 2-wire under Type . Deactivate the Actuator option, if you want

Interfaces and Connectible Terminals a/b Ports to use the actor port of the OpenCom 510 instead of the “DoorLine” relay. The

“DoorLine” actor can be operated only when the speech channel is open at the same time. The internal actor can be operated at any time.

■ The “DoorLine” intercom system has a number of bell keys to which you can assign different call numbers in the PBX Configuration : Ports : Doorbell menu in the Configurator.

■ You can call the “DoorLine” intercom system by entering the code procedure

*102 .

■ The “DoorLine” intercom system can be connected to any a/b port. However, you can use only one “DoorLine” with the OpenCom 510.

For details on installing and configuring the “DoorLine” intercom system, refer to the product user guide.

The intercom system should be installed by qualified personnel only as sensor/ actor contacts will need to be connected to the “DoorLine” module.

5.4.2 Technical Information

The a/b ports have been implemented as RJ45 sockets. Each of the devices listed above can be connected to the a/b interface by means of a two-wire 1:1 cable.

A two-wire cable connected to an a/b port can be up to 6500 m long, provided it is a 0.6 mm twisted-pair cable, or up to 3000 m if a 0.4 mm twisted-pair cable is used.

The 50 Hz/40 V AC ringing voltage of the eight interfaces is supplied by the interface card.

LAN Port

The LAN port (Ethernet interface) on the MC+1-3 central control module allows the integration of the OpenCom 510 into a company LAN (Local Area Network) with the use of a 10-Mbit hub or switch. In such a configuration, the OpenCom 510 can, for example, act as an IP router for establishing Internet connections.

The Ethernet interface supports transmission rates of 10 Mbits/s and 100 Mbits/s in half duplex or full duplex mode. The transmission rate and mode are selected automatically (Auto Sensing function).

A LAN cable (twisted-pair in accordance with 10BaseT or 100BaseTX) must not be longer than 100 m. Safe operation with 100 Mbits/s requires the use of category 5 cables and sockets. Use a shielded Ethernet cable (STP cable, Shielded Twisted Pair cable).

5.5.1 DSL Port

External DSL modems can be connected via the LAN port. This requires the use of an external switch or hub which connects the output of the DSL modem (NTBBA) to the LAN port of the OpenCom 510. The router will then convert the PPPoE protocol to the TCP/IP protocol of the LAN.

Interfaces and Connectible Terminals COM Port

The DSL modem is connected by means of a crossed twisted-pair cable. Alternatively, you can use a switchable port on the hub, which is usually marked with an

“X”.

8. Configuration

Configuration and programming of the OpenCom 510 is performed by the Configurator , a special software application integrated into the system. The Configurator is operated via the Web console, which can be run on any PC connected to the OpenCom 510.

The OpenCom 510 Web console

Using the Web console, you can:

■ perform the initial configuration of the OpenCom 510,

■ configure users of the OpenCom 510 and authorise them to use certain system services,

■ carry out further system maintenance,

■ use PC-supported telephony functions,

■ read out call charge information,

■ access the OpenCom 510 telephone book.

The Web console has an integrated online help function that offers comprehensive information on configuration and maintenance of the OpenCom 510 (see

Loading the Online Help starting on page 87).

Configuration Brief Guide to Initial Configuration

Note: In order to use all the new system software functions, we recommend that you download the latest software from our Web site at http://www.aastra-detewe.de.

For the initial configuration you can connect the PC to the OpenCom 510 via the

Ethernet port. The TCP/IP network protocol is used to set up a connection via one of these ports. You can then open the Web console of the OpenCom 510 and call up the Configurator from there.

Note: To avoid problems with existing network installations, the OpenCom 510’s DHCP server is designed for static address assignment in its factory settings. The OpenCom 510’s

IP address is always168.99.254 in its factory settings.

8.1

Brief Guide to Initial Configuration

Setting up a first connection is quite simple with a standard Windows PC:

Connect the PC’s network card with one of the OpenCom 510.’s LAN ports Use a cross-wired Ethernet cable to do this.

Before starting with the configuration, make sure you have the following documents at hand:

■ An overview of the ports

■ A list of the terminals to be connected

■ A list of the IPEIs, if you wish to log on DECT terminals in the secure procedure

■ A list of the users to be set up (staff entitled to use the services of the

OpenCom 510) with their names, departments, and the internal call numbers you want to allocate to them

■ For Internet access: the Internet service provider access data.

Data not available for initial configuration can be updated or corrected at a later date.

Note: Use the

Configuration Guide starting on page 192. This

will assist you in making the settings in the correct sequence.

8.2.2 Starting the Web Console

Start your Web browser. Enter the OpenCom 510 IP address in the “Address” box: http://192.168.99.254/.

If the configuration PC gets its IP address automatically from the OpenCom 510 or if the OpenCom 510 is entered as the domain name server, you can also start the Web console by entering the DNS name. The DNS name in the factory setting is host.domain

. You can change this in the Configurator ( NET Configuration: LAN menu).

The OpenCom 510 Web console is started. First set the country in which you are operating the OpenCom 510, and in which language the Web console is to be displayed.

Configuration Configuring the OpenCom 510

OpenCom 510: log-on dialogue box

To commence configuration, you must first log on. For the initial configuration, enter your:

- user name: “Administrator”

- password: for the initial configuration, leave this box blank.

Confirm this by clicking on OK . This puts all connected terminals into the

“Guest” user group with restricted user rights. In this way you prevent international external calls from the terminals, for example, while you are configuring the OpenCom 510 and the users.

OpenCom 510: dialogue box for initial access

Configuration Configuring the OpenCom 510

The software opens a dialogue for initial access. Determine an administrator password and enter it in this dialogue. Also fill in the other input fields.

Click on the Configurator button on the home page.

You will find notes on using the Configurator and in the online help. Click on Help in the menu bar or click on TOC to activate an overview of help topics.

8.2.3 Loading the Online Help

The online help can now be loaded in the Configurator:

Go to the SYS Configuration: Components menu. Select the entry Online

Help and click on Browse .

Look for one of the language-specific ZIP files in the OLH directory of the product CD. Confirm your choice by clicking on Open .

Then click on Load to transfer the online help to the system.

Please note: After completion of the loading operation, the system will take a few minutes to analyse the transferred file.

Note: You can download the latest version of the online help from http://www.aastra-detewe.de/.

8.2.4 Finishing the Configuration

When you have completed all the settings in the Configurator , you must save the configuration (see also

Saving and Loading the Configuration on page 91 ).

Then select the Log-off command in the upper menu bar.

8.2.5 Preconfiguration

Configuration of the OpenCom 510 can be prepared at your Aastra DeTeWe Customer Service Centre or by an authorised DeTeWe dealer. For this purpose, a

OpenCom 510 installed here is programmed with the customer data (e.g. user

Configuration Configuring the OpenCom 510 data, call distribution schemes, cord-bound terminals). This data is stored and then loaded into the OpenCom 510 at the customer’s site by a service technician.

This prepared configuration must be completed at the customer’s site (LAN configuration and DECT terminals).

For configuration of the OpenCom 510 Internet functions, first ask the responsible system administrator for details of the customer’s LAN prerequisites.

8.2.6 Offline Configurator

With the aid of the offline configurator a configuration for the system can be issued and created on a Windows PC. Thereby most of the configuration points are available. Each system type of the product family and firmware version release 7.0 or higher, has its own offline configurator; this is managed with the aid of a starter program. The starter program is included on the product CD. The operating systems Windows 2000 and XP are supported.

You can find further information in the chapter PC Offline Configuration starting on page 181.

8.2.7 Remote Configuration

The OpenCom 510 configuration can also be altered or updated remotely by a customer service centre or authorised dealer. This requires activation of internal RAS access in the OpenCom 510 for the customer service centre/authorised dealer.

Note: If one or more MSNs are entered on the

PBX Configuration : System : Remote service menu page in the Configurator and the Status option is activated, remote configuration access is then activated when a data call from one of the entered MSNs is registered.

The customer service centre/authorised dealer can then log into the

OpenCom 510 as an administrator:

■ User name: “Administrator”

■ Password: [administrator password]

Configuration Configuring the OpenCom 510

Note: If you do not wish to let the customer service centre/ authorised dealer know the administrator password, you can define a temporary password for remote configuration with at least five digits.

Use the following code digit procedure on a standard terminal or a system telephone to activate internal remote maintenance access for the service centre/ authorised dealer:

Remote configuration on (log-on with administrator password)

H * 1 9 * Z (system PIN) #

Remote configuration on (log-on with temporary password)

H * 1 9 * Z (system PIN) * Z (temporary password) #

Remote configuration off

H # 1 9 #

Activation is automatically cancelled 30 minutes after the last configuration activity.

Note: During remote configuration, the OpenCom 510 is blocked for RAS access by any further users.

Please note: The system PIN is preset to “0000” and it is absolutely imperative that the system administrator changes it to prevent undesirable remote maintenance.

Using remote configuration, all OpenCom 510 settings (with the exception of the system PIN) can be edited or updated. New software versions of the OpenCom 510 and the software for the connected system terminals and base stations can also be installed (see the SYS Configuration: Firmware menu in the Configurator ).

For security reasons, settings in the Configurator , Net Configuration should only be edited on site to avoid malfunctions or failures in the customer’s LAN (e.g. due to IP address conflicts). Refer to the chapter entitled

Configuration Examples starting on page 94, where interaction between the OpenCom 510 and a LAN is

explained.

Configuration Configuring the OpenCom 510

Forced logoff of another user by the administrator

The configuration of the system can always only be edited by one user. Working on the configuration in parallel is not possible. This ensures that no configuration conflicts arise.

If the user “Administrator” logs in and another user with administration rights is already logged in, then the administrator can forcibly log the other user off in order to configure. This functionality, for example can be used, when configuring remotely, when a user has forgotten to log out.

In order to forcibly log a user off:

The “Administrator” user logs on with the administration password.

They open the Configurator .

A message shows which user is currently configuring the system.

The administrator clicks on the Take over config rights button.

The other user can make no further modifications of the configuration.

8.2.8 Codes for IP Configuration

The IP configuration of the OpenCom 510 is performed on the Web console in the

Configurator , in the NET Configuration: LAN menu.

In the event that the IP configuration of the OpenCom 510 has to be changed and access via the Web console is not possible, you can also use a code digit procedure to change these basic settings. Entry can be made from an analogue telephone, an

ISDN telephone and from system telephones.

Set IP address

H *182 Z (system PIN) *

Z (www) * Z (xxx) * Z (yyy) * Z (zzz) #

Set NET mask

H *183 Z (system PIN) *

Z (www) * Z (xxx) * Z (yyy) * Z (zzz) #

Configuration Configuring the OpenCom 510

Example

Enter: H*1830000*192*168

*99*254#

If required, initiate a system restart with this procedure:

Trigger Restart

H * 1 8 5 Z (system PIN) #

Use the PIN you entered in the dialogue box for initial access . The factory setting is

“0000”.

8.2.9 Saving and Loading the Configuration

Configurations are saved in a file archive and can be loaded to the OpenCom 510 either locally from a connected configuration PC, or by remote configuration.

The following configuration and customer data can be saved and loaded again:

■ Telephony and network parameters

■ User data

■ Telephone book entries

■ LCR tables

For further information, refer to the online help documentation under the topic

SYS Configuration: Data backup .

8.2.10 Receiving System Messages as E-Mail

Important events and errors are kept by the OpenCom 510 in an internal log book: the error store. To inform or alert the system administrators, entries in the log book

(system messages) can be sent via e-mail.

In order not to notified of every error, the administrator can define corresponding log filters (in the Configurator , the LOG Configuration: LOG Filter menu). These filters define which errors (category, severity, number per time interval) should be notified. The e-mails always include an internal event or error number, as well as an

Configuration Configuring the OpenCom 510 explanation of the message. Further, extra parameters (such as the port number when a trunk line drops out) are also provided.

The mail account for this service ( Account for LOG filter ) is configured in the Configurator , NET Configuration: E-Mail Access .

8.2.11 Loading SW Updates

New versions of the system and terminal software can be loaded to the system.

New software versions of the OpenCom 510 are loaded from the configuration PC, which accesses the Configurator (see the SYS Configuration: Firmware menu).

For information on connecting a configuration PC, see

Brief Guide to Initial Configuration on page 83.

The terminal software is part of the OpenCom 510 software and is automatically loaded into the terminals via the OpenCom 510 if the software version in the terminal is different from the terminal software stored in the OpenCom 510.

For further information, refer to the online help documentation under the item

SYS Configuration: Firmware .

8.2.12 Resetting the System Data

You can restore the factory settings of the OpenCom 510 in the Configurator.

Please note: If this is done, all individual settings and the user data are then lost. For this reason, you should back up your configuration regularly, the best time to do so being after every change. For details, refer to the chapter entitled

Saving and

Loading the Configuration starting on page 91 and to the

Web console online help.

Proceed as follows:

In the Configurator, call up the SYS Configuration : Restart menu.

Click on Restart with Defaults .

Confirm this by pressing “OK” when the query dialogue box opens.

Configuration Configuring the OpenCom 510

8.2.13 Generating Your Own MoH Files

The OpenCom 510 comes with an internal MoH file for Music on Hold. The

OpenCom 510 product CD contains a number of MoH files with different volume levels, which you can load at a later time as necessary.

The file format for non-resident Music on Hold is *.wav. You can also save your own

MoH in a *.wav file and load it into the OpenCom 510.

If you have a Windows operating system, you can use the “Sound Recorder” program to generate your own MoH file. This program is usually located in the

Windows directory called “Multimedia”.

The MoH file must be coded with 8000 Hz, 8 bit mono in accordance with CCITT, A-

Law. This coding is required for the OpenCom 510 and can be set in the “Sound

Recorder” when you save the file under Format (CCITT, A-Law) and Attributes

(8000 Hz, 8 bit mono). The maximum allowable size for a MoH file is 256 KB

(approx. 32 sec. play time). If a larger file is loaded then this will be “truncated” and thereby will also only be played for 32 seconds. The MoH capacity can be subdivided in a maximum of 5 files. These files can be used for different companies or for internal and external calls.

Note: If you don't have the Sound Recorder program or the appropriate codec on your Windows operating system, you should install these components from your Windows CD.

Load your MoH file in the Web console's Configurator , in the SYS Configuration:

Components menu.

Note: When generating your own MoH file, you may incur a fee for the use of non-resident melodies (e.g. a GEMA fee in

Germany or MCPS fee in the UK). The MoH files that come with your OpenCom 510 can be used free of charge.

9. Configuration Examples

9.1

OpenCom 510 in Computer Networks

One of the outstanding features of the OpenCom 510 is the integration of telephony and computer networks. Connect the OpenCom 510 via a computer network (LAN) with suitably configured workstations, and you can use its network features from these workstations. Using a Web browser you can access:

■ the OpenCom 510 Configurator

■ call charge administration

■ the OpenCTI 50, with which telephone functions can be used on a PC

■ the OpenCom 510 central telephone book and your personal telephone book as well as to the company telephone book (if the multi-company variant is activated).

In addition, the OpenCom 510 can be used as an Internet access server. RAS access can also be implemented using the OpenCom 510, which enables the integration of external staff in the LAN.

In this chapter you will find several examples of configurations showing integration of the OpenCom 510 in a LAN. Which example applies to your situation depends on the size and properties of the existing or planned LAN infrastructure.

Note: Several menu entries mentioned in this chapter are available only, if you switch on the Level: Expert in the top level dialogue of the Configurator .

9.2

Introduction to TCP/IP

In a single LAN it is possible to use various protocols for the transmission of data.

The connection between a workstation computer and the OpenCom 510 runs via the IP protocol (also named TCP/IP) used on the Internet. IP can be used together with other protocols (e.g. NetBEUI, AppleTalk or IPX/SPX) on the same network.

Every device participating in data transmission using IP requires a unique IP address. An IP address consists of four groups of digits from 0 to 255, each separated by a full stop. The supplementary protocols DHCP and PPP automatically assign IP addresses to devices. Class C networks normally use IP addresses in which the first three numbers are the same and the last number is uniquely assigned to a specific device in the LAN. On the Internet, unique addresses assigned by a special organisation created for this purpose are used. Within a LAN, you can use addresses which are not unique world-wide:

IP Range

192.168.0.0-

192.168.255.255

Common Netmask

255.255.255.0

172.16.0.0-172.31.255.255

255.240.0.0

10.0.0.0-10.255.255.255

255.0.0.0

Comment

256 smaller networks

1 medium network

1 large network

Configuration Examples OpenCom 510 in a Serverless LAN

IP enables the establishment of connections via one or more intermediate stations. The decision whether to connect directly or indirectly to the partner device depends on the network mask. The network mask for a class C network is

255.255.255.0. If the IP address of the partner device does not fit the network mask, the connection is established via the default gateway. If a device knows several data routes to different intermediate stations, one speaks of a router.

The domain name system (DNS) resolves a plain text DNS name into an IP address.

The DNS is a hierarchically structured database, distributed worldwide. A DNS server can supply information on the names and IP addresses for which it is responsible. For all other information, a DNS server contacts other DNS servers. For the establishment of every connection from the workstation, it is possible to give either an IP address, or a name that a DNS server resolves into an IP address.

Note: For further explanations of technical terms, refer to the Glossary on the CD supplied.

9.3

OpenCom 510 in a Serverless LAN

In a peer-to-peer network, the workstations are connected to one another via network cables. In many networks, the cables run in the form of a star from a central hub or switch. Such networks do not require special servers. This configuration example is also valid for a LAN with a server using a protocol other than IP

(e.g. AppleTalk or IPX/SPX).

The OpenCom 510 in a serverless LAN

In a serverless LAN, the OpenCom 510 takes over the IP configuration of the connected workstations. All IP settings necessary for the workstations are assigned by

Configuration Examples OpenCom 510 in a Serverless LAN the OpenCom 510 via DHCP (dynamic host configuration protocol). In this operating mode, an IP address space reserved for such networks is used:

Default gateway IP address

Install the IP network protocol and a Web browser for every workstation which is to have access to the OpenCom 510 network features.

9.3.1 DNS Name Resolution

In a serverless LAN, the internal DNS name resolution is performed by the

OpenCom 510. If you type the string “host.domain” into your browser, a DNS request is sent to the OpenCom 510 IP address. The OpenCom 510 responds with the correct IP address, so that the Configurator home page can be called up.

In a peer-to-peer network (Windows network), the workstations each have a name which is displayed in the network environment. These NetBIOS names can differ from the DNS names assigned to the workstations by the OpenCom 510. The

OpenCom 510 is not visible in the network environment.

9.3.2 Internet Access

If access to an ISP has been configured on the OpenCom 510, the OpenCom 510 can be operated as an Internet access server without any additional configuration of the workstations. When you want to see a Web page, you simply type the URL

(uniform resource locator; Internet address; “http://...”) in your browser. In a serverless LAN, the OpenCom 510 is configured as a DNS server and default gateway. The workstation therefore sends its Internet connection request to the

OpenCom 510.

In almost all cases, the request will contain a DNS name which is unknown in the internal network. When you type a URL into your browser, the OpenCom 510 receives the request to find the corresponding IP address. If the name is unknown in the LAN, the request is forwarded to an ISP’s external DNS server.

Configuration Examples OpenCom 510 in a LAN with an IP-enabled Server

Note: Workstation PCs automatically add a domain name to

URLs without a dot. You specify this domain name in the

Configurator . For example, if you have configured

“firm.co.uk” as the domain name, an access request for

“www.firm.co.uk” will be interpreted as a local DNS request which does not lead to the establishment of an Internet connection. For this reason, you should choose a name which is not used in the Internet as the domain name (“firm-opencom.co.uk” for example).

9.3.3 RAS Access

You can establish a connection to the OpenCom 510 from an external PC via an

ISDN card.

The necessary IP settings are transmitted by the OpenCom 510 on establishment of the connection. The computer that has dialled in has access to all services in the

LAN that can be used via the IP protocol. The authorisation for RAS access is set up in the Configurator via the User Manager: User Groups menu.

The technical properties of the connection can be configured in the Configurator via the NET Configuration : RAS menu. Further information can be found in the online help of the web console.

In a serverless LAN, Windows uses the NetBIOS protocol for accessing files and printers via the network environment. NetBIOS can use NetBEUI, IPX/SPX or IP as the transport protocol. In the network environment, you can only access files and printers on workstations using IP for NetBIOS.

9.4

OpenCom 510 in a LAN with an IP-enabled

Server

In a LAN with an IP-enabled server, you should coordinate integration of the

OpenCom 510 with the responsible network administrator. You must decide on the IP address space to be used and which network services (DHCP, DNS, RAS,

Internet access) the OpenCom 510 is to handle in the LAN.

The OpenCom 510 in a LAN with an IP-enabled server

In many cases, an IP-enabled server configures the IP settings via DHCP for all workstations. In networks in which the IP settings are made manually, you have to enter the corresponding IP settings in the OpenCom 510 Configurator ( NET Configuration: LAN menu). Additionally you should change the DHCP server to static address assignment (in the NET Configuration : LAN : DHCP Server menu) to enable the OpenCom 510, for example to configure connected VoIP system telephones. In certain cases you have to restrict the DHCP function of the IP-enabled server to ignore the MAC addresses for such terminals.

9.4.1 DNS Name Resolution

In a LAN with an IP-enabled server, the latter is also responsible for DNS name resolution. If you want to start the Configurator by entering a DNS name, you must link this name on the server with the IP address used by the OpenCom 510. For further information, refer to the server documentation.

Note: To access the OpenCom 510 under the same IP address after a restart, you must specify this IP address permanently on a DHCP server. On a DHCP server it is possible to link the MAC address of a network card with a specific IP address. You will find details in the server documentation.

9.4.2 Internet Access

You can also use the OpenCom 510 as an Internet access server in a LAN with an

IP-enabled server. To do this, you must enter the OpenCom 510 IP address on the server as the default gateway. In addition, you must edit the internal DNS server

Configuration Examples OpenCom 510 in a LAN with an IP-enabled Server configuration so that the resolution of external DNS names is forwarded to the

OpenCom 510.

In this example, the Internet connection is established from a workstation via the server, which in turn requests Internet access from the OpenCom 510.

There are two different ways of suitably configuring the internal DNS server. You can enter the OpenCom 510 IP address as a DNS forwarder. If you require access to extended DNS information, you can also configure the DNS server for a recursive

DNS request without the DNS forwarder. For further explanation, refer to the DNS server documentation.

If you additionally want to allow file or printer access in the network, you must set up a suitable user account on the addressed server for network log-in. If you use the same log-in name for the

OpenCom 510 user account and the same password for the network log-in, you have to enter this combination only once when dialling in.

Note: In a larger Windows network with several segments, the lists of computer names visible in the network environment can no longer be established by broadcasts. In this case you use a special WINS server whose address the

OpenCom 510 does not make known to the workstation when dialling in with ISDN. For this reason, you enter the address of a WINS server manually in the network settings of the workstation.

9.5

Branch Link

You can use the OpenCom 510 to interlink two LANs via ISDN.

To do this, you configure two OpenCom 510 systems so that they can dial in to each other.

In order for this to work, the two LANs must be configured for different IP address ranges (subnetworks). For at least one of the OpenCom 510 systems, change the prescribed address range for the LAN.

The OpenCom 510 in a LAN-to-LAN link

In the Configurator , NET Configuration: Branch menu you can configure the dial-in settings. The OpenCom 510 will set up a connection whenever a IP data transfer to the other LAN is requested.

Note that such a connection is only set up when specific requests are made. These can be for FTP file transfers, e-mails or downloading Web pages. Name resolution via broadcasts is not possible. If you wish to use the LAN-to-LAN link to access files and printers in the Windows network, you need an IP-enabled server that administers the name resolution for the Windows network.

As the IP address range, you can select one of the 256 class C subnetworks designed for local LANs. Select a class C sub-network in the range from 192.168.0.0 to 192.168.255.0.

9.6

Useful Information on Internet Access

9.6.1 Costs

The OpenCom 510 uses a router function to access the Internet, which means that it automatically establishes an Internet connection when required and terminates the connection after a certain period of time if no data are being transmitted.

Unfortunately, programs other than those typically intended to access the Internet

(such as your browser or your e-mail software) may send out data packets which cause an Internet connection to be established, even if these programs are not strictly Internet-associated applications.

102

Configuration Examples Useful Information on Internet Access

Examples of such programs are the Microsoft

operating system, various multimedia programs such as Realplayer

and anti-virus applications that may establish an Internet connection for automatic updates (the so-called “phone home function”).

It is therefore highly advisable to limit ISP access by specifying the maximum monthly connection time under Connection time per month in the NET Configuration : WAN : [Provider] menu on the web console.

9.6.2 Using the Web

A Web browser not only enables you to use the OpenCom 510 Configurator from every workstation but also to obtain a wealth of information from the Internet.

Simply enter the desired URL in the address field of the browser. Access from a stand-alone PC via an online service differs from Internet access via the

OpenCom 510 in the following respects:

■ When you request a Web page, dialling in results automatically. There is no display of dialogues with manual confirmation of dialling in or hanging up.

■ Requesting Web pages is not a connection-orientated service. When the Web page has been loaded completely, the TCP/IP connection is cleared. If you do not request further Web pages, the OpenCom 510 automatically releases the connection to the Internet after a certain, specifiable duration.

■ It is possible to call up Web pages simultaneously from several workstations.

■ The OpenCom 510 can block access to certain Web pages by means of filter lists.

9.6.3 E-mail

One of the most important services in the Internet is e-mail. E-mails are buffered in individual e-mail accounts on a mail server. Mail servers are operated by ISPs for example. With the OpenCom 510 you can set up one or more e-mail accounts for every user account configured on the OpenCom 510. These e-mail accounts are then checked at regular intervals.

If there are new e-mails in an e-mail account, and the OpenCom 510 has been configured for this function, the user specified in the OpenCom 510 user account is

103

Configuration Examples Useful Information on Internet Access notified of the new e-mail on his system terminal. OpenPhone 6x/OpenPhone 7x and OpenPhone 2x system terminals can also display information such as the sender or the subject of the e-mail.

9.6.4 NAT

Network address translation (NAT) is activated on accessing the Internet (ISP). You require this feature in order to translate internal IP addresses to valid external IP addresses. This has three important consequences for Internet access:

■ Several workstations can share a single Internet access. You do not require a

LAN access, only a single account with the Internet service provider.

■ The IP addresses used in the LAN are translated into IP addresses valid worldwide. So you require no such addresses for your LAN.

■ Only IP connections triggered from a workstation can be established. Consequently, while you can call up Web pages from a workstation, you cannot install a Web server visible in the Internet on a workstation.

Certain protocols cannot be used when NAT is being used. This affects protocols with the following properties:

■ IP addresses are transported in the useful load, e.g. NetBIOS over IP or SIP.

■ The protocol requires an active, inward-directed connection establishment, e.g. ICQ.

■ The protocol will function without TCP/UDP port numbers, e.g. ICMP or IGMP.

The OpenCom 510 NAT has suitable processes for ensuring the functions of many important protocols affected by these rules. These are the protocols FTP (in

“active” mode), CuSeeMe (“videoconferencing”), IRC (“chat”), ICMP errors

(“traceroute”) and ICMP echo (“ping”).

Depending on the internet telephony protocol (VoIP, SIP) the required NAT extension (“Full Cone NAT”) or RTP-Proxy is activated on the Media Gateway Card.

Protocols which require inward-directed connection establishment can be configured in the Net Configuration : Port Access menu. For further information, refer to the online help of this menu.

Voice over IP (VoIP)

10. Voice over IP (VoIP)

The term “Voice over IP” describes the usage of IP-based data networks for telephony. It is possible to distinguish between two different types of VoIP:

■ Telephony via Internet provides cheaper charge-models for telephone services.

For telephony directly via the Internet, only the cost of data transmission is incurred. Various Gateway providers can provide crossover into the PSTN

(“Public Switched Telephone Network”) for a fee. As well as standardised protocols such as SIP and H.323, proprietary protocols such as the Skype network, are used. Voice and service quality via Internet is often indeterminable, because you are dependent on the communication lines of various service providers. which have been optimised for data communication

■ Telephony via Intranet enables joint usage of existing infrastructure for telephony and for data communication. Integrating the two communication networks into a single communications network can provide considerable savings. The OpenCom 510 gives users all the features of system telephony through its use of an IP-based protocol. Furthermore, the standardised SIP protocol can also be used on the intranet. The control of the data connections used makes it possible to define exactly the voice and service quality.

VoIP telephony over the Internet using the OpenCom 510 provides you with the following options (see also

SIP Telephony starting on page 117):

■ You can use low-cost “SIP trunk lines” with your existing Internet connection

■ You can use the services of a SIP gateway service provider to access the public telephone network (PSTN)

■ Automatic fallback (bundle overflow) to ISDN connections in case of the breakdown or over-occupancy of the SIP connection

VoIP Telephony via intranet with the OpenCom 510 offers the following possibilities:

■ Use of IP-based system telephones and of SIP telephones connected to Cat5 twisted-pair ethernet cables

■ Use of IP-based system telephones and of SIP telephones via VPN, RAS, Branch or WLAN connections

105

Voice over IP (VoIP) Quick start

■ Using voice-data compression with compressing codecs, it is also possible to make multiple IP-based telephone calls simultaneously on a 64 kilobit/s ISDN line

■ Use of PC-supported system telephones (so-called “Softphones”) without extra hardware costs

■

Operation of SIP-capable telephony software (see also SIP Telephony starting on page 117)

■ TC system networking using Q.SIG-IP via VPN connections (see also

PBX Networking starting on page 149)

■ Setting up a DECToverIP network lets you use existing Ethernet cabling to set up a DECT network. The special DECT base stations designed for this purpose,

can be handled using OpenCom 510’s Web interface (see DECToverIP® starting on page 133).

Integrating voice and data communication within the Intranet can provide savings possible and a range of new possibilities. However joint usage of existing network infrastructure may also cause conflicts, with IP address configuration via DHCP for

example (for details see Start Procedure starting on page 125). You should

therefore always plan the use of VoIP in the Intranet together with your network administrator. In order to avoid possible conflicts please also note the information under

Fundamentals starting on page 110.

109

Voice over IP (VoIP) Fundamentals

10.2

Fundamentals

VoIP makes the transmission of voice and telephony signalling via IP (“Internet

Protocol”) possible. After a connection is established, the terminal collects voice data (PCM data), which is then sent to the receiver using an IP packet. PCM data can also be compressed to save bandwidth.

10.2.1 Propagation Delay and Bandwidth

IP-based data networks are generally not able to guarantee a specific minimum bandwidth and defined propagation delay. A synchronised 64 kilobit/s ISDN line guarantees a fixed data rate as long as the connection exists. In an IP-based data network, the data rate and propagation delay can vary. Short-term bottlenecks or retransmission due to errors may be the cause. A data flow interruption of a few seconds is barely noticeable when fetching a Web page, but it can be seriously interfere with a telephone call.

A modern Intranet normally offers enough performance reserves and reliability to make good-quality VoIP telephony possible. Specific components can also be optimised; for example by using a modern switch which evaluates the TOS byte of

IP packets or by replacing unreliable connections.

10.2.2 Latency and Packet Length

For technical reasons, there is always a delay (“latency”) between the recording of voice data via the microphone and playback via the receiver. Voice data is recorded for a short period so that it can be sent in an IP packet. The IP packet also has a signal-propagation delay before the receiver can begin playback. For these reasons, the extra time required for voice-data encoding and decoding may be neglected.

An IP packet consists of protocol data and user data. Sending shorter voice-data packets causes the ratio between the user data and the protocol data to become unfavourable and increases the bandwidth required. Sending longer voice-data packets increases latency.

The length of the voice-data packets must therefore be adjusted to the requirements of the transmission medium. Shorter voice-data packets can be sent if a direct ethernet connection exists. If an 64 kilobit/s ISDN line is to be used for transmission, then longer voice-data packets should be used.

110

Voice over IP (VoIP) Fundamentals

Longer voice data packages are generally used for SIP telephony over the Internet.

The following table provides an overview of the required bandwidth for a telephone connection with various parameter settings. The values apply to halfduplex ethernet; for full-duplex the values can be halved.

Note: To ensure SIP compatibility, the older system telephones OpenPhone 63 IP and OpenPhone 65 IP does not support the G.723 codec any more.

10.2.3 Voice Quality

The achievable voice quality depends on various factors. It is possible to optimise voice-data transmission on an existing network using the available configuration settings. Measuring the network quality may also help.

The following comparison provides a guide to voice quality with specific quality levels:

Quality Levels for Voice Transmission with VoIP

111

Voice over IP (VoIP) Fundamentals

Quality Levels for Voice Transmission with VoIP

> 4

Satisfactory

Limited

Unacceptable

Comparable to

GSM

Defective GSM

No Connection

When a call is set up, the terminals involved negotiate the voice-data compression

(“codec”) that will be used. This is the first factor that determines the achievable quality level:

■ G.711 A-Law (Level 1, uncompressed): The audio data of a PCM channel

(64 kilobit/s) is adopted one-to-one. Every VoIP terminal must support this codec. This codec can not be used with an ISDN data connection.

■ G.729A

(Level 2): Reduction to approximately 8 kilobit/s.

■ G.723.1 6.3

(Level 3): Reduction to 6.3 kilobit/s.

■ G.723.1 5.3

(Level 3): Reduction to 5.3 kilobit/s.

Unfavourable packet length selection may reduce voice quality. The duration of the recording and not the data packet’s byte count is relevant in making this selection:

■ Duration <= 30 ms: optimal transmission

■ Duration 40 - 60 ms: one quality-level depreciation

■ Duration > 60 ms: two quality-levels depreciation

The achievable voice quality also depends on the packet propagation delay and the packet loss between the terminals involved. These parameters can be determined using the “ping” program.

112

10.2.4 Optimisation

If you detect a large fluctuation in the propagation delay during measurement, this may also cause the voice quality to deteriorate. This may indicate a defective or overloaded line caused by bit-error or collision correction resulting from retransmission by the transmission procedure.

An existing star-topology ethernet-network may uses a Hub as the central distributor of ethernet packets. A Hub repeats all ethernet packets received on all connected lines. This can cause substantial collisions and result in a high fluctuation in the propagation delay.

If this is the case, use a modern switch component. Selective forwarding of ethernet packets (“Layer 2 switching”) avoids collisions. Modern switch components also evaluate the TOS byte of IP packets, thereby providing the optimal prerequisites for VoIP telephony.

Note: The OpenCom 510 uses a TOS byte (“Type of Service”) value of 0xB8 for IP packets with VoIP data. This requests

113

Voice over IP (VoIP) Fundamentals

“Minimise Delay” and “Maximise Throughput” for IP packets marked with this value.

10.2.5 Call set-up

Various IP-based protocols are used for system telephony via the Internet protocol

made between an IP telephone and OpenCom 510 for the telephone’s start procedure, registration and signalling.

Call data is directly exchanged between IP telephones using the RTP (“Realtime

Transport Protocol”) protocol.

Channels on a

Media Gateway (MGW) are allocated for making a telephone con-

nection with an ordinary terminal or for dial tones. The MGW converts IP voice data into PCM data streams used with conventional telephony and vice versa. For this, IP voice data are exchanged between the IP telephone and the gateway.

Tip: Switching between voice data channels may cause a slight delay in some circumstances. For example: when accepting a call on an IP telephone, headset users should wait about one second before answering.

10.2.6 Useful services

The type of data compression used for VoIP prevents these types of connections from using certain services. Take these notes into account especially if you want to use connections made via Q.SIG-IP or SIP:

■ ISDN data services can not be used

■ Faxes can only be sent using the uncompressed G.711 codec

■ DTMF dial tones are only received by the other party if the uncompressed

G.711 codec is used

■ Analogue modems can not be used

Tip: Configure the actual usage for the a/b ports, e.g. set them to

Fax or Data (analogue) . Connections from and to these a/b

114

Voice over IP (VoIP) Media Gateway (MGW) ports will then be made using uncompressed or ISDN connections where possible.

10.3

Media Gateway (MGW)

The Media Gateway transforms VoIP voice data into PCM audio data. This function converts voice data between VoIP telephones and all other terminal types.

Without the Media Gateway, VoIP telephones can only exchange call data directly with other VoIP telephones. Media Gateway functionality is also required for producing dial tones and making external phone calls with a VoIP telephone. A Media gateway card makes 8 channels available. One Media gateway channel should be available for a maximum of 3 VoIP terminals.

The Media Gateway also takes over the routing function for external SIP connections, making 8 external SIP connections possible.

Using the OpenCom 510, the Media Gateway is provided using at least one

MG+ETH1-1 interface card.

10.3.1 MG+ETH1-1

Field of Application

The MG+ETH1-1 interface card provides 16 Media Gateway channels for VoIP.

The MG+ETH1-1 interface card can be installed in any of the OpenCom 510’s slots

interface cards can be operated.

Technical Data

■ OpenCom 510 can be connected to the LAN via the ethernet port (10/

100 Mbit/s).

■ The interface card supports: all codecs used by VoIP telephones, silence detection, echo suppression and DTMF tone detection.

■ The interface card can not be used in a slave system.

■ The interface card acquires its software from the system. After the card has been installed it will automatically load the required software.

115

Voice over IP (VoIP) Media Gateway (MGW)

■ No settings need to be made on the interface card.

Pin Assignment

The ethernet port’s pin assignment is designed for a direct connection, via a RJ45 patch cable, to an ethernet Switch. You will need a cross-link cable (“Cross-over

Cable”) for connection to a PC.

Indicators

There are four LEDs on the front of the MG+ETH1-1 interface card.

116

Voice over IP (VoIP) SIP Telephony in the Configurator

in the Web console (see also Installing Interface Cards starting on page 31).

Each MG+ETH1-1 interface card requires its own IP address. This can either be assigned statically or obtained via DHCP.

In the Configurator , open the PBX Configuration: Ports: Slots page.

Click on the slot number in the table row containing the desired interface card.

Enter the desired IP address in the IP address configured field. Enter “0.0.0.0” to obtain an IP address via DHCP.

Confirm with Apply .

The configuration page displays the MG+ETH1-1 interface card’s MAC address. You will need this for the static assignment of an IP address via a DHCP server.

10.4

SIP Telephony

The SIP Internet (Session Initiation Protocol) protocol provides you with a low-cost, standardised option for telephoning via IP-based networks. OpenCom 510 enables you to use external SIP telephone connections (“SIP trunk lines”).Furthermore, internal SIP subscribers, SIP telephones or SIP telephony software are also supported.

10.4.1 External SIP connections

The PBX Configuration : Trunks : Route menu gives you the option of making an

SIP connection on a normal ISDN line in case of bundle overflow, breakdown or over-occupancy. You can also set up your system to route certain types of calls, such as international calls, to an SIP connection.

Note: You will need a Media Gateway card for SIP telephony.

You will also need a fast Internet connection such as DSL for SIP telephony.

You will also usually need the services of a SIP provider. A SIP provider operates a special server (the SIP Registrar) to handle connections. The SIP provider also operates a gateway to the ordinary telephone network which users pay to use and

117

Voice over IP (VoIP) SIP Telephony which enables the SIP provider to provide calls to the telephone network.A SIP connection can also accept incoming calls from the telephone network.

The same voice transmission techniques as those explained in

Fundamentals starting on page 110 are used for SIP telephony. SIP telephony has the following

distinctive features:

■ Subscribers are identified through an e-mail-like “SIP ID” such as

[email protected] or [email protected].

■ SIP transmits dialling numbers always in a single data package (block dialling).

Dialling can therefore be concluded with the hash key # on the system terminal, or the end of the number will be indicated by a time-out. The value for this time-out can be defined for each SIP provider separately.

■ You must log on (“Login”) to the SIP registrar before you can use SIP telephony.

Use the OpenCom 510 to manage important information for the registration

(user name and password) of one or more SIP accounts. It is possible to make several calls simultaneously using a single SIP account.

■ A SIP connection causes constant Internet data traffic, so do not use SIP with

Internet access which is paid for according to the time used.

■ RTP call data is also exchanged directly between terminals for SIP telephony, so different codecs can be used for sending and for receiving. It is also possible to change codecs dynamically during a call. You should use every codec available in the VoIP profile at least once, because this will enable you to establish connections with as many SIP subscribers as possible.

■ Fairly large packet lengths are quite normal on the Internet. They compensate for the longer packet propagation delay.

■ A bidirectional RTP data stream with a dynamically-assigned UDP port number is used to set up calls between subscribers. For this reason, incoming RTP calls often fail to get past the Firewall or NAT configuration of the Internet gateway product used. Do not use OpenCom 510 as an Internet gateway if the product used is to be compatible with SIP telephony. These products provide a “Full

Cone NAT” setting for this application.

■ To enable the use of multiple devices on a single Internet connection, the IP addresses used in a LAN (often 192.168.x.x) are translated to a valid IP address using address translation (NAT - Network Address Translation), but no status

118

Voice over IP (VoIP) SIP Telephony information is available for NAT on an incoming RTP connection.To avoid this problem, the IP address of a workstation computer or telephone visible on the

Internet is determined using a STUN server (STUN: Simple Traversal of UDP over

NAT). You can ask your SIP provider for the STUN server.’s IP address and port number If you don’t need a STUN server, leave the SIP Provider field empty.

■ For direct SIP telephony using OpenCom 510, only SIP IDs consisting of numbers for identifying subscribers registered with the SIP provider specified can be addressed

■ For each SIP account you can create just one bundle. You can specify this bundle in routes as a connection option. You can use a network provider rule to specify the routing of numbers within a specific range to use SIP telephony as a preference (see also

PBX Networking

, under

Configuration starting on page 154).

You can configure SIP connections in the Configurator on the pages

PBX Configuration : SIP trunks : accounts and PBX Configuration : SIP trunks : provider . Enter the technical attributes of a specific SIP provider, such as the IP addresses for the registrar and the STUN server under Provider . Under Accounts enter the information for an existing SIP account, such as the user name, password, assigned call number and the maximum number of simultaneous calls possible.

10.4.2 Internal SIP subscribers

The OpenCom 510 becomes available as the SIP server for internal SIP subscriber telephony switching services. SIP telephones connected via LAN or SIP programmes installed on workstation computers can thus establish connections to all other devices or trunks connected to the OpenCom 510. For operation as a SIP server a

MG+ETH1-1

is required. licence assignment

The number of possible SIP subscribers is determined by the number of licences purchased. In order to provide you with the greatest possible flexibility regarding usage of available licences, licence assignment is dynamic via the “Floating licence”. Using a user/code word combination (“SIP log on”) you can have several

SIP subscribers under the same call number. Only every new SIP log-on occupies a new licence. The technical log-on process of a SIP subscriber with a valid user name and correct code word is always successful. Only when a connection is established is there an attempt made to occupy a licence under the SIP log-on. If

Voice over IP (VoIP) SIP Telephony all licences are occupied currently, the SIP subscriber can only make emergency calls.

Note: If the technical log-on is not successful due to an incorrect user name or incorrect code word, the SIP subscriber cannot establish any connections – no emergency calls either.

When a SIP subscriber logs off, when terminating the programme, for example, the associated licence will become available immediately. A licence is also made available when a SIP subscriber’s regular status query is not conducted. The internal clock for automatic log-out is determined by the Profile assigned under

PBX Configuration : Devices : VoIP Phones . The ( Keepalive ) internal clock setting is located on the PBX Configuration : System : VoIP profile page.

Detailed information on the current licence assignment and on logged-on SIP subscribers is located on the System Info : PBX : SIP phones page. This page is where you can reset licence assignment at any time by clicking on Reset licences .

Technical Notes

The names of settings for the various SIP telephones or SIP programmes are not uniform unfortunately. Please refer to the (Help) on the PBX Configuration :

Devices : VoIP Phones page and the following notes when configuring SIP subscribers:

■ The “REGISTER” SIP message must be sent to the IP address of the

OpenCom 510 using the 5060 destination port. For SIP subscribers, this setting is frequently located under “SIP Server” or “SIP Settings” with the terms

“Domain”, “Server IP” and “Server Port”.

■ The “REGISTER” SIP message must contain a valid user name and the appropriate code word (the User name and Password fields in the Configurator under User Manager : User ). For SIP subscribers, this setting is frequently located under “SIP User Settings” or “SIP Account” with the terms “Authorization User” and “Password”.

■ The “REGISTER” SIP message also contains a SIP-URI in the spelling for e-mail addresses, for example

"Displayname" <sip:[email protected]>

The text portion of the SIP-URI (“Display Name”) is not evaluated at log-on from the OpenCom 510. The series of characters before “@” is the “User Name” or

“SIP Username”. The internal call number of the user must always be used here

(the Ph.No. field in the Configurator under User Manager : User ). The series of

120

Voice over IP (VoIP) SIP Telephony characters after “@” is the “Domain Name” or the “SIP Domain”. The IP address of the OpenCom 510 must always be used here.

■ A STUN server (Simple Traversal of UDP over NAT) or a SIP proxy is not required because internal SIP subscribers on the LAN are directly connected to the

OpenCom 510. Switch these functions off if possible.

■ The “G.711 µ-law” codec (North America, Japan) is not supported. If the SIP telephone offers such a setting, you should switch on the “G.711 A-law” (Europe) instead.

Features

SIP subscribers can establish connections to all other terminals and trunks. The SIP protocol generally works with block dialling. This is why the selected call number is only activated after an internal clock has expired or activated immediately via the hash key (“#”) when dialling. This is why code number procedures without the hash key and code number procedures with a concluding hash key can be used.

An overview of code number procedures that can be used is located in the Configurator on the System Info : Codes page .

Activate “SIP phones”. Please also note the corresponding information in the “OpenCom 100, Operation on Standard Terminals”user guide.

Alongside code number procedures, SIP subscribers can also use a series of functional features realized via the SIP protocol. The OpenCom 510 is the ending for all

SIP connections as opposed to what is usually the case on the Internet. This enables SIP subscribers to use OpenCom 510 features. Direct data exchange is thus not possible between two SIP subscribers. The following table shows the possible features.

Features Notes

10.5

VoIP System Telephones

The following telephones and software packages are available for VoIP system telephony:

■ OpenPhone 73 IP: This is a VoIP-enabled edition of the OpenPhone 73 system telephone. This system telephone can be extended with up to three keypad extensions (KeyExtension 73P).

■ OpenPhone 75 IP: This is a VoIP-enabled edition of the OpenPhone 75 system telephone. This system telephone can be extended with up to three keypad extensions (KeyExtension 73P or KeyExtension 75D).

■ OpenPhone IPC: This VoIP software offers the functionality of a system telephone using Windows 2000/XP executable software (see

OpenPhone IPC starting on page 130). This software also provides local answering machine

functionality and can be integrated into CTI applications.

■ The older VoIP system telephones OpenPhone 63 IP and OpenPhone 65 IP can still be used.

10.5.1 Device Properties

The VoIP-enabled versions of the system telephones OpenPhone 73 IP and

OpenPhone 75 IP offer the same features as the corresponding system telephones. Using VoIP system telephones is therefore not much different from using standard system telephones. The following differences exist:

122

Voice over IP (VoIP) VoIP System Telephones

■ Two RJ45 connector ports are available for ethernet connection. The ports are connected to one another via the telephone’s internal switch. The switch supports 10 Mbit/s or 100 Mbit/s full-duplex with priority given to VoIP data transmission.

LAN Port : Allows the telephone to connected to the LAN. Use a non cross-over

RJ45 patch cable to connect to a Hub or Switch.

PC Port : Allows the telephone to be connected to a workstation computer. Use a non cross-over RJ45 patch cable to connect to the PC’s network port.

■ The VoIP system telephone’s power supply is provided by an extra plug-in power supply. It is also possible to provide a power feed via PoE (“Power over

Ethernet”). PoE requires special devices for power feeds, as well as a completely wired RJ45 connection line.

■ You can also connect a standard headset via RJ45 sockets (DHSG standard) to

VoIP system telephones.

■ VoIP system telephone’s audio signals are generated by the telephone itself.

DTMF dial tones and Music on Hold are produced by the Media Gateway function.

■ A VoIP system telephone can also be operated without a permanent connection to the communications system, for example via an on-demand RAS connection.

■ Signalling data for call control, call data during three-way conferences, connections to conventional terminals and external connections is exchanged between the VoIP system telephone and the communication system. During a call between two VoIP system telephones, call data is exchanged directly between the two VoIP system telephones.

■ During the device’s start procedure, the IP address is configured and the device software is requested via the DHCP and TFTP network protocols.

123

Voice over IP (VoIP) VoIP System Telephones

10.5.2 VoIP System Telephone Configuration

The VoIP system telephones OpenPhone 73 IP and OpenPhone 75 IP obtain the required IP address configuration and operating software via the DHCP, BOOTP and TFTP IP protocols. After the power supply is assured, the device’s internal boot loader is started which controls the further start procedure.

Standard operating procedure is to contact the OpenCom 510’s DHCP server so that the start procedure can be concluded without problems. To register a new

VoIP system telephone, proceed as follows:

Temporarily remove the VoIP system telephone’s ethernet connection. Switch on the VoIP system telephone’s power supply. Note the MAC address shown in the display, for instance “MAC: 00:30:42:00:00:00”. Switch off the power supply.

In the Configurator , open the PBX Configuration: Devices: VoIP Phones page. Click on the New button.

Select the VoIP system telephone’s Type and enter the previously noted MAC address. Assign a Name and Phone No.

Confirm with Apply .

Connect the ethernet connection with the VoIP system telephone’s RJ45 connector. Switch on the power supply. Verify the correct start procedure on the display.

10.5.3 LAN DHCP Server

If the LAN already uses a DHCP server to configure workstation computers, there are various options for correctly responding to VoIP system telephones’ DHCP,

BOOTP and TFTP requests. A comparatively simple approach is described here.

Configure the LAN’s DHCP server to ignore DHCP requests from the VoIP system telephones. With a Linux DHCP server program, you must, for example, include the following lines in the system file “/etc/dhcpd.conf”:

} group { deny booting;

} host 192.168.11.12 { hardware ethernet 00:30:42:00:11:22;

124

Voice over IP (VoIP) VoIP System Telephones

Every DHCP service program has similar options. You may need to reserve a free IP address for each VoIP system telephone. You will find more details in your DHCP service program’s online help or handbook. The MAC address of all

VoIP system telephones always begins with 00:30:42.

Configure a fixed IP address for the OpenCom 510. To do this, call up the Configurator and open the NET Configuration: LAN page. Click on the Change button.

Select from Get addresses from the DHCP server the option no . Enter the current IP address configuration in IP address and Network mask . Confirm with Apply .

Configure the OpenCom 510’s DHCP server to assign IP addresses. To do this, call up the Configurator and open the NET Configuration: LAN: DHCP

Server page. Click on the Change button.

From Status , select the address assignment option. Confirm with Apply . The

DHCP Server page is re-displayed.

Add the configured VoIP system telephones to the list of IP addresses. Click on the New button.

Enter the VoIP system telephone’s IP address and MAC address . Enter the IP address reserved by the DHCP service program. Confirm with Apply .

Restart the OpenCom 510 and all connected VoIP system telephones.

10.5.4 Start Procedure

It may sometimes be useful to understand a VoIP system telephone’s start procedure. Examples:

■ A complex DHCP address assignment prevents the operation of the

OpenCom 510’s DHCP server within the LAN.

■ A VoIP system should be operated with a non-broadcast-capable IP connection. This may be an RAS connection, a VPN connection or another type of routed connection.

125

Voice over IP (VoIP) VoIP System Telephones

An external DHCP server can also control a VoIP system telephone’s start procedure. In this case, system software matching the type of VoIP system telephone must be transferred via TFTP.

The file name determined by the telephone type.

OpenPhone 63 IP

OpenPhone 65 IP

OpenPhone 75 IP /ram/ip_tel/opi7x.cnt

RFP 31/32/33/34/41/42 /ram/ip_tel/ip_rfp.cnt

After the VoIP system telephone has been connected to the mains power supply, the start procedure is as follows:

The boot loader starts and shows the VoIP system telephone’s MAC address in the display. A DHCP request is sent simultaneously via broadcast on the

255.255.255.255 broadcast address.

An IP address, network mask and the default gateway for the start procedure are sent from the DHCP server. Via the “Next server” option, the DHCP server also provides the TFTP server’s IP address and the operations software’s file name. The DHCP server uses the MAC address to select the operations software file which matches the type of device.

The boot loader loads the operations software file from the specified TFTP server. The TFTP server’s IP address and the file’s name are shown in the display.

The loaded operations software is started.

The operations software sends a DHCP request on the broadcast address

255.255.255.255. The VoIP system telephone now receives an IP address, network mask and default gateway for operations from the DHCP server. Using

“Option 43”, which is reserved for this purpose, the DHCP server also provides the IP address of the communication system and port number 8100 for registration.

The VoIP system telephone creates a TCP connection to the supplied IPaddress/port-number combination and sends a registration query. The

126

Voice over IP (VoIP) VoIP System Telephones

OpenCom 510 checks the MAC address sent with the registration and confirms the registration request if the VoIP system telephone is listed in the menu

PBX Configuration: Devices: VoIP Phones . The keep-alive time, port number

(8101) for telephony signalling and the value to use for the TOS byte are also communicated in the registration answer.

The VoIP system telephone creates a second TCP connection using the signalling port number 8101 and sends a registration analogue to the U pn

system telephones.

Extra connections are created using the IP protocol RTP (“Realtime Transport

Protocol”) for call data when a call is created. For calls between two VoIP system telephones, port numbers above 8200 are used. For transmission to a Media

Gateway card, a port in the range 1024 – 1087 is used.

If you wish to operate a VoIP system telephone via a routed IP connection (for example VPN or RAS) it may be necessary to configure an external DHCP server accordingly. Please note the selection of the codec and keep-alive time for RAS connections. This can be done by selecting the default profile RAS in the

PBX Configuration: Devices: VoIP Phones for the VoIP system telephone. The operations software provided via TFTP must match the type of device and communication system. You may also need to configure BOOTP, DHCP and TFTP servers for the VoIP system telephone.

10.5.5 Local Configuration

In addition to automatic configuration via BOOTP/DHCP, it is possible to manually configure an OpenPhone 73 IP or an OpenPhone 75 IP. This can make sense, for example, when you wish to connect a VoIP system telephone at a distant location via router. This local configuration is saved permanently in the non-volatile memory of the VoIP system telephone. To change the local configuration, use an additional programme, the Java-based “IP Phone Configurator”.

Note: Java programmes can be run on all common operating systems. To execute Java-based programmes, you must install a suitable Java runtime environment on your operating system (JRE). This can be downloaded under the following web address: http://www.java.com/.

127

Voice over IP (VoIP) VoIP System Telephones

The “IP Phone Configurator” can be started directly from the Product CD. Start

Windows Explorer. Navigate to the Product CD. Double-click the “Aastra-

DeTeWe\IpPhoneConfigurator.jar” file.

The “IP Phone Configurator” dialogue opens. Select the desired language setting (“English” or “German”)from the drop-down menu.

Enter the network address of the VoIP system telephone. You have two connection types to choose from under Connection to IP Phone :

- Deactivate the IP Phone address option to establish a broadcast connection via “UDP-Broadcast”. You have to select this type of connection if the VoIP system telephone has not yet been assigned an IP address. IP broadcasts cannot be transmitted via router. The VoIP system telephone thus has to be directly connected to your PC via a hub or via a switch.

- Activate the IP Phone address option to establish a point-to-point connection via “UDP-Unicast”. Enter the IP address of the VoIP system telephone

128

Voice over IP (VoIP) VoIP System Telephones into the entry field. You can select this type of connection if the VoIP system telephone has already been assigned an IP address.

Enter the MAC address of the VoIP system telephone. You will find the MAC address on the underside of the device. Click on List configuration . The status bar at the bottom edge of the programme window displays “list OK”.

Change the desired settings under Configuration of the IP Phone . Click on

Reset configuration to activate the standard settings for all entry fields.

Click on the Send configuration command to transfer the currently shown configuration to the VoIP system telephone. The status bar at the bottom edge of the programme window displays “send OK”.

Note: The VoIP system telephone receives the configuration and sends a response. The new configuration is only saved and activated once this has happened. This can result in the

“IP Phone Configurator” not receiving the response of the

VoIP system telephone.

Please note: If you are operating multiple network cards with active IP configuration in your PC, this may mean that the loading of configuration data fails. First you deactivate additional network cards or use a point-to-point connection. Sending configuration data with a broadcast connection functions even without a response from the VoIP system telephone.

You can implement the following settings:

IP parameter locally configured : Select the yes option to activate manual IP address configuration. Select the no option to activate automatic IP address configuration via BOOTP/DHCP.

IP address and Netmask : Enter an available IP address and the network mask to be used by the VoIP system telephone.

TFTP server IP address and TFTP server filename : Enter the IP address and the complete file name for the operating software of the VoIP system telephone (see

table on page 126).

Registration IP address and Registration port : This is where you usually enter the IP address of the OpenCom 510 and the port number 8100.

129

Voice over IP (VoIP) OpenPhone IPC

Default gateway : Click on the Add parameter command to have this optional entry field displayed. Then enter the IP address of the router (“Default Gateway”).

Click on the Delete button to remove the optional parameter.

SYSLOGD : For monitoring purposes, VoIP system telephone messages can be sent to a Syslog server. Activate the yes option and configure the SYSLOGD IP address and SYSLOGD port settings to activate this function.

VLAN : To improve transmission security or to enforce security guidelines, PC data transmission and VoIP data transmission can be separated using this method.

Activate the yes option and enter the desired IP Phone VLAN ID for the VoIP data transmission. Enter a value ranging from 1-4094. Data will always be transmitted without a VLAN tag at the VoIP system telephone’s PC access. If you activate the yes option for PC traffic tagged on LAN interface , PC data will be labelled with the PC VLAN ID at the LAN access. Please note that to change the VLAN settings, the VoIP system telephone has to be restarted.

10.6

OpenPhone IPC

Besides the hardware VoIP system telephones, PC software for VoIP telephony can also be deployed. This software can be used with the operating systems

Windows 98 SE/ME and Windows 2000/XP.

Software VoIP system telephone OpenPhone 75 IPC with one keypad module

As well as VoIP system telephony from workstation computers, the

OpenPhone IPC includes the following features:

130

Voice over IP (VoIP) OpenPhone IPC

■ Usage via Mouse/PC keyboard

■ “Drag & Drop” call number selection

■ Integrated answering machine / recording function

■ Terminal control for the sight-impaired

■ Selectable user interface (“Skins”)

■ Display language modification

The workstation computer requires a full-duplex-enabled sound card as well as a suitable headset for audio recording and playback.

You will not need a licence to install OpenPhone IPC but you will require a licence to operate it with the OpenCom 510. Unit licences, enabling the simultaneous operation of a certain number of OpenPhone IPCs, are available.

The licences are activated in the OpenCom 510’s Configurator in the Menu

SYS Configuration : Licences . The system software includes a licence for a demo version for temporary use (60 days). Please contact your local agent or Aastra

DeTeWe representative if you wish to purchase a permanent licence. Licences can be combined. Each licence can be activated only once.

10.6.1 Installation

Installation is done using a setup program. The OpenPhone IPC can also be installed without a user interface. The program can then be used via a CTI application (Net-TAPI or OpenCTI).

Start the installation program from the OpenPhone IPC product CD and follow the installation assistant’s instructions.

10.6.2 Configuration

Analogue to the VoIP system telephones, the OpenPhone IPC creates multiple IP connections to the OpenCom 510. When you start the program for the first time, the Options dialogue is automatically opened. Here you must configure the following values:

131

Voice over IP (VoIP) OpenPhone IPC

Enter in the VoIP IP Address field the OpenCom 510’s IP address.

Enter six hexadecimal-digits into the Device ID field. This device ID is not a

MAC address, so overlapping with existent MAC addresses is possible. The device ID is configured in the Configurator , on the PBX Configuration:

Devices: VoIP Phones page.

Confirm with OK .

Notes

VoIP system telephony requires an active IP connection to a workstation computer. If a Firewall is installed for your workstation computer, you may need to explicitly allow this connection.

If you log on to the workstation computer using a different user name, you must reconfigure these values.

You can use any arbitrary sequence of digits not already in use in the LAN for the device ID. Select a random device ID to secure telephone usage. The device ID can only be read on the Web console.

The displayed menu texts and parts of the operations software are elements of the

OpenPhone IPC installation, but they can be loaded from the OpenCom 510 via

TFTP. where necessary

DECToverIP

Properties

11. DECToverIP

®

In order to achieve optimal network coverage, a DECT network with several DECT base stations can be operated. A DECT network is comprised of DECT terminals connected with the next respective base station (network cell). For users of a DECT terminal, the handover from DECT base station to base station is completely transparent. Even during a conversation, users are switched from one network cell to the next without any interruption. Administration of DECT terminals is done centrally via the OpenCom 510 Configurator in the PBX Configuration : Devices :

DECT Phones menu.

Note: DECToverIP® is a registered trademark of

Aastra DeTeWe GmbH.

11.1

Properties

11.1.1 DECT base stations

DECT base stations can be connected to the OpenCom 510 via U pn

accesses or via network (TCP/IP). These DECT base stations are available for the type of access selected:

■ RFP 22: Access via U pn

with lines up to 1000 metres in length; integrated antennas; 4 voice channels (8 when using 2 U pn

accesses)

■ RFP 24: like the RFP 22; mounted outside enclosed areas (IP55); external antennas

Note: The newer DECT base stations RFP 22 and RFP 24 can be simultaneously operated with the older DECT base stations, RFP 21 and RFP 23. Fax transmissions (group 3 with

ECM) and SARI (roaming with Secondary Access Rights Identification Broadcasts) can be done using the newer DECT base stations. Data transmission via DECT is not available with the newer DECT base stations.

Note: The DECT base stations RFP 32, RFP 34 and RFP 42 support the DECT encryption function. This feature is however, only available if all the DECT base stations support it.

133

DECToverIP

Properties

■ RFP 32: Access via shielded CAT5 Ethernet cable (STP cable, Shielded Twisted

Pair cable) with up to 100 metres of cable from the last Ethernet switch, integrated antennas; 8 voice channels

■ RFP 34: like the RFP 32; mounted outside enclosed areas (IP55); external antennas

■ RFP 42: Access via shielded CAT5 Ethernet cable (STP cable, Shielded Twisted

Pair cable); offers simultaneous function of a WLAN Access Point conforming with the IEEE 802.11b/g protocol; external antennas; 8 voice channels

Note: When started, the operating software for the DEC-

ToverIP base stations is transmitted via TFTP protocol from the OpenCom 510. The configuration for the start sequence is transmitted by the DHCP server of the OpenCom 510 to a

DECToverIP base station for the start sequence.

If VoIP telephony is already being used, Ethernet cable access makes good sense.

Transmission of telephony signalling and voice data via TCP/IP also offers usage of existing network infrastructure and an increase in range using suitable methods.

VPN connections, for example, can be used for data links to provide service to remote or hard-to-reach locations.

11.1.2 Features

All DECToverIP base stations can be connected to a CAT5 Ethernet cable with a 10/

100 Base T. Power is supplied either via Power-over-LAN (IEEE 802.3af ) or via an additional power supply unit.

Please note: The WLAN function of the RFP 42 is activated when connected to the 100 Base T.

DECT terminals offer all system telephony features. DECT telephones supporting the GAP standard can also be operated. Transparent GAP device handovers are supported. DECT encryption of calls can be deactivated for the RFP 32, RFP 34 and

RFP 42 if desired.

VoIP audio communication between the DECToverIP base station and the

OpenCom 510 is made via the RTP/RTCP protocol. RTP voice data are directly converted into DECT voice data by the base station. The base stations support the

VoIP codecs G.711, (uncompressed) as well as G.729 and G.723 (compressed).

134

DECToverIP

Configuration

11.2

Configuration

One of the DECToverIP base stations that is installed assumes coordination and configuration of the DECToverIP functions (DECToverIP-Manager). Select a base station that has a dependable data link to the OpenCom 510. Go to the PBX Configuration : Devices : DECToverIP page in the Configurator . Click on New , to add a DECToverIP base station. Enter the MAC address of the base station that you have selected to be the DECToverIP-Manager. The MAC address of the base station is located on its type label. Enter an IP address for this base station. Confirm with

Apply . Now click Change , to determine the DECToverIP-Manager. In standard cases, leave the Mode in the “IP address from the system DHCP server” setting.

Select the desired DECToverIP base station with the MAC address (IP address) setting. Confirm with Apply .

If the OpenCom 510’s DHCP server is not configured for static address assignment, you first need to configure the IP address of the DECToverIP-Manager with the help of an additional programme (see

Local IP address configuration starting on page 141). Also change the

Mode setting on the PBX Configuration : Devices :

DECToverIP page to “IP address configured local” and enter there the configured

IP address for the DECToverIP-Manager. All other base stations can be operated using either a fixed IP address or an IP address assigned dynamically via DHCP.

Please refer to the information given in the chapter entitled

LAN DHCP Server starting on page 124.

Note: A base station cannot be operated as a DECToverIP

Manager and a WLAN-Access Point simultaneously.You should therefore use a DECToverIP base station which does not have WLAN function as your DECToverIP Manager.

Create a separate entry for each DECToverIP base station and for the DECToverIP

Manager on the PBX Configuration : Devices : DECToverIP page. You use these entries to determine the VoIP data compression (Profile).

135

DECToverIP

Configuration

Configurator: PBX Configuration: Devices: DECToverIP

User administration and set-up of DECT terminals is done in the Configurator of the OpenCom 510 as well.

The DECToverIP Manager offers a separate web user interface to manage the settings of devices with WLAN functions. Therefore at least one WLAN-RFP has to be configured. If everything is configured correctly, you will see the WLAN Config link. Login as the user “Administrator” with the currently set administrator’s password of the OpenCom 510.

11.2.1 Dual operation

Simultaneous operation of base stations via U pn

access and base stations via Ethernet access is possible with the OpenCom 510. Transparent handovers, for example, are only possible when between DECT base stations using the same access technology. When switching over to a DECT base station using different access technology, a DECT terminal automatically re-establishes a connection

(roaming).

Be sure to keep the PARK ID of your OpenCom 510 in mind. The PARK ID is displayed under System Info : Versions in the Configurator . If the PARK ID starts with

31, there may be an attempt at a handover between DECT base stations using different access technology. In this case, make sure that the signal areas of the DECT base stations using different access technology do not overlap. If the PARK ID starts with a different value (e. g. 30), prevention of unintentional handovers is effective.

136

DECToverIP

Configuration

11.2.2 Synchronisation

Transmissions of all DECT base stations at a single location must be synchronised in order that DECT terminals are able to receive multiple DECT base stations simultaneously. Synchronisation can be conducted via U pn

access. It cannot be conducted via an Ethernet/IP connection. DECToverIP base stations are thus synchronised via wireless connection.

When planning a larger sized DECT network, it is advisable to take the following points into consideration:

■ All DECToverIP base stations at a single location must be able to receive at least one, or even better, two neighbouring base stations. Synchronisation requires less signal strength than a voice connection does.

■ Synchronisation range is increased using multiple base stations. To decrease the probability of a connection breakdown, base stations should not be arranged in chain formation. The signal should be distributed with a network that is as extensive as possible and where each base station is supported by multiple synchronisation partners.

■ To re-synchronise, first wait for all current connections to be terminated.

You can operate a DECT network consisting of several remote locations

(“clusters”). A cluster is a number of DECT base stations that operate synchronously with each other. No handover is possible between DECT base stations from different clusters. You should configure a second cluster for DECT base stations of a second location.

11.2.3 Setting up the WLAN function

The RFP 42 DECToverIP base station provide the additional function of a Wireless

LAN Access Point (WLAN-AP). WLAN refers to data transfer by means of radio waves in accordance with the IEEE 802.11b/g standard. This standard enables a wireless connection to be made to an Ethernet network (LAN) using suitably equipped user terminals. Data transfer via radio waves is very fast. Depending on the conditions of the operating environment, it can reach speeds of up to 54Mbit/ s (gross).

WLAN settings are configured centrally for all Access Points using a separate Web configurator, which can be found at the IP address of the DECToverIP Manager

137

DECToverIP

Configuration

(OMM, OpenMobility Manager). You can reach this address by entering the IP address of the DECToverIP Manager directly into the address bar of your Web

Browser. Alternatively, you can also go to the Configurator , to the page PBX Configuration : Devices : DECToverIP and click on the WLAN Config. button. Log in under the User Name “Administrator” and enter the same password as for the

OpenCom 510.

DECToverIP/OpenMobility Managers Login Page

The WLAN function and the function of the DECToverIP/OpenMobility Manager cannot be used simultaneously on the same DECToverIP base station, so you will always need at least two DECToverIP base stations. The WLAN settings are then made as follows:

Set up the existing DECToverIP base stations in theOpenCom 510’s Configurator . Go to the DECToverIP Manager’s Web Configurator.

On the WLAN Profiles page, configure at least one set of settings (see below under:

Setting up a WLAN profile

). Note down the password you have used

(“Pre-Shared Key”), so that you will be able to use it again later when setting up wireless user terminals or notebooks.

Assign the desired WLAN profile on the Radio Fixed Parts page. Click on spanner symbol ( ) on the left next to the relevant DECToverIP base station.

Under WLAN Settings select the number of the configured WLAN Profile .

Confirm your settings with OK . You can use one profile for multiple DECToverIP base stations.

You can now use the WLAN function of your WLAN-enabled DECToverIP base stations and set up the user terminals as required.

Setting up a WLAN profile

The WLAN function of the RFP 42 DECT base station also includes such rarelyrequired features as networks for large company premises or airports. In this guide we will, for the sake of brevity and clarity, describe only those features required for secure standard operation.

DECToverIP/OpenMobility Manager: WLAN Profiles

Use the following settings for standard operations.

General Settings

■ Select the desired WLAN Profile and activate the Profile Active option.

■ Enter a SSID (Service Set Identifier, wireless network identification) to identify a network. This network identification is transmitted at regular intervals, making it easier to find the networks you’re looking for, using the “View available wireless networks” function in Windows XP, for example.

■ For standard operation you should leave the following settings at their default values: VLAN Tag at 0 (Off ), Beacon Period at 100 ms, DTIM Period at 5, RTS

Threshold at 2347 (Off ), Fragmentation Threshold at 2346 (Off ), Maximum

Tip: If you are using only modern WLAN cards with 802.11g, you can further speed up data transfer by configuring the setting

802.11b/g Mode to “802.11g only”.

■ You can prevent the transmission of wireless network identification (SSID) with the Hidden SSID Mode setting. This will however make network identification difficult and does not generally increase data security, so it is preferable to leave this on the default setting of “Off”.

Security Settings

On no account should you use Open System or Wired Equivalent Privacy (WEP) settings , whether out of convenience or in order to avoid configuration problems, unless of course you want to start up an Internet Cafe!

■ Activate the Wifi Protected Access (WPA) option.

■ Under Type select the “WPA v.1”setting. If you are running the Microsoft

Windows XP operating system from ServicePack2 or higher on your computer, you can use the “WPA v.2” setting.

■ For standard operation select the Pre-Shared Key option. Enter a password in the Value input field and leave it set to Text . Use a password with the following characteristics:

– No words or names that can be found in a dictionary

– At least 8 characters long

You could also use the Generate button to generate a password. Some WLAN configuration software does not convert text into hexadecimal values as a standard procedure. If this is the case, go to the Hex Value setting and select the Generate button.

■ Leave the Cipher Length setting at 256 Bit and the Distribution Interval setting at 120 seconds. You will not usually need the settings for WME or for configuring Multiple SSIDs for standard operation.

Address Filter – but this will not hold up users who know about this function for long.

11.2.4 Configuring for a remote location

If you are using a DECToverIP base station in the same LAN as the OpenCom 510, the IP address configuration and software loading procedure which are run when a DECToverIP base station is started are handled by the OpenCom 510 using the

DHCP and TFTP protocols.

For the DHCP function to be available, the DECToverIP base station must be able to reach the OpenCom 510 via a “Broadcast”. In the case of a remote location this kind of access - via a VPN connection for example - will not be possible. As in the case of an IP system telephone, you will have to acquire the necessary system software for the DECToverIP base station with the help of a TFTP server.

Local IP address configuration

The IP address configuration can be set up as a “local configuration” with the help of an additional program.

Open the product CD and call up the “OpenMobility Configurator” Java program. Open Windows Explorer, go to the “Aastra-DeTeWe” directory and double-click on the OM_Configurator.jar” file.

Note: You need a Java runtime library to be able to run Java programs. If you don’t have one installed, you can install one by starting the “j2re-windows-i586-p.exe” installation program.

PBX Cascading Variants of PBX Cascading

12. PBX Cascading

As requirements grow, the OpenCom 510 can be operated together with other

PBX installations. If you merely need a larger number of connections, it is easy to link a second PBX (PBX Cascading). If you want to operate the OpenCom 510 at several locations with different PBXs, this is possible by PBX Networking (see

page 149).

12.1

Variants of PBX Cascading

You can combine two PBXs in order to increase the number of terminals that can be connected. A master PBX and a slave PBX are connected to one another by means of a cable. The two PBXs essentially function like a single PBX with a higher number of ports. The master PBX controls the slave PBX. The following PBXs from the product family can be used for cascading:

Master system

OpenCom 510

Slave system

OpenCom 510

For the PBX Cascading you will need a licence. The licence agreement provides you with the necessary steps to activate this function.

12.2

Functionality of PBX Cascading

Cascaded PBXs must be connected by means of a twisted-pair lead with RJ45 plugs. All eight pins of the lead must be wired 1 to 1. Both voice and administration data are transferred via this lead. Connect the lead to the PCM ports of the two MC+1-3 central control modules of the PBXs. The shielded CAT-5 lead must not be longer than 50 centimetres.

Note: Owing to the very short permissible lead length, the two PBXs have to be stacked. It is not possible to place them side by side.

Putting a Cascaded PBX into Operation

Proceed as follows to put a cascaded PBX system into operation:

If you want to cascade two OpenCom 510 PBXs, you will need to set the frame number using the DIP switches on the central control module.

To access the DIP switches, remove both central control modules (master and slave systems); proceed as described in

Installing the Central Control Module starting on page 29.

Set the DIP switches of both modules as follows:

DIP Switch Settings

Frame as Master

S1: open (switch set to “1”)

S2: open (switch set to “2”)

Frame as Slave

S1: closed (switch set to “ON”)

S2: open (switch set to “2”)

For the location of the DIP switches (S1and S2), refer to the illustration

Back up the master system data. For further information, refer to the online help topic SYS Configuration: Data Backup . The backup procedure also stores the current configuration data to the CompactFlash memory card.

Switch off the master system if it is operating. Disconnect the module from the power supply by pulling out the mains plug.

Connect the two modules by means of a suitable cable as described above.

Power on the two PBXs. The order in which you do this does not matter.

In the PBX Configuration: Ports: Slots dialogue of the master system’s Configurator, click on Slave . Select the slave Type in the Slave: Change dialogue.

146

PBX Cascading Putting a Cascaded PBX into Operation

Please note: If you change the type of slave system later on, the port settings that have been made will be deleted.

The master system then initialises the slave system. This may involve transfer of firmware (operating software) from the master system to the slave system. This can take a few minutes.

Configure the system telephone connected to the slave system for testing purposes in the Configurator . In the PBX Configuration: Ports: Upn dialogue, click on one of the additionally displayed entries of the type Upn 1/m/n

(1: slave system, m: slot number, n: U pn

port number).

Note: Changes to the configuration while initialising the slave system may trigger error reports referring to the ongoing initialisation.

You can see that the initialisation has been completed from the display on the system telephone connected to the slave system.

12.3.1 Notes

Observe the following when operating a cascaded PBX system:

■ All U pn

, S

and a/b ports of the slave system interface cards can be used with appropriate telephones. All features of system telephones on U pn

ports are available without restriction.

■ The S

ports of the slave system can also be used for trunk lines or for PBX networking (see

PBX Networking starting on page 149).

■ It is not possible to operate a DECT base station on one of the U pn slave system.

■ The ISDN-L1 reference clock signal is always transferred from the master to the slave system and must be acquired from an S

port –or preferably an S

port– on the master system. The master system therefore needs to be connected to at least one ISDN trunk line.

■ It is possible to operate an S

interface card of the type MS+S2M1-1 in the slave system. As the ISDN-L1reference clock signal supplied by an S

PBX Cascading Putting a Cascaded PBX into Operation card is not precise enough, you will also need to operate an S

interface card in the master system.

■ The slave system cannot be addressed directly through a LAN. For configuration, always use the Web console of the master system.

■ To operate the slave system again normally, you must reset it to its factory set-

tings (refer to Resetting the System Data starting on page 92 and

DIP Switch Settings on page 145).

12.3.2 Licensing Information

A licence is required for certain additional OpenCom 510 program packages, for example for the internal voice-mail system called OpenVoice .

The following information is for customers who have already obtained licences for an OpenCom 510 and would like to cascade or network their existing system with another OpenCom 510.

PBX Networking

If you network two OpenCom 510 systems with each other, you needn't generate any new activation keys but can continue to use the corresponding functions on the existing OpenCom 510. The “disadvantage” of this alternative is that you have to administer a separate configuration on each OpenCom 510.

PBX Cascading

In the case of PBX cascading, the master system administers the overall configuration.

If you have already installed activation keys on an existing OpenCom, they have to be ported to the master system.

In this case, new activation keys for the use of additional program packages must be generated on the Aastra DeTeWe licence server

(http://lizenz.aastra-detewe.de). The licensing confirmation for the cascading contains all the information you need to carry out this procedure.

Note: You will need the serial numbers of both infocom systems for porting the activation keys. The serial numbers can be found in the Web console's Configurator , in the System

Info: Versions menu.

148

PBX Networking Connections

13. PBX Networking

OpenCom 510 provides all the features necessary for PBX networking. You need

PBX networking in the following cases:

■ To operate the OpenCom 510 as a subsidiary system on another PBX. This will also allow you to use the OpenCom 510 as a DECT server, for example.

■ To network the OpenCom 510 with an OpenCom 1000. In this way you can use the OpenCom 510 as a PBX for a branch office, for instance.

■ To network several OpenCom 510s into a PBX system.

■ To use flexible configuration possibilities of trunk lines for a OpenCom 510.

All settings that affect the configuration of PBX networking can be found in the

Configurator menu PBX Configuration: Trunks and in the PBX Configuration:

System: Settings dialogue under System linking . Refer also refer to the corresponding help topics in the OpenCom 510 online help.

You can use ISDN point-to-point connections (Q.SIG or DSS1 protocol) or IP connections (Q.SIG-IP protocol) for TK system networking.

Note: If you do not need the features of PBX networking, the simplified configuration is sufficient in most cases. For this purpose, assign the preconfigured trunk groups (bundles) Multi-terminal access or System access to the ports.

The preconfigured route called External trunk now makes it possible to seize an external line immediately or by first dialling the prefix “0”. You can rename the preconfigured bundle and the preconfigured route if required, but you cannot delete them.

13.1

Connections

Networking two or more TK systems means interconnecting them. The

OpenCom 510 allows you to use the following connections:

■ ISDN trunk lines

ports or on the S

■ IP network connections (Q.SIG-IP)

PBX PBX PBX PBX

PBX

Trunk line

Point-to-point connection

Example of a PBX network

Various line types and transmission protocols can be used for point-to-point connections. The required network topology (distance, connection capacity) determines which type of point-to-point connection is most suitable.

13.1.1 Protocol: Q.SIG or DSS1

The Q.SIG protocol, designed for ISDN point-to-point connections, is the preferable choice as the transmission protocol; alternatively, the DSS1 protocol, designed for ISDN dial-up connections in the Euro-ISDN, can be used. Certain PBX networking features can only be used with the Q.SIG/Q.SIG-IP protocol, however.

In particular, the identifier indicating whether a call is internal or external cannot be transmitted using DSS1.

Both protocols implement communication on several protocol layers:

■ L1: Layer 1 defines the physical line properties and the electrical coding of signals.

■ L2: Layer 2 enables communication via individual error-protected channels that are independent of each other.

■ L3: Layer 3 defines the administration of the individual channels and implements the features designed for ISDN.

Note: All layers of the Q.SIG-IP protocol are symmetrical. The following are unnecessary: a Master/Slave setting, clock and synchronisation settings (please refer to

Connection via

Q.SIG.IP

starting on page 154).

150

PBX Networking Connections

13.1.2 Master/Slave

For an ISDN connection, it is possible to determine which PBX is the protocol master and which the protocol slave. This relationship can be determined for all three protocol layers independently of one another.

For each protocol layer, the PBX at the other end always has to be suitably configured. If one PBX is the protocol master for a layer, the other PBX must be the protocol slave for this same layer. Normally all three protocol layers are configured identically. In the case of a trunk line, the network operator is the protocol master for all three layers.

Note: In the case of an S

line, it is also possible to determine for each useful channel which end can administer a channel (master = internally seized or slave = externally seized). On S

lines this setting is determined by “L3 master” for both B-channels.

13.1.3 L1 Clock

To enable PBXs in the ISDN network to communicate with each other, they must be “clock-aligned”. The L1 protocol master sets the clock for layer 1, and the L1 protocol slave adopts (synchronises to) this clock.

When planning a PBX networking scheme, you must make sure that the L1 clock propagates from a master via a number of PBXs.

Trunk line

Point-to-point connection

Example: propagation of the L1 clock

If more than one port with the setting L1 Type = “Slave” is configured on an

OpenCom 510 and the setting L1 sync possible has been activated, then one of the ports is automatically defined as the L1 clock source. The OpenCom 510 will automatically switch the clock source to another port configured as an L1 clock source (if a line fails, for example).

151

PBX Networking Types of Point-to-Point Connections

LED 3 (top right) of an interface card will light up if one of the interfaces on the card has been selected as a clock source. If an S

interface of the type MT+S2M1-

1 is installed, it will be selected as the preferred clock source.

Please note: Reciprocal or circular application of the L1 clock is not allowed.

Example: In the above case you could reverse the L1 slave/master setting for the connection between PBX 1 and PBX 3. However, if you then activate the setting

L1 sync possible for the port of PBX 1, this may cause parts of the PBX network to stop functioning temporarily.

When applying the L1 clock of trunk lines, you can assume that the public network is “clock-aligned”. So, in the above example, you can connect additional trunk lines to one of the PBXs.

13.2

Types of Point-to-Point Connections

There are different types of connection available for an point-to-point connection between two PBXs, depending on the distance between them.

13.2.1 Direct Connection

This type of ISDN point-to-point connection joins the two systems directly to each other using a crossover twisted-pair cable. An S

connection can be used for distances up to 1,000 metres, while an S

connection can span up to 250 meters.

Normally one PBX is the protocol master for all three layers, and the other PBX is the protocol slave for all three layers.

13.2.2 Connection via an Active Transmission System

For distances exceeding the range of a direct connection, an active transmission system can increase the range to up to 50 km. Normally the L1 master is the transmission system for the two connected PBXs. For the protocol layers L2 and L3, one

PBX is normally the protocol master and the other PBX is the protocol slave.

Note: The active transmission system itself gets its L1 clock either from the network operator or from a clock generator connected by wire.

13.2.3 Connection via the Public Network

Point-to-point connections via the public network of a network operator can be used for bridging distances beyond 50 km. Due to the long distance involved, for technical reasons it is not possible to synchronise the L2 protocol. Consequently, the public network is normally the protocol master for protocol layers L1 and L2.

One PBX is therefore the L3 master and the other PBX the L3 slave.

PBX Networking Configuration

13.2.4 Connection via Q.SIG.IP

If you are operating a fast and continuous internet connection at two or more locations, you can establish the TK system networking via internet connection as well. The OpenCom 510 uses the Q.SIG protocol, for use with ISDN point-to-point connections and transports the protocol and voice data via IP connections.

The number of simultaneous conversations possible will depend on the capacity of the internet connection and the compression method used. A multiple S

2M point-to-point connection is simulated for each Q.SIG-IP bundle. This means that 5 virtual D channels and up to 120 voice channels are available. Both Media Gateway

Card channels and the Media Gateway software function can be used for Q.SIG-IP.

Q.SIG-IP connection data are subject to codec compression (please refer to

Voice over IP (VoIP)

chapter regarding

Fundamentals starting on page 110). Q.SIG-IP also

transfers the voice data directly from terminal to terminal via the RTP protocol. In certain cases, for example, when an incoming external call is placed via multiple TK systems, one or more RTP proxies may be used to forward the connection.

Currently, there are no standards for the necessary extensions to the Q.SIG protocol. This means that you can only use Q.SIG-IP between OpenCom systems.

Networking two OpenCom 510 systems using Q.SIG-IP requires 2 licences – one licence per system. The number of possible voice connections is not restricted by the licence.

Go to the PBX Configuration : Trunks : Bundle page in the Configurator to set up a Q.SIG-IP connection. Create a new bundle and select the Access type “System

Access”. Select “Q.SIG-IP” under Protocol . Configure the IP address of the other system, the port numbers to be used, the number of possible voice connections and select a VoIP profile for the codec selection. Please refer to the relevant help topics in the Online Help for the OpenCom 510 as well.

Note: Q.SIG-IP cannot be operated using a connection with

NAT. For a Q.SIG-IP connection, a branch connection or another VPN connection is required.

The possible configurations described below can be set up in the Web console using the PBX Configuration: Trunks menu.

13.3.1 Trunk groups

This is a group of lines of the same type and direction. A line can only be assigned to one trunk group (bundle).

Network operator

PBX 1 PBX 3

PBX 2

Bundle

Trunk line

Point-to-point connection

Example of a PBX network with trunk groups

In the above example, the following trunk groups are configured for PBX 1:

■ Two S

lines in a multi-terminal configuration to the network operator which are assigned to the “A” trunk group.

■ Two S

point-to-point connections to PBX 2 which are assigned to the “C” trunk group.

■ One S

point-to-point connection to PBX 3 which is assigned to the “E” trunk group.

Note: A line or a trunk group cannot be seized directly. It is always performed indirectly via a route.

13.3.2 Routes

A route is a group of trunk groups enabling a connection in one direction. If the first trunk group of a route is fully utilized, the next trunk group is seized (“trunk group overflow”). One trunk group can also be used for different routes.

In the above example, a route set up for PBX 1 allows a connection to PBX 2. Trunk groups “C,” “E” and “A” are assigned to this route. If a user connected to PBX 1 wants to reach a party in PBX 2, lines will be seized in the following order:

■ PBX 1 first searches for a free channel in the “C” trunk group.

155

PBX Networking Configuration

■ If all the lines in trunk group “C” are busy, the system tries to set up a connection via trunk group “E”. PBX 3 switches the connection through, provided it is appropriately configured (refer to

Numbering starting on page 156).

■ If it was not possible to set up an indirect connection via PBX 3, the system tries again via trunk group “A”. The “prefix” necessary for this can be configured with the route.

■ The user does not get a busy signal until the attempt to set up an indirect connection via the network operator has also failed.

Note: If an internal connection is switched via a network operator, the call is signalled using the external number of the calling PBX.

For each route you can define a randomly selectable code digit for seizing the route. You can also configure whether a user is authorised to seize a particular route, whether LCR is to be used for one of the trunk groups and the criteria

(business or private call, booking numbers) for evaluating call data.

13.3.3 Numbering

A user can seize a particular route by pre-dialling a specific code digit. With this

“open numbering”, a user must always dial this code digit and then the telephone number in order to reach a party in another PBX.

If none of the telephone numbers in your PBX network occur twice, you can also configure “closed numbering”, allowing the same telephone number to be used for reaching each user within the PBX network.

With closed numbering, the OpenCom 510 determines which route to seize from the telephone number dialled. The information needed for routing a call can be configured in a numbering table containing up to 100 entries. You use this table to assign telephone numbers and/or ranges of telephone numbers to a particular route.

A default entry in the numbering table makes it possible to seize a “default route” for all remaining unassigned numbers. In particular, this simplifies configuration of the OpenCom 510 as a subsidiary system: the only entry you assign to the default entry is the route to the host system

Route

Example of closed numbering tables

The automatic switching of call requests (i.e. routing) by means of trunk group overflow or default numbering can lead to “circular switching”.

To avoid this, a “transit” counter is incremented whenever a connection is switched through on Q.SIG lines. When the configured maximum value is reached, further switching stops.

13.4

Technical Details

A different PBX number must be set for each OpenCom 510 in a PBX network. This setting can be found in the Web console, in the menu PBX Configuration:

System: Settings under the heading System linking . You can also set the maximum value for the transit counter there. This value depends on the topology of the PBX network and should allow the system to have the maximum number of further connections possible.

You can display the connection status of the lines at any time in the Configurator menu System info: PBX: Trunks . You should check this in particular after making changes to a configuration to see whether all the lines used for system networking are operable.

Some of the features possible in Q.SIG are not supported by OpenCom 510 with all their options, for example callback on busy within the Q.SIG network. The call categories defined in Q.SIG (e.g. Emergency Call, Operator, Normal) and the Q.SIG name transmission feature (“user names”) are fully supported.

The code digits to be used for seizing a route with open numbering are not transmitted to the destination PBX and thus cannot be evaluated by it. To reseize a route (for example for a callback), you must set the appropriate digit prefixes in the trunk group configuration for the routes to be reseized.

157

PBX Networking

Tip:

Technical Details

If, for example, you are configuring a route which can be seized using routing code “5” and have selected one or more bundles for this route, change the Prefix for dest. call number at incoming internal setting to “5” for this bundle in order to enable the route to be reseized.

Introduction

14.1

Introduction

With the team functions you can manage your telephone communication tasks by assigning lines with separate call numbers to the keys of different terminals. The terminal users, or team members, can thus pick up one another’s calls or telephone each other using the configured keys.

Team functions can only be configured on the corded system telephones of the

OpenPhone 6x and OpenPhone 7x product line because only these have the required features.

Up to three of these keypad extensions can be used with a OpenPhone 75.

Note: Only one function or call number can be programmed for each call key.

The following keys can be used:

■ Trunk key : Calls (for the programmed call number, e.g. 11) are signalled to this key, and you can make internal and external calls via this number. A trunk key can be programmed with a substitute function (with another team member acting as the substitute). Calls for you are then signalled to the terminal of another team member. A trunk key also provides functions for managing calls.

For example, you can configure call protection if you do not want to be disturbed, or call diversion to another telephone.

■ Team key : As with a trunk key, a team key can be used to receive or make calls.

However, this key cannot be used to change the settings for managing calls; it is not possible, for example, to configure call diversion to another telephone.

Calls made via a team key are signalled to all terminals with a trunk key that has been programmed with the same number. For example, the team key with the number 11 calls all trunk keys with the number 11.

■ Busy key: The purpose of a busy key is to make the busy status of other team members visible. An incoming call for a busy team member is signalled on the other team member's busy key. That team member can take this call by pressing the busy key, which seizes his own terminal's trunk key. Calls taken via the busy key are not entered in the call list of the team member who was originally called. In addition, it is possible to call the respective team member via his busy key when his terminal is idle. You set up a call to this team member by pressing your own trunk key.

160

Team Functions Introduction

■ Direct call key : Only outgoing calls can be made with a direct call key; they are signalled to all terminals with the same number programmed to a trunk key.

Calls via a direct call key are signalled to the destination terminal even if that terminal has been programmed with a substitution function or call protection.

If the destination terminal has been configured for call diversion, the direct call is not diverted.

Which key is suitable for which purpose?

■ Trunk keys can be assigned call numbers for managing central communication tasks, for example, customer support. If the call numbers of the support department are assigned to trunk keys on all of its terminals, then all members of the support department can receive and manage calls and use the substitute function.

■ Team keys , for example, can be used to create a project group within a department. Calls from customers of this group can then be answered by any team member who is not busy. The team members can call each other by the team keys.

■ A busy key can be used to configure an enquiry station showing the status of the individual users. The enquiry station sees the status of the users and can put calls through by simply pressing the key.

■ Direct call keys , for example, can be configured at a terminal in a conference room to call the secretary.

14.1.2 Team Configuration

You can create teams and program call keys in the Configurator of the

OpenCom 510 ( PBX Configuration: Groups and Ports: Upn menu).

Call key 1 is preset as a trunk key on all system telephones. This setting can be changed by the system administrator.

Examples of Use

The following examples illustrate the various uses of teams and team functions.

For information on the display texts and how to use the individual functions, refer to the chapter “Managing Calls in a Team” in the “OpenPhone 61, 63, 65” or “Open-

Phone 71, 73, 75” user guide.

14.2.1 Executive/Secretary Team

In this example, the executive/secretary team comprises two members: the executive and the secretary. The secretary has one OpenPhone 73 system telephone, and the executive has two, one of which is used as a parallel telephone in a sofa suite.

Example: executive/secretary team

Line Seizure

The secretary can be reached on the call number 11 (trunk key TrK 11: secretary’s office).

The executive can be reached on the call number 10 (trunk key TrK 10: executive’s office). He can also answer calls from his parallel telephone. In addition, a private line is configured for both of the executive’s telephones (trunk key TrK 12: private).

162

Team Functions Examples of Use

Call numbers 11 and 10 are both configured as a trunk key on the executive’s and the secretary’s terminal respectively. Thus the executive and the secretary can use either call number (for answering as well as making calls). Each can act as a substitute for the other.

The secretary’s terminal also has the executive’s call number configured as a direct call number (DK 10: executive’s office). The secretary can therefore reach the executive and put through calls even if the executive has programmed a substitute.

Line Busy Indication

If a line is busy, e.g. TrK 11 secretary’s office, the other terminal will indicate this.

The executive’s private calls via TrK 12 are not indicated on the secretary’s terminal since no appropriate trunk key is configured on the latter’s telephone.

Call Signalling

In this configuration example, calls to one’s own call number are signalled acoustically on the following telephones:

■ Call number 11 on the secretary’s telephone

■ Call numbers 10 and 12 on the executive’s telephone.

Calls for the other team member’s call number are indicated by an optical signal on one’s own telephone (flashing trunk key LED).

The parallel telephone will indicate calls only by an optical signal.

Time-delayed acoustic signalling can be configured for TrK 10 on the secretary’s telephone. If the executive, for example, does not answer a call within 10 seconds, the secretary’s telephone will start to ring.

If the executive activates a substitute function with the secretary as the substitute, calls for call number 10 will be indicated on the executive’s telephone by an optical signal only, but signalled acoustically on the secretary’s telephone. The secretary can also activate a substitute function. Calls for call number 11 are then signalled acoustically on the executive’s telephone, and indicated by an optical signal on the parallel telephone and the secretary’s telephone.

Example: three-member team

Line Seizure

Each team member’s call number, e.g. call number 10 for Miller, is programmed as a trunk key on his telephone.

On the other telephones in the team, this call number is programmed as a team key (e.g. TK 10 on Johnson’s and Smith’s telephones). The team members can thus see which number a call is for and can answer it by pressing the appropriate team key.

The team members can call each other via the team keys. For example, Miller can call number 12 by pressing TK 12; the call is then signalled to Smith’s telephone on

TrK 12.

164

Line Seizure

Call numbers 10, 11 and 12 are programmed as trunk keys on each team member’s telephone (TrK 10 to TrK 12.

All team members can use these numbers for answering as well as making calls.

165

Team Functions Examples of Use

Tip: In this team configuration it is useful to program one of the function keys on each telephone with the “Hold” function. A call, e.g. for TrK 11, can then be put on hold by pressing the function key. If another team member then presses trunk key

TrK 11 on his telephone, he can accept the call. For further information on function keys, refer to the “OpenPhone 61, 63,

65” or “OpenPhone 71, 73, 75” user guide.

Line Busy Indication

If a line is busy, e.g. TrK 11 Johnson, the trunk keys on the other team telephones will indicate this.

Call Signalling

In this example, calls via all trunk keys are signalled acoustically.

14.2.4 Toggle Team

The toggle team described here illustrates how a large number of call numbers can be managed efficiently with the help of team functions.

Each team member has one OpenPhone 75 system telephone with all call keys programmed as trunk and team keys.

Example: toggle team

Line Seizure

Each team member is assigned seven call numbers, each programmed as a trunk key (TrK 10 to TrK 16 and TrK 20 to TrK 26). For each member, these trunk keys are programmed either as support numbers or hotline numbers.

The first support number and the first hotline number of each team member is programmed as a team key on the other member’s telephone, e.g. TrK 10 and

TrK 15 on Miller’s telephone as TK 10 and TK 15 on Johnson’s telephone. The assumption here is that most calls will go to the respective first call numbers, and team members can thus help each other out by answering one another’s calls.

On each telephone it is possible to toggle between the calls on individual lines, e.g. TrK 10 and TrK 11, by pressing the appropriate key (toggling).

167

Team Functions Examples of Use

Every call on a trunk key can be transferred to any other party by means of the R key. For more information, refer to the chapter entitled “Consultation, Toggling,

Transfer and Conference” in the “OpenPhone 61, 63, 65” or “OpenPhone 71, 73, 75” user guide.

Line Busy Indication

If a line is busy, e.g. TrK 10 on Miller’s telephone, the appropriate team key will indicate this, e.g. TK 10 on Johnson’s telephone.

Call Signalling

In this example, calls via trunk keys are signalled acoustically. Calls via team keys are indicated by a visual signal (the team key LED flashes).

168

Call Queue

15. Call Queue

Introduction

15.1

Introduction

A queue can be activated for the telephone numbers of any type of telephone, i.e. for system, analogue, ISDN and DECT telephones.

If a call number with a queue is busy, calls to this number enter the queue. The caller first hears an announcement (if function “Announcer at busy” is configured) and then a dial tone.

Calls which remain in the queue for too long are cleared from the queue. The caller then gets a busy tone. If all the positions in the queue are taken then any further calls also hear the busy tone.

The time until an external call is cleared from a queue is defined by the network operator. In Germany this is usually two minutes and in other European countries usually three minutes.

If more than one telephone number (e.g. trunk or team keys) has been configured for a telephone, separate queues are used for each number.

On the OpenPhone 65/OpenPhone 75 system telephone, additional calls are signalled by a brief tone in the loudspeaker and in the display. If calls are in the queue, a number at the beginning of the second line of the display on the

OpenPhone 65/OpenPhone 75 indicates how full the queue is. If more than one telephone number with a queue is configured on the telephone, the total number of entries are displayed.

Calls in a queue are handled by the OpenCom 510 in the following order of priority: instant connection, door calls, automatic recalls, VIP calls, then other internal and external calls. Sensor calls thus have priority over other calls, for example. Calls of the same priority level are switched in the order of their arrival.

The system administrator sets the number of calls that can be placed in a queue individually for each user group. The value can lie between “0” and “99”. The “0” value deactivates the ”Call queue” function for a user group. When the maximum number of calls in the queue is reached, further callers hear a busy tone.

Only calls which have a “voice” service indicator are administered in a queue.

169

Call Queue Introduction

Note: As calling fax machines often operate with the “voice” service indicator (e.g. on analogue ports), you should assign ports for fax machines on the OpenCom 510 to a user group without a queue.

Queues can be combined with the “forwarding,” “pickup” and “hunt group” functions, for example, in order to configure an enquiry station for an operator.

15.1.1 Activation of Queues

Queues can be activated on a per user group basis. On delivery the default set, for all preset groups, is off .

When using queues, it often makes sense to activate call waiting protection. For this purpose, “Call waiting protection” authorisation must be allocated to the user group, and call waiting protection must be activated on the terminal.

Furthermore it is sensible to combine queues with the “Announcer at busy” function. When a caller calls a subscriber who is busy then they will hear a “central welcoming text”, for example, “Here is company XYZ. You will be immediately connected”. The function “Announcer at busy” can be set in the PBX Configuration:

Call Distribution: Incoming menu. Central welcoming texts can be recorded using the program package OpenVoice .

You should configure a new user group (e.g. “Operators”) and activate the authorisations “Call queue”, “Call waiting protection” and, if necessary, “Call forwarding”.

If users belong to this group, a queue will be activated automatically for all telephone numbers assigned to them.

15.1.2 Call Forwarding

Forwarded calls of the forwarding type “Immediately” and “On busy” have priority over queues. The queue of the forwarding telephone is not used for forwarding calls in this manner.

During the configuration of this type of call forwarding, the contents of the queue are not transferred to the target terminal. If there are still calls in the queue when the call forwarding function is activated, these calls can only be accepted on the source terminal.

170

Call Queue Examples of Use

If a call is to be forwarded “After delay”, it enters the queue. If the call has not been answered before the delay period expires, it will be forwarded to the target terminal and can then be answered there.

15.1.3 Pickup

The functions “Pickup” (from a pickup group) and “Pickup selective” can be used together with queues. A user who accepts a call using “Pickup” or “Pickup selective” picks up the next call from the queue.

15.1.4 Hunt Groups

Hunt groups of the “parallel” type are usually used together with queues, with the queues of each telephone in the group being synchronised to each other. When a call to the number of the hunt group arrives, the call enters all parallel queues. If a call from one of the queues is answered, it is removed from all other parallel queues.

15.2

Examples of Use

15.2.1 Enquiry Station for an Operator with Two

System Telephones

The operator switches all incoming calls and can either work on the

OpenPhone 65/OpenPhone 75 or the mobile terminal, the OpenPhone 27.

Configuration

■ Configure the system access or access for multiple terminals under PBX Configuration: Ports: S

■ Configure the OpenPhone 65/OpenPhone 75 and e.g. a RFP 22/24 under PBX

Configuration: Ports: U pn

■ Configure a trunk key for the OpenPhone 65/OpenPhone 75 under PBX Configuration: System telephones .

171

Call Queue Examples of Use

■ Configure the OpenPhone 27 under PBX Configuration: Ports: DECT-PP and assign the OpenPhone 27 its own telephone number. Check in the

OpenPhone 27.

■ Under PBX Configuration: Call Distribution: Incoming or PBX Configuration: Call Distribution: Incoming PTP route all incoming calls to the number of the OpenPhone 65/OpenPhone 75 trunk key.

■ In the Configurator , create a new group called “Operators” under User

Manager: User groups . Activate “Call queue”, “Call waiting protection” and

“Call forwarding” for this group and set the Dial out: External option appropriately.

■ Create a user called “Operator 1” under User Manager: User . Assign this user to the “Operators” user group. Assign the telephone numbers of the

OpenPhone 65/OpenPhone 75 trunk key and the number of the mobile

OpenPhone 27 to this user.

■ Activate

Call wait. prot.

(call waiting protection) on both terminals in the

Protection

menu.

■ Configure a function key on the OpenPhone 65/OpenPhone 75 which activates/deactivates a “call forwarding immediately” to the telephone number of the mobile OpenPhone 27 (in the menu

Call diversion: Divert phone: Immediately

Use

Incoming calls are routed to the OpenPhone 65/OpenPhone 75 manned by the operator, who then puts the calls through. A queue is used so that callers do not get a busy signal. The display on the OpenPhone 65/OpenPhone 75 indicates how many calls there are in the queue.

If the operator wants to leave the workstation and take along the enquiry station, call forwarding to the OpenPhone 27 is activated by pressing a function key. Calls which are in the OpenPhone 65/OpenPhone 75 queue must still be answered on this telephone. New calls are signalled on the mobile OpenPhone 27 or enter its queue, allowing the OpenPhone 27 to be used as a mobile enquiry station.

On returning to the workstation, the operator deactivates call forwarding by pressing a function key. Calls which are already in the queue are switched on the mobile OpenPhone 27. New calls are signalled on the OpenPhone 65/

OpenPhone 75 or enter its queue.

172

Call Queue Examples of Use

15.2.2 Group of Three Enquiry Stations

The enquiry stations switch all incoming calls. Incoming calls are administered in queues. Depending on the number of arriving calls, one to three enquiry stations in this group are manned. The enquiry stations are each equipped with an

OpenPhone 65/OpenPhone 75.

Configuration

■ Configure the multi-terminal access or the system access under PBX Configuration: Ports: S

■ Configure the three OpenPhone 65/OpenPhone 75 telephones under PBX

Configuration: Ports: U pn

■ Configure a trunk key with its own telephone number for each of the

OpenPhone 65/OpenPhone 75 telephones under PBX Configuration:

Devices: System telephones .

■ Configure a hunt group of the “parallel” type under PBX Configuration:

Groups: Hunt Group , and include the three telephone numbers of the trunk keys in this hunt group.

■ Under PBX Configuration: Call Distribution: Incoming or PBX Configuration: Call Distribution: Incoming PTP route all incoming calls to the number of the hunt group.

■ In the Configurator , create a new group called “Operators” under User

Manager: User groups . Activate “Call queue” and “Call waiting protection” for this group.

■ In the User Manager , configure a u ser for each of the three operators and assign these settings to the user group called “Operators”. Allocate each User the telephone number of the trunk key of their system telephone.

■ Activate

Call wait. prot.

(call waiting protection) on all three terminals in the

Protection

menu.

■ Program a function key with the function “Sign on/sign off from hunt group” on the three system telephones (in the menu

Calls: Hunt group

173

Call Queue Examples of Use

Use

Incoming calls are signalled in parallel to all signed-on enquiry stations. If the enquiry stations are busy, the incoming call joins the queue on each of the terminals in the hunt group. If one of the enquiry stations accepts a call from the queue, the call is removed from the queues of all the other enquiry stations. The display at each enquiry station (OpenPhone 65/OpenPhone 75) indicates how full the queue is.

If attendants leave the station, they sign off from the hunt group by means of a function key. In contrast to Example 1, further calls do not have to be processed after the sign-off, as the calls are also registered in the queues of the other signedon enquiry stations.

Note: When the last enquiry station remaining in the hunt group signs off, further callers will hear the busy tone.

174

Multi-Company Variant

16. Multi-Company Variant

Communications systems are frequently shared by several companies. These companies want to jointly use the existing infrastructure (e.g. the existing lines and features of the system), while at the same time they wish to organise and pay for their communication completely independently of one another.

This “multi-company variant” can be implemented using the OpenCom 510 within a shared office, for example.

In the multi-company variant, the companies are essentially completely independent of one another. This allows them to have their own trunk lines, which is useful for billing purposes. The OpenCom 510 hardware and software are used equally by all the companies, however. It is possible to configure the

OpenCom 510 for each company and define the extent to which the features of the system may be used.

In brief, the features of the multi-company variant are as follows:

■ Up to five companies can be configured at the same time.

■ Every user of the OpenCom 510 is assigned to a company.

■ Each available trunk group or SIP account is uniquely assigned to a company so that incoming external calls can be transferred to the correct internal subscriber.

■ For each company, every route can have its own code. For example, it is possible to activate different routes with the code “0” for different companies. This enables separate charging for outgoing external calls, for example.

■ An individual exchange (“operator”) can be set up for each company.

■ Each company can maintain the communication data of its business partners in its own company telephone book.

■ The charges can be billed individually for each company.

175

Multi-Company Variant Configuring the Multi-Company Variant

16.1

Configuring the Multi-Company Variant

The multi-company variant can be commissioned and configured by the system administrator of the OpenCom 510 without any major effort. In the multicompany variant, the communications system behaves in exactly the same way as the single-company variant. This is particularly of interest to users who want to expand their own system and at the same time operate it in a group.

The process in brief:

The feature must be activated (see

Activating the Multi-Company Variant starting on page 176).

The required companies must be set up (see

Configuring and Managing Companies starting on page 177).

The users of the OpenCom 510 are assigned to the individual companies (see

Assigning Users starting on page 177).

In order that the OpenCom 510 can transfer incoming calls to the corresponding company (or its staff ) correctly, the existing trunk groups must be uniquely assigned to the companies (see

Assigning Trunk Groups/SIP Accounts starting on page 178).

In the case of outgoing external calls, the lines via which the members of a company can make a call must be defined (see

Allocating Routing Codes starting on page 178).

An exchange must be set up for each company so that the OpenCom 510 can correctly process statuses in which a call should be routed to the exchange (see

Configuring the Company Exchange starting on page 179).

16.1.1 Activating the Multi-Company Variant

To be able to configure several companies in the OpenCom 510, the “Multicompany variant” (OpenCompany 45) program package must first be activated.

This is done in the Configurator on the Web console in the SYS Configuration:

Licences menu . The licence confirmation you received with the program package contains all the information you require about how to proceed.

176

Multi-Company Variant Configuring the Multi-Company Variant

Only when this package has been activated are the fields required to configure the multi-company variant available in the other menus of the Web console, for example in the User Manager: User groups menu or in the PBX Configuration:

Trunks menu .

16.1.2 Configuring and Managing Companies

Up to five companies can be configured in the OpenCom 510. By default, one company with the name “Company 1” is predefined. All configuration settings, e.g. in the user groups or in the trunk group configuration, apply to this predefined default company if not other company has been selected.

Companies are set up and managed in the PBX Configuration: Companies menu:

■ A new company is created in this menu using the command New . Each company can be given a name up to 20 characters long. This name is then displayed in all configuration dialogue boxes in which company-specific settings can be defined.

■ In this menu a company can be deleted again using the command Delete . If a company is deleted which is still used at other places (in the user groups, for example), the respective configuration is changed to the default company.

■ The name of the default company can be changed, but the default company itself cannot be deleted.

16.1.3 Assigning Users

For each user you must define the company to which they belong. This assignment determines, for example, which company telephone book the user has access to and which company-specific configuration data apply to them.

As the OpenCom 510 manages users in groups, the assignment “user > company” is also established this way. The company to which each user group belongs must be defined for each group. A user group can only belong to one company, i.e. not to several. However, a company can have several user groups. It is therefore possible, in the same way as in the entire system, to allocate a range of authorisation rights for the use and configuration of features for each company.

177

Multi-Company Variant Configuring the Multi-Company Variant

When setting up a new User group (in the User Manager menu), you will find that the default company is predefined; another company can be assigned as long as no other companies have been set up.

16.1.4 Assigning Trunk Groups/SIP Accounts

Connections of the same type and in the same direction are arranged in a trunk group (e.g. S

0 multi-terminal connections). To be able to correctly transfer incoming calls to the members of the configured companies (the users) via the lines of a certain trunk group of the OpenCom 510, each of the available trunk groups must be assigned to one of the companies. This is necessary to be able to transfer incoming external calls to the correct company exchange in cases where the called internal subscriber cannot be reached (“Connection to Operator”), for example. SIP accounts can also be assigned to a company.

The assignment of trunk groups to companies is done in the PBX Configuration:

Trunks: Bundle menu. The assignment of trunk groups to companies is done in the PBX Configuration: SIP: SIP accounts .

For outgoing external calls which users set up via the lines of their company’s trunk group/SIP account, the assignment of the trunk group to the company is irrelevant: the charges are assigned according to the “source” principle.

Charges are billed to the company to which the user belongs who set up the connection. The OpenCom 510 recognises this on the basis of the assignment between user groups and companies and on the basis of the routing code with which a line of the trunk group/SIP account was seized. For more information, please see the following section.

16.1.5 Allocating Routing Codes

Routes are used for automatic and selective seizure of trunk groups or connections for external calls. It is possible to seize a route by predialling a code.

In the PBX Configuration: Trunks: Route menu, you can define which company can seize each route. An individual code for the seizure is allocated per route for each company. The OpenCom 510 ensures that during configuration no seizure code is allocated twice (for two different routes) for each company. If during configuration of a route no code is allocated for one of the configured companies, the route concerned cannot be seized by the members (user groups) of this company.

178

Multi-Company Variant Working with the Multi-Company Variant

16.1.6 Configuring the Company Exchange

An internal telephone number must be set up for each company which represents the exchange, i.e. “the operator”. The calls to specific extensions arriving at the exchange are routed to this number, for example, as are all external calls where the called subscriber (a user who belongs to this company) cannot be reached, as in the case of a timeout.

A company exchange is set up in the PBX Configuration: Operator menu. In this menu, you can specify an internal telephone number for each company and time group which then represents the exchange for this company.

16.2

Working with the Multi-Company Variant

All the features of the OpenCom 510 which the users may already be familiar with from the single-company variant are available in the multi-company variant. These features can be used to the same extent and can be used in exactly the same way.

The following section describes the features additionally available to the users in the multi-company variant.

16.2.1 Company Telephone Book

An individual company telephone book can be created for each company. In addition to this, “personal” and “central” telephone books exist:

■ A personal telephone book is available for each user.

■ The central telephone book can be used across the companies by all users of the OpenCom 510.

The company telephone book is a central telephone book for the whole company.

It is only available to the users/user groups who are assigned to this company. You can also define whether the members of each user group may edit the company telephone book or not.

The company telephone book is treated exactly the same way on the system terminals as the other types of telephone books. This means that the entries listed in the personal, central and company telephone books are displayed on the system phones at the same time.

179

Multi-Company Variant Working with the Multi-Company Variant

Users can also use the telephone book of their company with the OpenCTI 50

Web applications and phone book , assuming they are authorised to use these applications.

In addition, it is also possible to assign a user group with the authorisation to edit foreign company telephone books. This authorisation is useful if members of this group - e.g. the “Administrators” - service the entire system. Foreign telephone books can only be edited in the Configurator in the Phone Book menu.

The number of entries in a company telephone book is unrestricted. The

OpenCom 510 can manage up to 2,000 entries in all telephone books (in the central, personal and company telephone books).

16.2.2 Making Calls Between Companies

All users of the OpenCom 510 can make internal calls to one another, irrespective of which company they belong to. Calls between users from the different companies are therefore not subject to any restrictions.

16.2.3 Billing Charges per Company

In the Costs Web application you can output the charges for each company.

Users who are authorised to use this application can view the charges for each company.

Setting up TAPI

With a TAPI ( T elephony A pplication P rogramming I nterface) you can operate a CTI application ( c omputer t elephony i ntegration). Here, the CTI application uses the services of the OpenCom 510 with the help of the TAPI driver installed on a

Windows PC.

Many telephony functions, such as enquiry, toggling, three-party conference, pickup, call protection and call forwarding can be controlled using appropriate TAPIcompatible software.

Requirements

You require an active IP network connection between the PC and the communication system. CTI functions can be used only in conjunction with system telephones.

You must therefore have configured at least one user for a system telephone. In addition, you require a TAPI 2.1-compatible CTI application, for example the

Phone Dialer included in the Windows operating system.

Installing the TAPI Driver

General/Hardware

The OpenCom 510 is not functioning.

Make sure the mains plug is properly connected.

Plug another device into the mains socket to check whether there is any voltage.

The mains plug is connected, the mains socket is supplying output, but the

OpenCom 510 still does not function.

DANGER!

This device contains hazardous voltages. To make the system dead, remove the power plug from the socket.

Is the +3,3V/-42V LED illuminated?

If not, contact your service centre or an authorised dealer. The AC adapter plug of the OpenCom 510 may be defective.

201

Frequently Asked Questions Telephony

After restarting the OpenCom 510, nothing is indicated on the displays of any connected terminals.

It takes a short while for the OpenCom 510 to start up.

After the restart, check whether the activity LED flickers in a regularly interval. This indicates that the OpenCom 510 has started up correctly and is ready for operation. Further information can be found in the chapter

Modules starting on page 59.

If the OpenCom 510 has not restarted properly, reset the OpenCom 510 to its

original factory setting (refer to the chapter entitled Resetting the System Data starting on page 92).

19.2

Telephony

It is not possible to make external calls.

Check the connection between the NTBA and the OpenCom 510.

In the Configurator , check whether the external S

ports are configured correctly

( PBX Configuration: S

menu):

– Configuration of System- / Multi-terminal access OK?

– Port is connected to the NTBA?

– Faultless Cabling?

– Terminating resistors properly configured?

The OpenCom 510 is connected to an NTBA with a multi-terminal configuration. Why is it not possible to establish external connections?

With the original factory setting, an additional external S

port is set for an NTBA in the system configuration; this additional port will be used first to seize a trunk line.

Deactivate the corresponding S

port in the Configurator ( PBX Configuration: S

0 menu).

One of the telephones is not functioning at all.

Make sure the telephone has been properly connected.

Check also whether the appropriate port has been configured correctly in the

Configurator ( PBX Configuration: Ports menu).

202

Frequently Asked Questions Telephony

It is not possible to make external calls with one of the telephones.

Check whether a user is configured for the telephone. Otherwise the settings of the Guests user group are valid for the telephone. To standard, this user group has no external call authorisation.

Make sure the user configured for this telephone belongs to a user group with external line access ( Configurator , User Manager: User groups menu).

Check also whether the internal call number of this telephone has been configured for incoming call distribution ( Configurator , PBX Configuration: Call Distribution menu).

One of the features (e.g. call diversion) on one of the telephones cannot be used even though the feature has been configured in the Configurator of the

OpenCom 510.

Make sure the user configured for this telephone belongs to a user group that has access to this feature ( Configurator , User Manager: User and User groups menus). Some features cannot be used until the system PIN is changed.

Nothing is indicated on the display of one of the connected ISDN telephones.

You have connected the ISDN telephone to an external S

port (RJ-45 socket).

These ports are intended for connection to the NTBA only. Connect the telephone to an internal S

0 port (pressure terminal).

Calls can be made but not received with one of the ISDN telephones.

The internal call number that has been configured for this ISDN telephone in the

Configurator ( PBX Configuration: Ports: S0 menu) must also be configured as an MSN on the ISDN telephone itself. For further information, refer to the User

Guide of your ISDN telephone.

An ISDN telephone always rings, if another telephone on the S

bus is being called.

This case also requires configuring the MSN on the ISDN telephone (see above answer).

It is not possible to configure Call Distribution: Outgoing for multi-terminal access.

You have configured multi-terminal access and system access in parallel. All outgoing calls are therefore established via system access, and outgoing call distribution can be configured for system access only ( Configurator , Call Distribution menu).

203

Frequently Asked Questions DECT

A specific MSN can be seized for individual calls by means of a code number procedure. For further information, refer to the “OpenCom 100, Operation on

Standard Terminals”user guide.

What are some of the causes for problems when sending and/or receiving faxes?

In frequent cases, the reason may be found in a problem with the ISDN-L1 reference clock distribution. The L1 clock is delivered from the network provider. An unclean L1 clock distribution and the introduced signalling jitter is overheard by the human ear. Nevertheless, data and fax transmissions may be disturbed by the jitter. Please check, which ISDN lines will deliver the L1 clock. One of the installed

ISDN interface boards (MX+S01-8 or MT+S2M1-1) should show a steady green

light with LED 3. Details can be found under L1 Clock starting on page 151.

The fax data transfer possibly is routed via a compressing VoIP connection. Please verify, if the a/b port is configured with the “Fax” setting. For the VoIP connection, select a VoIP profile which includes the non-compressing G.711 codec.

19.3

DECT

The LED of the RFP 22/24 base station is flashing, but none of the DECT devices is functioning.

Make sure the terminal setting for the corresponding U pn

port is set to RFP 22/24

( Configurator , PBX Configuration: Ports: U pn

menu).

If multiple RFP 22/24 base stations are installed, the blinking LED indicates that synchronisation is not finished.

The LED of the RFP 22/24 is continuously lit up, but one of the cordless DECT devices is indicating “No connection”.

You have not registered this DECT device. Configure a port in the Configurator and start the enrolment procedure ( PBX Configuration: Devices: DECT Phones menu).

Is it possible to increase the time for the enrolment procedure?

You must manually enter the IPEI of the DECT device in the Configurator . The enrolment time is then increased to one hour ( PBX Configuration: Devices: DECT

Phones menu).

LAN

Why is it not possible to establish a network connection with the

OpenCom 510?

Check whether the LEDs for the switch and the PC’s network card are indicating a connection.

Check the LEDs for the LAN functions of the OpenCom 510.

To check whether there is a network connection with your OpenCom 510, enter the “ping IP address” command in “Run” in the Windows Start menu (e.g. ping

192.168.99.254).

How can I determine the IP address of the OpenCom 510?

To find out what the IP address is, enter the code number *182 on one of the connected system telephones.

The code-number procedure *183 also displays the network mask.

The network connection is functioning, but nothing is displayed in the browser.

Enter the complete IP address of the OpenCom 510 along with the protocol identifier, for example http://192.168.99.254/.

Check whether the browser has been configured for connection through a proxy server. If so, deactivate the “Connect through proxy server” setting.

Frequently Asked Questions Internet

You have just configured the OpenCom 510 via the network. Why is it not possible now to establish a remote data transfer network connection?

The network card and the communication (remote data transfer) adapter cannot be run with the same routing setting. Deactivate the network card before connecting via the dial-up network.

Our network has grown over time, with several segments connected by one central router. How can PCs from all segments connect to the OpenCom 510?

If several routers are configured for your network in different segments, you can enter extra static routes in the NET Configuration: LAN: Routes menu.

In our network the OpenCom 510 dynamically issues the IP addresses by

DHCP. Can I firmly assign the IP address for our internal server PCs (mail,

Web)?

You need a static address assignment for these PCs. Make the appropriate host assignment entries in the Configurator ( NET Configuration : LAN : Hosts menu).

Create a static DHCP entry for each host assignment in the NET Configuration :

LAN : DHCP Server menu. Activate “Dynamic and static address” for the DHCP server.

19.5

Internet

I cannot access our company Web site.

Outside your system, your company Web site is accessed at “www.firm.com”, but in the Configurator you have entered “firm.com” as the domain. Your company’s site URL thus counts as an internal URL and can only be accessed by entering the direct IP address. If required, change the domain setting in the NET Configuration : LAN menu.

Why do some Internet services not work even though they can be used when dialling in directly via a modem?

Some Internet services require an active connection coming from the Internet. But the configured filter rules prevent this. Plus, it is not possible to establish incoming

Internet connections with the PCs directly owing to the network address translation process.

It is possible to redirect incoming connections in the Configurator , menu NET

Configuration : Port Forwarding . You should secure the redirection target (PC or server) with a suitable firewall software.

Frequently Asked Questions Internet

It is not possible to access the Internet with the OpenPhone 27.

The requirement for this is that the set should be configured as Handset+data

(only with RFP 21/23). The telephone number used by the OpenPhone 27 to establish an Internet connection must also be specified in the respective user profile ( Configurator , User Manager: User menu).

With the OpenPhone 27, the Internet can be accessed either directly via the remote data transfer network or indirectly via RAS access on the OpenCom 510.

For direct access you can directly dial any provider. Indirect access uses the routing function of the OpenCom 510, accompanied by the configured security features, for example.

Directly via remote data transfer network

If the Internet is accessed directly via the remote data transfer network, make sure that

■ the remote data transfer network is properly installed on your PC and that the correct ISP access data is configured,

■ the internal number used by the OpenPhone 27 to establish the data connection is configured for outgoing call distribution ( Configurator , PBX Configuration: Call Distribution: Outgoing menu).

Indirectly via RAS access

If the Internet is accessed indirectly via RAS, the system administrator should make sure that:

■ permission has been given for Internet access via RAS ( Configurator , Net Configuration: Firewall menu),

■ an internal number is configured for RAS access ( Configurator , Net Configuration: Connections: RAS menu),

■ your user group has been granted RAS access rights ( Configurator , User

Manager: User Groups menu).

For information on the installation of software and on configuring Internet access, refer to the “OpenPhone 26/27” user guide.

A SIP connection only passes unidirectional voice. What is the reason?

You did not use the OpenCom 510 as internet router or the STUN server of the SIP provider is unavailable. You need to activate the SIP support at your internet

207

Frequently Asked Questions Internet router, such as “SIP-ALG” or “Full Cone NAT” functions. You can also use the

OpenCom 510 for internet access. Correct the STUN setting in the PBX Configuration : SIP Provider menu.

Is it possible to use Q.SIG-IP connections via an Internet access with dynamic

IP address?

Q.SIG-IP connections require a fixed IP assignment for technical and security reasons. Therefore you need an Internet access with a fixed IP address. It is possible to tunnel a Q.SIG-IP connection through a VPN connection. A VPN connection offers the possibility to determine the peer’s IP address with a DynDNS service during connection setup. VPN and DynDNS can be realized with external servers or routers.
