Features
The OpenCom 107 communications system is designed to be connected to an
ISDN basic access using the DSS1 protocol. System access (point-to-point) and multi-terminal access (point-to-multipoint) are both supported. The two forms of access can be configured in parallel.
For this purpose, the OpenCom 107 has a total of four S
0
ports (one external, one internal and two that are switchable between internal/external).
The firmware of the OpenCom 107 is designed for configuring up to 150 users.
You can connect the following devices to the OpenCom 107:
■ analogue terminals
■
Euro-ISDN terminals
■
ISDN telephones (on the U pn
port) OpenPhone 52
■
DeTeWe system telephones
■
DeTeWe RFP 22 and RFP 24 base stations and DECT handsets (via an RFP 22/24 base station)
An S
0
port can be used by Euro-ISDN terminals working in accordance with DSS1.
A U pn
port is suitable for the OpenPhone range of DeTeWe system telephones and for the DeTeWe RFP 22/24 base stations. An analogue port is used by standard analogue devices.
If the CNIP (calling name identification presentation) feature is supported by your network provider, the latter will show you the name of callers in addition to their number for each incoming trunk call. The OpenCom 107 supports the display of the name on system telephones. However, if you have created an entry in the telephone book of the OpenCom 107 under the number of the caller, this will be displayed instead.
The OpenCom 107 can be integrated into an existing network (LAN) and be used by all workstations as an Internet access router and mail client.

Features
Configuration and programming of the OpenCom 107 is performed by means of a special Web browser (known as the “Web console”), which can be run on a connected PC.
The OpenCom107 can also be configured at the customer service centre and maintained by means of remote configuration.
A PC can be connected to the COM port for the purpose of configuring the system or transferring connection data.
To connect the OpenCom 107 with the existing company hardware, you can connect to any analogue port an door intercom (for example of the type “T-Com
DoorLine” or “Siedle DoorCom”). These can be used to operate a door opener and a doorbell via the system, for example.
The OpenCom 107 allows you to use CTI (Computer Telephony Integration) applications made by other manufacturers. This requires installation of a TAPI driver on
a Windows PC (see Setting up TAPI starting on page 117). The OpenCom 107 also
has an integrated dialling wizard: the OpenCTI 50. Via the OpenCTI 50 users can call up and use telephone functions on PCs without first having to install a special
TAPI driver.
The OpenCom 107 complies with the regulations for telecommunications equipment. The DSS1 protocol is implemented.
Packet data in the D channel
Some business applications, for instance POS terminals, cash registers or credit card terminals, require a permanent data connection over the X.25 packet data network. Packet data transfer through the ISDN D channel (according to X.31 via
SAPI 16) can also be established between several S
0
interfaces of the
OpenCom 107. Simultaneous connections are distinguished by means of a TEI
(Terminal Endpoint Identifier).
X.31 packet data can be forwarded between two S
0
interfaces (for instance an internal and external S
0
interface). Equally, data can be forwarded (“routed”) over permanent Q.SIG lines. Data can also be routed over an S
2M
interface. It is possible to operate multiple terminals with the same TEI on different internal S
0
interfaces.
A TEI mapping table allows these X.31 connections to be routed to the same external S
0
interface.

Features
The routing table for X.31 packet data is set in the Configurator under
PBX Configuration: X.31. Additional information can be found in the Configurator online help files.
Internet Access
It is possible to connect individual PCs to the OpenCom 107 via the internal S
0 ports, or to connect an entire LAN to the OpenCom 107 via the Ethernet port.
These PCs can access the Internet via the OpenCom 107. If Internet access is already available from an Internet service provider, this can be configured in the
OpenCom 107. If the client network is not IP-capable, the OpenCom 107 can administer the IP configuration necessary for Internet access. The OpenCom 107 has an integrated DHCP server and a DNS server, which in this case take over IP address administration and name resolution for the client PCs.
The OpenCom 107 enables Internet access for all connected PCs by means of a common IP address. Only this is externally visible. The local IP addresses of the client PCs are translated to the IP address of the OpenCom 107 by network address translation (NAT). In this way the client PCs in the LAN cannot be reached directly from the Internet. This protects them from direct external attack. The LAN is additionally protected by the OpenCom 107 filter lists, which can be customised individually (firewall function).
Note: We recommend you to read through the explana-
tions under Useful Information on Internet Access starting on page 63.
DECT Data Communication
The OpenPhone 27 DECT terminals enable PCs that are not connected to the
OpenCom 100 via the internal S
0
ports or the Ethernet interface to access the
Internet. These PCs can make full use of all the Internet and e-mail features of the
OpenCom 100.
Data is transmitted via the internal data interface of the OpenPhone 27. For this the OpenPhone 27 is connected with the serial port of the PC. The Internet can then be accessed directly via the remote data transfer (i.e. dial-up) network. The
OpenPhone 27 sets up a data connection with the OpenCom 100 via the DECT air interface. The remainder of the connection set-up is either direct - through an
ISDN B-channel - or indirect - through the internal RAS access of the
OpenCom 100. Indirect RAS access is preferable. This uses the routing function of the OpenCom 100 and thus also the security features of the shared Internet access.

Features
For detailed information on the installation of the required driver software and the various types of configuration, refer to the user guide for the OpenPhone 27.
For information on configuration of the OpenPhone 27 with a data interface, please refer to the online help documentation of the OpenCom 100.
E-mail
The OpenCom 107 has an integrated e-mail function that is able to use the POP3,
APOP or IMAP4 protocols to check the Internet service provider for incoming mail.
When configuring the OpenCom 107, e-mail account query can be configured for every member of staff. The OpenCom 107 then fetches the incoming e-mail headers (subjects) and senders from the mail server at set intervals, and forwards them to users’ 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 107 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.
Further Network Features
You can offer staff the possibility of dialling into the LAN by means of RAS access.
A LAN-to-LAN link can also be implemented by ISDN. In this way two
OpenCom 107s can connect their LANs by dial-in on demand.
A NET-CAPI program (driver software on the system CD-ROM) allows you to use
ISDN functions on those PCs that do not possess a built-in ISDN card.
Further Telephony Features
Installing an extra memory card allows you to operate a digital voice memory and voice information system. For more information, refer to the user guides called
“OpenVoice” and “OpenAttendant”.
You can optimise your telephone communication by using the team functions and the call-queuing function.
As your company’s requirements grow, the OpenCom 107 can be networked with other telecom systems. The OpenCom 107 can then operate as a sub-system or
DECT server. To operate the system as a DECT server the system’s U pn
ports must
10
Features be DECT-capable. It is also possible to create a telecom system with several networked telecom installations.
Voice over IP (VoIP)
The OpenCom 107 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 66).
