Product Enhancements. AT&T MERLIN LEGEND Release 3.1, MERLIN LEGEND Release 4.0

Product Enhancements

Forced Idle Reminder Tones

The forced idle reminder tone is a high-low “doorphone” tone ¾ 400 ms of

667 Hz tone followed by 400 ms of 571 Hz. The tone is provided under the following circumstances:

■ At the extension, to remind the user that the system or the extension is in the forced idle state

■ At the programming console or at a PC running SPM, to remind the system manager that the system (or at least one extension) is in the forced idle state because of administrative activity

In Release 1.1 and higher of the communications system, forced idle reminder tones occur every 20 seconds. You can adjust the volume of these tones with the volume control.

Product Enhancements

Several enhancements were implemented for Releases 1.1, 2.0, 2.1, 3.0, and

4.0. This section briefly describes these enhancements and new features. See the Feature Reference and the Equipment and Operations Reference for details about each enhancement.

The procedures that cover these enhancements are included in this book.

System planning for the enhancements is included in System Planning .

Release 1.1 Enhancements

Refer to Release 1.1 Notes for detailed descriptions of Release 1.1

enhancements. Release 1.1 includes all Release 1.0 functionality plus the enhancements described in the following sections.

Language Selection

This selection allows you to program the system for the display of prompts, menus, and messages on MLX display telephones in English, French, or

Spanish. You can also program the following options in any of these languages, independently of the system language:

■ Individual extensions with MLX telephones

■ System Programming and Maintenance (SPM)

■ System programming reports

■ SMDR report headers

Programming Basics 1–45


MLX-10D ä , MLX-20L ä , and MLX-28D ä display telephones and MLX-10 ä nondisplay telephones are available in three separate versions, with factory-set buttons in English, Spanish, or French. (The MLX-10DP ä is available in the

English version only.) In addition, user and operator guides and telephone tray cards are available in all three languages.

Programming and Maintenance

Programming and maintenance enhancements include the following:

■ Additional Inspect capability in system programming

■ Editing capability (Backspace selection) in extension programming

■ Improvements to system reports

■ An access log that records the last 20 times maintenance or system programming has been accessed

■ Longer (20-second) gap between ring cycles for programming mode and

Forced Idle tone

Operational

System operational enhancements include the following:

■ Automatic selection of an SA button when Conference is invoked

(Hybrid/PBX mode)

■ Prompting through Conference feature on MLX display telephones

■ Relocation of the More prompt on the MLX-20L display

■ Display of the number saved on a programmed Last Number Dial or

Saved Number Dial button when the button is inspected

SPM

SPM enhancements include operation in English, French, or Spanish, faster backup and restore, and automatic on-screen display of reports as they are created, with a Browse capability for reading the reports.

MLX-10 and MLX-10D telephones. The 8102 and 8110 telephones are also compatible with Release 1.0.

1–46 Programming Basics


PF Registration

PF registration number AS5USA-65646-PF-E is assigned by the FCC for operating the MERLIN LEGEND Communications System in Hybrid/PBX mode in the United States. (The PF registration is also applicable to Release 1.0

systems.)


Refer to Release 2.0 Notes for detailed descriptions of Release 2.0 and later enhancements. Release 2.0 includes all Release 1.1 functionality plus the enhancements listed below.

Programming

Programming enhancements include the following:

■ Extension Copy is a feature that reduces programming time by allowing the use of any extension as a template for programming another extension or block of extensions through centralized telephone programming.

■ Integrated Administration provides a single interface through Integrated

Solution III (IS III) for programming entries common to the MERLIN

LEGEND Communications System and AUDIX Voice Power ä .

■ Any SPM Version 2.xx (where xx is replaced by numbers) provides a

Convert function for use in upgrading the system from Release 1.0 or 1.1.

This function converts a backup file from a Release 1.0 or 1.1 system to

Release 2.0 and later format, allowing reuse of existing system programming on the upgraded system.

■ Forced idle reductions keep system interruptions at a minimum. In general, the smallest necessary component is forced idle during programming activities. For example, renumbering a single extension idles only one extension. Only a few systemwide programming activities, such as setting the system mode and system renumbering, idle the entire system.

Operational


■ Coverage VMS Off is a feature that prevents incoming outside calls from going to voice mail. (All other coverage remains active as programmed.)

The feature is programmed extension by extension, either through extension programming or through centralized telephone programming.



■ A Night Service group can be programmed to include either extensions or a calling group as members. However, you should not program both individual extensions and a calling group into the Night Service group, because individuals will not have a chance to answer before calling group members do.

■ When AUDIX Voice Power sends a Leave Message notification to an extension, the system identifies the voice mail system as the sender of the message. When the voice mail subscriber uses the Return Call feature, the call goes to any available voice mail port, not just to the specific port that generated the message. This reduces the chance of getting a busy port.

■ Coverage receivers can call coverage senders and have the call receive coverage treatment. If a receiver calls a sender for whom he or she is covering, and the sender is busy or unavailable, the call proceeds to other points of coverage. It does not come back to the receiver who originated the call.

■ Enhancements to display prompts include automatic posting of a Do Not

Disturb message (for MLX display telephones or other multiline telephones, a Posted Message button must be programmed for the Do Not Disturb message to be posted automatically). when a user activates the Do Not

Disturb feature, and confirmation messages when a user activates Hold,

Privacy, Saved Number Dial, and Transfer.

■ Direct Inward Dialing (DID) trunk emulation on a T1 facility provides up to

24 DID channels on a single DS1 interface, instead of requiring 24 separate physical trunks.

■ A telephone user can send a timed flash (switchhook flash) on a loop-start trunk call on a System Access ( SA ) button.

Fax Attendant System

ä

Fax Attendant is an application for sending and receiving fax messages; its interface is similar to the voice mail interface provided by AUDIX Voice Power.

Fax Attendant System, which co-resides with AUDIX Voice Power on the IS III platform, provides the following services:

■ Fax Call Coverage.

Receives and holds messages for subscribers whose fax machines are busy or out of paper. This service also allows a subscriber to have a personal fax number without having a fax machine.

■ Fax Mail.

Allows subscribers to create and use fax distribution lists, send and receive fax messages, and record personal greetings for incoming fax calls.

■ Fax Response.

Prompts callers to select and receive faxes from a customer-created menu of choices, using touch-tone responses.



408 GS/LS-MLX Module

The 408 GS/LS-MLX module (Releases 2.0 and higher only) combines four line/trunk jacks for ground-start or loop-start trunks and eight extension jacks for

MLX telephones on a single module in the control unit.

Primary Rate Interface (PRI)

Primary Rate Interface (PRI) enhancements include the following:

■ Connectivity to the 5ESS â Generic 6

■ Multiple incoming calls to directory number

■ Call-by-Call Service Selection

■ Password handling for FTS2000

■ Extension ID as Calling Party Number for Automatic Number ID (ANI)

Maintenance

Maintenance enhancements include the following:

■ Clear descriptions of module test failures

■ Optional printing of hard copy of error logs

■ Display that correlates extension numbers to slot/port and logical ID

■ Display showing which slots, trunks, and extensions are maintenance busy

■ Internal digital switching element (DSE) loopback test for all modules

■ B-channel loopback test for MLX modules

■ B-channel line or call service states display

■ Error log entries for dual-port RAM errors


Refer to Release 2.1 Notes for detailed descriptions of Release 2.1

enhancements. Release 2.1 includes all Release 2.0 functionality plus the enhancements listed below.



Operational


■ When a call is forwarded to a multiline telephone that has an Auto Dial or

DSS button programmed for the forwarding telephone, the green light next to the Auto Dial or DSS button for the forwarding telephone does not flash.

■ People answering calls received on Cover buttons are allowed to generate touch tones if their telephones are not outward- or toll-restricted.

■ Calls received on personal lines with Do Not Disturb on go immediately to coverage instead of waiting for the coverage delay interval.

■ A call put on hold at a Cover button can be added to a conference by someone who has a personal line for the call.

■ A call put on hold at a Cover button can be picked up by any person who has a personal line for the call.

■ Calls that have been put on hold at a Cover , SA , Shared SA , or Pool button can be picked up by a person who has a personal line button for the call.

■ An inside call on hold at an SA button can be picked up and transferred by any person with a Shared SA button corresponding to the button with the held call.

■ Calls that are on hold awaiting transfer can be picked up by any user who has a personal line for the call.

■ Beginning with Integrated Solution III Version 1.2, the automatic reconciliation program that was run automatically at 3:00 a.m. has been disabled and can be invoked manually from the User Maintenance menu.

■ When a telephone is programmed for Forced Account Code Entry, account codes do not have to be entered when using a programmed

Loudspeaker Paging button. In addition, an SMDR record is not generated for calls made to paging ports.

■ When an MLX telephone, other than an MLX-20L, is plugged into an MLX port and the Personal Directory does not contain any entries, the allocation of the Personal Directory resource is released. If there are any entries in the Personal Directory, the Personal Directory allocation and the entries in the Personal Directory are saved in the MLX port.

■ SMDR call records for calls made on PRI facilities are more accurate than

SMDR call records for calls made on non-PRI facilities. Outgoing calls made on PRI facilities receive “answer supervision.” Consequently, SMDR timing for calls made on PRI facilities begins when the call is answered.

Timing for calls made on non-PRI facilities begins when dialing is completed. Therefore, an SMDR call record is not generated when a call made on a PRI facility is not answered at the far end.



■ The Call Type field and the Called Number field on the SMDR report have been changed for both the Basic and ISDN report formats.

■ An 012 port that is programmed as a generic voice messaging interface

(VMI) port can transfer an outside call to an outside number.

■ In a system where the transfer audible option is programmed for Music

On Hold and a music source is provided, outside callers who are transferred to a calling group and are waiting in the queue or who are parked or camped-on, hear music while they are waiting. Internal callers never hear music on hold while waiting in the calling group queue or when they are parked, camped-on, or being transferred to another extension.

Installation and Hardware

Installation and hardware enhancements include the following:

■ The control unit covers for the MERLIN LEGEND Communications System are the same easy-to-use covers as those for the MERLIN II

Communications System.

■ A new 012 (T/R) module [apparatus code 517G13 (28) or higher letter] contains a built-in ring generator. The maximum ring equivalency number

(REN) supported is 2.2, and the module will ring four ports at one time.

Bridging of single-line telephones is not supported due to poor transmission quality.

■ A new 008 OPT module (labeled “with RING GEN.”) contains a built-in ring generator. It rings four ports at a time.

■ Stations and facilities in Maintenance Busy (both manual and automatic) can be identified by the maintenance monitor

User Features

Security

The Remote Access feature allows people at remote locations to enter the system by dialing the number of a line or trunk designated for remote access.

The system can be programmed to require the remote user to dial a barrier code

(a type of password) after reaching the system. In earlier versions, the systemwide barrier code length is fixed at 4 digits. Release 3.0 allows a systemwide barrier code length ranging from a minimum of 4 digits to a maximum of 11 digits, with a factory setting of 7 digits. SMDR records are enhanced to provide information for remote access calls. If the remote access call is received on a facility providing Caller ID information (see below), the

SMDR report can help trace the call.



Caller ID

Caller information (telephone number) is furnished to MLX display telephones by an 800 GS/LS-ID module using the LS (loop-start) option. This allows customers to screen calls prior to answering the phone, as well as providing calling party information for use with various applications. This function is only available when the customer subscribes to caller identification service from the telephone company, if the telephone company supports that service.

Shared System Access (SSA) coverage.

Authorization Codes

The Authorization Code feature allows you to make calls using your calling privileges when you’re dialing from an extension other than your own. When you enter your authorization code (ranging from 2 to 11 characters and unique across the system), the privileges and restrictions assigned to your home extension override the current restrictions at the host extension. This includes toll restriction, outward restriction, Facility Restriction Level (FRL), Allowed Lists,

Disallowed Lists, Night Service Exclusion List, and Dial Access to Pools. All other functions on the telephone are those of the local telephone, not the home extension.

Authorization codes can also be used for the purposes of call accounting through the SMDR printout. The SMDR account code field can hold the authorization code extension number or the authorization code itself.

Direct Voice Mail

If your company has voice mail, this feature allows you to dial a co-worker’s voice mailbox directly without ringing that person’s extension. Direct Voice Mail is especially useful for transferring calls when a co-worker is not available.

Additional Features

The status of Leave Word Calling (LWC) and Privacy are retained across cold starts.

Caller ID (CLASS

SM

ICLID and PRI) are available on primary coverage and return from transfer.



Additional Application Packages, Adjuncts, and

Adapter Enhancements

Fax Broadcast.

Provides a simple way to send one fax to as many as

1000 fax numbers.

Call Accounting System (CAS) for Windows

This stand-alone version of CAS takes advantage of the easy-to-use graphical environment offered by Microsoft Windows. Through data communications, it also allows one CAS system to serve multiple business sites.

Group Video Conferencing

Group video conferencing is supported over DS1 (Digital Signal Level 1) facilities with PRI. (Video conferencing has been available since Release 2.0.)




Release 3.1 includes all Release 3.0 functionality plus the enhancements listed below.

Security Features

New security features include a variety of components. Additional details are included elsewhere in this book.

Call Restriction checking for star codes

Beginning with Release 3.1, the system manager can now add star (*) codes to

Allowed and Disallowed Lists to help prevent toll fraud. Star codes, typically dialed before an outgoing call, enable telephone users to obtain special services provided by the central office (CO). For example, in many areas, a telephone user can dial *67 before a telephone number to disable central office-supplied caller identification at the receiving party's telephone. (You must contract with your telephone service provider to have these codes activated.)

When users dial star codes, the MERLIN LEGEND system's Calling Restrictions determine whether the codes are allowed. If allowed, the system's Calling

Restrictions are reset, and the remaining digits that the users dial are checked against the Calling Restrictions.

Trunk-to-Trunk Transfer on a per-station basis

This enhancement to the trunk-to-trunk feature enables the system manager to allow or disallow trunk-to-trunk transfer on a per-station basis. Beginning with

Release 3.1, the default setting for all stations is restricted.

Programmable Second Dial Tone Timer

Beginning with Release 3.1, the system manager can now assign a second dial tone timer to lines and trunks to help prevent toll fraud (for example, when star codes are used). After receiving certain digits dialed by a user, the CO may provide a second dial tone, prompting the user to enter more digits. If this second dial tone is delayed, and the user dials digits before the CO provides the second dial tone, there is a risk of toll fraud or the call being misrouted. The second dial tone timer enables the system manger to make sure that the CO is ready to receive more digits from the caller.

A Disallowed List containing numbers frequently associated with toll fraud

Beginning with Release 3.1, Disallowed List #7 now contains default entries, which are numbers frequently associated with toll fraud. By default, Disallowed

List #7 is automatically assigned to both generic and integrated VMI ports used by voice messaging systems. The system manager must manually assign this list to other ports.



Pool Dial-Out Code restriction for all extensions by default

Beginning with Release 3.1, the default setting for the Pool Dial-Out Code restriction has changed to restricted. No extension or remote access user with a barrier code has access to pools until the restriction is removed by the system manager.

Outward restrictions for VMI ports by default

Beginning with Release 3.1, ports assigned for use by voice messaging systems

(generic or integrated VMI ports) are now assigned outward restrictions by default. If a voice messaging system should be allowed to call out (for example, to send calls to a user's home office), the system manager must remove these restrictions.

!

Security Alert:

Before removing restrictions, it is strongly recommended that you

read “Appendix A: Customer Support Information.”

New default Facility Restriction Level (FRL) for VMI ports

Beginning with Release 3.1, the default FRL for VMI ports has changed to 0, restriction all outcalling.

New default FRL for the Default Local Route Table

Beginning with Release 3.1, the default FRL has changed to 2 for the Default

Local Route Table. Now, system managers can easily change an extension default of 3 to 2 or lower in order to restrict calling. No adjustment to the route

FRL is required.

New maintenance procedure for testing outgoing trunk problems

A password is now required for technicians to perform trunk tests.

!

Security Alert:

The enhancements in Release 3.1 help increase the security of the

MERLIN LEGEND System. To fully utilize these security enhancements, be sure to read and understand the information in these upgrade notes.




Release 4.0 includes all Release 3.1 functionality plus the enhancements listed below:

Equipment

New 016 tip/ring module

This new module supports the 200 station dial plan by providing sixteen ports for tip/ring devices. Applications that use a tip/ring interface can connect to this board. All sixteen ports can ring simultaneously. Four touch-tone receivers

(TTRs) are included on the module as well. The module's ringing frequency

(default 20 Hz) can be changed through programming to 25 Hz for those locations that require it.

New 800 NI-BRI module

This new module connects NI-1 BRI trunks to the MERLIN LEGEND system for high-speed data and video transmission.

Ssytem Features

Support for up to 200 stations

Release 4.0 has an expanded dial plan that supports up to 200 tip/ring devices.

Support for National ISDN BRI Service

This service provides a low-cost alternative to loop-start and ground-start trunks for voice and digital data connectivity to the Central Office. Each of the two B

(bearer)- channels on a BRI line can carry one voice or one data call at any given time. The data speeds on a B-channel are up to 14.4 kbps for analog data and up to 64 kbps for digital data, which is necessary for video conferencing and other video applications. Release 4.0 supports the IOC Package "S" (basic call handling) service configuration and Multi-Line Hunt service configuration on designated CO switches.

Support for 2B Data applications

Release 4.0 has certified group and desktop video applications that use two Bchannels to make video/data calls from endpoints (stations) that are enabled to use 2B Data. The endpoints that support these applications connect to an MLXport on the MERLIN LEGEND system. 2B Data applications can make use of the

NI-1 BRI, PRI, or T1 Switched 56 network interfaces to make outside connections using one or two data channels at a time.



Support for T1 digital data transmission

Release 4.0 expands its T1 functionality by providing access to digital data over the public switched 56 kbps network in addition to data Tie-Trunk services.

Users who have T1 facilities for voice services can now use them for video calls at data rates of 56 kbps per channel (112 kbps for video calls using two channels). The Release 4.0 T1 offering also includes point-to-point connectivity over T1 Tie-trunks, allowing customers to connect two MERLIN LEGEND

Communications Systems or a MERLIN LEGEND Communications System with a

DEFINITY

â

Communications System. The two communications systems can be co-located or off-premises.

Downloadable Firmware for 016 T/R board and the NI-BRI board.

The PCMCIA technology introduced in Release 3.0 continues to support these two new boards in Release 4.0 for installation and upgrade. A Release 3.0 or later processor is required for PCMCIA technology.

User Features

Delayed Call Forwarding

Each user can program a Forwarding Delay setting for the Forward, Remote Call

Forwarding, or Follow Me features. The forwarding delay is the number of times that a call rings at the forwarding extension before the call is sent to the receiver.

During the delay period, the user can screen calls by checking the displayed calling number (if it is available). The delay can be set at 0 to 9 rings. The factory setting for Forwarding Delay is 0 rings (no delay).

Voice Announce on the QCC

The QCC operator can enable the fifth Call Button to announce a call on another user’s speakerphone if the destination telephone has a Voice Announce capable

SA button available. A QCC cannot receive Voice Announce calls; they are received as ringing calls. The factory-set status for the fifth Call Button is to have

Voice Announce disabled.

Time-based option for overflow on Calling Group

Release 4.0 has added a time limit for calls in queue in addition to the previous number limit. If the Overflow Threshold Time is set to a valid number between 1–

900 seconds, calls that remain in the Calling Group Queue for the set time are sent to the Overflow Receiver. If the Overflow Threshold Time is set to 0,

Overflow by time is turned off. The factory-set time limit is 0 seconds (Overflow by time off).



Single-Line Telephone Enhancements

■ Disable Transfer.

Through centralized telephone programming, the system manager can disable the ability to transfer calls by removing all but one SA or ICOM button from the telephone.

■ No Transfer Return. When a handset bounce in its cradle, the MERLIN

LEGEND system interprets that as a switchhook flash and attempts to transfer a call. When the transfer attempt period expires, the user's telephone rings. Release 4.0 eliminates this unintended ringing by disconnecting the call in situations where a switchhook flash is followed by an on-hook state when dial tone is present.

■ Forward Disconnect. All ports on 012 and 016 modules now send forward disconnect to all devices connected to them when forward disconnect is received from the CO. This enhancement prevents the trunk/line form being kept active when one end disconnects from the call.

If an answering machine is connected to the port, it will not record silence, or busy tones, or other useless messages. This is a non-administrable operation.

Security Features

7-digit password for SPM

Release 4.0 has increased system security by requiring a 7-digit password when using SPM to perform remote administration or when performing the Trunk Test procedure. This password is to be used in addition to the Remote Access barrier codes.


Programming with SPM

2

The System Programming and Maintenance (SPM) software package offers an alternate method of programming the MERLIN LEGEND Communication System using a PC. This method frees the system programming console for other uses and also provides the additional functions listed below:

■ Backing up system programming information

■ Restoring system programming information from a backup

■ Converting system programming information from one release to another

(part of the upgrade procedure)

■ Upgrading your communications system to a newer release

■ Printing, viewing, and storing reports

■ Programming the communications system remotely

■ Programming in surrogate mode

SPM runs on a DOS-based PC as a stand alone program or on a UNIX

â

System platform as part of Integrated Solution II or Integrated Solution III (IS II/III). It is available on a 3.5-inch diskette for DOS or UNIX, or on a 5.25 inch diskette for

DOS.

NOTE:

SPM software can be used directly from the floppy disks on a DOS machine; however, if your PC has a hard disk, you should install SPM onto the hard disk.

This book describes the use of SPM on a PC with a DOS operating system. If your system has the IS II/III application, you have the UNIX System version of

SPM.
