Your Responsibility for Your System’s Security
Toll fraud is the unauthorized use of your telecommunications system by an unauthorized party, for example,
persons other than your company’s employees, agents, subcontractors, or persons working on your company’s behalf.
Note that there may be a risk of toll fraud associated with your telecommunications system, and if toll fraud occurs, it
can result in substantial additional charges for your telecommunications services.
You and your system manager are responsible for the security of your system, such as programming and
configuring your equipment to prevent unauthorized use. The system manager is also responsible for reading all
installation, instruction, and system administration documents provided with this product in order to fully understand the
features that can introduce risk of toll fraud and the steps that can be taken to reduce that risk. Lucent
Technologies does not warrant that this product is immune from or will prevent unauthorized use of common-carrier
telecommunication services or facilities accessed through or connected to it. Lucent Technologies will not be
responsible for any charges that result from such unauthorized use. For important information regarding your
system and toll fraud, see Appendix A, “Customer Support Information.”

About This Book
The MERLIN LEGEND Communications System is an advanced digital
switching system that integrates voice and data communications features. Voice
features include traditional telephone features, such as Transfer and Hold, and
advanced features, such as Group Coverage and Park. Data features allow
both voice and data to be transmitted over the same system wiring.
Intended Audience
This book provides detailed information about system and telephone trouble
reports and troubleshooting operations. It is intended for use by qualified field
technicians who are responsible for system maintenance and troubleshooting,
and as a reference by anyone needing such information, including support
personnel, sales representatives, and account executives.
How to Use This Book
This book provides step-by-step procedures for isolating troubles both inside
and outside the communications system. Refer to the chapter associated with
the reported problem to start the troubleshooting procedure.

■
Equipment and Operations Reference provides detailed information on
system hardware, telephones, and other equipment (not updated since
Release 3.0).
■
Feature Reference provides details on the features of the
communications system.
■
System Planning provides procedures and forms for planning a system
for installation.
■
System Programming gives procedural instructions for programming
system features.
■
Users’ guides and Operators’ Guides give procedural instructions for
programming and using telephone features.
“Related Documents,” later in this section, provides a complete list of system
documentation together with ordering information.
In this document, the terms in the following list are used in preference to other,
equally acceptable terms for describing communications systems.
Lines, Trunks and Facilities
Facility is a general term that designates a communications path between a
telephone system and the telephone company central office. Technically a trunk
connects a switch to a switch, for example the MERLIN LEGEND
Communications System to the central office. Technically, a line is a loop-start
facility or a communications path that does not connect two switches (for
example, an intercom line or a Centrex line). However, in actual usage, the
terms line and trunk are often applied interchangeably. In this book, we use
line/trunk and lines/trunks to refer to facilities in general. Specifically, we refer to
digital facilities. We also use terms such as personal line, ground-start trunk,
Direct Inward Dialing (DID) trunk, and so on. When you talk to your local
telephone company central office, ask them which terms they use for the
specific facilities they connect to your system.

Introduction
1
The purpose of maintenance is to detect, report, and clear problems quickly and
with minimal disruption of service. The system attempts to isolate each problem
to a single replaceable unit, whenever possible, by running automatic tests. In
private networked systems (Release 6.0 and later, Hybrid/PBX mode), many
problems are caused by programming errors rather than by malfunctioning
hardware. Errors that the system cannot automatically correct are usually
recorded in error logs. Most troubleshooting relies on checking the error logs
and interpreting them, using Table 2-6.
Equipment
To perform maintenance, you need a maintenance terminal and some additional
tools, all of which are defined below.
Maintenance Terminal
Whether you perform onsite or remote maintenance, you need a maintenance
terminal:
■
For onsite maintenance, you can use either an MLX-20L system
programming console or a PC with System Programming and
Maintenance (SPM) software.
■
For remote maintenance, you must use a PC with SPM software.

Page 1-2
Equipment
Detailed information about system programming is included in System
Programming and in System Programming and Maintenance (SPM).
You can use either a DOS PC or a Master Controller (MCII or MCIII) to run
SPM. To connect a PC to the control unit, you need a 355AF adapter and a
D8W-87 cord.
NOTES:
1. Onsite programming maintenance is preferred if it is feasible; remote
programming overrides onsite programming, except when onsite
backup or restore is in progress. See “On-Site Programming
Maintenance” on page 1–3 and “Remote Programming Maintenance”
on page 1–6 for details.
2. In Release 6.0 and later systems (Hybrid/PBX mode) where systems
are private networked and only one system has public switched
networked trunks, you must use the Remote Access feature in order to
access SPM on private networked systems. For details, see “Remote
Programming Maintenance” on page 1–6.
Tools and Documentation
In addition to the maintenance terminal, you need the following tools and
documentation:
■
Trouble report documentation
■
Troubleshooting guide
■
NSAC contact name
■
EIA breakout box
■
Digital voltmeter (KS-20599 or equivalent)
■
110/66-type punchdown tool

! CAUTION:
Should you ever need to open a module and handle the circuit board, use
the wrist strap to connect your wrist to a suitable ground first. Electrostatic
discharge can destroy or severely damage the integrated circuits in the
power supply, processor, and modules.
On-Site Programming Maintenance
You can perform onsite maintenance with an MLX-20L console or a PC with
SPM software. This book provides maintenance instructions from the console. If
you are using a PC, refer to System Programming and Maintenance (SPM) for
details. If you use the UNIX® System, see the documentation for Integrated
Solution Ill (IS III).
Setting Up the MLX-20L Console
To connect an MLX-20L console to the control unit, follow the steps below.
Refer to Figure 1–1 on page 1–5.
! Plug one end of a D8W-87 cord into one of the first five jacks on the
leftmost 008 MLX module or 408 GS/LS-MLX module.
The first MLX jack is the default. If it is already being used for the
attendant console, choose another jack. If one of the jacks is already
being used for system programming or maintenance, use that jack. Only
one jack at a time can be used for system programming or maintenance.
! Plug the other end of the D8W-87 cord into the LINE jack on the
underside of the MLX-20L console.

MLX-20L Failure
If the MLX-20L console does not work, follow the steps below.
! Replace the MLX-20L console with one that is known to be working
(if available).
! If the failure persists, or if a working MLX-20L console is not
available, connect the original MLX-20L console directly into the
appropriate MLX jack on the control unit using a cord that is known
to be working.
! If the trouble clears, replace the original D8W-87 cord.
If not, use the PC as your maintenance terminal and then troubleshoot
the leftmost MLX module. See “Module Problems” on page 4–34 for
instructions.

Remote Programming Maintenance
Remote maintenance allows you to support the system from an off-premises
location. You can check error logs and system status, execute a trace on one or
more facilities to verify call progression to isolate the source of a problem, and
restart the system remotely. Remote programming maintenance is particularly
useful for private networked switches (Release 6.0 and later systems,
Hybrid/PBX mode only).
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Remote Programming Maintenance
Issue 1
August 1998
Page 1-7
To perform remote maintenance, you need a PC with SPM software, a tip/ring
telephone, and a 1,200-bps modem. Beginning with Release 3.0, a 2,400-bps
modem may also be used.
Considerations
Review the following points before you begin remote maintenance procedures.
■
Remote maintenance overrides onsite maintenance and programming,
except when onsite backup or restore is in progress. Before you perform
remote maintenance, notify the customer’s system manager.
■
You can perform remote maintenance and programming only from a
DOS PC, not from the UNIX environment. If you are running SPM under
IS III, you cannot perform remote maintenance.
■
Line noise can cause the SPM screen to display unpredictable results. If
this occurs, hang up and redial.
NOTE:
Under applicable tariffs, the customer is responsible for any charges
incurred through the remote use of system facilities. Precautions should
be taken to prevent unauthorized use of the system’s outside lines by
remote callers, also called toll fraud. See Appendix A, “Customer Support
Information,” for more information about security.
Setting Up Equipment for Remote
Maintenance
To set up equipment for remote maintenance, follow the steps below while
referring to Figure 1–3 and to Installation.
! Connect the PC and modem.
■
If you have an external modem, use an EIA-232-D cable.
■
If you have an internal modem, the connection is already
established.

With a Local or Remote Modem Connection
When the equipment is set up, you can perform remote maintenance by dialing
the remote processor’s built-in 2,400/1,200-bps modem using Remote Access.
You can dial the modem directly or call the system operator and request to be
transferred to the modem. In Release 6.0 and later systems (Hybrid/PBX mode)
where systems are private networked and only one system has public switched
networked trunks, you must use the Remote Access feature in order to access
the system with public switched networked trunks and from that system reach
any switches connected to it directly or indirectly via tandem trunks. All three
procedures are explained below.

customer’s system. To dial the operator, follow the steps below.
! Start SPM. When the Welcome message appears, press any key.
! Enter the command to put the modem in originate mode (this
command varies depending on the type of modem you are using).
! Pick up the handset on the T/R telephone and dial the customer’s
system operator (the Listed Directory Number for the customer’s
system).
! When the attendant answers the call, explain what you are doing
and ask for any passwords you may need; then ask the operator to
transfer you to the modem by pressing the Transfer button and then
dialing .
NOTES:
1. If the password is not known, check the System Information
Report or ask to speak with the system manager.
2. You can change the password without knowing the old
password only when you perform onsite maintenance through
the ADMIN jack.

Maintenance Strategy

Page 1-21
Maintenance Strategy
The maintenance strategy presented in this section is only a guideline, not a
fixed procedure. Refer to Figure 1–7 on page 1–22 whenever you are uncertain
about how to proceed. It provides guidelines for analyzing problems in
non-networked systems.
For private networked systems (Release 6.0 and later, Hybrid/PBX mode), call
completion problems are usually caused by incorrect programming, although
alarms and error logs should be checked initially. The source of the trouble may
be the originating system or any system over which the call is conveyed. Fault
isolation is required to identify one or more misprogrammed switches, because
the problem may not originate at the system where it is reported. For this
reason, technicians should attempt to log into each private networked system,
preferably simultaneously, and originate test calls with traces to verify the
messages, states, and activities associated with the facilities and switches. If
the problem is indeed incorrect programming, a technician can correct it
remotely without going to the customers’ site(s). If test calling does not reveal

By system alarms (permanent errors)
Automatic Tests
The system performs ongoing maintenance automatically by running tests that
do the following:
■
Monitor the status of equipment
■
Audit operations consistency
■
Detect hardware malfunctions
Without disrupting normal service, the tests check hardware and software that
are in service. The system registers any errors it detects in the error logs and, if
possible, corrects them automatically.
Alarms
If the automatic tests indicate serious error conditions, the system generates an
alarm. Depending on how the system is programmed, the system announces an
alarm condition in one of the following ways:
■
An LED for a line or feature button turns on at an operator console or
other designated telephone.
■
The red status LED on the processor module lights.
■
In Release 3.0 and later, the error code/status display on the processor
module displays ) if a frigid start, or & if a cold start, occurs. See
“System Restarts” on page 1–24 for details about frigid start (System
Erase) or cold start (Restart).
If a software installation or upgrade is taking place, a blinking character
is displayed to indicate the status of the procedure. See “Forced
Installation/Upgrade of System Software” on page 4–19 for more
information.
■
The status display indicates an alarm (on an MLX-20L console or a PC
running SPM), and can be viewed on the Error screen.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Maintenance Strategy
■
Issue 1
August 1998
Page 1-24
A supplemental alert, bell, chime, or strobe, if installed, is activated.
If an LED is programmed to indicate the alarm, the LED stays lit until the error is
cleared.
When the system indicates an alarm, check the permanent error log screen.
Clearing Alarms
The system clears alarms automatically when the error condition no longer
exists.
To clear an alarm manually, select Drop on the MLX-20L console or 7+ on
a PC while viewing the error. See “Error Logs” on page 2–1 for more
information.
System Restarts
Depending on the severity and duration of a problem, you may need to restart
the system manually. Some errors cause the system to restart automatically.
Every restart causes an error log entry, and each type of restart has its own
error code. A cold start (Restart) or frigid start (System Erase) also causes a &
or ) to appear on the error code/status display on the processor module.
There are three types of system restarts, all of which occur automatically:
■
Warm start (you cannot select this from the Maintenance menu)
■
Cold start (select 5HVWDUW to do this manually)
■
Frigid start (select 6\VWHP(UDVH to do this manually)
Warm Start
A loss of power for less than 250 ms can cause a warm start. If this occurs, calls
in progress are not dropped, but calls in the process of being connected may be
dropped.

Page 1-25
Maintenance Strategy
Considerations
Power interruptions of less than 100 ms usually do not affect the system.
Warm starts may cause telephones without incoming calls to ring.
Cold Start (Restart)
If you need to restart the system, cold start (Restart) is recommended. Restart
drops all calls but saves system programming.
NOTE:
Non-network systems continually update in the event of a cold start.
To perform a cold start, select 5HVWDUW as follows:
Console Procedure
PC Procedure
Menu:6\V3URJUDP→([LW→6\VWHP→<HV
→→→→
Considerations
A cold start (Restart) occurs automatically after a power interruption of more
than one second.
A cold start (Restart) does not blank out the screen on an MLX-20L telephone
until the cold start is completed.
A cold start (Restart) can cause extensions with the Extension Status feature to
lose their toll restrictions.
For Release 6.1 and later systems, a cold start is performed to refresh the
Message Waiting lights on a local system and on all remote MERLIN LEGEND
systems that use the local system’s Voice Messaging System. If, after a cold
start, any Message Waiting lights on any of the systems are not refreshed,
perform a manual update. See ‘‘Centralized Voice Messaging’’ on page 1-31,
for more information.

Frigid Start (System Erase)
! CAUTION:
All system programming is erased. When you perform a frigid start
(System Erase), all calls are dropped, and the system configuration
information is erased. All system memory must be reinitialized, including
system programming. Then the entire system must be rebooted.
To perform a frigid start, select 6\VWHP(UDVH as follows:

Private Network problems (Release 6.0 and later, Hybrid/PBX mode)
NOTES:
1. If you change the jack assignment of any telephone, be sure to record
the extension jack change on Form 2a, System Numbering: Extension
Jacks. See Appendix B, “System Numbering Forms,” for details.
2. Private Network problems (Release 6.0 and later, Hybrid/PBX mode)
are generally caused by incorrect programming. When attempting to
isolate a private network problem following the guidelines here, see
“Network Calling Problems” on page 5–40.
Check Telephone Problems
If a customer reports telephone problems, use the following steps as a guideline
for determining the possible cause. Chapter 3, “Telephone Problems,”
discusses telephone problems in more detail.
! Discuss the problem with the user who reported the problem.
! Run the appropriate test to verify the complaint.
! Replace the telephone with one that works properly.
! If the problem persists, go to the next section, “Check the Error
Logs.”
! If the problem persists, replace the telephone wiring.
Check the Error Logs
If a system alarm turns on (see the top-right area of Figure 1–7 on page 1–22),
begin troubleshooting by checking the permanent errors in the error logs.
Use the following steps as a guideline to check the error logs. For more
information about performing the procedures, see “Checking the Error Logs” on
page 2–2. Also, when you check the error logs, you should refer to Table 2–2,
page 2–7 for a detailed description of each problem.
MERLIN LEGEND Communications System Release 6.1

Page 1-28
! Check the permanent errors.
! If errors still exist, check the transient errors.
! Check the last 99 errors whenever you want to review the 99 most
recently recorded errors—either permanent or transient.
NOTE:
In releases prior to 4.0, the error log displays only the last 10
messages.
Trouble Accessing the Error Logs
If you cannot access the error logs, or if the system is inoperable, use the
following steps as a guideline to troubleshoot the system.
! Check the power supply LED.
a. Is the power switch turned on?
b. Is the power cord connected to an AC wall outlet that is not
controlled by a wall switch?
If the LED is off and you are sure that the power is connected and
turned on, see “Power Supply Problems” on page 4–2.
! If you still cannot access the error logs after checking the power
supply, see “Processor Problems” on page 4–12.
! If you still cannot access the error logs after checking the
processor, see “Carrier Problems” on page 4–126.
! If you still cannot access the error logs, review “System Inventory”
on page 2–26 and escalate the problem to your technical support
organization.
Check the Access Log
At any time during the maintenance process, you can check the access log for
maintenance and system programming. This log indicates the last 20 times that
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Maintenance Strategy
Issue 1
August 1998
Page 1-29
someone accessed maintenance or system programming. If you find that
someone accessed maintenance or system programming shortly before the
problem originated, that person may be able to help you isolate the trouble by
providing additional information about what was done.
Once you receive that information, use any maintenance or system
programming feature that may lead to the root of the problem. See “Access Log”
on page 2–24 for additional information. See System Programming for
information about system programming and the Inspect function.
Check the Power Supply
If the error logs indicate the power supply as the source of the problem, see
“Power Supply Problems” on page 4–2.
Check the Processor
If the error logs indicate the processor as the source of the problem, use the
following as a guideline to check the processor.
■
Back up system programming.
— System programming can be backed up to a floppy disk, using
SPM.
— For Release 3.0 and later, system programming can be backed
up to a memory card, using SPM or the MLX-20L console. See
Appendix D, “Backing Up with a Memory Card,” for more
information.
■
See “Processor Problems” on page 4–12 to troubleshoot the processor.
Check the Modules
If the error logs indicate any modules, see “Module Problems” on page 4–34.

Check the Control Unit Carrier
Within the control unit, the last possible cause of a problem is the carrier. If the
carrier is damaged, it must be replaced. See “Carrier Problems” on page 4–126
for instructions.
Check the Trunks
Troubleshoot the trunks that are connected to the control unit. See Chapter 5,
“Central Office and Network Problems.”
Check the Central Office
If the error logs indicate the central office (CO) as the source of the problem,
and you have resolved all other possible causes, notify the customer that they
should call the central office and ask the central office to check the problem at
their end (see Chapter 5, “Central Office and Network Problems”):
■
If the problem is in the central office, wait for the CO to fix it. Then
duplicate the problem conditions to ensure that the problem is really
fixed.
■
If the problem persists, get the customer to again call the central office
with the problem.
■
If they indicate that the problem is not in the central office, escalate the
problem as described below.
Escalating the Problem
Escalate any unresolved problems to your technical support organization.
See “System Inventory” on page 2–26, which explains how to access the
System Inventory screen. This screen contains information (such as the
hardware vintage, software vintage, and ROM ID for each module) that your
technical support organization may request.

Centralized Voice Messaging
For Release 6.1 and later systems, Centralized Voice Messaging (CVM)
enables usage of a single voice messaging system by other directly connected
systems in a private network. When the Message Waiting lights on the local
system and on all remote MERLIN LEGEND systems that use the local
system’s Voice Messaging System may need to be updated. The lights are
updated manually by using the maintenance screens. Follow the procedures in
“Updating the Message Waiting Lights”.
For more information about Restart, see “Processor Problems” on page 4–12.
For more information about the Restart procedure, see System Programming.
Updating the Message Waiting Lights
NOTE:
These procedures are used only for Release 6.1 or later systems.
Non-networked systems continually and automatically update in the
event of a cold start.
Consider a manual update of the Message Waiting lights if:
■
a processor is changed
■
a VMS is changed on the hub system
■
a cold start did not successfully refresh
■
any other instance it is deemed necessary by a qualified technician
You must clear all the Message Waiting lights on the local MERLIN LEGEND
system, and then refresh the Message Waiting lights on extensions that use a
specific VMS, including telephones on a private networked MERLIN LEGEND
system (see the Network Reference for more information). Follow these general
steps below to update these lights.
! Clear the Message Waiting lights for systems reporting trouble with
lamp state.

Unit Loads
A unit load is a measure of power (1.9 watts) used to determine the electrical
load that the following components have on each carrier’s power supply:
■
Telephones and adjuncts
■
Direct-Inward Dial (DID) modules
Only the telephones and adjuncts that connect to the analog and digital ports on
the control unit require unit load calculation. Do not include any equipment with
its own power supply (for example, an answering machine) in the unit load
calculation.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Issue 1
August 1998
Page 1-36
Unit Loads
Checking Unit Loads
In the event of maintenance or equipment changes, recalculate the unit loads
for each carrier where there is a different configuration. Use the worksheet in
Appendix C, “Unit Load Calculation Worksheet.”
Generally, if you can distribute the DID modules and telephone modules equally
across the carriers, you prevent unnecessary drain on any one carrier.
The rules vary, however, depending on the system’s mode. The next two
sections provide the rules for calculating unit loads in various modes.
Unit Loads for Hybrid/PBX Mode
The power supply (model 391A1) generally supports six modules of any type in
a Hybrid/PBX system. However, if both of the following conditions are true, the
unit loads on a carrier can exceed the 54-unit (102.6-watts) maximum:
■
All six carrier slots are occupied by MLX telephone or analog multiline
telephone modules.
■
The carrier has more than 45 MLX-20L telephones and/or 34-button
analog multiline telephones installed.
Unit Loads for Key or Behind Switch Mode
In a Key or Behind Switch system with four or fewer modules, no calculation is
needed. The power supply (model 391A1) generally supports four modules of
any type in Key or Behind Switch mode.
Upgrading the Power Supply
The 391C1 or 391A3 power supply has a maximum rating of 75 unit loads. If
your system contains a 391A1 or 391A2 power supply module, and the unit
loads for that carrier will exceed 54, it is recommended that a 391A3 power
supply or later be installed in the system. Auxiliary Power Units are no longer
necessary.

Unit Loads
Issue 1
August 1998
Page 1-37
! CAUTION:
Running the system with more than 54 unit loads (102.6 watts) per carrier
may not appear to do harm. However, this can cause the system to
malfunction, creating “No Trouble Found” conditions.
If a new power supply is required, complete installation instructions are
provided in Installation.

As described in ‘‘Maintenance Strategy’’ on page 1-21, much of your
troubleshooting relies on the error logs and the access log, for maintenance and
system programming. Both of these maintenance features are described here in
detail. This chapter also explains how to access the System Inventory screen,
which you may need when you escalate problems to your technical support
organization.
For information about entering and exiting maintenance functions on a console
or a PC running SPM, see Chapter 1, “Introduction.”
Error Logs
When an error occurs, the system records it in the error logs, which are stored
in battery backed-up RAM. These errors indicate problems that span the entire
system, including the control unit, telephones, adjuncts, and network interface.
Transient errors are less serious than permanent errors. However, some
transient errors can become permanent if they occur a certain number of times,

Once you isolate a problem to the telephone (or a group of telephones), you can
run various tests to check a telephone’s operation.
Use the procedure below as a general guideline for troubleshooting telephones.
! Replace the telephone (or adjunct) with one that works properly.
! If the problem persists, connect the telephone directly to the
control unit, using a cord that works properly.
■
If this solves the problem, replace the original cord.
■
The power supply may be shorted or open. If the wiring has been
crushed or severed, replace it.
a. Test the power supply for 48 VDC with a voltmeter or by
reconnecting the telephone or adjunct.
b. If the test for 48 VDC fails, replace the circuit pack in the
telephone or adjunct.
! CAUTION:
A faulty circuit pack has the potential to damage the power supply,
which can cause widespread damage throughout the system.
! If the problem persists, replace the mounting cord.
! If the problem continues, proceed as described in the next sections.

General Telephone and Wiring Problems
If intermittent telephone trouble occurs, use the following steps as a guideline to
check for general telephone and wiring troubles.
NOTE:
Refer to “Troubleshooting Trunk Problems” on page 5–1 if the reported
problem is echo during conversations on T1 trunks with GS emulation
connected to a toll office.
! Check modular connections in the telephone for loose or broken
connectors.
! Check modular connections in the connecting blocks for loose or
broken connectors.
! Check modular connections in the control unit for loose or broken
connectors.
! Check transient errors in the error logs for any possible clues.
! If local power is provided, check the power supply connectors and
voltages.
! Replace the telephone with a telephone that works to determine
whether the problem is the telephone itself.
! If trouble disappears, replace the problem telephone.
! If the replacement telephone does not work properly, check the
other telephones connected to the same module.
■
If these telephones work, the problem may be the wiring, or there
may be a single-port failure on the module. To check the wiring,
go to Step 12.
■
If these telephones do not work, the fault is probably in the
module. To check the module, go to Step 9.
! Check the LEDs on the module.
If the module does not have LEDs, see “System Status” on page 4–128
for more information.
! Check the error log for relevant messages.
See “Error Logs” on page 2–1.

! Replace the faulty module.
! Replace the wiring between the module jack field and the telephone
to see if there is a wiring problem.
Analog Multiline Telephone Problems
If telephone LEDs and/or ringing tones do not work properly on analog multiline
telephones, follow the steps below.
! Move the T/P switch on the left-hand side to the T (test) position.
You should hear tone ringing, and the red and green LEDs on the
terminal should flash alternately.
! If the LEDs do not light, replace the telephone with one that works.
If the problem is resolved, go to Step 4.
! If the LEDs do not light, retest the original telephone.
Plug it directly into the appropriate jack on the control unit, using a cord
that is known to be working.
If this resolves the problem, replace the original cord (or local power unit,
if used).
! Move the T/P switch to its normal position.
The ringing tone should stop, and the LEDs should be off.
! If any part of the test fails, replace the telephone.
If the time appears on the display but incoming call information does not,
move the T/P switch on the side of the telephone to the center position.
Voice Transmission Problems
If the telephone does not receive tones, check the control unit and wiring with a
telephone that works.

Single-Line Telephone Problems
If more than one single-line telephone cannot dial correctly, even though they
are receiving calls, use the steps below to test the touch-tone receivers (TTRs)
for a single-line telephone.
! Pick up the handset; then dial and the 2-digit number of the TTR
you want to test.
■
If you hear a busy tone, the receiver is in use/off hook.
■
If you hear a reorder tone, you have misdialed or have reached
an invalid TTR. Try again.
■
If you hear a dial tone, go to Step 2.
! Dial .
You should hear a dual-tone multi-frequency (DTMF) signal as you press
each button. If the test is successful, you hear a three-beep confirmation
tone one to three seconds after you press #.
! Hang up and repeat Steps 1 and 2 for each TTR.
! If this test fails, replace the module containing the faulty TTR.
If all TTRs fail this test, repeat the test, using a different telephone that
works. If the tests are successful, replace the original telephone.
If users cannot make outside calls on a touch-tone telephone, check the
individual trunk for rotary-dial programming. See System Programming
for details.

System Requirements for
Touch-Tone Receivers
A voice messaging system requires a certain number of TTRs in addition to any
system requirements for TTRs. The number of TTRs depends on the number of
ports used by the voice messaging system (see Table 3–3). TTRs are also
required in private networks using E&M, T1 tie, and tandem tie trunks.
In Release 6.0 and later systems, the use of the Prompt-Based Overflow
setting, which allows callers to request overflow coverage while waiting in a

System Requirements for Touch-Tone Receivers
Table 3–4 estimates the total number of TTRs required in the system, based on
call volume and whether the system uses account codes. The call volume per
hour in this table includes all calls originating from single-line telephones, calls
on tie lines, incoming remote access and DID calls.
NOTE:
You must consider the call traffic across a private network when
estimating the number of required TTRs. This includes calls on analog
tandem tie trunks and T1-emulated tandem tie trunks. In addition, if your
private network includes Centralized Voice Messaging, you must
consider the call traffic coming across the private network for the voice
messaging system and the TTRs required for the updating of Message
Waiting lights (Release 6.1 or later systems). For this updating, a TTR is
required at the sending end and the receiving end. If the systems in the
private network are connected by PRI trunks, no additional TTRs are
needed.

! Estimate the hourly call volume for calls originating from single-line
telephones, incoming calls (including private network tandem tie
trunks) on remote access and Direct Inward Dial (DID) lines, all calls
on tie lines, and calls routed to the voice messaging system.
NOTE:
You must consider the call traffic across a private network when
estimating the number of required TTRs. This includes calls on
analog tandem tie trunks and T1-emulated tandem tie trunks. In
addition, if your private network includes Centralized Voice
Messaging, you must consider the call traffic coming across the
private network for the voice messaging system and the TTRs
required for the updating of Message Waiting lights (Release 6.1
or later systems). For this updating, a TTR is required at the
sending end and the receiving end. If the systems in the private
network are connected by PRI trunks, no additional TTRs are
needed.
! Use Table 3–4 to determine the number of TTRs required by the
system.
■
Use Column 2 if account codes are not being used.
■
Use Column 3 if account codes are being used.
! Add the number of TTRs obtained in Steps 1 and 3. If the Group
Calling Prompt-Based Overflow setting (Release 6.0 and later
systems) is not being used, go to Step 6.
! If the Group Calling Prompt-Based Overflow setting is being used
by calling groups, first add the number of TTRs needed for the
primary delay announcement devices assigned to those calling
groups, according to Table 3–5. Then add the number of TTRs
needed for the secondary delay announcement devices assigned to
those calling groups, according to Table 3–6.
NOTE:
If no announcement is used on a primary or secondary delay
announcement device, no TTRs are needed.

Module Problems
If you suspect that a module is faulty, perform the following procedures:
■
To identify the cause of module errors, run the module tests described
below.
■
To determine whether the module is faulty, replace it with a module of the
same type. If the errors cease, the problem is solved.
Module Tests
The module tests in this section identify the cause of module malfunctions. After
each module test, record any errors on the repair tag that will be shipped with
the faulty module. If the module is sent for repair, this helps repair personnel
troubleshoot the cause of the malfunction.
You should read through the following section, “Module Test Process,” before
running any module tests.
NOTE:
A module on which you run tests cannot be used for service. Because
your customer depends on this service, run module tests during off
hours, if possible. If you cannot, minimize the time required for each
module’s downtime whenever possible.
Module Test Process
Figure 4-6 shows the module test process. Refer to it and the text that follows
for the recommended approach to testing modules.

NOTES:
1. If any problem arises with the voice call on an NI-BRI module, run the
NI-BRI Provisioning Test next. While the BRI test is running, you can
run the voice test on the next module.
2. Run the NI-BRI Provisioning Test on any NI-BRI module that is going to
be used for data calls or that had a problem with voice calls and was
not previously tested with the tool.
Considerations
Review the following items before you begin a module test procedure.
System Components
Before running a module test, make sure the following system components are
working:
■
Power supply
■
Processor. Save the system programming onto a floppy disk. See
System Programming and Maintenance (SPM). To back up onto a
memory card, see Appendix D, “Backing Up with a Memory Card.”
■
Maintenance Terminal (MLX-20L console or PC). To run tests on the MLX
module connected to the MLX-20L console, you must run the test from
the PC, not from the MLX-20L console.
Busy-Out/Reset
Before running a module test, busy-out or reset the modules. Busy-Out is the
best method, but it will not work if any line or extension is on a stable call. See
‘‘Busy-Out and Reset’’ on page 4-38 for more information about these features.
Test Notes
For each test, note the following points:
■
When beginning the board controller test or the internal loopback
module test, choose to run it once or repetitively.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Issue 1
August 1998
Page 4-37
Module Problems
■
You can interrupt any module test by selecting Exit ( on the PC).
■
A module test can fail for one of the following reasons:
— The module being tested was not busied-out. Exit the test,
busy-out the module, and try again.
— The error messages indicate that the module is faulty.
■
If errors indicate that the module is faulty, record them on the module
repair tag immediately after running the test.
NOTE:
If the system does not recognize a 408 GS/LS-MLX module during
testing, check the release number of the system. The 408
GS/LS-MLX module does not work with Releases 1.0 or 1.1. An
008 MLX module must be used to provide extension jacks with
Releases 1.0 or 1.1.
To run a module test, follow the steps below.
! To determine which modules are suspect, read the error logs and
review any user-reported problems.
! If the error logs indicate the processor is the problem, refer to
‘‘Processor Problems’’ on page 4-12 to service the processor
before continuing.
Replacing a faulty processor may resolve module problems.
! Busy-out or reset the module.
See ‘‘Busy-Out and Reset’’ on page 4-38 for general guidelines.
! Run the internal loopback test.
See “Internal Loopback Test” on page 4–47. If errors occur, record them
as described in ‘‘Considerations’’ on page 4-36.
! Run the board controller test.
See “Board Controller Test” on page 4–53. If errors occur, record them
as described in ‘‘Considerations’’ on page 4-36.

them as described in ‘‘Considerations’’ on page 4-36.
! For 800 NI-BRI modules, continue with the NI-1 BRI Provisioning
Test.
See “800 NI-BRI Module Problems” on page 4–75. If errors occur, record
them as described in ‘‘Considerations’’ on page 4-36.
! For 100D modules, continue with the CSU loopback test.
See “100D Module Problems” on page 4–100. If errors occur, record
them as described in ‘‘Considerations’’ on page 4-36.
! Replace the module with a module of the same type, whether you
are troubleshooting or replacing the module permanently.
! Restore the module.
Menu: 0DLQWHQDQFH→6ORW→Dial the slot no.→5HVWRUH→<HV
Restoring automatically undoes the busy-out and reset. For additional
information about restoring a module, see ‘‘Restore’’ on page 4-45.
Persistent Module Problems
If any of the module tests fail and replacing the module does not clear the
trouble, then either several modules may be faulty or the connector on the
carrier may be faulty.
Busy-Out and Reset
Before running any module test, be sure to busy-out or reset the module.
■
Busy-out discontinues service from the module being tested to each line
and extension only as they become idle. Busy-out is the preferred
method, because it does not disrupt calls in progress.
■
Reset discontinues service to all lines and extensions on the module
instantly.

— In-progress calls are dropped if all of the calling parties on the
call originate and terminate on the module being reset.
— If a call is using a line or extension on the module being Reset
and another line and/or extension is involved in the call, the call
on the module being reset is put on hold. In this case, the module
can be removed and replaced. However, a demand test cannot
be performed, because the module is not busied-out.
■
Check the status of the reset module before performing a demand test.

It takes approximately 1.5 minutes to run each test. The
100D module and 408 GS/LS-MLX module each take
approximately 3 minutes, because they each have two
DSEs.
Busy-Out or Reset
Busy-out or reset the module being tested prior to
beginning the test. Both Busy-Out and Reset are in the
Slot menu, which you can access by doing the following
from the console:
Menu: 0DLQWHQDQFH→6ORW
See ‘‘Busy-Out and Reset’’ on page 4-38 for additional
information.
Interrupting the Test
You can interrupt the test (both 7HVW2QFH and
5HSHWLWLYH) by selecting ([LW.
Test Failure
If the test fails, record the errors on the repair tag and
replace the module.
Restore
Restore the module if it successfully completes all
module tests and the errors no longer occur. Restore is
in the Slot menu, which you can access by doing the
following from the console:
Menu: 0DLQWHQDQFH→6ORW

Replacing Modules
You can remove and insert line/trunk and extension modules (separately or at
the same time) with the system power on without affecting normal call
processing.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Issue 1

Module Problems
Page 4-62
! CAUTION:
This section does not apply to the processor or power supply.
Although the system is designed so that you can remove and replace
modules without affecting call processing, partially inserting and removing
a module can cause a cold start.
Adding a 100D module or changing any of its DS1 parameters requires
that the system be idle.
When you replace a module, be sure to use the same module type. For
example, do not put an 008 MLX module in place of a 400 GS/LS module.
If a module is replaced with another type of module, or if a module is added
to the system without powering down the system first, a cold start occurs.
If you move any module to a different slot, be sure to renumber the
modules by selecting %RDUG5HQXPEHU from system programming. See
System Programming for information about board renumbering.
To replace a module, follow the steps below.
! Busy-out or reset the module. Busy-Out is recommended.
! Label all cords (if they are not labeled already) and then unplug
them from the module.
For information about labeling trunk and cords, see Chapter 4 in
Installation.
For instructions on checking poorly labeled wiring, see ‘‘Checking
Unlabeled Wiring’’ on page 4-63.
! Run a demand test by entering test mode.
! Remove the module by pushing up firmly on the tab at the bottom
rear of the module and inspect the module for visible damage.
! Insert the new module. While holding the tab, bring the bottom of
the module towards you and away from the carrier.
MERLIN LEGEND Communications System Release 6.1

Module Problems
Issue 1

Page 4-63
! Restore the module. Lift up the module to disengage it from the rod
at the top of the carrier.
! Connect the trunk and extension cords.
! Attach a tag, error printout, or any information that will help identify
any visible problems, failure symptoms, and relevant error reports.
Checking Unlabeled Wiring
If a label is missing or damaged, use a tone device and a telephone handset to
match like wires.
You need the following tools:
■
Tone device
■
Telephone handset
■
Telephone cord with an 8-pin modular plug
■
4-pair patch cord
■
Diagonal pliers or wire strippers
To match like wires, follow the steps below.
! Insert the telephone cord’s 8-pin plug into an outlet on the floor
area.
! Using diagonal pliers or wire strippers, cut off the end of the
telephone cord to expose the pairs.
! Choose a single pair and then untwist the wires.
! Attach to each clip one wire from the pair you have chosen. The
clips extend from the bottom of the tone device.
! Turn on the switch on the outside of the tone device.
You hear a high-pitched, alternating signal.

Module Problems
! Take the telephone handset and a 4-pair patch cord to the
cross-connect field between the control unit and the telephone.
! Go to the blue field on the cross-connect field and, starting at the
top left corner, push the patch cord onto the first connecting block.
! Using the diagonal pliers or wire strippers, cut off the other end of
the patch cord and expose the pairs.
Do not cut out too much of the cord, because you need the length to test
the top rows of the cross-connect field.
! Attach the handset’s clips, which extend from the base, to the
exposed wires of the patch cord.
! Set the switch on the side of the handset to MONITOR.
! Listen to the handset for the tone device signal.
■
If you hear the signal, you have found the correct wires. Correctly
label both the cross-connect field and the outlet.
■
If you do not hear the signal, remove the patch cord from the
connecting block and push the patch cord down onto the
connecting block to the right of the one just tested. Keep moving
the patch cord to the next connector block on the right until you
find the pairs that carry the tone device signal.
Upgrading Circuit Module Firmware
Beginning with Release 3.0, MERLIN LEGEND Communications System allows
upgrades or reinstallation of circuit module firmware through the PCMCIA
interface slot on the processor module. The interface slot is a standard interface
through which information may be added to or retrieved from the system.
Circuit modules introduced with Release 3.0 or later may use flash ROM to
retain circuit module firmware. Unlike traditional ROMs, flash ROM can be
written and erased without being removed from the circuit module. As of
Release 4.0, the circuit modules that include this feature are the 016 (T/R), the
800 GS/LS-ID, and the 800 NI-BRI.

800 NI-BRI Module Problems
An 800 NI-BRI module requires running the provisioning test, in addition to the
other module tests, under the following circumstances:
■
The module has data endpoints that use the BRI lines.
■
Voice Call manual testing of the module’s BRI lines indicates problems.
The test described in this document supports the NI-1 BRI IOC Package “S”
service configuration. Multiline-Hunt Group/Series Completion testing is
included here.
See Figure 4-6 for a diagram of the entire module testing process. If you have
any questions about the 800 NI-BRI module and do not find the answers here,
contact NSAC at 1 800 628-2888.

Maintenance and Troubleshooting 555-661-140
800 NI-BRI Module Problems

Page 4-76
NI-1 BRI Provisioning Test
This test verifies that each communication path on the 800 NI-BRI module is
operational by establishing and disconnecting a series of voice and data calls
between any two communication paths on the module.
In Release 4.1 and later systems, the NI-BRI Provisioning Test is enhanced to
include testing for BRI facilities that are part of Multiline Hunt Groups (MLHGs).
Prior to testing, the BRI facility must have a MLHG group number programmed.
The number (up to 10 digits) is appended to the end of the Directory Number
(DN) (separated by a # character) programmed for the BRI line.
Before proceeding with this test, obtain completed copies of System Planning
Form 3-i, Incoming Trunks: BRI Options and the NI-1 BRI Planner Form.
NOTE:
If an 800 NI-BRI module has only one DN/SPID provisioned on it, the
provisioning test cannot be run on that module. To test the line, move one
DSL from another 800 NI-BRI module to this module. The DSL that is
moved should have been tested successfully and, to make testing easier,
should not be part of a MLHG. This move involves administering a line on
the DSL and connecting the cable on the target module. Run the test on
the two DNs. When the test is successfully completed, remove the
programming from the board just tested so that the single line is left on
the board. Then reconnect the cable to the original slot and port.
Beginning with Release 4.1, all 800 NI-BRI modules must be busied out and
those BRI boards not being tested must be unplugged from the carrier before
testing can begin.

100D Module Problems
The 100D module requires the CSU Loopback Test, in addition to the other
module tests. See Figure 4-35 for a diagram of the entire module testing
process. If you have any questions about the 100D module that this section
does not cover, contact your technical support organization.
Private Networked Systems
The Channel Service Unit (CSU) or Data Service Unit (DSU) at either end of a
PRI tandem trunk over which a call could be routed, may be programmed for T1
or robbed-bit signaling rather than PRI signaling. This will cause the MERLIN
LEGEND to raise a channel inoperative alarm. Verify that any CSU on the DS1
circuit between the MERLIN LEGEND and the public switched telephone
network (PSTN) is programmed for the same framing as is the DS1 slot on the
MERLIN LEGEND. Also, verify that any CSU on the PRI circuit between the
MERLIN LEGEND and the PSTN is programmed for PRI signaling and not for
T1 or robbed-bit signaling.
NOTE:
If your existing MERLIN LEGEND Communications system is now
going to be used for a private network using tandem trunks, check
the framing to be sure PRI signaling is supported.

In preparation for running the CSU Loopback Test, perform the steps below at
the CSU.
! Busy-out the 100D module.
! Prepare the CSU.
For the 551 T1 CSU, connect the EQ OUT and EQ IN jacks (see Figure
4-8).
a. Plug one end of a bantam-to-bantam patch cord (or a loopback
fixture) into the EQ OUT jack on the front of the CSU.
b. Plug the other end of the patch cord into the EQ IN jack on the
CSU.
This causes the 551 T1 CSU to either loop back the private network signal or
send the all-ones pattern, depending on the chosen CSU option.
For the ESF T1 CSU, flip the DTE LOOPBACK switch on the front panel to the
up position to activate the loopback test (see Figure 4-9).
For the ACCULINK 3150 CSU, Press the F2 button on the front panel to select
7HVW from the menu screen. From the Test screen, press the F2 button to select
/SEN. From the Loopback screen, press the right arrow once to display
additional loopback tests. Press the F3 button to display '/% (DTE Loopback).
When '/% is selected, 7HVW6WDUWHG appears on line 2 of the menu screen.
(See Figures 4-10 through 4-13.)

Automatic Tests for the 100D Module
Every 15 minutes, the system checks the 100D module for the following:
■
Initialization. The system ensures that all T1 ports are properly initialized
and placed into service. It also resolves the conflicts of different service
levels (for example, between the individual ports or for the initialization
of the ports to support features).
■
Error Detection. The system detects errors and takes the trunk out of
service, if appropriate. It attempts to restore the trunk and put it back
into service.
■
Error Recording. The system records all errors and outages in the error
logs.
■
Audits and Updates. The system checks the state of the T1 facilities
through audits, status checks, and error logging.
■
Synchronization. The system maintains proper synchronization to the
loop clock and switches to the local clock when the loop clock is not
available (for example, during a loss of signal or a blue alarm). When the
loop clock source is restored, the system switches back to the loop
clock.

Computer Telephony Integration
(CTI) Link Problems
If you experience CTI link problems, you can perform the following maintenance
procedures:
■
Viewing Status. This procedure identifies whether the MERLIN LEGEND
Communications System recognizes that the link is physically
connected and operational.
■
Test. This procedure allows you to check whether the MERLIN LEGEND
Communications System and the PBX driver are communicating across
the link without involving the Telephony Services product. This is helpful
in isolating a problem to the Telephony Services product.
■
Restart. This procedure cleans up a link that is experiencing problems,
then reconnects the link and makes it operational again. Restart does
not shut down the link, but does affect traffic on that port.
■
Vary the Hiding Time. This procedure may be helpful if a link displays
problems. This should be done only at the request of a Tier 3 engineer.
NOTE:
Review the procedures in ‘‘Module Problems’’ on page 4-34 to determine
that the module into which you have plugged is not faulty.
Before you start maintenance or troubleshooting procedures for the CTI link,
verify the following:
■
The MERLIN LEGEND Communications System is operating in
Hybrid/PBX mode.
■
The CTI link is plugged into a port on an 008 MLX or a 408 MLX module.
■
The link is plugged into the RJ45 jack on the ISDN card in the Telephony
Server and the wire connection to the server is complete.
■
The firmware for the MLX module is of vintage earlier or later than 29.
Link administration is prevented on modules using firmware 29.

Varying Hiding Time
! CAUTION:
This procedure should be done only under the direction of NSAC/Tier 3
engineers. It is not recommended for users or service technicians. If this
value is changed, a corresponding change must be made for the PBX
driver under the direction of Technical Support Organization (TSO)
personnel.
Hiding time is the amount of time (in seconds) that the link could be broken but
users would not notice. This interval occurs when the link experiences a hidden
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140

Page 4-123
reset until the system generates a broadcast reset. A broadcast reset affects
CTI link operations and reinitializes the link. The factory setting for hiding time is
25 seconds, with a range of settings from 0 to 90 seconds.
Varying the hiding time may be helpful if the link displays problems. If broadcast
resets would help identify when a CTI link problem occurs, reduce the hiding
time to 10. This broadcasts all link troubles that cause resets. If broadcast
resets inhibit troubleshooting a CTI link problem, increase the hiding time. If the
broadcast reset messages still interfere with troubleshooting the problem, set
the hiding time to zero(0). Setting the value to zero eliminates all broadcast
resets; everything is hidden.

Removing a CTI Link
The following two procedures are used for CTI link removal:
■
Permanent Removal. When you want to permanently remove a CTI link
from the MERLIN LEGEND Communications System.
■
Link Shutdown. When you want to temporarily idle a CTI link before
working on it.
Permanent Removal
For a permanent CTI link removal, perform the following steps:
! (optional) Suspend MERLIN LEGEND alarming for the CTI link.
Refer to the System Manager’s Guide for the steps to suspend the
alarming. If Step 1 is not performed, the system may generate an alarm
about the CTI link before Step 5 is performed.
! Upload the PBX Driver (MLPD).
Refer to the System Manager’s Guide for instructions.
! Unplug the CTI link.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Removing a CTI Link
Issue 1
August 1998
Page 4-126
! Remove the ISDN link interface card, if desired.
Refer to the PC/ISDN Platform Installation and Reference, or similar
installation manual from the ISDN link interface card vendor.
! Remove the MERLIN LEGEND administration.
Delete the MLX port from the list of CTI link ports, using MERLIN
LEGEND system programming (at the MLX-20L or SPM). After this, it is
safe to plug in an MLX telephone, a data module, or an ISDN terminal
adapter. See System Programming.
Link Shutdown
Temporarily idling a CTI link before performing maintenance is an optional
procedure on the server side; it can prevent unwanted MERLIN LEGEND
Communications System alarms. However, a link shutdown is not required
before performing maintenance.
For a link shutdown, perform the following steps:
! Suspend MERLIN LEGEND alarming for the CTI link.
If Step 1 of the link shutdown is not performed, then the MERLIN
LEGEND may generate alarms about the CTI link while under
maintenance. See the MERLIN LEGEND System Manager’s Guide for
detailed instructions on this procedure.
! Prevent new CTI link traffic.
If Step 2 is not performed before working on the CTI link, an application
may get confused. For example, if an application sent a service request
(such as Make Call) but the CTI link is taken down for maintenance
before the MERLIN LEGEND sends a reply, the application will think the
request failed even if it succeeded. In contrast, if this step is performed,
the application will immediately receive a failure reply. See the MERLIN
LEGEND Network Manager’s Guide for detailed instructions on the
Block, Offline, and mloam commands.
! Wait for CTI link traffic to subside.
MERLIN LEGEND Communications System Release 6.1

Issue 1
August 1998
Carrier Problems
Page 4-127
If the Offline or mloam command was used in Step 2, skip to Step 4.This
step applies only if the Block command was used in Step 2.
Determine when traffic has stopped. On the NetWare server, start the
mloam or wmloam tool, then go to the Link Status screen. View the line
&7,/LQN0VJ5DWH. If the value shown is 0, then traffic on the link has
stopped. Refer to the System Manager’s Guide for details.
! Unplug the CTI link or perform appropriate maintenance.
Carrier Problems
Typical carrier problems include power supply failure, sudden failure of one or
more modules, or system problems that cannot be isolated to a specific module.
If you find a problem with the carrier, it must be replaced; carriers cannot be
repaired in the field.
Removing the Faulty Carrier
! Remove the control unit housing.
If you need instructions, see “Removing the Control Unit Housing” on
page 1–18.
! Back up system programming.
If you need instructions, see System Programming and Maintenance
(SPM) (for disk backups) or Appendix D, “Backing Up with a Memory
Card.”
! Power down the system by turning off the components listed below,
in the order given.
a. Power supply on the basic carrier
b. Power supply on each expansion carrier
c. Auxiliary power units (if present)
! Unplug the control unit from the AC outlet.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140

Page 4-128
! Remove the processor, the power supply, and all other modules
from the faulty carrier. (If you prefer to remove the cords first, make
sure that they are labeled.)
! Put the modules aside, in order, so that you can reinstall them later
in the replacement carrier.
! Remove all modules from the carriers to the right of the faulty
carrier.
! Starting with the rightmost carrier, loosen the four screws that
secure the four corners of the carrier to the backboard.
! Slide the carrier to the right until the connector disengages from the
carrier to the left.
! Pull the carrier away from the wall so that the screws slip through
the large screw holes.
! Repeat Steps 8–10 until the faulty carrier is removed.
Replacing the Carrier
After removing the faulty carrier, use the steps below as a guideline for installing
a new carrier.
! Install the replacement carrier(s). See Installation for instructions.
! Replace the modules with all cords connected as they were before.
Checking System and Slot Status
In addition to checking error logs, and the access log, and running module tests,
you can request System Status and Slot Status information for each module.

The System Status screen simulates LEDs for each module. The simulated
LEDs are represented as R (red), Y (yellow), and G (green).
Immediately following 5, <, or * is its status (BBB in the screens shown above),
which can be On, Off, or No status (an empty slot in the control unit).
Red LED
When the red LED is on, the module is not in service because it is in standby
mode, being tested, or is in an alarm condition. When a module resumes normal
operations, the red LED turns off.
Yellow LED
When the yellow LED is on, it usually means that at least one call is in progress
on that module. This is usually true for modules with trunks. When this is the
status, you must reset the board if you want to terminate any calls in progress
rather than waiting for them to terminate during a Busy-Out.
Green LED
The green LED is usually off. It may be on during power up or when an Internal
Loopback or CSU Loopback Test is running.
Sample LED Display (Slot 4)
If a call is in progress on a module that is in a working or normal state, the
System Status display for that module appears as:

If you have tested the telephones and the modules in the control unit, you have
isolated the trouble to the trunks or the CO. To isolate the trouble further, follow
the instructions in this chapter to troubleshoot the trunks. If the trouble persists
after following these instructions, the customer should contact the CO and ask a
representative to troubleshoot from that end.
Trunk Errors
The system records errors not only for trunks, but for T1 ports on the module as
well. In some cases, errors occur not because a single port fails, but because
the entire T1 link fails. When this happens, 100D automatic testing activates an
alarm.
Troubleshooting Trunk Problems
Table 5–1 provides a quick guide to troubleshooting trunks.
NOTE:
If the customer reports echoes during conversations on T1 trunks with GS
emulation to a toll office, check the system programming for T1 trunks.
The system is not intended to work with GS emulation to a toll office. Tie
trunk emulation must be programmed. Program the module to emulate tie
trunks to the central office.

Manual Correction of Trunk Problems
If the system cannot seize a trunk even after repeated attempts, you may have
to replace the module.
To identify the trunk problem, follow the steps below.
! Check for dial tone at the control unit.
! If you do not hear dial tone, check the error logs and make a trunk
test call.
! Check for dial tone at the network interface.
It is sometimes difficult for the customer to detect trunk troubles. If a trunk
is down, the system records an error in the error log and takes the trunk
out of service. However, if an incoming-only trunk is down, the only sign
of trouble is customer complaints that incoming calls are not being
received.
Check the error logs for messages about trunk type (such as DID, tie,
and T1). Also check the wiring and the system parameters (for example,
touch-tone/rotary, toll restriction, and disconnect time interval).

Trunk Errors
Outgoing Trunk Problems
If the system cannot seize outgoing trunks, try the following procedure for
analog lines.
NOTE:
You cannot perform this procedure on a rotary telephone.
! Check for outside dial tone at the network interface.
For GS trunks, apply ground to the ring lead to get dial tone. If dial tone is
not present, notify the customer.
NOTE:
Steps 2 through 4 only apply to Hybrid/PBX mode. Go to Step 5 for
systems in Key or Behind Switch mode.
! Pick up the handset of a test telephone to check for system dial
tone.
Dial, then dial the maintenance password.
1. If the password is not known, check the System Information
Report or ask to speak with the system manager.
2. You can change the password without knowing the old password
only when you perform on-site maintenance through the ADMIN
jack.
! Dial the 2-digit trunk number (01–80) of the trunk you want to test.
! Listen for dial tone.
■
If dial tone is not present, use a test telephone to isolate the
problems either to the module where the trunk terminates or to
the location in the trunk access equipment.
■
If dial tone is present, dial a working outside number to verify that
the call can be completed.
— Dialing an outside number on a single-line telephone
works only if the trunk accepts touch-tone dialing.

Trunk Errors
— If you are using a single-line telephone to dial out to an
E&M tie trunk or a T1 tie trunk, wait for a click before
dialing the outside number.
If the trunk is busy, you hear a busy tone. If you dial a
wrong trunk type (such as DID) or an invalid trunk number,
you hear a reorder tone.
! If the module continues to malfunction, replace it.
Incoming Trunk Problems
If incoming trunks do not work properly, try the following procedure.
! Place an incoming call through the troubled trunk.
■
For a loop-start (LS) trunk, connect a single-line telephone to the
trunk at the network interface.
■
For a ground-start (GS) trunk, connect a single-line telephone to
the trunk at the network interface and press the GS button. (For
GS trunks, the telephone must have a GS button attached to it.)
! Listen for ringing.
! Pick up the handset and check line seizure.
! Dial an outside number and verify that you have good two-way
transmission.
! At the maintenance terminal, check the trunk programming to be
sure this trunk has been properly translated.
See the system planning forms.
! If the module continues to malfunction, replace it.

Testing Trunks Automatically
The automatic maintenance program takes the ports out of service when a trunk
is malfunctioning. When a port is out of service, it is maintenance-busy. The
trunk is periodically tested and put back into service if possible.
Maintenance-Busy Status
When maintenance-busy is enabled and a trunk cannot be seized for an
outgoing call, the trunk is automatically put into a maintenance-busy state.
When a trunk is in a maintenance-busy state, no outgoing calls can be placed
on it. However, the trunk can still receive incoming calls.
NOTE:
Maintenance-busy does not apply to DID trunks, since DID trunks cannot
be used to make outgoing calls.
While the trunk is in a maintenance-busy state, the software periodically runs
tests, attempting to seize the trunk:
■
If the seizure is unsuccessful, the trunk stays in a maintenance-busy
state.
■
If the seizure is successful, the trunk is placed back in service.
■
If a test is running when an incoming call is received on the trunk, the
test is dropped and the call is processed.
No more than 50 percent of trunks in a pool can be in maintenance-busy states
at one time. The only exceptions are as follows:
■
User-imposed maintenance-busy (for example, module replacement)
■
Module maintenance-busy (for example, a loss-of-service alarm in the
100D module)
■
No external release at the central office end of the line
■

Permanent Errors
A permanent error is entered in the error logs when more than 50 percent of
analog trunks in a pool are maintenance-busy. When the maintenance-busy
level falls below 50 percent, the system automatically removes the permanent
error.
NOTE:
Make sure that modules are not in a maintenance-busy state during a
backup procedure. Any module in a maintenance-busy state is recorded
as such on the backup disk.
Maintenance-Busy Causes
The causes of maintenance-busy vary according to the type of trunk and are
detailed in the following sections.
Ground-Start (GS) Trunks
The following events cause maintenance-busy on a ground-start trunk:
■
A seizure of the trunk is attempted that results in incomplete
handshaking (or no loop current) between the central office (CO) and
the system.
After four occurrences, the trunk is put into a maintenance-busy state
and a permanent error is logged.
■
The CO fails to disconnect when the GS trunk is dropped by the system.
After two occurrences, the trunk is put into a maintenance-busy state
and a permanent error is logged.
Loop-Start (LS) Trunks
No loop current exists when the LS trunk is seized. The port is marked
maintenance-busy, and a permanent error is logged after four occurrences.
Tie Trunks
The following events cause maintenance-busy on a tie trunk:
MERLIN LEGEND Communications System Release 6.1

Checking Ports
Issue 1
August 1998
Page 5-7
■
A seizure of an outgoing tie trunk fails.
■
A transient error is reported. After four unsuccessful seizure attempts,
the port is marked maintenance-busy and the error becomes
permanent.
■
The CO fails to disconnect.
■
A transient error is reported. After two occurrences, the port is marked
maintenance-busy and the error becomes permanent.
NOTE:
The test is not run on auto-out tie trunks.

Auditing DS1 PRI B-Channels
The Auditing Lines and Auditing Calls procedures initiate an audit. Once an
audit is initiated, you need to wait for the far end to send a message, which
usually takes about four minutes. After waiting four minutes, check the error
logs to see if any new PRI errors have occurred.
■
Auditing Lines. If troubleshooting indicates problems with PRI lines
between the control unit and the CO, this audit, if successful, fixes the
problem. It allows either side of the PRI interface to synchronize both
ends by exchanging messages.
■
Auditing Calls. If troubleshooting indicates problems with PRI calls to or
from MLX telephones, this audit, if successful, fixes the problem. It
allows either side of the PRI interface to synchronize both ends by

Private Network Calling Problems
Issue 1

Page 5-41
Private Network Calling Problems
In Release 6.0 and later systems (Hybrid/PBX mode), when a system is
configured in a private network, various calls placed on one switch to another
switch may not complete correctly.
NOTE:
If your private network consists of more than two systems, a system
manager in the private network should be appointed to maintain system
forms for all systems in the private network. Any local modifications
should be cleared with this coordinating system manager, who must
ensure that changes to a local system do not have undesirable effects on
the private network as a whole. When modifications are made, he or she
should see that corresponding changes are made, as necessary, at
private networked systems. If your private network consists of two
systems, the managers should work together to assess and agree upon
any changes.
Troubleshooting Guidelines and Preparation
Before troubleshooting problems, obtain copies of your system’s planning
forms. Many of the solutions offered in this chapter require that you contact the
coordinating system manager in your private network, who maintains records of
how systems in your private network are programmed and keeps them up to
date. Problems can occur when changes are made in a private network without
considering the needs of the private network as a whole. In particular, changes
to local and non-local dial plans, Uniform Dial Plan (UDP) routes, Automatic
Route Selection (ARS) routes, and remote access settings can have
unintended effects on other systems in your private network.
To solve a problem, you may need to perform system programming using your
MLX-20L programming console or PC equipped with System Programming and
Maintenance (SPM) software.
Most of the problems outlined here can be solved by system managers working
together in a two system private network or with the coordinating system
manager in a larger private network. However, some problems require the
MERLIN LEGEND Communications System Release 6.1

intervention of a Lucent Technologies technician. In the USA only, Lucent
Technologies provides a toll-free customer Helpline (1 800 628-2888) 24 hours
a day. You may want to allow only the coordinating system manager to contact
the Helpline, because this person has the complete information that allows
Lucent Technologies technicians to understand problems that you are
experiencing. Under certain circumstances, you may be charged for
consultation with Helpline personnel. Contact your Lucent Technologies
representative or authorized dealer, if you have any questions concerning
consultation charges.
The troubleshooting instructions in this chapter provide information about
reviewing current programming on your local system. You can find out about
current programming in the following three ways:
■
System Forms. Review the filled-out system form that includes the
programming information you need. This method requires that forms be
available and up-to-date.
■
System Reports. Appendix B of Network Reference, “Sample Reports,”
includes samples of reports that you may require when troubleshooting
private network problems, along with the menu options for selecting
each report. To see a report, select the 3ULQW option on the System
Programming menu and then choose a report. The Feature Reference,
Appendix F, includes samples of all system reports.
■
System Programming. Many of the system programming procedures
that you may need to perform are summarized in Chapter 5, “System
Management” of Network Reference. System Programming includes
instructions for accessing system programming by using the MLX-20L
console or SPM software on a personal computer. The troubleshooting
instructions also cite procedures from System Programming .
The next topic provides specific information to help you review non-local
extension ranges, patterns, and routing on your system. This information is
required for several of the troubleshooting procedures in this chapter.

Private Network Calling Problems
Reviewing the Non-Local Dial Plan and
Routing
Some of the troubleshooting steps in this chapter require that you review the
extension ranges programmed in the non-local dial plan and/or the routing for
private network calls. Use one of the following three methods to do this:
■
System Form. Check System Non-Local UDP Administration Form in the
Installation Specification before proceeding. This form summarizes the
extension ranges and routing for the patterns programmed in your
system. For each route, the pool number, programmed digit
manipulation, the Facility Restriction Level (FRL) value are listed, and
the voice/data attribute is listed.
■
System Report. To see a system print report of existing non-local
extension ranges, patterns, and routes, select the 3ULQW option on the
System Programming menu and then choose 1RQ/FO8'3. Appendix B,
“Network Reports” of Network Reference, includes a sample.
■
System Programming. To check the current call routing on a system,
consult “UDP Routing” in Chapter 3 of System Programming .
Alternatively, follow one of the summary procedures listed below,
starting from the System Programming menu on your console or PC.

Call to a Non-Local Extension:
Unexpected Busy Tone
This topic discusses unexpected busy tones that may be caused by system
features. It applies not only to regular calls from one private network extension
to another but also to remote access calls that are routed among private
network systems. “Call to Non-Local Extension: Silence or Fast Busy Tone” in
Chapter 6 of Network Reference, outlines possible causes for a busy tone that
relate either to system programming of facilities or to call routing.
As a first step, the caller should try using Callback. All available local routes for
the call may be busy, and Automatic or Selective Callback allows the call to
queue for the next available tandem trunk assigned to the Route 1 pool.
If a user is having trouble with the Callback feature, see “Callback Does Not
Work” in Chapter 6 of Network Reference.
If the wait time for an available local trunk is unacceptable, you may be able to
change the local extension or barrier code FRL and/or route FRLs for the UDP
pattern in order to make more routes available for the call.
If you want to make changes in FRLs for routes, speak with the coordinating
system manager for your private network and consult the following resources:
■
“How Facility Restrictions Levels Work in a Network” in Chapter 4 of
Network Reference discusses FRL planning in detail.
■
To change a UDP route FRL, see “Uniform Dial Plan Routing” in Chapter
5 of Network Reference, or “UDP Routing” in Chapter 3 of System
Programming.
■
To change the extension FRL, see System Programming, Chapter 3,
“Programming Procedures.”
■
To change the FRL assigned to a remote access barrier code, see
“Remote Access” in System Programming , Chapter 3. Follow the
guidelines in “Remote Access Default Class-of-Restriction Settings” in
Chapter 4 of Network Reference.

! SECURITY ALERT:
FRLs, applied to ARS and UDP routes, default class-of-restrictions (COR)
for all tie and/or all non-tie tandem trunks, extensions, and remote access
barrier codes are particularly important for maintaining security in a private
network. Before changing FRLs in your system, check with the
coordinating system manager, who should understand the security
implications for your local system and for the private network as a whole.
Changing local FRLs may not work simply because the problem is not on the
local system. In this case, see “Call to Non-Local Extension: Silence or Fast
Busy Tone” in Chapter 6 of Network Reference.
Call to Non-Local Extension:
Silence or Fast Busy Tone
The following are likely circumstances in which silence occurs when a call is
attempted:
■
A selected tie or analog facility between the caller or called extension is
out of service. If your system is linked by tandem tie trunks and silence
occurs, call the other system on a PSTN line/trunk in order to determine
whether a tie trunk is out of service. If it is not, call the Lucent
Technologies Helpline at 1 800 628-2888; consultation charges may
apply.
■
No Touch-Tone Receivers (TTRs) available at a remote system when
using tie trunks. This can be verified by checking for the & error on
the error log on the remote switches. If this error persists, contact your
local service representative.
A fast busy tone can have one of several causes. Before investigating further,
check the following possibilities:
■
A technician may be performing maintenance on local tandem trunks or
non-local tandem trunks included in the routes for the call.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Private Network Calling Problems
Issue 1
August 1998
Page 5-46
■
A power failure may have occurred at the destination system or at
another private networked system whose tandem trunks are included in
routes for the call.
■
Some of the problems described in this section can occur when a
system manager makes a change in a private networked system’s local
dial plan, non-local dial plan, switch identifier, or DS1 Switch Type
setting. Ensure that your private network system forms are kept
up-to-date and that changes are cleared with the coordinating system
manager.
Possible Cause 1: All programmed available routes for the call are busy.
What to do: Note the extension number range(s) being called. Check that the
pattern assigned to the range includes routes that include pools that have a
sufficient number of trunks to handle the call volume.
■
If you’re not sure of the pattern number being used to route calls in your
local system, see “Reviewing the Non-Local Dial Plan and Routing” in
Chapter 6 of Network Reference.
■
To add different routes that can handle the call, consult the coordinating
system manager and see “Uniform Dial Plan Routing” in Chapter 5 of
Network Reference, or “UDP Routing” in Chapter 3 of System
Programming.
■
If you do not have enough tandem trunks to handle intersystem calls,
consider assigning pools of PSTN trunks to less preferred routes (4 or 3
and 4, for example). If you program such routes and they involve higher
toll costs than routes that specify tandem facilities, you may need to
adjust extension and route FRLs in order to restrict access to them. Be
sure that you discuss any changes with the coordinating system
manager.
■
If the routing is correct and enough routes are included in the pattern,
but the problem persists, check if PRI lines are used. If they are, check
the error log for D-channel inoperative and loss of signal alarms
indicating lines are inoperative. If the D-channel inoperative alarm has
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Private Network Calling Problems
Issue 1
August 1998
Page 5-47
occurred, check the CSU/DSU associated with the line for correct
programming. If the loss at signal alarm has occurred, check for open
cables, etc. If these conditions are not present, go to Possible Cause 3.
Possible Cause 2: Callback Queuing is not used.
What to Do: All available local routes for the call may be busy, and Automatic or
Selective Callback allows the call to queue for the next available tandem trunk
assigned to the Route 1 pool. As a first step, the caller should try using
Callback.
If a user is having trouble with the Callback feature, see “Callback Does Not
Work” in Chapter 6 of Network Reference.
Possible Cause 3: Not enough trunks are assigned to the pools for UDP
routes.
What to Do: Consult System Form 2c, System Numbering: Line/Trunk Jacks to
determine the assignments. To see a report of pool assignments, select the
3ULQW option on the System Programming menu and then choose7UXQN,QIR
and*HQHUDO.
■
If more trunks are available and need to be assigned, follow the
procedure in “Trunks to Pools Assignment” in Chapter 3 of System
Programming to assign more tandem trunks. All the tandem trunks in a
pool must be of the same type (tie or PRI).
■
If not enough trunks are available, consider adding more to your system.
■
If there are sufficient trunks assigned but the problem persists, go to
Possible Cause 4.
Possible Cause 4: Facilities are available but restricted and the caller is not
able to access them.
What to Do: Verify that the extension’s FRL is higher than or equal to the UDP
route FRL.
MERLIN LEGEND Communications System Release 6.1

Page 5-48
If you want to make changes in FRLs for routes, speak with the coordinating
system manager for your private network and consult the following resources:
■
“How Facility Restrictions Levels Work in a Network” in Chapter 4 of
Network Reference discusses FRL planning in detail.
■
To change a UDP route FRL, see “Uniform Dial Plan Routing” in Chapter
5 of Network Reference, or “UDP Routing” in Chapter 3 of System
Programming.
■
To change the extension FRL, see System Programming, Chapter 3,
“Programming Procedures.”
■
To change the FRL assigned to a remote access barrier code, see
“Remote Access” in System Programming , Chapter 3. Follow the
guidelines in “Remote Access Default Class-of-Restriction Settings” in
Chapter 4 of Network Reference.
! SECURITY ALERT:
FRLs, applied to ARS and UDP routes, default CORs for all tie and/or all
non-tie tandem trunks, extensions, and remote access barrier codes are
particularly important for maintaining security in a private network. Before
changing FRLs in your system, check with the coordinating system
manager, who should understand the security implications for your local
system and for the private network as a whole.
Changing local FRLs may not work simply because the problem is not on the
local system. In this case, go to Possible Cause 5.
Possible Cause 5: The FRL for the default COR for non-tie trunks (PRI) on the
remote system may be blocking tandem calls. The private network is an all-PRI
network.
What to Do: Check with the coordinating system manager so that he or she can
determine where the problem exists. This may involve more than one system,
depending upon how your private network is set up. For example, a call might
be routed across the private network in a fashion such as this:
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Private Network Calling Problems
Issue 1
August 1998
Page 5-49
Origin System A→System B→System C→Destination System D
In this configuration, the coordinating system manager must check routes and
default COR attributes for Systems B and C.
■
Check to make sure the calling restriction of the default COR is set to
unrestricted. The factory setting is outward restricted, which blocks calls
across the private network.
■
Check that the routes voice/data capability is correct for the type of call
being made. The factory setting is Both, which will support both voice
and data calls.
■
In each intervening system, compare the FRLs assigned to routes for the
call with the default COR FRL. The route FRL must be equal to or lower
than the default COR value or the call is blocked. The factory setting is
3.
■
If FRL settings are not the cause, go to Possible Cause 6.
Possible Cause 6: There may be a numbering conflict in the switch identifiers
for the trunks that carry the call. Within a private network, switch identifiers
should be unique and unambiguous. If they are not, calls may terminate
prematurely or continue to route unexpectedly.
What to Do: The coordinating system manager must check system planning
Form Non-Local UDP Administration Form in the Installation Specification and
review the switch identifiers for all systems over which calls travel to reach the
destination extension(s). To review a report including the switch identifiers
programmed on your local system, select the 3ULQW option on the System
Programming menu and then choose7UXQN,QIRand*HQHUDO.
■
If the switch identifiers are not correct, the coordinating system manager
must see that a change is made at one or more non-local systems where
the conflict exists. To change the current switch identifiers at your local
system, see “Switch Identifiers” in Chapter 5 of Network Reference, or
“UDP Facilities” in Chapter 3 of System Programming .
■
If the switch identifiers are correct and the problem persists, do one of
the following:
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Private Network Calling Problems
Issue 1
August 1998
Page 5-50
— If the call is being routed over any tandem PRI facilities, go to
Possible Cause 7.
— If the call is being routed over tandem tie trunks only, call the
Lucent Technologies Helpline at 1 800 628-2888; consultation
charges may apply.
Possible Cause 7: The Switch Type setting at both ends of a tandem PRI
facility may match.
What to Do: The coordinating system manager must check the programmed
Switch Type settings at private networked systems. Calls are not routed
properly unless the Switch Type setting is correctly programmed at the systems
on both ends of any tandem PRI facilities on the call route. If only MERLIN
LEGEND Communications Systems are included in the routing, the switch type
settings on the systems must be different. For example, if System A is
connected to System B by tandem PRI trunks, System A can be set to a switch
type of LEGEND-PBX and System B can be set to LEGEND-Ntwk. It does not
matter which system is assigned the PBX or Network switch type as long as the
switch types are different.
If a DEFINITY ECS or DEFINITY ProLogix Solutions system has its Interface
field set to Network, any MERLIN LEGEND Communications Systems
connected to it by tandem PRI trunks must specify LEGEND-Ntwk. If the
Interface field specifies User, the MERLIN LEGEND Communications System
facilities must be programmed with the LEGEND-PBX setting.
■
If the call is routed over a tandem PRI facility connected to your system,
ensure that the system at the other end of the facility is programmed
correctly to work with your own setting. Consult system Non-Local UDP
Administration Form in the Installation Specification. To see a report
including the switch type programmed for PRI facilities on your system,
select the 3ULQW option on the System Programming menu and then
choose35,,QIR.“PRI Facilities Switch Type” in Network Reference
provides summary instructions for determining the switch type
programmed at your system and changing it if necessary. “Switch Type”
in the Chapter 4 “PRI Facilities” section of System Programming gives
full details.

In Release 6.1 and later systems, the PRI Switch Type Test requests the
system at the other end to verify that the correct PRI switch type is
programmed. This test should be run only by Lucent Technologies
technicians or authorized representatives.
■
If the call is carried over other systems connected by tandem PRI
facilities, the coordinating system manger must ensure that the settings
are correct, as in this example of MERLIN LEGEND Communications
Systems:
System A LEGEND-PBX→System B LEGEND-Ntwk→System C
LEGEND-PBX
■
If the switch type settings are correct and problem persists, do one of
the following:
— If the call is a data call, go to Possible Cause 8.
— If the call is not a data call, call the Lucent Technologies Helpline
at 1 800 628-2888; consultation charges may apply.

If you have a MERLIN LEGEND system Release 6.0, or if you want more
information about the Switch Type setting, consult the system Non-Local
UDP Administration Form in the Installation Specification. To see a report
including the switch type programmed for PRI facilities on your system,
select the 3ULQW option on the System Programming menu, and then
choose35,,QIR.7KH“PRI Facilities Switch Type” section in Chapter 5
of the Network Reference provides summary instructions for
determining the switch type programmed at your system and changing
it if necessary. The procedure for “Switch Type” in the “PRI Facilities”
section of Chapter 3 of System Programming gives full details.
■
If the call is carried over other systems connected by tandem PRI
facilities, the coordinating system manger must ensure that the settings
are correct, as in this example of MERLIN LEGEND Communications
Systems:
System A LEGEND-PBX→System B LEGEND-Ntwk→System C LEGEND-PBX
■
If the switch type settings are correct and problem persists, do one of
the following:
— If the call is a data call, go to Possible Cause 8.
— If the call is not a data call, call the Lucent Technologies Helpline
at 1 800 628-2888; consultation charges may apply.
Possible Cause 8: The FRL for the default COR for tie trunks (T1-emulated
voice or data, or analog) on the remote system may be blocking tandem calls.
The private network includes at least one analog tie trunk.
What to Do: Check with the coordinating system manager so that he or she can
determine where the problem exists. This may involve more than one system,
depending upon how your private network is set up. For example, a call might
be routed across the private network in a fashion such as this:
Origin System A→System B→System C→Destination System D
In this configuration, the coordinating system manager must check routes and
default COR attributes for Systems B and C.

Call to Non-Local Extension: Warble Tone (Error Tone)

Page 5-55
■
Check to make sure the calling restriction of the default COR is set to
unrestricted. The factory setting is outward restricted, which blocks calls
across the private network.
■
Check that the routes voice/data capability is correct for the type of call
being made. The factory setting is Both, which will support both voice
and data calls.
■
In each intervening system, compare the FRLs assigned to routes
for the call with the default COR FRL. The route FRL must be
equal to or lower than the default COR value or the call is
blocked. The factory setting is 3.
■
If FRL settings are not the cause, go to Possible Cause 9.
Possible Cause 9: If the call is a 64-kbps data call, all routing facilities may not
support this data speed.
What to Do: Unless you are directly connected to the destination system, the
coordinating system manager must check the routes for the call. To check the
local routes, see “Reviewing the Non-Local Dial Plan and Routing” in Chapter 6
of Network Reference. To change the routing in order to specify facilities that
can handle the call, see “Uniform Dial Plan Routing” in Chapter 5 of Network
Reference, or “UDP Routing” in Chapter 3 of System Programming.
If the call is routed over any analog facilities (tie or loop-start, for example),
T1-emulated voice or data facilities, it cannot go through. If the call is routed
over PRI and/or BRI facilities, a speed of 64 kbps may be possible. If this is not
the cause of the problem, call the Lucent Technologies Helpline at 1 800
628-2888; consultation charges may apply.
Call to Non-Local Extension:
Warble Tone (Error Tone)
There are several reasons why a call to a non-local extension receives warble
tone. The first two possibilities are easy to check, because they all derive from
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Call to Non-Local Extension: Warble Tone (Error Tone)
Issue 1
August 1998
Page 5-56
the local system. The third possible cause only occurs when there are tandem
PRI facilities included in the route for the call.
Possible Cause 1: The extension number is omitted from the non-local dial
plan.
What to do: Check your system’s non-local dial plan to see whether the
destination extension number is included in a programmed extension range. If it
is not, you have solved the problem. If it is included, check all tandem switches
to ensure that the extension is in their non-local dial plans. To add the extension
to the non-local dial plan, consult the coordinating system manager and see
“Non-Local Dial Plan Numbering” in Chapter 5 of Network Reference, or
“System Renumbering” in Chapter 3 of System Programming. If it is included in
all programmed extension ranges, proceed to Possible Cause 2.
Possible Cause 2: The remote system rejects the dialed number on an all PRI
network route.
What to do: Check that the number that arrived is in the non-local dial plan. If
the number is in the non-local dial plan, verify that it is a valid extension number
for a station, adjunct, calling group, Listed Directory Number (LDN), Remote
Access, Dial 0, or ARS.
Possible Cause 3: The pattern does not have pools assigned to any routes.
What to do: Verify that the correct pattern is assigned to the range. If the
pattern is correct, assign the pools to the routes.
Possible Cause 4: The FRL assigned to the extension may not permit the call
on any of the routes included in the pattern for the call.
What to do: Look at the system form for the caller’s extension. Depending on
the type of extension (analog multiline, MLX, digital or analog data, operator,
and so on) the extension form varies. You can see a report that lists all
extension FRLs by choosing the 3ULQW option on the System Programming
menu, then selecting ([W'LUHFW. You can see programmed route FRLs by
choosing 1RQ/FO8'3from the same menu.

Page 5-57
For the call to go through, the extension FRL must be equal to or greater than at
least one of the route FRLs for the pattern that is programmed to reach the
destination extension range.
■
If it is appropriate to change the extension FRL, see “ARS
Restriction Levels for Extensions” in Chapter 4 of System
Programming.
■
If you change one or more route FRLs, the modification may
restrict or unrestrict calling from some private network extensions.
Be sure to clear any changes with the coordinating system
manager for the private network. If you decide to make this
change, see “Uniform Dial Plan Routing” on page 5–19 or “UDP
Routing” in Chapter 4 of System Programming. For details about
FRLs in private networks, see “Facility Restriction Levels and
Remote Access” on page 4–5.
■
If a local extension or route FRL is not the problem, the
coordinating system manager must determine the private
network route for the call once it leaves your local system. If there
is an intervening system between yours and the destination,
proceed to Possible Cause 5.
■
If there is no intervening system between yours and the
destination, go to Possible Cause 5.
Possible Cause 5:The FRL for the default COR for non-tie trunks (PRI) on the
remote system may be blocking tandem calls. The private network is an all PRI
network.
What to Do: Check with the coordinating system manager so that he or she can
determine where the problem exists. This may involve more than one system,
depending upon how your private network is set up. For example, a call might
be routed across the private network in a fashion such as this:
Origin System A→System B→System C→Destination System D
In this configuration, the coordinating system manager must check routes and
default COR attributes for Systems B and C.

Calls to Non-Local Extensions:
Unexpected Busy Tone
This topic discusses unexpected busy tones that may be caused by system
features. It applies not only to regular calls from one private network extension
to another but also to remote access calls that are routed among private
network systems.
Possible Cause: Intersystem callers may receive a busy tone that is
unexpected because they know that the call recipient has coverage. However,
in a private network non-local calls are treated as outside calls by the system.
The non-local extension may not have coverage for outside calls turned on.
What to Do: Depending upon how the non-local system is set up, try one of the
following techniques in order to reach the extension:
■
If the destination extension can be dialed directly via Direct
Inward Dialing (DID) or PRI dial-plan routing, try calling the
destination extension over public switched telephone network
tandem trunks. If you receive the same busy tone, then the
Coverage setting may be the problem. Call the system manager

or receptionist at the non-local system and have them check the
extension to ensure that coverage is correct and that the
extension is functional.
■
If you cannot dial the extension directly, use public switched
telephone network facilities or the non-local dial plan in order to
reach the operator for the non-local system. Have the operator
transfer you to the extension. You should be able to leave a
message for the extension user with voice mail or with the
operator.
If neither of the above methods solves the problem, call the non-local system’s
system manager or the private network coordinating system manager and
explain the situation.
Call to Non-Local Extension
Reaches Wrong Extension
Possible Cause: If a call to a non-local extension connects to the wrong
extension, one or more non-local dial plan extension ranges and/or routes may
be incorrectly programmed. Non-local dial plan numbers must be unique and
unambiguous or calls can be misrouted. Furthermore, digit absorption and
prepending for the routes must be programmed correctly.
What to Do: First, review the local routing for the call (see “Reviewing the
Non-Local Dial Plan and Routing” in Chapter 6 of Network Reference). Then
follow the steps below.
1. At your local system, ensure that routing for the destination
extension specifies pools of trunks connecting to the correct
adjacent system (if there is more than one). If digit prepending or
absorption is needed, make sure that it is correctly programmed.
If you find an error, you have solved the problem. If not, proceed
to Step 2.

Page 5-60
2. If you are directly connected to the system where the destination
extension is located, go to Step 3. Otherwise, the coordinating
system manager should repeat Step 1 for each system through
which the call is routed until you reach the system where the
destination extension is located.
3. Check with the system manager at the destination system or with
the coordinating system manager to ensure that the extension
number is in the local dial plan for that system.
NOTE:
The system does not permit programming of non-local extension ranges
that conflict with extension numbers included in the local or non-local dial
plan. However, conflicts can still arise due to digit prepending or
absorption as a call is routed across the private network.
If this is not the problem, call the Lucent Technologies Helpline at 1 800
628-2888; consultation charges may apply.
Call to Non-Local Extension:
Message from CO
Possible Cause: If someone calls a non-local extension and connects to a
central office message announcing a misdialed number or some other problem,
the call is routed over a PSTN trunk (PSTN facility pools rather than tandem
trunk pools are sometimes assigned to secondary UDP routes such as Routes
3 or 4). Problems can occur when the programming for a PSTN route does not
at least prepend the correct digits (as in 555, for a local access call, or 1555 for
a toll access call prefixed before a 4-digit extension number) and possibly
absorb digits as well, in order for the call to be directed properly.
What to Do: Check the UDP range for the pattern to which the dialed extension
is assigned. See “Reviewing the Non-Local Dial Plan and Routing” in Chapter 6
of Network Reference for instructions.

Page 5-61
If there is no error in the local programming and there is an intervening system
between yours and the system where the destination extension is located,
speak with the coordinating system manager. The coordinating system
manager should check the intervening system’s UDP tables for proper digit
manipulation. He or she can determine whether the routing problem is on that
system.
If this is not the problem, call the Lucent Technologies Helpline at 1 800
628-2888; consultation charges may apply.
Transfer to Non-Local Extension Not
Completed
There are several possible causes for an incomplete transfer. They are very
easy to check.
■
Voice-Announced Transfer. Voice-announced transfers cannot be
made to non-local extensions.
■
Transfer from PassageWay Telephony Services Client. Transfers
with consultation cannot be made from PassageWay Telephony
Services clients to non-local extensions. The user must make
such a transfer by using a telephone.
NOTE:
PassageWay Telephony Services clients cannot use an application to
transfer calls across the private network. The user must make transfers
manually using a telephone. If the transfer recipient is a PassageWay
Telephony Services client, only the transfer originator calling information
is delivered to the extension, not information about the original caller.
■
PSTN Trunk Transfer. The system permits trunk-to-trunk transfers
of inside or outside calls to non-local extensions, regardless of
whether system programming has prohibited trunk-to-trunk
transfer. However, trunk-to-trunk transfer does not work under the
following circumstances:
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Transfer Call to Non-Local Extension Does Not Return
Issue 1
August 1998
Page 5-62
— Trunk-to-trunk transfer is prohibited at the transferring
extension and the call is an outside call being transferred
to a local PSTN line/trunk.
— The transfer originator is attempting to transfer an outside
PSTN or private network call to or from a loop-start line that
does not have reliable disconnect. All loop-start lines
connected to private networked systems must have
reliable disconnect.
If the problem persists, call the Lucent Technologies Helpline at 1 800
628-2888; consultation charges may apply.
Transfer Call to
Non-Local Extension
Does Not Return
Possible Cause: If a transfer to a non-local extension cannot be completed
(due to the extension being busy, for example), it only returns when the call is
routed over tandem PRI facilities, not tandem tie trunks or the PSTN trunks that
may be used for less preferred routes.
What to Do: Review the routing for the call (see “Reviewing the Non-Local Dial
Plan and Routing” in Chapter 6 of Network Reference for instructions), and
check with the coordinating system manager if necessary. If the call is routed
over any tandem tie trunks or over any PSTN facilities, you have solved the
problem.
If the call is routed only over tandem PRI facilities, call the Lucent Technologies
Helpline at 1 800 628-2888; consultation charges may apply.

Conference: Cannot Add Call
Issue 1
August 1998
Page 5-63
Conference: Cannot Add Call
Non-local extensions are treated as outside parties for the purpose of transfer.
A non-local conference participant takes up one of the two outside calls
permitted in a conference.
NOTE:
A PassageWay Telephony Services client cannot add a non-local
extension to a conference. The user must add the conferee by using a
telephone. If a conferee is dropped, the PassageWay Telephony Services
client display does not so indicate. A PassageWay Telephony Services
client, when added to a conference, only sees information about the
conference originator, not about other conferees.
If this is not the problem, call the Lucent Technologies Helpline at 1 800
628-2888; consultation charges may apply.
DID Calls Not Completed
There are several reasons why Direct Inward Dialing (DID) calls across a
private network may not complete, either due to busy facilities or to faulty
programming. The coordinating system manager may need to address the
problem.
Possible Cause 1: All programmed and available routes for the call are busy.
What to do: This problem solves itself when traffic decreases. Only address the
problem if it persists.
Note the extension number range for the DID destination. At the system where
the call is received from the PSTN, check that the pattern assigned to the range
includes sufficient different routes with pools (of tandem and/or PSTN facilities)
to handle the call volume. This is accomplished by checking the error for errors
4C01 (Pool Empty), 4C02 (Pool Busy), or 4C03 (Pool Busy and/or
Out-of-Service). If any of these error codes are present, check the pool index on
MERLIN LEGEND Communications System Release 6.1

DID Calls Not Completed

the maintenance screen to determine if it matches the pool used to deliver the
call. If it matches, check occurrence times and count. If the count is too high and
the occurrences indicate the problem occurred within the duration of the
occurrences, consider changing the routing of the call, pool sizes, or add trunks
to the pool if empty.
■
To add more routes that can handle the call, see “Uniform Dial
Plan Routing” in Chapter 5 of Network Reference, or “UDP
Routing” in Chapter 3 of System Programming.
■
If more trunks are available and need to be assigned, follow the
procedure in “Trunks to Pools Assignment” in Chapter 3 of
System Programming to assign more tandem trunks. All the
tandem trunks in a pool must be of the same type (tie or PRI).
■
If not enough trunks are available, consider adding more to the
system.
■
If there are sufficient trunks assigned and the problem persists,
the cause of the problem may be at an intervening system
between the one where the calls are received from the PSTN and
the destination. Go to Possible Cause 2.
■
If there are sufficient trunks and routes and there are no
intervening systems between the one where the calls are
received from the PSTN and the destination, contact the provider
of the DID service. If this does not solve the problem, call the
Lucent Technologies Helpline at 1 800 628-2888; consultation
charges may apply.
Possible Cause 2: The FRL for the default COR for all tie (T-1 emulated voice
or data, or analog) or non-tie trunks (PRI) on the remote system may be
blocking tandem calls.
What to Do: Check with the coordinating system manager so that he or she can
determine where the problem exists. This may involve more than one system,
depending upon how your private network is set up. For example, a call might
be routed across the private network in a fashion such as this:
Origin System A→System B→System C→Destination System D
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
ARS Calls Are Blocked
Issue 1
August 1998
Page 5-65
In this configuration, the coordinating system manager must check routes and
default COR attributes for Systems B and C.
■
Check to make sure the calling restriction of the default COR is
set to unrestricted. The factory setting is outward restricted,
which blocks calls across the private network.
■
Check that the routes voice/data capability is correct for the type
of call being made. The factory setting is Both, which will support
both voice and data calls.
■
In each intervening system, compare the FRLs assigned to routes
for the call with the default COR FRL. The route FRL must be
equal to or lower than the default COR value or the call is
blocked. The factory setting is 3.
■
If FRL settings are not the cause, call the Lucent Technologies
Helpline at 1 800 628-2888; consultation charges may apply.
ARS Calls Are Blocked
Check Possible Cause 2 listed in “DID Calls Not Completed” of the previous
section. When an ARS call is routed across the private network, it can be
intercepted because the default COR FRL at a private networked system is
lower than the ARS route (or the UDP route if the system is sending the call to
another private networked system).
If this is not the cause, check the Disallowed List entries applied to default COR
settings at systems where the call is routed either to the PSTN or to another
system in the private network. Compare the entries to the dialed digits; a
Disallowed List may be blocking the call. If it is necessary to change the
Disallowed List, see “Disallowed Lists” in Chapter 3 of System Programming.
Check the ARS programming to verify that the remote machine’s ARS code is
being prepended. Verify that switch identifiers have been assigned to all private
network tandem trunks.
If this does not solve the problem, call the Lucent Technologies Helpline at
1 800 628-2888; consultation charges may apply.

Callback Does Not Work
Callback allows queueing for an available line/trunk connected to the local
system. If a user attempts an ARS- or UDP-routed call and hears a busy signal
or warble tone, the signal may be derived from a non-local system’s tandem or
PSTN facilities. If this is the case, Callback does not work. When all available
routes on the local system are busy, a caller can use Callback to wait for an
available facility in the Route 1 pool.
Private Network Call
Transmission Level
(Volume) Too Low or Too High
When transmission levels are too high or too low, the coordinating system
manager must investigate the cause.
Possible Cause 1: Switch identifiers programmed incorrectly.
What to Do: Refer to the table below as you examine the problem. It lists the
rules for programming switch identifiers. At each system in a private network,
each tandem trunk is programmed (individually or as part of a block of trunks) to
indicate the type of system connected to the other end of the trunk as well as
the distance between the connected systems.

NOTE:
DEFINITY ECS and DEFINITY ProLogix Solutions systems are beyond the
scope of this guide. For information about how these systems identify
tandem facilities, see the documentation for the applicable system.
Follow the steps below to check on the problem.
1. Check the routing for the call, and identify each system where the
call is routed, including the system where the call originated or
was received from the public switched telephone network. See
“Reviewing the Non-Local Dial Plan and Routing” in Chapter 6 of
Network Reference for instructions.
2. As necessary, note the switch identifier programmed on each
system for the trunks that carry the calls. To review a report
including the switch identifiers programmed on a system, select
the 3ULQW option on the System Programming menu and then
choose7UXQN,QIRand *HQHUDO.
3. Look for switch identifiers that incorrectly specify the distance
between systems or that specify the incorrect type of system. The
diagram below shows how switch identifiers might be
programmed at either end of tandem trunks in a hypothetical
private network. A switch identifier is programmed to identify the
system at the opposite end of the tandem trunk. In the example,
all three switches are MERLIN LEGEND Communications
Systems. On the facility that links Systems A and B, the system
managers program identifiers to indicate that they are within 200
miles of one another. Next to the name of each system, is the
switch identifier associated with that switch. The switch is

4. If any of the programming is incorrect, one or more system
managers must correct it. The coordinating system manager
must clear any changes. To change the switch identifiers at your
local system, see “Switch Identifiers” on page 5–13 or “UDP
Facilities” in Chapter 3 of System Programming . If the
programming appears to be correct, skip to Step 6.
5. Make some test calls across the private network. If calls are at the
proper levels, the problem is solved. If transmission levels are still
incorrect, proceed to Step 6.
6. If the identifiers appear correct but the distance between systems
is between 180 and 220 miles, you may need to experiment with
switch identifiers in order to achieve the correct transmission
levels. Return to Step 4.
If changing one or more switch identifiers do not solve the problem,
Possible Cause 2: More than three analog spans are involved in the call.
What to Do: This may occur when calls are transferred or forwarded multiple
times across analog facilities. Consider changing to digital facilities if this

MLX Displays: Private Network Call
Display Problems
There are several possible causes for this problem, all of them easy to check:
Possible Cause 1: Non-local extension calls and outside calls routed on
tandem tie trunks display at recipient MLX display telephones as outside calls,
for example, 7,(75..
What to Do: Check the call routing and find out whether any tandem tie trunks
are included in the route. You may need to contact the coordinating system
manager. If the call originated from the PSTN on a PRI or BRI facility with
Automatic Number Identification (ANI), the original calling party information
displays when private network routing is over tandem PRI trunks only. Check
the call routing and see whether any tandem tie trunks are included in the route.
Possible Cause 2: Call transferred to the extension.
What to Do: If the call was transferred to the extension, only the transfer
originator information displays, not the name and/or number of the original
caller, even if PRI ANI was available for the original call.
Possible Cause 3: Display Preference setting for MLX incorrect
What to Do: If the call route for an intersystem call includes only tandem PRI
trunks and the call was not transferred, the Display Preference setting for the
MLX display telephone extension may not be programmed as you expect. The
factory setting displays the caller’s extension number. Check System Planning
Form, MLX Telephones, for the recipient extension or see “Display Preferences
for Intersystem Calls” in Chapter 5 of Network Reference to check the setting

through system programming. If you see the word “Ext” in the display, change
the programming to Both.
You can see a report for the extension, showing the display preference, by
choosing the 3ULQW option on the System Programming menu, then selecting
([W,QIRand entering the extension number. If the display shows a 10-digit
ANI as 35,75.([W, you may want to change the display
option from Name to Both and then the display would look like 35,75.
Possible Cause 4: Transfer completed too quickly.
What to Do: Callers must wait at least two seconds before completing
transfers.
If none of these factors caused the problem, call the Lucent Technologies
Helpline at 1 800 628-2888; consultation charges may apply.
PassageWay Call Display Problems
In private networks, calls to and from PassageWay Telephony services clients
may not display or initiate screen pop as expected. The operation varies
according to the application, according to the following rules:
■
For an outgoing call, if the PassageWay Telephony Services
application uses the length of a destination telephone number to
differentiate PSTN calls from UDP calls, a PassageWay Telephony
Services client displays a non-local extension call in the same
way as it does inside calls.
■
For an outgoing call, if the PassageWay Telephony Services
application uses receipt of the Network Reached event to
differentiate PSTN calls from inside calls, a PassageWay
Telephony Services client displays a non-local extension call or
other UDP-routed call in the same way as it does an outside call
made to the public switched telephone network.

ARS Calls Go to System Operator (Unassigned Extension)
Page 5-71
■
For an incoming call, if the PassageWay Telephony Services
application uses the length of ANI information to differentiate
PSTN calls from UDP calls, a PassageWay Telephony Services
client displays a non-local dial plan call as an inside call.
■
For an incoming call, if the PassageWay Telephony Services
application uses the presence of a trunk identifier in the delivered
event to differentiate PSTN calls from UDP calls, a PassageWay
Telephony Services client displays a non-local dial plan call in the
same way it does a PSTN call.
■
For an incoming PSTN call that enters the private network on a
PRI trunk with an ANI of length shorter than seven digits and
crosses PRI tandem trunks only, the recipient PassageWay
Telephony Services client display depends on the PassageWay
Telephony Services application implementation.
If none of these factors explain the problem, contact the application provider. If
the application provider instructs you to do so, call the Lucent Technologies
Helpline at 1 800 628-2888; consultation charges may apply.
ARS Calls Go to System
Operator (Unassigned Extension)
Possible Cause: System managers in your private network may have set up
ARS and remote access to route outgoing calls to PSTN facilities on switches
where these calls are most economical.
What to Do: If such calls are reaching a system operator (unassigned
extension) on a private networked system, rather than being routed to the
PSTN, the coordinating system manager must check the tandem facilities that
carry calls to the system where the operator is located. The problem is caused
when one or more tandem trunks has no switch identifier (the factory setting).
If this is not the problem, call the Lucent Technologies Helpline at 1 800
628-2888; consultation charges may apply.

DID or PRI Dial-Plan Routed Calls Not Completed
Issue 1
August 1998
Page 5-72
DID or PRI Dial-Plan Routed Calls
Not Completed
Possible Cause 1: DID and PRI calls cannot be routed to a 5-digit DEFINITY
ECS or DEFINITY ProLogix Solutions system.
What to Do: Verify system programming and the digits received from the
PSTN. Refer to Chapter 5, “Non-Local Dial Plan Number” for details on
programming required.
Possible Cause 2: DID or PRI routing not correct.
What to Do: The coordinating system manager should check the DID or PRI
routing. These calls may come into one private networked switch and be routed
across the private network to an extension on another system in the private
network. The routing must specify the correct tandem trunk pools, extension
numbers, and digit manipulation.
If the routing is correct, contact the service provider. If the service provider
instructs you to do so, call the Lucent Technologies Helpline at 1 800 628-2888;
consultation charges may apply.
Excessive Line Noise on Voice and
Data Calls
Possible Cause: Clocks are not properly synchronized.
What to Do: The coordinating system manager should check error logs at
problem systems. If slips are occurring at a high rate or an alarm was raised,
clock synchronization is a problem. The coordinating system manager should
then check the programming for the PRI tandem trunk(s) and/or PSTN digital
facilities that carry the calls. A single clock source is used for all private
networked systems so that calls are properly synchronized. For details about
clock synchronization in a private network, see “Clock Synchronization” in

Chapter 5 of Network Reference. To program clock synchronization, see
Chapter 3 of System Programming.
If the clock source is correct, ensure that the specified port is functioning

Helpline at 1 800 628-2888; consultation charges may apply.
Station Message Detail Recording
(SMDR) Reports Do Not Include
Calls across the Private Network
SMDR reports may report calls using more than one call record on more than
one system. Depending upon how SMDR is programmed and how calls are
routed, you may need to consult several SMDR records to trace a call that is
routed over private network tandem trunks. To log private network calls, SMDR
should be programmed to report both incoming and outgoing calls.

The diagram above shows how a single call, routed across a private network, is
both an incoming and an outgoing call in the same system. For private network
calls, outgoing call records report the incoming tandem trunk number in the
STN. field (see System B above). Dialed digits shown on the report do not
reflect any digit manipulation (addition or absorption) performed by the local
system.
Calls across the private network are not recorded, even at a tandem switch, if
the call is not answered unless the outgoing facility is a loop-start or
ground-start trunk. Then calls are logged, even unanswered calls.
If the system date and time are not synchronized across the private network, it
may be hard to recognize the records for a single call, even when the systems

Security of Your System: Preventing Toll Fraud
Issue 1
August 1998
Page A-11
Security of Your System:
Preventing Toll Fraud
As a customer of a new telephone system, you should be aware that there is an
increasing problem of telephone toll fraud. Telephone toll fraud can occur in
many forms, despite the numerous efforts of telephone companies and
telephone equipment manufacturers to control it. Some individuals use
electronic devices to eliminate or falsify records of these calls. Others charge
calls to someone else’s number by illegally using lost or stolen calling cards,
billing innocent parties, clipping on to someone else’s line, or breaking into
someone else’s telephone equipment physically or electronically. In certain
instances, unauthorized individuals make connections to the telephone network
through the use of the Remote Access features of your system.
The Remote Access features of your system, if you choose to use them, permit
off-premises callers to access the system from a remote telephone by using a
telephone number with or without a barrier code. The system returns an
acknowledgment signaling the user to key in his or her barrier code, which is
selected and programmed by the system manager. After the barrier code is
accepted, the system returns dial tone to the user. In Release 3.1 and later
systems, barrier codes are by default restricted from making outside calls. In
prior releases, if you do not program specific outward calling restrictions, the
user will be able to place any call normally dialed from a telephone associated
with the system. Such an off-premises network call is originated at, and will be
billed from, the system location.
The Remote Access feature, as designed, helps the customer, through proper
administration, to minimize the ability of unauthorized persons to gain access to
the private network. Most commonly, phone numbers and codes are
compromised when overheard in a public location, through theft of a wallet or
purse containing access information, or through carelessness (for example,
writing codes on a piece of paper and improperly discarding it). Additionally,
hackers may use a computer to dial an access code and then publish the
information to other hackers. Enormous charges can be run up quickly. It is the
customer’s responsibility to take the appropriate steps to properly implement
the features, evaluate and administer the various restriction levels, protect

access codes, and distribute access codes only to individuals who have been
fully advised of the sensitive nature of the access information.
Common carriers are required by law to collect their tariffed charges. While
these charges are fraudulent charges made by persons with criminal intent,
applicable tariffs state that the customer of record is responsible for payment of
all long-distance or other private network charges. Lucent Technologies cannot
be responsible for such charges and will not make any allowance or give any
credit for charges that result from unauthorized access.
To minimize the risk of unauthorized access to your communications system:
■
Use a nonpublished Remote Access number.
■
Assign access codes randomly to users on a need-to-have basis,
keeping a log of all authorized users and assigning one code to one
person.
■
Use random-sequence access codes, which are less likely to be easily
broken.
■
Use the longest-length access codes the system allows.
■
Deactivate all unassigned codes promptly.
■
Ensure that Remote Access users are aware of their responsibility to
keep the telephone number and any access codes secure.
■
When possible, restrict the off-network capability of off-premises callers,
using calling restrictions, Facility Restriction Levels (Hybrid/PBX mode
only), and Disallowed List capabilities. In Release 3.1 and later systems,
a prepared Disallowed List (number 7) is provided and is designed to
prevent the types of calls that toll-fraud abusers often make.
■
When possible, block out-of-hours calling.
■
Frequently monitor system call detail reports for quicker detection of any
unauthorized or abnormal calling patterns.
■
Limit Remote Call Forwarding to persons on a need-to-have basis.
■
Change access codes every 90 days.

Toll Fraud Prevention
Toll fraud is the unauthorized use of your telecommunications system by third
parties to make long distance telephone calls. Under the law, you, the customer,
are responsible for paying part or all of those unauthorized calls. Thus, the
following information is of critical importance.
Unauthorized persons concentrate their activities in two areas with the MERLIN
LEGEND Communications System:
■
They try to transfer out of the MERLIN LEGEND Communications System
to gain access to an outgoing trunk and make long-distance calls.
■
They try to locate unused or unprotected mailboxes and use them as
drop-off points for their own messages.
The following is a discussion of how toll fraud is often perpetrated and ways to
prevent unauthorized access that can lead to toll fraud.
Physical Security, Social Engineering, and
General Security Measures
Criminals called hackers may attempt to gain unauthorized access to your
communications system and voice messaging system in order to use the
system features. Hackers often attempt to trick employees into providing them
with access to a private network facility (line/trunk) or a private network
operator. This is referred to as social engineering. Hackers may pose as
telephone company employees and employees of Lucent Technologies or your
authorized dealer. Hackers will go through a company’s trash to find directories,
dialing instructions, and other information that will allow them to break into the
system. The more knowledgeable they appear to be about the employee
names, departments, telephone numbers, and the internal procedures of your
company, the more likely it is that they will be able to trick an employee into
helping them.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Toll Fraud Prevention
Issue 1
August 1998
Page A-14
Preventive Measures
Take the following preventive measures to limit the risk of unauthorized access
by hackers:
■
Provide good physical security for the room containing your
telecommunications equipment and the room with administrative tools,
records, and system manager information. These areas should be
locked when not attended.
■
Provide a secure trash disposal for all sensitive information, including
telephone directories, call accounting records, or anything that may
supply information about your communications system. This trash
should be shredded.
■
Educate employees that hackers may try to trick them into providing
them with dial tone or dialing a number for them. All reports of trouble,
requests for moving extensions, or any other administrative details
associated with the MERLIN LEGEND Communications System should
be handled by one person (the system manager) or within a specified
department. Anyone claiming to be a telephone company
representative should be referred to this person or department.
■
No one outside of Lucent Technologies needs to use the MERLIN
LEGEND Communications System to test facilities (lines/trunks). If a
caller identifies him or herself as an Lucent Technologies employee, the
system manager should ask for a telephone number where the caller
can be reached. The system manager should be able to recognize the
number as an Lucent Technologies telephone number. Before
connecting the caller to the administrative port of the MERLIN LEGEND
Communications System, the system manager should feel comfortable
that a good reason to do so exists. In any event, it is not advisable to
give anyone access to private network facilities or operators, or to dial a
number at the request of the caller.
■
Any time a call appears to be suspicious, call the Lucent Technologies
GBCS Fraud Intervention Center at 1 800 628-2888 (fraud intervention
for System 25, PARTNER® and MERLIN® systems).

fraud detection services, CAS with HackerTracker® , and CAT Terminal
with Watchdog. Call 1 800 638-7233 to get more information on these
Lucent Technologies fraud detection services and products.
Security Risks Associated with Transferring
through Voice Messaging Systems
Toll fraud hackers try to dial into a voice mailbox and then execute a transfer by
dialing27. The hacker then dials an access code (either for Automatic Route
Selection or a pooled facility code) followed by the appropriate digit string to
either direct dial or access a private network operator to complete the call.
NOTE:
In Release 3.1 and later systems, all extensions are initially and by default
restricted from dial access to pools. In order for an extension to use a
pool to access an outside line/trunk, this restriction must be removed.
Preventive Measures
Take the following preventive measures to limit the risk of unauthorized
transfers by hackers:
■
Outward restrict all MERLIN LEGEND voice mail port extensions. This
denies access to facilities (lines/trunks). In Release 3.1 and later
systems, voice mail ports are by default outward restricted.
■
As an additional security step, private network dialing for all extensions,
including voice mail port extensions, should be processed through ARS
using dial access code .
! SECURITY ALERT:
The MERLIN LEGEND system ships with ARS activated with all
extensions set to Facility Restriction Level 3, allowing all international
calling. To prevent toll fraud, ARS Facility Restriction Levels (FRLs)
should be established using:
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Toll Fraud Prevention
Issue 1
August 1998
Page A-16
■
FRL 0 for restriction to internal dialing only
■
FRL 2 for restriction to local private network calling only
■
FRL 3 for restriction to domestic long distance (excluding area
code 809 for the Dominican Republic as this is part of the North
American Numbering Plan, unless 809 is required)
■
FRL 4 for international calling
■
In Release 3.1 and later systems, default local tables are
factory-assigned an FRL of 2. This simplifies the task of restricting
extensions: the FRL for an extension merely needs to be changed
from the default of 3.
■
Each extension should be assigned the appropriate FRL to match
its calling requirements. All voice mail port extensions not used
for Outcalling should be assigned to FRL 0 (the factory setting in
Release 3.1 and later).
■
Deny access to pooled facility codes by removing pool dial-out codes
70, 890-899, or any others on your system.
■
Create a Disallowed List or use the pre-prepared Disallowed List
number 7 (Release 3.1 and later systems only) to disallow dialing 0, 11,
10, 1700, 1809, 1900, and 976 or 1(wildcard)976. In Release 3.1 and
later systems, Disallowed List number 7 does not include 800 and 1800
and 411 and 1411, but Lucent Technologies recommends that you add
them. Assign all voice mail port extensions to this Disallowed List.
Lucent Technologies recommends assigning Disallowed List number 7.
This is an added layer of security, in case outward restriction is
inadvertently removed. (In Release 3.1 and later systems, voice
messaging ports are assigned by default to Disallowed List number 7.)
If your system is part of a private network, assign Disallowed List 7 to
Remote Access.
If Outcalling is required by voice messaging system extensions:
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Toll Fraud Prevention
Issue 1
August 1998
Page A-17
■
Program an ARS Facility Restriction Level (FRL) of 2 on voice mail port
extension(s) used for Outcalling. This allows calls to use the default local
ARS table that is defaulted to an FRL of 2 and any other ARS routes with
an FRL of 2 or less.
■
If 800 and 411 numbers are used, remove 1800, 800, 411, and 1411
from Disallowed List (number 7).
■
If Outcalling is allowed to long distance numbers, build an Allowed List
for the voice mail port extension(s) used for Outcalling. This list should
contain the area code and the first three digits of the local exchange
telephone numbers to be allowed.
■
In a private network, if your switch is outcalling only to non-local private
network extensions, program the VMI ports with an FRL of 2.
Additional general security recommended for voice messaging systems:
■
Use a secure password for the General Mailboxes.
■
The default administration mailbox, 9997, must be reassigned to the
system manager’s mailbox/extension number and securely password
protected.
■
All voice messaging system users must use secure passwords known
only to the user.
Security Risks Associated with the
Automated Attendant Feature of Voice
Messaging Systems
Two areas of toll fraud risk associated with the Automated Attendant feature of
voice messaging systems are the following:
■
Pooled facility (line/trunk) access codes are translated to a menu
prompt to allow Remote Access. If a hacker finds this prompt, the
hacker has immediate access. (In Release 3.1 and later systems, dial
access to pools is initially factory-set to restrict all extensions: to allow
pool access, this restriction must be removed by the system manager.)
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Toll Fraud Prevention
Issue 1
August 1998
Page A-18
■
If the Automated Attendant prompts callers to use Remote Call
Forwarding (RCF) to reach an outside telephone number, the system
may be susceptible to toll fraud. An example of this application is a
menu or submenu that says, “To reach our answering service, select
prompt number 5,” and transfers a caller to an external telephone
number.
■
Remote Call Forwarding can only be used securely when the central
office provides “reliable disconnect” (sometimes referred to as forward
disconnect or disconnect supervision), which guarantees that the
central office will not return a dial tone after the called party hangs up. In
most cases, the central office facility is a loop-start line/trunk which does
not provide reliable disconnect. When loop-start lines/trunks are used, if
the calling party stays on the line, the central office will return a dial tone
at the conclusion of the call, enabling the caller to place another call as
if it were being placed from your company. Ground-start trunks provide
reliable disconnect and should be used whenever possible.
Preventive Measures
Take the following preventive measures to limit the risk of unauthorized use of
the Automated Attendant feature by hackers:
■
Do not use Automated Attendant prompts for ARS Codes or Pooled
Facility Codes.
■
Assign all unused Automated Attendant Selector Codes to zero, so that
attempts to dial these will be routed to the system attendant.
■
If Remote Call Forwarding (RCF) is required, MERLIN LEGEND
Communications System owners should coordinate with their Lucent
Technologies Account Team or authorized dealer to verify the type of
central office facility used for RCF. If it is a ground-start line/trunk, or if it
is a loop-start line/trunk and central office reliable disconnect can be
ensured, then nothing else needs to be done.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Toll Fraud Prevention
Issue 1
August 1998
Page A-19
NOTE:
In most cases these will be loop-start lines/trunks without reliable
disconnect. The local telephone company will need to be involved
to change the facilities used for RCF to ground start lines/trunks.
Usually a charge applies for this change. Also, hardware and
software changes may need to be made in the MERLIN LEGEND
Communications System. The MERLIN MAIL and MERLIN
LEGEND Mail Automated Attendant feature merely accesses the
RCF feature in the MERLIN LEGEND Communications System.
Without these changes being made, this feature is highly
susceptible to toll fraud. These same preventive measures must
be taken if the RCF feature is active for MERLIN LEGEND
Communications System extensions whether or not it is accessed
by an Automated Attendant menu.
Security Risks Associated with the Remote
Access Feature
Remote Access allows the MERLIN LEGEND Communications System owner
to access the system from a remote telephone and make an outgoing call or
perform system administration, using the private network facilities (lines/trunks)
connected to the MERLIN LEGEND Communications System. Hackers,
scanning the public switched network by randomly dialing numbers with war
dialers (a device that randomly dials telephone numbers, including 800
numbers, until a modem or dial tone is obtained), can find this feature, which will
return a dial tone to them. They can even employ war dialers to attempt to
discover barrier codes.
Preventive Measures
Take the following preventive measures to limit the risk of unauthorized use of
the MERLIN LEGEND Communications System Remote Access feature by
hackers:
■
The Remote Access feature can be abused by criminal toll fraud
hackers, if it is not properly programmed. Therefore, this feature should
not be used unless there is a strong business need.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Other Security Hints
Issue 1
August 1998
Page A-20
■
It is strongly recommended that customers invest in security adjuncts,
which typically use one-time passcode algorithms. These security
adjuncts discourage hackers. Since a secure use of the Remote Access
feature generally offers savings over credit-card calling, the break-even
period can make the investment in security adjuncts worthwhile.
■
If a customer chooses to use the Remote Access feature without a
security adjunct, then multiple barrier codes should be employed, with
one per user if the system permits. The MERLIN LEGEND system
permits a maximum of 16 barrier codes.
■
The maximum length should be used for each barrier code, and should
be changed periodically. Barrier codes, like passwords, should consist
of a random, hard-to-guess sequence of digits. While MERLIN LEGEND
Release 3.0 permits a barrier code of up to 11 digits, systems prior to
Release 3.0 permit barrier codes of up to only four digits.
If Remote Access is used, an upgrade to MERLIN LEGEND Communications
System Release 3.0 is encouraged to take advantage of the longer barrier
code.
Other Security Hints
Make sure that the Automated Attendant Selector Codes do not permit outside
line selection.
Multiple layers of security are always recommended to keep your system
secure.
Following are a number of measures and guidelines that can help you ensure
the security of your communications system and voice messaging system.

Page A-21
Educating Users
Everyone in your company who uses the telephone system is responsible for
system security. Users and attendants/operators need to be aware of how to
recognize and react to potential hacker activity. Informed people are more likely
to cooperate with security measures that often make the system less flexible
and more difficult to use.
■
Never program passwords or authorization codes onto Auto Dial
buttons. Display telephones reveal the programmed numbers and
internal abusers can use the Auto Dial buttons to originate unauthorized
calls.
■
Discourage the practice of writing down barrier codes or passwords. If a
barrier code or password needs to be written down, keep it in a secure
place and never discard it while it is active.
■
Instruct operators and attendants to tell their system manager when they
answer a series of calls where there is silence on the other end or the
caller hangs up.
■
Advise users who are assigned voice mailboxes to frequently change
personal passwords and not to choose obvious passwords.
■
Ensure that the system manager advises users with special telephone
privileges (such as Remote Access, Outcalling, and Remote Call
Forwarding) of the potential risks and responsibilities.
■
Be suspicious of any caller who claims to be with the telephone
company and wants to check an outside line. Ask for a callback
number, hang up and confirm the caller’s identity.
■
Never distribute the office telephone directory to anyone outside the
company; be careful when discarding it (shred the directory).
■
Never accept collect telephone calls.
■
Never discuss your telephone system’s numbering plan with anyone
outside the company.

Educating Operators
Operators and attendants need to be especially aware of how to recognize and
react to potential hacker activity. To defend against toll fraud, operators should
follow the guidelines below:
■
Establish procedures to counter social engineering. Social engineering
is a con game that hackers frequently use to obtain information that may
help them gain access to your communications system or voice
messaging system.
■
When callers ask for assistance in placing outside or long-distance
calls, ask for a callback extension.
■
Verify the source. Ask callers claiming to be maintenance or service
personnel for a callback number. Never transfer to *10 without this
verification. Never transfer to extension 900.
■
Remove the headset and/or handset when the console is not in use.
Detecting Toll Fraud
To detect toll fraud, users and operators should look for the following:
■
Lost voice mail messages, mailbox lockout, or altered greetings
■
Inability to log into voice mail
■
Inability to get an outside line
■
Foreign language callers
■
Frequent hang-ups
■
Touch-tone sounds
■
Caller or employee complaints that the lines are busy
■
Increases in internal requests for assistance in making outbound calls
(particularly international calls or requests for dial tone)
■
Outsiders trying to obtain sensitive information
■
Callers claiming to be the “phone” company
■
Sudden increase in wrong numbers

Establishing a Policy
As a safeguard against toll fraud, follow these guidelines for your MERLIN
LEGEND Communications System and voice messaging system:
■
Change passwords frequently (at least quarterly). Changing passwords
routinely on a specific date (such as the first of the month) helps users to
remember to do so.
■
Always use the longest-length password allowed.
■
Establish well-controlled procedures for resetting passwords.
■
Limit the number of invalid attempts to access a voice mailbox to five or
less.
■
Monitor access to the MERLIN LEGEND dial-up maintenance port.
Change the access password regularly and issue it only to authorized
personnel. Disconnect the maintenance port when not in use. (However,
this eliminates Lucent Technologies 24-hour maintenance surveillance
capability and may result in additional maintenance costs.)
■
Create a communications system management policy concerning
employee turnover and include these suggestions:
— Delete all unused voice mailboxes in the voice mail system.
— If a terminated employee had Remote Access calling privileges
and a personal authorization code, remove the authorization
code immediately.
— If barrier codes and/or authorization codes were shared by the
terminated employee, these should be changed immediately.
■
Regularly back up your MERLIN LEGEND system files to ensure a timely
recovery should it be required. Schedule regular, off-site backups.
■
Keep the Remote Maintenance Device turned off when not in use by
Lucent Technologies or your authorized dealer.
■
Limit transfers to registered subscribers only.
MERLIN LEGEND Communications System Release 6.1
Maintenance and Troubleshooting 555-661-140
Issue 1
August 1998
Other Security Hints
Page A-24
■
Use the Security Violations Notification options (Mailbox Lock or
Warning Message) to alert you of any mailbox break-in attempts.
Investigate all incidents.
■
Review security policies and procedures and keep them up-to-date.
Choosing Passwords
Passwords should be the maximum length allowed by the system.
Passwords should be hard to guess and should not contain:
■
All the same numbers (for example, 1111, 666666)
■
Sequential characters (for example, 123456)
■
Numbers that can be associated with you or your business, such as
your name, birthday, business name, business address, telephone
number, or social security number.
■
Words or commonly used names.
Passwords should be changed regularly, at least on a quarterly basis. Recycling
old passwords is not recommended. Never program passwords (or
authorization codes or barrier codes) onto a speed dial button.
Improving Physical Security
You should always limit access to the system console (or attendant console)
and supporting documentation. Following are some recommendations:
■
Keep the system console and supporting documentation in an office
that is secured with a changeable combination lock. Provide the
combination only to those individuals having a real need to enter the
office.
■
Keep telephone wiring closets and equipment rooms locked.
■
Keep telephone logs and printed reports in locations that only
authorized personnel can enter.

■
Design distributed reports so they do not reveal password or trunk
access code information.
■
Keep the voice messaging system Remote Maintenance Device turned
off.
Limiting Outcalling
When Outcalling is used to contact subscribers who are off-site, use the
MERLIN LEGEND Communications System Allowed Lists and Disallowed Lists
or Automatic Route Selection features to minimize toll fraud.
If the Outcalling feature will not be used, outward restrict all voice messaging
system ports. If Outcalling will be used, ports not used for Outcalling should be
Outward Restricted (for MERLIN MAIL Voice Messaging Systems, port 2 on a
two-port system, port 4 on a four-port system, ports 5 and 6 on a six-port
system). Use Outward Restriction, Toll Restrictions, Allowed Lists, Disallowed
Lists and Facility Restrictions Levels, as appropriate to minimize the possibility
of toll fraud.
Limited Warranty and
Limitation of Liability
Lucent Technologies warrants to you, the customer, that your MERLIN
LEGEND Communications System will be in good working order on the date
Lucent Technologies or its authorized reseller delivers or installs the system,
whichever is later (“Warranty Date”). If you notify Lucent Technologies or its

Remote Administration
and Maintenance
The Remote Administration and Maintenance feature of your
telecommunications system, if you choose to use it, permits users to change the
system features and capabilities from a remote location.
The Remote Administration and Maintenance feature, through proper
administration, can help you reduce the risk of unauthorized persons gaining
access to the private network. However, telephone numbers and access codes
can be compromised when overheard in a public location, are lost through theft
of a wallet or purse containing access information, or through carelessness (for
example, writing codes on a piece of paper and improperly discarding them).
Additionally, hackers may use a computer to dial an access code and then
MERLIN LEGEND Communications System Release 6.1

publish the information to other hackers. Substantial charges can accumulate
quickly. It is your responsibility to take appropriate steps to implement the
features properly, evaluate and administer the various restriction levels, and
protect and carefully distribute access codes.
Under applicable tariffs, you will be responsible for payment of toll charges.
Lucent Technologies cannot be responsible for such charges and will not make
any allowance or give any credit resulting from unauthorized access.
To reduce the risk of unauthorized access through Remote Administration and
Maintenance, please observe the following procedures:
■
The System Administration and Maintenance capability of a Hybrid/PBX
or Key system is protected by a password.
— Change the default password immediately.
— Continue to change the password regularly.
— Only give the password to people who need it and impress upon
them the need to keep it secret.
— If anyone who knows the password leaves the company, change
the password immediately.
■
If you have a special telephone line connected to your Hybrid/PBX or
Key system for Remote Administration and Maintenance, you should do
one of the following:
— Unplug the line when it is not being used.
— Install a switch in the line to turn it off when it is not being used.
— Keep the Remote Administration and Maintenance telephone
number secret. Only give it to people who need to know it, and
impress upon them the need to keep it a secret. Do not write the
telephone number on the Hybrid/PBX or Key system, the
connecting equipment, or anywhere else in the system room.

Unit Load Calculation Worksheet
C
If you determine that you need to recalculate the unit load for any carrier, use
the instructions on the following worksheet.
NOTES:
1. You should have a separate copy of the worksheet for each carrier.
2. See ‘‘Unit Loads’’ on page 1-35 for information on recalculating unit
loads.
The 391C1 or 391A3 power supplies have a maximum rating of 75 unit loads. If
your system contains a 391A1 or 391A2 power supply module, and the unit
loads for that carrier will exceed 54, it is recommended that a 391A3 power
supply be installed in the system. Auxiliary Power Units cannot be used with the
391A3 power supply.

Backing Up with a Memory Card
D
A PCMCIA (Personal Computer Memory Card International Association)
interface slot is present on the processor module. The slot is a standard
interface through which information can be added to or obtained from the
system using a memory card. The PCMCIA interface slot accepts one memory
card at a time.
This section covers the following memory card functions:
■
Memory card formatting
■
Restore
■
Backup
■
Automatic backup
Card Types
The types of memory cards are described below. The card type is identified by a
preprinted, color-coded label.
■
Upgrade Card. This card is used for MERLIN LEGEND Communication
System software upgrades. The upgrade can be performed by the
system manager using the memory card and the 0DLQWHQDQFH option on
the SPM Main Menu. This card is identified by an orange label with
black lettering.

■
Translation Card. The backup and restore procedures previously
available to system managers through SPM (using the PC and floppy
disks) can now be performed using the memory card and the new
%DFNXS5HVWRUH option on the System menu. A new automatic backup
feature permits you to set the system to perform automatic backups to
the memory card on a daily or weekly basis. See ‘‘Backup’’ on page D-7
and ‘‘Restore’’ on page D-18 for more information. This card is identified
by a white label with black lettering.
■
Forced Installation. For use by qualified service technicians only, this
card is used when the system software has been corrupted and a
re-installation must be done at the customer site. The use of the card for
forced installation is reserved for emergency situations in which the
system software on the processor module has been damaged. This
card is identified by an orange label with black lettering. In addition,
black stripes are present on the card to distinguish it from an upgrade
card.

If the card is damaged, repeat the backup with a different card. If a backup is in
progress and fails, the system makes two additional attempts at the backup. At
the start of each attempt, a message appears with the percentage of the backup
that is completed. If the backup fails after three attempts, the screen shown
above appears. Repeat the backup procedure using a different file and/or

Restore
Use this procedure to restore system conditions that were backed up onto a
translation memory card. The information in a backup file on the translation card
is copied to the system.
The restore procedure is necessary under the following conditions:
■
System RAM is corrupt.
■
A previously stored set of system conditions is preferred over the current
set.
■
The processor module is replaced.
■
After a System Erase (frigid start) has been performed.
■
The system software has been reinstalled.
The Inspect feature (Inspct or ) is available to view the attributes of the
backup files on the memory card prior to initiating the restore procedure. The
attributes included on the Inspect screen are the filename, the time and day of
the file backup/update, the location of the system programming port, and

If any type of programming is taking place at another extension when you begin
the restore procedure, the restore is canceled and the number of the busy
extension appears on the screen. Repeat the restore procedure when the busy
extension becomes idle.
If a line is busy (incoming call or active call) when you begin the restore
procedure, the restore is canceled and the number of the active line appears on

Modifying the Processor for Key Mode
! CAUTION:
Do not touch the HDR3 header on the processor board; the header is
exposed when the feature module is not installed in the processor. If the
HDR3 header is removed, system programming may be deleted and will
have to be restored.
! On the exposed portion of the processor board, find the header
marked HDR4; it is in the upper-left area.
A shunt is attached to one of the pins on the HDR4 header.
! Remove the shunt from the single header pin; then reinsert it so
that it covers both pins on the header.

To install the control unit’s housing in a Release 2.1 or earlier system, follow the
steps below.
! Lay the front panel(s) face down.
! If you are housing more than one carrier, connect the front panels
together.
a. Line up the arrows.
b. Slide the panels until the semicircles form a complete circle. See
Figure E-2.
! Connect the side panels to the front panel(s) in the same way.
! Pick up the housing and place it on the control unit. If the system
has more than one carrier, make sure you hold the housing only
from the basic carrier side; otherwise, the housing can
disassemble.
a. Line up the wire clips that are attached to the carrier with the
recesses on the outside of the side panels.
b. Push back the panels until the clips hook over the tabs and rest in
the recesses.

This appendix provides detailed information concerning the features and
translations that make up the ISDN Ordering Code (IOC) standardized
capability package “S”, as well as the Multiline Hunt (MLH) feature. The MLH
feature may be provisioned as either the Multiline Hunt Group or Series
Completion feature depending on the CO switch type.
Specific translations are provided for the following switches:
■
Lucent Technologies 5ESS
■
Northern Telecom DMS-100
■
Siemens SSC EWSD
After determining that the local service provider offers National ISDN-1 service,
the information contained in this appendix should be given to the local service
provider if necessary.
NOTE:
The administrative screens shown in this appendix are representative
samples only. The local service provider will need to enter applicable
data (such as the telephone numbers) where necessary. Also note that
the administration covered in this appendix does not take place on the
MERLIN LEGEND Communications System. All administration is
performed by the local service provider on the CO switch.

Switch Translations
For the Lucent Technologies 5ESS switch, Capability Package “S” (2B) includes
alternate voice/circuit-switched data on two B-channels. Data and voice
capabilities include Calling Number Identification. Please note that in order to
have simultaneous calls on the two B-channels, two Directory Numbers (DNs)
must be assigned with this package.
The Lucent Technologies 5ESS switch also provides for alternate voice and
data hunting on one DN via the Series Completion feature.
ISDN Capability Package “S”
The information listed below provides the DN translations that define Capability
Package “S,” and the screens and fields that must be populated.
The information provided shows the translations for one DSL and two DNs. For
multiple DSLs/DNs, the CO will duplicate these screens and enter the
applicable DSL and DN values as needed.

Series Completion Feature Translations
The sample screens shown below illustrate the translations for alternate voice
and data hunting on one main DSL and three DNs forming a linear series
completion group. Voice hunting is provided via Series Completion (Field 87,
SERHLN). Data hunting is provided via Call Forward Data Busy Line
(/CFDBLAC).
The 5ESS limits the number of members of a series completion group to 16
DNs, and the number of lines forwarded via /CFDBLAC to the value specified
on Screen 9, Field 176 (SIMINTRA). This value is currently set to 99 series
completion groups, but can be changed.

restricted, and 64-kbps clear circuit-switched data calls.
address
A coded representation of the destination of data or of the
data’s originating terminal, such as the dialed extension
number assigned to the data terminal. Multiple terminals
on one communications line must each have a unique
address.

ALS
(Automatic Line Selection) Programmed order in which
the system makes outside lines available to a user.
ambiguous
numbering
Numbering of extension ranges, remote access codes, or
other system components that causes conflicts in private
network operations. These numbers can be unique and
still be ambiguous. For example, Extension 441 is
different from Extension 4410. However, for UDP routing
purposes, the two numbers are ambiguous and a call
intended for Extension 4410 is misrouted on the first three
digits sent, to Extension 441. See also unambiguous
numbering.
AMI
(alternate mark inversion) Line coding format in which a
binary one is represented by a positive or negative pulse,
a binary zero is represented by no line signal, and
subsequent binary ones must alternate in polarity;
otherwise, a bipolar violation occurs. AMI is used in the
DS1 interface.
Analog data
station
See modem data station.
analog
transmission
Mode of transmission in which information is represented
in continuously variable physical quantities, such as
amplitude, frequency, phase, or resistance. See also
digital transmission.
ANI
(Automatic Number Identification) Process of
automatically identifying a caller’s billing number and
transmitting that number from the caller’s local central
office to another point on or off the public network.
application
Software and/or hardware that adds functional capabilities
to the system. For example, MERLIN Identifier is an
application that provides caller identification information (if
available in the local area or jurisdiction).
ARS
(Automatic Route Selection) System feature that routes
calls on outside facilities according to the number dialed
and line/trunk availability. To initiate ARS, the user dials a
dial-out code, also called an “ARS access code.”
ASCAP

services provided through an Integrated Digital Services
Network Primary Rate Interface (ISDN-PRI) trunk,
Accunet switched digital service, Megacom, Megacom
800, Software Defined Network (SDN), Multiquest, and
Shared Access for Switch Services (SASS).
asynchronous data
transmission
A method of transmitting a short bitstream of digital data,
such as printable characters represented by a 7- or 8-bit
ASCII code. Each string of data bits is preceded by a start
bit and followed by a stop bit, thus permitting data to be
transmitted at irregular intervals. See also synchronous
data transmission.
AT&T Attendant
Application with equipment that connects to one or more
tip/ring extension jacks and automatically answers
incoming calls with a recorded announcement; directs
calls in response to touch tones.
AT&T Switched

Attendant application that automatically answers incoming
calls with a recorded announcement and directs callers to
a department, an extension, or the system operator.
Automated
Document Delivery
System
See ADDS.
automatic
immediate cycling
Process that occurs in private network when all available
routes for a call specify systems with matching switch
identifiers. The call is routed from the originating system
to the destination system and back to the originating
system in a continuous loop. Switch identifiers labelling
systems must be unique across a private network.

automatic-start tie
trunk
Tie trunk on which incoming calls are routed to an
operator or other designated destination without a start
signal, as soon as the trunk is seized; the destination is
specified during programming. Also called “automatic
ringdown” or “auto-in” tie trunk.
auxiliary power
unit
Device that provides additional power to the system.
B
B8ZS
(bipolar 8 zero substitution) Line-coding format that
encodes a string of eight zeros in a unique binary
sequence to detect bipolar violations.
backup
Procedure for saving a copy of system programming onto
a floppy disk or memory card. See also restore.
bandwidth
Difference, expressed in hertz, between the highest and
lowest frequencies in a range that determines channel
capacity.
barrier code
Password used to limit access to the Remote Access
feature of the system. In a private network, it is especially
important that barrier codes be required for all types of
remote access.
basic carrier
Hardware that holds and connects the processor module,
power supply module, and up to five other modules in the
system. See also expansion carrier.

clock
synchronization
When digital signals are transmitted over a
communications link, the receiving end must be
synchronized with the transmitting end to receive the
digital signals without errors using clock synchronization.
A system synchronizes itself by extracting a timing signal
from an incoming digital stream. All the digital facilities in
a private network operate from a single common clock,
preferably a port connected to a digital PSTN facility on a
hub system or a system that connects two private network
systems. In this case, all digital facilities specify a loop
clock source. One system in a private network may be
specified as a local clock source when no functioning
digital facility in the private network is connected to the
PSTN. All other digital facilities then use this clock and
specify their clock sources as loop. Primary, secondary,
and tertiary clock sources are specified to allow backup
synchronization in the event that the primary source is
out of service.

station
A type of data station that includes a modem as its DCE. It
may also include an MLX telephone for simultaneous
voice and data (MLX voice and modem data station), an
analog multiline telephone (analog voice and modem data
station), or a single-line telephone for dialing only (modem
data-only station). These data stations connect
respectively to MLX, analog, or tip/ring extension jack
modules. They provide analog transmission of data.
modem pool
Pair, or group of pairs, of modems and data modules with
interconnected RS-232 interfaces that converts digital
signals to analog, or analog signals to digital, thereby
allowing users with ISDN terminal adapter data stations to
communicate with users who have analog modem data
stations.
module
Circuit pack in the control unit that provides the physical
jacks for connection of telephones and/or outside
lines/trunks to the communications system. In the name of
a module, the first digit indicates the number of line/trunk
jacks it contains; the last digit indicates the number of
extension jacks it contains. If no letters appear after the
number, a line/trunk module provides loop-start lines or an
extension jack module provides analog or tip/ring jacks.
For example, a 408 GS/LS MLX module contains four
line/trunk jacks and eight digital (MLX) extension jacks,
and provides either loop-start (LS) or ground-start
(GS)trunks.

unambiguous
numbering
The practice of numbering of extension ranges, remote
access codes, or other system components to avoid
routing conflicts in private network or local calling. For
example, Extension 441 is unique when compared to
Extension 4410. However it is ambiguous, because a
system routes as soon as it matches the digits sent for a
call with the digits in a local plan or in a non-local dial plan
extension range. When a caller dials , a system
routes the call to Extension 441 immediately, without
considering the last dialed digit.
