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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 How to Use This Book Issue 1 August 1998 Page xxii Refer to the following documentation for additional information: ■ 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page xxiii How to Use This Book Some older terms have been replaced with newer terms.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 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 ■ Dracon TS21 or equivalent touch-tone telephone for testing ■ Assorted flathead and Phillips-head screwdrivers ■ Long-nosed and regular pliers MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 On-Site Programming Maintenance Issue 1 August 1998 Page 1-3 ■ Wrist grounding strap ■ Modular cord (D8W-87) ■ Replacement parts recommended by NSAC (if necessary) ■ Programming terminal, MS-DOS PC (Zenith Sport 184) and 355AF Adapter ! 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 On-Site Programming Maintenance Issue 1 August 1998 Page 1-4 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.

Setting Up the PC 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.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 1-10 Using SPM Dialing the System Operator If you do not know the remote access trunk number, dial the number for the 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. ! When you hear the modem tone, hang up. !

Private Networked Systems In Release 6.0 and later systems, where systems are private networked and only one system has public switched networked trunks, you must use this method in order to access SPM on private networked systems. The Remote Access code of the switch you are reaching must be programmed into the non-local dial plan of the system from which you are calling. Remote Access codes must be unique and unambiguous for all private networked systems. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 1-13 Using SPM You dial into the system that has public switched network tandem trunks using Remote Access and then, from that system, reach a private networked switch using Remote Access again. To dial into the system that has public switched networked trunks, follow Steps 2–4 in the previous section, “Dialing the Modem Directly” on page 1–11. If you are already at an extension on a private networked system, skip these steps. Once you are connected to a system in the private network, follow the steps below. ! Start SPM.

Preparation for Hardware Maintenance If you are performing onsite hardware maintenance, first remove the control unit housing (the cover of the control unit), then disconnect the AC power. Removing the Control Unit Housing To remove the control unit’s housing, see Figure 1–5. ■ If you have a MERLIN II Communications System or a MERLIN LEGEND Communications System (Release 2.1 or later): 1. Pull the bottom front of the housing towards you. When it releases, remove it by lifting up as shown in Figure 1–5. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 1-19 Preparation for Hardware Maintenance 2. Remove the top cover from each carrier by pushing straight up from the front. ■ For a MERLIN LEGEND Communications System Release 2.0 or earlier: 1. Pry the clips from the housing on both sides of the control unit; use a screwdriver if they are difficult to remove. 2. Carefully pull the housing towards you. NOTE: If the MERLIN LEGEND (Release 2.0 or earlier) system has more than one carrier, make sure you hold the housing assembly on the basic carrier at the sides; otherwise, the housing may disassemble as the front and side panels are only slotted together.

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 the source of the problem, then hardware should be checked as with non-networked systems. More information about analyzing private network calling problems is included in “Network Calling Problems” on page 5–40. As you become more experienced with maintaining and troubleshooting systems, you will most likely develop your own strategy.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 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.

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: Console Procedure Menu: 0DLQWHQDQFH→6ORW→Dial →'HPDQG 7HVW→6\VWHP(UDVH (Line 5 of the display, left button)→6\VWHP(UDVH→<HV PC Procedure →→Type →→→→ Considerations 6\VWHP(UDVH is not displayed on the MLX-20L status display.

If you want onsite printouts from the SMDR printer, make sure you change the option. To change the printer option, see System Programming and Maintenance (SPM) for information about the Print Opts option on the SPM Main Menu. For more information about System Erase, see “See “Processor Problems” on page 4–12.. Isolating the Trouble You can isolate any problem to one of the following areas: ■ Telephone ■ Control unit MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Maintenance Strategy Issue 1 August 1998 Page 1-27 ■ Central office ■ 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 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Maintenance Strategy 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Maintenance Strategy Issue 1 August 1998 Page 1-30 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Maintenance Strategy Issue 1 August 1998 Page 1-31 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 1-32 Maintenance Strategy 2. Refresh the Message Waiting lights on the systems on the VMS on the private network. NOTE: Multiple refreshes across a private network, using tandem tie lines, can cause congestion and delayed refresh time, it is advisable to coordinate refresh operations in a private network to send only one refresh message.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Unit Loads Issue 1 August 1998 Page 1-38 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 Issue 1 August 1998 August 1998 Error Logs Page 2-1 Error Logs, Access Logs, and System Inventory 2 2 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, MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 2-2 Error Logs as shown in Table 2–1.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 3-2 Fixing Telephone Problems 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. Fixing Telephone Problems If a reported telephone problem matches any symptom described in Table 3–1, refer to the referenced section of this chapter. Table 3–1.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Fixing Telephone Problems Issue 1 August 1998 Page 3-4 ! 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Fixing Telephone Problems Page 3-5 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. Call Forwarding Problems Call Forwarding problems usually occur when someone activates Call Forwarding unintentionally, resulting in a user receiving other users’ calls. Cancel the Call Forwarding feature (for the receiving telephone): ■ On multiline telephones, press the Feature button and dial . MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 MLX Telephone Tests ■ Issue 1 August 1998 Page 3-6 On single-line telephones, pick up the handset, dial , and then hang up. NOTE: You can cancel Call Forwarding from the receiving telephone or from the forwarding telephone, providing that you know the number. MLX Telephone Tests If the LEDs, ringer, buttons, switchhook, or display appear not to be working, try the steps below. ! Pick up the handset. ! When you hear dial tone, press (the feature access code). The telephone enters test mode. For some tests, this means the LEDs turn on; for others, it means the phone starts ringing. ■ This test connects a test tone to the B-channel and sends a repeated ring burst to the telephone. ■ On an MLX telephone with a DSS attached, all LEDs light and the phone rings throughout the test. ■ On an MLX display telephone, the display blanks out and is replaced with a grid of small dots. ! Press each line/feature button (two LEDs each). The red and green LEDs should toggle on and off. ! Press each fixed-feature button that has an LED (Feature, HFAI, Mute, and Speaker). Each LED should toggle on and off. NOTE: Mute and Speaker LEDs may not toggle consistently because they are managed by the control unit and the telephone.

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 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 3-9 System Requirements for Touch-Tone Receivers calling group queue, requires TTRs for primary and secondary delay announcement devices that present the option to callers. Table 3–3. TTRs Required by VMS/AA Number of VMS Ports Number of TTRs Required 1 1 2 1 3 2 4 2 6 3 8 4 12* 6* 18 8 *If a 12-port MERLIN LEGEND Enhanced Service Center is used, 8 TTRs are required. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 3-10 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. Table 3–4.

MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Module Problems Issue 1 August 1998 Page 4-34 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.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Module Problems Issue 1 August 1998 Page 4-38 ! For MLX modules (008 MLX and 408 GS/LS-MLX) and 800 NI-BRI modules, continue with the B-Channel Loopback test. See “B-Channel Loopback Test” on page 4–57.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 4-39 Module Problems — 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. Menu: 0DLQWHQDQFH→6ORW→6WDWXV Once you finish testing a module, you must restore it. Restoring a module terminates the Busy-out or Reset condition. See ‘‘Restore’’ on page 4-45 for instructions.

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 August 1998 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 Maintenance and Troubleshooting 555-661-140 Module Problems Issue 1 August 1998 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 4-64 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 4-65 Module Problems Firmware on this circuit module can be upgraded or reinstalled with an Upgrade memory card.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 800 NI-BRI Module Problems Issue 1 August 1998 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.

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. 100D Module Error Events This procedure allows you to check for 100D module errors.

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.

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 Computer Telephony Integration (CTI) Link Problems Issue 1 August 1998 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 Maintenance and Troubleshooting 555-661-140 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.

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.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Page 5-2 Trunk Errors Table 5–1. Issue 1 August 1998 Troubleshooting Trunk Symptoms Symptom Section Incoming calls not being received Incoming Trunk Problems, page 5-4 Cannot make outgoing calls Outgoing Trunk Problems, page 5-3 General trunk problems Manual Correction of Trunk Problems, page 5-2 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). MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 5-3 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 5-4 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Trunk Errors Page 5-5 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 ■ Digital Trunks MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Trunk Errors Issue 1 August 1998 Page 5-6 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 Maintenance and Troubleshooting 555-661-140 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. Maintenance-Busy Programming You can select 0DLQWHQDQFH%XV\ as a system programming option. If you do, there is also a menu selection to include tie trunks. Maintenance-Busy Status See “Checking Ports” below for information about maintenance-busy status. Checking Ports You perform the following procedures from the maintenance terminal.

MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Private Network Calling Problems Issue 1 August 1998 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 Maintenance and Troubleshooting 555-661-140 Private Network Calling Problems Issue 1 August 1998 Page 5-42 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 5-43 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.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Private Network Calling Problems Issue 1 August 1998 Page 5-45 ! 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 Maintenance and Troubleshooting 555-661-140 Private Network Calling Problems Issue 1 August 1998 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Page 5-51 Private Network Calling Problems ■ 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.

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. 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 5-55 ■ 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Call to Non-Local Extension: Warble Tone (Error Tone) 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Calls to Non-Local Extensions: Unexpected Busy Tone Issue 1 August 1998 Page 5-58 ■ 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. 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 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Call to Non-Local Extension Reaches Wrong Extension Issue 1 August 1998 Page 5-59 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Call to Non-Local Extension: Message from CO Issue 1 August 1998 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Transfer to Non-Local Extension Not Completed Issue 1 August 1998 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 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 Maintenance and Troubleshooting 555-661-140 DID Calls Not Completed Issue 1 August 1998 Page 5-64 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Callback Does Not Work Issue 1 August 1998 Page 5-66 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. ■ 1–20 = trunk connected to a MERLIN LEGEND Communications System that is more than 200 miles away ■ 21–40 = trunk connected to a MERLIN LEGEND Communications System that is within 200 miles ■ 41–50 = trunk connected to a system that is not a MERLIN LEGEND Communications System (for example, a DEFINITY ECS communications system) and is more than 200 miles away MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Private Network Call Transmission Level (Volume) Too Low or Too High ■ Issue 1 August 1998 Page 5-67 51–60 = trunk connected to a system that is not a MERLIN LEGEND Communications System (for example, a DEFINITY ProLogix Solutions communications system) and is within 200 miles 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 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Private Network Call Transmission Level (Volume) Too Low or Too High Page 5-68 programmed on the switches on the other end of the tandem trunk. Systems B and C are linked by trunks whose identifiers indicate distant systems. 21 System A 22 tandem trunk NY, NY System B 03 02 tandem trunk Queens, NY System C Atlanta, GA The example below shows programming that would be incorrect in the same private network. The link between Systems A and B has mismatched identifiers, because System B specifies that System A is more than 200 miles away. System C incorrectly specifies System B as a non-MERLIN LEGEND Communications System. System A NY, NY 01 X 21 tandem trunk System B 42 Queens, NY 03 X tandem trunk System C Atlanta, GA 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 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 MLX Displays: Private Network Call Display Problems Issue 1 August 1998 Page 5-69 situation occurs frequently. Contact your Lucent Technologies representative or Local Authorized Dealer for instructions. If the problem is not solved with the above instructions, call the Lucent Technologies Helpline at 1 800 628-2888; consultation charges may apply. 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 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 PassageWay Call Display Problems Issue 1 August 1998 Page 5-70 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 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 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Station Message Detail Recording (SMDR) Reports Do Not Include Calls Page 5-73 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 properly and has an in-service facility connected to it. If this does not solve or explain the problem, call the Lucent Technologies 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. System A PSTN IN 555-1234 OUT 555-1234 System B IN 1234 OUT 4+1234 System C IN 41234 Ext. 41234 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 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Conclusion of Hardware Maintenance Issue 1 August 1998 Page 5-74 are in the same time zone.

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 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Security of Your System: Preventing Toll Fraud Issue 1 August 1998 Page A-12 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Toll Fraud Prevention ■ Issue 1 August 1998 Page A-13 Use the longest-length barrier codes possible, following the guidelines for passwords. (See‘‘Choosing Passwords’’ on page A-24) 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). MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Toll Fraud Prevention ■ Issue 1 August 1998 Page A-15 Customers should also take advantage of Lucent Technologies monitoring services and devices, such as the NetPROTECTSM family of 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Other Security Hints Issue 1 August 1998 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Other Security Hints Page A-22 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 MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Issue 1 August 1998 Other Security Hints Page A-23 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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Limited Warranty and Limitation of Liability Issue 1 August 1998 Page A-25 ■ 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”).

THIS PARAGRAPH SHALL SURVIVE FAILURE OF AN EXCLUSIVE REMEDY. 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 Maintenance and Troubleshooting 555-661-140 Remote Administration and Maintenance Issue 1 August 1998 Page A-28 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.

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.

Up to two DSSs (one DSS per MLX-28D or MLX-20L console) can be powered from each control unit carrier. For example, a 3-carrier system can have 6 system operator positions, each with one DSS powered from the control unit. ■ If the unit load for slots five and six is less than or equal to 27, power is sufficient for the carrier. ■ If the unit load for slots five and six is more than 27, continue to Step 9. 9. Try to exchange modules between carriers to reduce the unit loads for slots 5 and 6 through 27. The 100D, 400 (LS), 400 GS/LS/TTR, 800 GS/LS-ID, 800, 800 NI-BRI, and 800 GS/LS modules have unit loads of 0.0. Repeat Steps 1 through 8 to recalculate unit loads for new configurations. ■ If the exchange reduces the unit load for slots five and six through 27 or less, power is sufficient. ■ If the exchange does not reduce the unit loads for slots 5 and 6 through 27, install wall power units for the appropriate number of telephones to reduce the unit load to 27. NOTE: Empty slots are not permitted between modules.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Card Types Issue 1 August 1998 Page D-2 ■ 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. Figure D-1 shows a sample Translation card.

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. MERLIN LEGEND Communications System Release 6.1 Maintenance and Troubleshooting 555-661-140 Lucent Technologies 5ESS Switch Translations Issue 1 August 1998 Page F-2 Lucent Technologies 5ESS 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.
