Introduction 1 The purpose of maintenance is to detect, report, and clear problems quickly with minimal disruption of service, The system attempts to isolate each problem to a single replaceable unit, whenever possible, by running automatic tests. Errors that it cannot automatically correct are usually recorded in error logs. Most troubleshooting r[...]

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 connect a PC to the control unit, you need a 355AF adapter and a D8W-87 cord. NOTE: On-site programming maintenance is preferred if it is fe[...]

On-Site Programming Maintenance On-Site Programming Maintenance You can perform on-site maintenance with an MLX-20L console or a PC with SPM software.

Maintenance Strategy Maintenance Strategy The maintenance strategy presented in this section is only a guideline, not a fixed procedure. Refer to Figure 1-7 whenever you are uncertain as to how to proceed. As you become more experienced with maintaining and troubleshooting the system, you will most likely develop your own strategy. User or AT&T[...]

Maintenance Strategy Trouble Reports System trouble can be reported in two ways: ■ By users ■ By system alarms (permanent errors) Automatic Tests The system performs ongoing maintenance automatically by running tests that : Monitor the status of equipment. Audit operations consistency. Detect hardware malfunctions. Without disrupting normal ser[...]

Maintenance Strategy If a software installation or upgrade is taking place, a blinking character is displayed to indicate the status of the procedure. See "Forced Installation of System Software” in Chapter 4 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 [...]

Maintenance Strategy 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. Considerations ■ ■ Power interruptions of less than 100 ms usually do not affect the system. Warm starts may cause telephones without incoming[...]

Maintenance Strategy Frigid Start (System Erase) CAUTION: All system programming is erased. When you perform a frigid start (System Erase), all calls are dropped, and the system configuration information is erased. All system memory must be reinitialized, including system programming. Then the entire system must be rebooted. To perform a frigid sta[...]

Maintenance Strategy Isolating the Trouble You can isolate any problem to one of the following areas: ■ Telephone ■ Control unit ■ Central office NOTE: 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[...]

Maintenance Strategy 1 Check the permanent errors. 2 If errors still exist, check the transient errors. 3 Check the last 10 errors whenever you want to review the 10 most recently recorded errors-either permanent or transient. Trouble Accessing the Error Logs 1 2 3 4 If you cannot access the error logs, or if the system is inoperable, use the follo[...]

See “Access Log for Maintenance and System Programming” in Chapter 2 for additional information. See System Programming for information about system programming and the Inspect function. Check the P[...]

Unit Loads Check the Trunks Troubleshoot the trunks that are connected to the control unit. See Chapter 5, “Central Office Problems.” Check the Central Office If the error logs indicate the central office as the source of the problem, and you have resolved all other possible causes, notify the customer that they should call the central office a[...]

Unit Loads 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. Checking Unit Loads In the event of maintenance or equipment changes, recalculate the uni[...]

Unit Loads Auxiliary Power Units The power supply provides 54 unit loads (102.6 watts) to each carrier. If the unit load requirement for a carrier exceeds 54 (102.6 watts), an auxiliary power unit is needed to allow that carrier to support an additional 27 unit loads (51.3 watts). CAUTION: Running the system with more than 54 unit loads (102.6 watt[...]
