MAINTENANCE GENERAL MAINTENANCE INFORMATION System Errors and Alarms During periodic testing, a maintenance audit could detect a system error that automatically generates an error record. Depending on severity, the error record is stored in one of following three tables in the Error Log: ● Permanent System Alarms ● Transient System Errors ● M[...]

MAINTENANCE Attendant Console LED A lighted green Alarm LED on the console indicates the presence of a Permanent System Alarm. The LED flashes with each new alarm. The attendant can press the associated button to cause the LED to light steadily. A lighted red Alarm LED indicates a barrier code violation. Power Supply LED A lighted green LED on the [...]

MAINTENANCE Using RIMS, the remote administrator can initialize translations after the switch itself is installed. As long as there is no hardware change, the remote administrator can do ongoing administration without having to visit the customer’s site. Similarly, to trouble-shoot a problem, a technician can call the RIMS port and check the Erro[...]

MAINTENANCE Administration Requirements For a RIMS call to be made during initialization, at least one voice station and one trunk must be translated. A cold start with defaults provides these translations. The RIMS transfer code (*1 00) can be assigned to a Repertory Dialing feature button on a multiline voice terminal. If the Remote Access featur[...]

MAINTENANCE MAINTENANCE STRATEGY Fault isolation is the cornerstone of the System 25 maintenance strategy. Maintenance activity isolates faults to one (or more) repairable or replaceable maintenance units. Equipment should be tested in the following order: 1. 2. 3. 4. 5. 6. Terminal equipment Station wiring Port circuit packs (CPs) Common control c[...]

MAINTENANCE Sometimes, faults recorded in the error log and user-reported troubles will exist at the same time. The logged faults should always be cleared first, if possible. This procedure often clears the user-reported troubles without any additional maintenance. Clearing the most serious logged fault may clear some or all of the other faults. De[...]

MAINTENANCE Common Control Problems Common Control circuitry is difficult to troubleshoot. The system must be powered down before any of these CPs are replaced. Before powering the system down, save translations to tape (see “Using the Digital Tape Unit”). Other repair procedures may also require the system to be powered down. After removing a [...]

MAINTENANCE Station, Wiring, and Trunk Problems If the system indicates that a fault is with a station, or if a user complaint indicates a station problem, the trouble must be isolated to the station itself or to the wiring between the cabinet or station interconnect panel and the station. The station wiring, particularly the mounting cord, should [...]

MAINTENANCE USING THE DIGITAL TAPE UNIT The Model DC4 Digital Tape Unit (DTU) or equivalent is extremely important in system maintenance.
