TL-130200-1001Fault Code 15Description: Tl AlarmThe system monitors the TlS (Tl Supervision Circuit Card) for hardware alarms. This fault indicates that the data framing of a span has failed for 36 ms, the power has failed in the local office terminating equipment, or synchronization has been lost at the distant office for 1.2 seconds.

Complete the following steps: - Remove and replace FDC, FB-15278-A, in X/l 0 (check strapping). - If LOC lamp remains lit, repeat preceding procedure by replacing sequentially all Tl cards until the fault is cleared (check strapping): pcBSLOT TlB2X/18 TlSX/16 SILX/l 4 LCM X/l 2 4.REM lamp lit indicates problem exists at remote location (fault code D, register value is 01). Report condition to remote end personnel. 5.RPF lamp lit indicates power has failed at remote location (fault code D, register value is 01). Report condition to remote end personnel. 6.Check with remote end personnel to ensure that Tl alarm is not a temporary trunk failure condition. 81875210

TL-130200-1001Fault Code 16Description: 10 ms Stopped FailureThe system performs checks to ensure that the 10 ms interrupt is operating. A time check is performed to see if the background scheduler has been interrupted to perform foreground scheduler tasks. If the average time is too short, it is assumed that the interrupt is not operating.
