If you have tested the telephones and the modules in the control unit, you have
isolated the trouble to the trunks or the CO. To isolate the trouble further, follow
the instructions in this chapter to troubleshoot the trunks. If the trouble persists
after following these instructions, the customer should contact the CO and ask a
representative to troubleshoot from that end.
Trunk Errors
The system records errors not only for trunks, but for T1 ports on the module as
well. In some cases, errors occur not because a single port fails, but because
the entire T1 link fails. When this happens, 100D automatic testing activates an
alarm.
Troubleshooting Trunk Problems
Table 5-1
provides a quick guide to troubleshooting trunks.
