Communication Manager Maintenance Object Repair Procedures
e. Error Type 257: this is an inline error and can only be resolved over time. This error
indicates that ringing voltage is absent.
For media modules: If not resolved over time, replace the media module.
For circuit packs:
● If only 1 analog circuit pack in the system has this problem, replace the circuit
pack.
● If only analog circuit packs on a particular carrier have this error, the ringing
generator may not be connected to this carrier.
● If analog circuit packs on many carriers have this error, it is probably a problem
with the ringing generator.
f. Error Type 513:Test #48 can cause some terminal equipment to ring briefly during daily
maintenance. If this disturbs the customer or the terminal equipment, disable it by setting
the Tests field on the change station extension form to n. In some software
releases, this also disables Tests #6, 7, 161, and 35.
