2.4.7 Fault (J7)
The fault connector is used to provide Form C contact closures for fault reporting. The
three Form C summary fault contacts are:
•
Transmit faults
•
Receive faults
•
Common equipment faults
Refer to Chapter 4 for a discussion of faults monitored. To obtain a system summary
fault, connect all the Form C contacts in parallel
The fault interface connection is a 9-pin female D connector located on the rear panel of
the modem. Screw locks are provided for mechanical security on the mating connector.
