start or ground start.
Verify Operation
Verify the following after the system is powered up and HDSL communication is synchronized:
1 Observe that the front panel Active indicators are all off and the Fault indicator is off (no calls are in progress).
2 Test circuits for loop start:
a Place an outgoing call for each subscriber circuit provisioned and observe that the Active LED tracks the
progress of the call.
b Place an incoming call for each subscriber circuit provisioned and observe that the Active LED tracks
the progress of the call.
3 Test circuits for ground start, circuits must be provisioned for ground start:
a Place an outgoing call for each subscriber circuit provisioned and observe that the Active LED tracks the
progress of the call.
b Place an incoming call for each subscriber circuit provisioned and observe that the Active LED tracks
the progress of the call.
