●
Maintenance/Far-End (MTC/FE)
This state is reached when the far-end terminal adapter does not respond to messages sent
over the signaling link for a particular port within a certain amount of time. This state is
different from OOS/FE since the signaling link must have initially been up and the B
channels in service. The switch will periodically send messages to the far-end terminal
adapter to try to negotiate the port (B channel) into service. The port is unusable for
outgoing calls to the terminal adapter but will service incoming call requests from the far
end. Other ports of the PRI endpoint can still to place outgoing calls to the terminal adapter.
Transitions into MTC/FE do not drop stable calls. If the service state changes from
in-service to MTC/FE, stable calls are unaffected.

Maintenance/Near-End (MTC/NE)
Use busyout, test port l or test pri-endpoint l to busy out the signaling link
(SYS-LINK). Transitions into MTC/NE do not drop stable calls. The busyout link
lnk-no command does not drop stable wideband calls. In this state, the B channel is not
lnk-no command does not drop stable wideband calls. In this state, the B channel is not
usable for new incoming calls to the switch or new outgoing calls to the terminal adapter.
●
Pending States (PEND)
If the near end is expecting a timed response from the far end for a request to change the
service state of a port, a pending state is in effect. For example, if the port is out-of-service/
far-end and an in-service message was sent to the far end, then the service state of the port
is OOS/FE-PEND/INS meaning out-of-service/far-end, pending/in-service. The service
state will reflect this pending state until the far end responds or the timer expires.
