9-1180PE-BCHL (PRI Endpoint Port)
9
This is the state of the port when a hardware failure exists on the signali ng
link, the NPE Crosstalk Test fails, or when the port is busied out by
command. In this state, the p ort is unusable for calls c oming in to the
switch or going out to the terminal ad apter, although other p orts in the PRI
endpoint can still be used for incoming and outgoing calls. No messages
are sent to the far-end terminal adap ter until the signaling link comes back
into service or the port is released by command.
■Maintenance/Far-End (MTC/FE)
This state is reached when the far-end terminal adapter does not resp ond
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 b een up and the B-Chan nels in service.
The switch will periodically se nd messages to the far-end termi nal adapter
to try to negotiate the port (B-c hannel) into service. The port is unusa ble
for outgoing calls to the ter minal adapter but will service incoming c all
requests from the far-end. Other ports of the PRI endp oint can still to place
outgoing calls to the ter minal 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)
The signaling link (SYS-LINK) is busied out by the busyout, test port l or
test pri-endpoint l commands. Transitions into MTC/NE do not drop
stable calls. The busyout link lnk-no command does not drop stab le
wideband cal ls. In this state, the B-Channel is not usable for new incoming
calls to the switch or new outg oing calls to the terminal ad apter.
■Pending States (PEND)
If the near-end is expecting a timed response from the far-end for a
request to change the servic e 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 se rvice state of the port is
OOS/FE-PEND/INS meaning out-of-service/far-end , pending/in-servic e.
The service state will reflect this pend ing state until the far-end resp onds
or the timer expires.
