Configuring the Carrier Remote IPE
129
parameters should not be changed unless you have a good
reason for changing them.
Execute the
D C
(Display Configuration) command to verify the
configuration.
2
Identify the circuit ID for carrier #0 at the carrier network
demarcation point and connect the corresponding patch cable to
the I/O panel connector (8-pin modular jack) for carrier #0.
3
Observe the carrier alarm LEDs on the faceplate of the Remote
Carrier Interface card.
Initially carrier alarm LEDs for all equipped carrier links should
be ON due to Loss-of-Signal. The LED for carrier #0 should be
turned OFF approximately 10 seconds after the patch cable
for the selected carrier #0 is plugged into the Remote Carrier
Interface card I/O panel connector for carrier #0.
If a good quality signal is received by both the Remote Carrier
Interface card and the Local Carrier Interface card on carrier #0,
the link is installed in the appropriate I/O panel connectors at
both ends. If the connection is mismatched (carrier #0 at one
end connects to carrier #1 or #2 connectors at the other end),
the alarm LED remains ON.
The LED also remains ON if there is a carrier alarm on the
Remote Carrier Interface card (near end); however, the LED is
turned OFF if there is no carrier alarm on the Remote Carrier
Interface card (near end) and communication cannot be
established across the link due to alarm on the Local Carrier
Interface card (distant end).
Distant end carrier alarms cause the near end LED to turn ON
only if the Remote Carrier Interface card and Local Carrier
Interface card can communicate.
4
Test the carrier 0 link by executing the carrier status commands
(
D S
- display carrier status and
D S D
-display carrier stratus
distant) using the MMI terminal.
Compare the carrier status on both the Remote Carrier Interface
card (near end) and the Local Carrier Interface card (far end).
Refer to
“Configuring the carriers” (page 122)
to see the displays
of these two MMI commands. There are four possible conditions:
a
If the LED for carrier #0 is OFF and the Remote Carrier
Interface card and Local Carrier Interface card have establish
signaling communication, both ends will show "No Alarm" for
carrier #0 and "Loss of Signal" for carrier #1 and carrier #2.
No mismatch.
b If the LED for carrier #0 stays ON due to a mismatch, the
Local Carrier Interface card (far end) will show "Loss of
Signal" for carrier #0 and "No Alarm" for carrier #1 and carrier
#2.
