The carrier links are now connected correctly. This will be further
established during acceptance testing when the actual calls are made to
verify the voice and data transmission across the carrier links.

Before you conclude the installation and configuration of the MCR,
re-verify the configuration parameters and make sure that they are set
properly.
To display the configuration parameters, execute the D C command on the
MMI terminal. See
78) for an example of what the MMI terminal may display:
Parameter values explanation:
•
messages are enabled.
•
Alarm Threshold — Number of bipolar violations. E
or 1 error in 1 million bits, E
and E-4 represents 10
•
Threshold Duration — Mini-Carrier signal monitoring duration (1
second to 3600 seconds) to detect bit error rate (CRC and BIPV)
show the type of carrier alarm on carrier 0, and the D S D
command cannot retrieve the distant-end status.
•
If the LED for carrier 0 RMI (near-end) is OFF but the RMI
and the LMI cannot establish communication due to a carrier
alarm condition on the LMI (distant-end), the D S command
will show "No Alarm" on carrier 0 on the RMI (near-end), and
the D S D command cannot retrieve the far-end status.
Disconnect the patch cable from the I/O cable connector for
carrier 0 that was just tested and repeat steps 1 through 5 for
carrier 1 as equipped before proceeding to step 6.
Any carrier faults must be isolated and corrected. In case of
mismatched carriers, the patch cables must be traced to the
demarcation point at each end, and the carrier circuit IDs verified
at both ends, to determine which end of the carrier has been
mis-wired or incorrectly identified.
After all carriers have been identified and labeled at the I/O
cable connectors, they should all be plugged into the proper I/O
cable connectors for the RMI and tested individually using the
MMI Carrier Test 3 (Remote Loopback). Refer to
carriers" (page 109).
