Verifying carrier link connections at the remote site
When all the carriers are connected and equipped, all carrier alarm LEDs
might be turned OFF and the signaling across the link works even though
there might be a mismatch in carrier link connection between the local
and remote ends. However, the voice and data connections might not
work due to the scrambling of the time slots, which are assigned to specific
carriers and cannot be used by other carriers. Carrier Test 1 might not
show any errors under these conditions.
Note:
card faceplate ENB/DIS switch is set to DIS. Carrier clocking is enabled
when the switch is set to ENB. Carrier alarms can clear even while the
Local Carrier Interface card is not software enabled when the switch is
set to ENB.
All equipped carriers have been previously connected and configured at
the local site and the carrier circuit ID recorded for each link 0-2. All carrier
facilities (carrier links) should have been installed and tested by the carrier
network provider up to the demarcation point at both ends.
To insure that all equipped carrier links are connected to their
corresponding I/O panel connectors at the remote site, identify, test, and
tag each carrier link individually as described in .
