Verifying mini-carrier links at the remote site
P0914209 Standard 3.00 April 2000
Installation and configuration
When all the MCR equipment is connected, all mini-carrier alarm LEDs may
be turned OFF and the signaling across the link will work even though there
may be a mismatch in mini-carrier links between the local and remote ends.
However, the voice and data connections may not work due to the scrambling
of the time slots, which are assigned to specific links and cannot be used by
other links. However, Mini-Carrier Test 1 may not show any errors under
these conditions.
All equipped mini-carriers have been previously connected and configured at
the local site and the mini-carrier circuit ID recorded for each link 0-1. All
mini-carrier facilities (mini-carrier links) should have been installed and
tested by the T1 provider up to the demarcation point at both ends.
To insure that all mini-carrier links are connected to their corresponding I/O
cable connectors at the remote site, you must identify, test, and tag each
mini-carrier link individually as follows:
1
Configure all mini-carrier links by executing the S C (Set Configuration)
command. Any unused mini-carrier links must be configured as
"unequipped" to prevent the mini-carrier alarm LED from being
constantly ON. Default parameters should not be changed without good
reason. Execute the D C (Display Configuration) command to verify the
configuration.
2
Identify the circuit ID for carrier 0 at the T1 network demarcation point
and connect the corresponding patch cable to the I/O cable connector
(8-pin modular jack) for carrier 0.
