Note: In the CALS column for carrier 1, it shows that carrier
alarm status has alarm level 1 and no new data is allowed.
Testing the carriers using the T command
After checking the carrier status report and performance log, if one or more
carriers are faulty, isolate the cause by testing the carriers using the T
(test) command.
There are two types of tests that can be performed using the T command.
These are on-line tests and off-line tests.
On-line carrier test The on-line carrier test (Test #1) is end-to-end
carrier test performed without affecting the system performance
and determines that a failure exists but cannot pinpoint the faulty
component. Perform Test #1 on a known good carrier to switch signaling
communication over this carrier. Don't test a carrier in alarm condition
using Test #1, it may disrupt traffic for the duration of the test. A better
approach is to disable the carrier you wish to test and perform one of the
other tests to determine where the problem lies.
Disabling a carrier will prevent any new calls being placed over that carrier;
however, it will not effect calls in progress over the disabled carrier.
Performing Test #2 or #3 on a carrier will interrupt any calls in progress
over that carrier for the duration of the test.
Off-line carrier tests The off-line carrier tests (Tests #2, #3, #4, and
#5) isolate the failure to a field-replaceable unit. These tests are usually
performed on carriers that are not carrying traffic. The user must specify
the carrier to be tested and the duration of the test.
Test #2 tests the near-end card by looping back the carrier link side and
verifies if the card is good.
