Procedure 3
Testing the carriers
1 After checking the carrier status report and performance log and
finding that one or more carriers is faulty, proceed to isolate the cause
by testing the carriers using the
TEST (T) command. The screen
displayed by the TEST (T) command is similar to Figure 58.

The
TEST (T)
command allows you to run tests on the local or
remote MCR card, the T1 links, or network equipment. The five
available tests are designed to provide you with the capability to isolate
fault conditions to a specific source. After entering the
TEST (T)
command, you will be prompted to choose which of the five tests you
wish to initiate. The prompt will appear similar to Figure 58.
Tests may be performed once, repeatedly for between 1 and 98
minutes, repeatedly for between 1 and 10 minutes, or continuously
(selected by entering 99 minutes), depending on the test, until the
specified duration passes, or a
STOP TEST (S) command is
entered. Tests will continue for the duration specified even if a failure
occurs. Only a
STOP TEST (S)
command terminates a test
requested to run continuously.
During a test, if an invalid word is received, a failure peg counter
increases by one. This peg counter’s maximum capacity is 65,000. At
the end of the test, the Test Results message will indicate how many
