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 63 "TEST screen" (page
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 failures, if any, occurred during the test. If the
counter reaches 65,000, it will remain there until reset.
Test 1 listed above is a test that can be run while the MCR
Circuit Pack is on line. The On-line Carrier test will indicate
whether or not there is a failure, but does not indicate where the
failure has occurred.
Tests 2 through 4 are off-line diagnostic tests and must be run
when the MCR Circuit Pack on which the tests are being run has
been disabled, since the testing will interfere with call traffic. By
using the off-line tests in tandem, you will be able to isolate a
