MTP Analog Loop Around Test (#103)

This test is a nondestructive test. The test does an on-board loop around by using
the MTPINADS channel. Test data is sent through the on-board modem out
toward the INADS trunk. The data is looped around before the actual trunk, and it
comes back into the on-board modem. The data is then verified for integrity.
NOTE:
The test does not send any data onto the INADS trunk. However, in order to
pass, the test does require the trunk to be present.

Issue 5 October 2002
Description/ Recommendation
MTP reported test failure. No loop current detected.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2. If the test continues to fail, examine the INADS trunk for connectivity,
and manually check for loop current.
3. If there is no INADS trunk, this test should be disabled. To disable the
test, issue the change system-parameters maintenance command,
and change the Test Remote Access Port field to "n." If this test is failing
on the Standby SPE, issue the refresh spe-standby command, and
rerun the test.
4. If the INADS trunk checks out okay, but the test still fails, check the
backplane connector wiring.
5. If the backplane wiring checks out okay, replace the Processor circuit
pack at your earliest convenience.
MTP detected a loop current on the remote access port.
1. If the system cannot call INADS, or INADS cannot contact the system,
check with the local Central Office for problems with the INADS trunk,
and verify that the INADS number is correct.
Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
System could not determine if the testing of the INADS port is administered.
1. Enter the change system-parameters maintenance command. Verify
that the "Test Remote Access Port?" field is set to "y."
2. Retry the command at 1-minute intervals a maximum of 5 times.
The remote access port is busy. INADS is probably dialed into the switch.
1. If INADS is dialed in, the INADS trunk is working. There is no need to run
the test.
