M/T-ANL (Maintenance/Test Analog Port)
Issue 1 May 2002
8-827555-233-142
Clear Error Counters (#270)
The ports on the Maintenance/Test circuit pack continually run self-tests,
whenever the port is idle. The Angel uses a counter so that the Background
Maintenance Failure message is only sent uplink once (this keeps a failed
port/circuit pack from flooding the SPE with a string of messages). Many circuit
packs have counters in the Angel firmware. These counters are used so that
Control Channel Message Set (CCMS) messages are not continuously sent
uplink. Using this method, the message will be sent once, when the counter
reaches some preset threshold, and then not sent again until the counter is
cleared. This test is used to clear the counter, so that if the port continues to fail
during or after SPE-demanded testing, the Angel will send a message to indicate
that fact.
This test is only used to send a message to the Angel on the Maintenance/Test
circuit pack. Therefore, this test should never abort or fail.
7 FAIL Conference test failed on the primary information channel.
1. Run the circuit pack tests to check the Tone-Clock (TONE-BD) circuit pack
and the Tone Detector circuit pack via the test board UUCSS command.
2. Resolve any problems that are detected on the Tone-Clock (TONE-BD)
circuit pack or Tone Detector circuit pack. See the section on Tone
Generator circuit pack.
3. If the Tone-Clock and Tone Detector circuit packs are functioning properly,
and the test still fails, replace the Maintenance/Test circuit pack.
14 FAIL The primary information channel is not transmitting properly. User may not
notice any interruption in service or may not be able to use this port.
1. Run the circuit pack tests to check the Tone Generator circuit pack and the
Tone Detector circuit pack using test board UUCSS.
2. Resolve any problems that are detected on the Tone Generator circuit pack
or Tone Detector circuit pack. See the section on Tone Generator circuit
pack.
3. If the Tone Generator and Tone Detector circuit packs are functioning
properly, and the test still fails, replace the Maintenance/Test circuit pack.
PASS The Maintenance/Test analog port analog trunk testing capability is operating
correctly.
