ATM-TRK (Circuit Emulation Service Circuit Pack)
Issue 1 May 2002 8-287 555-233-143
Control Channel Loop Test (#52)
The nondestructive Control Channel Loop test is part of the maintenance
subsystem’s Common Port Board Testing feature. The Common Port Board test
sends board vintage queries to a port circuit pack and checks the responses.
CCMS downlink notifications tell the circuit pack which TDM Bus (A or B) carries
the control channel and which carries the touch tones.
The test passes if the port circuit pack responds. The test aborts if the circuit pack
does not respond. The test fails otherwise.

FAIL The ATM circuit pack responded incorrectly.
1. Retry the command up to 3 times at 1-minute intervals.
2. If the test continues to fail, reset the ATM-TRK circuit pack (reset board
UUCSS).
3. If test continues to fail, replace the circuit pack or transceiver.
PASS The ATM-TRK circuit pack is communicating correctly with the software.
0 NO
BOARD Circuit pack not detected.
1. Check the error log for Error 125 (wrong board) or Error 131 (no board),
and correct any errors found.
2. Make sure that the ATM-TRK circuit pack is properly translated and
inserted.
3. Check for Error 1538 (hyperactivity). If hyperactive, run reset board
UUCSS.
4. Run the test again. If it fails, replace the ATM-TRK circuit pack, and retest.
