Looparound and Conference Circuit Test (#33)
This test checks the reflective loop and conference abilities of a CO port circuit.
The test uses 404-, 1004-, and 2804-Hz tones. Each tone is transmitted
separately through the loop and checked.

Result Description / Recommendation
ABORT Could not allocate system resources to run this test.
7 ABORT Conference Circuit test aborted.
1000 ABORT System resources required to run this test are not available. The port may be
busy with a valid call.
1. Enter display port UUCSSpp to determine the trunk group/member
number of the port. Use the status trunk command to determine the
service state of the port. If the port is unavailable, wait until it is idle before
testing.
2. If the port status is idle, then retry the command at 1-minute intervals up to
5 times.
1004 ABORT The port has been seized by a user for a valid call. Use the status trunk
command to determine when the port is available for testing.
1. Retry the command at 1-minute intervals up to 5 times.
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
7 FAIL 1. Check for errors on TONE-BD or TONE-PT.
2. If the Reflective Looparound test fails for every port on a circuit pack, a -5V
power problem is indicated. If a TN736 or TN752 power unit circuit pack is
present, check the circuit pack for a red LED. If the red LED is on, then
replace the appropriate power unit circuit pack. If neither the TN736 nor
the TN752 Power Unit circuit pack is present, then the OLS631DB AC
power unit may be defective. The system may contain a TN736 or TN752
power unit circuit pack or an OLS631DB AC power unit, but not both. See
‘‘CARR-POW (Carrier Power Supply)’’ on page 8-393.
3. Rerun the test.
4. If the test fails again, replace the circuit pack.
PASS CO Trunk Looparound and Conference test is successful. User-reported
troubles on this port should be investigated by using other port tests and by
examining trunk or external wiring.
