BRI XID Test (#628)
This test checks the D-channel connection between the SPE and the endpoint or
adjunct.
In this test, a D-channel XID frame is sent to the endpoint or adjunct over the
point-to-point signaling link. The test passes if the endpoint or adjunct responds
with a Layer 2 XID-RESPONSE frame.
This test must be administered to not run in the station administration form for
ports on a TN2208.
2000 FAIL No loop back activation or deactivation response is received from the
endpoint.
1. Consult the endpoint documentation to determine if ISDN-BRI
Management and Maintenance Procedures are supported. If not
supported, use change station extension command to change the
MIMs Supported? field to n. Use the busyout station extension
and release station extension commands to busyout and release the
endpoint to resolve any endpoint alarms resulting from failure of this
test.
2. If the endpoint supports these procedures and the test continues to
fail, assume the endpoint is defective and replace it.
2071 FAIL No data is detected on Channel B1 during loop back.
2072 FAIL No data is detected on Channel B2 during loop back.
1. Replace the endpoint and repeat test.
2. If test continues to fail, check the wiring between the endpoint and the
switch and repeat the test.
PASS The endpoint has responded to the switch activate and deactivate loop
back application messages. Data has been detected on the looped back
channels.
1000 ABORT Could not seize the endpoint or B-channels for test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
