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.

Description/ Recommendation
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 to set the
Supported field to n. Use busyout station extension and release
station extension 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.
No data is detected on Channel B1 during loop back.
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.
The endpoint has responded to the switch activate and deactivate loop
back application messages. Data has been detected on the looped back
channels.
Could not seize the endpoint or B-channels for test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
