adjunct. If these attempts fail, the problem should be escalated because
re-engineering of the traffic on the PKT-CTRL, signaling link, or adjunct
may be necessary.
i. This error indicates a problem with Layer 2 over the D-channel between
the switch and the endpoint. When this error occurs, an alarm is raised
against the station or adjunct. Execute the test station extension short
command and pay particular attention to the results of the BRI XID Test
(#628). If this test fails, follow the repair procedure for Test #628.
j. This error indicates a problem with the B-channel connection between the
switch and the endpoint. When this error occurs, a warning alarm is raised
against the endpoint. Execute the test station extension l command, and
pay particular attention to the results of the BRI Remote Loop Back Test
(#627). If this test fails, follow the repair procedure for Test #627.
k. This error occurs whenever the point-to-point signaling link to the endpoint
goes down (except when it goes down because either the PKT-CTRL or
the PKT-BUS has failed or has been busied out by system technician).
When this error occurs, an alarm is raised against the endpoint or adjunct.
Execute the test station extension short command and pay particular
attention to the results of the Signaling Link Status Test (#626). If this test
fails, follow the repair procedure for Test #626. The alarm is retired when
the signaling link is reestablished to the endpoint or adjunct.
l. Certain ASAI protocol-specific cause codes are logged by switch
software. The cause code can be determined from the following formula:
If the error type is greater than 3712, then the ASAI cause code is equal to
the error type minus 3712. This code was sent to the adjunct by the
switch.
If the error type is less than 3712, then the ASAI cause code is equal to the
error type minus 3584. This code was sent to the switch by the adjunct.
A description of the various ASAI cause values is contained in the Table
10-64. This table also contains recommended system technician actions
associated with the cause value. Further information can also be found in
the AT&T ASAI Specification (AT&T PUB 288-500-03). In addition, the Aux
Data field of the Error Log entry contains additional diagnostic information.
