f. This error occurs when the ASAI-EPT message is not transmitted because
the PKT-CTRL (packet control circuit pack) transmit buffers are
exhausted. Frequent or persistent occurrence of these events may
indicate a hardware problem or traffic overload on the PKT-CTRL, the
signaling link, or the ASAI adjunct. Resolve the problem by following the
repair procedures for the PKT-CTRL. If these attempts fail, re-engineering
the traffic on the PKT-CTRL, signaling link, or adjunct may be necessary.
g. The ASAI message is not transmitted because the transmit buffer for the
ASAI link is full, causing the link to be flow-controlled. Frequent or
persistent occurrence of these events may indicate a hardware problem
or traffic overload on the PKT-CTRL, the signaling link, or the ASAI
adjunct. Resolve the problem by following the repair procedures issued
by the manufacturer of the adjunct. If these attempts fail, re-engineering of
the traffic on the PKT-CTRL, signaling link, or adjunct may be necessary.
h. This version of ASAI is not supported. Check the software version that is
running on the ASAI adjunct.
i. The adjunct identification is invalid. Check the vendor ID or software
running on the ASAI adjunct.
j. This occurs when the point-to-point signaling link to the endpoint goes
down, except when the link goes down because either a system
technician has busied out the PKT-CTRL or the PKT-BUS, or they have
failed. This error raises an alarm against the endpoint or adjunct. Execute
the test station extension short command and note 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
re-established to the endpoint or adjunct.
k. The switch software logs certain ASAI cause values. The cause value is
determined from the following formulas:
— If the error type is greater than 3712, then the ASAI cause value is
equal to the error type minus 3712. The switch sent this value to the
adjunct.
— If the error type is less than 3712, then the ASAI cause value is
equal to the error type minus 3584. The switch sent this value to the
adjunct.
Table 10-44 contains a description of the various ASAI cause values and
recommended system technician actions associated with the cause value.
The ISDN-BRI Specification (AT&T PUB 801-802-100) contains further
information. In addition, the Aux Data field of the Error Log entry contains
additional diagnostic information.
l. The switch software logs certain ASAI cause values. The cause value is
determined from the following formula:
— If the error type is greater than 3968, then the ASAI cause value is
equal to the error type minus 3968. The switch sent this value to the
endpoint.
