f. This error occurs when the signaling link assoc iated with a BRI endpoint
has too much link establishment related traffic. This could occ ur if the
signaling link is bou ncing between assig ned and established states.
Software will suspend activity to this end point for 75 minutes when the
endpoint is alarmed d ue to this problem (note that servic e suspension
does not occur if the end point is an ASAI or Lucent adjunc t). If this
problem persists, replac e the endpoint. If replaci ng the endpoint does not
fix the problem, follow normal escalation procedures.
g. This error occurs when the ASAI-ADJ or ATT-ADJ or LGATE-AJ or ATTE-AJ
message is not transmitted bec ause the PKT-CTRL (P acket Control Circuit
Pack) transmit buffers are exhausted. Frequent or p ersistent occurrence
of these events may indicate a hard ware problem or traffic overload on the
PKT-CTRL, the signaling link, or the ASAI or Lucent adjunct. Attemp t to
resolve the problem by following the repair procedures for the PKT-CTRL.
If these attempts fail, the problem should be escalated b ecause
re-engineering of the traffic on the PKT-CTRL, signaling link, or adjunc t
may be necessary.
h. This error occurs when the ASAI message is not transmitted because the
transmit buffer for the ASAI link is full, causing the l ink to be flow
controlled. Frequent or persistent oc currence of these events may indic ate
a hardware problem or traffic overlo ad on the PKT-CTRL, the signaling
link, or the ASAI or Lucent adjunct. Attemp t to resolve the problem by
following the repair proce dures issued by the manufacturer of the ad junct.
If these attempts fail, the problem should be escalated b ecause
re-engineering of the traffic on the PKT-CTRL, signaling link, or adjunc t
may be necessary.
i. This error indicates a problem with Layer 2 over the D-channel between
the switch and the endp oint. When this error occurs, an alarm is raised
against the station or adjunc t. Execute the test station extension short
command and p ay particular attention to the results of the BRI XID Test
(#628). If this test fails, follow the repair proc edure for Test #628.
j. This error indicates a problem with the B-c hannel connection between the
switch and the endpoint. When this error occurs, a warning alarm is raised
against the endpoint. Execut e the test station
<extension>
long
command and p ay particular attention to the results of the BRI Remote
Loop Back Test (#627). If this test fails, follow the repair p rocedure for Test
#627.
k. This error occurs whenever the point-to-p oint signaling link to the endp oint
goes down (excep t when it goes down becau se either the PKT-CTRL or
the PKT-BUS has failed or has been busied out b y system technician).
When this error occurs, an alarm is raised ag ainst the endpoint or adjunc t.
Execute the test station
<extension>
short command and p ay particular
attention to the results of the Signaling Link Status Test (#626). If this test
fails, follow the repair proced ure for Test #626. The alarm is retired when
the signaling link is reestabli shed to the endpoint or ad junct.
l. Certain ASAI protocol-specific cause codes are logged by switch
software. The cause code can b e determined from the following formula:
