Notes:
a. Loss of continuity of Layer 1 to the far-end. It is assumed that Layer 1
remains active, even when both B-Channels are idle.
The Layer 1 State Test is a simple query to see if Layer 1 is active or not,
runs on each B-Channel only if the port is idle.
b. The D-Channel failed at Layer 2. Expiration of this timer indicates that
attempts to bring the failed link back into service have not succeeded and
some recovery actions should be taken on the associated B-Channels.
Upon expiration, associated in-service B-channels are put in the out of
service/far end state.
c. Error Type (513): On-board hardware failure. The FIFO RAM buffers have
overflowed, indicating a hardware problem.
d. Error Type (769): The port is generating too many uplinks. The link is being
suspended.
1. Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the
appropriate test description and follow the recommended procedures.
2. The far end switch changed the ISDN service state. This may be a temporary condition.
