Run the short test sequence first. If every test passes, run the long test sequence. Refer to each appropriate

test's description, and follow its recommended procedures.

The far-end switch changed the ISDN service state. This may be a temporary condition.

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.

This test determines whether Layer 1 is active or not. If Layer 1 is not

active, the test attempts to activate it. If Layer 1 cannot be activated, the

port is taken out of service, and the test fails.

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 (514) — Transmit FIFO Overflow - This error indicates that the

circuit pack is having problems transmitting data to the TDM D channel.

This error only occurs only a system that switches the packet

implementation of the D channel over the TDM bus. This error indicates an

on-board problem related to the packet implementation of the D channel

(R6.2 and higher).
