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.
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

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.
