Notes:
a. Loss of continuity of Layer 1 to the far-end. It i s assumed that Layer 1
remains active, even when both B-Channels are id le.
This test determines whether Layer 1 is active or not. If Laye r 1 is not
active, the test attempts to ac tivate it. If Layer 1 cannot be ac tivated, the
port is taken out of service, and the test fails.
b. The D-Channel failed at Layer 2. Expiration of this timer ind icates that
attempts to bring the failed link back into servic e have not succeeded and
some recovery actions should be taken on the associated B-Channels.
Upon expiration, associated in-service B-channels are p ut in the
out-of-service/far end state.
