The Far-End AIS condition occurs when an AIS has occurred at the far-end node. FE-AIS usually occurs
in conjunction with a downstream LOS alarm (see the
Generally, an AIS is a special SONET signal that tells the receiving node that the sending node has no
valid signal available to send. AIS is not considered an error. The AIS condition is raised by the receiving
node on each input when it detects the AIS instead of a real signal. In most cases when this condition is
