the trunk, thus
transmitting a yellow
alarm to the network.

of service.
The secondary trunk is
out of service.
Trunk not installed.
Trunk not config/
enabled.
Signal impairment
exceeds threshold.
Consecutive terminal
framing bits have errors
in their framing patterns,
making the signal
unrecognizable.
Results from poor
synchronization of the
T1 clocks. After a slip,
the system attempts
resynchronization.
Two consecutive
nonzero signal elements
have the same polarity.
