2.7.413 TIM
The Section TIM alarm occurs when the expected J0 section trace string does not match the received
section trace string. This occurs because the data being received is not correct, and the receiving port
could not be connected to the correct transmitter port.
If the alarm occurs on a port that has been operating with no alarms, the circuit path has changed due to
a fibering misconnection, a TL1 routing change, or to someone entering an incorrect value in the Current
Transmit String field.
TIM occurs on a port that has previously been operating without alarms if someone switches optical
fibers that connect the ports. TIM is usually accompanied by other alarms, such as the
alarm on page 2-164
reattach or replace the original cables/fibers to clear the alarms. If a Transmit or Expected String was
changed, restore the original string.
