The AMU-912 provides a method for Service Loss Alarms to be reported to the Central Office switch or SLC-96
COT via the TR-08 Derived Data Link. The Service Loss Alarms occur when six or more POTS lines lose
service. These alarms can be triggered by removal of line units, Loss of Signal (LOS) or Loss of Frame (LOF) of
the High-bit-rate Digital Subscriber Line (HDSL)/Symmetric High-bit-rate Digital Subscriber Line (SHDSL), etc.
When a Service Loss Alarm is detected, the AMU-912 will report a TR-08 Shelf A, B, C, or D Major or Minor alarm
to the TR-08 shelf or switch. The type of alarm is determined by the CO Line Unit type that has the "Active" Service
Loss Alarm (e.g., Shelf A, B, C, or D alarms are only reported against the FLL-814.) The severity and CO Line Unit
location of the Service Loss Alarm will determine what TR-08 alarm is reported. Refer to
