Front Panel Description
Item Function
Status:
The green LED li ghts when the unit is power ed and operating normally. The red LE D lights if an alarm
exceeding thresholds is de tected or for other unit failure.
ACO:
This yellow LED li ghts if the A C O (al arm cut off) switch is place d in the left ON posi ti on. It indic at es tha t
the alarm relay cont acts are disabled.
ACO SW:
This ACO (alarm cut off) switc h controls the alarm relay circuitry. If the switch is plac ed in the left
ON position, this circuitry is deactivated.
BV/CR/ FE:
This LED lights one second for ea ch occurrence of bipolar violations, cyclic redundancy c heck
errors, or frame bit errors.
LOS/OOF:
This LED blinks with a loss of signal (LOS) from the network. It lights constantly when an out of
frame (OOF) condition is detected.
AIS:
This alarm indication signal LED lights if an unframed all ones condition is detected from the network.
REM ALM:
LOC ALM:
LLB:
This LED lights constantly when a remote (yellow) alarm signal is received.
This LED lights w h en a local alarm exc eeding alarm th res holds exists.
This LED lights contin uously when the network interface is in a lin e l oopback. It flashes when the T1
DTE interface is in a line loopback .
PLB:
This LED lights continuously when the network interface is in a payload loopback.
FLB:
This LED is active for port loops. It lig hts continuously when th e unit is in a fractional (high-speed port) loop.
TST :
This LED lights continuously during a far or local test. It flas hes while loop codes are transmitted at the

This switch is used for local testing with the test pattern selected by the rotary switch Pattern Select.
This pattern select switch determines the BERT pattern sent by the unit when the test sw itch is in the
