LED Functions

RMT: displays the remote unit's LED status on the local unit
BPV: displays bi-polar violation(s) for the ingress T1/E1 signal
CRC: displays error(s) in data integrity (only for T1 ESF frame and E1 built-in
CRC)
SYNC: displays frame locking for T1 (ESF framing) or E1 (PCM31C framing)
The alarm LEDs - BPV, CRC and SYNC - all have a latching functionality to
indicate the number of occurrences for each error. These LEDs will continuously
flash at regular intervals until reset by the user. The behavior is noted here:
• When an LED blinks once, it indicates a single error has occurred once. When
an LED blinks twice, it indicates the error has occurred twice. When the LED
blinks 3 times, it indicates the error has occurred 3 or more times.
The 600Ω Analog Tx and Rx LEDs are tied to a volume threshold level of -31dBm;
when the volume is greater than -31dBm, the LED(s) will turn on.
