LEDs
|
One tricolor per port:

- Green—Online with no alarms or failures
- Amber—Online with alarms for remote failures
- Red—Active with a local alarm; router has detected
a failure
|
Alarms, errors, and events
|
- Alarm indication signal (AIS)
- Bit error rate test (BERT) functionality on PIC (you can
configure one DS3 channel in BERT mode and configure the remaining
channels to transmit and receive normal traffic)
- Equipment failure (does not affect service)
- Far-end block error (FEBE)
- Frame error
- Idle code, Idle received
- Local and remote loopback
- Loss of signal (LOS)
- Out of frame (OOF)
- Parity bit (P-bit) disagreements
- Path parity error
- Yellow alarm bit (X-bit) disagreements
