LEDs One tricolor per port:
- Off—Not enabled
- 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-L, AIS-P)
- BERT functionality (you can configure one DS3 channel in BERT mode and configure the remaining channels to transmit and receive normal traffic)
- Bit error rate signal degrade (BERR-SD), Bit error rate signal fail (BERR-SF)
- Bit interleaved parity errors B1, B2, B3 (CV-S, CV-L, CV-P)
- Equipment failure (Does not affect service)
- Errored seconds (ES-S, ES-L, ES-P), far-end bit errors REI-L, REI-P (CV-LFE, CV-PFE), far-end block error (FEBE), far-end errored seconds (ES-LFE, ES-PFE), far-end severely errored seconds (SES-LFE, SES-PFE), far-end unavailable seconds (UAS-LFE, UAS-PFE)
- Frame error
- Idle code, Idle received
- Loss of frame (LOF), Loss of pointer (LOP-P), Loss of signal (LOS)
- Out of frame (OOF)
- Payload Mismatch (PLM-P), Payload Unequipped (UNEQ-P)
- Parity bit (P-bit) disagreements
- Path parity error
- Remote defect indication (RDI-L, RDI-P)
- Severely errored framing (SEF), severely errored framing seconds (SEFS-S), severely errored seconds (SES-S, SES-L, SES-P), unavailable seconds (UAS-L, UAS-P)
- Yellow alarm bit (X-bit) disagreements
