Juniper Networks M20 manual Optical Interface Support for Channelized OC12 IQ PICs

Channelized OC12 IQ PIC

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

Instrumentation (counters)

■Alarm indication signal (AIS-L, AIS-P)

■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)

■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

■Yellow alarm bit (X-bit) disagreements

■Layer 2 per-queue and per-channel packet and byte counters
