ATM2 OC12/STM4 IQ PIC

Cables and connectors

LEDs

Alarms, errors, and events

■Duplex SC/PC connector (Rx and Tx)

■Optical interface support—See Table 7 on page 21

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

■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

■Errored seconds (ES-S, ES-L, ES-P), far-end bit errors REI-L, REI-P (CV-LFE, CV-PFE), 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)

■Loss of cell delineation (LOC), loss of frame (LOF), loss of pointer (LOP-P), loss of signal (LOS)

■Payload mismatch (PLM-P), payload unequipped (UNEQ-P)

■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)
