Juniper Networks M20 manual Optical Interface Support for Channelized OC12 PICs

Channelized OC12 PIC

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
