sonusApsChannelStatus

Module: SONUS-SONET-APS-MIB

OID (symbolic): SONUS-SONET-APS-MIB::sonusApsChannelStatus

OID (numeric): 1.3.6.1.4.1.2879.2.5.9.1.3.1.6

Node type: OBJECT-TYPE

Type: Bits

Access: read-only

Description: Indicates the current state of the channel.

Bit 0 - Signal Degrade (SD) Condition. Indicates a 'soft failure' condition resulting from the Line BER exceeding a pre-selected threshold.

Bit 1 - Signal Fail (SF) Condition. Indicates a 'hard failure' condition detected on the incoming OC-N signal.

Bit 2 - Locked Out. This bit, when applied to a working channel, indicates that the channel is prevented from switching to the protection line. When applied to the null channel, this bit indicates that no working channel may switch to the protection line.

The remaining states only apply to working channels which have attempted to initiate an automatic protection switch.

Bit 3 - Switched. Indictes that the working channel is currently switched to the protection line.

Bit 4 - Both Lines Failed. Indictes that both the working line and the protection line are currently in a failure state.

Bit 5 - Protection Line Busy. Indictes that the protection line is busy servicing a different working channel. (This condition can only occur in the 1:n architecture.)

What is sonusApsChannelStatus?

Read-only BITS reporting this channel's current condition across six flags (signal degrade, signal fail, locked out, switched, both lines failed, protection line busy), giving an admin a compact per-channel protection-switching health snapshot.
