junidApsStatusPSBFs

Module: APS-MIB-JUNI

OID (symbolic): APS-MIB-JUNI::junidApsStatusPSBFs

OID (numeric): 1.3.6.1.4.1.4874.3.2.2.1.1.2.1.6

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A count of Protection Switch Byte Failure conditions. This condition occurs when either an inconsistent APS byte or an invalid code is detected. An inconsistent APS byte occurs when no three consecutive K1 bytes of the last 12 successive frames are identical, starting with the last frame containing a previously consistent byte. An invalid code occurs when the incoming K1 byte contains an unused code or a code irrelevant for the specific switching operation (e.g., Reverse Request while no switching request is outstanding) in three consecutive frames. An invalid code also occurs when the incoming K1 byte contains an invalid channel number in three consecutive frames.

What is junidApsStatusPSBFs?

This read-only Counter32 counts Protection Switch Byte Failure events. Network engineers monitor this for corrupted K1 bytes or invalid codes. Rising counts indicate signal quality problems.
