Module: CM-PERFORMANCE-MIB

OID (symbolic): CM-PERFORMANCE-MIB::e1t1StatsPathAISs

OID (numeric): 1.3.6.1.4.1.2544.1.12.5.1.55.1.22

Node type: OBJECT-TYPE

Type: PerfCounter64

Description: The counter associated with the number of Path AISs encountered by a E1/T1 interface in the current bin.

What is e1t1StatsPathAISs?

This PerfCounter64 counts Path AISs (Alarm Indication Signal seconds) encountered by an E1/T1 interface in the current bin, i.e. seconds during which an upstream failure was signaled downstream as an AIS pattern. An admin treats live AIS seconds as evidence the fault lies somewhere upstream of this interface rather than at the interface itself, since AIS is a relayed alarm, not a locally-detected error. If e1t1StatsPathAISs starts accumulating on a T1 drop, the admin's next step is to check the upstream multiplexer or backhaul link feeding that drop rather than the local T1 port.
