ds1LineStatus
Module: ACMIB
OID (symbolic): ACMIB::ds1LineStatus
OID (numeric): 1.3.6.1.4.1.1751.2.18.2.5.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This variable indicates the Line Status of the interface. It contains loopback, failure, re- ceived 'alarm' and transmitted 'alarm' infor- mation.
The dsx1LineStatus is a bit map represented as a sum, therefore, it can represent multiple failures (alarms) and a LoopbackState simultaneously.
ds1NoAlarm should be set if and only if no other flag is set.
If the ds1LoopbackState bit is set, the loopbak in effect can be determined from the ds1LoopbackConfig object.
The various bit positions are: 1: dsx1NoAlarm: No Alarm Present 2: dsx1RcvFarEndLOF: Far end LOF (a.k.a., Yellow Alarm) 4: dsx1XmtFarEndLOF: Near end sending LOF Indication 8: dsx1RcvAIS: Far end sending AIS 16: dsx1XmtAIS: Near end sending AIS 32: dsx1LossOfFrame: Near end LOF (a.k.a., Red Alarm) 64: dsx1LossOfSignal: Near end Loss Of Signal 128: dsx1LoopbackState: Near end is looped 256: dsx1T16AIS: E1 TS16 AIS 512: dsx1RcvFarEndLOMF: Far End Sending TS16 LOMF 1024: dsx1XmtFarEndLOMF: Near End Sending TS16 LOMF 2048: dsx1RcvTestCode: Near End detects a test code 4096: dsx1OtherFailure: any line status not defined here 8192: dsx1RmtLoopback: Far end loopback
What is ds1LineStatus?
This read-only OID reports the current state of the DS1 line as a numeric bitmap containing loopback, failure, and alarm flags, giving a complete picture of the line's health. Network engineers monitor this continuously to detect loss of frame alignment, far-end receive failures, and other provisioning problems. For example, a value of 1 indicates no problems, while a value of 4 means the line detected a yellow alarm from the remote end (signaling a remote fault).
