Description: Configures alarm severity assignments for fault conditions on PairGain Technologies DSLAM chassis equipment.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is PAIRGAIN-DSLAM-ALARM-SEVERITY-MIB?

PAIRGAIN-DSLAM-ALARM-SEVERITY-MIB is a vendor-specific SNMP module from PairGain Technologies for configuring and reporting alarm severities across a central DSLAM (Digital Subscriber Line Access Multiplexer) chassis, covering everything from chassis-level faults down to individual HDSL/ADSL line card and port alarms. It exposes chassis alarm objects for power supply, fan, temperature, and configuration-change events, plus alarm severity/threshold configuration profile tables for HDSL spans and ADSL ATUC ports. This MIB is explicitly built around fault and hardware health monitoring — it lets an operator monitor power supply status, fan status, and chassis temperature alarms, and configure how severely each condition should be flagged, which is central to proactive DSLAM maintenance. The module explicitly notes dependency on external standards for line-level alarm semantics, referencing a proprietary HDSL alarm spec and the ADSL Forum's AdslLineMib (TR-006) for ADSL alarm architecture. It is deployed in telecom central office DSLAM chassis where broadband access line cards need consistent, prioritized alarm reporting to the NOC. Engineers can download the PAIRGAIN-DSLAM-ALARM-SEVERITY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PAIRGAIN-DSLAM-ALARM-SEVERITY-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An operator polls pgDSLAMChassisPsAlarmSeverity and pgDSLAMChassisFanAlarmSeverity to confirm how power supply or fan failures will be escalated, and checks pgDSLAMChassisTempAlarmSeverity to see the configured severity for over-temperature events. Using pgDSLAMHDSLSpanAlarmThresholdConfProfileTable/Entry, an administrator sets threshold profiles that determine when an HDSL span alarm fires, and cross-references pgDSLAMADSLAtucAlarmTable to see current ADSL port-level alarm states. A chassis reporting an elevated pgDSLAMChassisTempAlarmSeverity condition alongside multiple ADSL ATUC alarms would point to a cooling failure affecting multiple line cards simultaneously.

What Can Be Monitored

chassis power supply alarm status
chassis fan alarm status
chassis temperature alarm status
HDSL span alarm thresholds
ADSL ATUC port alarms
chassis configuration-change alarms

pgdsalsvMIB	1.3.6.1.4.1.927.1.9.3.1			The MIB module defining objects for the alarm severity configuration and status management of a central DSLAM (Digital Subscriber Line Access Multiplexer), including from chassis power supply, fan status, to each channel/port related alarms in each HDSL/ADSL card inside the chassis. For HDSL alarm management: Please refer to Spec#157-1759-01 by Ken Huang for detail architecture model. For ADSL alarm management: Please refer to AdslLineMib(TR006) from adslForum for details architecture model. Naming Conventions: Atuc -- (ATU-C) ADSL modem at near (Central) end of line Atur -- (ATU-R) ADSL modem at Remote end of line ES -- Errored Second.
