Description: Manages HDSL GT2020 line termination units, providing performance monitoring and alarm objects for DSL loops.
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 HDSLGT2020-MIB?
HDSLGT2020-MIB is a GDC (General DataComm) private MIB for the GT2020 HDSL (High-bit-rate Digital Subscriber Line) line termination unit, providing system version, alarm, and performance monitoring objects for HDSL loops. It exposes system-level version information alongside a dedicated alarms branch covering conditions such as no-response, diagnostic receive error, and power-up alarms on the DSL line. This is fundamentally a fault/status monitoring MIB for telecom line termination hardware: alarm objects like hdslGT2020NoResponseAlm and hdslGT2020PowerUpAlm let an operator detect a failed or power-cycled HDSL unit, and hdslGT2020DiagRxErrAlm flags line-quality diagnostic errors. It appears self-contained to the GT2020 platform's own object model without an explicit dependency on external DSL standard MIBs like HDSL2-SHDSL-LINE-MIB. It is deployed in telecom access networks using GDC GT2020 HDSL line termination equipment to extend copper-loop services, where alarm visibility is essential for line maintenance. Engineers can download the HDSLGT2020-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HDSLGT2020-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.
Supported Devices
- GDC GT2020 HDSL line termination unit
Monitoring Examples
An administrator monitoring hdslGT2020Alarms can check hdslGT2020NoResponseAlm to detect a remote HDSL unit that has stopped responding, indicating a line fault or unit failure. A set hdslGT2020PowerUpAlm flag would reveal the unit recently rebooted (e.g., due to a power interruption), and hdslGT2020DiagRxErrAlm rising would indicate deteriorating line quality requiring a technician dispatch.
What Can Be Monitored
- no-response alarm status
- power-up/reboot alarm
- diagnostic receive error alarm
- system/firmware version
