HDSL701T2-MIB

Description: Manages HDSL 701T2 modem units, providing loop performance, alarm, and configuration objects for DSL access.

Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

HDSL701T2-MIB is a vendor-specific MIB (GDC/701T2 family) for managing HDSL (High-bit-rate Digital Subscriber Line) modem units, exposing system version information and a set of loop and equipment alarm conditions for DSL access circuits. It provides configuration and status objects covering the modem's software version and a range of alarm objects, including no-response and power-up alarms plus receive-error diagnostics on the DSL loop. This MIB is explicitly used to monitor hardware status, particularly whether the HDSL unit has recently powered up (indicating a possible outage), whether it is failing to respond to management polls, and whether the receive path is reporting diagnostic errors that would signal line degradation. As a legacy device-specific MIB it does not depend on IETF DS1/DSL standard MIBs, instead defining its own private alarm tree. It is typically deployed on HDSL line units terminating leased-line or T1/E1-over-copper circuits in telecom access networks. Engineers can download the HDSL701T2-MIB file directly to load it into their MIB browser.

An administrator would poll hdsl701T2NoResponseAlm to detect when the modem stops responding to SNMP or line-status queries, which combined with hdsl701T2PowerUpAlm helps distinguish a fresh reboot from a sustained management-plane failure. The hdsl701T2DiagRxErrAlm object flags receive-side diagnostic errors on the HDSL loop, which would indicate line noise or a degraded copper pair. Checking hdsl701T2Version and gdc701T2SystemMIBversion confirms the firmware/software version running on the unit during a fleet audit. A recurring DiagRxErrAlm without a corresponding power-up event would point to a persistent line-quality problem rather than a transient outage.
