ASCEND-MIBTHRESHHDSL2SHDSL-MIB

Description: Manages performance thresholds and alert levels for HDSL2 and SHDSL lines on Ascend 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.

This is a proprietary Ascend Communications MIB defining performance thresholds and alert levels for HDSL2 and G.SHDSL lines on Ascend DSL access equipment. It exposes configurable threshold values for line performance parameters, such as error rates, used to trigger alerts/traps when line quality degrades. It is directly used for monitoring hardware/line status — comparing live DSL line performance counters against configured thresholds to flag failing or marginal copper loops before they cause an outage. It complements the standard HDSL2-SHDSL-LINE-MIB (RFC 3276) framework, which defines the underlying performance counters that these thresholds apply to. It is deployed on Ascend DSL access multiplexers/routers delivering HDSL2/SHDSL business-grade circuits. Engineers can download the ASCEND-MIBTHRESHHDSL2SHDSL-MIB file directly to load it into their MIB browser.

No sample objects were captured for this module, but a threshold MIB of this kind typically exposes a configuration table (an ascendThreshHdsl2Shdsl*Table/Entry pattern) with settable threshold values for errored seconds or loop attenuation, paired with trap notifications when a threshold is crossed. An administrator would set an errored-seconds threshold and receive a trap when a line exceeds it, indicating a degrading SHDSL loop that may need a truck roll.

Sets alarm thresholds for HDSL2/SHDSL line quality metrics including attenuation, SNR, and error rates.
