Category: Optical and WDM, Vendor: Ascend/Lucent

Description: Manages OC-3 optical interface configuration and SONET section/line parameters 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.

What Is ASCEND-MIBOC3INT-MIB?

ASCEND-MIBOC3INT-MIB is a proprietary Ascend Communications MIB for configuring and monitoring OC-3 optical interfaces and their SONET section/line parameters on Ascend equipment. It exposes both configuration data (framing mode, interface provisioning) and operational/alarm data for the optical and SONET layers. This is fundamentally a hardware-status MIB, used to monitor optical signal presence, SONET section/line alarm indications (such as loss of signal or loss of frame), and bit-error statistics that reveal a degrading fiber link or transceiver. It complements standard SONET/optical MIBs (e.g. the IETF SONET-MIB) by adding Ascend-specific interface detail on the same physical port. It was deployed on Ascend high-speed WAN edge and core equipment carrying OC-3 fiber links for carriers and large enterprises. Network engineers evaluating or troubleshooting this functionality can download the ASCEND-MIBOC3INT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-MIBOC3INT-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

Ascend OC-3 WAN edge router
Ascend SONET-capable access equipment

Monitoring Examples

An operator would poll the OC-3 interface and SONET alarm tables (an ascendOc3IntTable/ascendOc3AlarmEntry style structure) to check for active loss-of-signal or loss-of-frame alarms and rising line bit-error counts, which together would indicate a failing optical transceiver or a fiber cut rather than a configuration issue. No sample objects were supplied for this MIB, so these names are inferred from the stated OC-3/SONET purpose rather than confirmed from source.

What Can Be Monitored

OC-3 signal presence
SONET section/line alarm status
line bit-error rate
framing mode configuration
optical interface operational state
