ADTRAN-ATLAS-HSSI-V35-MIB

Description: Manages HSSI and V.35 serial WAN interfaces on ADTRAN ATLAS multiservice access devices.

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 ADTRAN-specific MIB manages the HSSI (High-Speed Serial Interface) and V.35 serial WAN interface modules on the ADTRAN ATLAS multiservice access platform. Given its placement in the ADTRAN ATLASmg management OID subtree, it exposes configuration and status objects for these legacy serial WAN interface cards, such as interface clocking, line state, and cable-type/DTE-DCE role settings. Its role is primarily hardware interface status monitoring — confirming that an HSSI or V.35 WAN card is present, correctly configured, and reporting a healthy link/carrier-detect state rather than software-level metrics. It is typically used together with other ADTRAN ATLAS management MIBs sharing the same adATLASmg subtree, and often alongside the IETF IF-MIB for generic interface counters. It's deployed on ADTRAN ATLAS multiservice access devices connecting to legacy serial WAN circuits such as frame relay or leased lines. Engineers can download the ADTRAN-ATLAS-HSSI-V35-MIB file directly to load it into their MIB browser.

A technician would check the HSSI/V.35 interface module's operational/link status object to confirm a leased-line or frame-relay serial circuit is up before troubleshooting an outage, and verify the configured cable/interface-type setting matches the physical DTE or DCE cable in use. Because this MIB's own detailed object list wasn't available beyond the ATLASmg OID nodes, in practice it is polled alongside ifOperStatus/ifAdminStatus from the standard IF-MIB for the corresponding ifIndex to fully confirm interface health. A mismatch between configured clocking/cable type and actual physical wiring is a common root cause of a serial WAN interface reported down.
