What Is ADTRAN-ATLAS550-QUAD-BRI-U-MIB?
ADTRAN-ATLAS550-QUAD-BRI-U-MIB is an ADTRAN vendor MIB for the ATLAS 550 multiservice access platform's quad BRI-U interface module, which provides four ports of U-interface Basic Rate ISDN connectivity. It exposes per-port line-quality counters, specifically near-end block error (NEBE) and far-end block error (FEBE) counts, along with a control to reset those counters. Its monitoring value is line/hardware health at the physical layer -- rising block-error counts on a given port point to a degraded BRI-U loop, bad wiring, or connector fault before the line fails outright. It is registered under ADTRAN's adtran/adMgmt enterprise branch and does not depend on external standard ISDN MIBs based on the available text. It is deployed on ATLAS 550 chassis fitted with the quad BRI-U module at sites requiring dense BRI ISDN port density with per-port error monitoring. Engineers can download the ADTRAN-ATLAS550-QUAD-BRI-U-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ADTRAN-ATLAS550-QUAD-BRI-U-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
- ADTRAN ATLAS 550 multiservice access device (quad BRI-U interface module)
Monitoring Examples
An administrator would poll adATLAS550QuadBRIUIfNEBE and adATLAS550QuadBRIUIfFEBE per adATLAS550QuadBRIUIfIndex to track near-end and far-end block error counts on each BRI-U port. Rising values on one port relative to its peers would point to a degraded local loop or a bad connector on that specific line. After a technician replaces a cable or corrects a wiring fault, adATLAS550QuadBRIUIfResetBECounts would be used to clear the counters and confirm the fix by watching for a return to zero errors.
What Can Be Monitored
- per-port near-end block error count
- per-port far-end block error count
- block error counter reset control
