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

What Is RAD-DS1-MIB?

RAD-DS1-MIB is a RAD Data Communications proprietary MIB extending the standard DS1/T1 MIB with additional current- and interval-statistics objects (built on RAD-GEN-MIB/RAD-MIB). Its current-statistics table reports live DS1 alarm conditions — loss of signal (LOS), loss of frame (LOF), loss of carrier (LOC), AIS, remote alarm indication (RAI), CRC multiframe loss, far-end block errors (FEBE), bipolar violations (BPV), and CRC errors — while a parallel interval table records the same set of counters per 15-minute interval. As a performance/hardware-status MIB it lets an administrator pinpoint exactly which DS1 alarm condition (LOS vs. AIS vs. bipolar violations) is driving circuit errors and how it trends over recent intervals. It is deployed on RAD Data Communications DS1/T1 access equipment. Engineers can download the RAD-DS1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RAD-DS1-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

RAD Data Communications DS1/T1 access equipment

Monitoring Examples

An administrator checks dsx1CurrentBPV and dsx1IntervalBPV across recent 15-minute intervals to determine whether bipolar violations on a DS1 circuit are a one-off event or a persistent line-quality problem.

How to Use in IPNetwork Monitor

Example using dsx1DataStreamStatInFrames OID:

Select an RAD Data Communications DS1/T1 access equipment (alarm/interval statistics) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type dsx1DataStreamStatInFrames into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The counter associated with the number of received frames, encountered by the DS1 Data Stream. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
