What Is PANDATEL-GMF-MODEM-MIB?

PANDATEL-GMF-MODEM-MIB is a vendor MIB for Pandatel's GMF series modems, a technology area covering leased-line/telecom modem multiplexer equipment used for line emulation and clocking in carrier or industrial telecom networks. It exposes configuration and status data for individual modem cards, including their rack/position location, interface emulation mode, line emulation mode, clock system/source, and data rate settings. Administrators use it to monitor hardware status of each modem module — confirming a given modem card is present, correctly configured, and operating at the expected data rate and clock source, which helps detect a misconfigured or failed modem card in the rack. The module appears self-contained around its own gmf-modem object tree rather than depending on external standard MIBs. It is typically deployed in telecom or industrial network operations monitoring racks of GMF modem cards providing leased-line connectivity. Engineers can download the PANDATEL-GMF-MODEM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PANDATEL-GMF-MODEM-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.

Monitoring Examples

An operator would poll gmfModemTable entries via gmfTableEntry, using mdmRack, mdmModem, and mdmPosition to identify a specific modem card, then check mdmDataRate, mdmClockSource, and mdmLineEmulationMode to confirm the modem is running at its expected rate and clocking configuration. A modem reporting an unexpected mdmClockSource or a data rate mismatch from mdmDataRate would indicate a line configuration fault or a modem that has failed over to a fallback clock. These objects are drawn directly from the sample objects provided for this MIB.

INT mdmDataRate	1.3.6.1.4.1.760.1.1.2.1.10.202.1.1.25	INTEGER	read-write	The data rate at the interface in bits per seconds. The data rate at the remote counterpart changes simultaneously. A data rate of 2.048 Mbps (E1) automatically disables CRC4, sets mdmStartTimeslot to 'unframed', enables time slot 16, and disables remote access. A data rate of 1.984 Mbps (E1) automatically sets mdmStartTimeslot to 'timeslot-1', enables time slot 16 and sets mdmRemoteAccessMode to 'via timeslot 0 sa4-bit'. A data rate of 1.544 Mbps (T1) automatically sets mdmStartTimeslot to 'unframed' and disables remote access.
INT mdmStartTimeslot	1.3.6.1.4.1.760.1.1.2.1.10.202.1.1.26	INTEGER	read-write	This entry determines the start time slot for framing. Start time slot and data rate must match. A start time slot which is too high will be ignored. The remote unit's configuration changes simultaneously.

The value 'via-next-free-timeslot' means that one time slot higher than the last data time slot is used for remote access. The value 'via-timeslot-0-Sa4-bit' means that the sa4-bit in time slot 0 is used for remote access (for E1 units only). The value 'via-unframed-line' is valied for data rates of 2048 Kbps (E1) or 1544 Kbps (T1) only. With a data rate of 1536 Kbps (T1). remote management is not available. The remote unit's configuration changes simultaneously.
