What Is PANDATEL-GMD-MODEM-MIB?

PANDATEL-GMD-MODEM-MIB is a vendor MIB for Pandatel's GMD series HDSL/leased-line modem units used in WAN access equipment. It exposes configuration and status data organized by rack, modem, and slot position, including modem naming, data-equipment emulation, HDSL unit assignment, and clock source/system settings. Its main use is monitoring hardware status of the modem chassis: administrators track modem presence/position in the rack, the HDSL line unit in use, and the configured data rate to confirm the physical line module is operating as provisioned. As a self-contained physical-layer modem MIB, it has minimal dependency on other standard MIBs, functioning largely independently of IETF interface or entity MIBs. It is deployed in telecom/WAN environments where Pandatel GMD modem racks provide HDSL leased-line connectivity between sites. Network engineers evaluating or troubleshooting this functionality can download the PANDATEL-GMD-MODEM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PANDATEL-GMD-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 walk gmdModemTable to enumerate each mdmRack/mdmModem/mdmPosition combination and confirm mdmModemName and mdmHDSLUnit assignments match the physical installation. Checking mdmClockSystem and mdmClockSource verifies whether a modem is running on internal or line-derived timing, which is critical for HDSL synchronization; a mismatch here often explains line errors. mdmDataRate would be polled to confirm the negotiated line speed matches the provisioned service rate.

What Can Be Monitored

modem rack/slot/position inventory
modem name/identity
HDSL line unit assignment
clock system and clock source
negotiated data rate
data equipment emulation mode

gmdModemTable	1.3.6.1.4.1.760.1.1.2.1.10.203.1		not-accessible	This table contains information about all GM-D modems in all racks.
gmdTableEntry	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1		not-accessible	The index of the table.
INT mdmRack	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1.1	INTEGER	read-only	The index of the rack where the modem is installed.
INT mdmModem	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1.2	INTEGER	read-only	This entry displays the slot number where the corresponding modem is installed in the rack.
INT mdmPosition	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1.3	INTEGER	read-only	This entry displays the location of the corresponding modem: 'local' or 'remote'. The modem which is plugged into a managed rack is 'local', the counterpart is 'remote'.
STR mdmModemName	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1.5	DisplayString	read-only	The verbal name of this modem.
INT mdmDataEquipmentEmulation	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1.6	INTEGER	read-only	Interface mode of the unit: 'dte' or 'dce'.
INT mdmModemProperty	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1.7	INTEGER	read-only	This entry displays the speed class of the GM-D: 'e1'.
INT mdmHDSLUnit	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1.10	INTEGER	read-only	HDSL unit type: Line Termination Unit ('LTU') or Network Termination Unit ('NTU')
INT mdmClockSystem	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1.23	INTEGER	read-write	The clock system of the link: 'dual' or 'single'.

INT mdmDataRate	1.3.6.1.4.1.760.1.1.2.1.10.203.1.1.25	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 mdmStartChannel to 'unframed' and enables time slot 16. A data rate of 1.984 Mbps (E1) automatically sets mdmStartChannel to 'channel-1' and enables time slot 16.
