What Is PANDATEL-FHFLF-MODEM-MIB?

PANDATEL-FHFLF-MODEM-MIB is a vendor MIB from Pandatel, a German telecom access equipment maker, for its FHFLF series fiber-to-copper modem/converter units used to extend leased-line style circuits over mixed fiber/copper paths. It exposes an inventory and configuration table of installed modems identified by rack and position, along with per-modem operating parameters such as interface emulation mode, clocking system/source, data rate, and timeslot assignment. Its monitoring value is chiefly in tracking the configuration/status of each modem unit -- confirming a modem in a given rack/position is present and correctly named, and that its clock source, data rate, and timeslot settings match the intended circuit provisioning, functioning as a hardware/line-configuration health check. No dependency on standard IETF MIBs is apparent; it appears to be a self-contained enterprise MIB for this product line. It would be deployed in telco or enterprise environments running Pandatel FHFLF fiber/copper conversion equipment to carry leased circuits across mixed-media links, and administrators can download the PANDATEL-FHFLF-MODEM-MIB file to load it directly into their MIB browser for monitoring these units.

IPNetwork Monitor allows you to monitor SNMP objects defined in PANDATEL-FHFLF-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 fhflfModemTable/fhflfTableEntry, indexed by mdmRack and mdmPosition, to enumerate every installed modem and read mdmModemName to confirm physical inventory after a rack change. Checking mdmClockSystem and mdmClockSource verifies the modem is deriving timing from the expected source, since a clocking mismatch across a link causes bit errors. mdmDataRate and mdmStartTimeslot confirm the circuit's bandwidth and TDM timeslot allocation match what was provisioned, and mdmInterfaceEmulationMode confirms which line emulation the modem is running.

What Can Be Monitored

modem inventory by rack/position
clock system and source
data rate

OID symbolic	OID numeric	Type	Access	Description
fhflf	1.3.6.1.4.1.760.1.1.2.1.10.102
fhflfModemTable	1.3.6.1.4.1.760.1.1.2.1.10.102.1		not-accessible	This table contains information about all FH/FL-F modems in all racks.
fhflfTableEntry	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1		not-accessible	The index of the table.
INT mdmRack	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.1	INTEGER	read-only	The index of the rack where the modem is installed.
INT mdmModem	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.2	INTEGER	read-only	This entry displays the slot number where the corresponding modem is installed in the rack.
INT mdmPosition	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.3	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	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.5	DisplayString	read-only	The verbal name of this modem.
INT mdmInterfaceEmulationMode	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.6	INTEGER	read-only	Interface mode of the unit: 'dte', 'dce', 'te' or 'nt'.
INT mdmModemProperty	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.7	INTEGER	read-only	This entry displays the speed class of the FH/FL-F: 'e1' or 't1'.
INT mdmClockSystem	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.23	INTEGER	read-write	The clock system of the link: 'dual' or 'single'.
INT mdmClockSource	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.24	INTEGER	read-write	The clock source of the link: 'internal', 'external', or 'remote'.
INT mdmDataRate	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.25	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. A data rate of 1.984 Mbps (E1) automatically sets mdmStartTimeslot to 'timeslot-1', enables time slot 16. A data rate of 1.544 Mbps (T1) automatically sets mdmStartTimeslot to 'unframed'.
INT mdmStartTimeslot	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.26	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.
INT mdmTimeslotSize	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.27	INTEGER	read-write	This entry determines the size of the time slots: 'nx64k' or 'nx56k'. 'nx56k' is valid for T1 units only. The remote unit's configuration changes simultaneously.

INT mdmLocalCarrierDetect	1.3.6.1.4.1.760.1.1.2.1.10.102.1.1.60	INTEGER	read-write	The data carrier detect mode at the interface: if set to 'fo-link-and-remote-handshake' the DCD signal (resp. I for X.21, etc.) follows link status and remote RTS (resp. C for X.21, etc.), if set to 'fo-link' the DCD signal follows link status only.
