Modem types of teleservice devices

1. Hardware modem type

The hardware modem type represents the physically installed modem.
You'll find this number in the System Info page of the device at:

Let's say, the device has the Hardware Modem Type = 7 for ISDN modem.

Now refer to the actual Error:
e.g. "Reference source not found for the list of hardware modem type".

2. Software modem type

The software modem type represents how device manages the modem.
You'll find the Software modem type in the parameter "ModExpType" and ("ModFrcType") of
the file "comcfg.txt".

In this example, the Software Modem Type = 10 for ISDN commands.
Effectively, several hardware can be used exactly with the same commands, then, for the device,
the software used is the same for several hardware.

Now refer to the actual error:
e.g. "Reference source not found for the list of software modem type".

By default, you can leave "ModFrcType" set to value -1 (no forcing), otherwise,
set it to the same value as "ModExpType".

PLEASE NOTE: Forcing of the modem, disables the detection of the modem.


  • The value "-1" for the "ModExpType" may be used to let device auto detect the modem.
    Set the "ModExpType:-1" and "ModFrcType:-1" in the comcfg.txt file.
  • To disable the modem of the device, set the ModExpType:0 and ModFrcType:0 in the comcfg.txt file.
