Set the Operating Modes Answer or Originate
By factory default, the i-modul Modem 336 LL 3.0 is usually delivered for operation in
originate or answer mode. To operate a leased line, you will always require two modems,
one in originate mode and one in answer mode. Despite the preset factory default, the i-
modul Modem 336 LL 3.0 can be reconfigured for the other mode. This may be reason-
able if a leased line is being repaired, and a device with the wrong mode is available to
replace the affected device. After configuring the available device for operation in the
mode of the failed device, you can replace the devices.
For changing only the 2 or 4 wire operation, it’s sufficient to set the
AT&L
parameter.
