Leased Line Operation (2-wire) with the IG6000 requires a specific RJ-11 cable to be used. The RJ-11 cable needs to have Pins 1 and 6 in use, as the IG6000 uses both these pins for Transmit and Receive.
One way of configuring Leased Line Mode is an Automatic Leased Line connection. It is best to reset the profile to defaults and then to write the changes (AT&F&W) before continuing. AT&L2 will need to be issued to the modem which will be acting as the Originating modem, and AT&L3 will need to be issued to the modem which will be acting as the Answering modem.
