This is done in the NT1+ itself, and is enabled by an AT command. I
don't have the docs handy, but it's somewhere in this dial command:
"AT!Z=9!T0=0!T1=0!T2=1!T4=1Dxxxxxxx".
I set this one up on a RH7.3 system a couple of years ago and it works
perfectly, using pppd just like any other modem. The difference is that
you use e.g. /dev/input/ttyACM0 instead of /dec/ttyS0. You also need
the appropriate usb modules listed in /etc/modules.conf.

You always have both available. The NT1+ automatically switches
between one and two lines as necessary. It runs at 128k until a call
comes in, or you pick up your handset to make a call, then it drops back
to 64k until the call is over.
