With your TA, you're going to end up talking through a 115200bps
serial connection to a 128bps bundled ISDN connection - not exactly
ideal.... You should really invest in an ISDN card (and use the
examples in /usr/share/examples/ppp/*isdn*).
It doesn't really matter which version of ppp you use with your TA
- all ppp gets to see is a non-multi-link connection. The TA mangles
the incoming and outgoing LCP requests so that it negotiates
multi-link with the peer while the local machine isn't looking. Of
course you've got to figure out the magic AT commands you need to
make it do this.
