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.
