If its an external ISDN modem, connected to your Linuxbox, you just need the pppd and chat programs installed. Then you can make a "connect-script", as it was a "normal" analog modem, like:


pppd /dev/ttyS? 115200 modem crtscts connect \
    'chat -v "" ATZ??DT<isp-phone#> CONNECT ""' \
    <additional pppd options, look at the manpage for pppd>

Your ISP may use PAP as authentication; place your account-name, and password, in the pap-secrets file (located in /etc/ppp/pap-secrets on my RedHat 6 box)..

hope that helps..;-)
