Help pppd

Please can somebody help me in configuring Gnome ppp on Debian 4.0r1 ?

I connec to trough a cellular phone on USB.
It connects and for 2 minutes I can even log to a DX Cluster, then pppd dies with error 15:
"Lack of LCP responses"

I have tryed some changes in the config file in /etc/ppp but no result.

Haw can I convince pppd to stay alive ?

Thanks for the help
