The connection sequence has probably been modified on your machine or your
isp. The file is /etc/ppp.chatscript (see "man chat"). The loopback
means that what you type is echoed back which means the isp didn't start
up the ppp connection. (If you can't figure it out from log files and the
chatscript, dial in with minicom and remember what the isp sends and what
you respond with to get the ppp garbage to start arriving.)
My termonology may be wrong, but you get the idea,
