Strange PPP Disconnect errors?

I had this problem with a Sprint EVDO card. If I remember correctly,
Linux's PPP implementation will attempt to do LCP echo tests by default,
which the card doesn't support. After a certain number of these echos
time out, the session will disconnect.

Since your session lasted exactly 40 seconds, I'd suspect that it's
trying 4 echos at 10 second intervals.

Try adding 'lcp-echo-interval 0' to your ppp configuration, this will
disable the test.
