It is not a problem. It is caused by the ppd on your end checking to make
sure the other end is still alive. I used to do similar checking when I
was using Linux boxes as terminal servers. It was right handy because I
could use the lcp-echo-failure command to determine whether the PPPD was
talking to another computer or a modem with a stuck DCD bit. (I had to
stop because of occasional problems with magic number negotiation. I
don't recall the circumstances better than this.)
I don't know if this works (and, no offense, but I'm not going to dig
through the source for pppd to find out---do it yourself if you're of a
mind to) but I would suspect that setting the "lcp-echo-interval" value to
0 might turn it off. According to the man page (you did read the man page
for pppd, didn't you?) lcp-echo-interval sets the interval between echo
requests if no other traffic is on the line. It apparently defaults to 60
on your machine.
