Hi,

An pending telnet connection or a keepalive of sshd is not the case:
Here the output of tcpdump:
	tcpdump -i isppp0 
	tcpdump: listening on isppp0
	10:50:07.859714 [|ip]
	10:50:07.859884 [|ip]
	10:50:17.904762 [|ip]
	10:50:17.904942 [|ip]
	10:50:27.949556 [|ip]
and the ouput of ifconfig isppp0 debug
	Jun 16 10:50:58 fap /kernel: isppp0: got lcp echo req, sending echo rep
	Jun 16 10:50:58 fap /kernel: isppp0: lcp output <echo-reply id=0xa len=12
35-8d-40-7b-0-58-49-ab>
	Jun 16 10:51:08 fap /kernel: isppp0: lcp input(opened): <echo-req id=0xb
