Here's a log dump from a PPP session that ultimately collapased.
There are two sets of echo exchanges starting at 15:35 and 15:40.

Can someone explain the data in the id= fields? Also, options has the
following:
lock # use UUCP-style locking
domain omni.voicenet.com # our domain name
crtscts
modem
defaultroute
noipdefault
lcp-echo-interval 15
lcp-echo-failure 16

Why were there only two echo exchanges?
