Not very much for details - Looks like a Linux system with a USB
modem. The LCP negotiations reached an 'open' state

><31>Jul 3 19:40:51 pppd[835]: rcvd [LCP TermReq id=0x1]
><30>Jul 3 19:40:51 pppd[835]: LCP terminated by peer
><31>Jul 3 19:40:51 pppd[835]: sent [LCP TermAck id=0x1]

and the peer shut it down. This is usually the case where something
else important failed, such as authentication. Was there anything
in the logs between Jul 3 19:40:49 and Jul 3 19:40:51? This
extract shows the packet exchanges incrementing nicely, but where is
"rcvd [LCP ConfReq id=0x1" ?

Need more details - what is the peer you are trying to connect to?
What kind of connection is this? As this appears to be Linux, what
application are you using to set up this connection (wvdial, kppp, or
some manual script)?
