[CLUE-Tech] OT: DSL QoS Revisited

I've had my Qwest DSL service for almost three months now. My
opinion is the service is adequate, but not as reliable as AT&T
Broadband was for me.
I've noted frequent drops in my PPP link to my upstream provider.
Initially I attempted to review the logs in my Cisco 678, but was
dissappointed to find it only stores 40 entries. I've recently
configured it so use syslog on one of my *nix boxen and have captured
a few days events.
The logs are appended below. The frequent drops I refer to are the
"PPP Down Event on wan0-0" entries. Sometime's the link is down
for only a minute. Other times it is down for an hour or more.
FWIW, I never observed this sort of behavior with my cable modem. That
is an opinion based entirely on anecdotal experience, I don't know if my
cable modem could log any information. It was operating in bridged
mode, so my FW box did the negotiation for my IP. I just don't recall
any daily outages.
The logs only provide minimal information. Is anyone aware of a means
to collect more descriptive output from the Cisco 67x series?
I took a look at the CBOS doco, but I don't see any option to change
the verbosity for logging. I know Dave A. had a thread going back in
October on DSL QoS, where he was inquiring on troubleshooting the
PPP over ATM connections between a customer endpoint and the upstream
provider.
Dave, have you had any luck since October?
Does anyone have any suggestions?
I have sent theses logs to my ISP along with an inquiry.

Cheers!
