hi NG,

i'm running a ASA 5505 and loosing the connection every so often.
The DSL Signal is not an issue, since my Zywall2 works properly in
combination to my DSL-Bridged-Mode Router.
The Bridged Mode Router is a: Zyxel p623me-t1, where by the ATM loopback
test is OK, noise margins up/down seem ok as well.

While running the ASA after around 25-40 Minutes i get following messages:

%ASA-3-403503:PPPoE:PPP link down:
%ASA-3-403503:PPPoE:PPP link down:Peer Terminated
%ASA-3-403503:PPPoE:PPP link down:
%ASA-3-403503:PPPoE:PPP link down:LCP down
%ASA-3-403503:PPPoE:PPP link down:
%ASA-3-403503:PPPoE:PPP link down:LCP down
%ASA-3-403503:PPPoE:PPP link down:
%ASA-3-403503:PPPoE:PPP link down:Peer Terminated
%ASA-3-403503:PPPoE:PPP link down:
%ASA-3-403503:PPPoE:PPP link down:LCP down

My ASA now will hardly ever reconnect again, without me rebooting the
Bridged-Mode-Router.
Following shows a sample of a debugged connection etablishing and connection
failing
I asume not the link is the issue, i could be something about diffrent
PPP(oE) timing...
any suggestions are welcome.

thank you
