Reback SMS / DSL packet loss issue.

[Stephen Fulton <nanog () esoteric ca>]

Hi all,

Hope the last NANOG was good, I was supposed to go, but alas business 
got in the way.

I've got a question about an issue I'm seeing with some DSL clients.  It 
may not be limited to Redback's SMS, but that's the platform being used, 
so I won't speak in generalities.

Occasionaly clients connected via ATM PVC's experience packet loss after 
     reconnecting due to power loss.  The line sync is fine, but packet 
loss of between 40 - 60% occurs.  Only once I've used "clear sub 
<subscriber>" to disconnect the session does the packet loss stop. 
Anyone know why that would be?

I'd appreciate any insight or a push in the right direction regarding 
this, thanks.
