Hello, We recently replaced our TC1000 with a newer model. The goal to upgrade so we can offer V.92 and perhaps to eliminate some hardware failure trends that we were seeing on the old box. Now that the newer chassis is installed we are seeing connection success rate falling and are not understanding the V.92 modem process. Our techs have reached their limits. We suspect that the box is trying to fullfil V.92 requests but something is wrong in our configuration and causing that V.92 attempt to degrade the users experience (slower connection) then when we only offered V.90... Small Rural VT ISP Is there an experienced user on this list that can be contracted for remote review of our configuration and perhaps optimising/troubleshooting our Total Control? Naturally we would need a few references before we 'open the door' on a remote connection. Thank you, David Covell --- Outgoing mail is certified Virus Free.
