A tunnel rebuild is just re-establishing this link, generating a new pvc from the IPSN to the cmux. Nothing physical. The process would take someone who has 4fingers and 1 thumb on each hand about 1-2 minutes to do, after that is done, there's a delay with the IPSN updating what pvc ids it will let in, you'd probably get auth failed or some such until it updated (usually every hour). It should not take a week, though there are sometimes some outside factors that will not allow the pvc to be regenerated, but my guess that would happen rarely. Sounds like Netspace didn't get many meaningful SLAs in it's agreement/contracts with Telstra :) Why does it happen? pppoe is a dodgy protocol, broadcast protocols running through it it, like udp and such, can cause the ppp session to lockup and reset. This disconnection of the pppoe session should not however cause a problem with the tunnel. Blame nortel, or alcatel, or telstra, or all three, maybe even the easter bunny as well. Probably nortel though, the atm pvcs lack of traffic flow is most likely caused from the IPSN end of thing, as it provides you the ppp session. -dan "DavidR" wrote in message news:3c99ae91@news.comindico.com.au... > What is done when the 'tunnel is rebuilt' in reguards to netspace adsl. > Should it take a week to get done? and why would winxp create a fault that > would require a tunnel rebuild for me to get back online? > > Thanks > DavidR > >
