ADSL PVC Connection

Posted on 2009-02-17

Hello All,

My ADSL provider has been giving me what I believe to be false reasons as to why my ADSL service continually gets interrupted.  Each time my modem (and I've tried other modems) tried to negotiate with their server I keep getting 'PVC Connection Down'.  

PVC Status: DOWN  
Encapsulation: RFC 2364 PPPoA  
Multiplexing: VC  
Autodetect: Disable  
VPI: 8  
VCI: 35  

I've tried setting the autodetect to enable but this makes no difference.  Each time the technician attends to sort out the issue they've always got to go an 'do work' at the exchange.  What does the 'PVC Connection' actually do and why would it always be 'DOWN' when I try to connect?

    The PVC is a Permanent Virtual Circuit, which is an always ON (point to point) circuit from your ISP to your local PPP connection...  Seems there is some issues with your DSL line...  Have you/they looked at the line stats (e.g., noise, attenuation, bandwidth, errors) a/o verified the provisioning is correct???

    Thanks for the comment.  It certainly sounds to me like our ISP has seriously oversold their ADSL service for what their equipment can handle; it's not surprising for this ISP.
