Problem with ppp Serial Link

Unanswered Question

Hi all,

I have a 64K serial link using ppp encapsulation connecting a remote site from a central E1. The central E1 serial interface is showing up/down while the remote interface is up/up. I am able to ping the p2p interface in the remote site using my backup link to the site but cannot ping p2p interface in the central site hence the overall p2p connectivity on this link is down. Could someone offer some explanation for this?

The circuit has probably too many errors to work in PPP (fails negotiation), although it might marginally work in HDLC. In any case, you need the circuit repaired.


Hope this helps, please rate post if it does!
