[asterisk-users] Problem with E1

[Gareth Blades]

When I had this problem I contacted digium who sent me instructions on 
how to setup the span and make a loopback plug. I then left it running 
for a while but no errors were reported.

The telco then started monitoring the line and after a couple of days 
diagnosed a faulty card in the local exchange.
