[cisco-voip] Checking hardware -- PRI

[Wes Sisk]

line code , path code, and err seconds are L1 issue.  you are not 
maintaining sync on the T1.  This can happen if your clock source is 
incorrect.  this is similar to speed/duplex mismatch on eth interface.

'multiframe established' is L2.  L2 will work only when L1 is working.  
this is like getting an IP address on an eth interface; it might happen 
with a speed/duplex mismatch, but it might not.

you've got errors at L1.  Did anything in house cabling change?  You can 
use a t1 loopback to test the vwic. There are software commands for 
loopback and a hardware loopback plug.  Otherwise, it's circuit fidelity 
between you and wherever the T1 terminates for your provider.
