My D Channel seems to go up and down.
Check to be sure you have set your timing parameters correctly. Also
check the common causes of problems for a T1. See the Common Fixes
for all cards, page 47.
I have trouble dialing out. It seems that one type of dialing works
(local, long distance, international) but another does not.
Check your
pridialplan
variable and be sure that you are dialing using the
method your telco is expecting.
I am having trouble receiving DID information over E&M.
Try the other types of E&M (featd, featb, etc.) to match the method your
telco is using to stream information.
I am having issues with my PRI. How can I see the messages coming
across my D channel?
Enter the following command:
PRI debug span X
where x is the port from which you are connected. This command will
show you the PRI messages coming across your D channel for that
message.
