I'm diagnosing a problem related to PRI card. I would like to know the following: assuming I've got a working PRI card and correctly installed Linux drivers and a PRI line connected to the card, even without starting asterisk, shouldn't I hear a ring tone when I dial the number? I'm getting busy tone all the time.
Without a a correctly coded q.931 conversation driven by a program the central office is likely to (should really) consider the line down and signal an error. If you tried phoning from an isdn equipment you would likely see a cause code that explained the situation better.
First make sure that the lower level is connected correctly. Run zttool
and make sure you are not seeing a local red alarm or any remote alarms.
You may need to start Asterisk to get the span started, I am not sure.
When zttool shows the span to be up you can start working on the upper
layers.

Just a warning, based on my experience with NTL here in the U.K.
Even after you have zttool and asterisk running and happy, you may still not have
a working system.
Whilst setting up asterisk I had triggered so many alarms on NTL's monitoring
screens that the ops guys had marked the line as out-of-service just to
shut it up !
This meant that no calls could go in or out, even though the interface came up fine.
When I rang support they quickly put it back in service and things started working.
Tim.
