The easiest way to find out WHO IS MESSED UP is to put a piece of test equipment (that can test PRI) into the the smartjack and see if you can make and receive calls to the test set. That would determine where your problem is located.
Well I'm not understanding how he would have gotten a ring no answer then. If the D channel and B channels were out of serivce then Telco would see this down and have an alarm in their Switch. Typically you would go to a RANN.
If the system was turned off wouldn't that cause an alarm on the T1 that the PRI was riding on back to Telco. If the system is off wouldn't the the D channel and all B channels would be out of service as well?
