The typical questionnaire we send out for the telco at the site to fill out is as follows but if the site isnt knowledgeable or not sure about their system they cant give me the info :)

1. Do the A and B bits always change together during signaling?
2. What is the initial state of the A and B bits?
3. Does the CO expect A,B,C and D bits or just A and B?
4. Does the CO expect a bit pattern to be transferred when the line is idle?
5. When the CO detect an incoming call, what changes are made to the A and B or A,B,C and D bits to indicate this?
6. After detecting a call, does the CO expect a "wink?" What bits are changed to indicate the Wink, and how long should those bits be changed for before reverting?
7. Does the CO send ANI digits and/or DNIS digits?
8. What is the maximum # of ANI digits that will be sent (including prefixes/suffixes?)
9. What is the maximum # of DNIS digits that will be sent (including prefixes/suffixes?)
10. Which is sent first DNIS or ANI digits?
11. What is the prefix sent before the DNIS and ANI digits?
12. What is the suffix sent after DNIS and ANI digits?
13. Get an example of ANI digits with suffix and prefix.
14. Get an example of DNIS digits with suffix and prefix.
15. After DNIS does the CO expect a wink?
16. After ANI does the CO expect a wink?
17. Does the CO need a "RingBack" from the Dialogic card before answering the call?
18. What bit changes does the CO want in order for us to indicate a call answer?
19. What bit changes does the CO use to indicate a disconnect?

I;m going to see if they have a crossover cable being used or not. Its kind of difficult because they are saying they cant do anything because it works fine on the old Brooktrout cards the lines were plugged into. I really appreciate the help guys.
