[Asterisk-Users] PRI questions

[firedude at shorelinuxsolutions.com]

We are in the prossess of ordering a ISDN (PRI) line from Verizon.  There 
are a couple of questions on the application that I don't understand.  I'm 
still a newbie here but we're taking the big plunge.  If someone could 
give me some direction here I would be greatly appreciative.  The  
questions on their app that I don't understand are:
1.) The Verizon Co will outpulse 10 digits to the PBX, is this 
satisfactory?

2.)DNLS Digit Dialing - Prefix and Delete - (if yes, what will it be?)

It's also asking for the PBX manufacturer / system model number and the 
PBX software / release.  Should I just fill in Asterisk and the realease 
for these questions?

Lastly, they wish to know if it is custom or national ISDN and if its 
national - if it is 1,2,3.  How do I determine this?  
Thanks for any and all help.
