Definity AT&T system 75 trunk change
« on: December 09, 2010, 01:21:43 PM »
Hello all,

thank you in advance for any replies.  We are not a certified Avaya dealer, however we have a customer who has contacted us to help in porting from one service provider to another.  They currently are using ground start trunks, but are going to switch to a new service with Loop start trunks.  Was wondering if anyone may be able to help us out, or point us in the right direction on getting this switched over for them.  They currently have 2 "CO Trunk TN747B" trunk cards, and are under the belief this supports both trunk types.

Any help is greatly appreciated

Thank you!
