PRI vs T1?

[andyfram]

We have a KXTDA600 with several KXTDA0170 DHLC8 cards and ELCOT16 cards.

We are switching to a metro-ethernet voice/data solution, that function like a voice T1 (RJ45 interface).

What's the difference in using a KXTDA0290 PRI card and a KXTDA0187 T1 card? Do I need any additional cards to switch to one of these?

0290 is for a 23 channel isdn pri circuit suport Q-sig
0187 is for old school T1 circuit
either way you need an adtran ace between the smart jack
and the system
