Would you reccomend N1 or N2?
Also, do we need a CSU, and if so which brand and model do you reccomend.
Thanks

As far as the D-channel protocol, we usually use NI2, unless the carrier doesn't support it. Then we use 5ess.

Correct me if I'm wrong; but doesn't the T1\PRI card take care of required needs. | | | | | Joined: Dec 2004 Posts: 5,722 Member | | Member Joined: Dec 2004 Posts: 5,722 |  !!!

And, it did not work!
Grrrr
