isdn PRI NT1 vs NT2

[gblackburn]

A customer was asked while placing a PRI order whether they would prefer NT1 or NT2 on their PRI. Which would be appropriate for a NM-hdv interface that will be defined as an h.323 gateway?

Network termination type 1 (NT1)—In North America, the NT1 is provided by the customer. In most other parts of the world, the NT1 is part of the network provided by the ISDN service provider. WAN interface cards that do not have an integrated NT1 must have an external NT1 in order to connect to ISDN services.

Network termination type 2 (NT2)—This more complicated device is usually found in digital private branch exchanges (PBXs).

I would say that the customer should ask for NT2.

Thanks for the response. I suppose the question at the heart of the matter is does the NM-HDV support the NT2, and is there a good a good white paper on the subject? Thanks.
