I have done this before using a point to point and routes. Now I want to do this but, use one NAM. Can this be done using an existing T1 thats being used for data? Do I need a channelized T?

Site A: MICS 5.0
Site B: MICS 6.1, NAM

I will add a T1 card to both sites for the link. I want to use one NAM and possibally have site A dial out from site B.

Am I going the right route?

Thanks in advance.
