We have two AdTran 600s which works with two Cisco 1600 series routers to connect two sites over a point-to-point T1.
18 channels are configured for data.
6 channels are configured for voice.
The T1 comes from the SmartJack at each end and goes into the Network port on one of the AdTrans.
The v.35 card in the AdTran connects to the Serial port on the 1600.
A DSX card on the AdTran connects to a T1 Interface card on the PBX.
We want to eliminate the AdTrans and have one router at each end receive the T1 directly from the SmartJack and hand off the 6 channels to the PBX.
From a (somewhat uncertain) call to Cisco pre-sales, I was told a VWIC2-2MFT-T1/E1 card is needed for this to work, and that will only work in a 2801 or better.
Is this a fact?
Is there no way to make the equivalent of the DSX connection to the PBX using, say, a 1720 with a WIC-T1 w/integrated CSU/DSU and some other card to manage the short-haul to the PBX?
If not the 1720, perhaps an 1841 or other model?
