Looking for a DSU

[yetanothergeek]

Current situation: We have a T1, call it T1(a) that goes to remote location A. We also have T1(b) that goes to remote location B. Each of these is terminated with a Kentrox DSU that has Add/Drop capability. We are splitting 5 channels of each of the T1's to go into a PBX (using a DA15P port on the Kentrox), and the remaining 19 channels go to cisco routers via a V.35 port.

What I'm looking for is a single DSU that will accept both of the T1's, output the 5 voice channels on T1(a) and 5 voice channels on T1(b) onto a single line going into the PBX (10 total channels), and that will also still be able to split the two sets of 19 data channels into their own V.35 ports.

I'm trying to consolidate to a single trunk card on my PBX that has the 10 remote voice channels for our two sites, rather than have 2 trunk cards with 5 voice channels each. Does such a device exist? Many thanks in advance!

I've never used these but perhaps you should look at the Adtran TSU T1/FT1 Multiplexers:

It looks like the larger units might be able to do what you need.
