I am new to cisco, but am a quick learner. I have a customer with 2 remote locations that have point to point t1,s connecting them. currently i have the t1's going right into the csu on the phone system at each location. Can i de-channelize the t1 using a cisco 2600/or 3600 with (4)csu/dsu's at the main location and 2 at each of the others? My vision is that i could assign 10 channels to the first csu/dsu at each remote location for data and 13 channels to the second csu/dsu for the voice. then at the main location i would have 2 csu/dsu's assigned 10 data channels and 13 data channels for the 2 voice csu/dsu's. is this an option using csu/dsu's or does cisco use a different wic for this application? some basic config items to remember would be appricated. I have configured a cisco router to 2 locations before for data traffic only, so i do know some of those basics, but dont know how to split channels. thank you all much in advance.

woodsey,
..i think you are going to need a device at each of customers remote location that will take that T-1 and break off x amount of channels for the pbx and router..
...could it be an adtran?..i think it is
...then simply config the cisco router for 10 channels..no problem there...
...dont think there is any other way to do it...
..comments suggestions...

CSUs (Channel Service Unit) do not typically breakout DS1 channels. That function is performed by another device like an Adtran TSU-120e or Netvanta 3200/3300 series equipped with the appropriate Network Interface Module or a Cisco Access router that has multiple WIC slots to accommodate connections to multiple DS1s and the software to support drop/insert channel functions. There are even some Channel Banks that perform some or all of these functions also.
Hope this helps!

Hi woodsey,
Not sure if this is relevant or not (I am based in the UK and have E1 as opposed to T1) but I work for a data and telecomms company. When we are splitting an E1 circuit for voice and data (the voice coming direct from a cassette/ blade in the PBX and the data coming from the LAN) we use a device called a Multiplexer... it is designed for this purpose and allows you to "split" the E1 circuit into 30 64K channels of which you can allocate x amount to data and x amount to voice....
Sorry to ramble but hope the suggestion is useful
Regards
