Hello All, I was wondering if I could do the following on asterisk... Get a T1 between 2 locations, and split it into a data channel of like 1024, and use the rest for voice channels. Has anyone done this and had it working well? Or would I need to get a csu that allows a split into two interfaces? Regards, Greg

Since you posted to this list I assume that * is used at least on one end of the t1. If you use good routers that can prioritize voip traffic then all you need is ata's and/or ip phones at the other end. That gives you more data bandwidth when the phones are not in use. Segregating n/24 of your t is not so flexible.

I get standalone adtran t-1 routers > for about $650 in qty 1. >No doubt about that, not sure why the Greg wants to do what he is asking for, personally I would use 2 used Cisco routers with integrated T1 DSUs and priority queuing for VoIP, assuming VoIP phones at the remote location. That would be about $600 for qty 2 on ebay! I just assumed Greg had a need for a T1 TDM interface on both ends.
