Not a problem at all, just make sure you have as much redundancy as possible in the server (RAID, Dual Power Supply, etc.). > > 2.

A quad port T1 gives you 96 channels, all can be used for analog stations. which means you will need at least 2 quad t1 cards. I personaly like the Adit 600 for this job. > 4.
