I don't want to start the How many calls can Asterisk handle? discussion or How many angels can stand on the point of a pin? discussion either. But can anyone contribute some practical knowledge of systems that take in channel bank T1s or DS3s from far away, and process the calls? I am looking

Yes. Adtran makes excellent gear. The MX 2800 is good for breaking a channelized DS3 into PRIs. Thanks, will look at that. Ah, a DS3/T1 mux. I was looking for a DS3 PC Card... it would have 672 channels but the system doesn't need to handle but 20% of them at one time. If you're just
