Minimum required number of lines is 4000. We also have to be able to provide "operator" Service.
This is just something that we are planning on doing, I was just asking in this list how to overcome what I
had read was a 200 Zap channel limit.
I know that this thread is OT and if someone wishes to converse with me more about it, please do it off list.
I will be posting status updates on this project (and probably asking for help) on the -users list, where this conversation now belongs.
Thanks to all of you who have helped. I am gratefully.

I should clarify, that my experience is with a retail giant's national call center, which handled 40 million calls per year by the time I left, and we had 17 DS3 coming into the building, 7 of which were idle (thank you MCI for your upselling, but I digress), and 2500 extensions, about 40% of which were assigned to actual call agents (the others were 384 VRU/IVR lines, and the rest were employee enxtensions), and probably only 60% of those active at any given time (more during Christmas season). For those doing the math, that is just under 1000 extensions active at peak times (read: complete saturation of all live agents plus all 384 VRU extensions), with reasonable estimates of maybe 100 on hold at any given time. That means 1100 incoming calls, at peak seasonal usage at the largest retail organization in the country.
So forgive me for believing that your estimate of 4800 lines needed is a bit overoptimistic....

Your poor local bus....
I guess one of the main questions people are asking, is what makes you think you need 4800 lines worth of capacity?

We are planning to use multiple Ethernet cards on the master. We were thinking three slaves/Ethernet channel.

Using slave * boxes and TDMoE. Each slave will have 5 4-port T1 Cards (20 T1's/BOX -or- 480 lines/box) We will have 10 slaves.
For a grand total of 4800 Lines.
This method was chosen for administrative ease.
You'll need Gig-E in your master server, and maybe even in your slave boxes, and a decent ethernet switch too. 4800 DS0s is a little over 7 DS3s, which amounts to over 300Mbit of traffic (not including ethernet headers) if you encode all the DSOs with G.711 uLaw (64Kbit/DSO).
