I have 200 Digital Phones 100 Single Line Sets and 200 Loop Start Trunks? Can someome explained to me the configeration and how many cabients I will need? Thanks..

Well with 16 port digital cards, 16 port single line cards, and Loop Start Cards with Daughter boards, an option card, CPU you would need at least 47 slots, with 7 per cabinet, that would mean at least 7 cabinets, but I would do more for expansion, but why with that many co lines are you not doing 4-5 T1's for your dial tone? Just that can reduce it down to 4 cabinets.

Ditto what DNR said. I would really have to wonder why you would want that many POTS lines. T-1 circuits should be cheaper and would save a lot of slots.

Actually, you may want to consider going with a PRI set up. We had similiar numbers riding on a T-1 and switched via Verizon to a PRI. While set up and such did cost some money (new card for system and installation), overall we are saving about 500.00 per month. But if you go to a reseller for the card, you can save a lot of money.

You would want a 512 system, possibly with redundant CPS's with dupli-disk and dupli-disk on your VM.

Anything greater then 4 cabinets would require an ATM switch which would greatly increase the cost.
