I am in need of vender names, phone#numbers and description of their T3 products. I need a box to sit on either end of a fiberoptic cable and make ~24 T1 channels. Can anyone recommend such a beast? Thank you, Ron Watkins

T3 is 28 x T1 (or 7 x T2, if you prefer). Try Telco Systems (the Norwood MA site, not the CA site - same company, different product ranges). Their 828 family of products will do it. Also their FOX-2 will take T2 (4 x T1) via fiber from the 828s to some other site (another floor, or another building in an office park, etc.) NTI's FMT-135 does up to 3 x T3 with various inputs, and the smaller DTM-300F does one T3 from seven DS2 streams. AT&T DDM-1000 does 2 x T3, and can mux both onto one fiber at 90mb/s if you prefer. The Rockwell/Collins DML-3x50 does one to three T3s onto fiber. Rockwell/Wescom has a Digital Crossconnect System that can serve up to 128 T1s and crossconnects at the DS0 (64kb) level. You need a large distributor that has a department that specialises in this stuff, and that carries a lot of competing products, so you know that they are not biased towards just the one product a smaller outfit be pushing. Try ALLTEL at 1.800.533.3161, or Anixter, or North Supply, or even Graybar. There are more brands and models and suppliers, this should get you started.
