Channelized DS3 stuff only seems to be useful for putting mulitple customers on a single physical circuit. You need to be able to break it out to the DS1 level for each customer. Perhaps MFS, PacBell, etc can do this? It's probably just a matter of them defining that "product". (I.E. Feed MFS a DS3 and they give a T1 to each of your customers.) --Ben Kirkpatrick Data Products, Electric Lightwave, NOC= 800.622.4354 -not speaking for ELI, not even speaking- "Consciousness: that annoying time between naps."
