Any T1 I've seen in the last 3 years has actually been DS1-over-HDSL2. What comes in to the building is a single pair of copper into the smartjack, and then you have a traditional DSX1 to plug in to. I don't think "real" T1s (in the physical sense) have existed for years. Before DS1-over-HDSL2 the ones I had provisioned were DS1-over-HDSL (2 copper pairs)... never had a real, genuine T1. But again... you don't get to play with that side of it. You order a T1, you get a smartjack that has a T1 jack (DSX1) on it and what's on the other side is irrelevant. -A. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
