A T-1 line will provide 1.566 mb/sec symmetrical (1.566mb going both directions).

My DSL connection is 768kb receive, 384kb sending.

With HDR, they are using a 1.25mhz channel to send a theoretical peak rate of 2.4mb/sec down to your user terminal. But, that pipe has to be shared with everyone nearby on the same cell. Therefore, HDR uses time slots to share the data pipe with others (packet switching) instead of having your own constant channel like a voice call.

If I remember correctly, the reverse link is very similar to IS95B and uses one or more channels to send data back to the base station (one channel provides 14.4kb/sec)
