[SCFN] why is T1 worth so much for 1.5 MBPS ?

[Jon Gallagher]

T1 is priced as a Telecom service. While we on the data side think of
it as a symmetrical 1.5 MB pipe, the voice side of the house thinks of
it as 24 circuits (check out the prices of a single business
circuit!). It's basically 4 copper wires that run from the CO to your
facility that carry the phone company's usual SLA (typically 5 9's).
You also pay for whatever it hooks to in the CO, whether it's data or
voice services.

DSL is multiplexed data that goes out over voice quality circuits (2
wire) and are far cheaper to provision, install, and (lackadaisically)
maintain.

If you need a SLA or QOS, you get what you pay for.
