Circuit and CIR charges run from $240 to $1,400 for a
T1 rate, and from $750 to $2,100 for the service's top CIR rate of 10.752 Mb/s.
A data channel can run at standard rates from 50 b/s on up to, and beyond, the
T1 rate of 1.544 megabits per second.
In addition to copper-span lines, as traditionally provided be telcos, there are three choices for local broadband voice/data transmission at the
T1 rate: fiber-optic, microwave and coaxial-cable systems.
