....are you saying that a fractional T1 isn't a T1?
No, he said you either get a T1 or not.
A fractional T1 is a 2pair (4-wire) circuit just like a 'full' T1, only with LESS than the 24 64/56Kbps channels not active. BTW- you get the 56Kps rate via RBS - Robbed Bit Signalling - 8K from each channel instead of devoting a "whole" DS0 to signalling information.
The CLOCKRATE is the same as a T1 though, so for example, you only have 12 channels of your T up (1/2 T1 obviously), the signalling would be:
ch01-ch02-ch03-ch04-ch05-ch06-ch07-ch08-ch09-ch1 0-
ch11-ch12-skip-skip-skip-skip-skip-skip-skip-ski p-
