	Really?  What do you call T1 carrier circuits which run over pairs
in regular telephone cable (adjacent to other circuits) at 1.544 Mbits/sec?
Bring an AM radio into an equipment room with a T1 span line and tell me
what you hear at the high end of the dial.
	Incidently, within telephone company central offices T1 circuits
are run separate from all other circuits using either individually-shielded
pairs, or in dedicated multi-pair cables (usually of a type called ABAM)
having a common shield.
