Surely you jest.  A C30 IMP couldn't handle a T1 rate.  Most IMPS
run either at 56kbits or 9.6kbits (In Europe).  BRL I believe runs
their's a bit over 100 kbits.  T1 is in excess of 1Mbits.  I would
guess (I've never worked for a BOC or AT&T LongLines) that the 56kbit IMP
trunks are one of the channels that a T1 is divided into.
