Because you may be talking actual payload without the overhead - in that
case it would be 48 or 47 bytes per cell, depending on the encapsulation
method used...

Just try setting up a VC for DS-1 circuit emulation using AAL-1 at 3642
cps PCR and see if you can get the CSUs to synchronize. 3642 cps equates
to 1.544 Mbps raw, but only passes 1.37 Mbps of payload.
