Anyway, since the bits in robbed-bit signaling are "robbed" from the
superframe not from your DS0, it is irrelevant to your throughput.
This is actually not correct; my memory was at fault.
Robbed bit swipes the 8th bit of each timeslot during the 6th and 12th frame
for superframe; the 6th, 12th, 18th, and 24th frame for ESF.
Of course, you would not be reading this right now had
cskidmor@nwnexus.net not taken the liberty of re-adding NANOG to the
cc: list after I explicitly stripped it and sent personal mail in an
effort to keep the noise down on the list. :)
