Actually there is a nice little trick you can pull to meet the
ones density rules for a DS1 circuit.  If you are running
HDLC or SDLC framing on your data all you need to do is invert
the sense of the ones and zeroes and the HDLC bit stuffing
takes care of it.  This can easily be done if you are using
a V.35 (balanced type) interface by frogging the TD and RD
pairs at each end of the cable.
