Henning, no one can accuse you of being a Bell-head!  The terminology comes
from the TDM network, where sometimes the user gets to use all 64000
bits/second (8 bits x 8000 samples per second), and sometimes network
equipment steals the low-order bit for low-level signalling (hence the user
only gets 7 bits per sample).  In ISDN signalling it is at least possible to
ask for 64 kbit/s clear channel (8 bit clean channel), but you won't
necessarily get it.
