data channel - Free On-line Dictionary of Computing (26 May 2007) :

  data channel
  
     <communications> A channel (on a BRI or PRI line) used to
     carry control information, to set up connections on the
     associated bearer channels.  The name wasn't too bad back
     when users were sending voice (not data) over the bearer channels
     , but in 1997 it's quite a misnomer.
