                       MISCELLANEOUS TECHNICAL NOTES

  Timeslot switches are ignored in unframe mode. In framed mode, clock
  rate is determined by the number of timeslots enabled ( n ). In CAS
  mode, SW3/1 must be set to off position or a loopback test will occur.
  Cascading units must not be assigned identical or overlapping
  timeslots.
