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, SW4/1 must be set to off position or a loopback test will occur. When cascading, SW6/7 must be set to on position. Cascading units must not be assigned identical or overlapping timeslots.
