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. |
