| 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. |
