The number of available Channel Timeslots depends on the data rate:
•
If the data rate is 1920 kbps and the framing is D&I, then only the E1 formats are available
and the Chan/TS menus are disabled. This is the ‘Fixed Channel Mode’ where all timeslots
are allocated in order. D&I++ does not have ‘Fixed Channel Mode’.
•
If the framing is D&I and Drop/Insert Type is E1-CAS, Timeslot 16 is used solely for CAS
signaling and therefore may not be allocated for traffic data.
