Forward Control Channel in Control Mode and Not Sending

If the signaling command has the data codeword extension,
subsequent timeslot locations are overwritten with the data codewords. If this
results in a write to a timeslot greater than 32, the write will wrap back to timeslot
one.
A new filler pattern typically comprises several commands to be written. Since
each is written individually, the following update command is also needed to
transfer data into the working filler buffer:

ENCoder:MPT1327:FILLer:UPDATe

To complete the command set for managing the filler buffer, the individual
timeslot locations of the filler buffer are cleared by the following command:

ENCoder:MPT1327:FILLer:CLEAR n

Where n selects the timeslot to be cleared and has the range 1 through 32.
The whole buffer is cleared by the command:
ENCoder:MPT1327:FILLer:RESET

hardware will cycle through the defined part of the filler buffer, transmitting each
128-bit timeslot in turn. This is shown in
