MPT 1327 Encoder
If the signaling command has the data codeword extension, DCW2 or DCW4,
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
When the Test Mode field is in Control mode, the signaling firmware/
hardware will cycle through the defined part of the filler buffer, transmitting each
128-bit timeslot in turn. This is shown in
figure 102 on page 411. Figure 102 also
shows the control message buffer for comparison with
figure 103 on page 413.
