Figure 74
shows that messages defined in contiguous timeslots, following the last
timeslot defined in the filler message, are transmitted between each repeat of the
filler pattern.
This can be used, for example, to insert a registration frame (ALHR) between the
normal filler frames.
The individual timeslot locations of the message buffer can be cleared by the
following command:
ENCoder:MPT1327:MESSage:CONTrol:CLEAR n
where n is the timeslot to be cleared and has the range 1 through 32.
In addition the whole message buffer can be cleared by the following command:
ENCoder:MPT1327:MESSage:CONTrol:RESET
Traffic Channel Message Buffer
This control is only available using IBASIC commands; it is not displayed on the
MPT 1327 Encoder screen.
When the RU-under-test moves to a traffic channel, the IBASIC test program
needs to stop the transmission of the control channel signaling temporarily but
still be able to send individual messages (for example, to send a
CLEAR message).
