voted and that transmitter 8 is active. Both of these states will be shown on the
operator’s PC.
To force the TSAM to steer to transmitter 1, the operator will generate a FORCE
VOTE for receiver 1. The TIB will receive this FORCE VOTE for receiver 1 and
setup the Tx Select lines for transmitter 1 and the Force Select line. When the
TIB activates the Force Select line to the TSAM, the TSAM will immediately
steer to transmitter 1. The FORCE VOTE for receiver 1 will also cause the CIB
to generate a FORCE VOTE command to the comparator.
9.2 Multiple TIB/TSAM System Example
Figure 9 shows an example system that has 16 receivers and transmitters on the
same communication channel. Therefore, 2 TIBs and 2 TSAMs are required
because each only supports 8 transmitters. In Figure 9, the console audio
connections were omitted to keep the diagram simple. Normally the console
audio paths would be connected the same as shown in Figure 8.

Figure 9 - Multiple TIB/TSAM Example
For the system shown in the figure, note the following:
• Comparator 1 and TSAM 1 control receivers 1 through 8 and
transmitters 1 through 8 respectively.
• Comparator 2 and TSAM 2 control receivers 9 through 16 and
transmitters 9 through 16 respectively.
