match the switch assignment number set by the DIP switches on the
MOM Controller Board. See CEC/IMC Digital Audio Switch
Installation, Set-Up And Troubleshooting (LBI-38938) for MOM
Controller Board DIP switch configuration details.
Table 5 maps the conventional channel allocation numbers in a
StarGate network when the maximum number of conventional channels
per CEC/IMC is set to sixty-four (64). Table 6 shows the mapping for
thirty-two (32) maximum channels per CEC/IMC. As shown in these
tables, the conventional channel allocations recycle with higher switch
assignment numbers. Therefore, when assigning switch assignment
numbers, ensure the conventional channel allocations are unique at each
CEC/IMC. For example, conventional channels should not be installed
at CEC/IMC
33 and CEC/IMC 37 if the maximum number of
conventional channels per CEC/IMC is equal to sixty-four (64).
Similarly, conventional channels should not be installed at
CEC/IMC
33 and CEC/IMC 41 if the maximum number of
conventional channels per CEC/IMC is equal to thirty-two (32).
