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).
