The 10-Channel Audio Network Board provides up to 10 audio channels in a distributed network of T3-SC Systems. It is used in applications where more than a single channel of voice communications is required between systems on the T3-SC Network. 

Additional channels are added to the network on a global basis. In this way, any Console can utilize an available audio channel to access the intercom stations or paging speakers of other T3-SC Systems. Up to 10 intercom conversations or paging announcements, or a combination of both, can take place simultaneously over the T3-SC network.
