Abstract

PURPOSE:To increase the number of subscribers requiring simultaneous communication by connecting another trunk unit to an overflowed subscriber through a channel network in case that the number of subscribers has overflowed the specific trunk. CONSTITUTION:Trunk units TRK1, TRK2...TRK2...TRFn are connected to the output terminal side of a channel network, for example, through lines LN0, LN1... LN15 respectively and perform the call processing. In case that these units TRK1... TRKn receive a special number of simltaneous communication from orginating subscriber SUBA and perform the simultaneous communication to subscribers SUBB1...SUBB16, unit TRK2, etc., are connected in chain through the channel network and this line is used to transfer the call for overflowed subscribers to unit TRK2, etc., and perform connection processing if the number of subscribers has overflowed unit TRK1 and unit TRK1 cannot perform connection processing. As a result, the number of subscribers requiring simultaneous communication can be increased.
