Title: Arrangement and method for the localized self-control of randomly allotted time slots to audio ports

Abstract: An arrangement and method for the localized self control of randomly allotted time slots to audio ports wherein simple control circuits with a memory are dedicated on a per audio port basis. A common control writes into the memory the time slot identity allotted to an audio port. The time slot identities generated by a channel counter are made available to all of the audio ports in the system, and a comparator in the control circuit associated with an audio port compares the stored time slot identity with the variable or varying time slot identities. An audio port is turned on and off without external control every time the two identities match. With this arrangement, any number of audio ports can have the same time slot identity, all turning on and off simultaneously in the same time slot to share the transmission medium.
