Abstract

PURPOSE:To economize a talkie sound supply system in a time division exchanger, by distributing the talkie sound in the time division multiplex mode to each circuit through a time division switch for a talkie sound signal via a common talkie trunk. CONSTITUTION:When a request of talkie service is produced from an incoming trunk 2A, a controller (not shown) selects a common talkie trunk 5. By setting a channel 1 through the control of a time division switch 1', a path of an incoming trunk 2A, D/A converter 3A, time division switch 1, A/D converter 6, common talkie trunk 5, and announcement machine 4 is finished to supply a desired talkie sound signal to the incoming trunk 2A. When the request of the same talkie service is produced from an incoming trunk 2B, a channel 2 of the time division switch 1 is set and the same talkie sound signal is distributed to the incoming trunks 2A, 2B in time division multiplex.
