Abstract

PURPOSE:To reduce busy calls, by providing extension routes as well as basic routes with trunk groups of an exchanger making talkey service in connection with a plurality of various talkey sound sources, and connecting the basic routes with them in matrix connection. CONSTITUTION:Basic routes 0-n consisting of trunk groups TKT0...TKTn are provided amount an exchanger X and talkey sound sources TKE0...TKEn and extension routes 0-n consisting of trunk groups TKT'0...TKT'n. A matrix switch MS is provided between the basic routes 0-n and the extension routes 0-n to enable the connection among the routes. When the number of talkey power supply TKE is called out with a subscriber telephone set TEL, a common controller MKR transmits the number to a translator TLR'. The TLR' first obtains the vacant trunk in the basic routes and second in the extension routes, transmits the numbering information to the common controller MRK to connect the subscriber telephone set TEL to the vacant trunk. Thus, the busy calls can be reduced and the installation cost can be decreased.
