Description

The solution to the object of the invention is, however, associated with this viduell, the other being ubsr centralized circuit arrangement not possible, sated. common for all system couplers, in the memory

A circuit arrangement similar to the aforementioned is located.

F i g. 1 interconnection is only that the memory in which the new device and call number essential for the invention is noted, is provided together for all part Fig. 2 and 3 details of the announcement coupler AK and subscribers with changed call numbers. of memory S.

A saving in switching means results from dialing whose new call number is to be communicated to the dialer according to a further development of the invention (Fig. 3). As a result, the message coupler from the memory closes the information about the contacts i c and 25c and places the next announcement track.

1 2 To make better use of the announcement coupler, which is responsible for connecting the lanes, the incoming lines are routed via a switching network in which 1. Circuit arrangement for automatic to the number of lines is reduced in a known manner, say of messages to callers with help S This means that it is not an announcement device with several optional successively known for the soft connection of the announcement tracks in the room - the incoming call is intended. This difficulty multiplexing in telecommunications, in particular, is avoided by the fact that the switching network with the telephone exchanges, in which, due to speech cores, an auxiliary wire ends in one of a call, at one of several announcement memory, and there according to the selected one coupler ending line is reached, and in call number the new call number is taken, which then when a call is made, the line to the announcement device speaks to the caller. The coupler runs over a switching matrix to which announcements are already known and, for example, a memory is additionally connected which contains those of British patent specification 977 917 and in the article on the telephone numbers of the selected special 15 »Autom. Intercept Service ", Bell Lab Rec. 46 (1958) 5, connections related information about the on pp. 139-149 described. These systems are implemented using time-division multiplex technology to be connected to the incoming line.
