Abstract
1,118,589. Automatic exchange systems. SIEMENS A.G. 28 April, 1967 [29 April, 1966], No. 19596/67. Heading H4K. In a system comprising two or more exchanges X, Y, each provided with a switching network KN controlled by a marker EM, scanners T-AV, V-AV, and common control equipment ZST, if the calling party immediately after dialling, or either party in an established connection, dials a certain digit, the connection is held and the identities of the calling and called parties and of the apparatus used are stored, either in recording apparatus DR at the originating exchange or in apparatus ST at a central position Z. A data transmission link DL is used if necessary.
