Abstract
1,264,722. Automatic exchange systems. SIEMENS-A.G. 17 July, 1970 [18 July, 1969], No. 34721/70. Heading H4K. In a coin-operated system, payment for each call must be made with a coin of predetermined minimum denomination otherwise the connection is broken down. This procedure is said to be adopted to save the subscriber from being inadvertently cut-off due to his inability to feed the coin box at a fast enough rate on long distance calls. The analysis of the dialled digits to assess the charging rate may be effected in the subscriber's instrument or at the exchange. In the latter case the minimum value coin to be used is signalled back by a special signal, or is determined at the subset by the interval between the first two metering pulses or is determined directly by the value assigned to the supplied metering pulses. The coin value may be set-up on a lamp indicator.
