Abstract
1384748 Encoders SIEMENS AG 25 Aug 1972 [25 Aug 1971] 39611/72 Heading G4H [Also in Division H4] A translator is arranged to give a different code output in dependence on the nature of a calling subscriber, e.g. whether the calling is at a normal subscriber station or at a coin-box subscriber telephone. In the arrangement shown the code output produced by the operation of relays A1-A7 is independent of the nature of the caller if code points K1 or K2 are marked, but if either of code points K3 and K4 is marked the code output will depend on whether relay contacts U11- U14 or U21-U24 have been closed, the closure of the contacts being governed by a pair of "origin dependent" relays, not shown, i.e. if the calling line is from a normal telephone, contacts U11-U14 may be closed whereas if the call is from a coin-box telephone the contacts U21- U24 may be closed. The code points may relate to particular destinations to be reached by a call and the arrangement permits "origin-dependent" routing to be achieved.
