Abstract

1,122,924. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 8 Sept., 1966 [14 Sept., 1965], No. 40127/66. Heading H4K. An exchange has one network A 1 , B 1 for setting up speech connections for telephone subscribers and has a second network A 2 , B 2 for setting up telegraph connections for teletypewriter substations, control circuits such as an identifier, translators, fee rate and dial pulse receiving circuits, being common to both circuits. Both telephone and teletypewriter substations may also have data sets and, to enable a data set in one network to reach a data set in the other network a coupling stage C is employed. The networks have ferreed crosspoints.
