Abstract
Enhancements introduced into an automated telephone exchange including at least one subscriber switching stage and one group selector stage, each with their own markers that typically comprise a maneuver section and an analysis section, and, connected via sets of connection relays, a series of registers for the reception of digits of the type in which the called subscriber number in the form of digit signals is received by one of the registers, stored and analyzed and sent, possibly after its conversion, to the respective markers, which in correspondence to the obtained digit information establish a connection, characterized in that the exchange includes a register arrangement (REG) common to a large number of connection establishment processes, whose arrangement consists of a logical control unit (REP) comprising an arithmetic unit, a data memory and a program memory and semi-permanent memories (ORM, AKM and KNM) for storing data connection establishment conditions, such as line selection information, subscriber category, abbreviated call tables in order to collect all the the analysis functions normally handled by the dialers, and why the recorder, in addition to the normal connection passing through the connection relay sets (RS), has a connection to the subscriber stage markers (SLM) and a connection to the markers (GVM) of the group selector stage in order to transfer maneuver information to the markers of the respective stages once the analysis of the information presented concerning the calling and called subscriber has been completed.
