US 4,288,658 A · Apparatus for generating telex signaling sequences in a distributed processing telex exchange

Abstract

A system for generating telex signaling sequences in each termination line in a group of customer termination is disclosed. The system includes a multi-line high-speed line control processor which transmits to and receives from each customer termination, data signals indicative of the signaling levels in the termination lines. The line control processor controls the termination signals by executing, in a time share mode, selected signaling routines for each termination. Connected between the line control processor and the customer terminations is a terminator controller means for selecting the termination currently being time share processed to input to or receive signals from the line control processor. Also connected to the line control processor is a group control processor which supervises the generation of the signaling sequences in each termination by executing script task routines. These script tasks routines cause the line control processor to execute the selected signaling routines to produce the signaling sequences required by each termination in the group.
