Abstract
PURPOSE:To realize inexpensive and stable-operation circuit constitution by making a connection between a branch board control processor controlling all branch boards and a signal control processor for repeating control over every block via a transfer line for periodic information and aperiodic information. CONSTITUTION:Information regarding signal control over extension telephone sets 200-208, and trunk circuits 220-228 is transferred from signal control processors 260-262 to branch board control processor 290 controlling branch boards 203- 208, and processor 290 gathers and edits the information to divide control instructions to branch boards into common information among all branch boards and individual branch board control information. The common information is transferred from processor 290 to processors 260-262 via periodic information transfer line 298, and the individual information via aperiodic information transfer line 297. Consequently, an economical and stable-operation circuit can be constituted, without exerting a great influence on the traffic of the information transfer lines, for an automatic exchange equipped with extension telephone sets, and many large-capacity circuits such as trunk circuits and branch boards.
