PROCEDURE FOR THE OPERATION OF TEMPORARY TELECOMMUNICATION SWITCHING FACILITIES CONTROLLED BY CLOCK IMPULSES, ESPECIALLY TELEPHONE SWITCHING FACILITIES-PCM, WITH CENTRAL COUPLING FIELD AND PARTIAL COUPLING FIELDS.

摘要

THE CONNECTION GROUPS, WHICH HAVE A CENTRAL COUPLING FIELD, CONNECTED TO EACH OTHER THROUGH MULTIPLEX TIME LINES, AND WHICH, IN ADDITION, HAVE A PARTIAL COUPLING FIELD AND A COMMAND CIRCUIT FOR GROUPS, MUTUALLY CORRESPOND TO THEMSELVES. THE CONNECTION DEVICES INDIVIDUALLY ASSOCIATED WITH ONE OR THE OTHER OF TWO CONNECTION GROUPS ARE CONNECTED IN THE NORMAL OPERATION WITH THE PARTIAL COUPLING FIELD OF THEIR OWN CONNECTION GROUP AND CAN BE CONNECTED WITH THE PARTIAL COUPLING FIELD OF THE OTHER GROUP. BOOKING OPERATION. DUPLICATED COMPENSATION MEMORIES ARE PROVIDED IN THE CONNECTION DEVICES FOR THE INFORMATION FLOW OF AND TO THE OWN PARTIAL COUPLING FIELD AND FOR THE INFORMATION FLOW OF AND TO THE PARTIAL COUPLING FIELD OF ITS PAIRED CONNECTION GROUP. THE COMPENSATION MEMORIES RECEIVE THE CLOCK DRIVE OF THE PARTIAL COUPLING FIELD TO WHICH THE INFORMATION IS TRANSMITTED. THE FIRST COMPENSATION MEMORIES RECEIVE THE CLOCK IMPULSE FROM THE OWN CONNECTION GROUP, WHILE THE SECOND COMPENSATION MEMORIES RECEIVE IT FROM THE CONNECTION GROUP MATCHED WITH THEM.
