Synchronous transmission control system

Abstract

A synchronous transmission control system is provided which comprises a first-in/first-out stack storing plural kinds of synchronous pattern signals, a comparator for comparing the synchronous pattern signals with the synchronous pattern signals delivered from a transmitting side, and a controller for switching the data flow in the stack in response to the output of the comparator, in which the comparison of the respective synchronous pattern signals stored in the stack with the synchronous pattern signals delivered from the transmitting side is carried out in the comparator, and, if the comparison shows coincidence between them, the data transmitted from the transmitting side is permitted to enter the receiving side through the stack, with an assumption that synchronization is established between the transmitting and receiving slides, while, if the comparison shows disagreement between them, a synchronous error control is executed.
