Title: Multi-frame synchronizing method and its device
Inventor: AWAI HIROMITSU
IPC: H04J3/06
Filed: 1984-09-11
Abstract: PURPOSE:To synchronize multiple frames by a simple method, by arranging synchronizing signals of each frame in such a way that different kinds of bit patterns can be arrayed alternately and constituting multi-frame synchronizing signals where same kinds of bit patterns continue. CONSTITUTION:Multi-frames MF are constituted with an even number (eight, in this example) of frames F and each frame (F) is composed of a frame bit (a) of one bit and information bit (C) of plural bits. The frame bit (a) becomes a frame synchronizing signal. The frame bit is arranged in such a way that different kinds of bits '1' and '0' can appear alternately. The multi-frame synchronism is taken by constituting the frame synchronizing signal so that the pattern of the frame synchronizing signal of the first frame of each multi- frame MF can become equal to the pattern of the synchronizing signal of the end frame of the last multi-frame MF and detecting the continuation of the frame synchronizing signals having the same pattern. Therefore, synchronism of multi-frames of time division digital transmission can be taken without lowering the quantity of transmitting information.
