Inventor: WATANABE KYOJI
IPC: H04L12/28
Filed: 1987-06-30
Abstract: PURPOSE:To easily and promptly execute the re-sending control by providing a bit for a re-sending instruction during a polling signal, when an error occurs at data from a terminal to load a polling and a next polling to the terminal is executed. CONSTITUTION:First, when a polling P#1 is loaded to a first terminal, #1 data are transmitted from a first terminal in response to this. Next, when a second polling P#2 is loaded to a second terminal, #2 data are transmitted from the second terminal. Further, when the second polling is loaded to the first terminal and the #1 data are received at a system side, an error M is detected. The system side provides a bit N for re-sending instruction in the polling signal P#1 to the next first terminal, and transmits it together with the polling signal. When the first terminal detects that the bit N is provided during the signal P#1, the data transmitted immediately before it are re-sent. Thus, the re-sending control can be easily and promptly executed.

Title: Burst signal transmission system
Inventor: NAWATA HIDE
IPC: H04J3/06
Filed: 1988-06-28
Abstract: PURPOSE:To ensure the reception of the succeeding burst from the head devising the system such that demodulation is applied continuously when a 3rd pattern different from a 1st pattern is detected after a 2nd pattern at the reception side and the initial mode of demodulation is transited when the 3rd pattern is not detected. CONSTITUTION:A new voice signal is inputted while a transmission station sends an end of burst(EOB) and a voice detector outputs a detection signal. The transmission station starts sending the next burst corresponding to the new voice signal from a frame next to the frame in which the transmission the EOB of the preceding burst is finished. In this case, each bit of a framing bit F is replaced by a inversion of F being the inverted pattern. On the other hand, the reception station detects the EOB to continue the fixing of the synchronization of a demodulator to await the bit inversion F at the head of the initial frame after the detection of EOB. When the inversion F is detected, the fixing of the synchronization of the detector is continued further to receive the succeeding burst. When no inverted F is detected, the synchronization fixing of the demodulator is opened and the mode is transited to the initial mode awaiting the succeeding burst.
