Broadband service drop of one point pair poly dots which possess the multiplex time slot return channel for the device inside the customer house

(57) Abstract The remote site in the communication system the screw which the shield is not done through the multiplex drop communication link which is formed to the opposite which is bent it is joined to the optical network unit which is jointed to optical fiber link. The main site (10) from through optical network, one point pair poly dot communication modes have been given the wideband data signal which is linked to the lower part in order to give the return message from the carrying and that remote site to the remote site. If you follow this mode, as for the high-level transceiver in optical interface unit 1 or ahead the wideband data signal and the respective oriented which are directed to the remote site above that the remote site and relation, the STS1 frame which includes the control code which displays the slot of the return time which is attached through multiplex drop communication link, is transmitted to the remote site. Regarding the remote site, the downstream transceiver to slot of upper part link through the generating line return channel which is converted, returns in order to control the time of transmission and utilizes the control code which displays the slot of time.
