the user device with multi time slot on the basis of the return channel with the two multipoint broadband services drop

摘要

in the communication system, the remote site has not been in the shield in turn by the multi drop communication link through the optical fiber link in the optical network port is in connection. the main site (10) to the optical network links a broadband information signal to a remote site to the remote site, and from the return information to deal with in order to point a multipoint communication system is provided. according to this method, the optical interface of the streaming media in the city is more than 1 time in the remote network to broadband information signal containing the STS - 1 frame and multi drop communication through the remote site destination associated with a typical return time the control slot the code to the remote site.the remote site, and a flow control for a long time. it is representative of the return time slot control code, and use the link in the slot of the return channel on the transmission time of the control.
