Embodiment Construction

[0023] The diagram describing the general structure of the present invention is as figure 1 as shown, figure 1 Can be subdivided into 4 groups. The first group is the headend equipment 100 for cable TV. The second group is a Hybrid Fiber Coax (HFC) distribution network 200 . The third group is premises coaxial distribution equipment 300, which can be used both in MDUs and in similar situations, such as hotels. The last group is the devices 400 in the user's room. Group 300 and group 400 include elements of the present invention. In keeping with industry practice, cable TV headend and Internet are for cable TV and IP data respectively figure 1upstream end. A television or computer in a user's room is a downstream point. Uplink data transmission goes up to the upstream end. Downstream data transfers downstream to the downstream end. Thus, an element on a data path receives downstream data transmissions from its upstream end, and upstream data transmissions from its down...

Abstract

A system and method of compensating for path losses for data transmissions from various remote modems (408) to a central modem (332) for use in a system that provides data communications over a passive multipoint network such as coaxial tree and branch cable television distribution network (320). The central modem (332) communicates to remote modems (408). The remote modems can be placed in communication with a downstream device (such as a personal computer) (420) to allow the downstream device (420) to communicate with the central modem and ultimately with a wide area network such as the Internet (504).
