    • A two-way hybrid fiber-coax cable networks offering high-speed broadband communications delivered via a cable modem service. Bi-directional transmissions of packets between the head-end controller (Cable Modem Terminal System) and cable modems (subscriber terminal units) is accomplished using a cable television Media Access Control (MAC) protocol. In Hybrid Fiber-Coax (HFC) networks, the invention provides a Reverse Path Multiplexing (RPM) function permitting the coupling of a large number of return path (plant) RF ports (return ports) to be coupled to a receiver card in the CMTS. One aspect of this invention is that one or more upstream traffic schedulers reside within the CMTS equipment with the responsibility of scheduling the upstream transmissions from cable modems. The cable modems are distributed across many return ports. The data from each cable modem must be successfully received by the head-end controller without being compromised by the effects of noise funneling. The knowledge of when a cable modem will transmit is used to open an RF switch in the RPM.
    • 双向混合光纤同轴电缆网络,通过电缆调制解调器服务提供高速宽带通信。 前端控制器(电缆调制解调器终端系统)和电缆调制解调器(用户终端单元)之间的数据包的双向传输是使用有线电视媒体访问控制(MAC)协议实现的。 在混合光纤同轴(HFC)网络中,本发明提供了反向路径复用(RPM)功能,允许将大量返回路径(工厂)RF端口(返回端口)耦合到CMTS中的接收器卡 。 本发明的一个方面是一个或多个上游业务调度器驻留在CMTS设备内,其负责调度来自电缆调制解调器的上行传输。 电缆调制解调器分布在许多返回端口。 来自每个电缆调制解调器的数据必须由头端控制器成功接收,而不会被噪声漏斗的影响所影响。 电缆调制解调器何时传输的知识用于打开RPM中的RF开关。
