A communication system ( ) processes forward signals generated by headend equipment ( ) and reverse signals generated by subscriber equipment ( ). A communication medium ( ), such as fiber optic cable or coaxial cable, connects the headend equipment ( ) and the subscriber equipment ( ), and amplifiers ( ) are positioned at various locations along the medium ( ) to amplify the forward and reverse signals. The amplifiers ( ) include a dual forward/reverse test circuit (FIG. 6) having a forward test point ( ) coupled to the forward signal, a reverse test point ( ) coupled to the reverse signal, and a single directional coupler ( ) connected to the forward test point ( ), for providing the forward signal thereto, and to the reverse test point ( ), for providing the reverse signal thereto.

An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of ethernet frames and/or other data across a cable transmission network or other form of FDM transport. The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Moreover, an automatic frequency control resolves some issues of a free-running clock in an upstream tuner of the central concentrator by performing adjustments based on the average frequency error of a number of active upstream tones. In the preferred embodiments of the present invention, the automatic frequency control (AFC) utilizes a feedback loop for at least each active upstream tone. Also, the average of the active upstream tones is determined and is utilized in providing feedback to adjust the automatic frequency control (AFC).

An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of ethernet frames and/or other data across a cable transmission network or other form of FDM transport. The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Furthermore, the architecture allows a central concentrator to support a plurality of remote devices that each have guaranteed bandwidth through connection-oriented allocations of bi-directional data flows. The upstream and downstream bandwidth allocation can support symmetrical bandwidth as well as asymmetrical bandwidth in either direction. The architecture generally can be used to support connection-oriented physical layer connectivity between a remote device and the central concentrator. Furthermore, the architecture may be integrated into other higher level devices such as, but not limited to, bridges, switches, routers, and/or gateways.

A fiber management system for managing fiber optic cables within an enclosure. The fiber management system includes a trough having a plurality of slots for receiving and detachably retaining connectors of the fiber optic cables. A spool is coupled to the trough for coiling the excess length of the fiber optic cables. The trough is fixedly mounted to the inside of the enclosure to allow access to the interior of the enclosure without movement of trough without the fiber optic cables becoming entangled.

Disclosed herein are methods of providing a client with local area network connectivity and access to other services in a cable network. One such method includes: allocating bandwidth in the network to support bi-directional data communication between the host and a central concentrator. Bandwidth is allocated for a downstream flow on at least one downstream frequency channel based on a mapping between the downstream flow and a particular octet in a downstream packet. Bandwidth is allocated for an upstream flow on at least one non-shared upstream tone. The method also includes conveying a bi-directional data flow between the host and the concentrator over the allocated bandwidth, including conveying the upstream flow using the allocated bandwidth and conveying the downstream flow using the allocated bandwidth. The method also includes utilizing bandwidth in the network not allocated to data communications to provide the host with at least one audio/visual service.
