Abstract: An accurate non-Data Over Cable Service Interface Specification (non-DOCSIS) clock signal is generated at the downstream output of a DOCSIS network. In one example method, a downstream DOCSIS Timing Protocol (DTP) client in the DOCSIS network is frequency synchronized to an upstream DTP server in the DOCSIS network. DOCSIS timing information, along with one or more timing correction factors received at the DTP client, is used to time synchronize the DTP client to the DTP server. Based on the time and frequency synchronization between the DTP server and the DTP client, the clock signal is generated at the output of the DTP client in accordance with the non-DOCSIS timing protocol.

Abstract: According to one example embodiment, a modem or other network device include an energy module configured to enter a low-power, low-bandwidth state when not in active use by a user. The low-power state may be maintained under certain conditions where network activity is not present, and or when only non-bandwidth-critical traffic is present. The network device may include a user interface for configuring firewall rules, and the user may be able to concurrently designate particular types of traffic as important or unimportant. The energy module may also be integrated with a firewall, and power saving rules may be inferred from firewall rules.

Abstract: A location of a client device may be detected. From a first location, a first angle from a first reference line to the client device may be determined using beamforming. Next, from a second location, a second angle from a second reference line to the client device may be determined using beamforming. The first reference line and the second reference line may be parallel. Then, an intersection point of a first directional line and a second directional line may be determined. The first directional line may be defined by the first location and the first angle. The second directional line may be defined by the second location and the second angle. A client device location corresponding to the intersection point may then be obtained.
