A controller arms an alarm aspect of a corresponding security system. The corresponding security system is initially configured to audibly activate an alarm in response to detecting motion of free-to-roam entities in a monitored location. The free-to-roam entities can be provided unrestricted access into the monitored location. In addition to monitoring for presence of motion at the monitored location, the security system monitors the location for presence of a disarming device. At times of detecting presence of the disarming device at the monitored location, the security system prevents activation of the alarm based on detecting the motion of the free-to-roam entities.

The present invention teaches methods and systems for monitoring and controlling bandwidth usage between an internal local area network and an external network. By providing controls from inside the external network connectivity point, greater detail in bandwidth control is possible. This in turn leads to less restrictive bandwidth restricting algorithms. Bandwidth restricting algorithms include various bandwidth limiting techniques. One such technique uses prioritized data transfer limits applied on an application, process or network interface basis. Another technique uses a configurable weighting factor for real-time prioritization of data traffic. Other techniques incorporate quality of service or model predictive control based bandwidth limiting.

The detection of devices with duplicate media access controller (MAC) addresses in a cable network may be accomplished by reference to a value indicative of a DOCSIS version supported by the device or by reference to a having a MAC address/giaddr pair. Where a version value is used, the detection of devices having duplicate MAC addresses looks for changes in the reported version value from a higher version to a lower version. Where MAC address/giaddr pairs are used, a centralized storage of historical cable modem MAC address/giaddr pair data is used to identify cable modems (CM's) that report duplicate MAC addresses. If duplication is detected, an appropriate remedial response is taken.

A system and method for controlling a digital video recorder on a cable network. Signaling associated with the answering or initiation of a digital telephone call by a digital telephone subscriber is used to issue commands to a digital video recorder (DVR). A signal is generated by an MTA when the telephone is enters an 'off-hook' state and sent to the DVR to initiate recording of a program being viewed by the called party. When the phone goes 'on-hook', the called party resumes watching the program from exactly where it was interrupted. The MTA may be connected directly to the VTD/DVR and the telephone state is determined by the DVR from information provided by the MTA. Alternatively, a soft switch monitors signaling from the MTA indicative of the state of the called telephone. A telephone state message comprising the telephone state information is then sent over an out-of-band channel/path to a DVR client within the VTD. The DVR client uses the telephone state information to control a DVR.

A system and method for providing a hybrid fiber network (HFN) means to identify a fiber node by a unique address. An addressing module is installed in proximity to, or collocated with, a fiber node. The addressing module comprises an addressing module identifier that associates the addressing module with a particular fiber node. Network parameter values are received from the fiber node by the addressing module and reported to a reporting station.

The detection of devices with duplicate media access controller (MAC) addresses in a cable network. A cable network device (CND) having a MAC address is connected by the cable network to a cable modem termination system (CMTS) having a gateway interface address. A centralized storage of historical cable modem MAC address/giaddr tuple data is used to identify CNDs that report duplicate MAC addresses. The cable network tracks the CND MAC address/giaddr tuple data of all CND requests that it receives and stores the MAC address/giaddr tuple data into a datastore (such as a database). When a CND seeks to access the network, the cable network looks into the datastore to determine whether the CND MAC address of the CND has previously been stored with a different associated giaddr, which would imply that there are multiple CNDs attached to different CMTSs where the CNDs share the same MAC address. If such duplication is detected, an appropriate remedial response is taken.
