Abstract: Methods, systems, and computer readable media can be operable to detect possible fraudulent use of a customer premise equipment device. Information identifying a device connected to a customer premise equipment device can be retrieved and compared to historical information identifying one or more devices previously connected to the customer premise equipment device. The customer premise equipment device can be classified as a device suspected of fraudulent use when the current information identifying a device connected to the customer premise equipment device is different than the historical information identifying the one or more devices previously connected to the customer premise equipment device.

Abstract: CMTS software keeps track of the number of call requests accepted during a given monitoring period, this number being referred to as Count. As each call request is received, Count is compared to the current value stored in an overload state MIB (which can change multiple times during a monitoring period based on the actual overload state as reported by fault management). If Count exceeds the MIB value, the call request is denied. After the monitoring period ends, the Count of call requests accepted is reset to zero and the count value begins incrementing at the start of the next monitoring period as calls are accepted.

Abstract: A communications controller (132) transfers communication links from a first receiver (144) to a second receiver (146) when a system quality parameter exceeds a threshold. The first receiver (144) is used to perform idle carrier scanning by tuning to each idle carrier and executing a quality metric measuring procedure for the carrier or a channel on the carrier. The quality metrics are stored in memory (160) and the idle carriers are ranked according to their corresponding quality metrics. The communication controller (132) adds or replaces carriers based on their ranking. In this manner, communication channels may be more efficiently managed.
