Methods and apparatus to detect wideband interference in digital subscriber line (DSL) systems are disclosed. An example method comprises retrieving a first plurality of performance parameters for a first time interval for respective ones of a plurality of DSL modems, wherein each of the plurality of DSL modems are associated with respective ones of a plurality of subscriber loops, and comparing each of the performance parameters to a threshold to determine whether two or more of the respective ones of the plurality of subscriber loops experienced respective performance degradations during the first time interval. The example method further comprises determining whether the two or more subscriber loops that experienced the respective performance degradations during the first time interval are communicatively coupled to a common serving terminal, and automatically generating a repair ticket when the two or more subscriber loops that experienced the respective performance degradations during the first time interval are served from the common serving terminal, the repair ticket representing a possible wideband noise interference condition affecting more than one of the plurality of subscriber loops.
摘要:
System(s) and method(s) that facilitate dynamic remote management of consumer premise devices comprising femtocells integrated into broadband gateways are presented. A communication network platform is associated with a consumer premise device(s) and can include a remote management component that facilitates dynamic and remote management of consumer premise devices in a wireless communication network. The remote management component monitors and measures desired parameters respectively associated with a consumer premise devices and employs remote controls to remotely adjust parameters based on predetermined optimization criteria. The remote management component calculates channel capacity based on measured channel signal-to-noise ratio to facilitate determining whether to hand off a current cell to another cell, wherein at least one cell is associated with a consumer premise device. The remote management component can generate and store Quality of Service profiles respectively associated with the consumer premise devices to facilitate remote management of the consumer premise devices.
