Dynamic cable operator plant discovery

The present disclosure describes a point-to-multipoint communication system having a service provider system and one or more subscriber devices. The one or more subscriber devices include multiple physical layer (PHY) devices that can be used for upstream direction and/or downstream direction transfer of information to and/or from the service provider system. The one or more subscriber devices receive subscriber device configuration information from the service provider system indicating which of these multiple PHY devices are to be used for the upstream direction and/or the downstream direction transfer of the information to and/or from the service provider system. In some situations, the subscriber device configuration information identifies various types of information, such as video, audio, and/or data to provide some examples, to be transferred in the upstream direction and/or the downstream direction and/or one or more PHY devices to be used for transferring the various types of information.
