The present invention provides a communication device, such as a modem, that is capable of detecting whether it is capable of operating in a mode that is compatible with one or more of the Spectrum Management Classes. The modem automatically selects a mode of operation that is compliant with one or more of the Spectrum Management Classes. The communication device also determines whether it is capable of operating in multiple modes that are compliant with multiple Spectrum Management Classes, and is capable of selecting the modes of operation that optimizes the performance of the communication device. Furthermore, the communication device is capable of determining when it is not capable of operating in a mode that is compliant with at least one of the Spectrum Management Classes and which prevents operation of itself upon determining that it is not capable of operating in a mode that is compliant with at least one of the Spectrum Management Classes.

Method and apparatus for automatic selection and operation of a subscriber line spectrum class technology

Indirect digital subscriber line (DSL) service generally involves connecting conversion equipment that converts between DSL service delivered to a customer premises and DSL service that connects back to a data network. Indirect DSL service may be delivered on the same loop to the customer premises that also carries a native 0-4 KHz POTS interface. For larger deployments, the conversion equipment may include inverse multiplexing to combine multiple links back to the data network to support DSL service. Furthermore, the conversion equipment may include functions to digitize the POTS service. Aggregating DSL data from multiple customers and/or digitizing POTS service that may be multiplexed with the DSL data allows for significant pair gain opportunities.
