ABSTRACT:
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.
