Various aspects of apparatuses and methods for enabling a subscriber premise network interface device (NID) to facilitate communication services including digitally derived voice services to be facilitated between a central office and a subscriber premise are disclosed herein. In accordance with one embodiment of the disclosures herein, such a method includes facilitating a downstream DSL voice channel transmission process at a subscriber premise Network Interface Device (NID) and facilitating an upstream DSL voice channel transmission process at the subscriber premise NID. The downstream DSL voice channel transmission process facilitates converting a voice component of a downstream DSL data stream to a corresponding downstream analog voice signal. The upstream DSL voice channel transmission process facilitates converting an upstream analog voice signal to an upstream voice component of an upstream DSL data stream.
