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.
