ABSTRACT:
A method, device and/or system for connecting at least one subscriber device, e.g., a legacy subscriber device, to a wideband distribution network. The device may include, for example, an up-converter to up-convert a subscriber upstream signal within a subscriber upstream frequency band supported by the subscriber device, into an up-converted upstream signal within an upstream sub-band of an extended upstream frequency band; and/or a down-converter to down-convert an extended downstream signal in an extended downstream frequency band, into a down-converted subscriber downstream signal within a subscriber downstream frequency band supported by the subscriber device.
