Abstract

Aspects of the subject disclosure may include, for example, a network termination includes a downstream channel modulator modulates downstream data into downstream channel signals to convey the downstream data via a guided electromagnetic wave that is bound to a transmission medium of a guided wave communication system. A host interface sends the downstream channel signals to the guided wave communication system and receives upstream channel signals corresponding to upstream frequency channels from the guided wave communication system. An upstream channel demodulator demodulates upstream channel signals into upstream data. Other embodiments are disclosed.
