1. A method operating a modem termination system (MTS) in operable communication with a plurality of modems over a duplex communication link configured to bi-directionally transmit a communication spectrum, the method comprising the steps of:
assigning a first portion of the communication spectrum as an upstream spectral portion, and a second portion of the communication spectrum as a downstream spectral portion;
transmitting, over the duplex communication link within the downstream spectral portion, downstream data to the plurality of modems;
receiving, over the duplex communication link within the upstream spectral portion, upstream data from the plurality of modems; and
controlling at least one modem of the plurality of modems to be switchable between a full duplex mode and a half duplex mode,
wherein, in the full duplex mode, the upstream spectral portion is the same as the downstream spectral portion, and
wherein, in the half duplex mode, the upstream spectral portion is different from the downstream spectral portion.
