A satellite modem for broadband communication. The satellite modem receives a satellite signal on a single carrier from a satellite. The satellite signal is divided by time division multiplexing into physical sub-channels encapsulating logical downstreams. The satellite modem includes a filter which removes a subset of the physical sub-channels intended for the subscriber terminal. The satellite modem includes a demodulator, a decoder, and a medium access channel. The MAC processes the logical downstreams.
