ABSTRACT:
Satellite communication system for speech signals located within the telephony band and one or more data signals, wherein half-duplex data traffic between ground-based stations can be effected simultaneously with, but separated from, full-duplex speech traffic between two ground-based stations. The use of a second receiver enables all ground-based stations to follow both the data traffic and the speech traffic.
