Abstract: A method for communicating between an airborne mobile terminal and a terrestrial location via satellite, whereby a number of encode/decode modules are eliminated from the communications path, thereby reducing the transmission delay and improving the quality of the transmitted voice data.

Abstract: In a facsimile system, buffer underflow is prevented by forcing the transmit pointer to wait at a current end-of-line (EOL) symbol and transmit fill bits until there are at least two EOL symbols stored in the buffer. Buffer overflow is controlled by selectively dropping lines if the write pointer approaches too close to the transmit pointer and the difference between successive lines is sufficiently small (selective line-dropping), dropping lines whenever a permitted maximum buffer size is exceeded, and gradually changing the permitted distance between transmit and write pointers and permitted maximum buffer size as the image is scanned to accomplish a smooth buffer flushing.
