Abstract
A downlink orderwire integrator ( ) and separator ( ) for use in a processing satellite ( ) and a user terminal ( ) in a satellite based communications system ( ) is provided having a formatter ( ), a cell switch ( ) and a cell sieve ( ). The formatter ( ) generates orderwire cells ( ) with each orderwire cell ( ) having a header ( ) and a body ( ). The cell switch ( ) receives the orderwire cells ( ) from the formatter ( ) and traffic cells ( ) from at least one uplink ( ) and arranges the orderwire cells ( ) and the traffic cells ( ) in at least one frame ( ) to transmit on at least one downlink ( ). The frame ( ) includes a fixed custom frame portion ( ) and a fixed traffic portion ( ) that contains both the traffic cells ( ) and the orderwire cells ( ). The cell sieve ( ) receives at least one frame ( ) from the at least one downlink ( ) and separates the traffic cells ( ) and the orderwire cells ( ) from the traffic portion ( ), such that the formatter ( ) and cell switch ( ) are positioned within the processing satellite ( ) and the cell sieve ( ) is positioned within the user terminal ( ).
