Abstract: A method of providing a recovery channel for a common transmission network of remote devices comprising encoding data that contains information about a primary carrier signal, modulating the encoded information, spreading, the modulated encoded information such that a secondary carrier signal results, combining, the spread secondary carrier with the primary carrier signal such that the spread secondary carrier signal occupies at least a portion of a bandwidth of the bandwidth pool, transmitting the combined primary and secondary carrier signals across a communications link having a plurality of remote carrier signals also being transmitted across the communications link to a remote receiver and sharing a same bandwidth pool (or multiple bandwidth pools), and reestablishing the communications link with the primary carrier signal after a loss of the communications link using the information about the primary carrier signal contained in the secondary carrier signal to recover one or more network configuration parameters.

Abstract: A method of maintaining a data rate of a telecommunications link that involves, in a particular embodiment, modulating a carrier signal, encoding the carrier signal, and dynamically controlling a bandwidth of the carrier signal by changing a symbol rate of the carrier signal such that a data rate of the carrier signal remains substantially equal to a predetermined data rate when the carrier signal is transmitted to a remote receiver.

Abstract: A method for remotely and dynamically controlling adjacent satellite interference comprising monitoring one or more off-axis signals emitted by one or more remote transmitters; determining whether one or more of the off-axis signals is creating adjacent satellite interference (ASI), off axis emissions and inband interference that is higher than a predetermined level of acceptable interference, and transmitting a control signal to at least one of the one or more remote transmitters in response to the determination that the one or more off-axis signals is creating interference that is higher than the predetermined level of acceptable interference, the control signal initiating an adjustment to one or more transmission parameters of the one or more remote transmitters such that interference resulting from the one or more off-axis signals emitted by the one or more remote transmitters is reduced or eliminated.

Abstract: A method of hitless switching over a communications link, the method comprising transmitting, by a first modulator to a remote receiver, a first carrier signal having a first center frequency, enabling, by a second modulator to the remote receiver, transmission of a second carrier signal having a second center frequency while the first modulator is transmitting the first carrier signal, increasing, through the second modulator, a power level of the second carrier signal while the first carrier signal is transmitting, simultaneously decreasing, through the first modulator, a power level of the first carrier signal while the power level of the second carrier signal is increasing, and disabling transmission of the first carrier signal to the remote receiver when the power level of the second carrier signal reaches a predetermined level.
