1. For use in an adaptive link power control (ALPC) satellite communications network wherein signals conveyed over a communications channel between transmitting and receiving terminals are amplified and relayed by a satellite amplifier device the power availability of which is controlled to meet the demands of the links of the channel, a method of preventing said satellite amplifier device from being driven to a signal amplification degradation state by adaptive link power control, in response to the attenuation of a signal relayed by said satellite amplifier device between said transmitting and receiving terminals, comprising the steps of:

  • (a) monitoring a signal representative of the signal amplification state of said satellite amplifier device; and

    (b) in response to the signal monitored in step (a) having a characteristic indicative of the onset of aaid signal amplification degradation state, selectively adjusting a prescribed characteristic of signals conveyed from said transmitting links to said satellite amplifier device.
