Abstract:
1. A system for distributing a timing signal, the system comprising: a timing generator operable to insert a phase of a timing signal and a command signal into a framed signal; a distribution module operable to receive the framed signal from the timing generator; a bus control module operable to receive the framed signal from the distribution module and to distribute the framed signal to a telecommunication system, the bus control module further being operable to receive a first plurality of signals from the telecommunication system and to select a first derived clock signal from the first plurality of signals; the distribution module being operable to receive the first derived clock signal from the bus control module and a second plurality of signals from the telecommunication system, and to select a second derived clock signal from the first derived clock signal and the second plurality of signals; and the timing generator being operable to receive the second derived clock signal from the distribution module and to select the second derived clock signal as the new timing signal.
