In peer-to-peer ring networks it has been customary to provide a master timing station at one point in the ring to originate timing reference signals for the communications of all stations. A problem with such ring configurations is their dependency on the operativeness of the timing station. If the timing station fails, the ring becomes effectively incapacitated, and the stations on the ring may no longer be able to communicate with each other. In order to avoid this, it has been proposed to permit each station to time its transmissions independently (e.g., with reference to an internal quartz oscillator local clocking source), while developing reception clocking references from incoming data (data transferred from a preceding station on the ring).
