Abstract
An improved local area network node of the type described in ANSI/IEEE Standard 802.5, including a receiver-demodulator having an input connectable to the ring and having a received data output and a received clock output, an elasticity buffer connected to the received data output, a modulator for modulating the output of the buffer in accordance with a signal at a clocking input of the modulator, and a phase-locked loop interposed between the received clock output of the demodulator and the clocking input of the modulator, the loop including a voltage-controlled oscillator, a phase detector and a filter connected for providing a control-voltage to the oscillator.
