Abstract
An apparatus for establishing timing signals of a communications network includes a plurality of ports and an internal trunk circuit for interconnecting trunk segments and lobes of the network. A speed detection circuit connected to each of said plurality of ports, are provided for sensing a plurality of timing signals, there being one timing signals sensed at each of the plurality of ports. The apparatus establishes a timing signal on the internal trunk equal to the timing signal senses at a majority of the ports to enable a majority of the nodes connected to a majority of the plurality of lobe ports to transport communications signals via the network.
