Abstract
A method and apparatus for expanding multiple token rings by interconnecting multiple multi-ring hubs. The computer networking hubs of the present invention are operable to support multiple token ring networks. In addition, the networking hubs of the present invention include a cable interface configured to interconnect the multiple token ring networks to a single cable interconnected with a separate hub, which is also configured to support multiple token rings. As a result, multiple token rings are able to be expanded across multiple networking hubs. In one embodiment, the networking hubs of the present invention are further operable to receive signals from remote nodes via a first signal mode. The signals are converted to a second signal mode to be transmitted internally. To transmit the signals to a separate hub, the signals are re-converted to the first signal mode and transmitted to a separate networking hub via the first signal mode. Transmitting between the separate hubs via the first signal mode helps to preserve the signal integrity and decrease the cross-talk between the wires of the cable interconnecting the hubs.
