Multiple-Ring Configuration

RADring supports multiple independent rings in the same hub. Separation of

rings is achieved by placement of Ring-In/Ring-Out modules or repeaters

between the rings, or by setting an access module to terminate the ring. The

number of separate rings is not limited and allows a mix of 4 Mbps or 16

Mbps rings. An example is shown in Figure 1-7, where 4 and 16 Mbps rings

are connected via bridges to a 16 Mbps backbone. The bridge can be

provided by an external local Token Ring bridge.
