B.3 TOKEN RING NETWORKS BRIDGED TOGETHER
Figure B-3 illustrates the bridging of two token ring networks
together using a token ring to token ring network bridge. Bridging
ring networks is necessary when: the networks are of different ring
speeds (one at 4 Mbit/sec and the other at 16 Mbit/sec), or when there
is a need for networks to be connected and one or both of the rings is
at maximum capacity. In Figure B-3, one network is running at
4 Mbit/sec and the other is running at 16 Mbit/sec. The 16 Mbit/sec
ring network with 130 stations is close to its maximum capacity of
136 stations. When the two networks are connected, the bridge is

B.4 MMAC WITH ETHERNET AND TOKEN RING
SIMULTANEOUSLY
Figure B-4 illustrates the simultaneous installation of an Ethernet
network with a token ring network in the same MMAC. To connect
the two networks together requires a token ring to Ethernet bridge.
Without this bridge, information cannot pass between the two net-
works. In this illustration the Ethernet and token ring networks are
