Dual-Homed Connection
This configuration:
avoids the need for an optical bypass switch (page 1-19)
provides redundancy so that failure of one cable or concentrator will
not break the router’s connection to the dual ring
During normal operation in the above example, traffic is sent and re-
ceived over port ‘‘B’’ of the router. Port ‘‘A’’ is used only if the cable or
concentrator attached to port ‘‘B’’ fails.
1. Attach port ‘‘A’’ of the to an ‘‘M’’ port of a concentrator.
2. Attach port ‘‘B’’ of the router to an ‘‘M’’ port of another router.
