Figure 13: Redundant Ring Structure with ESMs
Notes
•The reconfiguration time of less than 0.3 s can only be achieved when no components other than OSMs and ESMs (for example switches) are used in the redundant ring.
•In a ring, one device and one device only must operate in the redundancy manager mode.
•DTEs or complete network segments can be connected to ports 1 – 6 (OSM/ESM with 8 ports) or ports 1 and 2 (OSM/ESM with 4 ports) of an OSM/ESM operating in the RM mode.
