(RSR20, RSR30, MACH1000)
The Sub-Ring concept enables you to easily couple new network segments
to suitable devices in existing redundancy rings (basis ring). The devices of
the basis ring to which the new Sub-Ring is being coupled are known as Sub-
Ring Managers (SRM).
Figure 15: Example of a Sub-Ring structure
1 Blue ring = basis ring
2 Orange ring = Sub-Ring
SRM = Sub-Ring Manager
