branch
Station 1: coupling EDS500 devices with back-to-back-connection of Ethernet ports.
As an alternative to SHDSL via copper lines transmission can use optical fibres. Use the
corresponding EDS500 devices.
It is possible to establish a branch at any point in ring structures and other structures.

Figure 5: Example for network structure: Redundant
point-to-point connection
Connections between stations can be designed as redundant routes with an additional line.
For this you can use copper lines for SHDSL as well as optical fibres. The automatic selection
of the best available transmission line leads to better operating security. (see EDS500 Manual
