3.2 Network structures
Devices of the EDS500 family allow you to realize a wide variation of network structures like
point-to-point connections, lines, rings, stars, branches and meshed networks. The following
small examples should give an overview of possible network variants.

Various transmission media: SHDSL via copper cable (Cu), optical transmission via optical
fibre (FO).
All user stations (central station, branches) are connected via Ethernet (Eth) to the
transmission line.
