Connections Device description
duplex mode. EDS500devices additionally use a proprietary extension of the SHDSL standard
and can reach data rates of up to 15.000 Mbps. Wires with a diameter of 0.8 mm give a range
of 13 km at 2.048 Mbps or 25 km at 192 kbps.

3 Functional earthing and cable shield
ADVICE
The SHDSL interface is designed as a 2 wire interface. For an effective overvoltage
protection it is mandatory to connect the functional earthing as well as the cable shield.
