Operation
The compact modem 500NMD11 has one SHDSL wide
area interface, one optical interface as SFP plug-in
and four Ethernet interfaces. There are two serial
interfaces for configuration or process interface (e.g.
to connect telecontrol units). A configurable alarm
relais and an extension interface (e.g. to use the
configuration stick) complete the device.

Connections
Ethernet interfaces (Port1 - Port4)
Every Ethernet interface detects automatically
whether the connected counterpart works as
transmission or network termination device. This way
both normal and crossover cables can be used (MDI/
MDI-X).
The Ethernet interface can operate at transmission
rates of 10 or 100 Mbps, depending on the connected
devices in half duplex or full duplex mode. The
operation mode is detected and set automatically
by the EDS500 devices. A manual configuration is
possible.

Configuration
and Monitoring
Only transceivers up to laser class 1 according to
EN 60825-1 are allowed to be used for the SFP
interfaces.
Any warranty claims can only extend to SFPs
delivered by ABB.
DSL interface (X3)
The data transmission method SHDSL "Single-pair
High-speed Digital Subscriber Line" has been specified
by the International Telecommunications Union
(ITU recommendation G.991.2) and represents a
modern, high performance, comfortable and secure
communication method. SHDSL works with data rates
from 192 kbps up to 5.696 Mbps on a copper pair in
full 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.
