Connecting 10Base-T Ethernet Port to PC (DTE)
The 10Base-T interface is configured as DTE (Data Terminal
Equipment). If the
Compact mDSL Modem is to connect to another
DTE device such as a 10Base-T network interface card, construct a
10Base-T crossover cable and connect the wires as shown in the dia-
gram below.

Connecting 10Base-T Ethernet Port to Hub (DCE)
The 10Base-T interface is configured as DTE (Data Terminal
Equipment), just like a 10Base-T network interface card in a PC.
Therefore, it “expects” to connect to a 10Base-T Hub using a straight-
through RJ-45 cable. Use the diagram below to construct a cable to
connect the 10 BaseT interface to a 10Base-T Hub.

Compact mDSL Modem
Power Connection
Universal AC Power (100-240VAC)
The Compact mDSL Modem uses a 5VDC, 2A universal input
100-240VAC, power supply (center pin is +5V). The universal input
power supply has a male IEC-320 power entry connector. This power
supply connects to the Compact mDSL Modem by means of a barrel
jack on the rear panel. Many international power cords are available
for the universal power supply.
The Compact mDSL Modem powers up as soon as it is plugged
into an AC outlet. The Compact mDSL Modem does not have a power
switch.
120 VAC Power (US)
The 100-132 VAC adapter supplied with the U.S. version of the
Compact mDSL Modem is a wall mount type and may be plugged into
any approved 120 VAC wall jack.
230 VAC Power (International)
The 230 VAC adapter supplied with the International version of the
Compact mDSL Modem is a wall mount type and may be plugged into
any approved 230 VAC wall jack.
DC Power
The 36-60 VDC DC to DC adapter supplied with the DC version of
the Compact mDSL Modem plugs in a DC source (nominal 48VDC)
and plugs into the barrel power supply jack on the rear of the
MDU9705A-10BT. Please refer to Figure 8, below, to make the proper
connection.
