Introduction
Welcome to Multi-Tech's new DSU ProxyServer, model
number MTPSR2-201, a single, secure gateway that provides
multiple LAN users with high performance Internet access
over a leased line. The DSU ProxyServer functions as a TCP/
IP proxy server that resides on the outer edge of your firewall
and provides up to 56K of bandwidth to LAN users. The DSU
ProxyServer features a 10BaseT port for local LAN
connection, a command port for configuration, a 56K bps DDS
4-wire WAN connection, and a RS232 port for auto-dial
backup in case the leased line connection is lost. System
management is provided through the command port using
bundled Windows® software which provides easy-to-use
configuration menus.
The MTPSR2-201 also supports dial-in Remote Access Server
(RAS) when the WAN 2 port is configured to support it. Refer
to the Software Installation section of this guide, and to your
ProxyServer User Guide for more details on RAS.

Cabling Procedure
Step Procedure
1. Connect one end of the power supply to a liveAC outlet
and connect the other end to the ProxyServer as shown in
Figure 3. The power connector is a 6-pin circular DIN
connector.
2. Connect the ProxyServer to a PC by using the short RJ45
to DB25 (female) cable provided with your unit. Plug the
RJ45 end of the cable into the Command port of the
ProxyServer and the other end into the RS232 cable from
the PC serial port. See Figure 3.
3. Connect a network cable to the ETHERNET 10BASET
connector on the back of the ProxyServer. Connect the
other end of the cable to your network.
4. Connect one end of the RJ48 cable to the 56K DSU
connector on the back of the ProxyServer. Connect the
other end to your DDS WAN connection.
5. If you wish to use the optional RS232 port for dial back-up,
connect one end of an RS232 cable to the RS232/V.35
connector on the back of the ProxyServer and connect the
other end of the cable to an external DCE device such as
a modem or T1 CSU.
5. Turn on power to the ProxyServer by placing the ON/OFF
switch on the back panel to the ON position. Wait for the
FAIL LED on the ProxyServer to go OFF before
proceeding. This may take a couple of minutes to go OFF.
At this time your ProxyServer is completely cabled. Proceed
to the next section to load the ProxyServer software.
