ProxyServer User Guide
6MTPSR1-202ST
Introduction
Welcome to Multi-Tech’s new ProxyServer 200-Series, model MTPSR1-202ST, a single, secure
gateway that provides multiple LAN users with high performance Internet access. The ProxyServer
functions as a TCP/IP proxy server that resides on the outer edge of your firewall and provides Basic
Rate ISDN Service using its internal 2B+D terminal adapter. The MTPSR1-202ST supports dial in
Remote Access Server (RAS), RAS Dial-Out Redirector, and can act as an asynchronous Gateway.
The MTPSR1-202ST ProxyServer features a 10Base-T port for local LAN connection, Command
Port for configuration, and an internal 2B+D ISDN terminal adapter for 64 Kbps per channel or 128
Kbps effective bandwidth when software BONDing (Bandwidth ON Demand) using ML-PPP is
employed. BONDing starts with 64K and when a certain threshold is reached, the second 64K
channel is brought up and bonded.
The MTPSR1-202ST supports client and site filtering, dial-in remote access from a PPP client,
includes NetworkAddress translation (NAT) allowing corporate web, FTP, and mail servers access
from the Internet, dials on-demand for link establishment as Internet services are requested, and
handles HTTP, FTP, POP3, DNS, NNTP, TFTP, IRC, SMTP, Gopher, Finger, rlogin, and Citrix
requests.
System management is provided through the command port using bundled Windows®software which
provides easy-to-use configuration menus.

Front Panel
The front panel of the ISDN ProxyServer contains three groups of LEDs that provide the status of the
Ethernet LAN connection, the ISDN WAN connection, and the general status of the ProxyServer (Fail
and Power).
The Ethernet LAN LEDs display the activity of the LAN if the ProxyServer is connected to the LAN,
transmitting or receiving packets, and if a collision is occurring. The ISDN LEDs, or WAN port LEDs,
display the status of the port and show if the link is ready to transmit or receive serial data, and if one
or both Bearer Channels are active. The general group of LEDs indicates whether the self test
passed or failed and if the power On/Off switch on the back of the ProxyServer is set to On.

Chapter 3 - Software Loading
and Configuration

ProxyServer User Guide
16 MTPSR1-202ST
Introduction
This chapter covers procedures for loading the ProxyServer software from a Windows PC (Win98/95
or WinNT) and configuring your ProxyServer. Configuration includes setting up the LAN and WAN
port IP addresses, setting up the ISDN configuration default parameters, then downloading the
default setup to the target ISDN ProxyServer.
Before You Start Loading your Software
Consider the following choices before you configure your ProxyServer and record your selections on
the following pages; then refer to them while loading your software.
Network Configuration
üNetwork Switch Type_________________________________________
Select the network switch type your ISDN service provider uses at its local central office. You can set
the ProxyServer to NET3 (EuroISDN), or 1TR6 (German), AT&T 5ESS, DMS-100, or NI-1. If you do
not know the switch type, you can get the information from your ISDN service provider.
üData TEI_____________________________________________________
The Data TEI (Terminal Endpoint Identifier) is assigned to the data channel. You can select “Auto TEI,”
a fixed TEI, number (from 0 to 63), or “Disabled.”ATEI is a number used by the central office switch to
uniquely identify each device that is connected to the network. When it uses dynamic TEI assignments
(Auto TEI), the central office switch assigns a TEI each time the ProxyServer connects to the network.
However, the ISDN service provider may assign a fixed TEI at subscription time, in which case you
must configure the ProxyServer with the fixed TEI number. You can also disable the channel, which
may be useful when multiple ProxyServers are attached to a network terminator bus.
üVoice TEI___________________________________________________
The Voice TEI is the TEI assigned to the voice channel. You have the same choices as for the Voice
TEI: “Auto TEI,” a fixed TEI number (from 0 to 63), or “Disabled.”
üData SPID__________________________________________________
The ProxyServer must be configured with the Service Profile Identifier (SPID). The data SPID is
assigned by the local phone company and is for the specific Basic Rate Interface (BRI) line to which
the ProxyServer will be attached. The data SPID string can have up to 20 characters. The data
SPID is not used if the switch type is set to NET3.
Note: For DMS-100 switches, any ASCII character except the underline (_) character is valid. For
NI-1 and AT&T switches, only the digits 0-9 are valid.
üVoice SPID__________________________________________________
The voice SPID is assigned by the local phone company and is for the specific BRI line to which the
ProxyServer will be attached. The voice SPID string can have up to 20 characters. The data SPID is
not used if the switch type is set to NET3.
Note: For DMS-100 switches, any ASCII character except the underline (_) character is valid. For
NI-1 and AT&T switches, only the digits 0-9 are valid.
üData Directory Number________________________________________
The data Directory Number (DN) is a telephone number that is assigned to the ProxyServer at
subscription time by the ISDN service provider. The DN is a string of up to 24 characters; valid
characters are 0-9, the * character, and the # character.
üVoice Directory Number_______________________________________
The voice Directory Number (DN) is a telephone number that is assigned to the ProxyServer at
subscription time by the ISDN service provider. The DN is a string of up to 24 characters; valid
characters are 0-9, the * character, and the # character.

Chapter 3 - Software Loading and Configuration
17
MTPSR1-202ST
Call Control Parameters
üPersistent DTR Dialing_______________________________________
Ahigh DTR (Data Terminal Ready) signal on the Command port indicates that your computer or
terminal is ready to communicate with your ProxyServer. DTR normally goes high when a
communication program starts or is ready to dial. Persistent DTR dialing enables the ProxyServer to
automatically redial the number stored in memory location 0 whenever DTR is high and the serial port
does not have an active call. You may enable or disable this feature.
üCalling Line Identification_____________________________________
Identifies whether the two endpoints of a connection are enabled or disabled. Since RING messages
only appear for ISDN data calls, the CLI feature does not define a means of conveying Calling Party
information to the terminal for ISDN voice calls. The CLI information is only included with the first
RING message for a given incoming call and appears as follows:
RING
FM: 5552000 TO: 5551000
If the Calling Party Number information is not included in the incoming SETUP message, the RING
message appears as follows:
RING
TO: 5551000
If the Called Party Number information is not included in the incoming SETUP message, the RING
message will appear as follows:
RING
FM: 5552000
If neither the Called Party Number, nor the Calling Party Number is included in the incoming SETUP
message, the RING message will contain no additional information.
üAuto Protocol Detection - Always Unchecked (Disabled)
Identifies that automatic protocol detection is enabled or disabled for an ISDN data call. The default
setting is 0, which disables theAuto-Protocol Detection function.
üAuto Answer Data Calls ____ __________ Rings to Answer__________
Select Auto Answer if you want your ProxyServer to automatically answer all incoming data calls (this
option does not affect the analog port). The Rings to Answer number, in the range of 1 to 255, selects
the number of rings the ProxyServer waits before answering an incoming call. The default is one ring.
Data Control
üData Protocol _______________________________________________
The data protocol, also known as the B-channel protocol and the rate adaption protocol, is the
“language” that is spoken over each 64 Kbps channel between two ISDN devices. The devices on
both ends of the ISDN link must use identical data protocols.
MLPPP Protocol (Not supported on the MTPSR1-202ST)
The MLPPP (Multi-Link PPP) protocol provides rates up to 64 Kbps per channel. This protocol uses
both B channels at once, providing an aggregate data transmission speed of 128 Kbps.
üDialing Method _______________________________________________
Select either the “Enbloc” or the “Overlap” dialing method for use when establishing a data call. Your
ISDN service provider determines the dialing method. The en bloc method is used for most ISDN
dialing; however, you can select the overlap method if you are working with a private network.
