Introduction and Description
Welcome to Multi-Tech’s new MultiAccess Communications Server, Model MA30120. The MultiAccess
Communications Server is a high-performance digital remote access solution for Enterprise LANs and intranets or
internet service providers. MultiAccess is a V.92 remote access server (RAS) supporting up to four T1 line
interfaces implementing either RBS or PRI signaling for use in North America or up to four E1 line interfaces
implementing PRI signaling for international use. The MultiAccess Communications Server uses a web based
Graphical User Interface (GUI) for configuration, is a 1U (one-up) rackmountable unit that contains up to four
universal modem ports for dial-in communications.
WAN Communications
MultiAccess ships turnkey for T1/RBS or T1/E1 PRI ISDN and is populated with 30 modems on line interface 1 for
the basic configuration. Additional modem modules can be added to support up to four T1/E1 line interfaces.
The high-density modems provide V.92/56K dial-up speeds. In addition, they are manageable from remote
locations using platform-independent, industry standard protocols.
Management
MultiAccess includes robust management support allowing a network administrator to securely manage the
devices either through a web browser or at the command line. The browser-based option uses the HTTPS
protocol, also know as SSL (Secure Sockets Layer) to provide 128-bit encryption to secure the management
session. The command line interface is accessible via SSH (Secure Shell) and supports SCP (Secure Copy) and
sftp (Secure File Transfer Protocol) to help provide maintenance support.
SNTP Support. MultiAccess includes an industry standard Simple Network Time Protocol (SNTP) client that
enables it to synchronize its clock with a remote time/clock server on the Internet. This feature is useful for
accounting purposes.
Remote Access
Comprehensive Security. MultiAccess provides an industry standard Radius Server and Radius Client for
authentication and authorization of thousands of user profiles using PAP and CHAP. In addition, it uses Network
Address Translation (NAT) to hide internal, non-routable IP addresses. If a Radius Server does not exist, one is
provided as part of the MultiAccess system. This Radius Server could provide authentication and authorization
information for this and other Radius Clients in use at your site.
About This Manual
This Quick Start Guide is intended to provide the experienced system administrator the information needed to
quickly get the MultiAccess up and running. A User Guide with more detailed information is provided on the
MultiAccess system CD in Acrobat (pdf) format.

• Determine physical access point to the Ethernet network.
• Identify high quality category 5 cable for Ethernet & T1 cabling. Depending on environment characteristics,
shielded T1 cable may be necessary.
• For initial setup and administrative purposes, a network workstation with a WEB browser supporting HTTPS will
be needed.
2. Define your users’ client computer needs
• Determine the number of dial in analog modem users
• Identify client workstation OS (PC running Windows®98/XP/2000, or MAC OS10)
• Identify client modem types (V.34, V.90, V.92)
• Identify dial up security protocol (CHAP & PAP)
• Third-Party Security Devices (SecurID)
• Identify the Security Database (i.e. user file in RADIUS server or Microsoft SAM\Active directory with IAS) and
make sure users have dial in rights with framed protocol PPP attribute
3. Identify applicable network resources (IP address of; gateway/default route, DNS, WINS, RADIUS server(s), etc)
• Identify the network MASK
• Identify available IP addresses (determine the static IP address that is to be assigned to the Multi Access)
• Determine IP assignment method (predefined pool/range) to be implemented by the MultiAccess (regarding the
IP addresses to be assigned to the remote dial in users).
• When Implementing RADIUS Authentication and Accounting, identify the UDP ports used by the RADIUS
server(s)
4. Define your line interfaces
• Obtain T1 or E1 PRI line provisioning information for your LEC
• Identify the telephone number(s) of the line or lines
• Identify the Framing Format
• Identify the Line Coding

Hardware Installation
The MultiAccess is designed to install either on a desktop or in a standard EIA 19“ rack, and is shipped with the
mounting hardware to install the MultiAccess in the rack. If installing in a rack, use the provided mounting hardware
and follow the rack enclosure manufacturer’s instructions to safely and securely mount the MultiAccess in the rack
enclosure. Proceed to the cabling procedure.
Cabling Procedure - Back Panel
Cabling your MultiAccess involves making the proper power, phone, and line (T1/E1/PRI) connections as described
and illustrated below.
The MultiAccess back panel has a fan, a power plug, POWER Switch (| / O), a RJ-11 phone LINE jack, a DB-9 COM1
jack, a DB-15 High-density DSUB (VIDEO) jack, two USB (Revision 1.1 compliant) jacks, four RJ-45 T1/E1/PRI line
jacks, and two Ethernet RJ-45 (Ethernet 1 & Ehternet 2) jacks.
1. Using an RJ-45 cable, connect one end to LI-1 (Line 1 Interface) on the back of the MultiAccess and the other
end to your first T1/E1/PRI line connection. If a second, third, or fourth line connection is required, connect an RJ-
45 cable for each of the line connections being used.
2. Connect a workstation to your local network, connect one end of an RJ-45 cable to the Ehternet 1 jack on the
back of the MultiAccess and the other end to the hub on your local network.
3. For advanced users, the Video and Keyboard connections are for manual intervention of the Operating System.
The default root level login password is linux (lower case) and the command to change the root level password is
“passwd”. The recommended mimumum password length is 8-characters. However, the MultiAccess will accept
less than 8-characters.
The Linux command to properly shut down the MultiAccess is shutdown -h now. The command to restart is
shutdown -r now.
4. With the MultiAccess Power switch in the off (Ο) position and using the supplied power cord, connect the
MultiAccess power plug to a live power outlet.
5. Place the MultiAccess Power switch to the on (|) position to turn on the MultiAccess
Caution: Never switch off MultiAccess Power until after you have performed the Shutdown
process. Refer to Administration > System Tools in Chapter 3 of the User Guide. If the MultiAccess is not properly
shut down before switching off Power, the next start may take a little longer, or in the worst case, data could be lost.
6. Proceed to Starting the MultiAccess.

Starting Your MultiAccess
This section of the Quick Start Guide covers the steps for connecting a workstation to the MultiAccess, starting up
the MultiAccess, opening the MultiAccess Communications Server Web Management program, performing the
time zone setup, and using the menu bar to navigate through the Web Management software screens.
1. Set the workstation IP address to 192.168.2.x subnet other than 192.168.2.1 which is the IP address of
Ethernet 1 (eth0) and 192.168.2.5 which is already assigned to Ethernet 2 (eht1).
2. Turn on power to the MultiAccess. When you hear 5 beeps, approximately 2 minutes after applying
power, continue with the next step.
Note: Depending on the version of MultiAccess (and other variables, like the previous shutdown and the
number of expansion modules) the duration needed to boot may vary. It may be helpful to connect an
external monitor and keyboard to determine the current status of the system. Five seconds after turning
on power, one beep is heard, indicating a successful POST of the mother board, next the BIOS detects
the hard drive from which the Linux operating system and appropriate drivers are loaded.
3. Bring up a Web browser on the workstation. At the browser’s address line, enter https://192.168.2.1 and
press the Enter key.
Important: Be sure to type https (http will not work).
4. In some environments, one or more Security Alert screen(s) may display. At the initial Security Alert
screen, click Yes and follow any additional on-screen prompts.
Login
1. The Login screen is displayed.
•Type the default User name: admin (all lower-case)
•Tab to the Password entry and type the default password: admin (all lower-case).

Modem Setup
The Modem Setup group of menus configure the modems for usage with RAS, modem sharing, and faxing. The
default usage for each modem is RAS. The Modem Setup menu controls the parameters of the modems set to
RAS. If the MultiAccess modems are to be used for dialout, in a networking modem sharing environment, then
use the Modem Usage menu to change the usage to Modem Sharing. If the MultiAccess modems are to be used
for faxing with the integrated Hylafax™Server, then use the Modem Usage menu to change the usage to Fax.
The Fax Setup menu is used to configure the Hylafax Server for sending and receiving faxes.
Note: The MultiAccess modems also support faxing with fax servers that are external to the MultiAccess via the
Modem Sharing usage.
Modem Usage
If you are using all your MultiAccess modems to provide dial-in PPP access, you do not have to modify the default
Modem Usage settings. The default usage is RAS. If you plan to use all or part of your MultiAccess modems for
dial-out, you will have to change the Modem usage settings for the selected modems to one of the Modem
Sharing options that best fit your needs. If you plan to use some or all your modems for faxing, you will have to
change the Modem Usage setting for the selected modems to Fax.
1. If you are using your MultiAccess in an RAS inbound PPP environment, you do not have to make any
changes in the Modem Usage menu.
Note: When implementing a combination of usage options, care must be given so that inbound calls do not
conflict with outbound calls. This may require changing the hunt group call distribution at the central office and
should be addressed with the provider of your T1/E1 digital line.
Caution: Modem sharing is accomplished by implementing a Telnet interface to the MultiAccess modems. Make
sure that care is taken to secure access to these ports via firewall or IP filter settings to prevent unauthorized use
of your modem resources.

MultiAccess Quick Start Guide Connecting & Starting the MultiAccess
Multi-Tech Systems, Inc. PN 82001423L 13
If you are using your MultiAccess as a network modem pool, you will need to set up the Modem Usage menu to
support your configuration.
1. Click on the Usage drop down arrow and chose the Modem Sharing – authentication type that suits your
applicational needs.
2. Click on the Modem drop up or down arrow and select the tty modem(s) for modem sharing. You can choose
multiple modems by holding down the shift key.
3. When the Modem Usage is set to Modem Sharing, the following options become available:
Display Called Number - This parameter applies to inbound (received) calls when the Line Interface type is
PRI. The telephone number (or final digits) dialed by the originator will be displayed into the telnet socket
following the first “ring” message. The Called Number information (string of digits) is provided by the central
office switch and is commonly referred to as DNIS. The MA30120 does not support DNIS when the Line
Interface type is T1-RBS.
Reverse Dial - This parameter enables two features, comma dialing and reverse dial mode. When enabled,
the dial string can include the use of commas, used to create a pause between digits of the dial string (most
commonly used to specify the extension of the answering modem).
Example: “atdt18003334444,,,,,4321”. Each comma creates a 2 second pause. 4321 is the extension of the
desitination phone line\modem.
Reverse dial mode is where the dial string includes the letter “r” at the very end of the dial string, the purpose
of which is to instruct the MA30120 modem to switch from originate to answer mode after dialing. For
example: “atdt17637175549r”.
Please Note: When Reverse Dial is enabled, the dial string must include the tone (t) command, for example,
atdtstring .

Connecting & Starting the MultiAccess MultiAccess Quick Start Guide
14 Multi-Tech Systems, Inc. PN 82001423L
Raw Mode - If Yes, this sets the TCP port to a RAW socket. User data is treated “as is” and the Telnet
Command Escape capability is disabled. If No, this allows the Telnet command parser to look for escape
sequences that are used to communicate control functions. A common example is to support RFC-2217 Com
Port Control.
Pool -If you want to access a specific modem, accept the default of No. Each modem will be given a specific
TCP port number, starting at 7000+. If you select pool = Yes, then all selected modems are accessed via port
number 6000 – creating a first available pool, starting with the lowest numbered tty port.
SSL -Support is made available when the usage is Modem Sharing with Authentication. This is only used
with SSL capable Telnet Clients. Site Certificate information needs to be configured appropriately. Contact
Multi-Tech Tech Support for additional information.
Idle Timer (seconds) - The Idle Timer, upon expiring, will hangup the modem and close the telnet socket.
Idle time is defined as no data flow in both directions. Any data sent or received across the socket will cause
the Idle Timer to start over. When there has been no data activity for the duration specified, the idle timer will
expire.
Monitor CD -Upon the modem disconnecting, the MultiAccess will close the telnet socket to the host
application server.
4. Click on the Save button.
If you are using your MultiAccess as a network fax server, you need to set up the Modem Usage menu to support
your configuration.
1. Click on the Usage drop down arrow and select Fax.
2. Click on the Modem up or down arrow and select the tty modem(s) for faxing. You can choose multiple
modems by holding down the shift key.
3. Click on the Save button.

defined in the Modem Usage Setup field of the Modem Usage screen.
1. Verify that the V.92 Setup parameters conform to your client’s characteristics.
2. Multi-Tech recommends that you set Retrain Limit to 4 and due to compatibility issues seen with various
modems, you may wish to disable Quick Connect and V.8bis.
3. If additonal modem commands are required, refer to Appendix B, Advanced Commands in the User Guide.

Fax Setup
Fax setup is initiated when you allocate modem(s) to the integrated Hylafax™Fax Server. This is achieved by
setting the selected modem’s usage to Fax. The Fax Setup screen is used to configure the integrated Hlyfax
Server for sending and receiving faxes.
The sending of outbound faxes via the Hylafax Server requires the use of a Hylafax compatible Fax Client
software, e.g., Multi-Tech’s FaxFinder Client. The General Fax Setup group is used to add Fax Clients to the
Hylafax server.
The Fax Client must be installed on each workstation that you wish to send faxes from. The Fax Client must use
the credentials defined in the General Fax Setup group to submit faxes for sending. The Fax Client is not used for
receiving faxes.
Inbound faxes received from the T1/E1 digital line are converted to tiff files and then emailed from the Hylafax
server to the specified recepient. The Fax Delivery Setup group is used to configure the routing of inbound faxes.

Outbound Fax Client Data Base
The outbound fax client data base is generated in the General Fax Setup group. The current outbound fax client
data base is shown in the table at the bottom of the General Fax Setup group. The credentials defined here are to
be used by the fax client. The fax client uses these credentials when accessing the Hylafax server.
1. To establish a fax client data base, enter each user name and password in their respective windows and
click the Add button for each entry.
Note: All fax clients can use the same set of credentials, or a unique set for each client can be added.
Fax Modem Settings
These settings are used to define the fax station identity and other administrative variables. The default settings
are normally sufficient with the exception of the “Rings Before Answer” parameter. When the Called Number
feature is used, the Rings Before Answer must be set to 2 for all the ports. Each Fax Modem is to be configured
with a unique Local Identifier, which is used as the TSI (Transmit Station Identifier) when sending faxes and is
included in the body of the email when receiving faxes. You can limit the maximum number of pages being
received.
Inbound Fax Data Base
The Fax Delivery Setup group is used to configure the routing of inbound faxes. The current fax routing table is
shown at the bottom of this group. Who the fax should be delivered to (routed to) is determined by one of two
routing methods:
A) “Route by Device” (what tty port the fax was received on),
B) Route by Called Number” (number dialed by the remote sender).
Route by Device is a static delivery method, where all faxes that are received on that particular port will be sent
to the email address defined for that port.
1. To deliver the fax based on the port (device) it was received on, select the radio button “Route by Device” and
then highlight the ttyMXxx port(s) from the corresponding window in the Fax Delivery Setup group,
2. Enter the email address of the fax recipient in the Email window and then click add.
Route by Called Number is a dynamic delivery method that requires the use of a PRI line (T1-PRI or E1-PRI line
type). Route entries are to match the DNIS information (provided by Telco per call) to an email address. The
Telco switch will (via PRI signaling) provide DNIS digits to the MultiAccess at the time of ringing (call setup). How
many digits will Telco be providing? The remote originator of the fax may dial 11 digits (1-800-333-4444) but
Telco may only provide the last x number of digits (where x is commonly = 4). DNIS digits provided by Telco is a
variable to be determined at the time of ordering and installing the PRI service. If no Called Number route entries
can be matched to the DNIS provided for that call - the default route entry will be used.
1. To deliver the fax based on the number dialed, select the radio button “Route by Called Number”.
2. Enter the email address of the fax recipient in the Email window.
3. Enter the DNIS string matching the number dialed and then click add.
The entry should be added to the route table found at the bottom of the screen.
