ABOUT THIS USER MANUAL
Use this manual to install, configure, and manage the ADC®Megabit Modem®MM701G and
MM702G. These modems can be used in two types of applications:
•as an endpoint (CPE) to a DSLAM for Internet and other broadband connection through a
service provider
•as a LAN extension by implementing a point-to-point connection with another modem of
the same model (MM701G to MM701G or MM702G to MM702G)
To complete an endpoint installation for an MM701G or MM702G modem, follow the
configuration instructions in all chapters of this manual, with the exception of Chapter 7,
“Implementing a Point-to-Point LAN Extension.”
To complete a point-to-point installation for two MM701G or two MM702G modems, follow
the configuration instructions in these chapters only:
•Chapter 1, “Installing the Modem”
•Chapter 2, “Accessing the Web Interface for Modem Management”
•Chapter 5, “Configuring System Parameters”
•Chapter 7, “Implementing a Point-to-Point LAN Extension”
•Chapter 8, “Configuring Modem Security”
After configuring the modem(s) for your application, monitor its status and perform other
management functions using the instructions in Chapter 9, “Managing the Modem.” If you
choose to manage the modem through the console port, use the instructions in Appendix A,
“Accessing the Command-Line Interface.”

INSTALLING THE MODEM
The MM701G and MM702G are versatile, high-speed modems that connect an Ethernet LAN
to one or more service providers using G.shdsl transmission technology. The connections
provide instant and high-speed broadband access to the Internet or to other types of Wide Area
Networks (WANs). The MM701G and MM702G provide:
•configuration either as a point-to-point LAN extension or as an end-connection to a
DSLAM (see page iii for the process you must follow to complete either installation)
•larger packet sizes to accommodate VLAN traffic
•32 simultaneous Bridge/Router or PPP sessions to the same or different service providers
over the WAN interface
•protocols and services such as DHCP server, DNS Relay, NAT, and RIP
•capability to download pre-defined configuration files to the modem flash memory instead
of manually defining each and every value for a modem
STEP 1—UNPACK THE MODEM
If you store the modem for a long period of time, use the original antistatic bag and packaging.
Observe environmental specifications provided in Appendix B.
1Remove the modem from the packaging.
2Visually inspect the container for signs of
damage. If the equipment was damaged in
transit, report the damage to the transportation
company and to the sales representative.
3Check the contents of the package for:
•6 Vdc power supply with cord
•black Cat. 5 cable for Ethernet connection
•silver cord for DSL connection
•flat cable (gray) and DB-9 port adapter for
console port connection

STEP 2—DETERMINE WHAT YOU NEED
In addition to what is shipped with the modem, you need the following hardware and software
to complete the installation and configuration.
STEP 3—ATTACH FEET TO THE MODEM
Attach oval rubber feet to the modem to prevent it from slipping on surfaces (a desktop, for
example) and from scratching those surfaces. Do the following:
1Remove the paper from the adhesive back of the oval rubber feet.
2Attach each of the four oval rubber adhesive-backed feet to a footprint recess on the bottom
of the modem.
Equipment: Requirement:
PC Hardware:
•Ethernet NIC Card (10 Mbps) installed in each PC and other network equipment
that will be connected to the LAN. Verify if the NIC in the device which directly
connects to the modem LAN port is half- or full-duplex. The modem LAN port
must be set to the same transmission direction(s) as the NIC.
•Optional—serial interface card installed in PC (used for access to the modem
console port).
Software:
•TCP/IP protocol stack installed (see the operating system documentation for
information).
•Terminal emulation program (such as HyperTerminal) installed for access to
the command line interface. through the console port (see the operating system
documentation for information).
•Web browser installed such as Internet Explorer®Version 4.0 (or higher).
•Operating System CD-ROM (Win98, Win98SE, Win2000, WinME, or WinXP).
Ethernet hub, switch,
or router
Optional—use either a hub, switch, or a router to connect multiple PCs or other
LAN equipment to the modem Ethernet 10Base-T port (LAN port).

of the following:
•MDI-X when connecting to a device
such as a PC Ethernet NIC card that
has an MDI port

hub, or router
•power cable to the modem power connector and to facility power
3Refer to “LED Status Indications” on page 5, to check modem LED status indications.
Ensure that the NIC in the PC and the modem LAN port are both set to either
half- or full-duplex for the transmission direction(s). If you need to change the
modem LAN port setting to match the NIC, follow the procedures in “Manage
DSL” on page 118 (half-duplex is the default).

ACCESSING THE WEB INTERFACE
FOR MODEM MANAGEMENT
Use the Web interface as the most comprehensive and convenient way to set up and manage the
modem. This chapter provides steps to help you access the Web interface pages for
configuration and management of the modem.
Access to the command-line interface is available through the modem console port or over
a network using a telnet session. Not all configuration and management features, however,
are supported through the command-line interface. See Appendix A, “Accessing the
Command-Line Interface” on page 99 for instruction on using the command-line interface for
configuration and management.
STEP 1—ASSIGN IP ADDRESSES
To access the modem Web interface, the management PC must be on the same LAN IP subnet
as the modem. Default values are shown to the right. Do one of the following:
•Change the management PC IP address so that it is on the
same subnet as the modem (go to page 8 and begin with
Step 1).
•Change the IP address of the modem 10Base-T (LAN) port
to a value assigned by your network administrator using the
command-line interface (go to “Set Up the LAN” on
page 104).
Modem Defaults
Subnet 10.0.0.0
Subnet Mask 255.255.255.0
IP Address 10.0.0.1

Assign IP Addresses
8MM701G and MM702G User Manual
Use the following steps to set up a management PC to be on the same subnet with the modem.
(The example shows instructions for a PC that is running Microsoft Windows 98 SE;
instructions for other operating systems may differ slightly.)
1From the Windows desktop, click Start, Settings, Control Panel to open the
Control Panel dialog.
2From the Control Panel dialog, double-click the Network icon (shown to the
right). The Network dialog is displayed.
3From the Configuration tab, double-click TCP/IP to display the TCP/IP Properties dialog.
4The modem can be set up to serve IP addresses to devices on the LAN (DHCP server
feature). Do one of the following:
•If DHCP server has not been enabled on the modem (default setting), select Specify an
IP address.
•If DHCP server has been enabled on the modem, select Obtain an IP address
automatically and go to Step 6.
5Enter an IP Address and Subnet Mask that places the management PC on the same subnet as
the modem. Use an IP address in the range of 10.0.0.2 to 10.0.0.254.
6Click OK to close the TCP/IP Properties dialog.
7Click OK to close the Network dialog.
8Click OK to restart the computer.
