OVERVIEW
The MM701G is a versatile, high-speed
modem that extends your Ethernet LAN in a
back-to-back implementation or connects your
LAN to one or more service providers. It
employs G.shdsl technology for fixed-rate or
rate-adaptive, symmetric rates up to 2.3 Mbps
over single-pair wiring and allows for multiple
management options, including an easy to use Web-based interface. In addition, the MM701G
supports 32 simultaneous Bridge/Router or PPP sessions to the same or different service
providers over its G.shdsl WAN interface. For sizeable deployment, the MM701G provides the
ability to download pre-defined configuration files to the flash memory instead of manually
defining each and every value for all modems.
The MM701G also includes several useful protocols and services. If you require IP addresses
tobe serveddynamically on your LAN, use the built-in DHCP server. If you need toupdate your
modem software, use the built-in TFTP client. If you require private IP addresses and need to
translate them into public IP addresses, use the built-in NAT function. If you need to exchange
IP routing information with another device, configure and implement RIP. For a complete list
of features, see Appendix A.
Use this guide to install and configure your MM701G. Before installation, be sure to verify your
shipping package contents and system requirements as described in the sections listed below.

You can manage the MM701G using a Web browser, console port, or a telnet session.
All of the MM701G features and functionality are accessible through the Web interface. In
contrast, there are some features not supported through the console port. For example, you can
enable or disable spanning tree through the Web interface, but not through the console port or
telnet. The same principle applies for deleting a WAN session and selecting ATM VBR as a
quality of s ervice.
To prevent losing your configuration changes, be sure to save them as described in “Saving

Protocol Select the message format to be used between the MM701G and the service
provider. You can configure each session with any of the three protocols listed
below.
• Select RFC 1483-Bridge if the MM701G forwards packets based on MAC
addresses. You can enable Spanning Tree when you select Bridge sessions. See
“Set Spanning Tree” on page 19.
• Select RFC 1483-Router if the MM701G routes packets based on IP addresses.
• Select PPPoA if the MM701G establishes PPP sessions with the service provider.
If you select RFC 1483 Bridge or RFC 1483 Router protocol, you only need to set up
one session.
You can, however, configure a combination of RFC 1483 Router/Bridge and PPP
protocols for a multiple session configuration.
State Select Enable to activate this session. Select Disable to deactivate this session. You
can set the state for each session. You can also change the state for a session at any
time using this parameter.
IP Address Determine how an IP address is assigned to a session:
• If you selected PPPoA protocol, Dynamic is automatically selected. The service
provider automatically assigns an IP address to this session. The IP address
displays in the box.
• If you selected RFC 1483-Router protocol, you enter the IP address supplied by
the service provider in the box. Do not select Dynamic.
• If you selected RFC 1483-Bridge protocol, you do not enter an IP address and
you do not select Dynamic.
Subnet Mask Determine how the subnet mask is assigned to a session:
• If you selected PPPoA protocol, the service provider automatically assigns a
Subnet Mask. The Subnet Mask displays in the box.
• If you selected RFC 1483-Router protocol, you enter the Subnet Mask supplied
by the service provider in the box.
• If you selected RFC 1483-Bridge protocol, you do not enter a Subnet Mask.

You can manage the MM701G using a Web browser, console port, and telnet session.
In comparison, you can manage more of the modem’s functionality using a Web browser rather
than using the modem console port and telnet access. For example, you can enable or disable
spanning tree through the modem Web interface, but not through the console port or telnet. The
same applies for deleting a WAN session and selecting ATM’s VBR as a quality of service.
However, there are scenarios in which using the command-line interface is preferred over the
Web interface. For example, if you cannot connect to the modem through the DSL line and
10Base-T port, you can still manage the modem through the console port.
The following sections describe how to use the command-line interface:

IMPLEMENTING POINT-TO-POINT
LAN EXTENSION
With a pair of MM701Gs, you can connect remote LANs by placing them “back-to-back.” One
MM701G is set for Customer Premise Equipment (CPE) mode and the other MM701G is set
for Central Office (CO) mode. By bridging traffic between these two modems you essentially
create one extended LAN that allows the use of a single IP subnet.
Straight out of its shipping box, the CPE modem is already configured for implementing
point-to-point LAN extension. There are no changes necessary for this modem. Furthermore,
there are only two configuration changes necessary for the CO modem:
• setitupforCOmode
• change the LAN IP address
These changes are described in “Quick Installation” on page 66.
However, if you already have a custom configuration (not using factory defaults) o n your
modems, refer to “Configuring the CPE Modem” on page 68 to configure the CPE modem and
“Configuring the CO Modem” on page 72 to configure the CO modem.

POTS Plain Old Telephone Service.
PPP Point-to-Point Protocol exists between the hardware layer and the network-layer
interface protocols. It is a widely used protocol for establishing connections on the
Internet. PPP provides the set up and release of connections for each session.
PAP/CHAP provide the authentication for the PPP sessions.
proxy IP address The proxy IP address is the WAN IP address for one of the 32 sessions. The proxy
IP address is used to enter static NAT entries. See IP address.
PVC Permanent Virtual Circuit is a logical connection comprised of a predefined static
route across a packet-switched network that is always in place and always available.
QoS Quality of Service is the configured traffic parameters that are assigned to a virtual
circuit, which specifies how quickly and how accurately data is transferred from the
sender to the receiver.
RFC Request For Comment is a series of notes that contain surveys, measurements, ideas,
techniques, and observations, as well as proposed and accepted TCP/IP protocol
standards. RFCs are available on the Internet.

RIP Routing Information Protocol allows routers to update the routing tables
automatically (for example with information such as how many hops between
destinations). The version of RIP you select for the session must match the version
supported by the service provider. Versions RIP1 and RIP-1 compatible are used for
broadcast. Version RIP 2 is used for multicast.
SEF Severely Errored Frames is the incoming signal has at least four consecutive errored
framing patterns.
SES Severely Errored Seconds is the seconds during which more than 2,500 bipolar errors
are detected on the line.
session The time during which two computers maintain a communication connection. An
example is a connection configured between the MM550 Integrated Access Device
and the service provider.
SNMP Simple Network Management Protocol is a protocol that specifies how to send
information between a NMS and managed devices on a network. The managed
devices run a program called an agent. The agent interprets SNMP request and
responds to them. SNMP is used to set device configurations, read device
configurations or read the device status.
Spanning Tree A bridging protocol that detects and prevents loops from occurring in a system
containing multiple bridges.
subnet mask A type of IP address that allows a site to use a single IP address for multiple physical
networks.
TCP Transmission Control Protocol is a transport protocol used to map inbound traffic
(from a remote IP address) to an internal (LAN) IP address. Establishes connection
with remote user before data transmission.
TCP/IP Transmission Control Protocol/Internet Protocol is a protocol used for
communications between computers over networks and the internet.
TFTP Trivial File Transfer Protocol is a protocol used to download card images or other files
from an external TFTP server to the NVRAM of any installed cards, or to upload files
from an installed card to an external TFTP server.
trap receivers PCs configured to receive SNMP traps (messages).
traps Autonomous, interrupt-driven, SNMP messages sent from a managed node to a
network management station to indicate that an event has occurred.
UAS UnAvailable Seconds is the number of seconds during which the line is unavailable.
UBR Unspecified Bit Rate is an ATM traffic type used for LAN traffic. When network
congestion occurs, the data is stored in a buffer until it can be sent.
