The Megabit Modem 400F uses ATM over DMT ADSL technology to provide this high-speed
transmission between the modem and the service provider. Asynchronous Transfer Mode
(ATM) provides transmission of fixed-size cells over preestablished connections for a network
interface that is predetermined and always in place. The Asymmetric Digital Subscriber Line
(ADSL) provides rate-adaptive transmission which means that the service provider can deliver
the best possible transmission rate to you based on distance and line conditions, in addition to
providing phone service to you over the same single-pair line.
The Megabit Modem 400F is easy to install and configure. To install the modem:
•
connect a telephone cable from the modem to a wall phone jack for ADSL service
•
connect a cable from the modem to a PC or an Ethernet hub for LAN service
•
connect a power cable to a local power source
To configure the modem, launch a Web browser on your PC and load the Megabit Modem
Configuration and Management Tool Web pages that guide you through configuration. Use
the Web page called EasySession™ to configure up to 32 simultaneous sessions with service
providers. You can also configure other system parameters and monitor ADSL, LAN, and other
networking functions using the Web pages.
LEDs on the modem front panel provide continual status at-a-glance for network and modem
connections.

SETTING UP THE PC TO REQUEST AN IP ADDRESS
The modem, as a Dynamic Host Configuration Protocol (DHCP) server, provides an IP address
dynamically to devices on the LAN. When you choose to use DHCP for the modem to serve
IP addresses to the devices on your LAN, ensure that the TCP/IP properties are set to
automatically obtain the IP address from the modem.
The following is an example of how to set up the PC using Microsoft® Windows® 95. If you
use an application other than Windows 95, refer to the appropriate operating system user
documentation.
1
Open the Control Panel window and double-click on the Network icon
shown at right.
2
In the Network dialog (shown below), double-click TCP/IP under the
Configuration tab (or highlight TCP/IP then click Properties).

Troubleshooting
TROUBLESHOOTING
If this occurs:
Try this:
PC or hub not
communicating
with the modem
• Check the LINK LED. If it is off, check the cabling to the 10/100BASE port and to the hub
or the NIC card in the PC to ensure it is secure.
• Check the position of the MDI/MDI-X switch. Set the switch to MDI when connecting to
a PC. Set the switch to MDI-X when connecting to a hub or router.
• Check that you are using a Web browser (Netscape or Internet Explorer) version 4.0
or newer.
• Check that you have a TCP/IP protocol stack installed on your PC.
• If this is the initial installation, check that you set the IP address on your PC to obtain an
IP address automatically. Make sure you have configured the LAN IP address of the
modem to an address that is on the correct subnet. See “Setting Up the PC To Configure
the Modem” on page 18.
• You configured the LAN IP address of the modem to an address that is not on the
same subnet.
• Check the NIC card installation for correct IRQ, drivers, and adapter setup. See
appropriate documentation for the NIC card.
SYNC ADSL LED
If none of the above corrects your problem, contact your service provider.
Contact the service provider when the LED remains off indicating that the modem is not
detecting a transceiver at the far end. Flashing green indicates that the modem is attempting
to bring up the link. Solid green indicates that the loop is up.
The modem synchronizes at a minimum transmission rate of 64Kbps. The modem rate
adapts in increments of 32Kbps.
MARGIN ADSL
LED lights green
Contact the service provider when the LED is off indicating that the margin is below that
specified by the service provider.
LAN TX and RX

TECHNICAL REFERENCE

This chapter provides technical information about how your modem transmits data between
users on your LAN and a service provider over the WAN.
ADSL
Asymmetric Digital Subscriber Line (ADSL) is the technology used to transmit data between
the modem and service provider at the physical layer. It provides data at asymmetric rates so
that downstream traffic from a service provider to you is faster than upstream traffic from you
to the service provider. The downstream transmission rate is up to 7.552 Mbps, while the
upstream rate is up to 928 kbps. Included in the ADSL bandwidth is analog POTS.
Discrete Multitone (DMT) is the line coding used for ADSL. Basically, it divides the
bandwidth into subchannels. Some of the subchannels are reserved for analog POTS. The
other subchannels are allocated to upstream and downstream traffic. Within the upstream
and downstream subchannels, some subchannels are used for management and
performance functions.
DMT ADSL provides rate-adaptive transmission that allows the service provider to deliver you
the best transmission rate determined by distance and line conditions.
ATM
Asynchronous Transfer Mode (ATM) is a technology that can simultaneously transmit voice,
data, and video over ADSL. ATM uses fixed-size cells that transmit over a preestablished
connection called a Permanent Virtual Circuit (PVC). Quality of Service provides UBR.
ATM cells are 53 bytes that comprise a 5-byte header and 48-byte payload. The header includes
the Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) that you entered when you
configured each session in Chapter 4. The VPI and VCI provide the virtual connection between
the modem and the service provider. The VPI identifies the Virtual Path (VP) that transports
Megabit Modem 400F User Manual
61
ATM
ATM cells in a Virtual Channel (VC). The Megabit Modem 400F has 32 VCs in the VP, which
provides the 32 sessions.
Mapping an ATM Session
Your service provider will give you a VCI and VPI address for each session. The VCI address
for each session (each session is a VC) can be a number from 32 up to a maximum of 255, with
the first 32 numbers (0 through 31) reserved. The VCI value for each VC must be unique for
each of the 32 sessions. The addresses range from 0 to 253 for VCI and 0 to 15 for VPI.
62
Megabit Modem 400F User Manual
Chapter 9: Technical Reference
RATE ADAPTIVE TRANSMISSION
The following definitions are useful for understanding the operation of the Megabit Modem:
•
Bit Error Rate (BER) is the ratio of received bits that are in error relative to the total number
of bits received, measured over time. For example, 10-7 BER means that on average one
error occurs per 107 bits received.
•
Signal to Noise Ratio (SNR) is the ratio (typically expressed in dB) of the received signal
power to the received noise power. It is a measure of the quality of the transmission.
•
Margin (SNR margin) is the amount of degradation in SNR that the system can tolerate
under the current conditions and still achieve 10-7 BER. A margin of 6 dB, for example,
means that the SNR can degrade by 6 dB and still provide a performance of 10-7 BER. The
Megabit Modem 400F have a margin configuration option that defaults to 3 dB, but can be
set anywhere between 0 to 15 dB.
•
Reach is the longest loop length that the system can support with a given margin.
Rate Adaptation
With ADC's rate adaptive technology, the Megabit Modem 400F can automatically startup or
adjust to the fastest speed possible, given the transmission distance and line conditions. Or, you
can set the modem to a specific rate.
Reach, Data Rate, SNR Margin, and Noise Environment
The maximum transmission rate of the Megabit Modem 400F is determined by distance, SNR
margin, and the condition of the line (wire gauge, condition noise environment). The figure on
page 73 shows the relationship between reach and data rate for a given set of conditions. The
plots can be used to determine the achievable reach at a given data rate, or they may be used to
determine the achievable data rates at a given distance. In all cases except the no noise case, a
margin of 4 dB was allocated above the SNR that provides a 10-7 BER.

Bridging and Routing
BRIDGING AND ROUTING
Bridging
You can configure the Megabit Modem 400F as a bridge to forward Ethernet data based on
MAC addresses.
MAC Layer Bridging
A bridge moves information across an internetwork from a source to a destination at the link
layer (of an OSI reference model). The information is sent to a physical address known as a
Media Access Control (MAC) address. The Megabit Modem 400F provides transparent
Ethernet MAC-layer bridging.
The bridge learns up to 1024 addresses. Additionally, when you configure the modem, you can
add 32 static addresses through the static MAC address configuration page.
Spanning Tree Protocol
The Megabit Modem 400F supports 802.1d Spanning Tree protocol which eliminates loops in
a LAN topology by partitioning out redundant links between LAN segments. This ensures that
there is only one path, or link, between any two nodes on the network. If this link goes down,
Spanning Tree re-enables partitioned links to create a new loop-free topology if possible.
An example of the active topology is shown on page 65. In the example, the spanning tree
algorithm partitions out the bridge from LAN A to LAN B, and creates the link from ENET2
to Bridge 5.

Bridging and Routing
Routing
You can configure the Megabit Modem 400F router to route Ethernet-encapsulated
IP datagrams based on IP addresses. Use Routing Information Protocol (RIP) to automatically
identify the route from the session on the Megabit Modem 400F to the destination. You can
specify the direction and version of RIP that allows other routers to update their routing tables
automatically (for example, information on 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.
The router also learns addresses. In addition to the addresses it learns, you can add 32 static
route entries on the LAN Brouter configuration page. Through the static IP routing feature, you
can configure the Megabit Modem 400F as an IP router with statically programmed route
entries. You can enable this function to provide broadcast filtering and to prevent eavesdropping
by specifying multiple destination gateways. When static IP routing is enabled, you can access
only specific remote IP subnets or hosts.
Since IP routers make forward or filter decisions based on the network-layer IP address instead
of the MAC hardware address, MAC-level broadcast frames are prevented from reaching
unwanted destinations in the network.
When setting parameters for an external router, configure a Static Route entry in any of the
external routers that may have been specified as a Default Router or as a Gateway. This
implementation prevents other parties from discovering routes through eavesdropping. The
format of this entry varies among the various router vendors, but is typically in the form of
"Destination," "Mask," and "Gateway," where the "Destination" is the remote IP Subnet or host
address, and "Gateway" is the IP address of the modem on the same subnet as the external
router.
Encapsulation for RFC 1483 Bridging/Routing
Most users select LLC, which allows you to run multiple protocols over the VC. An
encapsulation header identifies the types of protocol being carried in the transmission (for
example, IP). VC-MUX allows only one protocol to run over the VC. The type of protocol must
be negotiated between the modem and the service provider prior to the transmission. Because
there is only one protocol allowed, the header is not required. This configuration is normally
setup by the service provider.

MANAGEMENT PROTOCOLS
SNMP is used to configure system and bridge parameters, to monitor statistics, and to perform
advanced management tasks.
SNMP
This management protocol specifies how to send information between a network management
system (NMS) and managed devices on a network. Managed devices run a program called an
agent. The agent interprets SNMP requests and responds to them. The NMS communicates with
the agents in the managed devices to:
•
set configuration
•
get configuration
•
get status
A Management Information Base (MIB) defines the configuration and status parameters.
The Internet Engineering Task Force (IETF) specifies standard MIBs for certain types of
devices, ensuring any NMS can manage them. Additionally, vendors can issue proprietary
MIBs for their devices to fit specific needs.

ADSL MIB
PairGain Agent MIB

DNS RESOLUTION
If you want Domain Name System (DNS) resolution, you need to specify the IP address for a
device to be the DNS resolver. You can also specify another IP address to designate a second
device for a secondary DNS resolver. The DNS device maps human-readable addresses to IP
addresses. A human-readable address is one such as maggie.copro.company.com that
contains a host name and domain. The DNS resolver maps that name to the IP address that is a
numeric (four octet) value such as 192.168.30.25 (see page 43 for the example on how to
configure a DNS address).
TFTP SERVER
Trivial File Transfer Protocol (TFTP) is the TCP/IP standard for file transfer. It provides
the service with minimal capability and minimal overhead. TFTP uses UDP for
connectionless delivery.

Ethernet over thin coaxial cable.
AAL5
ATM Adaptation Layer 5.
ADSL
Asymmetric Digital Subscriber Line is a technology in which data is transferred from
the service provider to the subscriber at up to 7.552 Mbps, and transferred from
subscriber to service provider at up to 928 Kbps. ADSL is the implementation of the
physical layer for transmission of data.
ATM
Asynchronous Transfer Mode is a high bandwidth, low delay, connection-oriented,
packet-like switching and multiplexing technique that uses 53-byte fixed-size cells to
transmit voice, video and data over a network. ATM layers define how cells are
formatted and provides the transport of the fixed length cells between the modem
and the service provider (or endpoints of the virtual connection).
attenuation
The dissipation of the power of a transmitted signal as it travels over copper wire,
measured in decibels (dB).
BER
Bit Error Rate is a measure of transmission quality. The ratio of error bits to the total
number of bits transmitted.
bps
bit-per-second is the number of bits transferred during each second of data
transmission.
CBR
Constant Bit Rate is a Service Class for the modem. It provides constant bit rate data
with a timing relationship between the source and the destination. Also, a traffic class
that carries a guaranteed constant bandwidth. Best suited for applications that require
fixed bandwidth, such as uncompressed voice, video and circuit emulation. CBR is a
Quality of Service class defined by the ATM Forum for ATM networks.
cell
A fixed-length packet. Also, the unit of data transmission used in ATM. Each ATM cell
contains a fixed-size frame (53 bytes) consisting of a five-byte header and a 48-byte
payload.

string
A text string required for an SNMP trap to be received by a trap receiver(s). Also, a
text string that identifies an SNMP community and is associated with specific access
rights (read-only or read/write).
CRC
Cyclic Redundancy Check is a method used to verify the accuracy of data
transmission.
DMT
Discrete Multi-Tone is a modulation coding for an ADSL line. DMT is the modulation
technology used for the Megabit Modem 400F ADSL.
downstream
traffic

A protocol used for LAN traffic, which has a transfer rate of 10 or 100 Mbps.
flash memory
Non-volatile memory that can be erased and reprogrammed.
gateway
A device (generally a router) that provides translation services to allow
communication between two dissimilar networks.
IP
Internet Protocol is a TCP/IP protocol that controls packet transmission.
IP address
A 32-bit address used in IP routing. The address consists of four octets separated by
decimals. The octets comprise a network section, a subnet section (optional) and a
host section.
LAN
Local Area Network is a physically connected group of devices between which data
transmission occurs at high speeds over relatively short distances.
LLC
Logical Link Control is an encapsulation protocol for data that you transmit from the
modem over the WAN in 1483 Bridging/Routing mode.
LOF
Loss Of Frame is an error indicating that the receiving equipment has lost a frame.
LOS
Loss Of Signal is an error indicating that the receiving equipment has lost the signal.
MAC
Media Access Control is a physical address associated with a device such as a NIC.
For modem configuration, the MAC is used to map inbound traffic (from a remote IP
address) to an internal (LAN) IP address. Used with 1483 Bridging/Routing Mode.
margin
The noise margin in decibels that the modem must achieve with a BER of 10 -7 or
better to successfully complete initialization.
Megabit Modem 400F User Manual
Appendix D: Glossary
MIB
Management Information Base is a set of variables that define the configuration and
status parameters for network management. Network management stations can
retrieve information from and write information to an MIB. The Internet Engineering
Task Force (IETF) specifies standard MIBS for certain types of devices, ensuring any
NMS can manage the devices. Vendors can specify proprietary MIBs for their devices
to fit specific needs.
NAT
Network Address Translation provides the means to map private IP addresses to the
public IP addresses (proxy addresses) that are set up for the PPP sessions. Used with
PPP Mode. NAPT is Network Address and Port Translation.
NVRAM
Non-Volatile Random Access Memory is a medium for storing system configuration
information, so the information is not lost when the system is reset.
octet
A TCP/IP term indicating eight bits.
PAP/CHAP
With PAP, the modem sends authentication requests to the service provider and
authentication occurs only once during the life of the link.
In CHAP, the service provider returns an authentication challenge to the modem
during authentication. CHAP can be renegotiated during the life of the link. Also, both
the modem and the service provider must support clear text versions of the
password. The CHAP host field must be the same on both ends of the session.
PDU
Protocol Data Unit is data as it appears at the interface between a particular sublayer
and the sublayer immediately below.
POTS
Plain Old Telephone Service.
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.
