What You Will Choose

14 Megabit Modem 400F, 500L, 600F, and 700F User Manual

WHAT YOU WILL CHOOSE

Before configuring the modem, consider the options in the following “Configuration” section.

Ensure that you have the appropriate power cable for your facility as described below in the

“Power Cable” section.

Configuration

You can choose to use:

•Network Address Translation (NAT) protocol. This protocol includes both basic NAT and

Network Address Port Translaton (NAPT). Basic NAT uses a one-to-one mapping of a

private IP address and a public IP address. NAPT uses a multiple-to-one mapping of

multiple IP addresses and their ports to a single IP address and its ports. For more

information about the NAT protocol, see “NAT” on page 87.

•Domain Name System (DNS) resolution. You must specify the IP address for a device to

serve as the DNS resolver. You can also specify a second IP address to designate another

device to serve as a secondary DNS resolver. The DNS device maps human-readable

addresses to IP addresses. For simplicity and ease of management, use DNS relay. DNS

relay allows the LAN hosts to configure the Megabit Modem as the DNS server. Depending

on the host sending the DNS message and what session it is assigned to, the Megabit

Modem will relay the message to the appropriate DNS server. For more information about

DNS resolution, see “DNS Resolution” on page 93.

•TFTP server for downloading software updates to the modem. You specify the IP address,

subnet mask, and directory path (where software updates are located) for the device that

will be the TFTP server.

Power Cable

The Megabit Modem 400F, 500L, 600F, and 700F are available with a variety of power supplies

and power cords. When you order your modem, choose one of the following as the last number

in the product part number (example: use 150-2122-7x for the 700F) for your order to indicate

which power option you need:

•2 indicates a power supply for International use and does not include a power cord.

•3 indicates a power supply for North American use and includes a North American

power cord.

•4 indicates a Universal power supply and includes a European power cord.

•5 indicates a Universal power supply and includes a UK/Ireland power cord.

CONNECTING PHONE SERVICE

The Megabit Modem 400F, 500L, 600F, and 700F modem provide full support for the ITU

standard G.hs, G.dmt, and G.lite. In the traditional ADSL deployment, POTS splitters are

required to separate data transmission from phone service. In this case, the service provider will

supply you with a splitter. You will have one or more jacks for phone service and one jack for

ADSL data service. Connect your phones to the jacks indicated by the service provider for

phone service. However, using G.lite allows for splitterless deployment. In this case, you will

not need to install a splitter.

Selecting the System Mode of Operation

48 Megabit Modem 400F, 500L, 600F, and 700F User Manual

SELECTING THE SYSTEM MODE OF OPERATION

System mode indicates the mode of operation between the modem and the service provider

for WAN sessions. The only model capable of selecting between system modes is the Megabit

Modem 700F. It can operate in either Bridge/Router RFC 1483 or PPP over ATM mode. It can

not operate in both modes simultaneously. The Megabit Modem 400F operates only in

Bridge/Router RFC 1483 mode, while the Megabit Modem 500L and 600F operate only in PPP

over ATM mode. This section provides procedures to select the system mode. Then, use the

section “Saving the Configuration” on page 28 to effect the system mode of operation.

All sessions that occur simultaneously must be the same system mode: either PPP over ATM

or Bridge/Router RFC 1483. Your service provider will indicate which system mode you can use.

See the “System Mode Worksheet” on page 108 for the system mode that you recorded.

Point-to-Point Protocol (PPP) over ATM is connection-oriented where the session has to be

established between the modem and the service provider before data transmission begins.

Bridge/Router RFC 1483 does not establish a session. This mode switches packets based on the

data link-layer address for bridging or on the network-layer address for routing.

Information Description

Connection Name A unique descriptive identifier of the session that also displays in the connection

field.

ATM VPI Virtual Path Identifier (VPI) identifies the virtual path that transports ATM cells in a

virtual Channel. The range of values is 0 to 15.

ATM VCI Virtual Channel Idenifier (VCI) identifies a virtual channel for each session (each

session is a virtual channel). Can be a number from 32 up to a maximum of 253 (on

VPI 0, VCIs 254 and 255 are reserved), with the first 32 (0 through 31) reserved.

Primary DNS IP address of Domain Name Service device that translates names into numeric IP

addresses. This is the device at the service provider that the modem will translate

requests.

Secondary DNS IP address of a secondary Domain Name System device that translates names into

numeric IP addresses.

Address Translation Enables/disables the use of Network Address Translation (NAT) protocol to translate

private IP addresses to public IP addresses assigned to each session.

InBound NAT Default IP address of the designated NAT default user for inbound traffic. When the NAT

engine does not have enough information to do the inbound translation, it forwards

the inbound packet to the NAT default user.

Continuous Retry Enables/disables the Continuous Retry function of the PPP session establishment

process. When Continuous Retry is enabled, the PPP engine continuously retries

establishing the PPP session until one of the following is true:

•The PPP session is established successfully. The session status then goes to the

UP state.

•Authentication fails during the handshaking. The session status then goes to the

LogInErr state.

•The PPP session is disconnected. The session status then goes to the DOWN

state.

Always ON When enabled, the PPP engine establishes/maintains the session even when there

are no users assigned to it. When disabled, the PPP engine will not establish or will

terminate the session when there are no users assigned to it.

Session Enable If enabled, the session is active and is ready to establish the PPP link. If disabled, the

session is not active.

Address Assignment Determines whether the session IP address is assigned by the service provider

(Dynamic) or entered by the user (Fixed).

MAINTENANCE AND

TROUBLESHOOTING

MAINTENANCE

You can update software by specifying a device on your LAN where you will place new

software for the update (see “Defining TFTP Parameters” on page 36). Then, use the procedure

“Updating Software” on page 77 to download new software from the TFTP device to the

Megabit Modem 400F, 500L, 600F, and 700F.

Through the RS-232 MGMT port on the Megabit Modem 600F and 700F, you can change the

modem LAN port IP address and network mask, the default gateway IP address, and the IP

address for the device on the LAN that can administer the modem (see page 80).

Updating Software

Updating software images in binary format require the use of a TFTP server. The TFTP server

stores the files which will be downloaded to your modem. This guide assumes that you have

correctly set up your TFTP server on the same subnet as the modem and that the appropriate

files are available to download.

When updating software remotely, file corruption is a major concern. For example, if an image

file altered during the TFTP process the modem may not restore its connections after a system

reset. To eliminate such possibilities, the modem software performs a CRC check for the

integrity of each file after it has been downloaded.

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.

TRANSMISSION ON THE WIDE AREA NETWORK

ATM over DMT ADSL is the technology that provides the high-speed transmission between

the modem and the service provider. This transmission occurs over a single-pair telephone line.

The following sections describe these technologies.

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. The VPI and VCI provide the virtual connection between the modem

and the service provider. The VPI identifies the Virtual Path (VP) that transports ATM cells in

a Virtual Channel (VC). The Megabit Modem 400F, 500L, 600F, and 700F 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 VPI value must always be 0.

SYSTEM MODE ENCAPSULATION

Point-to-Point Protocol (PPP) over ATM or RFC 1483 Bridging/Routing are the two protocols

you can use to encapsulate data for transport across the ADSL WAN. The following sections

describe these protocols.

PPP

PPP runs over ATM virtual circuits. PPP exists between the hardware layer and the

network-layer interface protocols. It is a widely used protocol for establishing connections on

the WAN. PPP provides the set up and release of connections for each session. PAP/CHAP

provide the authentication for the PPP sessions.

In PPP over ATM mode, you can map private IP address LAN users to PPP sessions using RFC

1631 Network Address Translation protocol.

PAP/CHAP Authentication Security

Password Authentication Protocol (PAP) and Challenge-Handshake Authentication Protocol

(CHAP) are two ways to authenticate PPP sessions. PAP and CHAP are both offered since some

systems support only PAP. With PAP, the modem sends authentication requests to the service

provider and authentication occurs only once during the life of the link.

With 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.

NAT

RFC 3022 Network Address Translation (NAT) includes two operations. They are Basic NAT

and Network Address Port Translation (NAPT).

Basic NAT only deals with IP addresses. Therefore, it is a one-to-one private IP address to

public IP address (proxy address) mapping. Basic NAT allows you to hide your private

addresses behind the public IP addresses assigned to a session. Corporations that need flexibility

using different IP address ranges can benefit from this operation, as the private IP addresses will

remain the same when the public IP addresses are reassigned.

System Mode Encapsulation

88 Megabit Modem 400F, 500L, 600F, and 700F User Manual

NAPT does not have the limitation of using only the IP address in the translation. It also uses

TCP/UDP ports. It is a method that allows multiple IP addresses and their TCP/UDP ports to be

translated into one IP address and its ports. A good candidate for NAPT is a small office with

multiple hosts but one public IP address. In this case, NAPT allows the entire office to use the

public IP address to communicate out of the private network.

An example of NAPT in this small office envionment is the RealPlayer™ application. The

RealPlayer (client at the office) initiates a TCP connection to the RealServer™ on the Internet,

which then initiates a UDP connection back to RealPlayer. RealPlayer can then tell the server

to use a specific UDP port for the UDP connection. The user should set up a static NAT entry

for the UDP connection for RealPlayer to work properly through NAPT.

Bridging

You can configure the Megabit Modem 400F and 700F as a bridge to forward Ethernet data

based on MAC addresses.

MAC Layer Bridging

A bridge moves information across a network from a source to a destination at the data 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 and 700F provide 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 and 700F support 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 89. 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.

Routing

You can configure the Megabit Modem 400F and 700F 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 and 700F 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. RIP Version 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 and 700F 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.

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.

Management Protocols

92 Megabit Modem 400F, 500L, 600F, and 700F User Manual

MIB and Trap Support

Each managed device has configuration, status, and statistical information that defines its

functionality and operational capabilities. These elements make up the MIB for the device being

managed. The MIB defines the kind of information an NMS can retrieve from a managed

device, and the settings an NMS can control in a managed device.

Model Number supports the following MIBs:

•RFC 1213: "Management Information Base for Network Management of TCP/IP-Based

Internet: MIB-II" Supported groups: system, interfaces, IP, ICMP, UDP, and SNMP

groups.

•RFC 1215: "A Convention for Defining Traps for Use with the SNMP" Supported groups:

ColdStart, linkUp, linkDown, and authenticationFailure traps. Link status traps are sent for

events related to Ethernet.

•RFC 1493: "Definition of Managed Objects for Bridges" Supported groups: Base,

Spanning Tree, and transparent bridging groups. The Spanning Tree MIB can only be

accessed if the Spanning Tree protocol is enabled.

•ADSL MIB

•ATM MIB

•ADC 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.

In previous versions of code, the provisioning of more than one PPP over ATM session required

the manual configuration of DNS server addresses on the host computers. Changing from one

session to another session also required manual configuration. This is because different sessions

required different DNS server addresses, and the modem did not have a way to handle the DNS

server address on a session by session basis.

DNS Relay solves this problem. With DNS Relay, the DNS server addresses are configured on

a per session basis and all the hosts on the LAN have their DNS server addresses configured to

the same address, the LAN IP address of the modem. Therefore, multiple hosts in different

sessions configured for DHCP can receive the modem’s LAN IP address as the DNS server

address. When a host sends out a DNS message to the modem, the modem looks up the source

IP address in the User Assignment Table to determine the host’s session and the DNS server for

that session. The modem replaces the destination IP address of the frame with the DNS server

address configured for that session and sends the frame on its way.

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.

A TFTP Server is a device on the network which stores files that other IP devices can access for

file transfer using the TFTP protocol. The Megabit Modem is one of these IP devices and uses

theTFTP server to download updated software in binary format.

Typical TFTP servers are not dedicated only for file transfer. Frequently, Microsoft Windows

desktops are used to store the binary files. To create a TFTP server, several shareware programs

are available through the Internet. Once you have selected and installed the TFTP server

software, configure it to share a directory containing the binary files. To configure the Megabit

Modem to access the TFTP server, see Chapter 9 on page 77.

ENCAPSULATION

Selection of an encapsulation protocol from the modem to the service provider occurs on a

per virtual circuit (session) basis. For example, for the 700F you can configure 32 sessions for

PPP over ATM mode and configure another 32 sessions for RFC 1483 mode. However, you can

activate only PPP over ATM sessions or RFC 1483 sessions at a time. You cannot concurrently

activate PPP sessions and RFC 1483 sessions for all Megabit Modems.

When you activate RFC 1483 system mode, you can select WAN encapsulation as VC-MUX

for some sessions and LLC for other sessions.

PPP

Link Control Protocol

(LCP) Provides a phase of the PPP negotiation by setting up the physical link (RFC

1661).

Network Control

Protocol (NCP) Occurs after LCP, negotiating parameters for each network interface and uses

Internet Protocol Control Protocol (IPCP) which is defined in RFC 1332.

Authentication

(PAP/CHAP) Provides authentication of PPP sessions for security through Password and

Challenge-Handshake Authentication Protocols (RFC 1994).

Network Address

Translation Network Address Port Translation (NAPT) maps LAN side private IP address to

the public IP address assigned to the 32 virtual channels (RFC 1631). You can

map to two private addresses to each of the 32 sessions for a total of 64

addresses.

Routing

Routing Protocol Supports RFC 1724 Routing Information Protocol (RIP and RIP Version 2).

Encapsulation Supports Logical Link Control (LLC) or VC-based multiplexing (RFC 1483).

Static Routes Supports up to 32 static routes

Address Resolution Supports Address Resolution Protocol (ARP) over the LAN port (RFC 826)

GLOSSARY

10/100BASE-T The Institute of Electrical and Electronic Engineers (IEEE) 802.3 specification for

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).

authentication Security feature offered through PAP and CHAP with PPP sessions.

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.

118 Megabit Modem 400F, 500L, 600F, and 700F User Manual

community

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, 500L, 600F, and 700F ADSL.

downstream

traffic Communications from a service provider to a user.

encapsulation The inclusion of data in a protocol header prior to transmission, which enables

successful data transmission between different protocol networks.

ES Errored Seconds is the seconds during which errors occur that prevent the payload

from being corrected.

Ethernet 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.

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.

NAPT Network Address and Port Translation provides the means to map private IP

addresses and TCP/UDP ports to the public IP addresses (proxy addresses) and

TCP/UDP ports that are set up for the PPP sessions. Used with PPP Mode.

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 Password Authentication Protocol and Challenge Handshake Authentication Protocol

are two ways to authenticate PPP sessions. 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.

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 Megabit Modem 400F, 500L, 600F,

and 700F 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.

UDP User Datagram Protocol is a transport protocol used to map inbound traffic (from a

remote IP address) to an internal (LAN) IP address. Uses a protocol port number for

the destination at the remote location.

upstream traffic Communications from a user to a service provider.

VCI Virtual Channel Identifier is a 16-bit field addressing identifier in the header of an ATM

cell used to route cell traffic. It identifies a particular VC link for a given VP.

VCMUX Virtual Channel Multiplexer-based encapsulation used for networks with large

numbers of virtual channels making it practical to carry a single protocol per virtual

channel.

VC A Virtual Channel is a logical connection in the ATM network over which ATM cells are

transmitted.

VPI Virtual Path Identifier is an 8-bit field addressing identifier in the header of an ATM

cell that is used to route cell traffic. It identifies a particular VP link.

VP A Virtual Path is a group of VCs carried between two points. The VP provides a means

of bundling traffic traveling in the same direction. VPs are defined by a unique VPI

value.

WAN Wide Area Network is a network consisting of nodes located across a large

geographical area. Also, the connection between a service provider and Megabit 700F

Modem.
