Before the TDM-C504 ADSL2/2+ Modem Router will pass any data between the LAN interface(s) and the

WAN interface, the WAN side of the modem must be configured. Depending upon your ADSL service

provider or your ISP, you will need some (or all) of the information outlined below before you can properly

configure the WAN:

 Your ADSL account Username and Password

 Your ADSL line VPI and VCI setting

 Your ADSL encapsulation type or multiplexing (Either LLC or VC. Check your ISP for detail)

 Your ADSL Training Mode or Handshaking Mode (default is MMODE)

For PPPoA or PPPoE users, you also need these values from your ISP:

 Your account Username

 Your account Password

For RFC 1483 users, you may need these values from your ISP:

 Your ADSL fixed Internet IP address

 Your Subnet Mask

 Your Default Gateway address

 Your primary DNS IP address

Since multiple users can use the TDM-C504 ADSL2/2+ Modem Router, the TDM-C504 ADSL2/2+ Modem

Router can simultaneously support multiple connection types; hence, you must set up different profiles for

each connection. The TDM-C504 ADSL2/2+ Modem Router supports the following protocols:

 PPPoE

 PPPoA

 1483 Bridged

 1483 MER

 1483 Routed

The WAN setup configuration page enable the user to create, save, delete and select connection profiles as

required. (In many cases, only one connection profile will be required and only one connection profile will be

used at one time).

Bridge Mode

ADSL router is bridge mode enabled by factory default. There is a 1483-bridged mode PVC 5/35 in system.

1483 Bridged: When 1483 Bridged mode is selected, the following screen will pop-up. A Bridged connection

basically disables the routing, firewall and NAT features of the 4 Ports ADSL2/2+ Router. In a 1483 Bridged

connection, the 4 Ports ADSL2/2+ Router acts as a modem or hub, and just transmits packets between the

WAN interface and the LAN interface. A 1483 Bridged connection assumes that another device is providing

the routing functionality that is now disabled in the 4 Ports ADSL2/2+ Router.

LLC and VC-Mux are two different methods of encapsulating the PPP packet. Contact your ISP to make

sure which encapsulation is being supported.

 Channel:

; VPI: Virtual Path Identifier is a virtual path used for cell routing that is identified by an 8-bit

field in the ATM cell header. The VPI field specifies this 8-bit identifier for routing.

; VCI: A Virtual Channel Identifier is a virtual channel that is identified by a unique numerical

tag that is defined by a 16-bit field in the ATM cell header. The purpose of the virtual

channel is to identify where the cell should travel. The VCI field specifies this 16-bit

numerical tag that determines the destination.

; Encapsulation: There are 2 Encapsulation type:

 LLC

 VC-Mux Note: LLC and VC-Mux are two different methods of encapsulating the PPP packet.

MER(Mac Encapsulation Routing) Mode

1483 MER: 1483 MER also commonly known as 1483 Bridged Router mode. When 1483 MER mode is

selected, the following screen will pop-up. Most Internet users are provided with a dynamic IP address by

their ISP for each session, however certain situations call for a Fixed (Or Static) IP address. Fixed (Or Static)

is used whenever a known Fixed (Or Static) IP is assigned. The accompanying information such as the

Subnet mask and the gateway should also be specified. Up to three Domain Name Server (DNS) addresses

can also be specified. These servers would enable you to have access to other web servers. Valid IP

addresses range is from 0.0.0.0 to 255.255.255.255.

 Channel:

; VPI: Virtual Path Identifier is a virtual path used for cell routing that is identified by an 8-bit

field in the ATM cell header. The VPI field specifies this 8-bit identifier for routing.

; VCI: A Virtual Channel Identifier is a virtual channel that is identified by a unique numerical

DHCP Settings

You can configure your network and DSL device to use the Dynamic Host Configuration Protocol (DHCP).

This page provides DHCP instructions for implementing it on your network by selecting the role of DHCP

protocol that this device wants to play. There are two different DHCP roles that this device can act as: DHCP

Server and DHCP Relay. When acting as DHCP server, you can setup the server parameters at the DHCP

Server page; while acting as DHCP Relay, you can setup the relay at the DHCP Relay page.

DHCP Server configuration

By default, the device is configured as a DHCP server, with a predefined IP address pool of 192.168.10.64

through 192.168.10.253 (subnet mask 255.255.255.0).

Field Description

IP Pool Range Specify the lowest and highest addresses in the pool.

Max Lease Time The Lease Time is the amount of time that a network user is allowed to maintain a

network connection to the device using the current dynamic IP address. At the end of

the Lease Time, the lease is either renewed or a new IP is issued by the DHCP

server. The amount of time is in units of seconds. The default value is 86400

seconds (1 day). The value –1 stands for the infinite lease.

Domain Name A user-friendly name that refers to the group of hosts (subnet) that will be assigned

addresses from this pool.

IGMP Proxy

Multicasting is useful when the same data needs to be sent to more than one hosts. Using multicasting as

opposed to sending the same data to the individual hosts uses less network bandwidth. The multicast feature

also enables you to receive multicast video stream from multicast servers.

IP hosts use Internet Group Management Protocol (IGMP) to report their multicast group memberships to

neighboring routers. Similarly, multicast routers use IGMP to discover which of their hosts belong to multicast

groups. This device supports IGMP proxy that handles IGMP messages. When enabled, this device acts as a

proxy for a LAN host making requests to join and leave multicast groups, or a multicast router sending

multicast packets to multicast group on the WAN side.

When a host wishes to join a multicast group, it sends IGMP REPORT message to the device’s IGMP

downstream interface. The proxy sets up a multicast route for the interface and host requesting the video

content. It then forwards the Join to the upstream multicast router. The multicast IP traffic will then be

forwarded to the requesting host. On a leave, the proxy removes the route and then forwards the leave to the

upstream multicast router.

The IGMP Proxy page allows you to enable multicast on WAN and LAN interfaces. The LAN interface is

always served as downstream IGMP proxy, and you can configure one of the available WAN interfaces as the

upstream IGMP proxy.

 Upstream: The interface that IGMP requests from hosts is sent to the multicast router.

 Downstream: The interface data from the multicast router are sent to hosts in the multicast

group database.

Field Description

Proxy Interface The upstream WAN interface is selected here.

Apply Changes

Click to save the setting to the configuration.

UPnP

The DSL router supports a control point for Universal Plug and Play (UPnP) version 1.0, and supports two key

features: NAT Traversal and Device Identification. This feature requires one active WAN interface. In

addition, the host should support this feature. In the presence of multiple WAN interfaces, select an interface

on which the incoming traffic is present.

With NAT Traversal, when an UPnP command is received to open ports in NAT, the application translates the

request into system commands to open the ports in NAT and the firewall. The interface to open the ports on is

given to UPnP when it starts up and is part of the configuration of the application.

For Device Identification, the application will send a description of the DSL device as a control point back to

the host making the request.

RIP

RIP is an Internet protocol you can set up to share routing table information with other routing devices on your

LAN, at your ISP’s location, or on remote networks connected to your network via the ADSL line.

Most small home or office networks do not need to use RIP; they have only one router, such as the ADSL

Router, and one path to an ISP. In these cases, there is no need to share routes, because all Internet data

from the network is sent to the same ISP gateway.

You may want to configure RIP if any of the following circumstances apply to your network:

− Your home network setup includes an additional router or RIP-enabled PC (other than the ADSL

Router). The ADSL Router and the router will need to communicate via RIP to share their routing

tables.

− Your network connects via the ADSL line to a remote network, such as a corporate network. In order

for your LAN to learn the routes used within your corporate network, they should both be configured

with RIP.

− Your ISP requests that you run RIP for communication with devices on their network..

Routing

The Routing page enables you to define specific route for your Internet and network data.

Most users do not need to define routes. On a typical small home or office LAN, the existing routes that set up

the default gateways for your LAN hosts and for the DSL device provide the most appropriate path for all your

Internet traffic.

− On your LAN hosts, a default gateway directs all Internet traffic to the LAN port(s) on the DSL device.

− On the DSL device itself, a default gateway is defined to direct all outbound Internet traffic to a route

You may need to define routes if your home setup includes two or more networks or subnets, if you connect

to two or more ISP services, or if you connect to a remote corporate LAN.

Your LAN hosts know their default gateway either because you assigned it to them when you

modified your TCP/IP properties, or because you configured them to receive the information

dynamically from a server whenever they access the Internet.

at your ISP. The default gateway is assigned either automatically by your ISP whenever the device

negotiates an Internet access, or manually by user to setup through the configuration.

Field Description

Enable Check to enable the selected route or route to be added.

Destination The network IP address of the subnet. The destination can be specified as the IP

address of a subnet or a specific host in the subnet. It can also be specified as all

zeros to indicate that this route should be used for all destinations for which no other

route is defined (this is the route that creates the default gateway).

Subnet Mask The network mask of the destination subnet. The default gateway uses a mask of

0.0.0.0.

Next Hop The IP address of the next hop through which traffic will flow towards the destination

subnet.

Metric Defines the number of hops between network nodes that data packets travel. The

default value is 0, which means that the subnet is directly one hop away on the local

LAN network.

Interface The WAN interface to which a static routing subnet is to be applied.

Port Mapping

The DSL device provides multiple interface groups. Up to five interface groups are supported including one

default group. The LAN and WAN interfaces could be included. Traffic coming from one interface of a group

can only be flowed to the interfaces in the same interface group. Thus, the DSL device can isolate traffic from

group to group for some application. By default, all the interfaces (LAN and WAN) belong to the default group,

and the other four groups are all empty. It is possible to assign any interface to any group but only one group.

Appendix A

Router Terms

What is a firewall?

A firewall is a device that protects one network from another, while allowing communication between the two.

A firewall incorporates the functions of the NAT router, while adding features for dealing with a hacker

intrusion or attack. Several known types of intrusion or attack can be recognized when they occur. When an

incident is detected, the firewall can log details of the attempt, and can optionally send email to an

administrator notifying them of the incident. Using information from the log, the administrator can take action

with the ISP of the hacker. In some types of intrusions, the firewall can fend off the hacker by discarding all

further packets from the hacker’s IP address for a period of time.

What is NAT?

NAT stands for Network Address Translation. Another name for it is Connection Sharing. What does this

mean? Your ISP provides you with a single network address for you to access the Internet through. However,

you may have several machines on your local network that want to access the Internet at the same time. The

router provides NAT functionality that converts your local network addresses to the single network address

provided by your ISP. It keeps track of all these connections and makes sure that the correct information gets

to the correct local machine.

Occasionally, there are certain programs that don't work well through NAT. Some games, and some specialty

applications have a bit of trouble. The router contains special functionality to handle the vast majority of these

troublesome programs and games. NAT does cause problems when you want to run a SERVER though.

When running a server, please see the DMZ section below.

What is a DMZ?

DMZ really stands for Demilitarized Zone. It is a way of separating out part of your local network so that is

more open to the Internet. Suppose that you want to run a web-server, or a game server. Normal servers like

these are blocked from working by the NAT functionality. The solution is to "isolate" the single local computer

into a DMZ. This makes the single computer look like it is directly on the Internet, and others can access this

machine.

Your machine isn't really directly connected to the Internet, and it really has an internal local network address.

When you provide the servers network address to others, you must provide the address of the router. The

router "fakes" the connection to your machine.

You should use the DMZ when you want to run a server that others will access from the Internet. Internal

programs and servers (like print servers, etc) should NOT be connected to the DMZ

What is a Gateway?

The Internet is so large that a single network cannot handle all of the traffic and still deliver a reasonable level

of service. To overcome this limitation, the network is broken down into smaller segments or subnets that can

deliver good performance for the stations attached to that segment. This segmentation solves the problem

of supporting a large number of stations, but introduces the problem of getting traffic from one subnet to

another.

To accomplish this, devices called routers or gateways are placed between segments. If a machine wishes to

contact another device on the same segment, it transmits to that station directly using a simple discovery

technique. If the target station does not exist on the same segment as the source station, then the source

actually has no idea how to get to the target.

One of the configuration parameters transmitted to each network device is its default gateway. This address

is configured by the network administrators and it informs each personal computer or other network device

where to send data if the target station does not reside on the same subnet as the source. If your machine

can reach all stations on the same subnet (usually a building or a sector within a building), but cannot

communicate outside of this area, it is usually because of an incorrectly configured default gateway.

Frequently Asked Questions

The Frequently Asked Questions addresses common questions regarding TDM-C504 ADSL2/2+ Modem

Router settings.

Some of these questions are also found throughout the guide, in the sections to which they reference.

1. How do I determine if a link between the Ethernet card (NIC) and the TDM-C504 A DSL2/2+

Modem Router has been established?

Ans. A ping test would determine if a connection is established between your TDM-C504 ADSL2/2+

Modem Router and computer. Using, the ping command, ping the IP address of the TDM-C504

ADSL2/2+ Modem Router, in this case, 192.168.1.1 (default). For more information on Ping Testing, refer

to Appendix C: Troubleshooting Guide. Alternatively, if the Ethernet LINK LED is solidly on, then the

Ethernet link is established.

2. How do I determine if a link between the TDM-C504 ADSL2/2+ Modem Router and the Internet has

been established?

Ans. Similar to the previous question, a ping test would determine whether or not a connection is

established. However, this time use a URL instead of and IP Address, such as www.google.com

Alternatively, if the ADSL LED is solidly on, then the ADSL link is established.

3. I can’t get the Internet game, server, or application to work properly. Ans. If you are having difficulties getting any Internet game, server, or application to function properly,

consider exposing one computer to the Internet using DeMilitarized Zone (DMZ) setting. Refer to

Service–Firewall–DMZ section for the setting detail.

4. I need to upgrade the firmware. Ans. In order to upgrade the firmware with the latest features, check with your local dealer or ISP for

technical support.

5. I forgot my password. Ans. Reset the TDM-C504 ADSL2/2+ Modem Router to factory default by pressing the Reset button for

more than 5 seconds and then releasing it.

6. What is MAC Address?

Ans.Short for Media Access Control Address. It is a hardware address that uniquely identifies each

node of a Ethernet networking device. This address is usually permanent.

7. What is NAT (Netw ork Address Translation) and what is it used for? Ans.NAT translates multiple IP Address on the private LAN to one public IP Address (in WAN) that is sent

out to the Internet. NAT adds a level security since the IP address of a PC connected to the private LAN is

never transmitted on the Internet.

ATM: Asynchronous Transfer Mode: A method of transfer in which data is organized into 53-byte cell units.

ATM cells are processed asynchronously in relation to other cells.

BC: Broadcast: Communication in which a sender transmits to everyone in the network. BER: Bit Error Rate: Percentage of Bits that contain errors relative to the total number of bits transmitted. Bridge: A device that connects two networks and decides which network the data should go to. Bridge Mode: Bridge Mode is used when there is one PC connected to the LAN-side Ethernet or USB port.

IEEE 802.1D method of transport bridging is used to bridge between the WAN (ADSL) side and the LAN

(Ethernet or USB) side, i.e., to store and forward.

CBR: Constant Bit Rate: A constant transfer rate that is ideal for streaming (executing while still downloading)

data, such as audio or video files.

Cell: A unit of transmission in ATM, consisting of a fixed-size frame containing a 5-octet header and a

48-octet payload.

CHAP: Challenge Handshake Authentication Protocol: Typically more secure than PAP, CHAP uses

username and password in combination with a randomly generated challenge string which has to be

authenticated using a one-way hashing function.

CLP: Cell Loss Priority: ATM cells have two levels of priority, CLP0 and CLP1. CLP0 is of higher priority, and

in times of high traffic congestion, CLP1 error cells may be discarded to preserve the Cell Loss Ratio of the

CLP0 cells.

CO: Central Office: In a local loop, a Central Office is where home and office phone lines come together and

go through switching equipment to connect them to other Central Offices. The distance from the Central

Office determines whether or not an ADSL signal can be supported in a given line.

CPE: Customer Premises Equipment. This specifies equipment on the customer, or LAN, side. CRC: Cyclic Redundancy Checking: A method for checking errors in a data transmission between two

computers. CRC applies a polynomial function (16 or 32-bit) to a block of data. The result of that polynomial is

appended to the data transmission. Upon receipt, the destination computer applies the same polynomial to

the block of data. If the host and destination computer share the same result, the transmission was

successful. Otherwise, the sender is notified to re-send the data block.

DHCP: Dynamic Host Configuration Protocol: A communications protocol that allows network administrators

to manage and assign IP addresses to computers within the network. DHCP provides a unique address to a

computer in the network which enables it to connect to the Internet through Internet Protocol (IP). DHCP can

lease and IP address or provide a permanent static address to those computers who need it (servers, etc.).

DMZ: Demilitarized Zone: A computer Host or network that acts as a neutral zone between a private network

and a public network. A DMZ prevents users outside of the private network from getting direct access to a

server or any computer within the private network. The outside user sends requests to the DMZ, and the DMZ

initiates sessions in the public network based on these requests. A DMZ cannot initiate a session in the

private network, it can only forward packets to the private network as they are requested.

DNS: Domain Name System: A method to locate and translate Domain Names into Internet Protocol (IP)

addresses, where a Domain Name is a simple and meaningful name for an Internet address.

DSL: Digital Subscriber Line: A technology that provides broadband connections over standard phone lines. DSLAM: Digital Subscriber Line Access Multiplexer: Using multiplexing techniques, a DSLAM receives

signals from customer DSL lines and places the signals on a high-speed backbone line. DSLAMs are

typically located at a telephone company’s CO (Central Office).

Encapsulation: The inclusion of one data structure within another. For example, packets can be

encapsulated in an ATM frame during transfer.

FEC: Forward Error Correction: An error correction technique in which a data packet is processed through an

algorithm that adds extra error correcting bits to the packet. If the transmitted message is received in error,

these bits are used to correct the errored bits without retransmission.

Firewall: A firewall is a method of implementing common as well as user defined security policies in an effort

to keep intruders out. Firewalls work by analyzing and filtering out IP packets that violate a set of rules

defined by the firewall administrator. The firewall is located at the point of entry for the network. All data

inbound and outbound must pass through the firewall for inspection.

Fragmentation: Breaking a packet up into smaller packets that is caused either by the transmission medium

being unable to support the original size of the packet or the receiving computer not being able to receive a

packet of that size. Fragmentation occurs when the sender’s MTU is larger than the receiver’s MRU.

FTP: File Transfer Protocol. A standardized internet protocol which is the simplest way to transfer files from

one computer to another over the internet. FTP uses the Internet’s TCP/IP protocols to function.

Full Duplex: Data transmission can be transmitted and received on the same signal medium and at the same

time. Full Duplex lines are bidirectional.

G.dmt: Formally G.992.1, G.dmt is a form of ADSL that uses Discrete MultiTone (DMT) technology. G.dmt

incorporates a splitter in its design.

G.lite: Formally G.992.2, G.lite is a standard way to install ADSL service. G.lite enables connections speeds

up to 1.5 Mbps downstream and 128 kbps upstream. G.lite does not need a splitter at the user end because

splitting is preformed at the remote end (telephone company).

Gateway: A point on the network which is an entrance to another network. For example, a router is a

gateway that connects a LAN to a WAN.

Half Duplex: Data transmission can be transmitted and received on the same signal medium, but not

simultaneously. Half Duplex lines are bidirectional.

HEC: Headed Error Control: ATM error checking by using a CRC algorithm on the fifth octet in the ATM cell

header to generate a check character. Using HEC, either a single bit error in the header can be corrected or

multiple bit errors in the header can be detected.

HNP: Home Network Processor Host: In context of Internet Protocol, a host computer is one that has full two way access to other computers

on the Internet.

IAD: Integrated Access Device: A device that multiplexes and demultiplexes communications in the CPE

onto and out of a single telephone line for transmission to the CO.

IP: Internet Protocol: The method by which information is sent from one computer to another through the

Internet. Each of these host computers have a unique IP address which distinguishes it from all the other

computers on the internet. Each packet of data sent includes the sender’s IP address and the receiver’s IP

address.

LAN: Local Area Network: A group of computers, typically covering a small geographic area, that share

devices such as printers, hard disk drives, scanners, and optical drives. Computers in a LAN typically share

an internet connection through some sort of router that connects the computers to a WAN.

LLC: Logical Link Control: Provides an interface point to the MAC sublayer. LLC Encapsulation is needed

when several protocols are carried over the same Virtual Circuit.

MAC Address: Media Access Control Address: A unique hardware number on a computer or device that

identifies it and relates it to the IP address of that device.

MC: Multicast: Communication involving a single sender and multiple specific receivers in a network. MRU: Maximum Receive Unit: MRU: Maximum Receive Unit (MRU) is the largest size packet that can be

received by the modem. During the PPP negotiation, the peer of the PPP connection will indicate its MRU

and will accept any value up to that size. The actual MTU of the PPP connection will be set to the smaller of

the two (MTU and the peer’s MRU). In the normal negotiation, the peer will accept this MRU and will not send

packet with information field larger than this value.

MSS: Maximum Segment Size: The largest size of data that TCP will send in a single, unfragmented IP

packet. When a connection is established between a LAN client and a host in the WAN side, the LAN client

and the WAN host will indicate their Maximum Segment Size during the TCP connection handshake.

MTU: Maximum Transmission Unit: The largest size packet that can be sent by the modem. If the network

stack of any packet is larger than the MTU value, then the packet will be fragmented before the transmission.

During the PPP negotiation, the peer of the PPP connection will indicate its MRU and will accept any value up

to that size. The actual MTU of the PPP connection will be set to the smaller of the two (MTU and the peer’s

MRU).

NAPT: Network Address and Port Translation: An extension of NAT, NAPT maps many private internal

addresses into one IP address. The outside network (WAN) can see this one IP address but it cannot see the

individual device IP addresses translated by the NAPT.

NAT: Network Address Translation: The translation of an IP address of one network to a different IP address

known by another network. This gives an outside (WAN) network the ability to distinguish a device on the

inside (LAN) network, as the inside network has a private set of IP address assigned by the DHCP server not

known to the outside network.

PAP: Password Authentication Protocol: An authentication protocol in which authorization is done through a

user name and password.

PDU: Protocol Data Unit: A frame of data transmitted through the data link layer 2. Ping: Packet Internet Groper: A utility used to determine whether a particular device is online or connected to

a network by sending test packets and waiting for a response.

PPP: Point-to-Point Protocol: A method of transporting and encapsulating IP packets between the user PC

and the ISP. PPP is full duplex protocol that is transmitted through a serial interface.

Proxy: A device that closes a straight connection from an outside network (WAN) to an inside network (LAN).

All transmissions must go through the proxy to get into or out of the LAN. This makes the internal addresses

of the devices in the LAN private.

PVC: Permanent Virtual Circuit: A software defined logical connection in a network; A Virtual Circuit that is

permanently available to the user.

RIP: Routing Information Protocol: A management protocol that ensures that all hosts in a particular network

share the same information about routing paths. In a RIP, a host computer will send its entire routing table to

another host computer every X seconds, where X is the supply interval. The receiving host computer will in

turn repeat the same process by sending the same information to another host computer. The process is

repeated until all host computers in a given network share the same routing knowledge.

RIPv1: RIP Version 1: One of the first dynamic routing protocols introduced used in the internet, RIPv1 was

developed to distribute network reach ability information for what is now considered simple topologies.

RIPv2: RIP Version 2: Shares the same basic concepts and algorithms as RIPv1 with added features such as

subnet masks, authentication, external route tags, next hop addresses, and multicasting in addition to

broadcasting.

Router Mode: Router Mode is used when there is more than one PC connected to the LAN-side Ethernet

and/or USB port. This enables the ADSL WAN access to be shared with multiple nodes on the LAN. Network

Address Translation (NAT) is supported so that one WAN-side IP address can be shared among multiple

LAN-side devices. DHCP is used to serve each LAN-side device and IP address.

SNAP: SubNetwork Attachment Point. SNMP: Simple Network Management Protocol: Used to govern network management and monitor devices

on the network. SNMP is formally described in RFC 1157.

SNR: Signal-to-Noise Ratio: Measured in decibels, SNR is a calculated ratio of signal strength to background

noise. The higher this ratio, the better the signal quality.

Subnet Mask: Short for SubNetwork Mask, subnet mask is a technique used by the IP protocol to filter

messages into a particular network segment, called a subnet. The subnet mask consists of a binary pattern

that is stored in the client computer, server, or router. This pattern is compared with the incoming IP address

to determine whether to accept or reject the packet.

TCP: Transfer Control Protocol: Works together with Internet Protocol for sending data between computers

over the Internet. TCP keeps track of the packets, making sure that they are routed efficiently.

TFTP: Trivial File Transfer Protocol: A simple version of FTP protocol that has no password authentication or

directory structure capability.

Trellis Code: An advanced method of FEC (Forward Error Correction). When enabled, it makes for better

error checking at the cost of slower packet transmission. Setting Trellis Code to Disabled will cause increased

packet transmission with decreased error correction.

TTL: Time To Live: A value in an IP packet that indicates whether or not the packet has been propagating

through the network too long and should be discarded.

UBR: Unspecified Bit Rate: A transfer mode that is usually used in file transfers, email, etc. UBR can vary

depending on the data type.

USB: Universal Serial Bus: A standard interface between a computer and a peripheral (printer, external

drives, digital cameras, scanners, network interface devices, modems, etc.) that allows a transfer rate of

12Mbps.

UDP: User Datagram Protocol: A protocol that is used instead of TCP when reliable delivery is not required.

Unlike TCP, UDP does not require an acknowledgement (handshake) from the receiving end. UDP sends

packets in one-way transmissions.

VBR-nrt: Variable Bit Rate – non real time: With VBR-nrt, cell transfer is variable upon certain criteria. VC: Virtual Circuit: A virtual circuit is a circuit in a network that appears to be a physically discrete path, but is

actually a managed collection of circuit resources that allocates specific circuits as needed to satisfy traffic

requirements.

VCI: Virtual Channel Identifier: A virtual channel identified by a unique numerical tag that is defined by a

16-bit field in the ATM cell header. The purpose of the virtual channel is to identify where the cell should

travel.

VC-Mux: Virtual Circuit based Multiplexing: In VC Based Multiplexing, the interconnect protocol of the carried

network is identified implicitly by the VC (Virtual Circuit) connecting the two ATM stations (each protocol must

be carried over a separate VC).

VPI: Virtual Path Identifier: Virtual path for cell routing indicated by an eight bit field in the ATM cell header.

WAN: Wide Area Network: A WAN covers a large geographical area. A WAN is consisted of LANs and the

Internet is consisted of WANs.
