What is DSL?

DSL (Digital Subscriber Line) technology enhances the data capacity of the existing telephone line running between the local telephone company switching offices and most homes and offices. While the wire itself can handle higher frequencies, the telephone switching equipment is designed to cut off signals above 4,000Hz to filter noise from the voice line. DSL services are either symmetrical (traffic flows at the same speed in both directions) or asymmetrical (the downstream capacity is higher than the upstream capacity).
As the carrying distance increases, data rates decrease. That means that users who are beyond a certain distance from the telephone company’s central office may not be able to obtain the higher speeds for DSL maximum transmission distances. A DSL connection is a point-to-point dedicated circuit, meaning that the link is always up and there is no dialing required.
What is ADSL?
ADSL is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstream data rate. This works well for a typical Internet session in which more information is downloaded, e.g., from Web servers, than is uploaded. ADSL operates in a frequency range that is above the frequency range of voice services, so the two systems can operate over the same cable.

2.3 Additional Installation Requirements
In addition to the contents of your package, there are other hardware and software requirements you need before you can install and use your Prestige. These requirements include:
z A computer with Ethernet 10Base-T/100Base-T NIC.
z A computer equipped with communications software (for example, Hyper Terminal in Win98)
configured to the following parameters:
¾ VT100 terminal emulation.
¾ 9600 Baud rate.
¾ No parity, 8 Data bits, 1 Stop bit.
¾ Flow Control set to None
After the Prestige has been successfully connected to your network, you can make future changes to the configuration through the telnet application.

2.4 Connecting a POTS Splitter

This is for the Prestige following the Full Rate (G.dmt) standard only. One major difference between ADSL and dial-up modems is the optional telephone splitter. This device keeps the telephone and ADSL signals separated, giving them the capability to provide simultaneous Internet access and telephone service on the same line. Splitters also eliminate the destructive interference conditions caused by telephone sets. The purchase of a POTS splitter is optional.
Noise generated from a telephone in the same frequency range as the ADSL signal can be disruptive to the ADSL signal. In addition the impedance of a telephone when off-hook may be so low that it shunts the strength of the ADSL signal. A POTS splitter will filter the telephone signals before combining the ADSL and telephone signals transmitted and received. The issues of noise and impedance are eliminated with a single POTS splitter installation.
A telephone splitter is easy to install as shown in the following figure.

3.3.1 Wizard Setup — PPPoE Modem Screen
The screen shown next appears if you selected PPPoE Modem from the initial Wizard screen and allows you to enter Internet Access information in one screen. Before you configure your Prestige for Internet access, you need to collect your Internet account information from your ISP and telephone company. Refer to the next table for a list of required account information.
A Note about IP Adressess.
Every machine on the Internet must have a unique address. If your networks are isolated from the Internet, e.g., only between your two branch offices, you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks:
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
3-4 Web Configurator
Page 27
Prestige 642 PPPoE Modem
You can obtain your IP address from the IANA, from an ISP or assigned from a private network. If you belong to a small organization and your Internet access is through an ISP then ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization then you should consult your network administrator for the appropriate IP addresses.
Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address assignment,
please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466,
Guidelines for Management of IP Address Space.
A Note about VPI and VCI Numbers
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers supplied by the telephone company. The valid range for the VPI is 1 to 255 and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic). Please see the VPI & VCI Appendix for more information

3.4.3 Advanced Setup — LAN Screen
Click the Advanced Setup link and then click the LAN link to display the screen shown next.
DHCP
DHCP (Dynamic Host Configuration Protocol) allows individual clients (computers) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS servers to Windows 98, Windows NT and other systems that support the DHCP client. The Prestige can also act as a surrogate DHCP server where it relays IP address assignments from the actual DHCP server to clients.
IP Pool Setup
The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64 for the client computers. This leaves 31 IP addresses, 192.168.1.2 to 192.168.1.32 (excluding the Prestige itself which has a default IP of 192.168.1.1), for other server computers, e.g., server for mail, FTP, telnet, web, etc., that you may have.
DNS
DNS Server Address DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa, e.g., the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The DNS server addresses that you enter in the DHCP setup are passed to the client computers along with the assigned IP address and subnet mask. There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a customer the DNS server addresses, usually in the form of an information sheet, when
Web Configurator 3-11
Page 34
Prestige 642 PPPoE Modem
s/he signs up. If your ISP does give you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup, otherwise, leave them blank. If the Primary and Secondary DNS Server fields in DHCP Setup are not specified, i.e., left as 0.0.0.0, the Prestige tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS query to the Prestige, the Prestige forwards the query to the real DNS server learned through IPCP and relays the response back to the computer. Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does not mean you can leave the DNS servers out of the DHCP setup under all circumstances.
IP Address
If the ISP did not explicitly give you an IP network number, then you most likely have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0 (ignoring the trailing zero) and you must enable the Single User Account feature of the Prestige (it is enabled by default).
The subnet mask specifies the network number portion of an IP address. Your Prestige will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the Prestige unless you are instructed to do otherwise.

3.4.5 Advanced Setup — NAT (Network Address Translation) Applications
Click the Advanced Setup link and then click the NAT Applications link to display the screen shown next.
Network Address Translation (NAT)
Typically, if there are multiple users on the LAN that want concurrent access to the Internet, you must lease a block of legal or globally unique IP addresses from an ISP. The NAT feature lets you enjoy the same benefits
3-14 Web Configurator
Page 37
Prestige 642 PPPoE Modem
as having multiple legal addresses, but only pay for one IP address, thus saving significantly on subscription fees (check with your ISP before you enable this feature). The IP address for the NAT can be either fixed or dynamically assigned by the ISP. In addition, you can designate servers, e.g., a web server and a Telnet server, on your local network and make them accessible to the outside world (see below). If you do not define a server, NAT offers the additional benefit of firewall protection. If no server is defined, all incoming inquiries will be filtered out by your Prestige, thus preventing intruders from probing your network. Your Prestige accomplishes address sharing by translating the internal LAN IP addresses to a single address that is globally unique on the Internet. For more information on IP address translation, refer to RFC 1631 - The IP
Network Address Translator (NAT).
Multiple Servers behind NAT
Even though NAT makes your whole inside network appear as a single computer to the outside world, A service is identified by the port number; the following table shows the most common services and their corresponding port numbers.
Table 3-7 Common Services and Corresponding Port Numbers
SERVICES PORT NUMBER
FTP (File Transfer Protocol) 21
Telnet 23
SMTP (Simple Mail Transfer Protocol) 25
DNS (Domain Name System) 53
HTTP (Hyper Text Transfer Protocol or WWW Web) 80
PPTP (Point-to-Point Tunneling Protocol) 1723
So, if you have a web server at IP address 192.168.1.2 and a FTP server at IP address 192.168.1.3, then you need to specify port 80 (web) for the server at IP address 192.168.1.2 and port 21 (FTP) for the FTP server at IP address 192.168.1.3.
A server can support more than one service, e.g., a server can provide both FTP and DNS service, while another provides only web service. Furthermore, since you need to specify the IP address of a server in the Prestige, a server must have a fixed IP address and not be a DHCP client whose IP address potentially changes each time it is turned on.
In addition to servers for specific services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default server is not defined, the service request is simply discarded. To make a server visible to the outside world, specify the port number of the service in the Port Number field and the inside IP address of the server in the Server IP Address field.
The Prestige has some of the more popular applications already pre-configured. Select an application from the drop-down list box and the corresponding port number should display in the Port Number field. To

4.2 Command Structure
4.2.1 Conventions for Using CI Commands
General Conventions
CI commands may be typed in a variety of ways depending on what you want to configure, display, etc.
The conventions for typing in most CI commands are shown next.
command <interface|device> subcommand [parameter] command subcommand [parameter] ?|help command ?|help commmand subcommand ?|help
Syntax Conventions
CI command keywords are in regular courier font and should be typed in as they appear or in
abbreviated form (see the next section).
Required fields (parameters) in a CI command are enclosed in “<>” brackets. For example,
P642ME-13> set ppp password <xxxxxxxx> <VC#>
Optional fields (parameters) in a CI command are enclosed in “[]” brackets. For example,
P642ME-13>device dial [node#]
The “|” symbol is shorthand for the word “or”. For example, sys log online [on|off]

4.2.2 Using Abbreviated CI Commands
Some CI commands have abbreviated forms that allow quicker Prestige configuration (and fewer keystrokes). Type enough of a CI command to distinguish it from other CI commands. For example, typing the sys v CI command is the same as typing sys version. On the other hand, typing the sys trc CI command will cause the Prestige to temporarily hang because this command can’t distinguish itself from sys trcdisp, sys trc log or sys trcpacket CI commands. Shown next, are some examples of abbreviated CI commands.

Chapter 5

Firmware and Configuration Maintenance

This chapter tells you how to back up and restore your configuration file as well as upload new
firmware and a new configuration file.
5.1 Filename Conventions
The configuration file (often called the romfile or rom-0) contains the factory default settings in the menus such as password, DHCP Setup, TCP/IP Setup, etc. It arrives from ZyXEL with a rom filename extension. Once you have customized the Prestige's settings, they can be saved back to your computer under a filename of your choosing.
ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) is the system firmware and has a “bin” filename extension. With many ftp and tftp clients, the filenames are similar to those seen next.
ftp> put firmware.bin ras
This is a sample ftp session showing the transfer of the computer file " firmware.bin" to the Prestige.
ftp> get rom-0 config.cfg
This is a sample ftp session saving the current configuration to the computer file config.cfg.
If your [t]ftp client does not allow you to have a destination filename different than the source, you will need to rename them as the Prestige only recognizes “rom-0” and “ras”. Be sure you keep unaltered copies of both files for later use.
The following table is a summary. Please note that the internal filename refers to the filename on the Prestige and the external filename refers to the filename not on the Prestige, that is, on your computer, local network or ftp site and so the name (but not the extension) will vary. After uploading new firmware see the ZyNOS F/W Version field in the System Status screen to confirm that you have uploaded the correct firmware version.

FTP over WAN will not work if security level 2 or 3 is enabled.
5.2 Backup Configuration
Backup is highly recommended once your Prestige is functioning properly. FTP and TFTP are the preferred methods for backing up your current configuration to your computer since FTP and TFTP are faster. Any serial communications program should work fine; however, you must use Xmodem protocol to perform the download/upload and you don’t have to rename the files (see section 5.1).
Please note that terms “download” and “upload” are relative to the computer. Download means to transfer from the Prestige to the computer, while upload means from your computer to the Prestige.
5.2.1 Backup Configuration Using FTP
Follow the instructions shown next.
5.2.2 Using the FTP command from the DOS Prompt
Step 1. Launch the FTP client on your computer.
Step 2. Enter “open”, followed by a space and the IP address of your Prestige.
Step 3. Press [ENTER] when prompted for a username.
Step 4. Enter your password as requested (the default is 1234).
Step 5. Enter “bin” to set transfer mode to binary.
5-2 Firmware and Configuration File Maintenance
Page 67
Prestige 642 PPPoE Modem
Step 6. Use “get” to transfer files from the Prestige to the computer, for example, “get rom-0 config.rom”
transfers the configuration file on the Prestige to your computer and renames it “config.rom”. See earlier in this chapter for more information on filename conventions.
Step 7. Enter “quit” to exit the ftp prompt.
Step 8. Enter “atgo” to restart the Prestige.

Prestige 642 PPPoE Modem
5.2.3 Backup Configuration Using TFTP
The Prestige supports the up/downloading of the firmware and the configuration file using TFTP (Trivial File Transfer Protocol) over LAN. Although TFTP should work over WAN as well, it is not recommended.
To use TFTP, your computer must have both telnet and TFTP clients. To backup the configuration file, follow the procedure shown next:
Step 1. Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not have
any security checks, the Prestige records the IP address of the telnet client and accepts TFTP requests only from this address.
Step 2. Enter the Command Line Interface by following the instructions in the Command Line Interface
chapter.
Step 3. Enter command “sys stdio 0” to disable the console timeout, so the TFTP transfer will not be
interrupted. Enter command “sys stdio 5” to restore the five-minute console timeout (default) when the file transfer is complete.
Step 4. Launch the TFTP client on your computer and connect to the Prestige. Set the transfer mode to
binary before starting data transfer.
Step 5. Use the TFTP client (see the example below) to transfer files between the Prestige and the
computer. The file name for the configuration file is “rom-0” (rom-zero, not capital o).
Note that the telnet connection must be active and the Prestige in CI mode before and during the TFTP transfer. For details on TFTP commands (see following example), please consult the documentation of your TFTP client program. For UNIX, use “get” to transfer from the Prestige to the computer and “binary” to set binary transfer mode.
5.2.4 TFTP Command Example
The following is an example tftp command:
TFTP [-i] host get rom-0 config.rom
where “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the Prestige IP address, “get” transfers the file source on the Prestige (rom-0 name of the configuration file on the Prestige) to the file destination on the computer and renames it config.rom.
Third Party TFTP Clients
The following table describes some of the fields that you may see in third party TFTP clients.

5.4.2 TFTP File Upload
The Prestige also supports the uploading of firmware files using TFTP (Trivial File Transfer Protocol) over LAN. Although TFTP should work over WAN as well, it is not recommended.
To use TFTP, your computer must have both telnet and TFTP clients. To transfer the firmware and the configuration file, follow the procedure shown next.
Step 1. Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not have
any security checks, the Prestige records the IP address of the telnet client and accepts TFTP requests only from this address.
Step 2. Enter the Command Line Interface by following the instructions in the Command Line Interface
chapter.
Step 3. Enter the command “sys stdio 0” to disable the console timeout, so the TFTP transfer will not be
interrupted. Enter “command sys stdio 5” to restore the five-minute console timeout (default) when the file transfer is complete.
Step 4. Launch the TFTP client on your computer and connect to the Prestige. Set the transfer mode to
binary before starting data transfer.
Step 5. Use the TFTP client (see the example below) to transfer files between the Prestige and the
computer. The file name for the firmware is “ras”.
Note that the telnet connection must be active and the Prestige in CI mode before and during the TFTP transfer. For details on TFTP commands (see following example), please consult the documentation of your TFTP client program. For UNIX, use “get” to transfer from the Prestige to the computer, “put” the other way around, and “binary” to set binary transfer mode.
TFTP Upload Command Example
The following is an example tftp command:
TFTP [-i] host put firmware.bin ras
where “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the Prestige’s IP address, “put” transfers the file source on the computer (firmware.bin – name of the firmware on the computer) to the file destination on the remote host (ras - name of the firmware on the Prestige).
Commands that you may see in third party TFTP clients are listed earlier in this chapter.
5.4.3 Uploading Files Via Console Port
FTP or TFTP are the preferred methods for uploading firmware to your Prestige. However, if your network is down, uploading files is only possible with a direct connection to your Prestige via the console port. Uploading files via the console port under normal conditions is not recommended since FTP or TFTP is

faster. Any serial communications program should work fine; however, you must use the Xmodem protocol to perform the upload.
Example Xmodem Firmware Upload Using HyperTerminal
Step 1. Enter the Command Line Interface by following the instructions in the Command Line Interface
chapter.
Step 2. Enter “r s”.
Step 3. Enter “atur”.
Step 4. Run the HyperTerminal program. Click Transfer, then Send File as shown in the following
screen.
Step 5. After the "Starting Xmodem upload" message appears, activate the Xmodem protocol on your
computer. Follow the procedure as shown previously for the HyperTerminal program. The procedure for other serial communications programs should be similar.
Step 6. Click Transfer, then Send File to display the following screen.
Type the firmware file’s location, or click Browse to look for it.
Choose the Xmodem protocol.
Then click Send.
Figure 5-8 Example Xmodem Upload
After the firmware upload process has completed, the Prestige will automatically restart.
FTP over WAN will not work if security level 2 or 3 is enabled.

Appendix A
VPI & VCI
This appendix describes VPI and VCI.
ATM is a connection-oriented technology, meaning that it sets up virtual circuits over which end systems communicate. The terminology for virtual circuits is as follows:
z Virtual Channel Logical connections between end stations
z Virtual Path A bundle of virtual channels
Think of a virtual path as a cable that contains a bundle of wires. The cable connects two points, and wires within the cable provide individual circuits between the two points. In an ATM cell header, a VPI (Virtual Path Identifier) identifies a link formed by a virtual path and a VCI (Virtual Channel Identifier) identifies a channel within a virtual path. The VPI and VCI are identified and correspond to termination points at ATM switches as shown. Your telephone company should supply you with these numbers.

Dynamic Host Configuration Protocol automatically assigns IP addresses to clients when they log on. DHCP centralizes IP address management on central computers that run the DHCP server program. DHCP leases addresses, for a period of time, which means that past addresses are “recycled” and made available for future reassignment to other systems.
The unique name that identifies an Internet site. Domain Names always have two or more parts that are separated by dots. The part on the left is the most specific and the part on the right is the most general.
Dynamic RAM (Random Access Memory) stores information in capacitors that must be refreshed periodically.
Digital Subscriber Line technologies enhance the data capacity of the existing twisted pair wire that runs between the local telephone company switching offices and most homes and offices. There are actually seven types of DSL service, ranging in speeds from 16 Kbits/sec to 52 Mbits/sec. The services are either symmetrical (traffic flows at the same speed in both directions) or asymmetrical (the downstream capacity is higher than the upstream capacity). DSL connections are point-to-point dedicated circuits, meaning that they are always connected There is no dial-up. There is also no switching, which means that the line is a direct connection into the carrier’s frame relay, ATM (Asynchronous Transfer Mode) or Internet-connect system.
A Digital Subscriber Line Access Multiplexor (DSLAM) is a network device, usually at a telephone company central office, that receives signals from multiple customer Digital Subscriber Line connections and puts the signals on a high-speed backbone line using multiplexing techniques. Depending on the product, DSLAM multiplexers connect DSL lines with some combination of asynchronous transfer mode ATM, frame relay or IP networks.

A very common method of networking computers in a LAN. There are a number of adaptations to the IEEE 802.3 Ethernet standard, including adaptations with data rates of 10 Mbits/sec and 100 Mbits/sec over coaxial cable, twisted-pair cable and fiber-optic cable. The latest version of Ethernet, Gigabit Ethernet, has a data rate of 1 Gbit/sec.
Frequently Asked Questions. FAQs are documents that list and answer the most common questions on a particular subject.
The FCC (Federal Communications Commission) is in charge of allocating the electromagnetic spectrum and thus the bandwidth of various communication systems.
A gateway is a computer system or other device that acts as a translator between two systems that do not use the same communication protocols, data formatting structures, languages, and/or architecture.
Any computer on a network that is a repository for services available to other computers on the network. It is quite common to have one host machine provide several services, such as WWW and USENET.
Internet Assigned Number Authority acts as the clearing house to assign and coordinate the use of numerous Internet protocol parameters such as Internet addresses, domain names, protocol numbers, and more. Use a search engine to find the current IANA web site.
Internet Control Message Protocol is a message control and error-reporting protocol between a host server and a gateway to the Internet ICMP uses Internet Protocol (IP) datagrams, but the messages are processed by the TCP/IP software and are not directly apparent to the application user.
(Upper case “I”). The vast collection of inter-connected networks that use TCP/IP protocols evolved from the ARPANET (Advanced Research Projects Agency Network) of the late 1960’s and early 1970’s.
(Lower case “i”). Any time you connect two or more networks together, you have an internet.
A private network inside a company or organization that uses the same kinds of software that you would find on the public Internet, but that is only for internal use.
Internet Protocol. (Currently IP version 4 or IPv4). The underlying protocol for routing packets on the Internet and other TCP/IP-based networks.
IP Control Protocol allows changes to IP parameters such as the IP address. Internet Service Providers provide connections into the Internet for home users and
businesses. There are local, regional, national, and global ISPs. You can think of local ISPs as the gatekeepers into the Internet.
Local Area Network is a shared communication system to which many computers are

attached. A LAN, as its name implies, is limited to a local area. This has to do more with the electrical characteristics of the medium than the fact that many early LANs were designed for departments, although the latter accurately describes a LAN as well. LANs have different topologies, the most common being the linear bus and the star configuration.
Light Emitting Diode. LEDs are visual indicators that relay information about the status of specific MI1951 functions to the user by lighting up, turning off or blinking. LEDs are usually found on the front panel of the physical device. Examples include Status, Power and System LEDS.

One VC carries multiple protocols with protocol identifying information being contained in each packet header. Despite the extra bandwidth and processing overhead, this method my be advantageous if it is not practical to have a separate VC for each carried protocol, eg., if charging heavily depends on the number of simultaneous VCs.
Loop reach defines speed that can be attained at various distances. This is very important for DSL technology as distance from the CO (Central Office) influences attainable speeds.
On a local area network (LAN) or other network, the MAC (Media Access Control) address is a computer's unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address). The MAC layer frames data for transmission over the network, then passes the frame to the physical layer interface where it is transmitted as a stream of bits.
Multiplexors or MUXs, as they are often called, are devices that combine signals from various sources such as PBX (Private Branch Exchange), asynchronous terminals or a bridge connected to a WAN. A multiplexor transmits these signals as a single data stream over a digital line. Multiplexors, among other tasks, conserve bandwidth.
Network Address Translation is the translation of an Internet Protocol address used within one network to a different IP address known within another network - see also SUA.
Any time you connect two or more computers together, allowing them to share resources, you have a computer network. Connect two or more networks together and you have an internet.
Network Interface Card. A board that provides network communication capabilities to and from a computer system. Also called an adapter.
Any single computer connected to a network. Password Authentication Protocol is a security protocol that requires users to enter a
password before accessing a secure system. The user’s name and password are sent over the wire to a server where they are compared with a database of user account

POTS
PPP
Post Office Protocol. This is a common protocol used for sending, receiving, and delivering mail messages.
An Internet port refers to a number that is part of a URL, appearing after a colon (:), directly following the domain name. Every service on an Internet server listens on a particular port number on that server. Most services have standard port numbers, e.g. Web servers normally listen on port 80.
An interface on a computer for connecting peripherals or devices to the computer. A printer port, for example, is an interface that is designed to have a printer connected to it. Ports can be defined by specific hardware (such as a keyboard port) or through software.
Plain Old Telephone Service is the analog telephone service that runs over copper twisted-pair wires and is based on the original Bell telephone system. Twisted-pair wires connect homes and businesses to a neighborhood central office. This is called the local loop. The central office is connected to other central offices and long-distance facilities.
Point to Point Protocol. PPP encapsulates and transmits IP (Internet Protocol) datagrams over serial point-to-point links. PPP works with other protocols such as IPX (Internetwork Packet Exchange). The protocol is defined in IETF (Internet Engineering Task Force) RFC 1661 through 1663. PPP provides router-to-router, host-to-router, and host-to-host connections.
PPPoE
Protocol
PSTN
F Glossary
PPPoE (Point-to-Point Protocol over Ethernet) relies on two widely accepted standards: PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the Internet through a common broadband medium, such as a single DSL line, wireless device or cable modem. All the users over the Ethernet share a common connection, so the Ethernet principles supporting multiple users in a LAN combine with the principles of PPP, which apply to serial connections. From authentication, accounting and secure access to configuration management, PPPoE supports a broad range of existing applications and services.
A “language” for communicating on a network. Protocols are sets of standards or rules used to define, format and transmit data across a network. There are many different protocols used on networks. For example, most web pages are transmitted using the HTTP protocol.
Public Switched Telephone Network was put into place many years ago as a voice telephone call-switching system. The system transmits voice calls as analog signals across copper twisted cables from homes and businesses to neighborhood COs (central

offices); this is often called the local loop. The PSTN is a circuit-switched system, meaning that an end-to-end private circuit is established between caller and callee.
Permanent Virtual Circuit. A PVC is a logical point-to-point circuit between customer sites. PVCs are low-delay circuits because routing decisions do not need to be made along the way. Permanent means that the circuit is preprogrammed by the carrier as a path through the network. It does not need to be set up or torn down for each session.
An RFC (Request for Comments) is an Internet formal document or standard that is the result of committee drafting and subsequent review by interested parties. Some RFCs are informational in nature. Of those that are intended to become Internet standards, the final version of the RFC becomes the standard and no further comments or changes are permitted. Change can occur, however, through subsequent RFCs.
Routing Information Protocol is an interior or intra-domain routing protocol that uses distance-vector routing algorithms. RIP is used on the Internet and is common in the NetWare environment as a method for exchanging routing information between routers.
In telephony, a splitter, sometimes called a “plain old telephone service splitter" is a device that divides a telephone signal into two or more signals, each carrying a selected frequency range, and can also reassemble signals from multiple signal sources into a single signal
Shielded Twisted-Pair cable consists of copper-core wires surrounded by an insulator. Two wires are twisted together to form a pair; the pair form a balanced circuit. The twisting prevents interference problems, STP provides protection against external crosstalk.
A cable that wires a pin to its equivalent pin. This cable connects two dissimilar devices, for example, a data terminal equipment (DTE) device and a data communications equipment (DCE) device. A straight through Ethernet cable is the most commonly used Ethernet cable.

Transmission Control Protocol is a connection-oriented transport service that ensures the reliability of message delivery. It verifies that messages and data were received.
Telnet is the login and terminal emulation protocol common on the Internet and in UNIX environments. It operates over TCP/IP networks. Its primary function is to allow users to log into remote host systems.
A device that allows you to send commands to a computer somewhere else. At a minimum, this usually means a keyboard, display screen and some simple circuitry.

commands to a computer somewhere else. Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP (File
Transfer Protocol), but it is scaled back in functionality so that it requires fewer resources to run. TFTP uses the UDP (User Datagram Protocol) rather than TCP (Transmission Control Protocol).
Two insulated wires, usually copper, twisted together and often bound into a common sheath to form multi-pair cables. In ISDN, the cables are the basic path between a subscriber's terminal or telephone and the PBX or the central office.
User Datagram Protocol. DP is a connectionless transport service that dispenses with the reliability services provided by TCP. UDP gives applications a direct interface with the Internet Protocol (IP) and the ability to address a particular application process running on a host via a port number without setting up a connection session.
Uniform Resource Locator. URL is an object on the Internet or an intranet that resides on a host system. Objects include directories and an assortment of file types, including text files, graphics, video and audio. A URL is the address of an object that is normally typed in the Address field of a Web browser. A URL is basically a pointer to the location of an object.
By prior mutual agreement, each protocol is assigned to a specific virtual circuit, eg., VCI carries IP, VC2 carries IPX, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical.
A Virtual Channel Identifier is a number that denotes a particular logical connection between end stations (users or networks). See also, VPI.
A Virtual Path Identifier is a number that denotes a bundle of virtual channels. See also VCI.
Virtual Private Network. These networks use public connections (such as the Internet) to transfer information. That information is usually encrypted for security purposes.
Wide Area Networks link geographically dispersed offices in other cities or around the globe. Just about any long-distance communication medium can serve as a WAN link including switched and permanent telephone circuits, terrestrial radio systems and satellite systems.
World Wide Web. Frequently used (incorrectly) when referring to "The Internet". WWW has two major definitions. One, the whole constellation of resources that can be accessed using Gopher, FTP, HTTP, telnet, USENET, WAIS and other tools. Two, the universe of hypertext servers (HTTP servers).
Digital Subscriber Line(s) where x, when specified, denotes a particular flavor of DSL, eg., ADSL, G.SHDSL, SDSL, VDSL, RDSL, etc.
