Getting To Know the ZyXEL
This chapter introduces the main features and applications of the ZyXEL Device.

1.1 Overview

The P-2608HWL-Dx series are Integrated Access Devices (IADs) that combine an ADSL2+ router with Voice over IP (VoIP) communication capabilities. This guide covers the following models.

P-2608HWL-D1 P-2608HWL-D3 P-2608HWL-D7
See Appendix A on page 361 for a complete list of software features.

1.1.1 VoIP Features

You can use the ZyXEL Device to make and receive VoIP telephone calls:
Figure 1 ZyXEL Device’s VoIP Features
• Peer-to-Peer calls (A) - Use the ZyXEL Device to make a call to the recipient’s IP address without using a SIP proxy server.
• Calls via a VoIP service provider (B) - The ZyXEL Device sends your call to a VoIP service provider’s SIP server which forwards your calls to either VoIP or PSTN phones.

1.1.2 DSL Router

Your ZyXEL Device is an ideal solution for fast Internet access. Computers can connect to the ZyXEL Device’s LAN ports (or wirelessly) and use it as a gateway to the Internet.
Figure 2 Internet Access
You can also configure firewall and content filtering on the ZyXEL Device for secure Internet access. When the firewall is on, all incoming traffic from the Internet to your network is blocked unless it is initiated from your network. This means that probes from the outside to your network are not allowed, but you can safely browse the Internet and download files.
Use content filtering to block access to web sites, with URL’s containing keywords that you specify. You can define time periods and days during which content filtering is enabled and include or exclude particular computers on your network from content filtering. For example, you could block access to certain web sites for the kids.
Use bandwidth management to efficiently manage traffic on your network by giving priority to certain types of traffic and/or to particular computers. For example, you could make sure that the ZyXEL Device gives voice over Internet calls high priority, and/or limit bandwidth devoted to the boss’s excessive file downloading.

VoIP Wizard And Example

This chapter shows you how to configure your SIP account(s) and make a VoIP phone call.

4.1 Introduction

The ZyXEL Device has Voice over IP (VoIP) communication capabilities that allow you to use a traditional analog telephone to make Internet calls. You can configure the ZyXEL Device to use up to two SIP based VoIP accounts.
This section describes how you can set up your ZyXEL Device to call someone who is also using a VoIP device. Make sure your telephone is connected to the Phone 1 port before you start with our example.

account is registered and active. After it is registered, they need to provide you with their SIP number. You can use your VoIP service provider’s dialing plan to call SIP numbers.
You can also use your VoIP service provider’s dialing plan to call regular phone numbers. You dial a prefix number, provided to you by your VoIP service provider, followed by a regular phone number.

CHAPTER 5

Bandwidth Management Wizard

This chapter shows you how to configure basic bandwidth management using the wizard screens.

5.1 Introduction

Bandwidth management allows you to control the amount of bandwidth going out through the ZyXEL Device’s WAN port and prioritize the distribution of the bandwidth according to service bandwidth requirements. This helps keep one service from using all of the available bandwidth and shutting out other users.

5.2 Predefined Media Bandwidth Management Services

The following is a description of the services that you can select and to which you can apply media bandwidth management using the wizard screens.
Table 16 Media Bandwidth Management Setup: Services
SERVICE DESCRIPTION
WWW The World Wide Web (WWW) is an Internet system to distribute graphical, hyper-
linked information, based on Hyper Text Transfer Protocol (HTTP) - a client/server protocol for the World Wide Web. The Web is not synonymous with the Internet; rather, it is just one service on the Internet. Other services on the Internet include Internet Relay Chat and Newsgroups. The Web is accessed through use of a browser.
FTP File Transfer Program enables fast transfer of files, including large files that may
not be possible by e-mail. FTP uses TCP (Transmission Control Protocol) port number 21.
E-Mail Electronic mail consists of messages sent through a computer network to specific
groups or individuals. Here are some default ports for e-mail: POP3 - port 110 IMAP - port 143 SMTP - port 25 HTTP - port 80
Telnet 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. Telnet uses TCP port 23.

VoIP (H.323) Sending voice signals over the Internet is called Voice over IP or VoIP.
TFTP Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP, but
A multimedia communications product from Microsoft that enables groups to teleconference and videoconference over the Internet. NetMeeting supports VoIP, text chat sessions, a whiteboard, and file transfers and application sharing.
NetMeeting uses H.323. H.323 is a standard teleconferencing protocol suite that provides audio, data and video conferencing. It allows for real-time point-to-point and multipoint communication between client computers over a packet-based network that does not provide a guaranteed quality of service.
H.323 is transported primarily over TCP, using the default port number 1720.
Initiated Protocol (SIP) is an internationally recognized standard for implementing VoIP. SIP is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet.
SIP is transported primarily over UDP but can also be transported over TCP, using the default port number 5060.

7.1 WAN Overview

A WAN (Wide Area Network) is an outside connection to another network or the Internet.

7.1.1 Encapsulation

Be sure to use the encapsulation method required by your ISP. The ZyXEL Device supports the following methods.
P-2608HWL-Dx Series User’s Guide
CHAPTER 7

WAN Setup

7.1.1.1 ENET ENCAP
The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the IP network protocol. IP packets are routed between the Ethernet interface and the WAN interface and then formatted so that they can be understood in a bridged environment. For instance, it encapsulates routed Ethernet frames into bridged ATM cells. ENET ENCAP requires that you specify a gateway IP address in the ENET ENCAP Gateway field in the second wizard screen. You can get this information from your ISP.
7.1.1.2 PPP over Ethernet
The ZyXEL Device supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPPoE option is for a dial-up connection using PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example RADIUS).
One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site.
Chapter 7 WAN Setup 89
Page 90
P-2608HWL-Dx Series User’s Guide
By implementing PPPoE directly on the ZyXEL Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.
7.1.1.3 PPPoA
PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA connection functions like a dial-up Internet connection. The ZyXEL Device encapsulates the PPP session based on RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the Internet Service Provider’s (ISP) DSLAM (digital access multiplexer). Please refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information on PPP.
7.1.1.4 RFC 1483
RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5). The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual circuit (VC-based multiplexing). Please refer to RFC 1483 for more detailed information.

7.1.2 Multiplexing

There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the multiplexing method required by your ISP.
7.1.2.1 VC-based Multiplexing
In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical.
7.1.2.2 LLC-based Multiplexing
In this case one VC carries multiple protocols with protocol identifying information being contained in each packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on the number of simultaneous VCs.

7.1.3 VPI and VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255 and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic). Please see the appendix for more information.
90 Chapter 7 WAN Setup
Page 91
P-2608HWL-Dx Series User’s Guide

7.1.4 IP Address Assignment

A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different one each time. The Single User Account feature can be enabled or disabled if you have either a dynamic or static IP. However the encapsulation method assigned influences your choices for IP address and ENET ENCAP gateway.
7.1.4.1 IP Assignment with PPPoA or PPPoE Encapsulation
If you have a dynamic IP, then the IP Address and ENET ENCAP Gateway fields are not applicable (N/A). If you have a static IP, then you only need to fill in the IP Address field and not the ENET ENCAP Gateway field.
7.1.4.2 IP Assignment with RFC 1483 Encapsulation
In this case the IP Address Assignment must be static with the same requirements for the IP Address and ENET ENCAP Gateway fields as stated above.
7.1.4.3 IP Assignment with ENET ENCAP Encapsulation
In this case you can have either a static or dynamic IP. For a static IP you must fill in all the IP Address and ENET ENCAP Gateway fields as supplied by your ISP. However for a dynamic IP, the ZyXEL Device acts as a DHCP client on the WAN port and so the IP Address and ENET ENCAP Gateway fields are not applicable (N/A) as the DHCP server
assigns them to the ZyXEL Device.

7.1.5 Nailed-Up Connection (PPP)

A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand. The ZyXEL Device does two things when you specify a nailed-up connection. The first is that idle timeout is disabled. The second is that the ZyXEL Device will try to bring up the connection when turned on and whenever the connection is down. A nailed-up connection can be very expensive for obvious reasons.
Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you need a constant connection and the cost is of no concern

7.1.6 NAT

NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet, for example, the source address of an outgoing packet, used within one network to a different IP address known within another network.
Chapter 7 WAN Setup 91
Page 92
P-2608HWL-Dx Series User’s Guide

7.2 Metric

The metric represents the "cost of transmission". A router determines the best route for transmission by choosing a path with the lowest "cost". RIP routing uses hop count as the measurement of cost, with a minimum of "1" for directly connected networks. The number must be between "1" and "15"; a number greater than "15" means the link is down. The smaller the number, the lower the "cost".
The metric sets the priority for the ZyXEL Device’s routes to the Internet. If any two of the default routes have the same metric, the ZyXEL Device uses the following pre-defined priorities:
• Normal route: designated by the ISP (see Section 7.5 on page 94)
• Traffic-redirect route (see Section 7.7 on page 102)
• WAN-backup route, also called dial-backup (see Section 7.8 on page 103)
For example, if the normal route has a metric of "1" and the traffic-redirect route has a metric of "2" and dial-backup route has a metric of "3", then the normal route acts as the primary default route. If the normal route fails to connect to the Internet, the ZyXEL Device tries the traffic-redirect route next. In the same manner, the ZyXEL Device uses the dial-backup route if the traffic-redirect route also fails.
If you want the dial-backup route to take first priority over the traffic-redirect route or even the normal route, all you need to do is set the dial-backup route’s metric to "1" and the others to "2" (or greater).
IP Policy Routing overrides the default routing behavior and takes priority over all of the routes mentioned above.

7.3 Traffic Shaping

Traffic Shaping is an agreement between the carrier and the subscriber to regulate the average rate and fluctuations of data transmission over an ATM network. This agreement helps eliminate congestion, which is important for transmission of real time data such as audio and video connections.
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of 832Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on the line speed.
Sustained Cell Rate (SCR) is the mean cell rate of each bursty traffic source. It specifies the maximum average rate at which cells can be sent over the virtual connection. SCR may not be greater than the PCR.
92 Chapter 7 WAN Setup
Page 93
P-2608HWL-Dx Series User’s Guide
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more cells (up to the MBS) can be sent at the PCR again.
If the PCR, SCR or MBS is set to the default of "0", the system will assign a maximum value that correlates to your upstream line rate.
The following figure illustrates the relationship between PCR, SCR and MBS.

These are the basic ATM traffic classes defined by the ATM Forum Traffic Management 4.0 Specification.
7.3.1.1 Constant Bit Rate (CBR)
Constant Bit Rate (CBR) provides fixed bandwidth that is always available even if no data is being sent. CBR traffic is generally time-sensitive (doesn't tolerate delay). CBR is used for connections that continuously require a specific amount of bandwidth. A PCR is specified and if traffic exceeds this rate, cells may be dropped. Examples of connections that need CBR would be high-resolution video and voice.
7.3.1.2 Variable Bit Rate (VBR)
The Variable Bit Rate (VBR) ATM traffic class is used with bursty connections. Connections that use the Variable Bit Rate (VBR) traffic class can be grouped into real time (VBR-RT) or non-real time (VBR-nRT) connections.
The VBR-RT (real-time Variable Bit Rate) type is used with bursty connections that require closely controlled delay and delay variation. It also provides a fixed amount of bandwidth (a PCR is specified) but is only available when data is being sent. An example of an VBR-RT connection would be video conferencing. Video conferencing requires real-time data transfers and the bandwidth requirement varies in proportion to the video image's changing dynamics.

P-2608HWL-Dx Series User’s Guide
The VBR-nRT (non real-time Variable Bit Rate) type is used with bursty connections that do not require closely controlled delay and delay variation. It is commonly used for "bursty" traffic typical on LANs. PCR and MBS define the burst levels, SCR defines the minimum level. An example of an VBR-nRT connection would be non-time sensitive data file transfers.
7.3.1.3 Unspecified Bit Rate (UBR)
The Unspecified Bit Rate (UBR) ATM traffic class is for bursty data transfers. However, UBR doesn't guarantee any bandwidth and only delivers traffic when the network has spare bandwidth. An example application is background file transfer.

7.4 Zero Configuration Internet Access

Once you turn on and connect the ZyXEL Device to a telephone jack, it automatically detects the Internet connection settings (such as the VCI/VPI numbers and the encapsulation method) from the ISP and makes the necessary configuration changes. In cases where additional account information (such as an Internet account user name and password) is required or the ZyXEL Device cannot connect to the ISP, you will be redirected to web screen(s) for information input or troubleshooting.
Zero configuration for Internet access is disabled when
• the ZyXEL Device is in bridge mode
• you set the ZyXEL Device to use a static (fixed) WAN IP address.

7.5 Internet Access Setup

To change your ZyXEL Device’s WAN remote node settings, click Network > WAN > Internet Access Setup. The screen differs by the encapsulation.

A static IP address is a fixed IP that your ISP gives you. A dynamic IP address is not fixed; the ISP assigns you a different one each time you connect to the Internet.
Select Obtain an IP Address Automatically if you have a dynamic IP address; otherwise select Static IP Address and type your ISP assigned IP address in the IP Address field below.
Enter a subnet mask in dotted decimal notation. Refer to the appendix to calculate a subnet mask If you are implementing
subnetting.
You must specify a gateway IP address (supplied by your ISP) when you select ENET ENCAP in the Encapsulation field
Select Obtained From ISP if your ISP dynamically assigns DNS server information (and the ZyXEL Device's WAN IP address).
Select User-Defined if you have the IP address of a DNS server. Enter the DNS server's IP address in the field to the right. If you chose User-Defined, but leave the IP address set to 0.0.0.0, User-Defined changes to None after you click Apply. If you set a second choice to User-Defined, and enter the same IP address, the second User-Defined changes to None after you click Apply.
Select DNS Relay to have the ZyXEL Device act as a DNS proxy only when the ISP uses IPCP DNS server extensions. The ZyXEL Device's LAN IP address displays in the field to the right (read-only). The ZyXEL Device tells the DHCP clients on the LAN that the ZyXEL Device itself is the DNS server. When a computer on the LAN sends a DNS query to the ZyXEL Device, the ZyXEL Device forwards the query to the real DNS server learned through IPCP and relays the response back to the computer. You can only select DNS Relay for one of the three servers; if you select DNS Relay for a second or third DNS server, that choice changes to None after you click Apply.
Select None if you do not want to configure DNS servers. You must have another DNS server on your LAN, or else the computers must have their DNS server addresses manually configured. If you do not configure a DNS server, you must know the IP address of a computer in order to access it.
Select Nailed-Up Connection when you want your connection up all the time. The ZyXEL Device will try to bring up the connection automatically if it is disconnected.
