Tips for Reading User’s Guides On-Screen
When reading a ZyXEL User’s Guide On-Screen, keep the following in mind:
• If you don’t already have the latest version of Adobe Reader, you can download
it from http://www.adobe.com.
• Use the PDF’s bookmarks to quickly navigate to the areas that interest you.
Adobe Reader’s bookmarks pane opens by default in all ZyXEL User’s Guide
PDFs.
• If you know the page number or know vaguely which page-range you want to
view, you can enter a number in the toolbar in Reader, then press [ENTER] to
jump directly to that page.
• Type [CTRL]+[F] to open the Adobe Reader search utility and enter a word or
phrase. This can help you quickly pinpoint the information you require. You can
also enter text directly into the toolbar in Reader.
• To quickly move around within a page, press the [SPACE] bar. This turns your
cursor into a “hand” with which you can grab the page and move i t around freely
on your screen.
• Embedded hyperlinks are actually cross-references to related text. Click them to
jump to the corresponding section of the User’s Guide PDF.

CHAPTER 1
Getting To Know Your P-793H v2
This chapter introduces the main features and applications of your P-793H v2.
1.1 Overview
The P-793H v2 is a secure G.SHDSL.bis bonded broadway gateway that provides
high-speed LAN-to-LAN connection and Internet access over the your telephone.
It supports symmetrical multi-rate data transmission speed that adjusts the data
rate automatically according to the quality of the wire connection.
You can set up your P-793H v2 for high-speed Internet access or for high-speed
point-to-point or point-to-2 points connections with other SHDSL models. The P793H v2 can be used for either IP routing or bridging depending on your network
configuration. As a router, the P-793H v2 provides features such as firewall,
content filtering and bandwidth management. As a bridge, the P-793H v2
minimizes the configuration changes you have to make in your existing network.
See Appendix A on page 417 for a complete list of features you can configure on
your P-793H v2.
1.1.1 High-speed Internet Access with G.SHDSL
The P-793H v2 provides high-speed G.SHDSL Internet access. The G.SHDSL
(Single-pair High-speed Digital Subscriber Line) is a symmetrical, bi-directional
DSL service that uses your telephone line to provide data rates up to 2. 3 M b it s /
sec. (The “G.” in “G.SHDSL” is defined by the G.991.2 ITU (International
P-793H v2 User’s Guide

Chapter 1 Getting To Know Your P-793H v2
Telecommunication Union) state-of-the-art industry standard). Unlike ADSL or
VDSL, G.SHDSL.bis supports the same high speed for transmission and receiving.
Figure 1 High-speed Internet Access with Your P-793H v2
For Internet access, connect the DSL port to the phone po rt. Then, connect your
computers or servers to the LAN ports for shared Internet access. (See the Quick
Start Guide for detailed instructions about hardware connections.) Next, set up
the P-793H v2 as a router or as a bridge, depending on the desired config uration.

Note: See Chapter 5 on page 67 for more information on setting up point-to -point and
point-to-2points connections.
1.2 Ways to Manage the P-793H v2
Use any of the following methods to manage the P-793H v2.
• Web Configurator. This is recommended for everyday management of the P793H v2 using a (supported) web browser. See Chapter 2 on page 43.
• Command Line Interface. Line commands are mostly used for troubleshooting
by service engineers. See Appendix H on page 471.
• SMT. System Management Terminal is a text-based configuration menu th at you
can use to configure your device. See Chapter 23 on page 301.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/
restore. See Chapter 17 on page 243.
• SNMP. The device can be monitored and/or managed by an SNMP manager. See
Chapter 17 on page 243.
• TR-069. This is a standard that defines how your P-793H v2 can be managed by
a management server. See Chapter 17 on page 243.

1.3 Good Habits for Managing the P-793H v2
Do the following things regularly to make the P-793H v2 more secure and to
manage the P-793H v2 more effectively.
• Change the password. Use a password that’s not easy to guess and that consists
of different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it).
Restoring an earlier working configuration may be useful if the device becomes
unstable or even crashes. If you forget y our password, you will hav e to reset the
P-793H v2 to its factory default settings. If you backed up an earlier
configuration file, you would not ha ve to totally re-configure the P-793H v2. You
could simply restore your last configuration.
1.4 LEDs
The following figure shows the LEDs.

Note: For Internet access setup or point-to-point connections, the DSL1 and DSL2
LEDs indicate the status of a single connection (act as one LED). For pointto-2point connections, the DSL1 and DSL2 LEDs indicate the status of
connection 1 and connection 2 respectively.
INTERNET Green On The Internet connection is up, and the P-793H v2 has
an IP address. (If the P-793H v2 uses RFC 1483 in
bridge mode, this light does not turn on, but it does
blink when the P-793H v2 is sending/receiving data.)
Blinking The P-793H v2 is sending/receiving data.
Red On The P-793H v2 tried to get an IP address, but an
error occurred.
Off The Internet connection is down.
1.5 The RESET Button
If you forget your password or cannot access the web configurator, you will need
to use the RESET button at the back of the device to reload the factory-default
configuration file. This means that you will lose all configurations that you had
previously and the password will be reset to “1234”.
1.5.1 Using the RESET Button
1 Make sure the POWER LED is on (not blinking).
2 To set the device back to the factory default settings, press the RESET button for
ten seconds or until the POWER LED begins to blink and then release it. When the
POWER LED begins to blink, the defaults have been restored and the device
restarts.

WAN Setup
6.1 Overview
This chapter describes how to configure WAN settings from the WAN screens. Use
these screens to configure your P-793H v2 for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another
network or the Internet. It connects your private networks (such as a LAN (Local
Area Network) and other networks, so that a computer in one location can
communicate with computers in other locations.
Figure 27 LAN and WAN
LAN
WAN
6.1.1 What You Can Do in the WAN Screens
•Use the Internet Access Setup screen (Section 6.2 on page 78) to configure
the WAN settings on the P-793H v2 for Internet access.
•Use the More Connections screen (Section 6.3 on page 86) to set up
additional Internet access connections.
•Use the WAN Backup Setup screen (Section 6.4 on page 92) to set up a
backup gateway that helps forward traffic to its destination when the default
WAN connection is down.

Chapter 6 WAN Setup
6.1.2 What You Need to Know About WAN
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower
layer protocol. To set up a WAN connection to the Internet, you need to use the
same encapsulation method used by your ISP (Internet Service Provider). If your
ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet) or PPPoA,
they should also provide a username and password (and service name) for user
authentication.
WAN IP Address
The WAN IP address is an IP address for the P-793H v2, which makes it accessible
from an outside network. It is used by the P-793H v2 to communicate with other
devices in other networks. It can be static (fixed) or dynamically assigned by the
ISP each time the P-793H v2 tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the
subnet mask and DNS server IP address(es) (and a gateway IP add ress if you use
the Ethernet or ENET ENCAP encapsulation method).
ATM
Asynchronous Transfer Mode (ATM) is a LAN and WAN networking technology that
provides high-speed data transfer. ATM uses fixed-size packets of information
called cells. With A TM, a high QoS (Quality of Service) can be guaranteed. ATM
uses a connection-oriented model and establishes a virtual circuit (VC) between
two endpoints before the actual data exchange begins.
PTM
Packet Transfer Mode (PTM) is packet-oriented and supported by the VDSL2
standard. In PTM, packets are encapsulated directly in the High-level Data Link
Control (HDLC) frames. It is des igned to provide a low-ov erhead, tr ansparent w ay
of transporting packets over DSL links, as an alternative to ATM.
Multicast
76
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1
sender - 1 recipient) or Broadcast (1 sender - everybody on the network).
Multicast delivers IP packets to a group of hosts on the network - not everybody
and not just one.
P-793H v2 User’s Guide
Page 77
IGMP
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a Multicast group - it is not used to carry user data.
There are three versions of IGMP. IGMP version 2 and 3 are improvements over
version 1, but IGMP version 1 and 2 are still in wide use.
Finding Out More
See Section 6.5 on page 93 for technical background information on WAN.
6.1.3 Before You Begin
You need to know your Internet access settings such as encapsulation and W AN IP
address. Get this information from your ISP.

6.5 WAN Technical Reference
This section provides some technical background information about the topics
covered in this chapter.
6.5.1 Encapsulation
Be sure to use the encapsulation method required by your ISP. The P-793H v2
supports the following methods.
P-793H v2 User’s Guide
93
Page 94
Chapter 6 WAN Setup
6.5.1.1 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 Gateway IP Address field in the wizard or WAN screen. You can get this
information from your ISP.
6.5.1.2 PPP over Ethernet
The P-793H v2 supports PPPoE (P oint-to-P oint Protocol ov er Ethernet). PPPoE is an
IETF Draft standard (RFC 2516) specifying how a personal computer (PC) inter acts
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 servic e 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 .
By implementing PPPoE directly on the P-793H v2 (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the P-793H v2 does that part of the task. Furthermore, with NAT, all of the
LANs’ computers will have access.
6.5.1.3 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 P-793H v2
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
Subscriber Line (DSL) Access Multiplexer). Please refer to RFC 2364 for more
information on PPPoA. Refer to RFC 1661 for more information on PPP.
6.5.1.4 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 A TM virtual circuit (LL C-based multiplexing) and the second
94
P-793H v2 User’s Guide
Page 95
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.
6.5.2 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.
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.
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.
Chapter 6 WAN Setup
6.5.3 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.
6.5.4 IP Address Assignment
A static IP is a fixed IP that your ISP gives y ou. A dynamic IP is not fix e d; 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.
IP Assignment with PPPoA or PPPoE Encapsulation
If you have a dynamic IP, then the IP Address and Gateway IP Address 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 Gateway IP Address field.
P-793H v2 User’s Guide
95
Page 96
Chapter 6 WAN Setup
IP Assignment with RFC 1483 Encapsulation
In this case the IP address assignment must be static.
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 Gateway IP Address fields as supplied by your ISP.
However for a dynamic IP, the P-793H v2 acts as a DHCP client on the WAN port
and so the IP Address and Gateway IP Address fields are not applicable (N/A)
as the DHCP server assigns them to the P-793H v2.
6.5.5 Nailed-Up Connection (PPP)
A nailed-up connection is a dial-up line where the connection is always up
regardless of traffic demand. The P-793H v2 does two things when you specify a
nailed-up connection. The first is that idle timeout is disabled. The second is that
the P-793H v2 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 flatrate service or you need a constant connection and the cost is of no concern.
6.5.6 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.
6.6 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".
96
The metric sets the priority for the P-793H v2’s routes to the Internet. If any two
of the default routes have the same metric, the P-793H v2 uses the following predefined priorities:
P-793H v2 User’s Guide
Page 97
• Normal route: designated by the ISP (see Section 6.2 on page 78)
• Traffic-redirect route (see Section 6.7 on page 97)
For example, if the normal route has a of "1" and the traffic-redirect route has a
metric of "2", then the normal route acts as the primary default route. If the
normal route fails to connect to the Internet, the P-793H v2 tries the trafficredirect route next.
If you want the traffic-redirect route route to take priority over the normal route,
all you need to do is set the traffic-redirect route’s metric to "1" and the normal
route to "2".
IP Policy Routing overrides the default routing behavior and takes priority over all
of the routes mentioned above.
6.7 Traffic Redirect
Chapter 6 WAN Setup
Traffic redirect forwards traffic to a backup gateway when the P-793H v2 cannot
connect to the Internet. An example is shown in the figure below.
Figure 35 Traffic Redirect Example
The following network topology allows you to avoid triangle route security issues
when the backup gateway is connected to the LAN. Use IP alias to configure the
LAN into two or three logical networks with the P-793H v2 itself as the gateway for
each LAN network. Put the protected LAN in one subnet (Subnet 1 in the following
figure) and the backup gateway in another subnet (Subnet 2). Configure filters
P-793H v2 User’s Guide
97
Page 98
Chapter 6 WAN Setup
that allow packets from the protected LAN (Subnet 1) to the backup gateway
(Subnet 2).
Figure 36 Traffic Redirect LAN Setup
6.8 Traffic Shaping
T r affic 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.
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.
98
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.
P-793H v2 User’s Guide
Page 99
The following figure illustrates the relationship between PCR, SCR and MBS.
Figure 37 Example of Traffic Shaping
6.8.1 ATM Traffic Classes
These are the basic ATM traffic classes defined by the ATM Forum Traffic
Management 4.0 Specification.
Chapter 6 WAN Setup
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.
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-R T (real-time V ariable Bit Rate) type is used with burst y 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.
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
P-793H v2 User’s Guide
99
Page 100
Chapter 6 WAN Setup
levels, SCR defines the minimum level. An example of an VBR-nRT connection
would be non-time sensitive data file transfers.
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 tr affic when the
network has spare bandwidth. An example application is background file transfer.
