HPNA LAN

To eliminate the need to install network wiring, the Motorola SBG1000 Wireless Cable Modem Gateway provides

a Home Phoneline Network Alliance (HPNA or HomePNA) connection. HPNA networks use existing telephone

lines to connect the computers without interfering with telephone voice service, DSL, ISDN, modems, or fax

machines. HPNA networks can extend up to 300 meters (1000 feet).

Sample HPNA network connections

Each computer requires an HPNA adapter to connect to the HPNA network. HPNA adapters (sold elsewhere) are

available for PCI or USB. After installing the HPNA adapter, you must install HPNA driver software on the

computer following the instructions provided with the HPNA adapter.

HPNA 2.0 supports 10 Mbps data transfer similar to Ethernet 10Base-T.

If there is more than one telephone line, you must make all HPNA connections to the same line. You can connect

a telephone to the top HPNA port on the SBG1000 (see “Front Panel” on page 6).

IEEE 802.11b Wireless LAN

Wireless communication occurs over radio waves rather than a wire. Like a cordless telephone, a wireless LAN

uses radio signals instead of wires to exchange data. A wireless network eliminates the need for expensive and

intrusive wiring to connect computers throughout the home or office. Mobile users can remain connected to the

network even when carrying their laptop to different locations in the home or office.

Each computer on a wireless LAN requires an adapter described in “Optional Accessories” on page 4:

•For wireless laptops connections, use a Motorola PCC11b Wireless Card in the PCMCIA slot.

•For wireless desktop connections, use a Motororal USB11b Wireless Adapter to connect your PC USB port.

Sample wireless network connections

To set up the SBG, on a computer wired to the SBG over Ethernet or USB, perform the procedures in “Setting Up

the Wireless LAN” on page 67.

To set up each wireless client (station):

1Insert the PCC11b and USB11b Wireless Adapter CD-ROM in the CD-ROM drive on the client.

2Install the device software from the CD.

3Connect the Motorola PCC11b wireless card or USB11b wireless adapter following the instructions supplied

with the card or adapter

Security

The Motorola SBG1000 Wireless Cable Modem Gateway provides:

•A firewall to protect the SBG LAN from undesired attacks over the Internet

•Security measures to prevent eavesdropping of wireless data

Network Address Translation (NAT) provides some security because the IP addresses of SBG LAN computers are

not visible on the Internet.

The logical network diagram does not necessarily correspond to the network cabling. A full discussion of network

security is beyond the scope of this document.

SBG1000 security measures shown in a logical network diagram

Firewall

The SBG1000 firewall protects the SBG LAN from undesired attacks and other intrusions from the Internet. It

provides an advanced integrated stateful-inspection firewall supporting intrusion detection, session tracking, and

denial-of-service attack prevention. The firewall:

•Maintains state data for every TCP/IP session on the OSI network and transport layers

•Monitors all incoming and outgoing packets, applies the firewall policy to each one, and screens for improper

packets and intrusion attempts

•Provides comprehensive logging for all:

— User authentications

— Rejected internal and external connection requests

— Session creation and termination

— Outside attacks (intrusion detection)

You can configure the firewall filters to set rules for port usage and to block specific IP domains and networks. For

information about choosing a default firewall policy, see “Setting the Firewall Policy” on page 36.

DMZ

A de-militarized zone (DMZ) is one or more computers logically located outside the firewall between an SBG LAN

and the Internet. A DMZ prevents direct access by outside users to private data. You can use a DMZ to set up a

web server without exposing confidential data on your network. A DMZ is also useful for gamers that have a

problem running a computer game’s protocol through a firewall. DMZ provides the gamer a way to expose a single

host directly to the Internet and thus overcome any firewall issues.

Wireless Security

To prevent unauthorized eavesdropping of data transmitted over the wireless LAN, you must enable wireless

security. The default Open authentication setting provides no security for transmitted data.

You can encrypt data transmitted over the IEEE 802.11b wireless interface by configuring a WEP key on the

Motorola SBG1000 Wireless Cable Modem Gateway and wireless LAN clients (stations).

You can also define a MAC access control list to restrict wireless LAN access to specified clients based on the

client MAC address.

If you enable closed network operation, the network name (ESSID) is not transmitted in the IEEE 802.11b beacon

frame. This provides additional network protection because only IEEE 802.11b stations that are configured with

your network name can associate with the SBG. Closed network operation is not part of the IEEE 802.11b

standard

For information about configuring a WEP key, see “Configuring Basic Wireless LAN Security” on page 69.

Virtual Private Networks

The SBG1000 allows multiple tunnel VPN pass-through operation to securely connect remote computers over the

Internet through the SBG1000. The SBG1000:

•Is compatible with Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP)

•Is fully interoperable with any IPSec client or gateway and ANX certified IPSec stacks

Firewall > POLICY — basic Page

Use this page to select a predefined firewall policy for all packets processed by the SBG firewall, as described in

“Setting the Firewall Policy” on page 36. Advanced users only can create a custom policy on the Firewall >

POLICY — advanced Page (see page 39). The FIREWALL POLICY setting None disables the firewall and

provides no security. We do not recommend this setting.

The predefined policies provide outbound Internet access for computers on the SBG LAN.

The SBG firewall uses stateful inspection to allow inbound responses when there already is an outbound session

running corresponding to the data flow. For example, if you use a web browser, outbound HTTP connections are

permitted on port 80. Inbound responses from the Internet are allowed because an outbound session is

established. When required, the SBG firewall can be configured to allow inbound packets without first

establishing an outbound session.

wireless LAN without changing its default settings. This section describes:

•Configuring a Unique Wireless Network Name (see page 68)

•Configuring Basic Wireless LAN Security (see page 69)

•Configuring Wireless Clients (see page 70)

•Wireless Pages in the SBG Setup Program (see page 70)

Caution!

The default Wired Equivalent Privacy (WEP) Authentication setting Disable WEP provides no

security for wireless data. After the wireless LAN is operational, be sure to configure WEP as

described in “Configuring Basic Wireless LAN Security” on page 69.

Configuring Basic Wireless LAN Security

To enable WEP and set the key on the SBG1000:

1On the SBG Setup Program left frame, click Wireless.

2Click the SECURITY tab to display the Wireless > SECURITY — basic screen:

3Set the following:

4If necessary, click Reset Wireless Defaults to reset the wireless defaults.

5Click Save Changes to save your changes.

Caution!

The default settings provide no security for wireless data. After the wireless LAN is operational, be sure

to enable Shared Key Authentication and Wired Equivalent Privacy (WEP) encryption. You must

configure the same WEP key on the SBG1000 access point and all wireless clients (stations).

Authentication Sets whether shared key authentication is enabled to provide data privacy on the wireless LAN:

•Open System — Any wireless LAN client can transmit data to any other client without

authentication. Open authentication provides no security for transmitted data.

•Shared Key — All data transmitted over the wireless LAN is encrypted. The SBG authenticates

and transfers data to and from all clients having shared key authentication enabled and an

identical WEP key.

For optimal security, we recommend changing the WEP keys frequently. The default is Open

System.

Encryption Use a WEP key length that is compatible with your wireless client adapters. Choose one of:

•Enable 64-Bit — Use only if you have wireless clients that do not support 128-bit encryption

•Enable 128-Bit — The recommended setting for stronger encryption; supported by the Motorola

PCC11b wireless card, USB11b wireless adapter, and most current wireless adapters

•Disable WEP — Recommended during network setup only

Key 1 to Key 4 Sets the active WEP key. You can enter up to four 64-bit or 128-bit WEP keys containing the

non-case-sensitive hexadecimal characters 0 to 9 and A to F. Only one key can be active:

•For 64-bit encryption, the key must be 10 characters long.

•For 128-bit encryption, the key must be 26 characters long.

Configuring Wireless Clients

For each wireless client computer (station), install the wireless client card or adapter — such as a Motorola

PCC11b wireless card or Motorola USB11b wireless adapter — following the instructions supplied with the card or

adapter.

Configure the card or adapter to obtain an IP address automatically. The Motorola PCC11b wireless card and

Motorola USB11b wireless adapter are supplied with a client configuration program called Wireless Client Manger,

which is installed in the Windows Startup group.

If Wireless Client Manager is running, the icon is displayed on the Windows task bar. Double-click the icon to

launch the utility.

To distinguish it from other nearby IEEE 802.11b wireless LANs, each wireless LAN is identified by a unique

network name (also known as a network identifier or ESSID). When prompted for the network identifier, network

name, or ESSID, type the name set in the ESSID field on the Wireless > NETWORK window in the SBG Setup

Program. For more information, see “Configuring a Unique Wireless Network Name” on page 68.

After you specify the network name, the wireless card or adapter automatically scans for an IEEE 802.11b access

point such as the SBG1000 and the proper channel and data rate.

If shared key authentication is enabled and a WEP key is set on the SBG1000 as described in “Configuring Basic

Wireless LAN Security” on page 69, you must enter the same WEP key on the wireless client. The SBG1000

cannot authenticate a client if:

•Shared key authentication is enabled on the SBG1000 but not on the client

•The client WEP key does not match the SBG1000 WEP key

After you correctly set the network name and WEP key on the client computer, you should be able to use it to surf

the Internet.

Wireless Pages in the SBG Setup Program

Use the Wireless pages to control and monitor the wireless interface:

•Wireless > STATUS Page (see page 71)

•Wireless > NETWORK Page (see page 72)

•Wireless > SECURITY — basic Page (see page 73)

•Wireless > SECURITY — advanced Page (see page 74)

•Wireless > STATISTICS page (see page 75)

You can use the Motorola SBG1000 Wireless Cable Modem Gateway to operate an IEEE 802.11b wireless LAN

without changing its default settings.

Wireless > NETWORK page fields

Field Description

Enable Wireless

Interface Check this box to enable the wireless interface.

ESSID Sets a unique identifier to associate wireless clients with the SBG access point. This

distinguishes between multiple wireless LANs in the same area. All clients on wireless LAN

must have the same Network Name as the access point. It can be any alphanumeric,

case-sensitive string up to 32 characters. The default is “Motorola.” We strongly recommend

not using the default.

Channel Sets the wireless radio channel. You can change the channel if you encounter interference on

the default channel. The default is 1 (one), except in countries where the first channel

permitted for IEEE 802.11b wireless operation is not one.

Basic Rate Sets the wireless data transmission rates that all wireless LAN clients must be able to receive:

•1, 2 Mbps. The SBG1000 attempts to transmit at 2 Mbps. Use this setting if the wireless

LAN has only legacy IEEE 802.11b clients.

•1, 2, 5.5, and 11 Mbps. The SBG1000 attempts to transmit at 11 Mbps. If there are

obstacles or interference, it automatically steps down to the highest rate that allows

transmission. Use this setting if the wireless LAN has fully-compliant IEEE 802.11b clients.

The default is 1, 2, 5.5, 11 Mbps.

Transmit Power Sets the transmit power on the SBG1000 wireless access point — 1, 2, 5, 10, 25, 50, or 100

mW. The default is 32 mW. Transmit power control is an optional IEEE 802.11b feature.

RTS Threshold The Request To Send Threshold sets the packet size at which the access point issues an RTS

before sending the packet. A low RTS can help when many clients are associated with the

SBG1000 or when the clients are far apart and can detect the SBG1000 but not each other.

The value can be 0 to 2347 bytes. The default is 2347.

Fragmentation

Threshold Sets the size at which packets are fragmented (sent as several packets instead of as one

packet). A low Fragmentation Threshold can help when communication is poor or when there

is a significant interference.

The default is 2346. The value can be 256 to 2346 bytes.

Enable Short Preamble Short preamble can improve throughput when the SBG1000 access point and associated

clients operate at 2, 5.5, or 11 Mbps. If you enable short preamble, be sure all wireless clients

also support short preamble. Short preamble is an optional IEEE 802.11b feature that is useful

if maximum throughput is important and interoperability with legacy IEEE 802.11b equipment is

not required. The default is Disabled.

CAUTION!

The default Authentication setting of Disable WEP provides no security for transmitted data.

Protocol Choose Standard if the printer uses a communication protocol that supports sending and receiving

ASCII data. The Standard protocol is typically supported on devices using RS-232 and centronics

channels. The default is ASCII.

Choose Binary Communication Protocol (BCP) if the printer can send and receive binary data. BCP

is used by some devices for flow control, status request, abort job, and end of file functions. BCP

can provide a significant performance advantage over ASCII printing on serial and parallel ports.

Choose Tagged Binary Communication Protocol (TBCP) for a printer containing a

language-independent feature to determine which language interprets a print job. TBCP is typically

supported by PJL printers.

To determine the protocol a printer supports, see the documentation provided with the printer.

Frequently-Asked Questions

Here are answers to questions our customers frequently ask:

Q What is high-speed cable Internet access?

A Cable Internet access uses cable television wires instead of telephone lines to connect to the Internet. It is

extremely fast and does not tie up telephone lines for incoming or outgoing calls and faxes.

Q How fast is the Motorola SBG1000 Wireless Cable Modem Gateway?

A Cable modems offer Internet access at speeds up to 100 times faster than a traditional phone modem. You

can experience speeds of over 1,000 Kbps. Due to network condition such as traffic volume and the speed of

the sites you visit, actual speed may vary. Many network and other factors can affect download speeds.

Q How many users can one SBG support?

A A single SBG can support up to 245 users, each assigned a unique IP address, on a class C network.

Q What is Network Address Translation?

A NAT is a technique to translate private IP addresses on your LAN to a single IP address assigned by your

cable service provider that is that is visible to outside users on the Internet.

Q What is IEEE_802.11b?

A IEEE 802.11b is the IEEE wireless network standard.

Q What type of firewall is provided on the SBG1000?

A The SBG1000 provides a stateful-inspection firewall.

Q What wireless security measures are provided on the SBG1000?

A To protect data transmitted over wireless connections, the SBG1000 supports WEP encryption and MAC

access control lists. For information, see “Setting Up the Wireless LAN” on page 67.

Q Why is there no Standby button?

A As a security measure, current Motorola SURFboard cable modems provide a Standby button to temporarily

suspend the Internet connection. Because the SBG firewall provides high security levels while connected, the

Standby button is not required.

Q Can I still watch cable TV while using my Motorola SBG1000 Wireless Cable Modem Gateway?

A Yes, your cable TV line can carry the TV signal while you send and receive information on the Internet.

Q What are CableLabs Certified, DOCSIS, and Euro-DOCSIS?

A CableLabs Certified, DOCSIS, and Euro-DOCSIS are the industry standards for high-speed data distribution

over cable television system networks. They are intended to ensure that all compliant SBGs interface with all

compliant cable systems. Your SBG1000 is DOCSIS or Euro-DOCSIS certified.

Q If I have an SBG1000, can I still use my old 28.8 Kbps or 56 Kbps modem?

A Yes you can. However, once you’ve experienced the speed of cable Internet access, you’ll never again want

to wait for traditional dial-up services.

Gauge (AWG) A standard system used to designate the size of electrical conductors; gauge numbers are inverse to

size.

ANSI The American National Standards Institute is a non-profit, independent organization supported by

trade organizations, industry, and professional societies for standards development in the United

States. This organization defined ASCII and represents the United States to the International

Organization for Standardization.

ANX Automotive Network Exchange

ARP Address Resolution Protocol broadcasts a datagram to obtain a response containing a MAC address

corresponding to the host IP address. When it is first connected to the network, a client sends an ARP

message. The SBG1000 responds with a message containing its MAC address. Subsequently, data

sent by the computer uses the SBG1000 MAC address as its destination.

ASCII The American Standard Code for Information Interchange refers to alphanumeric data for processing

and communication compatibility among various devices; normally used for asynchronous

transmission.

asynchronous

timing The SBG1000 uses synchronous timing for upstream data transmissions. The CMTS broadcasts

messages that bandwidth is available. The SBG1000 reserves data bytes requiring x-number of

mini-slots. The CMTS replies that it can receive data at a specified time (synchronized). At the

specified time, the SBG transmits the x-number of data bytes.

attenuation The difference between transmitted and received power resulting from loss through equipment,

transmission lines, or other devices; usually expressed in decibels.

authentication A process where the CMTS verifies that access is authorized, using a password, trusted IP address,

or serial number.

authorization Part of the process between a CMTS and the cable modem or gateway to enable Baseline Privacy.

auto-MDIX Automatic medium-dependent interface crossover detects and corrects cabling errors by automatically

reversing the send and receive pins on any port. It enables the use of straight-through wiring between

the SBG Ethernet ports and any computer, printer, or hub.

bandwidth The transmission capacity of a medium in terms of a range of frequencies. Greater bandwidth

indicates the ability to transmit more data over a given period of time.

Baseline

Privacy An optional feature that encrypts data between the CMTS and the cable modem or gateway.

Protection of service is provided by ensuring that a cable modem or gateway, uniquely identified by its

MAC address, can only obtain keys for services it is authorized to access.

baud The analog signaling rate. For complex modulation modes, the digital bit rate is encoded in multiple

bits per baud, for example, 64 QAM encodes 6 bits per baud and 16 QAM encodes 4 bits per baud.

BCP Binary Communication Protocol

BER The bit error rate is the ratio of the number of erroneous bits or characters received from some fixed

number of bits transmitted.

binary A numbering system that uses two digits, 0 and 1.

bit rate The number of bits (digital 0s and 1s) transmitted per second in a communications channel. It is

usually measured in bits per second bps.

BPKM Baseline Protocol Key Management encrypts data flows between a cable modem or gateway and the

CMTS. The encryption occurs after the cable modem or gateway registers to ensure data privacy

across the RF network.

bps bits per second

bridge An OSI layer 2 networking device that connects two LANs using similar protocols. It filters frames

based on the MAC address to reduce the amount of traffic. A bridge can be placed between two

groups of hosts that communicate a lot together, but not so much with the hosts in the other group.

The bridge examines the destination of each packet to determine whether to transmit it to the other

side. See also switch.

broadband High bandwidth network technology that multiplexes multiple, independent carriers to carry voice,

video, data, and other interactive services over a single cable. A communications medium that can

transmit a relatively large amount of data in a given time period. A frequently used synonym for cable

TV that can describe any technology capable of delivering multiple channels and services.

datagram In RFC 1594, a datagram is defined as “a self-contained, independent entity of data carrying sufficient

information to be routed from the source to the destination computer without reliance on earlier

exchanges between this source and destination computer and the transporting network.” For the most

part, it has been replaced by the term packet.

default route The route by which packets are forwarded when other routes in the routing table do not apply.

dB decibel

dBc Signal level expressed in dB relative to the unmodulated carrier level desired.

DBm A unit of measurement referenced to one milliwatt across specified impedance. 0dBm = 1 milliwatt

across 75 ohms.

dBmV Signal level expressed in dB as the ratio of the signal power in a 75-ohm system to a reference power

when 1 mV is across 75 ohms.

demodulation An operation to restore a previously modulated wave and separate the multiple signals that were

combined and modulated on a subcarrier.

DHCP A Dynamic Host Configuration Protocol server dynamically assigns IP addresses to client hosts on an

IP network. DHCP eliminates the need to manually assign static IP addresses by “leasing” an

IP address and subnet mask to each client. It enables the automatic reuse of unused IP addresses:

The SBG is simultaneously a DHCP client and a DHCP server.

•A DHCP server at the cable system headend assigns a public IP address to the SBG1000 and

optionally to clients on the SBG LAN.

•The SBG contains a built-in DHCP server that assigns private IP addresses to clients.

distortion An undesired change in signal waveform within a transmission medium. A nonlinear reproduction of

the input waveform.

diversity

antennas Two identical antennas located a small distance apart to reduce multipath distortion and improve

wireless reception. Properly placed diversity antennas improve SBG wireless reception.

DNS The Domain Name System is the Internet system for converting domain names to IP addresses. A

DNS server contains a table matching domain names such as Internetname.com to IP addresses

such as 192.169.9.1. When you access the world-wide web, a DNS server translates the URL

displayed on the browser to the destination website IP address. The DNS lookup table is a distributed

Internet database; no one DNS server lists all domain name to IP address matches.

DOCSIS The CableLabs Data-Over-Cable Service Interface Specification defines interface standards for cable

modems, gateways, and supporting equipment to deliver data between an HFC network and a

computer systems or television sets. To emphasize its use as a cable modem standard, DOCSIS is

now called CableLabs Certified Cable Modems. Euro-DOCSIS is DOCSIS adapted for use in Europe.

domain name A unique name, such as motorola.com, that maps to an IP address. Domain names are typically much

easier to remember than are IP addresses.

dotted-decimal

format Method of representing an IP address or subnet mask using four decimal numbers called octets. Each

octet represents eight bits.

In a class C IP address, the octets are “network.network.network.host.” The first three octets together

represent the network address and the final octet is the host address. In the SBG LAN default

configuration, 192.168.100 represents the network address. In the final octet, the host address can be

from 2 to 254.

download To copy a file from one computer to another. You can use the Internet to download files from a server

to a computer. A DOCSIS or Euro-DOCSIS cable modem or gateway downloads its configuration file

from a TFTP server during start-up.

downstream In a cable data network, the direction of data received by the computer from the Internet.

IP address A unique 32-bit value that identifies each host on a TCP/IP network. TCP/IP networks route messages

based on the destination IP address. An IP address has two parts:

•The network address is assigned by IANA.

•The SBG network administrator assigns a host address to each host connected to the SBG1000,

automatically using its DHCP server or as a static IP address.

For a class C network, the first 24 bits are the network address and the final 8 bits are the host

address; in dotted-decimal format it appears “network.network.network.host.”

L2F Layer 2 Forwarding is an OSI layer 2 protocol that establishes a secure tunnel across the Internet to

create a virtual PPP connection between the user and the enterprise network. L2F is the most

established and stable layer 2 tunneling protocol.

L2TP Layer 2 Tunnel Protocol is a PPP extension that enables ISPs to operate VPNs. L2TP merges the

best features of the PPTP and L2F. L2TP is the emerging IETF standard.

LAC An L2TP access concentrator is a device to which the client directly connects through which PPP

frames are tunneled to the LNS. The LAC need only implement the media over which L2TP operates

to transmit traffic to one or more LNSs. The LAC may tunnel any protocol carried within PPP. The LAC

initiates incoming calls and receives outgoing calls. A LAC is analogous to an L2F NAS.

LAN A local area network provides a full-time, high-bandwidth connection over a limited area, such as a

building or campus. Ethernet is the most widely used LAN standard.

LNS An L2TP network server is a termination point for L2TP tunnels where PPP frames are processed and

passed to higher layer protocols. An LNS can operate on any platform that terminates PPP. The LNS

handles the server side of the L2TP protocol. L2TP relies only on the single media over which L2TP

tunnels arrive. The LNS can have a single LAN or WAN interface but can terminate calls arriving at

any of the LACs full range of PPP interfaces (asynchronous, synchronous, ISDN, V.120, etc.). The

LNS initiates outgoing calls and receives incoming calls. An LNS is analogous to a home gateway in

QAM Quadrature Amplitude Modulation uses amplitude and phase modulation to encode multiple bits of

data in one signaling element. QAM achieves faster data transfer than amplitude or phase modulation

alone, but the signal is more prone to errors caused by noise. QAM requires a transmission circuit with

a higher CNR than alternate modulation formats such as QPSK. Two types of QAM are:

•16 QAM encodes four bits per symbol as one of 16 possible amplitude and phase combinations.

•64 QAM encodes six bits per symbol as one of 64 possible amplitude and phase combinations.

QPSK Quadrature Phase Shift Key (QPSK) modulation sends two bits of information per symbol period with

one symbol 90 degrees out of phase with other symbols. The four constellation points represented by

the coordinates (0,0 - 0,1 - 1,0 - 1,1) represent the four possible combinations.
