Appendix B: Troubleshooting
This section discusses possible problems and outlines possible solutions.
1. I cannot access the Motorola Cellular Gateway NC800’s web-based Configuration utility.
It is recommended, but not required, that you configure the Motorola Cellular Gateway NC800 via a
computer that is directly connected to the Motorola Cellular Gateway NC800’s LAN interface.
•
•
•
Check that the Motorola Cellular Gateway NC800 is properly installed and is powered ON.
Check that there is a network connection between the Motorola Cellular Gateway NC800 and the
computer that is being used to configure the Motorola Cellular Gateway NC800.
o Check that the computer is connected to the Motorola Cellular Gateway NC800, either directly or
via another network path for example via a hub or a switch.
o Check that the computer’s Ethernet adapter is working correctly.
 Ensure that the drivers for the network adapters are installed correctly.
 Check the status of the network connection. It should say “connected” or indicate the speed
of the connection e.g. 10 Mbps or 100 Mbps.
o Check that the PC’s IP address is in the same range and subnet as that of the Motorola Cellular
Gateway NC800.
o Try to ping the Motorola Cellular Gateway NC800 to make sure that it is responding. Open a
command console window (Go to Start -> Run. Type in cmd (if you are using Windows 98 / ME
type in command). When the console window opens, type in ping 192.168.1.1. If you have
changed the IP address of the Motorola Cellular Gateway NC800 then use that address instead.
The Motorola Cellular Gateway NC800 should respond with four replies.
Check the Security Level set on the Browser. Depending on the browser, a High Security Level might
prevent Javascripts from being executed on the PC. On the browser configuration, set the Internet
Security to Low and ensure that Javascripting is enabled.
A quick way to check a network
connection is to use the ping
command.
Type
in
ping
xxx.xxx.xxx.xxx where xxx is the IP
Address that you want to test. The
command then sends test packets to
the destination address. If there exists a
network connection to the address, you
should see four replies.
Be sure to use the correct IP address.
2. How do I check that my LAN Ethernet adapter is working
correctly?
•
•
Select Control Panel from My Computer. Go to Network
Connections and double-click on the Ethernet Adapter.
If your network card is working correctly:
o The Status will be Connected.
o The Sent and Received byte counter will increase as
data is sent and received via the network adapter.

3. I cannot establish a wireless connection to the Motorola Cellular Gateway NC800.
Please consult the user guide of your computer’s WLAN adaptor when configuring any of the
settings discussed below.
•
•
Check that you are using the same SSID and channel number as the Motorola Cellular Gateway
NC800. If either one is not the same then the wireless data packets will be ignored by the Motorola
Cellular Gateway NC800.
If the Motorola Cellular Gateway NC800 is set to use WEP encryption then ensure that the wireless
adapter on the client is also set accordingly. Make sure the encryption level (i.e. whether a 64-bit or
128-bit key is used) is set to the same level on both the client and the Motorola Cellular Gateway
NC800. Also check that the encryption keys are the same.
4. My wireless LAN connection is being dropped intermittently.
•
•
•
•
Please refer to the Installation Considerations section for more information on how to optimally
position wireless network devices.
Check the antenna orientation on the Motorola Cellular Gateway NC800.
Check to see if other electronic equipment is not interfering with the wireless data transmissions.
Use the laptop or workstation’s signal strength indicator to see what the signal strength is at the current
location. It could be that the signal strength is just too low for a reliable connection. In this case you
need to move the wireless adapter closer to the Motorola Cellular Gateway NC800 for increased signal
strength.
5. The network is configured correctly, but the Motorola Cellular Gateway NC800 is not responding
•
•
Check to see if any of the lights (LEDs) on the Motorola Cellular Gateway NC800 are flickering at all.
If the is no flickering for an extended period of time then you can try to reset the Motorola Cellular
Gateway NC800 by pressing the Reset button at the back of the Motorola Cellular Gateway NC800. Do
not hold the Reset button in, only press it once and release it again. This will reset the Motorola Cellular
Gateway NC800.
6. I do not know the IP address / User name / Password of the Motorola Cellular Gateway NC800
anymore.
In some cases, the IP address / User Name / Password of the Motorola Cellular Gateway NC800 may not be
known anymore, making it impossible to connect to the web-based Configuration Utility.
•
After you have tried all other methods of trouble shooting, you can restore the Motorola Cellular
Gateway NC800’s factory default settings.
o Locate the Reset button on the back of the Motorola Cellular Gateway NC800.
o Press the Reset button and hold it down for 10 seconds.
o Release the Reset button.
o The Motorola Cellular Gateway NC800 will reboot and all the settings will be set according to the
factory default settings.
o You will have to redirect any open web browser to the Motorola Cellular Gateway NC800’s default
IP address: 192.168.1.1, using the default user name (admin) and password (admin).
7. When using DHCP on the LAN interface, the IP address that my computer receives is not correct.
•
•
Ensure that there is no other DHCP server active on the same LAN segment that the Motorola Cellular
Gateway NC800 is located on. If more than one DHCP server is active on your network you could see
that some computers receive IP addresses from the first DHCP server and the rest of the computers
from the next. This will cause major network problems and should be avoided by only having ONE
DHCP server active on a network.
Check that the Motorola Cellular Gateway NC800’s DHCP starting and ending DHCP IP address
ranges are correct.
Motorola Cellular Gateway NC800 User Guide Version 2.0

8. I cannot connect to the Internet via the Motorola Cellular Gateway NC800.
•
•
•
•
If your Cellular Carrier or ISP is using PPP, then check that the WAN-> PPP Config settings are
configured correctly.
Try to ping the WAN Interface port IP address.
Try to ping your ISP’s default Motorola Cellular Gateway NC800 – check to see if the modem’s activity
lights are flickering when you do this.
Try to ping a well-known Internet IP address such as www.motorola.com.
9. I need to access the Motorola Cellular Gateway NC800’s configuration remotely.
To access the Motorola Cellular Gateway NC800’s web-based configuration utility from the Internet you need to:
• Under Gateway-> Login Settings specify a Gateway WAN Port.
• A good value to use is 8080.
• To open the web-based utility, open a browser to http://:8080 where  is the IP address of the
Motorola Cellular Gateway NC800’s WAN Interface.
• You get the WAN Interface IP address from the WAN->IP Settings pages.
• When prompted, type in the same username and password that you would normally use when opening
the web-based configuration utility.
10. I do not see the full 54 Mbps throughput when using the wireless interface.
As with any wireless protocol, 802.11g has overhead associated with it that limits performance. While signaling
data rates of up to 54 Mbps may be achieved, like most shared media (e.g. Ethernet) throughput will be
significantly less.
There are two scenarios for 802.11g performance. In an environment with only 802.11g clients, throughput of up
to 23 Mbps is expected. This performance is equal to that of 802.11a, although 802.11g is usually available over
a greater range - distance - from the Motorola Cellular Gateway NC800. The second scenario is when 802.11b
clients are present. RTS/CTS flow control (a signaling technique used by the 802.11 standard) must be used to
allow 802.11b clients to recognize and establish communications with 802.11g access points. This leads to
delays in transmission and drops peak throughput to about 10 Mbps. 802.11g performance is still well in excess
of the maximum measured speeds of 4-5 Mbps for 802.11b.
The use of RTS/CTS is important because it provides determinism to the wireless network, ensuring a minimum
bandwidth for each user. Like Ethernet, 802.11 LANs normally use a "carrier sense media access" mechanism
to signal transmission without asking for permission from the network. As the network becomes highly loaded,
collisions occur more frequently, and the network can become saturated with packet retransmission attempts
that eventually make it impossible for any data to get through. RTS/CTS provide a more formalized flow-control
mechanism that avoids this problem.
For optimal throughput keep the following in mind:
• Refer to the section on “Installation Considerations” for information on how to optimally
position the Motorola Cellular Gateway NC800.
• Do not connect more than 32 wireless clients to the Motorola Cellular Gateway NC800.
Rather spread the wireless clients over more than one Motorola Cellular Gateway NC800.
• Try to keep the number of 802.11b wireless clients to a minimum. The Motorola Cellular
Gateway NC800 is compatible with 802.11b clients, but this degrades the overall wireless
performance of the network. If at all possible, try to use only 802.11g wireless adapters in
your network.

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 the source and destination computer and the
transporting network. For the most part, it has been replaced by the term packet.
Default
gateway
The gateway used to forward all traffic that is not addressed to a station within the local
subnet.
Default route
The route by which packets are forwarded when other routes in the routing table do not
apply.
DHCP
Dynamic Host Configuration Protocol - A protocol that lets network administrators manage
centrally and automate the assignment of Internet Protocol (IP) addresses in an
organization’s network. Each machine that can connect to the Internet needs a unique IP
address. When an organization sets up its computer users with a connection to the Internet,
an IP address must be assigned to each machine. Without DHCP, the IP address must be
entered manually at each computer and if computers move to another location in another
part of the network, a new IP address must be entered. DHCP lets a network administrator
supervise and distribute IP addresses from a central point and automatically sends a new
IP address when a computer is plugged into a different place in the network. DHCP uses
the concept of a “lease” or amount of time that a given IP address will be valid for a
computer. The lease time can vary depending on how long a user is likely to require the
Internet connection at a particular location. It’s especially useful in education and other
environments where users change frequently. Using very short leases, DHCP can
dynamically reconfigure networks in which there are more computers than there are
available IP addresses. DHCP supports static addresses for computers containing Web
servers that need a permanent IP address. DHCP enables the automatic reuse of unused
IP addresses. The Motorola Cellular Gateway NC800 contains a built-in DHCP server that
assigns private IP addresses to clients.
Directional
antenna
An antenna that concentrates transmission power into a direction, thereby increasing
coverage distance at the expense of coverage angle. Directional antenna types include
yagi, patch and parabolic dish.
Diversity
antennas
Two identical antennas located a small distance apart to reduce multipath distortion and
improve wireless reception. Properly placed diversity antennas improve Motorola Cellular
Gateway NC800 wireless reception.
DNS
The Domain Name System is the Internet system for converting domain names to IP
addresses. A domain name is a meaningful and easy-to-remember “handle” for an Internet
address. 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.
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.
Dotteddecimal
notation
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 Motorola Cellular Gateway NC800 LAN default
Motorola Cellular Gateway NC800 User Guide Version 2.0
Page 95 of 110
configuration, 192.168.100 represents the network address. In the final octet, the host
address can be from 2 to 254. See IP Addresses.
download
To copy a file from one computer to another. You can use the Internet to download files
from a server to a computer.
downstream
In a CDMA network, the direction of data received by the computer from the Internet.
driver
A software program that allows a computer to use and communicate with equipment or
peripherals installed on the computer. For example, network interface cards (NICs) require
drivers to allow the computer to communicate with the network through the NIC.
DSSS
Direct Sequence Spread Spectrum is an IEEE 802.11b RF modulation protocol. It combines
a data signal at the sending station with a higher data rate bit sequence, which many refer
to as a chip sequence (also known as processing gain). A high processing gain increases
the signal's resistance to interference. The minimum processing gain that the FCC allows is
10, and most products operate under 20.
DTIM
Dynamic IP
address
Delivery Traffic Indication Message.
An IP address that is automatically assigned to a client station in a TCP/IP network,
typically by a DHCP server. Network devices that serve multiple users, such as servers and
printers, are usually assigned static IP addresses.
encapsulate
To include data into some other data unit to hide the format of the included data.
encode
To alter an electronic signal so that only an authorized user can unscramble it to view the
information.
encrypt
To encode data.
endpoint
A VPN endpoint terminates the VPN at the gateway so that computers on the Motorola
Cellular Gateway NC800 LAN do not need VPN client software to tunnel through the
Internet to the VPN server.
ESP
Encapsulating Security Payload.
Ethernet
The most widely used LAN type, also known as IEEE 802.3. The most common Ethernet
networks are 10Base-T, which provide transmission speeds up to 10 Mbps, usually over
unshielded, twisted-pair wire terminated with RJ-45 connectors. Fast Ethernet (100Base-T)
provides speeds up to 100 Mbps. Base means baseband technology and T means twisted
pair cable. Each Ethernet port has a physical address called the MAC address.
Token Ring is another method to access a LAN, but not widely used. Ethernet can be used
on a shared network, where all clients share the bandwidth or on a switched network where
each sender and receiver pair has the full bandwidth. Ethernet uses a technology that
broadcasts each frame onto a medium such as wire or fiber. All computers, on the network,
are listening. The computer with the matching destination address accepts the frame and
checks for errors. Ethernet was invented in 1973 by Robert Metcalfe and David Boggs of
Xerox. It ran at 2.93 megabits per second (Mbps). Today Ethernet devices are available
that communicate at 1 gigabits per second (Gbps).
Fast Ethernet
An Ethernet Network that will support up to 100 megabits per second of data transfer.

FCS
Frame Check Sequence.
FHSS
Frequency Hopping Spread Spectrum - Takes the data signal and modulates it with a
carrier signal that hops from frequency to frequency as a function of time over a wide band
of frequencies.
firewall
A security software system on the Motorola Cellular Gateway NC800 that enforces an
access control policy between the Internet and the Motorola Cellular Gateway NC800 LAN.
A firewall determines which information passes in and out of a network.
firmware
Code that is written onto programmable read-only memory (PROM) or more recently
FLASH memory. Once firmware has been written onto the PROM or FLASH memory, it is
retained even when the device is turned off.
frequency
Number of times an electromagnetic signal repeats an identical cycle in a unit of time,
usually one second, measured in Hz, kHz, mHz, or GHz.
FTP
File Transfer Protocol - A member of the TCP/IP suite of protocols, used to copy files
between two computers on the Internet. Both computers must support their respective FTP
roles: one must be an FTP client and the other an FTP server. See also TCP/IP.
Full duplex
The ability to simultaneously transmit and receive data. See also half-duplex.
gateway
A device that enables communication between networks using different protocols. The
Motorola Cellular Gateway NC800 enables multiple computers supporting IEEE 802.11b/g
and/or Ethernet to share a single Internet connection. A gateway is often included as part of
a network switch. A gateway can also be implemented as software on a computer.
GHz
Gigahertz, which equals 1 billion cycles per second.
GUI
Graphical User Interface.
Half duplex
Network where only one device at a time can transmit data. See also full-duplex.
header
The data at the beginning of a packet that identifies what is in the packet.
hexadecimal
A base-sixteen numbering system that uses sixteen sequential numbers (0 to 9 and the
letters A to F) as base units before adding a new position. On computers, hexadecimal is a
convenient way to express binary numbers.
hub
A hub offers a single collision domain among multiple wired users. When one user's
Ethernet NIC sends data, all other stations connected to the LAN will hold off sending data
until the medium is idle. A traditional wireless access point (AP) most closely resembles a
hub. A hub performs no data filtering. See also bridge and gateway.
hop
The interval between two gateways on an IP network. The number of hops a packet
traverses toward its destination (called the hop count) is saved in the packet header. For
example, a hop count of six means the packet has traversed six gateways. The packet hop
count increases as the time-to-live (TTL) value decreases.
host
In IP, a host is any computer supporting end-user applications or services with full two-way
network access. Each host has a unique host number that combined with the network
number forms its IP address. Host also can mean:

standards that often become national and international standards. The organization
publishes a number of journals, has many local chapters, and several large societies in
special areas, such as the IEEE Computer Society. The IEEE (http://www.ieee.org) is
accredited by ANSI.
IEEE 802.3
See Ethernet.
IEEE 802.11b
One of the IEEE standards for wireless networking hardware. Products that adhere to a
specific IEEE standard will work with each other, even if they are manufactured by different
companies. The 802.11b standard specifies a maximum data transfer rate of 11Mbps, an
operating frequency of 2.4GHz, and WEP encryption for security.
It uses Direct Sequence Spread Spectrum modulation in the unlicensed 2.4 GHz frequency
band also used by cordless phones and microwave ovens, therefore range and throughput
are affected by 2.4 GHz phones and microwave ovens operating in the vicinity. 802.11b
networks are also referred to as WLAN networks.
IEEE 802.11g
Refers to the extension of the IEEE 802.11 standard for wireless networking. The 802.11g
specification used by the Motorola Cellular Gateway NC800 specifies a maximum data
transfer rate of 54Mbps using OFDM modulation, an operating frequency of 2.4GHz,
backward compatibility with IEEE 802.11b devices and WEP encryption as well as WPAPSK for security.
The higher speed comes from using Orthogonal Frequency Division Multiplexing (OFDM)
modulation. It is backwards compatible with 802.11b because it also uses the 2.4 GHz
frequency and is therefore also affected by 2.4 GHz phones and microwave ovens
operating in the vicinity.
IETF
The Internet Engineering Task Force (http://www.ietf.org) is an open international
community of network designers, operators, vendors, and researchers to develop and
maintain Internet architecture. Technical working groups issue working documents called
Internet-Drafts. The IETF publishes review versions of the drafts called requests for
comments (RFCs).

Internet
A worldwide collection of interconnected networks using TCP/IP.
internetwork
A collection of interconnected networks allowing communication between all devices
connected to any network in the collection.
IP
Internet Protocol is a set of standards that enable different types of computers to
communicate with one another and exchange data through the Internet. IP provides the
appearance of a single, seamless communication system and makes the Internet a virtual
network.
IP address
In the most widely installed level of the Internet Protocol (IP) today, an IP address is a 32binary digit number that identifies each sender or receiver of information that is sent in
packets across the Internet. When you request an HTML page or send e-mail, the Internet
Protocol part of TCP/IP includes your IP address in the message (actually, in each of the
packets if more than one is required) and sends it to the IP address that is obtained by
looking up the domain name in the Uniform Resource Locator you requested or in the email address you're sending a note to. At the other end, the recipient can see the IP
address of the Web page requester or the e-mail sender and can respond by sending
another message using the IP address it received.
TCP/IP networks therefore route messages based on the destination IP address. An IP
address has two parts:
• The network address is assigned by IANA.
• A host address.
The Motorola Cellular Gateway NC800 network administrator assigns a host address to
each host connected to the Motorola Cellular Gateway NC800. This is done either via a
static IP address or automatically using its DHCP server. 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 as network.network.network.host.
IPSec
The Internet Protocol Security protocols are described in IETF authentication and
encryption standards for secure packet exchange over the Internet. IPSec consists of a
suite of protocols used to implement secure exchange of packets at the IP layer (i.e. OSI
layer 3). IPSec supports two basic modes: Transport and Tunnel. Transport encrypts the
payload of each packet, leaving the header untouched, while Tunnel mode encrypts both
the header and the payload and is therefore more secure.
ISM Bands
Industrial, scientific, and medicine bands - Radio frequency bands that the Federal
Communications Commission (FCC) authorized for wireless LANs. The ISM bands are
located at 902 MHz, 2.400 GHz, and 5.7 GHz.
ISO
The International Organization for Standardization (http://www.iso.ch) is a worldwide
federation of national standards bodies from approximately 140 countries. ISO is a nongovernmental organization established in 1947 to promote the development of
standardization and related activities in the world with a view to facilitating the international
exchange of goods and services, and to developing cooperation in the spheres of
intellectual, scientific, technological, and economic activity.
ISP
An ISP (Internet Service Provider) is a company that provides individuals and companies
access to the Internet and other related services such as Web site building and virtual
hosting. An ISP can serve IP addresses dynamically, or assign static (fixed) IP addresses to
individual computers.

K, L
LAN
A LAN (Local Area Network) is a 2 – 1000 Mbps communications network that extends no
more than a few hundred meters, usually using Ethernet as the physical layer.
layer
In networks, layers are software protocol levels. Each layer performs functions for the layers
above it. OSI is a reference model having seven functional layers.
LED
Light Emitting Diode - Small lights that are typically used to indicate status on electronic
equipment. They come in almost any color with the most common being red, green, yellow
and recently, blue.
loopback
A test that loops the transmit signal to the receive signal. Usually the loopback test is
initiated on a network device. The test is used to verify a path or to measure the quality of a
signal on that path.
MAC
The Media Access Control address is a unique, 48-bit value permanently saved in ROM at
the factory to identify each Ethernet network device. It is expressed as a sequence of 12
hexadecimal digits. Also called an Ethernet address, physical address, hardware address,
or NIC address.
MB
One megabyte; equals 1,024 x 1,024 bytes, 1,024 kilobytes, or about 8 million bits.
Mbps
Million bits per second (megabits per second). A rate of data transfer.
media
The various physical environments through which signals pass; for example, coaxial,
unshielded twisted-pair (UTP), or fiber-optic cable.
MHz
Megahertz. One million cycles per second. A measure of radio frequency.
MRU
The MRU (Maximum Receive Unit) sets the maximum number of bytes that PPP is capable
of receiving in one PPP packet. Generally, the bigger the better.
The Maximum Transmission Unit is the largest amount of data that can be transmitted in
one discrete message on a given physical network. The MTU places an upper bound on the
size of a message that can be transferred by the network in a single frame. Messages
exceeding the MTU must be fragmented before transmission, and reassembled at the
destination.
MTU
multicast
A data transmission sent from one sender to multiple receivers. See also broadcast and
unicast.
NAT
Network Address Translation - An Internet standard that enables a local-area network
(LAN) to use one set of IP addresses for internal traffic and a second set of IP addresses
for external traffic. A NAT box located where the LAN meets the Internet makes all
necessary IP address translations. NAT provides some security
because the IP addresses of the LAN computers are invisible on the Internet.
NAPT
Network Address Port Translation is the most common form of address translation between

See Subnet Mask.
Omnidirectional
antenna
OFDM
An antenna that provides a 360-degree transmission pattern. These types of antennas are
used when coverage in all directions is required.
Open Systems
Authentication
The IEEE 802.11 default authentication method is a two-step process. First, the station
wanting to authenticate with another station sends an authentication management frame
containing the sending station's identity. The receiving station then sends back a frame
alerting whether it recognizes the identity of the authenticating station.
OSI
The Open Systems Interconnection reference model is an illustrative model describing how
data moves from an application on the source host through a network to an application on
the destination host. It is a conceptual framework developed by ISO that is now the primary
model for intercomputer communications. OSI is a model only; it does not define a specific
networking interface.
Developed for wireless applications, Orthogonal Frequency Division Multiplexing
technology offers superior performance increased data rates and more reliable
transmissions than previous technologies, such as DSSS. OFDM is a scheme in which
numerous signals of different frequencies are combined to form a single signal for
transmission on the medium. OFDM works by breaking one high-speed data stream into a
number of lower speed data streams, which are then transmitted in parallel. Each lower
speed stream is used to modulate a sub carrier. Essentially, this creates a multi-carrier
transmission by dividing a wide frequency band or channel into a number of narrower
frequency bands or sub-channels. OFDM is also used for other applications, including
power line networking.
packet
The unit of data that is routed between the sender and destination on the Internet or other
packet-switched network. When data such as an e-mail message or other file is sent over
the Internet, IP on the sender divides the data into uniquely-numbered packets.The packet
Motorola Cellular Gateway NC800 User Guide Version 2.0
Page 101 of 110
header contains the source and destination IP addresses. The individual packets may travel
different routes. When all packets arrive at the destination, the IP at that end reassembles
the packets. The header and the data can vary in length. Packet and datagram are similar
in meaning.
Packetswitched
A scheme to handle transmissions on a connectionless network such as the Internet. An
alternative is circuit-switched.
PCMCIA
The Personal Computer Memory Card International Association sets international standards
for connecting peripherals to portable computers. Laptop computers typically have a
PCMCIA slot that can hold one or two PC Cards to provide features such as Ethernet
connectivity.
PDA

transmission link between open systems. It entails the electrical, mechanical, and
handshaking procedures.
PING
A network utility that tests host reachability by sending a small packet to the host and
waiting for a reply. If you PING a computer IP address and receive a reply, you know the
computer is reachable over the network. It also stands for Packet InterNet Groper.
port
On a computer or other electronic device, a port is a socket or plug used to physically
connect it to the network or to other devices. In TCP/IP, a port is a number from 0 to 65536
used logically by a client program to specify a server program. Ports 0 to 1024 are reserved

PPP
PPP (Point to Point Protocol) is a protocol for communication between computers using a
serial interface, typically a personal computer connected by phone line to a server.
PPPoE
Point to Point Protocol over Ethernet.
PPTP
Point-to-Point Tunneling Protocol encapsulates other protocols. It is a protocol that allows
corporations to extend their own corporate network through private “tunnels” over the public
Internet. Effectively, a corporation uses the wide-area network to create a large virtual
private network.
Private IP
address
An IP address assigned to a computer on the Motorola Cellular Gateway NC800 LAN by
the DHCP server on the Motorola Cellular Gateway NC800 for a specified lease time.
Private IP addresses are used by the Motorola Cellular Gateway NC800 LAN only; they are
invisible to devices on the Internet. See also public IP address.
protocol
A formal set of rules and conventions for exchanging data. Different computer types (for
example PC, UNIX, or mainframe) can communicate if they support common protocols.
Proxy server
A piece of software that sits between a client application (such as a Web browser) and the
Internet. It intercepts all traffic flowing between the two and analyzes them. This allows
proxy servers to do two important things. One is to boost Internet access speeds for groups
of users. Since the proxy server stores a "cache" of recently downloaded Web sites, any
user that tries to access a Web site that has recently been accessed by another user is
simply sent the cached version from the proxy server. The other important function is
filtering. A proxy server can be set up to filter all attempts by users to access specific Web
sites.
PSTN
The public switched telephone network is the traditional circuit-switched, voice-oriented
telephone network. See also POTS.

RIP
Routing Information Protocol - A common type of routing protocol. RIP bases its routing
path on the distance (number of hops) to the destination. RIP maintains optimum routing
paths by sending out routing update messages if the network topology changes. For
example, if a gateway finds that a particular link is faulty, it will update its routing table, and
then send a copy of the modified table to each of its neighbors.
RJ-11
The most common type of connector for household or office phones.
RJ-45
A connector for Cat 5 or Cat 5e cable, with 8 pins. It looks similar to a typical telephone wire
connector that only has 4 or 6 pins, but it is larger in size.
roaming
A feature of some access points or gateways that allow users to move through a facility
while maintaining an unbroken connection to the LAN.
routing table
A table listing available routes that is used by a gateway to determine the best route for a
packet.
RTS
Request To Send.
scope
The set of IP addresses that a DHCP server can lease to clients.
server
A host computer that stores information and software programs used by other computers in
a network (it “serves” the programs and information to other computers). Examples of
services are file transfer, remote login and printing services.
Shared key
authentication
A type of authentication that assumes each station has received a secret shared key
through a secure channel independent from an 802.11 network. Stations authenticate
through shared knowledge of the secret key. Use of Shared Key authentication requires
implementation of the 802.11 Wireless Equivalent Privacy (WEP) algorithms.
SOHO
Small Office Home Office
spectrum
A specified range of frequencies used for transmission of electromagnetic signals.
spectrum
allocation
An allocation of portions of the available electromagnetic spectrum for specific services,
such as AM, FM, or personal communications.
SSID
Service Set Identifier - An identification name that wireless devices use to make
connections. In order for wireless devices to communicate, they must all be set to the same
channel and they all must use the same SSID. For instance, if you are using an access
point to connect two computers using wireless devices, the access point and each of the
wireless devices must use the same SSID. Even if they are set to the same channel, they
cannot communicate unless the SSID is the same.
Stateful
inspection
A type of firewall that tracks each connection traversing all firewall interfaces to ensure
validity. In addition to examining the source and destination in the packet header based on
static rules, a stateful inspection firewall:
• Examines packet headers on context established by previous packets that
traversed the firewall
Monitors the connection state and saves it in a table
•
• Closes ports until a connection to a specific port is requested
• May examine the packet contents up through the application layer to determine

A stateful-inspection firewall is more advanced than a static filter firewall.
Static filter
A type of firewall that examines the source and destination in the packet header based on
administrator-defined rules only.
Static IP
Address
A permanent IP address that is assigned to a host in a TCP/IP network. Normally, a static
IP address must be assigned manually. The opposite of dynamic IP address.
Static route
A manually-defined route.
station
IEEE 802.11b term for wireless client.
Subnet
A network segment connected by hubs or repeaters. Subnets can stand alone or can be
connected to other subnetworks onto a larger network. When subnetting is used, the host
portion of the IP address is divided into a subnet and host number. Hosts and gateways use
the subnet mask to identify the bits used for the network and subnet number.
Subnet mask
The method used for splitting IP networks into a series of subgroups, or subnets. The mask
is a binary pattern that is logically ANDed with the IP address to turn part of the host ID
address field into a field for subnets. A gateway routes packets using the network prefix and
the subnet number part of the IP address.
switch
A switch is more sophisticated than a hub and connects one user to another without
blocking access of other users. The switch improves throughput because of the smaller
resulting collision domains. Users don't have to wait until others are finished before sending
data.
SYSLOG
A de-facto UNIX standard for logging system events.
TCP
Transmission Control Protocol - A method (protocol) used along with the IP (Internet
Protocol) to send data in the form of message units (datagram) between network devices
over a LAN or WAN. Transmission Control Protocol on OSI transport layer four, provides
reliable transport over the network for data transmitted using IP (network layer three). It is
an end-to-end protocol defining rules and procedures for data exchange between hosts on
top of connectionless IP. TCP uses a timer to track outstanding packets, checks errors in
incoming packets, and retransmits packets if requested.TCP is known as a "connection
oriented" protocol due to requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet resulting in transmission control.
TCP/IP
Transmission Control Protocol/Internet Protocol - The basic communication language or set
of protocols for communications over a network (developed specifically for the Internet).
TCP/IP defines a suite or group of protocols and not only TCP and IP.
TFTP
Trivial File Transfer Protocol is a scaled down version of the well known FTP protocol
commonly used for file transfer over the Internet. Being a scaled down protocol, it is ideal
for use in an embedded environment such as a wireless gateway. It is used to upload new
firmware to the Motorola Cellular Gateway NC800.
Transparent
bridging
A method to enable all hosts on the wired Ethernet LAN and IEEE 802.11b wireless LAN to
communicate as if they were all connected to the same physical network.
Transport
layer
Layer of the OSI concerned with protocols for error recognition and recovery. This layer
also regulates information flow.
TTL
The time to live is the number of gateways (or hops) a packet can traverse before being

tunnel
discarded. When a gateway processes a packet, it decreases the TTL by 1. When the TTL
reaches zero, the packet is discarded.
To place packets inside other packets to send over a network. The protocol of the enclosing
packet is understood by each endpoint, or tunnel interface, where the packet enters and
exits the network. VPNs rely on tunneling to create a secure network.Tunneling requires the
following protocol types:
• A carrier protocol, such as TCP, used by the network that the data travels over
• An encapsulating protocol, such as IPSec, L2F, L2TP, or PPTP, that is wrapped
around the original data
•
A passenger protocol, such as IP, for the original data.
UDP
User Datagram Protocol - A method (protocol) used along with the IP (Internet Protocol) to
send data in the form of message units (datagrams) between network devices over a LAN
or WAN. UDP is an OSI layer four protocol, while IP is a layer three protocol. UDP is known
as a “connection-less” protocol due to NOT requiring the receiver of a packet to return an
acknowledgment of receipt to the sender of the packet (as opposed to TCP).
unicast
A point-to-point data transmission sent from one sender to one receiver. This the normal
way you access websites. See also broadcast and multicast.
URL
Universal Resource Locator - URLs are the Internet equivalent of addresses. How do they
work? Like other types of addresses, they move from the general to the specific (from zip
code
to
recipient,
so
to
speak).
Take
this
URL,
for
example:
www.motorola.com/CellularGateway/index.html. First you have the protocol: http:/ then the
server address or domain: /www.motorola.com and finally the directory:
/CellularGateway/ in which the file index.html resides.
USB
Universal Serial Bus is a computer interface for add-on devices such as printers, scanners,
mice, modems, or keyboards. USB supports data transfer rates of 12 Mbps and plug-andplay installation. You can connect up to 127 devices to a single USB port.
UTP
Unshielded Twisted Pair. Also referred to as 10BASE-T or 100BASE-T network cable.
VLAN
A virtual local area network is group of devices on different LAN segments that are logically
configured to communicate as if they are connected to the same wire.
VoIP
Voice over Internet Protocol is a method to exchange voice, fax, and other information over
the Internet. Voice and fax have traditionally been carried over traditional telephone lines of
the PSTN using a dedicated circuit for each line. VoIP enables calls to travel as discrete
data packets on shared lines. VoIP is an important part of the convergence of computers,
telephones, and television into a single integrated information network.
VPN
Virtual Private Network - Virtual Private Networks allows computers to use the public
Internet backbone as a channel for private data communication. With encryption and
encapsulation technology, a VPN creates a private passageway (tunnel) through the
Internet. VPNs allow remote offices, company road warriors, and even businesses'
customers to use the Internet, rather than pricey private lines, to reach company networks.
A VPN connection provides security and performance similar to a dedicated link (for
example, a leased line), but at much lower cost.

W
WAN
Wide Area Network. A wide-area network provides a connection over a large geographic
area, such as a country or the whole world. The bandwidth depends on need and cost, but
is usually much lower than for a LAN.
WAP
Wireless Access Point or Wireless Access Protocol. See also access point.
WECA
Wireless Ethernet Compatibility Alliance - An alliance of companies throughout the world
that promote the use of the IEEE 802.11 standard in wireless technology. It is a trade
organization that works to ensure that all wireless IEEE 802.11b Wi-Fi devices such as
computer cards, laptops, air gateways, PDAs, etc. can communicate with each other.
WEP
Wired Equivalent Privacy encryption protects the privacy of data transmitted over a wireless
LAN. WEP uses keys to encrypt and decrypt transmitted data. The access point must
authenticate a client before it can transfer data to another client. WEP is part of IEEE
802.11b. It is based on a 64- or 128- bit shared key algorithm, as described in the IEEE
802.11b standard.
WEP network
key
A network key is a key used for network encryption under the WEP algorithm. Under
802.11, a wireless station can be configured with up to four network keys, with the key
index values being 1, 2, 3, and 4. When an access point or a wireless station transmits an
encrypted message using a key that is stored in a specific key index, the transmitted
message indicates the key index that was used to encrypt the message body. The receiving
access point or wireless station can then retrieve the key that is stored at the key index and
use it to decode the encrypted message body.
Wi-Fi
Wireless Fidelity - The IEEE 802.11 High Rate Standard used in wireless technology. The
Wi-Fi (pronounced y-phi) seal of approval assures the end customer of interoperability with
other network cards and access points which also bear the Wi-Fi logo. Wi-Fi is the brand
name applied to products supporting IEEE 802.11 or WLAN.
WINS
Short for Windows Internet Naming Service, a system that determines the IP address
http://www.webopedia.com/TERM/W/IP_address.html associated with a particular network
computer. This is called name resolution. WINS supports network client and server
computers running Windows and can provide name resolution for other computers with
special arrangements. Determining the IP address for a computer is a complex process
when DHCP servers assign IP addresses dynamically. For example, it is possible for DHCP
to assign a different IP address to a client each time the machine logs on to the network.
WINS uses a distributed database that is automatically updated with the names of
computers currently available and the IP address assigned to each one. DNS is an
alternative system for name resolution suitable for network computers with fixed IP
addresses.
Wireless
network
interface
Couples the digital signal from the end-user appliance to the wireless medium, which is air.
WLAN
Wireless Local Area Network - A group of computers and associated devices that
communicate with each other wirelessly. Wireless LANs are used increasingly in both home
and office environments.
WWW
World Wide Web - The Internet's multimedia service containing countless areas of
information, documentation, entertainment, as well as business and personal home
pages. It is an interface to the Internet that you use to navigate and hyperlink to information.

Appendix D: Upgrading the Motorola Cellular Gateway NC800
firmware using TFTP
Trivial File Transfer Protocol (TFTP) is a scaled down version of the well-known FTP protocol commonly used
for file transfer over the Internet. Being a scaled down protocol, it is ideal for use in an embedded environment
such as a wireless gateway. It offers an alternative method of firmware upgrading to the web-based method.
The Motorola Cellular Gateway NC800 accepts TFTP file transfers only during the first three seconds after
boot up.
To upgrade the Motorola Cellular Gateway NC800’s firmware using TFTP follow these steps:
Open a TFTP compatible client on a PC connected to the primary LAN of the Gateway. The PC must be
configured with a static IP address on the same subnet as the Gateway (The user must be able to
successfully ping the Gateway’s primary LAN IP address from the PC).
Specify the Gateway’s Primary LAN IP address in the TFTP client.
Specify binary mode for file transfer.
Type PUT firmware.trx where firmware.trx is the full path to the new firmware file.
Reset the Motorola Cellular Gateway NC800 by pressing the Reset button at the back of the Motorola
Cellular Gateway NC800.
Hit the Enter button to issue the PUT firmware.trx command.
The TFTP client reports the progress / result of the file transfer.
If successful, the Motorola Cellular Gateway NC800 reboots using the new firmware image after
approximately 30 seconds (it first writes the new image to FLASH once it has been transferred).
