UNIVERSAL SUBSCRIBER GATEWAY™
About the NOMADIX Network Service Engine (NSE)
More than 50 million mobile enterprise users carry laptops and hand-held computers
as they move about. Network equipment manufacturers must eliminate the concerns
of security and connectivity that are associated with a mobile workforce. Nomadix
developed an embedded software mobility solution called the Network Service
Engine (NSE), creating a robust networking environment where connectivity
problems and concerns about security are things of the past.
Nomadix licenses the NSE to makers of edge
networking devices such as wireless access points,
routers, switches, and residential gateways.
Some of the NSE’s key product offerings include:
10
!
Transparent Connectivity
Our patented Dynamic Address Translation™ (DAT™) technology provides
mobile users with transparent broadband network connectivity—no need for
changes to their computer's settings, and no need for any special client-side
software. By simply adapting to the user (instead of the user adapting to the
network), the NSE ensures that everyone gets effortless access to any
enterprise, residential, or public-access broadband network.
!
Policy-based Traffic Shaping
The NSE caps bandwidth usage on a per device basis ensuring equitable
distribution of bandwidth in networks that are heavily congested. The
bandwidth for each device can be defined asymmetrically for both upstream
and downstream data transmissions, allowing efficient bandwidth utilization
across the entire network.
!
Network-based Security
The NSE utilizes SSL to deliver Web-based user authentication that is
secure, efficient, transport agnostic (wireless and wired), and low cost. Our
Web-based model standardizes authentication across multiple vendors and
network types.
Introduction
UNIVERSAL SUBSCRIBER GATEWAY™
The NSE is designed for the following critical application areas:
!
Enterprise
IT administrators can deploy NSE-enabled wireless Access Points to
enhance today’s security implementations (that focus on the privacy of the
data) by providing a Web-based, vendor and client-independent solution that
securely authenticates the user to the network over SSL. The NSE enables
the deployment of policy-based access and easily integrates into existing
centralized authentication databases, providing greater security to the
wireless LAN. The NSE also enables transparent subnet roaming, allowing
the deployment of multiple wireless subnets and limiting the available
bandwidth of users per Access Point—enabling a more cost effective,
scalable deployment of wireless LANs.
!
Public-LAN
By using an NSE-enabled edge networking device, service providers can
instantly deliver transparent broadband access to any customer at any public
access location—without requiring the user to reconfigure their computer or
use client-side software. Customers can create accounts at the public access
location in real time and receive local content and services from the service
provider or premise owner. The NSE can pass the necessary parameters for
authentication and billing to the service provider allowing settlement to
occur. The NSE provides the intelligence necessary to capture customers onsite without the need for call center support functions or the provisioning of
expensive client-side software.
!
Residential
Providers of residential broadband Internet access can deploy an NSEenabled gateway in the home to deliver broadband access to any consumer.
Our patented Dynamic Address Translation™ technology means customers
won't need to reconfigure their computer or use any special client-side
software, dramatically reducing technical support costs and product return
rates. The NSE automatically redirects consumers to the service provider's
portal page to create accounts and receive local content and services
generating an immediate revenue stream. The NSE passes all necessary
parameters for authentication and billing back to the service provider's
infrastructure for settlement to occur.
The NSE is completely modular, allowing you to choose only those features needed
for your specific application.
Introduction
11
UNIVERSAL SUBSCRIBER GATEWAY™
Welcome to the Universal Subscriber Gateway™
In addition to licensing its NSE technology solution to makers of edge networking
devices, Nomadix has created its own robust platform for the NSE, called the
Universal Subscriber Gateway (USG). The USG is a stand-alone, turnkey networking
device that provides important user mobility and security enhancements to network
infrastructures.
Universal Subscriber Gateway
The Universal Subscriber Gateway handles universal mobile connectivity, advanced
security, policy-based traffic shaping, and service placement supporting up to 2,000
users simultaneously in a broadband environment. Available in a variety of
configurations, the USG also offers a unique set of security and connectivity features
for deploying wireless 802.11 networks.
The USG yields a complete solution to a set of complex issues in the Enterprise,
Public-LAN, and Residential segments.
Leveraging Services
Resolving configuration conflicts is difficult and time consuming for network users
who are constantly on the move, and costly to the solution provider. In fact, most
users are reluctant to make changes to their computer’s network settings and won’t
even bother. This fact alone has prevented the widespread deployment of broadband
network services. Our patented Dynamic Address Translation (DAT) technology
provides transparent and seamless broadband connectivity to any user at any location,
without the need for configuration changes to the client computer or any client-side
software.
"
12
In general, this User’s Guide refers to the Universal Subscriber
Gateway as the “USG” or the “system,” with occasional references to
the “product.”
Introduction
UNIVERSAL SUBSCRIBER GATEWAY™
Product Overview
The Universal Subscriber Gateway is deployed in any wireless or wired broadband
service network. The USG immediately recognizes new users on the network (and
remembers returning users) and redirects their browser to a proprietary Web page
where they can purchase high speed Internet access and services from the network
solution provider. Users who choose to purchase network access and services are
known as “subscribers.”
The USG is a free-standing or rack-mounted unit with two Ethernet ports (network
and subscribers), a serial port for system management and administration, and a
dedicated PMS port for connecting the unit to a customer’s Property Management
System. After the initial setup and network configuration is established, the USG is
easily managed by a network administrator through a Telnet interface, Web
management interface, SNMP client, or the onboard serial port.
The USG is a multinational product that supports Asian and European languages.
Product Configurations and Licensing
The Universal Subscriber Gateway can be licensed for various configurations,
including custom configurations. The following product configurations are available:

UNIVERSAL SUBSCRIBER GATEWAY™
PPTP Support
The USG fully supports PPTP (Point-to-Point Tunneling Protocol) so that
misconfigured users (DHCP private or statically misconfigured) can use PPTP VPNs
through the USG’s Dynamic Address Translation (DAT) function. Our patented DAT
technology ensures that this feature is “transparent” to users. The USG supports a
maximum of 500 simultaneous PPTP sessions. See also, “Misconfigured User” on
page 238.
E-mail Redirection
Today’s increasingly sophisticated computer users are mobile and demanding. They
want more than simple Internet access. When they “plug in” they not only expect a
reliable and fast connection, they need to be able to make full use of their normal Web
and business applications (for example, E-mailing).
System administrators can set the USG to pass all SMTP traffic through the SMTP
relay server independent of a PC’s settings.
With the USG’s outgoing E-mail Redirection feature, the system allows
misconfigured users to send E-mail without the need for complex reconfiguration
tasks. For example, if you are connected to a broadband network via the USG in a
hotel and you want to send E-mail, the USG rewrites your original message according
to SMTP rules and sends it out via its E-mail server. The recipient of your E-mail sees
the message as if you sent it from your local Internet Service Provider, not from the
hotel.
DNS Redirection
The Domain Name System (DNS) maps a host name with its IP address on the
Internet. DNS runs over UDP (User Datagram Protocol) which is not a reliable
protocol, and it is up to the application to retransmit requests if the DNS requests are
lost or no reply is sent. Subscribers may also have their laptop configured for a DNS
server which exists on an enterprise network behind a firewall. To improve reliability
and to ensure that a DNS server is always available to subscribers, the USG can
redirect requests to a local DNS server on behalf of subscribers. This improves the
response time and enables true plug-and-play access when the subscriber’s
configured DNS server is behind a firewall or located on a private Intranet.
Microsoft NetMeeting® Support
Our patented Dynamic Address Translation (DAT) plug-and-play technology
supports the Microsoft NetMeeting® product.

Introduction
UNIVERSAL SUBSCRIBER GATEWAY™
Authentication and Billing
SSL Support
This feature allows for the creation of an end-to-end encrypted link between the USG
and wireless clients by enabling the Internal Web Server (IWS) to display pages under
a secure link—important when transmitting AAA information in a wireless network
when using RADIUS.
Adding SSL support to the USG requires service providers to obtain digital
certificates from VeriSign™ to create HTTPS pages. Instructions for obtaining
certificates are provided by Nomadix.
Authentication
The USG enables support for port-based authentication using 802.1x and other
authentication methods used by various Smart Clients, while also allowing the secure
passing of authentication parameters through SSL using a Web-based Universal
Access Method (UAM). The USG’s advanced security feature enables the support of
a wide variety of authentication methods within the network.
The USG also offers a sophisticated 802.1x/UAM Dual Mode feature that
transparently supports concurrent 802.1x and UAM authentication, using all principal
mechanisms including 802.1x supplicants, OS-driven implementations, Smart
Clients, standard RADIUS logins, PMS, and Credit Card Billing. This comprehensive
new authentication logic means that the previous sequential authentication logic is
now available without any wait time parameters which dramatically improves the
ease of deploying 802.1x in a secure Hot Spot network.
In addition, the USG includes enhanced tracking, billing and security features for
Web-based self-provisioning, including RADIUS Authentication, Authorization and
Accounting (AAA), credit card, and Property Management System (PMS) billing.
AAA Passthrough Port
System administrators can set the USG to passthrough any port (except 80, 1111,
1112, and 2111), without being redirected. Once access to a non-passthrough port
address (for example, search engine) has been requested, the subscriber is then
redirected as usual.
Introduction
17
UNIVERSAL SUBSCRIBER GATEWAY™
Portal Page Parameter Passing
The USG contains a comprehensive HTTP page redirection logic that allows for a
page redirect before (also known as, Portal Page Redirect) and/or after the
authentication process (also known as, Home Page Redirect). As part of the Portal
Page Redirect feature, the USG can send a defined set of parameters to the portal page
redirection logic that allows an External web Server to perform a redirection based
on:
!
!
!
VLAN ID
Subscriber MAC address
Externally hosted RADIUS login failure page
This means that the network administrator can now perform location-specific service
branding (for example, an airport lounge) from a centralized Web server.
"
If you plan to implement Portal Page Redirect by VLAN ID, please go to
“Contact Information” on page 225 and contact Nomadix Technical
Support for more information.
Cookie Placement (“Remember My Login”)
This feature allows the Internal Web Server (IWS) to store an encrypted login cookie
in the browser to remember logins, using usernames, passwords and NAIs between
Access Points. This functionality creates a more efficient and better user experience
in wireless networks.
Dynamic Billing Selection
This feature allows subscribers to switch between billing options from the
Information and Control Console (ICC) and offers a wide range of billing schemes to
subscribers, even the ability to assign sessions by the minute.
XML Support
"
If you plan to implement XML for external billing, please contact
technical support for the XML specification of the USG. Refer to
“Technical Support” on page 231.
XML (eXtensible Markup Language) is used by the USG’s subscriber management
module for room and user administration. The XML interface allows the USG to
accept and process XML commands from an external source. XML commands are
sent over the network to the USG which executes the commands, and returns data to
the system that initiated the command request. XML enables solution providers to
customize and enhance their USG installations.
18
Introduction
UNIVERSAL SUBSCRIBER GATEWAY™
PMS Integration
The USG can be integrated with existing Property Management Systems. For
example, by integrating with a hotel’s PMS, the USG can post charges for Internet
access directly to a guest’s hotel bill. In this case, the guest is billed only once. The
USG outputs a call accounting record to the PMS system whenever a subscriber
purchases Internet service and decides to post the charges to their room. The USG is
equipped with a dedicated PMS port to facilitate connectivity with a customer’s
Property Management System. For the hospitality environment, the following
additional PMS protocols are available:
!
!
!
Fidelio
PTI
Holodex
"
Some Property Management Systems may require you to obtain a
license before integrating the PMS with the USG. Check with the PMS
vendor.
"
Some Property Management Systems may use interfaces that are
incompatible with the USG. If your USG is having trouble
communicating with a solution provider’s PMS, please contact technical
support. Refer to “Technical Support” on page 231.
PMS Query
The USG can query most popular Property Management Systems for confirmation of
the “names” and “room numbers” of hotel guests—effectively becoming a “clone” of
a popular Micros POS system. This functionality allows hotels to seamlessly deploy
wireless networks (or alternatively use low-cost wired access concentration
equipment) that either do not support port-ID or do so in a proprietary format that
Nomadix does not currently support—and still be able to bill directly to the room.
Introduction
19
UNIVERSAL SUBSCRIBER GATEWAY™
Billing Records Mirroring
Multiple USG units can send copies of credit card and Property Management System
(PMS) billing records to external servers that have been previously defined by system
administrators. The USG assumes control of billing transmissions and saving billing
records. By effectively “mirroring” the billing data, the USG can send copies of
billing records to predefined “carbon copy” servers. Additionally, if the primary and
secondary servers are down, the USG can store up to 2,000 PMS or credit card
transaction records. The USG regularly attempts to connect with the primary and
secondary severs. When a connection is re-established (with either server), the USG
sends the cached information to the server. Customers can be confident that their
billing information is secure and that no transaction records are lost.
RADIUS Support
With the appropriate product license, the USG supports Remote Authentication DialIn User Service (RADIUS). RADIUS is an authentication and accounting system
used by many Internet Service Providers (ISPs).
RADIUS enables ISPs to maintain a very large central database of users. By using
RADIUS, service providers can implement policy-based management of their
subscriber base. RADIUS also helps ISPs to collect statistical data about their
networks (for example, the amount of time users spend online).
By integrating RADIUS with the USG platform, ISPs can now store in the RADIUS
database the bandwidth each subscriber is allocated. For example, when a subscriber
logs in, the RADIUS server will send the USG the bandwidth parameters and the
USG will obey them. If a subscriber wants a faster bandwidth, they can simply go to
their ISP’s home page, select the new service, and log in again. In this event, the ISP
can collect the data provided by the subscriber’s input and update the subscriber’s
RADIUS record. Whenever the subscriber logs in, RADIUS informs the USG of the
subscriber’s new parameters.
The USG’s RADIUS functionality also includes an accounting feature that allows the
USG to post “accounting start” and “accounting stop” records to the RADIUS server.
ISPs can use these records to accurately track the usage on their networks.
Some of the key benefits of supporting RADIUS include:
!
!
!
!
!
Minimal administrator setup tasks.
No human intervention.
No technical support calls to effect changes.
Subscribers can control their own level of service.
Allows ISPs to track the usage on their networks.

Introduction
UNIVERSAL SUBSCRIBER GATEWAY™
RADIUS Portal Redirect
This feature allows the USG to receive a Nomadix VSA from the RADIUS server for
URL redirection, and provides a method for users to be redirected to a different site
when logging in, based on a predefined RADIUS attribute.
Automatic User Tracking, Billing, and Security
The Authentication, Authorization, and Accounting (AAA) module of the USG offers
powerful tracking, billing, and security features.
The first time a subscriber accesses a network, the USG directs their browser to a
sign-in page. The USG’s adaptive configuration technology then creates a database
entry that automatically records their computer’s MAC address and network settings
and integrates these with a credit card authorization system to enable accurate, secure,
and efficient billing functionality.
The USG constantly tracks network settings for each subscriber on the network,
eliminating the need for further sign-ins. The database log generated by the USG
allows the solution provider to accurately track usage. The subscriber’s activity on the
network is logged and billed through the USG’s AAA module which accommodates
user name and password security, credit card billing (for example, communication
with AuthorizeNet), and per room/unit billing through Port-Location mapping
support.

Port-Location Mapping
The USG can provision subscriber access to the network on a localized port basis. For
example, in an apartment building environment, a solution provider may want to
provision Internet access to individual apartments, where each apartment is assigned a
port-location tag. In this scenario, the apartment tenant can choose to subscribe to the
service and the USG will then allow Internet access from the tenant’s apartment,
regardless of which computer (MAC address) is being used.
Port-locations can be “tagged” at any level (for example, a specific room in a hotel or
apartment building, a floor number, wing, or building). There may even be multiple
ports tagged to a single room. The USG uses a Port-Location Authorization Table
(similar to a MAC authorization table) to manage the assigned ports and ensure
accurate billing for services used by a particular port.

Setting a port to the Block mode will prevent subscribers from purchasing
new Internet access from the blocked port. Existing subscribers will continue
to have access to the Internet until the access has expired, and they will not
be able to purchase a new service.
To manage the subscriber or device on the subscriber side of the USG, you
must add the MAC address of the device or the subscriber’s IP address to the
subscriber table.
The Port-Location Mapping listing must be created if the PMS feature is
enabled. This is required to identify the port.
Introduction
UNIVERSAL SUBSCRIBER GATEWAY™
In-Room Port Mapping
System administrators can set the properties for each room from the subscriber side of
the USG. The system automatically detects which port number the administrator is
using and allows them to enter the fields for the room corresponding to the port they
are using.
Serial Printing
The USG supports ASCII serial printing functionality when a serial printer is
connected to the USG’s PMS port. You set up the serial printer connection from the
PMS menu.
Local Service Presentation
Information and Control Console (ICC)
The ICC is a JAVA pop-up window that is presented to subscribers with their Web
browser. The ICC allows subscribers to select their bandwidth and billing options
quickly and efficiently from a simple pull-down menu. For PMS and credit card
accounts, the ICC displays a dynamic “time” field to inform subscribers of the time
remaining on their account. Additionally, the ICC offers service providers an
opportunity to display advertising banners and present a choice of redirection options
to their subscribers.
See also:
!
“Information and Control Console (ICC)” on page 181.
Selective Access Control (Walled Garden)
The USG provides up to 300 IP passthrough addresses (and/or DNS entries), allowing
you to create a “Walled Garden” within the Internet where unauthenticated users can
be granted or denied access to sites of your choosing.
Home Page Redirection
The USG supports a comprehensive HTTP redirect logic that allows network
administrators to define multiple instances to intercept the browser’s Home Page
Request and replace it with freely configurable URLs. Portal page redirect enables
redirection to a portal page before the authentication process. This means that anyone
will get redirected to a Web page to establish an account, select a service plan, and
pay for access. Home Page redirect enables redirection to a page after the
authentication process (for example, to welcome a specific user to the service—after
the user has been identified by the authentication process.
Introduction
23
UNIVERSAL SUBSCRIBER GATEWAY™
IP Upsell
System administrators can set two different DHCP pools for the same physical LAN.
When DHCP subscribers select a service plan with a public pool address, the USG
associates their MAC address with their public IP address for the duration of the
service level agreement. The opposite is true if they select a plan with a private pool
address. This feature enables a competitive solution and is an instant revenue
generator for ISPs.
The IP Upsell functionality solves a number of connectivity problems, especially with
regard to L2TP, IP Sec, and certain video conferencing and online gaming
applications.
URL Filtering
The USG can restrict access to specified Web sites based on URLs defined by the
system administrator. URL filtering will block access to a list of sites and/or domains
entered by the administrator using the following three methods:
1.
Host IP address (for example, 1.2.3.4).
2.
Host DNS name (for example, www.yahoo.com).
3.
DNS domain name (for example, *.yahoo.com, meaning all sites under the
yahoo.com hierarchy, such as finance.yahoo.com, sports.yahoo.com, etc.).
The system administrator can dynamically add or remove up to 300 specific IP
addresses and domain names to be filtered for each property.
Nomadix Connection Screen & Partner Image
The USG allows the Nomadix connection screen (and partner image) to be displayed
even when AAA is turned “off.”
Flexible Screen Size & JAVA Detect
To support PDAs and other hand-held devices, the USG automatically formats the
Internal Web Server (IWS) pages to a screen size that is optimal for the particular
device being used. Since most PDAs today do not support JAVA applets, the USG
contains the intelligence necessary to prevent inconclusive JAVA error messages that
may be caused by the IWS.
Language Support
The USG’s subscriber interface supports many Asian and European languages.

Introduction
UNIVERSAL SUBSCRIBER GATEWAY™
Bandwidth Management
Bandwidth Shaping (and Dynamic Bandwidth Management)
The USG optimizes bandwidth by limiting bandwidth usage symmetrically or
asymmetrically on a per device (MAC address / User) basis, and manages the WAN
Link traffic to provide complete bandwidth management over the entire network.
With the ICC feature enabled, subscribers can increase or decrease their own
bandwidth dynamically (by the minute, or on an hourly, daily, weekly, or monthly
basis), and also adjust the pricing plan for their service.

Nomadix Enterprise MIB
The USG can be easily managed over the Internet with an SNMP client manager (for
example, HP OpenView or Castle Rock SNMPc). Simply import the nomadix.mib file
from the Accessories CD (supplied with the product) to view and manage SNMP
objects on your USG.
See also, “Installing the Nomadix Enterprise MIB” on page 52.
Introduction

UNIVERSAL SUBSCRIBER GATEWAY™
Remote Administration
Once installed and configured, the USG can be managed and administered remotely
with any of the following interfaces:
!
!
!
Web Management Server – providing a powerful and flexible Web
interface for network administrators. All USG models have an embedded
(internal) Web Management Server.
SNMP – allowing remote management using standard networking tools (for
example, HP OpenView).
Telnet – for simple remote management.
"
You cannot use these remote management tools (Web, SNMP, or Telnet)
if you are on the subscriber side of the USG.
License Key Server
The USG can interface with a Nomadix License Key Server which distributes
Nomadix license keys over the Internet. This functionality provides a simple method
for customers to obtain license keys and eliminates the need for system administrators
to input license keys manually.
Secure Administration
The USG incorporates a master access control list that checks the source (IP address)
of administrator logins. A login is permitted only if a match is made with the master
list contained on the USG. If a match is not made, the login is denied, even if a correct
login name and password are supplied.
The access control list supports up to 50 (fifty) entries in the form of a specific IP
address or range of IP addresses.
Bridge Mode
This feature allows complete and unconditional access to devices. When Bridge Mode
is enabled, the USG is effectively transparent to the network in which it is located,
allowing clusters of switches (esp. Cisco Systems switch clusters) to be managed
using the STP (Spanning Tree Protocol), or any other algorithm/protocol. The USG
forwards any and all packets (except those addressed to the USG network interface).
The packets are unmodified and can be forwarded in both directions.
The Bridge Mode is a very useful feature when troubleshooting your entire network
as it allows administrators to effectively “remove” the USG from the network without
physically disconnecting the unit.

UNIVERSAL SUBSCRIBER GATEWAY™
The Management Interfaces (CLI and Web)
"
The USG supports various methods for managing the system remotely.
These include, an embedded graphical Web Management Interface
(WMI), an SNMP client, or Telnet. However, until the unit is installed
and running, system management is performed from the USG’s
embedded Command Line Interface (CLI) via a direct serial cable
connection. The CLI can also be accessed remotely.
Until the unit is installed on the customer’s network and a remote connection is
established, the Command Line Interface (CLI) is the administrator’s window to the
system. This is where you establish all the USG start-up configuration parameters,
depending on the customer’s network architecture.
The USG Menu is your starting point. From here, you access all the system
administration items from the 5 (five) primary menus available “configuration,”
“network info,” “port-location,” “subscribers,” and “system.” The USG Menu also
includes a “logout” option for logging out of the system.
"
Although the basic functional elements are the same, the CLI and the
WMI have some minor content and organizational differences. For
example, in the WMI the “subscribers” menu is divided into
“Subscriber Administration” and “Subscriber Interface.” See also,
“Menu Organization (Web Management Interface)” on page 37.
Making Menu Selections and Inputting Data with the CLI
The Command Line Interface (CLI) is character-based. It recognizes the fewest
unique characters it needs to correctly identify an entry. For example, in the USG
Menu you need only enter c to access the Configuration menu, but you must enter su
to access the Subscribers menu and sy to access the System menu (because they both
start with the letter “s”).
You may also do any of the following:
!
!
!
!
Enter b (back) or press Esc (escape) to return to a previous menu.
Press Esc to abort an action at any time.
Press Enter to redisplay the current menu.
Press ? at any time to access the CLI’s Help screen.
When using the CLI, if a procedure asks you to “enter sn,” this means you must type
sn and press the Enter key. The system does not accept data or commands until you
hit the Enter key.

Installing the USG
UNIVERSAL SUBSCRIBER GATEWAY™
Establishing the Start Up Configuration
The Command Line Interface (CLI) allows you to administer the USG’s start-up
configuration settings.
"
When establishing the start-up configuration for a new installation, you
are connected to the USG via a direct serial connection (you do not
have remote access capability because the USG is not yet configured or
connected to a network). At this point, the CLI is the only management
interface available to you. Once the installation is complete (see
“Installation Workflow” on page 33) and the system is successfully
configured, you will have the additional options of managing the USG
remotely from the system’s Web Management Interface, an SNMP client
manager of your choice, or a simple Telnet interface.
The start up configuration must be established before connecting the USG to a
customer’s network. The “start up” configuration settings include:
!
Assigning a Login Name and Password – You must assign a unique
manager login user name and password that enables you to administer and
manage the USG securely.
"
!
!
!
!
!
!
User names and passwords are case-sensitive.
Setting the SNMP Parameters – The SNMP (Simple Network
Management Protocol) parameters must be established before you can use
an SNMP client (for example, HP OpenView) to manage and monitor the
USG remotely.
Enabling the Logging Options – Servers must be assigned and set up if you
want to create system and AAA (billing) log files, and retrieve error
messages generated by the USG.
Assigning the Network Interface IP Address – This is the public IP
address that allows administrators and subscribers to see the USG on the
network. Use this address when you need to make a network connection with
the USG.
Assigning the Subscriber Interface IP Address – This is the IP address
that subscribers will see on the private side of the USG.
Assigning the Subnet Mask – The subnet mask defines the number of IP
addresses that are available on the routed subnet where the USG is located.
Assigning the Default Gateway IP Address – This is the IP address of the
router that the USG uses to transmit data to the Internet.

UNIVERSAL SUBSCRIBER GATEWAY™
Assigning Login User Names and Passwords
When you initially powered up the USG and logged in to the Management Interface,
the default login user name and password you used was “admin.” The USG allows
you to define 2 concurrent access levels to differentiate between managers and
operators, where managers are permitted read/write access and operators are
restricted to read access only. Once the logins have been assigned, managers have the
ability to perform all write commands (Submit, Reset, Reboot, Add, Delete, etc.), but
operators cannot change any system settings. When Administration Concurrency is
enabled, one manager and three operators can access the USG at any one time (the
default setting for this feature is “disabled”).
1.
Enter sy (system) at the USG Menu.
The System menu appears.
2.
Enter lo (login).
The system prompts you for the current login. If this is the first time you are
changing the login parameters since initializing the USG, the default login name
and password is “admin.”
"
3.
The system accepts up to 14 characters (any character type) for user
names and passwords. All user names and passwords are case-sensitive.
When prompted, confirm the current login parameters and enter new ones.
SAMPLE SCREEN RESPONSE

UNIVERSAL SUBSCRIBER GATEWAY™
Setting the SNMP Parameters (optional)
You can address the USG using an SNMP client manager (for example, HP
OpenView). SNMP is the standard protocol that regulates network management over
the Internet. To do this, you must set up the SNMP communities and identifiers. For
more information about SNMP, see “Using an SNMP Manager” on page 54.
"
If you want to use SNMP, you must manually turn on SNMP.
1.
Enter c (configuration) at the USG Menu. The Configuration menu appears.
2.
Enter sn (snmp).
3.
Enable the SNMP daemon, as required. The system displays any existing SNMP
contact information and prompts you to enter new information. If this is the first
time you have initialized the SNMP command since removing the USG from its
box, the system has no information to display (there are no defaults).
4.
Enter the SNMP parameters (communities and identifiers). The SNMP
parameters include your contact information, the get/set communities, and the IP
address of the trap recipient. Your SNMP manager needs this information to
enable network management over the Internet.
5.
If you enabled the SNMP daemon, you must reboot the system for your changes
to take effect. In this case, enter y (yes) to reboot your USG.

Enabling the Logging Options (recommended)
System logging creates log files and error messages generated at the system level.
AAA logging creates activity log files for the AAA (Authentication, Authorization,
and Accounting) functions. You can enable either of these options.
"
Although the AAA and billing logs can go to the same server, we
recommend that they have their own unique server ID number assigned
(between 0 and 7). When managing multiple properties, the properties
are identified in the log files by their IP addresses.
When system logging is enabled, the standard SYSLOG protocol (UDP) is used to
send all message logs generated by the USG to the specified server.
1.
Enter log (logging) at the Configuration menu.
The system displays the current logging status (enabled or disabled).
2.
Enable or disable the system and/or AAA logging options, as required.
If you enable either option, go to Step 3, otherwise logging is disabled and you
can terminate this procedure.
3.
Assign a valid ID number (0-7) to each server.
4.
Enter the IP addresses to identify the location of the system and AAA SYSLOG
servers on the network (the default for both is 0.0.0.0).
When logging is enabled, log files and error messages are sent to these servers
for future retrieval. To see sample reports, go to “Sample SYSLOG Report” on
page 197 and “Sample AAA Log” on page 196.

UNIVERSAL SUBSCRIBER GATEWAY™
Assigning the Location Information and IP Addresses
The “location” command in the Configuration menu establishes the USG’s location
settings, the network interface IP address, the subscriber interface IP address, the
subnet mask, and the default gateway IP address. All of these USG “location”
parameters must be set up as part of the system’s start up configuration (otherwise the
USG will not be “visible” on the network).
1.
Enter c (configuration) at the USG Menu.
The Configuration menu appears.
2.
Enter loc (set Location options).
The system displays the Company Name. If the name displayed is not correct (or
no name is entered), enter it now.
3.
When prompted, enter the company’s address (line by line - 6 lines).
4.
When prompted, enter a valid email address for this company.
The system now displays the current network interface IP address (the default
address is 10.0.0.10) and prompts you for a valid address. The network interface
IP address is the public IP address that allows administrators to see the USG on
the network. Use this address when you need to make a network connection with
the USG.
"
5.
The network interface and subscriber interface addresses must be on the
same subnet.
When prompted, enter a valid network interface IP address.
After assigning the network interface IP address, the system displays the current
subscriber interface IP address (the default is 10.0.0.11).The IP addresses from
subscribers that are on a subnet different from the USG (for example,
misconfigured) are translated by Nomadix’ Dynamic Address Translation (DAT)
patented technology to the Subscriber IP Address.
6.
Enter a valid subscriber interface IP address.
After assigning the subscriber interface IP address, the system displays the
current subnet mask (the default mask is 255.255.255.0). The subnet mask
defines the number of IP addresses that are available on the routed subnet where
the USG is located.
"
The subscriber interface acts as a multifunctional “translator.” For
example, if a subscriber’s computer is setup statically for a network with
a gateway address of 10.1.1.1, the USG emulates the gateway to
accommodate this subscriber while emulating other gateways to
accommodate other subscribers.

7.
Enter a valid subnet mask.
After assigning the subnet mask, the system displays the current default gateway
IP address (the factory default is 10.0.0.1). This is the IP address of the router
that the USG uses to transmit data to the Internet.
8.
Enter a valid default gateway IP address.

Connecting the USG to the Customer’s Network
Use this procedure to connect the USG to the customer’s network (after the start up
configuration parameters have been established).
1.
Choose an appropriate physical location that allows a minimum clearance of 4cm
either side of the unit (for adequate airflow).
The USG must be positioned within three (3) feet of the router (to accommodate
the green UTP patch cable supplied with the unit). If you are mounting the unit in
a rack, use the brackets and mounting screws supplied in the carton, otherwise
choose a stable surface and fix the four (4) self-adhesive rubber feet to the unit’s
underside. For maximum stability, position the rubber feet at the corners,
approximately 0.75” from the adjacent edges.
"
2.
The USG can be mounted in a rack with either the front panel or the
rear panel exposed at the front of the rack. For example, if you want
easy access to the ports, mount the USG in the rack with the rear panel
exposed. Allow 4cm clearance for adequate airflow.
Connect the green UTP patch cable (3 ft.) between the USG and the router, then
connect the blue UTP patch cable (7 ft.) between the USG and the customer’s
subscriber port.

Go to “Establishing the Basic Configuration for Subscribers” on page 47.
Installing the USG
UNIVERSAL SUBSCRIBER GATEWAY™
Establishing the Basic Configuration for Subscribers
When you have successfully established the start up configuration and installed the
unit onto the customer’s network, connect to the USG via Telnet. You must now set
up the basic configuration parameters for subscribers, including:
!
!
Setting the DHCP Options – DHCP (Dynamic Host Configuration
Protocol) allows you to assign IP addresses automatically (to subscribers
who are DHCP enabled). The USG can “relay” the service through an
external DHCP server or it can be configured to act as its own DHCP server.
Setting the DNS Options – DNS (Domain Name System) allows
subscribers to enter meaningful URLs into their browsers (instead of
complicated numeric IP addresses). DNS converts the URLs into the correct
IP addresses automatically.
Setting the DHCP Options
When a device connects to the network, the DHCP server assigns it a “dynamic” IP
address for the duration of the session. Most users have DHCP capability on their
computer. To enable this service on the USG, you can either enable the DHCP relay
(routed to an external DHCP server IP address), or you can enable the USG to act as
its own DHCP server. In both cases, DHCP functionality is necessary if you want to
automatically assign IP addresses to subscribers.
"
1.
The USG’s adaptive configuration technology provides Dynamic
Address Translation (DAT) functionality. DAT is automatically
configured to facilitate “plug-and-play” access to subscribers who are
misconfigured with static (permanent) IP addresses, or subscribers that
do not have DHCP capability on their computers. DAT allows all users
to obtain network access, regardless of their computer’s network
settings.
Enter c (configuration) at the USG Menu.
The Configuration menu appears.
2.
Enter dh (dhcp).
The system displays the current status of the DHCP relay. The default is
“disabled.”
"
By default, the USG is configured to act as its own DHCP server and the
relay feature is “disabled.” If you want the USG to act as its own DHCP
server, do not enable the relay. Simply press “Enter” and go directly to
Step 5 (skip Steps 3 and 4).
Installing the USG
47
UNIVERSAL SUBSCRIBER GATEWAY™
3.
To route DHCP through an external server, enable the DHCP relay and assign a
valid IP address for the external DHCP server (the default is 0.0.0.0).
#
When assigning an IP address for the DHCP Relay, ensure that the IP
address you use does not conflict with devices on the network side of the
USG.
"
Please verify that your DHCP Server supports DHCP relay packets
before enabling this feature. Not all devices containing DHCP servers
(for example, routers) support DHCP Relay.
After assigning the IP address, you are prompted to reboot the system. You
should ignore this request because you will be rebooting the system after setting
up the DNS options (next procedure).

“disable” both functions from the Command Line Interface. In this
case, a warning message informs you that no DHCP services are
available to subscribers.

System Administration
2
This chapter provides all the instructions and procedures necessary for system
administrators to manage the USG on the customer’s network (after a successful
installation).
The system administration procedures in this chapter are organized as they are listed
under their respective Web Management Interface (WMI) menus (Configuration,
Network Info, Port-Location, Subscriber Administration, Subscriber Interface, and
System).
"
Now that the USG has been installed and configured successfully, this
User’s Guide moves away from the Command Line Interface (CLI) and
documents the USG from the Web Management Interface (WMI)
viewpoint.
Choosing a Remote Connection
Once installed and configured for the customer’s network, the USG can be managed
and administered remotely with any of the following interface options:
!
!
!
Embedded Web Management Server – providing a powerful and flexible
Web interface for network administrators.
SNMP Manager – allowing remote “Windows” management using an
SNMP client manager (for example, HP OpenView). However, before you
can use SNMP to access the USG, you must set up the appropriate SNMP
communities. For more information, refer to “Managing the SNMP
Communities {SNMP}” on page 95.
Telnet Client – for “character-based” administration and management,
using the Command Line Interface (CLI).
"
To use any of the remote connections (Web, SNMP, or Telnet), the
network interface IP address for the USG must be established (you did
this during the installation process).
Choose an interface connection, based on your preference.
System Administration
53
UNIVERSAL SUBSCRIBER GATEWAY™
Using the Web Management Interface (WMI)
The Web Management Interface (WMI) is a “graphical” version of the Command
Line Interface, comprised of HTML files. The HTML files are embedded in the USG
and are dynamically linked to the system’s functional command sets. You can access
the WMI from any Web browser.
To connect to the Web Management Interface, do the following:
1.
Establish a connection to the Internet.
2.
Open your Web browser.
3.
Enter the network interface IP address of the USG (set up during the installation
process).
4.
Log in as usual (supplying your user name and password).
To access any menu item from the WMI, simply click on the item you want. The
corresponding work screen then appears in the right side frame. From here you can
control the features and settings related to your selection. Although the appearance is
very different from the Command Line Interface, the information displayed to you is
basically the same. The only difference between the two interfaces is in the method
used for making selections and applying your changes (selections are checkable
boxes, and applying your changes is achieved by pressing the Submit button).
Pressing the Reset button resets the screen to its previous state (clearing all your
changes without applying them).
Using an SNMP Manager
Once the SNMP communities are established, you can connect to the USG via the
Internet using an SNMP client manager (for example, HP OpenView). SNMP is the
standard protocol used in the Network Management (NM) system. This system
contains two primary elements:
!
!
Manager – The console (client) through which system administrators
perform network management functions.
Agent – An SNMP-compliant device which stores data about itself in a
Management Information Base (MIB). The USG is an example of such a
device.
The USG contains managed objects that directly relate to its current operational state.
These objects include hardware configuration parameters and performance statistics.
Managed objects are arranged into a virtual information database, called a
Management Information Base (MIB). SNMP enables managers and agents to
communicate with each other for the purpose of accessing these MIBs and retrieving
data. See also, “Installing the Nomadix Enterprise MIB” on page 52.

System Administration
UNIVERSAL SUBSCRIBER GATEWAY™
The following example shows a (partial) SNMP screen response.
Using a Telnet Client
There are many Telnet clients that you can use to connect with the USG. Using Telnet
provides a simple terminal emulation that allows you to see and interact with the
USG’s Command Line Interface (as if you were connected via the serial interface).
As with any remote connection, the network interface IP address for the USG must be
established (you did this during the installation process).
Logging In
To access the USG’s Web Management Interface, use the manager or operator login
user name and password you defined during the installation process (refer to
“Assigning Login User Names and Passwords” on page 40).
"
User names and passwords are case-sensitive.

Defining the AAA Services {AAA}
This procedure shows you how to set up the AAA (Authentication, Authorization,
and Accounting) service options. AAA Services are used by the USG to authenticate,
authorize, and subsequently bill subscribers for their use of the customer’s network.
The USG currently supports several AAA models which are discussed in “Subscriber
Management” on page 178.

Enable or disable AAA Services.
If you enable AAA Services, go to Step 3, otherwise this feature is disabled and
you can exit the procedure.
3.
Enable or disable the XML Interface, as required.
XML (eXtensible Markup Language) is used by the USG’s subscriber
management module for port location and user administration. Enabling the
XML interface allows the USG to accept and process XML commands from an
external source. XML commands are appended to a URL in the form of an
encoded query string. The USG parses the query string, executes the commands
specified by the string, and returns data to the system that initiated the command
request.
4.
If you enabled the XML Interface feature, enter the XML IP (server) address.
5.
Enable or disable Print Billing Command, as required (this is an optional
feature, only available if the corresponding software package is purchased). If
this feature is enabled, you must enable the XML interface and enter the IP
address for the XML interface.
6.
Enable or disable the AAA Passthrough Port feature, as required.
System administrators can set the USG to pass-through HTTPS traffic, in
addition to standard port 80 traffic, without being redirected. When access to a
non-HTTPS address (for example, search engine) has been requested, the
subscriber is then redirected as usual.
System Administration

UNIVERSAL SUBSCRIBER GATEWAY™
7.
If AAA passthrough is enabled, enter the corresponding port number.
"
8.
The port number must be different than 80, 2111, 1111, or 1112.
Enable or disable the 802.1x Authentication Support feature, as required (your
license key must support this feature).
"
Support for 802.1x authentication requires both AAA and RADIUS
functions to be enabled.
When the USG is enabled with 802.1x, the USG becomes the authenticator in
the 802.1x enabled network. The USG’s advanced security feature enables the
support of a wide variety of authentication methods within the network.
"
9.
The USG contains advanced Dual Mode 802.1x/UAM functionality that
allows for the simultaneous use of both authentication methods without
any delay times. Go to “Contact Information” on page 225 and contact
nomadix technical Support for more information.

sections in this procedure:
!
!
58
Enabling AAA Services with the Internal Web Server – The IWS is
“flashed” into the system’s memory and the subscriber’s login page is served
directly from the USG. In this mode, the login page consists of a simple
request for the subscriber’s ID (user name) and password.
Enabling AAA Services with an External Web Server – In the EWS
mode, the USG redirects the subscriber’s login request to an external server
(transparent to the subscriber). The login page served by the EWS reflects
the “look and feel” of the solution provider’s network and presents more
login options.
System Administration
UNIVERSAL SUBSCRIBER GATEWAY™
Enabling AAA Services with the Internal Web Server
You are here because you want to enable the AAA Services with the USG’s Internal
Web Server. The USG maintains an internal database of authorized subscribers, based
on their MAC (hardware address) and user name (if enabled). By referring to its
database record, also known as an authorization table, the USG instantly recognizes
new subscribers on the network.
You can configure the USG to handle new subscribers in various ways (see the table
on this page). With the IWS, you also have the option of enabling SSL support (if
your license includes the SSL support feature and you have the certificate files
server.pem and cakey.pem on the flash).
After selecting the Internal Web Server authorization mode, you have the option of
enabling or disabling the Usernames and New Subscribers features. These features
work in conjunction with each other to determine how new subscribers are handled.
Refer to the following table:
Usernames

UNIVERSAL SUBSCRIBER GATEWAY™
SSL support allows for the creation of an end-to-end encrypted link between the
USG and its clients by enabling the Internal Web Server (IWS) to display pages
under a secure link—important when transmitting AAA information in a
network (especially when using RADIUS). Adding SSL support to the USG
requires service providers to obtain digital certificates from VeriSign™ to create
HTTPS pages. Instructions for obtaining certificates are provided by Nomadix.
"
To enable SSL Support, your product license must include this feature
and your USG’s flash must include the server.pem, cakey.pem, and
cacert.pem certificate files (the “cacert.pem” file is provided with your
USG). For assistance, contact “Technical Support” on page 231.
"
You must reboot the USG every time you enable or disable SSL support.
3.
If you want to designate a portal page, you must enable the Portal Page feature,
otherwise leave this feature disabled.
4.
If the “Portal Page” feature is enabled, enter the Portal Page URL. This is the
portal page that subscribers are redirected to.
"
You must add the Portal Page IP or DNS address to the IP passthrough
list and enable the IP passthrough function in the USG.
The USG contains a comprehensive HTTP page redirection logic that allows for
a page redirect before (also known as, Portal Page Redirect) and/or after the
authentication process (also known as, Home Page Redirect). As part of the
Portal Page Redirect feature, the USG can send a defined set of parameters to the
portal page redirection logic that allows an External web Server to perform a
redirection based on VLAN ID, subscriber MAC address, and an externally
hosted RADIUS login failure page. This means that the network administrator
can now perform location-specific service branding (for example, an airport
lounge) from a centralized Web server.

Enable or disable the Usernames feature, as required (refer to table on page 59).
Some subscribers may want additional account flexibility and security for their
services (for example, if they use more than one computer and their MAC
address changes, or if they move between port-locations). In this case, a
subscriber can define a unique user name and password which they can use from
any machine or location (without being re-charged). Subscribers who choose this
option are prompted for their user name and password whenever they try to
access the Internet. Solution providers can charge a fee for this service.
The “Usernames” function must be enabled for a RADIUS login.
9.
Enable or disable the New Subscribers feature (refer to table on page 59).
"
New Subscribers must be enabled before enabling the Credit Card
Service (only subscribers who are new to the system and who elect to
pay for their access time using a credit card will be authenticated by the
Credit Card Server).
10. Enable or disable the Relogin After Timeout feature, as required.
11. The system now prompts you to enable or disable the Credit Card Service. When
this feature is enabled, subscribers are prompted for their credit card information
(for billing purposes). The USG is configured to use either Authorize.net or
Chainfusion (selected from a pull-down menu). You will need to open a
merchant account with Authorize.net or Chainfusion before this feature can be
used.

Establishing Secure Administration {Access Control}
The USG incorporates a master access control list that checks the source (IP address)
of administrator logins. A login is permitted only if a match is made with the master
list contained on the USG. If a match is not made, the login is denied, even if a correct
login name and password are supplied. The access control list supports up to 50 (fifty)
entries in the form of a specific IP address or ranges of IP addresses.
This procedure allows you to enable the “Access Control” feature and to add or

Establishing Billing Records “Mirroring” {Bill Record Mirroring}
Your product license may not include this feature.
The USG can send copies of credit card and Property Management System (PMS)
transaction billing records to external servers that have been previously defined by
system administrators. The USG assumes control of billing transmissions and saving
billing records. By “mirroring” the billing data, the USG can also send copies of
billing records to predefined “carbon copy” servers. Additionally, if the primary and
secondary servers are down, the USG can store up to 2,000 PMS or credit card
transaction records. When a connection is re-established (with either server), the USG
sends the stored information to the server—no records are lost!

Managing the DHCP Service Options {DHCP}
When a device connects to the network, the DHCP server assigns it a “dynamic” IP
address for the duration of the session. Most users have DHCP capability on their
computer. To enable this service on the USG, you can either enable the DHCP relay
(routed to an external DHCP server IP address), or you can enable the USG to act as
its own DHCP server. In both cases, DHCP functionality is necessary if you want to
automatically assign IP addresses to subscribers.
1.
From the Web Management Interface, click on Configuration, then DHCP.
The DHCP Settings screen appears:
System Administration

UNIVERSAL SUBSCRIBER GATEWAY™
"
2.
DHCP Services is enabled by default. Do not disable it unless you want to lose
all your DHCP services.
"
3.
Nomadix’ patented Dynamic Address Translation (DAT) functionality is
automatically configured to facilitate “plug-and-play” access to
subscribers who are misconfigured with static (permanent) IP
addresses, or subscribers that do not have DHCP capability on their
computers. DAT allows all users to obtain network access, regardless of
their computer’s network settings.
By default, the USG is configured to act as its own DHCP server and the
relay feature is “disabled.” If you want the USG to act as its own DHCP
server, do not enable the relay. Go directly to Step 8.
If required, enable the IP Upsell feature (see note).
"
Your product license may not include this feature.
System administrators can set two different DHCP pools for the same physical
LAN. When DHCP subscribers select a service plan with a public pool address,
the USG associates their MAC address with their public IP address for the
duration of the service level agreement. The opposite is true if they select a plan
with a private pool address. This feature enables a competitive solution and is an
instant revenue generator for ISPs. The IP Upsell functionality solves a number
of connectivity problems, especially with regard to L2TP, IP Sec, and certain
video conferencing and online gaming applications.
Example: The most common setting for the IP Upsell feature is to set up the
DHCP Relay Server to give out “public” IP addresses, and the USG DHCP
Server to give out “private” IP addresses. In order to use the IP Upsell feature,
you must enable IP Upsell, DHCP Relay, and DHCP Server together.
4.
To route DHCP through an external server, enable the DHCP Relay.
5.
Select Public Pool or Private Pool, as required.
"
70
A “public” IP address is an address from the IP pool that is on the same
subnet as the USG’s network IP address.
System Administration
UNIVERSAL SUBSCRIBER GATEWAY™
6.
Assign a valid DHCP Server IP address (the default is 0.0.0.0) and a valid DHCP
Relay Agent IP address.
The DHCP Relay Agent allows the USG to request a specific range of IP
addresses from different IP pools from the DHCP Server. Leaving these fields
blank forces the system to use the IP pool that contains IP addresses that are on
the same subnet as the USG.
7.
"
You must disable the DHCP server before enabling the DHCP relay.
Both features cannot be enabled concurrently (unless the IP Upsell
feature is enabled).
#
If the DHCP Relay Agent IP address is set for an address that is already
used or the IP address of the server, the other system will get an IP
conflict and will not have internet access.
After assigning the IP address for the DHCP Relay and the DHCP Relay Agent,
you must reboot the system for the new settings to take effect. Click the check
box for Reboot after changes are saved? to save your changes and reboot the
system, or click on the Reset button if you want to reset all the values to their
previous state.
When the system restarts, the DHCP relay functionality is enabled and
configured. Skip the remaining steps in this procedure and go to “Managing the
DNS Options {DNS}” on page 72.
8.
You are at this step because you want the USG to act as its own DHCP Server

Assigning Passthrough Addresses (Passthrough Addresses)
The USG allows up to 300 (hundred) IP passthrough addresses and DNS names. This
feature allows users to “pass through” the USG and access predetermined services
(for example, the redirected home page) at the solution provider’s discretion, even
though they may not have subscribed to the broadband Internet service. This is useful
if solution providers want to openly promote selected services to all users, even if
they are not currently subscribing (paying) for access. Allowing up to 300
passthroughs (IP and DNS) offers customers greater promotional flexibility.

Assigning a PMS Service {PMS}
Your product license may not include this feature.
The USG can be integrated with existing Property Management Systems. For
example, by integrating with a hotel’s PMS, the USG can post charges for Internet
access directly to a guest’s hotel bill. In this case, the guest is billed only once. The
USG outputs a call accounting record to the PMS system whenever a subscriber
purchases Internet service and decides to post the charges to their room. The USG is
equipped with a dedicated PMS port to facilitate connectivity with a customer’s
Property Management System. For the hospitality environment, the following
additional PMS protocols are available:
!
Fidelio, PTI, and Holodex
"
Some Property Management Systems may require you to obtain a
license before integrating the PMS with the USG. Check with the PMS
vendor.
"
Some Property Management Systems may use interfaces that are
incompatible with the USG. If your USG is having trouble
communicating with a solution provider’s PMS, please contact technical
support. Refer to “Technical Support” on page 231.
Before you can change the PMS settings, a PMS must be connected to the USG via
the dedicated PMS serial port on the rear panel. See also, “Connecting the USG to the
Customer’s Network” on page 46.
The USG can query most popular Property Management Systems for confirmation of
the “names” and “room numbers” of hotel guests—effectively becoming a “clone” of
a popular Micros POS system. This functionality allows hotels to seamlessly deploy
wireless networks (or alternatively use low-cost wired access concentration
equipment) that either do not support port-ID or do so in a proprietary format that
Nomadix does not currently support—and still be able to bill directly to the room.

Defining the RADIUS Options {RADIUS Options}
Your product license may not include this feature.
With the appropriate product license, the USG supports Remote Authentication DialIn User Service (RADIUS). RADIUS is an authentication and accounting system
used by many Internet Service Providers (ISPs).
"
The “Usernames” function must be enabled for a RADIUS login. See
also, “Defining the AAA Services {AAA}” on page 56.
RADIUS enables ISPs to maintain a very large central database of users. By using
RADIUS, service providers can implement policy-based management of their
subscriber base. RADIUS also helps ISPs to collect statistical data about their
networks (for example, the amount of time users spend online).
By integrating RADIUS with the USG platform, ISPs can now store in the RADIUS
database the bandwidth each subscriber is allocated. For example, when a subscriber
logs in, the RADIUS server will send the USG the bandwidth parameters and the
USG will obey them. If a subscriber wants a faster bandwidth, they can simply go to
their ISP’s home page, select the new service, and log in again. In this event, the ISP
can collect the data provided by the subscriber’s input and update the subscriber’s
RADIUS record. Whenever the subscriber logs in, RADIUS informs the USG of the
subscriber’s new parameters.
The USG’s RADIUS functionality also includes an accounting feature that allows the
USG to post “accounting start” and “accounting stop” records to the RADIUS server.
ISPs can use these records to accurately track the usage on their networks.
Some of the key benefits of supporting RADIUS include:
!
!
!
!
!
Minimal administrator setup tasks
No human intervention
No technical support calls to effect changes
Subscribers can control their own level of service
Allows ISPs to track the usage on their networks
With the RADIUS Portal Redirect feature, the USG can receive a Nomadix VSA
from the RADIUS server for URL redirection, and provide a method for users to be
redirected to a different site when logging in, based on a predefined RADIUS
attribute.
For more information about RADIUS attributes, go to “RADIUS Attributes” on
page 199.

If you enabled the RADIUS interface, you must provide additional information
that is directly related to the RADIUS functionality. The system requires
parameters for the following categories:
!
!
!
!
!
Authentication – This category requires input for enabling RADIUS
authentication and automatic subscriber reauthentication, and requires
you to define IP addresses, ports, and secret keys for the primary and
secondary RADIUS servers (the secondary server is optional).
Accounting – This category requires input for enabling the RADIUS
accounting service, and also requires the necessary IP addresses, ports
and secret keys for the primary and secondary RADIUS accounting
servers. The RADIUS accounting server is responsible for receiving
accounting requests and returning a response to the client indicating that
it has received the request.
Retransmission Options – This category requires you to define the
data retransmission method (failover or round-robin), the retransmission
frequency, and how many retransmissions the system should attempt.
ISP Account Creation – This category defines the ISP account
parameters, including the URLs for the ISP portal Web page and the
account creation Web page, and the ISP server IP address.
Miscellaneous Options – This category requires an idle timeout
parameter and information related to a Network Access Server (NAS).
With the RADIUS client/server model, the NAS functions as a client of
the RADIUS accounting server. The NAS is responsible for passing
user accounting information to the accounting server.
Authentication
3.
If you enabled RADIUS authentication, click on the check box for Enable
Automatic Subscriber Reauthentication.
When “Enable Automatic Subscriber Reauthentication” is enabled, each time a
subscriber is successfully authenticated via RADIUS they are added to a special
file on the USG (not the standard authorization file). If an entry in the USG’s
memory table is deleted, instead of prompting the affected subscriber for their
user name and password, the USG looks up the special file and sends a request to
the RADIUS server with the subscriber’s user name and password stored in the
file (without prompting the subscriber). See note.
"
Because usernames/passwords are stored as text on the USG, use the
USG’s “Access Control” feature (page 63) or disable this function if
you cannot guarantee security on the USG.

Updating a Port-Location Assignment
The procedure for updating a port-location assignment is similar to adding a portlocation assignment. The difference between the two procedures is how they are
presented to you. For example, if you already have port-locations assigned and you
enter an existing “port” value, each data field that you go through (port, location,
state, and description) displays the value currently assigned to the field.
To update a Port-Location assignment, simply update the fields with new values.
"
110
If you have updated a port-location assignment, you may want to
change its description to distinguish from the old assignment. Although
the old assignment will no longer exist in the system, a meaningful
description can often be a valuable quick reference guide.

Enabling the Bridge Mode Option {Bridge Mode}
Bridge Mode allows complete and unconditional access to devices on the subscriber
side of the USG. When the Bridge Mode option is enabled, the USG is effectively
transparent to the network in which it is located, allowing clusters of switches
(especially Cisco Systems switch clusters) to be managed using the STP (Spanning
Tree Protocol), or any other algorithm/protocol. The USG forwards any and all
packets (except those addressed to the USG network interface). The packets are
unmodified and can be forwarded in both directions. This is a very useful feature
when troubleshooting your entire network as it allows administrators to effectively
“remove” the USG from the network without physically disconnecting the unit.
You can still manage the USG when Bridge Mode is enabled, but you have no other
functionality. If you enable the Bridge Mode option and then plug the USG into a
network, all you need to do is assign it routable IP addresses. You can then set up all
other features and disable the Bridge Mode option whenever you want to start using
the USG in that network.

This procedure shows you how to assign differentiated access levels for operators and
managers at login, and manager login control for remote RADIUS testing (if
RADIUS is enabled).
The USG allows you to define 2 concurrent access levels to differentiate between
managers and operators, where managers are permitted read/write access and
operators are restricted to read access only. Once the logins have been assigned,
managers have the ability to perform all write commands (Submit, Reset, Reboot,
Add, Delete, etc.), but operators cannot change any system settings. When this feature

This chapter provides an overview and a sample scenario for the USG’s Subscriber
Interface. It also includes a section outlining the authorization and billing processes
utilized by the system, and a section on the Information and Control Console (ICC).
Overview
The Subscriber Interface is the window to the solution provider’s Web site, and much
more than that. When a subscriber accesses the solution provider’s high speed
network, the USG points their browser to a sign-in page. The USG then creates a
database entry that automatically records the subscriber’s Media Access Control
(MAC) address and integrates this address with an external credit card authorization
system for secure billing. Like a router, the USG continuously tracks subscriber IP
and MAC settings, eliminating the need for further sign-ins and ensuring that
subscriber usage and billing is recorded accurately. The USG also eliminates
configuration issues between the subscriber’s computer and the network.
The Subscriber Interface is the portal Web site of the solution provider’s broadband
network, and as such, its appearance and functionality reflect the needs of the solution
provider. The USG is a gateway to this network, providing connection services that
enable and automate an effective Enterprise relationship between a supplier (the
solution provider) and its customer (the subscriber). The USG’s role in this customer/
supplier relationship is effectively “invisible” to subscribers.

A Subscriber Interface Scenario
The following scenario assumes that the USG is connected to a hotel’s broadband
network and is set up to use an external Web server. The screens illustrated in this
scenario are samples only, but they reflect the features and functionality of a typical
solution provider.
The Subscriber’s Experience
You have checked into the Malibu Hotel. You are in town to attend a convention and
you have your laptop computer with you. In your hotel room, you notice an RJ45 jack
and see a notice that the hotel offers high speed Internet access to its guests. You want
to get online immediately, so you plug in and launch your browser. You are presented
with the solution provider’s portal page:

You are now authorized and will find that you have full high speed access to the
Internet, as well as all the other services shown on the solution provider’s portal page.
The Subscriber Interface
173
UNIVERSAL SUBSCRIBER GATEWAY™
Authorization and Billing
As a gateway device, the USG enables plug-and-play access to broadband networks.
Broadband network solution providers can now offer their subscribers a wide range of
high speed services, including access to the Internet. Of course, a high speed Internet
connection is not free – subscribers pay an access fee, based on the duration of their
connection. Additionally, subscribers may want to take advantage of the solution
provider’s local network services (for example, purchasing goods and local services).
In either case, the subscriber is required to pay. And naturally, subscribers expect to
pay only for the services rendered to them.
In any environment, billing is a complex process. It requires accurate data collection
and reconciliation, a means to validate and protect the data, and an efficient method
for collecting payments.
The USG offers powerful billing support functionality called “Authentication,
Authorization, and Accounting.” This feature (also known as AAA) employs a
combination of command routines designed to create a flexible, efficient, and secure
billing environment. For example, when a subscriber logs into the system, their
unique MAC address is placed into an authorization table. The system then
authenticates the subscriber’s MAC address and billing information before allowing
them to access the Internet and make online purchases.

The AAA Structure
The USG’s Authentication, Authorization, and Accounting (AAA) module enables
the solution provider to provision, track, and bill new or returning subscribers. This
includes:
!
!
Allowing the solution provider (for example, a hotel) to bill its guests for the
high speed network services it provides, track usage on the network, and
deny service to those guests who have not paid.
Allowing the solution provider to bill subscribers for services rendered,
either directly on their hotel bill (in the hotel scenario), via a mailed invoice,
or directly to the subscriber’s credit card account.
The following illustration shows the functional relationship between the USG’s
internal modules and the external support systems.

The Authentication module is responsible for ensuring that when subscribers log in to
the system they are correctly identified. It can identify subscribers in many different
ways. For example:
!
!
!
!
Based on their hardware (MAC) address.
By validating their user name and password.
By looking up subscribers on a local (flash) database.
By looking up subscribers on a remote database (including RADIUS
servers).
"
The Authentication module can support user name and MAC address
authentication simultaneously.
The initial login page can be presented in various ways, depending on the system’s
configuration. The USG supports any of the following methods and tools:
!
!
!
!
!
Internal and external Web pages.
External “portal” page for redirection.
User name and MAC-based logins (simultaneous or stand-alone).
User-selectable options and parameters (for example, defining the time
purchased).
Interaction with a Property Management System (PMS) and Web interfaces
enabling administrators to edit the subscriber’s input.
Only subscribers that are correctly identified and authenticated are authorized to
access the system. Once authorized, the subscriber’s activity is logged and billed
through the USG’s Accounting module.
The Accounting module fully supports the following functions:
!
!
!
!
Credit card billing (for example, interaction with AuthorizeNet).
User name and password verification.
Billing verification.
Per port-location (for example, room or unit) billing.

Internal and External Web Servers
The USG supports both internal and external Web servers which act as a login
interface between subscribers and the solution provider’s network, including the
Internet. The internal Web server is “flashed” into the system’s memory and the login
page is served directly from the USG. In the external Web server model, the USG
redirects the subscriber’s login request to an external server. Either method is
transparent to the subscriber; however, the advantage of using the internal Web server
is obvious – no login redirection tasks and a faster response time for the subscriber.
Language Support
The USG’s subscriber interface supports many Asian and European languages,
including: English, Chinese, French, German, Japanese, and Spanish.
Home Page Redirection
The USG can be configured to redirect all valid subscribers to a Web portal or home
page determined by the solution provider. After a specified time, from the first home
page redirection (determined by the system administrator), subscribers are redirected
again to the portal at the next Web page request.
Subscriber Management
The USG provides several subscriber management models, including:
!
!
!
!
!
Free access (for example, no AAA functionality)
MAC address
Port-Location ID (for example, by room or unit number)
User name and password
Credit card
Combinations of two or more subscriber management models can be used. When a
subscriber connects to the network and attempts to access the Internet, the USG looks
for each model in the given order above.
178
The Subscriber Interface
UNIVERSAL SUBSCRIBER GATEWAY™
Subscriber Management Models
The system administrator establishes the subscriber management model via the
Command Line Interface (CLI) or the Web Management Interface. These models can
be changed while the USG is running (without rebooting or interrupting the service).
!
!
!
Free Access – If the USG is configured to disable AAA services, all
subscribers will have free access to the Internet.
MAC Address – Each computer with an Ethernet interface card has a
unique MAC (hardware) address. The USG can be configured to allow
access for specified MAC addresses. In this model, when a subscriber
attempts to access the Internet, the USG validates the subscriber’s MAC
address against a MAC authorization table. If the MAC address is verified,
the USG authorizes access to the Internet. A possible scenario for using this
model is to allow Internet access to administrative personnel in all locations.
Port-ID – If your DSLAM (DSL Access Multiplexor) or Ethernet switch
supports VLAN tagging or SNMP queries for port-location, then all network
ports in each location can be assigned a unique Port-ID. In this model, when
a subscriber attempts to access the Internet, the USG recognizes which
location the request originated from and generates the data necessary for that
location to be billed. For more information about port locations, go to
“Optional Standalone Applications” on page 27.
"
!
!
Even if your DSLAM or Ethernet switch does not support
VLAN tagging or SNMP queries for port-location, the USG has
the capability of “simulating” port locations by comparing its
MAC and Port-Location authorization tables through the AAA
Management Information Base (MIB).
User Name and Password – Each subscriber can choose a unique user
name and password (and be charged for it). In this model, when a subscriber
attempts to access the Internet, they are prompted for the user name and
password before access is authorized. Possible scenarios in which this model
is appropriate include allowing subscribers to use more than one computer,
when subscribers want to move between locations, or to integrate the service
with RADIUS (used by many Internet Service Providers).
Credit Card – In this model, when subscribers connect to the network and
attempt to access the Internet, they are prompted for their credit card
information. The USG is pre-configured to use the Authorize.Net service and
you will need to open a merchant trading account with them before using
this subscriber management model.

User Name and Password
Enable the AAA services and Usernames. Add a
subscriber profile to the database for each user name
and password you want to enable. You will need to
request a unique user name and password when they
pay for the service.
The user name and password are optional (the MAC
address will be substituted), but in this event the service
is not transferable between computers.
Credit card
Enable the AAA services. You have the choice of
enabling the USG’s internal authorization module or
using an external credit card authorization server.
Internal Authorization Enabled
Enter the credit card server’s URL and IP address, then
enter the merchant ID you obtain from Authorize.Net.
If you have NOT enabled Internal Authorization
Set up your own external authorization server with your
merchant ID. Enter the secret key (the default is
bigbrowndog). Enter the external authorization server’s
URL, then enter its IP address as a pass-through IP
address.

The Subscriber Interface
UNIVERSAL SUBSCRIBER GATEWAY™
Information and Control Console (ICC)
The Information and Control Console (ICC) is a JAVA™ pop-up window that is
presented to subscribers, allowing them to select their bandwidth and billing options
quickly and efficiently, and displays a dynamic “time” field to inform them of the
time remaining on their account. The ICC also offers service providers an opportunity
to display advertising banners and provide a choice of redirection options.
The ICC is optional. Your USG may not contain this feature.
For information about configuring the ICC, refer to “Setting Up the Information and
Control Console {ICC Setup}” on page 135.
ICC Pop-Up Window
The ICC displays a JAVA™ applet in the form of a pop-up window from which
subscribers can dynamically control their billing options and bandwidth, and which
allows service providers to display advertising banners and redirect their subscribers
to predetermined Web sites.

RADIUS Attributes
RADIUS (Remote Authentication Dial-In User Service) was originally created to
allow remote authentication to the dial-in networks of corporations and dial-up ISPs.
It is defined and standardized by the IETF (Internet Engineering Task Force) and
several RADIUS server packages exist in both the public domain and for commercial
sale.
RADIUS software stores a database of attributes about their valid subscriber base.
For example, usernames, passwords, access privileges, account limits and subscriber
attributes can all be stored in a RADIUS database. RADIUS works in conjunctions
with NAS (Network Access Server) devices to determine if access to the service
network should be granted, and if so, with what privileges.
All subscribers attempting to gain access to the
network are validated by RADIUS.
When a subscriber attempts to access the service provider's network, the USG
delivers a Web page to the subscriber asking for a login name and password. This
information (password) is encrypted and sent across the network to the ISP's
RADIUS server. The RADIUS server decrypts the information and compares it
against its list of valid users. If the subscriber can be authenticated, the RADIUS
server replies to the USG with a message instructing it to grant access to the
subscriber. Optionally, the RADIUS server can instruct the NAS to perform other
functions; for example, the RADIUS server can tell the USG what upstream and
downstream bandwidth the subscriber should receive. If RADIUS cannot authenticate
the subscriber, it will instruct the NAS to deny access to the network.
The Nomadix USG RADIUS functionality can be broken down into the following
categories:

Selected Detailed Descriptions
Acct-Session-ID
The Acct-Session-ID is created when the RADIUS authentication request is built. It is
transmitted in both the Access-Request and the Accounting-Request.
Session Timeout
There is currently no default session timeout settable in the USG Web Management
Interface (WMI). If the Radius server does not send a Session-Timeout, the USG will
set the subscriber expiration time to 0, which means access forever.
Quick Reference Guide
201
UNIVERSAL SUBSCRIBER GATEWAY™
Idle Timeout
The WMI allows the setting of a default timeout. If the Radius server does not send an
Idle-Timeout in the Radius Access-Accept, the USG will use the default one to
disconnect subscribers. "0" means forever.
Timeout Detection
If a subscriber is sending traffic through the USG, the USG will immediately detect a
Session-Timeout. However in the case of an Idle-Timeout or an inactive subscriber
Session-Timeout, the USG detects it via a clean-up function that is currently called
every 2 minutes. Thus the current precision for sending the Acct-Stop is about 2
minutes.
Subscriber Session Duration
Acct-Session-Time is calculated the following way (for each transmitted/
retransmitted Acct-Stop):
Acct-Session-Time = time of last sent packet - subscriber login time.
Another attribute, Acct-Delay-Time, will take into consideration the time spent in
retransmissions.
Interim Accounting Updates
The USG parses the attribute Acct-Interim-Interval in an Access-Accept. If this
attribute is present the USG tries every [Acct-Interim-Interval] seconds to send a
Radius Accounting Interim message for the specific subscriber. If this attribute is not
present or equal to 0, no Interim message is sent.
The precision is 2 minutes. The USG will not send Interim messages more frequently
than every 2 minutes.
Called-Station-ID
This is the Media Access Control (MAC) address of the USG.
Calling-Station-ID
This is the Media Access Control (MAC) address of the client's computer.
New Attributes in Acct-Request
The USG has to send the following attributes in an Accounting-Stop:
! Acct-Output-Packets: number of packets sent by subscriber.
! Acct-Input-Packets: number of packets received by subscriber.
Upon a reboot, these 2 attributes are saved in currfile.dat the same way as for AcctInput-Octets and Acct-Input-Octets.

Prerequisites
1.
You must purchase the SSL feature which is enabled through a license key from
Nomadix. If you did not purchase the SSL feature, the SSL option in the USG™
platform's Web Management Interface (WMI) will still be present, but you will
not able to enable the feature.
2.
You should be a business that is qualified to obtain an SSL secure server ID from
different Certificate Authorities (CAs), such as VeriSign. The Certificate
Authority sets this qualification criterion.
3.
You will need to generate your own Private Key and Certificate Signing Request
(these instructions are provided below).
4.
You must obtain your own Signed Public Key from the Certificate Authority.
The selected Certificate Authority should be commonly supported in the

Some older versions of popular browsers only support 40-bit or 56-bit
encryption. Since it impossible to forecast the browsers that may be
used in a visitor-based network, Nomadix recommends implementing a
40-bit Public Key.
During the process, VeriSign will ask for your business information and verification.
There are several ways to proof the existence of your business. Please follow the
instruction from VeriSign carefully. In addition, there is one section about generating
a CSR; however, since you have already created the CSR in step 2 with OpenSSL,
you can skip the instructions.

Mirroring Billing Records
Multiple USG units can send copies of credit card and Property Management System
(PMS) billing records to a number of external servers that have been previously
defined by system administrators. The USG assumes control of billing transmissions
and saving billing records. By effectively "mirroring" the billing data, the USG can
send copies of billing records to predefined "carbon copy" servers.
Additionally, if the primary and secondary servers are down, the USG can store up to
2,000 PMS or credit card transaction records. The USG regularly attempts to connect
with the primary and secondary servers. When a connection is re-established (with
either server), the USG sends the cached information to the server. Customers can be
confident that their billing information is secure and that no transaction records are
lost.
This document describes the process used by the Nomadix Universal Subscriber
Gateway for mirroring billing records, and is organized into the following sections:
! Sending billing records
! XML Interface
! Web Management Interface (WMI) configurations
216
Quick Reference Guide
UNIVERSAL SUBSCRIBER GATEWAY™
Sending Billing Records
When there is a message (billing record) in the message queue, the system "wakes up"
and performs the following tasks:
1.
Stores the billing record in the flash
2.
Create an XML packet, based on the new billing record
3.
Send the billing record to the carbon copy server(s)
4.
Transmit the data currently stored in the flash, based on the specified
retransmission method (round-robin: A-B-A-B, or fail-over: A-A-B-B)
The system stores the billing record in the flash so that the record will not be lost (for
example, if the USG™ is powered down during transmission attempts.
"
Billing records are sent to the carbon copy server(s) only after the
records are placed in the message queue. Carbon copy servers will not
receive the records again if a task for retransmitting to the primary or
secondary server needs to be performed.
XML Interface
XML for the External Server
The USG sends a string of XML commands according to specifications. HTTP
headers are added to the XML packets that are built, as the billing "mirroring"
information is sent to the external server in HTTP compliant XML format.
The XML string built from the billing mirror record is in the following format:
USG to External Server:
<USG RMTLOG_COMMAND="ADD_REC">
<REC_NUM>
<USG_ID>
<PROPERTY_ID>

This chapter provides information to help you resolve common hardware and
software problems. It also contains a list of known error messages associated with the
Management Interface.
General Hints and Tips
The USG is both a hardware device and a powerful software utility. As a hardware
computing device, the USG requires careful handling. It should be positioned in a
dust-free and temperature-controlled environment. Never block the unit’s ventilation
holes, and do not stack with other equipment (unless correctly mounted in a rack). If
you suspect the unit is overheating, check that the internal cooling fan is operating
correctly. The fan should run freely and silently at all times. The power cord and the
UTP patch cables must have an unrestricted path between the unit and their
destinations. Ensure that the RJ45 connectors are firmly located in their receptacles.
Applying these guidelines should ensure trouble-free operation.
Power Loss
Use this procedure if you unexpectedly lose power to the USG.
The power cord is firmly situated in the power socket on the rear panel.
YES NO
Plug in the power cord again and ensure that it is firmly situated in its
socket.
The solution provider’s power source is available.
YES NO
Inform the solution provider that the power source to the system has
failed.
Replace the fuse in the USG. See “Replacing the Fuse” on page 226.
Power is restored.
YES NO
Contact technical support. See “Technical Support” on page 231.
There is usually a reason why a fuse fails. When you power up the system,
check that the cooling fan is operating correctly. You should also check that
the system is adequately ventilated.

An IEEE standard for providing a virtual LAN capability within a campus network. 802.1Q establishes a
standard format for frame tagging (Layer 2 VLAN markings), enabling the creation of VLANs that use
equipment from multiple vendors.
10/100 Ethernet
See Ethernet.
AAA
(Authentication, Authorization, and Accounting) A combination of commands used by the USG to
authenticate, authorize, and subsequently bill subscribers for their use of the customer’s network. When a
subscriber logs into the system, their unique MAC address is placed into an authorization table. The system
then authenticates the subscriber’s MAC address and billing information before allowing them to access
the Internet and make online purchases. See also, MAC Address.
Access Concentrator
A type of multiplexor that combines multiple channels onto a single transmission medium in such a way
that all the individual channels can be simultaneously active. For example, ISPs use concentrators to
combine their dial-up modem connections onto faster T-1 lines that connect to the Internet. Concentrators
are also used in Local Area Networks (LANs) to combine transmissions from a cluster of nodes. In this
case, the concentrator is often called a hub.
Access Router
A router at a customer site, which connects to the network service provider. Also known as a Customer

ATM
(Asynchronous Transfer Mode) A network technology based on transferring data in “cells” or packets of a
fixed size (53 bytes each). The cell used with ATM is relatively small compared to units used with older
technologies. The small, constant cell size allows ATM equipment to transmit video, audio, and computer
data over the same network, and assures that no single type of data monopolizes the line. ATM can offer
multi-gigabit bandwidth. See also, Bandwidth and Packet.

Bandwidth
The maximum speed at which data can be transmitted between computers across a network, usually
measured in bits per second (bps). If you think of the communication path as a water pipe, the bandwidth
represents the width of the pipe which consequently determines how many gallons of water can flow
through it at any given time. See also, Broadband.
Broadband
A high speed data transmission medium capable of supporting a wide range of varying frequencies.
Broadband can carry multiple signals at fast rates of speed by dividing the total capacity of the medium into
multiple, independent bandwidth channels, where each channel operates only on a specific range of
frequencies. See also, Bandwidth.
CoS
(Class of Service) A category based on the type of user, type of application, or some other criteria that QoS
systems can use to provide differentiated classes of service. The characteristics of the CoS may be
appropriate for high throughput traffic, for traffic with a requirement for low latency, or simply for best
effort. The QoS experienced by a particular flow of traffic will be dependent on the number and type of
other traffic flows admitted to its class. See also, QoS.
Daemon
A program that runs continuously in the background, or is activated by a particular event (for example, an
error may trigger Syslog). The word daemon is Greek for “spirit” or “soul.” See also, SYSLOG.
DAT
(Dynamic Address Translation) The USG provides “plug-and-play” access to subscribers who are
misconfigured with static (permanent) IP addresses, or subscribers that do not have DHCP functionality on
their computers. DAT is a Nomadix, Inc. patented technology that allows all users to obtain network access,
regardless of their computer’s network settings. See also, DHCP.
DHCP
(Dynamic Host Configuration Protocol) A standard method for assigning IP addresses automatically to
devices connected on a TCP/IP network. When a new device connects to the network, the DHCP server
assigns an IP address from a list of its available addresses. The device retains this IP address for the
duration of the session. When the device disconnects from the network, the IP address becomes available
for reassignment to another device. See also, Dynamic IP Address, IP Address, Static IP Address, and TCP/
IP.
DNS
(Domain Name System) A system that maps meaningful domain names with complex numeric IP
addresses. See also, Domain Name and IP Address.
Domain Name
A unique and meaningful name representing each addressable computing device on a dynamic network (for
example, the Internet). Some devices have more than one domain name. When a user types a domain name,
requesting a connection to the device, DNS converts the domain name into a numeric IP address. The
location of the device on the network is known by its IP address. WWW.YAHOO.COM is an example of a
commercial domain name on the World Wide Web. See also, DNS, Internet, and IP Address.
Dynamic IP Address
A temporary IP address that is assigned by the DHCP server to a device. Devices retain dynamic IP
addresses only for the duration of their networking session. When a device disconnects from the network,
the IP address is recaptured by the DHCP server and becomes available for reassignment to another device.

IP Address
The numeric address of a device, in the format used on the Internet. The actual numeric value takes the
form of a 32-bit binary number broken up into four 8-bit groups, with each group separated by a period (for
example, 198.43.7.85). To make it easier for the user, the IP address is mapped to a meaningful domain
name. IP addresses can be static (permanent) or dynamic (assigned each time you connect). See also,
Domain Name, Dynamic IP Address, Internet Protocol, and Static IP Address.
IP Address Translation
The USG uses adaptive configuration technology which can accommodate all network configurations,
including dynamic and static IP address assignments. This enables it to solve IP addressing problems in
environments where the service provider does not have control over the subscriber’s network settings.
Whenever a subscriber logs on, the USG automatically translates their computer’s network settings to
provide them with seamless access to the broadband network. Subscribers no longer need to alter their
computer’s settings. See also, Dynamic IP Address, IP Address, and Static IP Address.

802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sub
layers – the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer
interfaces directly with the network media. Consequently, each type of network media requires a different
MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI
Reference Model, the node address is called the Data Link Control (DLC) address. See also, IEEE and

Mbps
(Megabits per second) A standard measure for data transmission speeds (for example, the rate at which
information travels over the Internet). 1 Mbps denotes one million bits per second. Several factors can
influence how quickly data travels, including modem speed, bandwidth capacity, and Internet traffic levels
at the time of transmission. Not to be confused with MegaBytes per second (MBps). See also, Throughput.
MIB
(Management Information Base) A set of parameters an SNMP management station can query or establish
in the SNMP agent of a network device (for example, a router). Standard minimal MIBs have been defined,
and vendors often have their own private enterprise MIBs. In theory, any SNMP manager can talk to any
SNMP agent with a properly defined MIB. See also, SNMP.
Misconfigured User
A Nomadix, Inc. term used to describe users who have IP address configurations that are different from the
current network. For example, if the current network is 123.45.67.89 but the user’s IP address is
10.10.10.15, then this user is considered to be “misconfigured.”
Multiplexor
A communications device that multiplexes (combines) several signals for transmission over a single
medium. A demultiplexor completes the process by separating multiplexed signals from a transmission
line. A multiplexor is sometimes called a MUX.
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 performs all the necessary IP address translations. NAT provides
a type of firewall by hiding its internal IP addresses. Additionally, NAT enables companies to use more
internal IP addresses (because the addresses are only used internally and there’s no possibility of
conflicting with IP addresses used by other companies). NAT also allows companies to combine multiple
ISDN connections into a single Internet connection. See also, ISDN.
Node
An addressable point on a network. A node can connect a computer system, a terminal, or various
peripheral devices to the network. Each node on a network has a distinct name. On the Internet, a node is a
host computer with a unique domain name and IP address. See also, Domain Name and IP Address.
OSPF
(Open Shortest Path First) This routing protocol was developed for IP networks based on the shortest path
first or link-state algorithm. Routers use link-state algorithms to send routing information to all nodes on a
network by calculating the shortest path to each node based on a topography of the Internet constructed by
each node. Routers send that portion of the routing table (keeping track of routes to particular network
destinations) that describes the state of its own links, and it also sends the complete routing structure
(topography). The advantage of shortest path first algorithms is that they result in smaller more frequent
updates everywhere. They converge quickly, thus preventing such problems as routing loops and count-toinfinity (when routers continuously increment the hop count to a particular network). This makes for a
stable network. The disadvantage of shortest path first algorithms is that they require a lot of CPU power
and memory to process them; however, the advantages significantly outweigh the disadvantages. OSPF
(version 2) is defined in RFC 1583 and is rapidly replacing RIP on the Internet as the preferred routing
protocol. See also, RFC, RIPv2 and Router.
Packet
How data is distributed over the Internet. A packet contains the source and destination addresses, as well as
the data. An ethernet packet is normally 1,518 bytes. In IP networks, packets are often called datagrams.

UNIVERSAL SUBSCRIBER GATEWAY™
Packet Switching Network
Refers to protocols in which messages are divided into packets before they are sent. Each packet is then
transmitted individually and can even follow different routes to its destination. Once all the packets
forming a message arrive at its destination, they are recompiled into the original message. Most modern
Wide Area Network (WAN) protocols, including TCP/IP, X.25, and Frame Relay, are based on packetswitching technologies. By contrast, normal telephone services use a circuit-switching technology in which
a dedicated line is allocated for transmission between two parties. Circuit-switching is ideal for fast data
transmissions where the data must arrive in the same order in which it is sent. This is the case with most
real-time data, such as live audio and video. Packet switching is more efficient and robust for data that can
withstand some delays in transmission, such as e-mail messages and Web pages. See also, Forwarding
Rate, Packet, pps, and Throughput.
PDF

Protocol). All these protocols are responsible for regulating the transmission of their specific data file
types.
QoS
(Quality of Service) A collective measure of the level of service delivered to the customer. QoS can be
characterized by several basic performance criteria, including availability (low downtime), error
performance, response time and throughput, lost calls or transmissions due to network congestion,
connection set-up time, and the speed of fault detection and correction. Service providers may guarantee a
particular level of QoS (defined by a service level agreement) to their subscribers. QoS-enabled hardware
and software solutions sort and classify IP packet requests into different traffic classes and allocate the
proper resources to direct traffic based on various criteria, including application type, user or application
ID, source or destination IP address, time of day, and other user-specified variables. See also, CoS and ToS.
RADIUS
(Remote Authentication Dial-In User Service) An authentication and accounting system used by many
Internet Service Providers (ISPs). When you dial in to the ISP you must enter your user name and
password. This information is passed to a RADIUS server, which checks that the information is correct,
and then authorizes access to the ISP system.
RFC
(Request for Comments) A series of notes about the Internet, started in 1969 (when the Internet was the
ARPANET). An RFC note can be submitted by anyone. Each RFC is designated by an RFC number. Once
published, an RFC never changes. Any modifications to an original RFC are assigned a new RFC number.
RIPv2
(Routing Information Protocol, version 2) A protocol defined by Request For Comments (RFC) 1058 that
specifies how routers exchange routing table information. With RIP, routers periodically exchange entire
tables. Because this approach can be inefficient, RIP is gradually being replaced by a newer routing
protocol called Open Shortest Path First (OSPF). See also, OSPF and Router.

Socket
A communication path between two computer programs, not necessarily running on the same machine.
Sockets are managed by a “socket device driver” that establishes network connections, as needed.
Programs that communicate through sockets need not know anything about how the network functions.
Solution
A hardware and/or software device that solves a customer’s problems. For example, the USG is a
subscriber gateway solution for broadband network service providers who want to integrate their high
speed services with the Internet and offer these services to their end users (subscribers). A “solution”
normally incorporates a suite of tools. See also, Solution Provider.
Solution Provider
Vendors are considered to be solution providers when they provide products and/or services that meet their
customer’s specific needs. Normally, a solution provider is offering a solution that isn’t readily available on
the open market. For example, NOMADIX™ is a solution provider to its customers (broadband network
service providers), and those customers are solution providers to their end users (network subscribers). See
also, Solution.
Static IP Address
An IP address that is assigned to a computing device permanently (or until the user changes it manually),
unlike a dynamic IP address which is assigned to a device temporarily by the DHCP server. See also,
DHCP, IP Address and Dynamic IP Address.
STP
(Spanning Tree Protocol) A link management protocol that is part of the IEEE 802.1 standard for media
access control bridges. Using the spanning tree algorithm, STP provides path redundancy while preventing
undesirable loops in a network that are created by multiple active paths between stations. Loops occur
when there are alternate routes between hosts. To establish path redundancy, STP creates a tree that spans
all of the switches in an extended network, forcing redundant paths into a standby (or blocked) state. STP
allows only one active path at a time between any two network devices (this prevents the loops) but
establishes the redundant links as a backup if the initial link should fail. If STP costs change, or if one
network segment in the STP becomes unreachable, the spanning tree algorithm reconfigures the spanning
tree topology and reestablishes the link by activating the standby path. Without spanning tree in place, it is
possible that both connections may be simultaneously “live,” which could result in an endless loop of
traffic on the LAN. See also, Loop.
Subnet
A portion of a network, which may be a physically independent network segment, which shares a network
address with other portions of the network and is distinguished by a unique subnet address. In general, a
subnet is to a network what a network is to the Internet.
Subnet Address
