OVERVIEW
The LPS-20xR is an outdoor/low profile span-powered Access Point (AP). The LPS-300C Central Office (CO) power
module provides span powering to the LPS-20x. Each LPS-300 can power two individual LPS-20xs. There are
currently two types of APs available: the LPS-20xR L1A Outdoor series and the LPS-20xR L1B Low Profile series
units.
Telco carriers in the Wireless Fidelity (Wi-Fi®) market can create a carrier class access point with the following
features:
• Span powering over symmetric or asymmetric, rate adaptive Digital Subscriber Loop (DSL) from any
Digital Subscriber Line Access Multiplexer (DSLAM) supporting xDSL transport
• Hardened outdoor packaging
• Roadmap support for class Quality of Service (QoS) in the Asynchronous Transfer Mode (ATM) DSL
backhaul
• Simple Network Management Protocol (SNMP) Management Information Base (MIB), allowing integration
into their management system
• Product family support for fatter pipe, NxDS1 backhaul
• Low first-cost deployment from remote cabinet DSLAM and Digital Loop Carrier (DLC) platforms
• NEBS and OSMINE compliant
Wi-Fi deployment fits into the overall DSLAM broadband services market. It allows Telco carriers to use their
existing infrastructure to easily be part of the public Wi-Fi arena. The LPS-20x is a simple end device that, with the
exception of the span powering, uses standards based interfaces. This permits it to be deployed directly from
existing DSLAM equipment without the need to introduce new CO ATM switching elements into the Telco carrier’s
network.
The two-wire dry xDSL interface from the DSLAM is routed through a power shelf co-located in the CO (Figure 1).
The LPS-300C located in the power shelf does not regenerate the xDSL signal; rather, it superimposes a Class A2,
DC powering voltage on the outside plant (OSP) interface. This is a standard xDSL signal since it comes from a
DSLAM. Therefore, there is no proprietary signal added to the stream.

DESCRIPTION
WI-FI CO-BASED DSLAM DEPLOYMENT
Using existing DSLAMs, a G.SHDSL or ADSL pair is routed to the LPS-300C power card in the HMS-318 power
shelf (Figure 2). The LPS-300C is a 3192 double-wide card that supports two powered xDSL pairs per module. A
total of 11 LPS-300C cards can be installed in the UL-60950 compliant HMS-318 power shelf for a total of 22
span-powered pairs. The LPS-300C, without affecting the xDSL signal, adds power to the span to operate the
LPS-20x.
The access point converts the ATM data coming in on the span and bridges it an Ethernet transparent bridge
broadcasting via 802.11b Wi-Fi standards to any client who has a wireless Network Interface Card (NIC).
The Access Controller forwards to the RADIUS Server authentication requests, then the RADIUS Server
authenticates the user. Once authenticated, the user has access to the internet. The Access Server tracks the
connection time for billing purposes. Some applications may include the replacement of pay phones with LPS-20xs
to create a wireless public hotspot.

G.SHDSL RATE/REACH
G.SHDSL is a symmetrical rate adaptive transport technology and ranges from 72 kb/s to 2.368 Mb/s in 64 kb/s
increments over a single twisted pair. The LPS-20x defaults to rate adaptive mode for best link speed. The range on
an unimpaired G.SHDSL cable is shown in Table 3. The G.SHDSL attenuation is less than 0.5 dB.

LPS-20X
The power function within the LPS-20x removes the line power provided by the LPS-300C and generates the DC
voltage for the LPS-20x functions (Figure 3). As shown in Figure 3, the power function is integrated with the xDSL
modem circuit board. The ATM function of the modem maps all users to a single Virtual Circuit (VC) with
Unspecified Bit Rate (UBR) services.

ANTENNA
The enclosure supports dual internal dipole antennas for diversity (Table 10). The LPS-20x always transmits on one
antenna. However, dual antennas allow diversity in the receive direction. Spatial diversity in the receive path
improves overall system performance by switching from one antenna to the other and selecting the antenna offering
the best receive signal. The access point electronics makes this selection. You have the option to attach one or two
external antennas via dual SMA connectors. One antenna is always used for transmission and reception. Therefore,
for single external antenna installations, make sure that the antenna intended as the transmit/receive antenna is
connected to the SMA connector labeled XMIT/RECEIVE.

INTRODUCTION TO THE WIRELESS ACCESS POINT
The LPS-20x wireless Access Point (AP) series are remote units that are designed to work in conjunction with
Remote Authenication Dial-In User Service (RADIUS) Servers, access controllers or similar products (Figure 10).
The role of the LPS-20x is to extend the wireless network and provide intelligent data forwarding to maintain the
security of the network.
The LPS-20xs are interconnected using a backbone LAN or are daisy-chained together. This makes it easy to add
more wireless coverage to service additional floor space or an increasing number of users.
Figure 10. LPS-20x
The LPS-20x provides wireless network coverage in a radius of up to 100 meters (300 feet). It uses radio waves in
the 2.4 Ghz band to communicate with client stations. To maintain the security of individual client stations on the
wireless network, the LPS-20x does not forward data between wireless client stations by default.
INTELLIGENT BRIDGE
Unlike a traditional bridge which automatically forwards all traffic between ports, the LPS-20x can apply security
filters to maintain the security of the network. When enabled, these filters essentially block all traffic that is not
addressed to or received from the access controller.

SERVICE SENSOR
The service sensor enables the LPS-20x to determine if access to the network or a particular server is available. If
not, the LPS-20x automatically shuts off its radio transmitter taking down the wireless cell. The service sensor polls
the target device approximately every half second. For more details, refer to Service Sensor on page 94.
ROAMING
Client computers are able to move between wireless cells (called roaming) without losing contact with the network
(Figure 11). This is possible because the wireless network adapters in the client computers automatically switch to
the best available device. Authentication and billing (if used) are maintained. Figure 11 shows roaming across
several LPS-20xs.
Figure 11. Roaming
MAC-LEVEL FILTERING
When enabled, this option enables you to control access to the wireless network based on the MAC address of
client stations. You can either block access or allow access depending on your requirements.
LOCATION-AWARE AUTHENTICATION
This feature enables you to control logins to the public access network based on the wireless access point a
customer is connected to. This feature works when you use the LPS-20x in conjunction with an LPS-21x or a
Colubris access controller (e.g., CN3000) that also supports the Location-Aware Authentication. If you enable this
option, when a customer attempts to login to the public access network, the access controller sets the Called-
Station-ID in the RADIUS access request to the MAC address of the wireless port the customer is associated with.
Server-side code can be written to manage access based on this information.

MULTIPLE SSID AND VLAN SUPPORT
The LPS-20x provides support for multiple Service Set Identifiers (SSIDs) (Figure 13). This allows the wireless
network to be segmented into multiple distinct entities, each with its own SSID. This feature is very useful when
combined with Virtual Local Area Network (VLAN) support. For example, in this scenario public and private users
share the same infrastructure with complete security.
Figure 13. Multiple SSID amd VLAN Support
The wireless network is split into two WLANs: public and private:
• The Public WLAN maps authentication traffic between the LPS-20x and the Access Controller on VLAN
60. Once a user is authenticated, traffic to the Internet does not use a VLAN.
• The Private WLAN maps authentication traffic between the LPS-20x and the RADIUS Server on VLAN
70. Once a user is authenticated, traffic to the Internet or Corporate Intranet is mapped across VLANs 51,
52, 53.

PLANNING YOUR INSTALLATION
OVERVIEW
The LPS-20x enables you to extend the coverage of a public access network. One or more LPS-20xs can be
installed in conjunction with an access controller (Figure 14).
Figure 14. Access Controller
ACCESS CONTROLLER
The access controller provides user authentication and accounting support for the wireless customers and manages
the security of the network. This means ensuring that only authorized traffic is permitted to reach the protected
network resources. If connected to the Internet, its integrated firewall provides protection from hackers.

LPS-20X
The LPS-20x (and the access controller) provide wireless network coverage in a radius of up to 100 meters
(300 feet). This is called a wireless cell. To maximize coverage of the cell, the LPS-20x is best installed in an open
area with as few obstructions as possible. Try to choose a location that is central to the area being served.
The LPS-20x uses radio waves in the 2.4 Ghz band to communicate with client stations. Radio waves cannot
penetrate metal, instead they are reflected. This means that the LPS-20x is able to transmit through wood or plaster
walls, and closed windows. However, the steel reinforcing found in concrete walls and floors may block
transmissions or reduce signal quality by creating reflections. This can make it difficult for a single LPS-20x to serve
users on different floors in a concrete building. Such installations will require a separate LPS-20x on each floor.
Client computers are able to move between cells (called roaming) without loosing contact with the network. This is
possible because wireless adapters automatically switch to the best available LPS-20x.
INSTALLATION STEPS
1. Install the LPS-20x (Installation and Test on page 19).
2. Establish a connection to the management tool (Management Tool on page 35).
3. Define management tool security settings (Management Tool Security on page 46).
4. Configure and deploy the wireless network (Configuration – Setting up the Wireless LAN on page 62).
5. Configure the connection to the access controller
(Configuring the Connection to the Access Controller on page 79).
6. Configure the service sensor (optional) (Service Sensor on page 94).
7. Configure MAC-level filtering (optional) (MAC-Level Filtering on page 96).
8. Configure location-aware authentication (optional) (Location-Aware Authentication on page 97).

MANAGEMENT TOOL
The management tool is a Web-based interface to the LPS-20x that provides easy access to all configuration
functions via WLAN, LAN, or Internet Port.
MANAGEMENT STATION
The management station is the computer that you will use to connect to the management tool. To act as a
management station, a computer must:
• have a JavaScript-enabled Web browser installed (Netscape 7.1 or higher, or Internet Explorer 6.0 or
higher)
• be able to establish an IP connection with the LPS-20x
Although there are several ways to manage the LPS-20x after installation (see Management scenarios below), the
first time you configure the LPS-20x you should do so from a computer equipped with a wireless LAN card. If it is
impossible to install a wireless LAN card in your computer, you can use a computer equipped with an Ethernet card
instead. This requires a cross-over Ethernet cable.
CONFIGURING THE MANAGEMENT STATION FOR WIRELESS ACCESS
Install and configure the wireless adapter in the management station according to the directions that came with it.
During installation make sure that:
• encryption is disabled
• TCP/IP is installed and configured. The IP address of the wireless station must be on the same subnet as
the access point.
• Set the SSID to be “ADC”.
CONFIGURING THE MANAGEMENT STATION FOR WIRED ACCESS
Install and configure a network adapter in the management station according to the directions that came with it.
During installation make sure that TCP/IP is installed and configured.
!
IMPORTANT Only one administrator can be logged into the management tool at a given time. If a second
administrator logs in while the first is connected, the first administrator may be logged out
depending on system configuration (refer to Management|Management Tool|Login override).
A static IP address must be used when configuring the LPS-20x for the first time. Refer to Connecting to
the LPS-20x for the First Time on page 37.

MANAGEMENT TOOL SECURITY
The management tool is protected by the following security features.
ADMINISTRATOR PASSWORD
Access to the LPS-20x management tool is protected by a username and password to safeguard configuration
settings. The factory default setting for username is admin and password is admin. It is strongly recommended that
you change both.
To change the username and/or password, do the following:
1. On the main menu, click Management. The Management tool configuration page opens.
2. In the Administrator authentication box, enter the new username, current password, the new password,
and then repeat the new password for confirmation.
3. Click Save when you are done.
WARNING Failure to change the user name and password will leave your network at an increased risk of
attack.
WARNING If you forget the administrator password, the only way to gain access to the management tool is

December 20, 2004 SCP-LPS20x-011-012-01H
ADC Telecommunications, Inc. 47
ADMINISTRATOR AUTHENTICATION PARAMETERS
Authentication Via
Choose how the administrator’s username and password are verified. You can choose to store this information on
the LPS-20x (local account) or remotely on a RADIUS Server. Using a RADIUS Server enables you to have multiple
administrators, each with a unique name and password. To use a RADIUS Server, you must define a RADIUS
profile in Security>RADIUS.
Username
Login name for the administrator. The default login is “admin”.
Current Password
Current administrator password. New passwords must be at least six characters long and contain at least four
different characters. The default password is “password#1”.
New Password
Specify the new administrator password.
Confirm New Password
Retype the new administrator password.
LOGIN OVERRIDE
Allow administrator override login
When this option is enabled, an active administrator’s session will be terminated by the login of another
administrator. This prevents the management tool from being locked by an idle session until the timeout expires.
WEB SERVER PARAMETERS
Secure Web Server Port
Specify the port number the LPS-20x will use to provide secure access to the managment tool (HTTPS). By default,
this parameter is set to port 443.
Web Server Port
Specify the port number the LPS-20x will use to provide standard HTTP access to the management tool. HTTP
connections made to this port are met with a warning and the browser is redirected to the secure web server port. By
default, this parameter is set to port 80.
SCP-LPS20x-011-012-01H December 20, 2004
48 ADC Telecommunications, Inc.
VALIDATING ADMINISTRATOR LOGINS USING A RADIUS SERVER
You can use a RADIUS server to authenticate logins to the management tool. One advantage of this is that it
enables you to create several administrator accounts, each with its own username and password.
To setup RADIUS authentication, do the following:
1. On the main menu, click Security then click RADIUS. The Radius profiles page opens.
2. Click Add New Profile. The Add Radius profiles page opens.
3. Define the settings for the RADIUS profile you want to use to validate administrator logins. Either use an
existing profile or add a new one.
4. Click Save.
5. On the main menu, click Management. The Management tool configuration page opens.
6. In the Administrator authentication box, select the RADIUS server you defined in Step 2.
7. Click Save.
!
IMPORTANT Make sure that the RADIUS profile you select is configured and that the administrator account is
defined on a functioning RADIUS server. If not, you will not be able to log back into the LPS-20x
because the administrator password cannot be authenticated.
December 20, 2004 SCP-LPS20x-011-012-01H
ADC Telecommunications, Inc. 49
CONNECTION SECURITY
To maintain the integrity of the configuration settings, only one user can be connected to the management tool at a
given time. To prevent the management tool from being locked up by an idle user, two mechanisms are in place:
• If a user’s connection to the management tool remains idle for more than ten minutes, the LPS-20x auto-
matically logs the user out.
• If a second user connects to the management tool and logs in with the correct username and password,
the first user’s session may be terminated depending on system configuration. Refer to Manage-
ment|Management Tool|Login override.
HTTPS
Communications between the management station and the LPS-20x occurs via HTTPS. Before logging into the
management tool, users must accept an ADC certificate. You can replace this certificate with your own. For more
information, refer to SSL Certificates on page 139.
SECURITY SETTINGS
The LPS-20x can be managed both locally and remotely for complete flexibility. Management occurs via the Web-
based management tool which resides on the LPS-20x. For details, refer to Management Scenarios on page 36.
To Configure Security Options
1. On the main menu, click Management. The Management tool configuration page opens.
2. In the Security box, enable the management options you require. The options are described in the section
that follows.
3. Click Save.
!
IMPORTANT If you do not log out, the LPS-20x continues to maintain your connection as active until it times
out (after 10 minutes of inactivity). During this period, no other user can connect to the
management tool unless Login override under Management|Management Tool is checked.

CONFIGURING REMOTE MANAGEMENT SUPPORT
If the LPS-20x is installed behind an access controller or RADIUS server, enabling remote access to the
management tool requires configuration settings to be defined on the access controller, RADIUS server, and the
LPS-20x. This section explains how to accomplish this for the following two scenarios (Figure 16):
Figure 16. Configuring Remote Management Support
To reach the management tool, the management stations specify the following addresses in their web browsers:
SCENARIO 1
• To reach LPS-20x A: HTTPS://192.168.10.1:5002
• To reach LPS-20x B: HTTPS://192.168.10.1:5003
SCENARIO 2
• To reach LPS-20x A: HTTPS://192.168.30.2:5002
• To reach LPS-20x B: HTTPS://192.168.30.2:5003
Static NAT mappings are used on the access controller to direct traffic to the proper LPS-20x. MAC address
authentication enables the LPS-20xs to log into the public access network. Access list definitions allow traffic to be
sent from the LPS-20xs to the management stations.
The following sections explain these configuration settings in more detail.

ON THE ACCESS CONTROLLER
Create static NAT mappings
To direct management traffic to the proper LPS-20x, you need to create static NAT mappings to redirect HTTPS
traffic to the new ports you defined on the LPS-20xs.
• Map traffic on port 5002 to IP address 192.168.1.2 and port 443.
• Map traffic on port 5003 to IP address 192.168.1.3 and port 443.
ON THE RADIUS SERVER
CONFIGURE THE ACCESS CONTROLLER PROFILE
MAC address authentication
For the LPS-20x to communicate with the remote management station, it must log into the public access network.
To accomplish this, use the MAC address attribute when creating the RADIUS profile for the access controller. This
attribute enables the access controller to authenticate devices based on their MAC address. For details, see the
access controller’s administrator’s guide.
Access list
In both scenario 1 and 2, it makes sense to protect access to the RADIUS server and management station. This is
done with an access list definition that blocks all traffic to 192.168.20.0 for scenario 1, and 192.168.30.0 for scenario
2.
However, to enable the LPS-20xs and the management station to communicate, you must create an additional
access list definition as follows:
• Scenario 1: Create an access list that permits HTTPS traffic to address 192.168.20.4.
This is the IP address of the management station. For example:
access-list=LPS-20x,ACCEPT,tcp,192.168.20.4,443
• Scenario 2: The list should permit HTTPS traffic to address 192.168.30.3.
This is the IP address of the management station inside the VPN tunnel.
access-list=LPS-20x,ACCEPT,tcp,192.168.30.3,443
CREATE A LPS-20X PROFILE
Define a RADIUS profile for the LPS-20xs. The profile should activate the access list that was defined in the access
controller profile. For example:
use-access-list=LPS-20x
CREATE A USER ACCOUNT FOR EACH LPS-20X
Define a RADIUS user account for each LPS-20x. Define a unique username and password for each device.

FIRMWARE MANAGEMENT
Firmware updates can be handled manually, automatically, or with a tool like cURL.
MANUAL UPDATE
1. On the Maintenance menu, click Firmware updates.
2. In the Install firmware box, click the Browse button and select the .cim file you just unzipped.
3. Click Install.
!
IMPORTANT When an LPS-20x is restarted, it automatically initializes itself to the default address 192.168.1.1.
If the DHCP client is enabled on the Internet port, it takes about 30 seconds after the restart for
the DHCP client to request an address. Therefore, for a short period of time after restarting, the
LPS-20x may conflict with another device on the network. This will usually not be an issue.
However, if you are using an automated tool (like cURL) to update the configuration/firmware on
several LPS-20xs at the same time, you may experience difficulties. It is recommended that you
schedule your updates to occur in succession, leaving a three minute interval between each
device.
This procedure assumes you have already loaded and unzipped the .cim file to your local hard drive.
The LPS-20x will automatically restart after the firmware has been installed. This will disconnect all client
stations. Once the LPS-20x resumes operation, all client stations will have to reconnect. Configuration
settings are preserved during firmware upgrades.
SCP-LPS20x-011-012-01H December 20, 2004
54 ADC Telecommunications, Inc.
FIRMWARE UPDATE PARAMETERS
Firmware Updates
The firmware is special software that controls the operation of the LPS-20x. Periodically, ADC will make new
versions of the firmware available.
Install Firmware
Two options are available: Manual and Scheduled.
Manual
Click the Browse button and then locate a firmware file. Select it, and then click Install to upload it to the LPS-20x.
When installation is complete, the LPS-20x will automatically restart.
Scheduled
The LPS-20x can automatically retrieve and install firmware from a local or remote URL at preset times. By placing
LPS-20x firmware on a web or ftp server, you can automate the update process for multiple units.
Click the validate button to check if the URL you specified points to a valid firmware file.
When the update process is triggered, the LPS-20x retrieves the first 2K of the firmware file to determine if it is
different than the active version. If different (older or newer version), the entire firmware file is then downloaded and
installed. This enables you to return to other firmware version, if required.
Configuration settings are preserved during the update unless stated otherwise in the release notes for the firmware.
However, all active connections will be terminated. Customers will have to log in again after the LPS-20x restarts.
All configuration settings are preserved during the update unless stated otherwise in the release notes for
the firmware.
December 20, 2004 SCP-LPS20x-011-012-01H
ADC Telecommunications, Inc. 55
Using cURL
It is possible to automate management tasks using a tool like cURL. cURL is a software client that can be used to
get/send files to/from a server using a number of different protocols (HTTP, HTTPS, FTP, GOPHER, DICT,
TELNET, LDAP or FILE).
cURL is designed to work without user interaction or any kind of interactivity. It is available for Windows and LINUX
at: http://curl.haxx.se/. You must use version 7.9.8 or higher.
The following cURL commands illustrate how to update the firmware. The following setup is assumed:
• IP address of the LPS-20x’s Internet port is 24.28.15.22.
• Management access to the Upstream port is enabled.
• Firmware is located in LPS2xx.CIM.
Login to the management interface.
curl --dump-header cookie.txt -s -m 60 "https://24.28.15.22/goform/
Logout?username=admin&pw=admin"
Prepare the LPS-20x to receive the firmware update.
curl --cookie cookie.txt -m 60 "https://24.28.15.22/script/firmware_init.asp"
Upload the firmware. Once the upload is complete, the LPS-20x will automatically restart.
curl --cookie cookie.txt -s -m 600 -F firmware=@LPS20x.cim -F backup=Install

IMPORTANT When an LPS-20x is restarted, it automatically initializes itself to the current address (default is
192.168.1.1). If the DHCP client is enabled on the Internet port, it takes about 30 seconds after the
restart for the DHCP client to request an address. Therefore, for a short period of time after
restarting, the LPS-20x may conflict with another device on the network. This will usually not be
an issue. However, if you are using an automated tool (like cURL) to update the configuration/
firmware on several LPS-20xs at the same time, you may experience difficulties. It is
recommended that you schedule your updates to occur in succession, leaving a three minute
interval between each device.
WARNING Resetting to factory defaults sets the administrator password to ‘admin’ and resets all configuration
settings.

December 20, 2004 SCP-LPS20x-011-012-01H
ADC Telecommunications, Inc. 63
Broadcast WLAN name (SSID)
When this option is enabled, the LPS-20x will broadcast its wireless network name (SSID) to all client stations. Most
wireless adapter cards have a setting that enables them to automatically discover access points that broadcast their
names and automatically connect to the one with the strongest signal. If you disable this option, client stations will
have to specify the network name you enter for WLAN name when they connect.
Permit traffic exchange between wireless client stations
Enable this option to allow wireless client stations to exchange data with one another. By default, the LPS-20x
blocks all traffic between wireless client stations.
RADIO PARAMETERS
Wireless Mode
The transmission speed and frequency band is 802.11b: 11 Mbps in the 2.4 GHz frequency band.
Operating Frequency
Select the correct frequency for the LPS-20x to operate in. The frequencies that are available are determined by the
radio installed in the LPS-20x and the regulations that apply in your country.
For optimum performance when operating in 802.11b mode, choose a frequency that differs from other wireless
access points operating in neighboring cells by at least 25 MHz. Consult the Wireless > Neighborhood page to
view a list of access points currently operating in your area.
Distance Between Access Points
Use this parameter to adjust the receiver sensitivity of the LPS-20x. This parameter should only be changed if:
• you have more than one wireless access point installed in your location
• you are experiencing throughput problems
In all other cases, use the default setting of Large. If you have installed multiple LPS-20xs, reducing the receiver
sensitivity of the LPS-20x from its maximum level will help to reduce the amount of crosstalk between the wireless
stations to better support roaming clients. By reducing the receiver sensitivity, client stations will be more likely to
connect with the nearest access point.
RTS Threshold
Use this parameter to control collisions on the link that can reduce throughput. If the Status -> Wireless page
shows increasing values for Tx multiple retry frames or Tx single retry frames, you should adjust this value until
the errors clear up. Start with the largest value and slowly decrease until errors are minimized. Note that using a
small value for RTS threshold can affect throughput.
If a packet is larger than the threshold, the LPS-20x will hold it and issue a request to send (RTS) message to the
client station. Only when the client station replies with a clear to send (CTS) message will the LPS-20x send the
packet. Packets smaller than the threshold are transmitted without this handshake.
Transmit Power
Use this parameter to set the transmission power of the wireless radio.
• HIGH: Sets the maximum transmission power the wireless card is capable of. It will be either 100 mW (20
dBm) or 200 mW for North America (23 dBm).
• MEDIUM: 17 dBm
• LOW: 13 dBm

connected to the Internet port.
WIRELESS PROTECTION PARAMETERS
Select the type of protection you want to use for the wireless network.
WPA
This option enables support for users with Wi-Fi Protected Areas (WPA) client software.
Key Source
This option determines how the Temporary Key Integrity Protocol (TKIP) keys are generated.
• RADIUS: The LPS-20x obtains the Microsoft Point-to-Point Encryption (MPPE) protocol key from the
RADIUS server. This is a dynamic key that changes each time the user logs in and is authenticated. The
MPPE key is used to generate the TKIP keys that encrypt the wireless data stream. Select the appropriate
RADIUS server.
• Preshared Key: The LPS-20x uses the key you specify in the Key field to generate the TKIP keys that
encrypt the wireless data stream. Since this is a static key, it is not as secure as the RADIUS option.
Specify a key that is between 8 and 64 characters in length. It is recommended that the preshared key be
at least 20 characters long, and be a mix of letters and numbers.
Key/Confirm key
Specify a key that is between 8 and 64 characters in length.

interval are set in the Dynamic keys box.
WEP
Key 1, 2, 3, 4
The number of characters you specify for a key determines the level of encryption the LPS-20x will provide.
• For 40-bit encryption, specify 5 ASCII characters or 10 HEX digits
• For 128-bit encryption, specify 13 ASCII characters or 26 HEX digits
When encryption is enabled, wireless stations that do not support encryption cannot communicate with the LPS-20x.
The definition for each encryption key must be the same on the LPS-20x and all client stations. Keys must also be in
the same position. For example, if you are using key 3 to encrypt transmissions, then each client station must also
define key 3 to communicate with the LPS-20x.
Transmission key
Select the key the LPS-20x will use to encrypt transmitted data. All four keys are used to decrypt received data.
Key format
Select the format you used to specify the encryption keys:
ASCII
ASCII keys are much weaker than carefully chosen HEX keys. You can include ASCII characters between 32 and
126, inclusive in the key. However, note that not all client stations support non-alphanumeric characters such as
spaces, punctuation, or special symbols in the key.

WIRELESS PROTECTION PARAMETERS
Select the type of protection you want to use for the wireless network.
WPA
This option enables support for users with WPA client software.
Key Source
This option determines how the TKIP keys are generated.
• RADIUS: The LPS-20x obtains the MPPE key from the RADIUS server. This is a dynamic key that
changes each time the user logs in and is authenticated. The MPPE key is used to generate the TKIP
keys that encrypt the wireless data stream. Select the appropriate RADIUS server.
WPA sessions are terminated by the LPS-20x. This means that the LPS-20x handles all authentication
tasks and must communicate with the RADIUS server or access controller to validate login credentials.
The LPS-20x sends this authentication traffic on the downstream port. Therefore, the RADIUS server or
access controller must be reachable via this port.
• Preshared Key: The LPS-20x uses the key you specify in the Key field to generate the TKIP keys that
encrypt the wireless data stream. Since this is a static key, it is not as secure as the RADIUS option.
Specify a key that is between 8 and 64 characters in length. It is recommended that the preshared key be
at least 20 characters long, and be a mix of letters and numbers.
RADIUS Profile

DNS MANAGEMENT
OVERRIDING DYNAMICALLY ASSIGNED DNS SERVERS
If required, you can override the DNS servers dynamically assigned by PPPoE or DHCP as follows:
1. In the management tool, click Network, then click DNS. The DNS configuration page opens.
2. Specify the addresses of Server 1 and Server 2.
3. Click Save when you are done.
DNS SERVER PARAMETERS
Server 1
Specify the IP address of the first DNS server that the LPS-20x will use.
Server 2
Specify the IP address of the second DNS server that the LPS-20x will use.
DNS cache
Enables the DNS cache. Once the host name has been successfully resolved to an IP address by a remote DNS
server, it is stored in the cache. This speeds up network performance as the remote DNS server now does not have
to be queried for subsequent requests for this host.
The entry stays in the cache until:
• an error occurs when connecting to the remote host
• the time to live (TTL) of the DNS request expires
• the LPS-20x is restarted
SETTING UP A MULTI-CELL WIRELESS NETWORK
Multiple LPS-20xs are installed in conjunction with a RADIUS Server to provide multiple wireless cells for coverage
of large locations. Client computers are able to move between cells (called roaming) without losing contact with the
network. This is possible because wireless adapters automatically switch to the best available wireless access point.
December 20, 2004 SCP-LPS20x-011-012-01H
ADC Telecommunications, Inc. 71
OPERATING FREQUENCY
When using multiple units, it is important that each pair of wireless cells that overlap be set to operate on a different
channel. This helps to eliminate crosstalk and increase performance. For information on selecting operating
frequencies, refer to Configuring Overlapping Wireless Cells on page 72.
NETWORK BANDWIDTH CONTROL
These parameters enable you to limit the flow of data traffic through the LPS-20x by controlling the outgoing
bandwidth allocated to each port.
1. On the Network menu, click Bandwidth control.
OUTGOING TRAFFIC THROTTLE PARAMETERS
These parameters enable you to limit the data traffic through the LPS-20x by controlling the outgoing bandwidth
allocated to each port. Note that the LPS-212 is shown, but the LPS-20x screen is identical to the LPS-212.
• If outgoing traffic arrives at the port at the defined bandwidth limit (or less), it is processed without delay.
• If outgoing traffic arrives at the port at a rate that is greater than the defined bandwidth limit, it causes the
LPS-20x to throttle the traffic for that port.
• If the traffic rate is over-limit for just a short burst, the data will be queued and forwarded without loss. If
the traffic rate is over-limit for sustained period, the LPS-20x will drop data to bring the rate down to the
bandwidth limit that is set.
Examples:
• If you want to limit the traffic that wireless client stations can download from the Internet to 500 kbps, set a
value of 500 for the wireless port.
• If you want to limit the traffic that LAN client stations can download from the Internet to 1000 kbps, set a
value of 1000 for the LAN port.
• If you want to limit the traffic that wireless and LAN client stations can upload to the Internet to 800 kbps,
set a value of 800 for the Internets port.
These are aggregate values per port and not per user values.

CONFIGURING OVERLAPPING WIRELESS CELLS
Overlapping wireless cells are caused when two or more access points are within transmission range of each other.
This may be under your control (when setting up multiple cells to cover a large location) or out of your control (when
your neighbors set up their own wireless networks.). In either case, the problems you face are similar.
PERFORMANCE DEGRADATION AND CHANNEL SEPARATION
When two wireless cells operating on the same frequency overlap, it can cause a reduction in throughput in both
cells. This occurs because a wireless station that is attempting to transmit will defer (delay) its transmission if
another station is currently transmitting. On a network with many clients and a lot of traffic, this can severely affect
performance as stations defer multiple times before the channel becomes available. If a station is forced to delay its
transmission too many times, data may be lost.
Delays and lost transmissions can severely reduce throughput on a network. Use the Wireless option on the Status
menu to view this information on your network.
Figure 17 shows two overlapping wireless cells operating on the same frequency. Since both access points are
within range of each other, the number of deferred transmissions will be large.

The solution to this problem is to set the two networks to different channels with as great a separation as possible in
their operating frequencies. This reduces cross-talk and enables client stations connected to each access point to
transmit at the same time.
CHOOSING CHANNELS
For optimum performance when operating in 802.11b mode, choose a frequency that differs from other wireless
access points operating in neighboring cells by at least 25 MHz. (Note that this is the recommended minimum. Two
channels with this separation will always perform worse than two channels using the maximum separation. So it is
always best to use the greatest separation possible between overlapping networks.)
Consult the Wireless > Neighborhood page to view a list of access points currently operating in your area.
With the proliferation of wireless networks, it is very possible that the wireless cells of access points outside your
control may overlap your intended area of coverage. To generate a list of all access points operating near you and
view their operating frequencies, go to Wireless > Neighborhood.
The set of available channels is automatically determined by the LPS-20x, based on the Country setting that has
been programmed into the firmware. Available channels can be viewed on the Wi-Fi page. This means that the
number of non-overlapping channels available to you will vary. This will affect how you set up your multi-cell
network.
Channel Availability
The LPS-20x supports the following 14 channels in the 2.4 GHz band (Table 11).
