CHAPTER 1 Intr oduction to Raven
CDMA/1xRTT
The AirLink Raven’s serial port can be connected to a computer or other device.
The Raven uses CDMA/1xRTT to connect to TELUS’s cellular network to allow
communication to the Internet.
Raven Overview
The Raven's rugged form factor is ideal for industrial and commercial applications
that require real-time communications. The Raven provides cellular data communications for a variety of applications, such as telemetry, public safety, SCADA, traffic control, traffic metering, transit arrival systems and more.
FIGURE 1. Raven front and back
TELUS CDMA/1xRTT Raven User Guide Version 2.09 1
Introduction to Raven CDMA/1xRTT
The Raven has several built in features to make it more effective in a variety of settings. In addition, Airlink provides several modem tools to further enhance the
capabilities of the
Guide.
Raven. These features and tools are introduced in this User
• Wireless ACE, Wireless ACE Web, and AceNet
• IPManager
• Modem Doctor
• Keepalive
CDMA/1xRTT Overview
Code Division Multiple Access (CDMA) provides a digital cellular telephony system provides wireless Internet access at speeds between 60 and 80 kbps, with bursts
up to 144 kbps.
Establishing a Internet Connection
The Internet Service Provider (ISP) from you to the Internet is TELUS with your
Raven as the connection to TELUS.
When your Raven is powered on, it automatically searches for cellular service
using CDMA/1xRTT and establishes a PPP (Point to Point Protocol or “dial” up
connection) link to TELUS’s network. As soon as the Raven receives its IP, it’s
ready to create a network between your computer or device and TELUS’s network
so you can use TELUS to communicate on the Internet.
To use your Raven to connect to the Internet from your computer, you need to connect the computer directly to the Raven’s serial port and use Dial-Up Networking
(DUN).
TELUS CDMA/1xRTT Raven User Guide Version 2.09 2
Introduction to Raven CDMA/1xRTT
FIGURE 2. Using the Raven to connect to the Internet
Note: Private network connections are unique for each configuration and
not covered as part of the standard installation.
Using CDMA/1xRTT to Communicate with Your Equipment
There are two types of addresses in TCP/IP, dynamic and static.
• Dynamic addresses are assigned on a “need to have” basis. Your Raven might
not always receive the same address each time it connects with TELUS.
• Static addresses are permanently assigned to a particular account and will
always be used whenever your
will not be given to anyone else.
If you need to contact the Raven, a device connected to the modem, or a host system using the modem, you need to have a known IP (such as one which is static) or
domain name (an IP address which is converted by a DNS server into a word based
name).
Most ISPs (cellular included) use dynamic IP addresses rather than static IP
addresses. A dynamic IP address is suitable for many common Internet uses, such
as web browsing, looking up data on another computer system, or other client func
tion (such as data only being sent out or only being received after an initial request).
Raven connects to the Internet. The IP address

Introduction to Raven CDMA/1xRTT
If you have a dynamic IP address for your Raven, you can use a service (such as IP
Manager, covered later in this User Guide) to translate a dynamic IP address to a
fully qualified domain name so you can contact the
Caution: The IP address given to your Raven by TELUS must also be
Internet routable if the computer you need to connect to the Raven is not
connected directly to TELUS's IP network. Please check with TELUS to
confirm you IP is scheme is correct for your application and needs.
Raven as if it had a static IP.
Common Uses for the Raven
The Raven’s rugged construction and cellular connection make it ideal for use in
remote and/or industrial locations. The Raven can be used for telemetry and for
more advanced communication to the device or devices behind it.

CHAPTER 2 Raven Activation
Your Raven needs specific parameters before it can operate on the CDMA/1xRTT
network. Generally TELUS will provide you with the necessary parameters to get
the Raven configured.
Connecting the Raven to your computer
Your Raven’s serial port can be connected directly to most computers or devices
using a standard straight through serial cable.
Quick Start Guide and Setup Wizard
The preferred way to configure and activate your Raven is via the AirLink Setup
Wizard for TELUS and CDMA/1xRTT. The Quick Start Guide will lead you
through the using the Setup Wizard.
• The Raven Setup Wizard for CDMA/1xRTT and TELUS is available from the
AirLink web site, http://www.airlink.com/support.
• The Quick Start Guide is also available at the AirLink web site.
TELUS CDMA/1xRTT Raven User Guide Version 2.09 6
Raven Activation
Note: The web site may have a more recent Setup Wizard and Quick
Start Guide than those included with your Raven. It is recommended that
you check with the web site for the latest version before installing your
Raven. You will need to look for TELUS, CDMA/1xRTT, and the
Raven. Other Setup Wizards may not work to connect you to TELUS.
To run the Setup Wizard, you will need the Microsoft .NET framework
and Microsoft Windows 98, Microsoft Windows 2000, Microsoft Windows XP, or
later.

Raven Activation
Configuring the Raven using Wireless ACE
You can configure your modem using Wireless ACE (page 11) or AceNet
(page 13). It is not recommended to activate a modem using either Wireless ACE
or AceNet. An alternate method to configure and activate your Raven is by AT
commands (full listing beginning on page 58) sent directly to the modem via a terminal application (page 55). This method is recommended only in situations where
the Setup Wizard is not available and/or the configuration for the Raven is unusual.
Raven Indicator Lights
When your Raven is connected to power and an antenna, there is a specific pattern
to the lights to indicate its operation mode.
FIGURE 2. Raven indicator lights
Tx (transmit) and Rx (receive) - Lights will flash as data is transferred to and
from the
RSSI - Light shows the strength of the signal and may be nearly solid (strong
signal) or flashing (weaker signal). A slow flash indicates a very weak si gnal.
Reg - Indicates the Raven has acquired an IP from TELUS.
Chan - Indicates the modem has acquired a network channel.
Link - Indicate a successful connection to the cellular network.
Pwr - Indicates the power adapter is connected and there is power getting to the
modem.
The Reset button performs the same function as unplugging power from the
modem and plugging it back in. Reset will not alter any saved configuration
settings.

CHAPTER 4 DNS: Using Names
Instead of IP addr esses
A domain name is a name of a server or device on the Internet which is associated,
generally, with an IP address. In a way, a domain name is like the street address of
your house with the phone number being like the IP address. You can contact the
house either by going to the address (name) or by calling the phone number (IP
address).
Domain Name Service (DNS) is a network service which translates, or redirects,
the IP address, allowing someone to contact that address via the name. A DNS
server is registered to handle all addresses of a particular domain (much like the
post office for a particular town or city is known to the post offices of all other
towns and cities and is authorized to give the addresses of locations in its own loca
tion).
-
Configuring DNS
The Raven has an internal DNS resolver with which it can query DNS servers in
order to translate names into IP addresss which it can then use internally. Generally, when your Raven receives its IP address from TELUS, it will also be configured to use TELUS’s DNS servers to use for resolving (or translating) names to IP
addresses. In that case, the only one which is not overwritten is the alternate DNS.
TELUS CDMA/1xRTT Raven User Guide Version 2.09 14
DNS: Using Names Instead of IP addresses
You can use AT commands (page 58), Wireless ACE (page 11), and ACE Net
(page 12) using a template built from Wireless ACE to configure DNS in your
Raven.
FIGURE 1. Wireless ACE: DNS
*DNS1 and *DNS2 - Set these to your primary and secondary DNS servers.
These maybe be overwritten by
TELUS when your Raven gets its IP address.
*DNSUSER - Set this, if desired, to an additional DNS server to query first
before the primary or secondary (just as a hosts file is queried first on a com
puter). If *DNSUSER is set to 0.0.0.0, it will be ignored.
*DNSUPDATE - This command sets how often you want DNS Updates to be
forced. Otherwise the
Raven will only send updates when it is reset, powered
up, or the IP address granted by the network changes.
-
Note: If you will be using your Raven to communicate with another AirLink modem and both are using IP Manager (page 16) to translate
dynamic IP addresss to domain names, it is recommended that you set
*DNSUSER to the IP address for IP Manager. IP Manager’s updates
occur more frequently than
TELUS’s DNS servers decreasing the time
between IP address change and address resolution.
PPP-Peer
The Raven uses the unqualified domain name of “ppp-peer” when it is PPP or SLIP
address mode to resolve the address of the device or computer connected via PPP or
SLIP address. If the
Raven is not in PPP or SLIP address mode, “ppp-peer” will
resolve to 0.0.0.0.
15 TELUS CDMA/1xRTT Raven User Guide Version 2.09
CHAPTER 5 IP Manager
IP Manager translates a dynamic IP address to a fully qualified domain name so
you can contact
Since TELUS frequently does not offer static IP addresses, IP Manager is a free service provided by AirLink for your Raven to translate a dynamic IP address into a
fully qualified domain name so it can be contacted directly on the Internet.
Raven by name as if it had a static IP.
• Dynamic IP addresses are granted only when a modem or other device is con-
nected and can change each time the modem or device reconnects to the network.
• Static IP addresses are granted the same address every time the modem or
device is connected.
A dynamic IP address is suitable for many Internet activities such as web browsing,
looking up data on another computer system, data only being sent out, or data only
being received after an initial request. However, if you need to contact the
directly, a device connected to the modem, or a host system using the Raven, a
dynamic IP won’t give you a reliable address to contact (since it may have changed
since the last time it was assigned).
TELUS CDMA/1xRTT Raven User Guide Version 2.09 16
Raven
IP Manager
Fully Qualified Domain Name
A fully qualified domain name (FQDN) generally has several parts.
• Top Level Domain (TDL): The TDL is the ending suffix for a domain name
(.com, .net, .org, etc.)
• Country Code Top Level Domain (ccTDL): This suffix is often used after the
TDL for most countries except the US (.ca, .uk, .au, etc.)
• Domain name: This is the name registered with ICANN (Internet Corporation
for Assigned Names and Numbers) or the registry for a the country of the
ccTDL (i.e. if a domain is part of the .ca TDL, it would be registered with the
Canadian domain registry). It is necessary to have a name registered before it
can be used.
• Sub-domain or server name: A domain name can have many sub-domain or
server names associated with it. Sub-domains need to be registered with the
domain, but do not need to be registered with ICANN or any other registry . It is
the responsibility of a domain to keep track of its own subs.
A URL (Universal Resource Locator) is different from a domain name in that it
also indicates information on the protocol used by a web browser to contact that
address, such as http://www.airlink.com.
• .com is the TDL
• airlink is the domain (usually noted as airlink.com since the domain is specific
to the TDL)
• www is the server registered with AirLink.com
• http:// is the protocol (html or web) used to access the webpage for AirLink
Dynamic Name Resolution
When an IP address is not expected to change, the DNS server can indicate to all
queries that the address can be cached and not looked up for a long period of time.
Dynamic DNS servers, conversely, have a short caching period for the domain
information to prevent other Internet sites or queries from using the old informa
tion.
17 TELUS CDMA/1xRTT Raven User Guide Version 2.09
-
IP Manager
If the Raven is configured for Dynamic IP, when the Raven first connects to the
Internet, it sends a IP change notification to IP Manager. IP Manger will acknowledge the change and update the DNS record. The changed IP address will then be
the address for the
Raven’s configured name.
Once the Raven’s IP has been updated in IP Manager , it can be contacted via name.
If the IP address is needed, you can use the domain name to determine the IP
address.
The fully qualified domain name of the Raven will be a subdomain of eairlink.com.
Note: Earlink.com is a domain name owned and registered by AirLink
for IP Manager.
Configuring the Raven for Dynamic IP
T o configure the Dynamic IP settings in your Raven so that it will use IP Manager,
you can use AT commands (page 58), using direct serial communication or Telnet
(page 55), Wireless ACE (page 11), and ACE Net (page 12) using a template built
from Wireless ACE.
To configure your AirLink modem to be addressed by name, the mo dem needs to
have 4 elements configured.
FIGURE 1. Wireless ACE: Dynamic IP (IP Manager configuration)
1. Modem name: The name you want for the modem.
2. Domain: Eairlink.com is the IP Manager domain provided by AirLink.
TELUS CDMA/1xRTT Raven User Guide Version 2.09 18
IP Manager
3. IP Manager IP Address: The IP or domain name of the dynamic DNS server.
Earlink.com is the IP Manger server provided by AirLink. Note: To use the
name here instead of the IP, you need to have DNS set up in your
“DNS: Using Names Instead of IP addresses” on page 14.
4. IP Manager update interval: How often you want the address sent to IP Man-
ager. If this is set to zero, the modem will only send an update if the IP changes
(i.e. if the modem is reset or is assigned a different IP).
In Wireless ACE, select Dynamic IP to configure your modem to use IP Manager.
You can configure a second dynamic server as a backup, secondary, or alternate
server.
Note: For the Modem Name, you should use something which is unique
but also easy to remember. Your company name or the intended function
of the modem are recommended. If you have more than one modem,
append a number for each.

CHAPTER 6 Keepalive
It is not uncommon for your Raven to be disconnected from TELUS after an
extended period of inactivity. This is generally a feature intended to reduce your
charges for inactive use.
Keepalive is used to test and maintain the Raven’s connection to TELUS by pinging an IP address after a specified period of inactivity. Keepalive is recommended
for users who have a remote terminated modem that infrequently communicates to
the network. Keepalive is also recommended if you have experienced issues where
the modem can no longer be reached remotely.
When Keepalive pings the IP address, an acknowledgement indicates there is an
active connection to the network. If the modem does not receive a response from
the IP address, it will retry 5 times in 5 second intervals. The
the radio module after 5 failed attempts and reconnect to TELUS.
Raven will then reset
Configuring Keepalive
As with all other aspects of the Raven’s configuration, you can use Wireless Ace or
Wireless Ace Web (page 11), AceNet (page 12), or direct serial communication or
Telnet (page 55) to configure Keepalive.
TELUS CDMA/1xRTT Raven User Guide Version 2.09 20
Keepalive
To set the Keepalive using Wireless ACE, select Other from the menu on the left.
FIGURE 1. Keepalive Configuration in Wireless ACE
*IPPING sets the interval, in minutes, you want Keepalive to test the network connection. To disable Keepalive, set *IPPING to 0 (default setting).
*IPPINGADDR sets the IP address you want to use for the test. If *PPINGADDR
is left blank or is set to an invalid IP address (i.e. an IP which is unreachable or one
which is not a valid IP address), the modem will reset itself on a regular interval.
*IPPINGFORCE sets whether you wish the network connection test to occur only
if there is no activity. Set to 1, IPPINGFORCE will force the ping to occur at the
IPPING interval regardless of any oth e r network activity. When *IPPINGFORCE
is set to 1, the modem does a complete modem reset, in addition to resetting the
connection. When the modem is reset, it could take a few minutes to reconnect to
the network.
Data usage using Keepalive.
When using Keepalive, be aware that a ping moves approximately 66 bytes of data
over the network and is billable by the carrier. The following *IPPING settings
will incur approximate monthly data usage in addition to any other data usage:
• 5 min. will use 1.2mb / month
• 15 min. will use 400k / month
• 30 min. will use 200k / month
• 60 min. will use 100k / month
• 120 min. will use 50k / month

CHAPTER 7 Host Modes
The Raven can be in one of six communication modes as the Host to the computer
or other device attached to the serial port of the Raven.
AT: The Raven accepts and responds to standard, Hayes-style AT commands. This
is enabled by default.
PassThru: Direct connection to internal hardware (OEM Module) of the Raven.
PPP: The Raven uses PPP to communicate.
SLIP: The Raven uses SLIP to communicate.
UDP P AD: Any data received on the serial port is assembled into UDP packets and
send to the session's associated IP and Port (described later). Any responses
received from the associated IP and port destined for the modem's Device Port are
unwrapped and sent out the
TCP P AD: Any data received on the serial port is packaged into TCP messages and
sent to the associated connection's IP and Port (described later). Any data received

expires.
If the modem is in any mode other than AT or PassThru, the AT command mode
can be re-entered by:
• Deactivating DTR (if &D2 or Ignore DTR, S211, is not set).
• Issuing the +++ escape sequence (if Disable AT Escape, DAE, is not set).
• Resetting or Power cycling the modem.
PassThru Mode can only be exited by resetting the modem.
Note: DTR needs to be asserted (S211=1 or &D0) by the host before PPP
Mode, SLIP Mode, UDP PAD Mode, or TCP PAD Mode can be entered.
AT Mode
AT commands are used to configure the modem, command it to do something, or
query a setting. For a full listing of the AT commands, refer to
AT commands must always be terminated by <CR> (ASCII character 0x0D).
If E=1 (Echo On), the AT command (including the terminating <CR>) will be
displayed (output) before any responses.
Two settings affect the format of AT command output: V (Verbose) and Q (Quiet).
If Q=1 (Quiet On), no result codes are output whatsoever, so there is no
response generated by a (non query) command.
If Q=0 (Quiet Off), result codes are output. The format of this output is then
affected by the Verbose setting.
If Quiet mode is off, the result code is affected as follows:
For V=1 (Verbose mode), the textual result code is surrounded by <CR><LF>
and any AT query response is also surrounded by <CR><LF>.
