WARNING
The antenna(s) used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be colocated or operating in conjunction with any other antenna or transmitter.
1 Introduction
The AirLink CDMA modem is designed to operate in CDMA networks. Two services
are available in the CDMA networks: 1xRTT, a packet switched connection, and IS95B, a circuit switched connection.
CDMA IS-95B
The AirLink CDMA modem is capable of making IS-95 connections. The modem first
connects to the CDMA network and the network then connects to the call to either
the Public System Telephone Network (PSTN), or to the Internet using QNC. These
calls use an Interworking Function (IWF) to bridge the CDMA network to the PSTN:
Internet
CDMA
Network
IWF
PSTN
For Internet connections, the Interworking function can use a special feature called
QNC (Quick Net Connect). The IWF provides a link to the Internet without going
through the PSTN. Establishing a standard point-to-point call requires the Airlink
CDMA to configure a modem at the IWF. It is the IWF modem that actually connects
to the PSTN and dials the number. Call progress is not directly available to the local
modem, although some information can be exchanged. When the IWF has completed
the handshake with the remote modem, the local modem is advised and the
connection is complete.

CDMA2000 1X
The AirLink CDMA modem provides data capability into the packet service offered
with CDMA2000 1X (1xRTT) technology. CDMA2000 1X offers higher speed data
operations than are available with IS-96 service. IS-95 is limited to 14.4 kbps. 1X
service uses a fundamental channel at 9600 bps and can add supplemental channels
when needed to boost speed to as high as 153.6 kbps on the downlink (network to
modem) and 76.8 kbps on the uplink (modem to network).
1.1 Product Overview
The AirLink Redwing CDMA is a rugged, full duplex 1xRTT CDMA modem that
provides wireless transport capabilities for fixed and mobile applications. CDMA is
an efficient and secure wireless technology that works well for fixed or mobile
applications.
The Redwing CDMA is ideally suited for fixed and mobile Industrial or Commercial
Applications, including Telemetry, SCADA, Public Safety, Mobile Dispatch, Field
Service, Financial Transaction Processing, and Security applications. The CDMA
Redwing enables virtually any PC, PDA, or networking device (router, server, etc) to
access the CDMA/1xRTT data network. The Redwing CDMA can also be used in
installations with many different types of Remote Terminal Units (RTUs),
Programmable Logic Controllers (PLC’s) or other computers that perform metering
and monitoring functions in the oil, gas, water, and transportation industries. The
Redwing CDMA can be a low-cost replacement for many existing landline, private
radio and circuit-switched cellular installations.

2 Network Connection Options
The AirLink CDMA Redwing is capable of offering multiple network connection
options. This section will illustrate the different network options that are available.
2.1 Internet (TCP/IP) Connections via 1xRTT
When using the Redwing CDMA, remote access to is done via a PPP (TCP/IP)
connection to the CDMA network. The CDMA carrier actually provides Internet
connectivity, and, therefore, it becomes the ISP for that session. Applications such as
web browsing, email, FTP, etc should work as they would normally.

2.2 Circuit-Switched CDMA Connections
Where there is carrier support for circuit-switched connectivity, the Redwing CDMA
is capable of providing traditional Circuit-Switched ‘dial-up’ communications.
Where you would normally use a landline modem or analog cellular dial-up device,
the Redwing CDMA can be a drop-in replacement. The CDMA carrier actually
provides basic connectivity to the Public Switched Telephone Network (PSTN), so all
that is needed is a CDMA activation (phone number) and connection of the serial
cable. For connection to Windows computers, follow the setup profile for a Hayes
Compatible or Standard 33600 baud modem. No special drivers or setup is required.
Practical Applications
Host Modem
The Redwing CDMA can be used as a modem connected to a host PC (or other device)
and provide dial-up connectivity to the Public Switched Telephone Network (PSTN).
Using the Hayes Compatible ‘ATD+Phone Number’ dialing sequence, the modem can
dial any landline telephone modem. The diagram below shows how the application
may be used.

Network
CircuitSwitched
Destinations
PSTN
Remote Modem
The Redwing CDMA can be used as a modem connected to a remote PC (or other
device) and provide two-way dial-up connectivity to the Public Switched Telephone
Network (PSTN). Using the Hayes Compatible ‘ATD+Phone Number’ dialing
sequence, the modem can dial or receive landline connections. The diagram below
shows how the application may be used as a remote device.

8. Type AT followed by [Enter]. You should receive an "OK" in response.
Other AT commands may now be issued to the modem. See Section 5 for a list of AT
commands
3.2 Modem Activation [Model C3111]
The activation process is unique for each carrier. See the appropriate CDMA Setup
Wizard on AirLink’s web site: www.airlink.com > Support > Downloads and Support
Documents > Modem Utilities.
3.3 Modem Activation [Model C3110]
The Redwing CDMA modem may be already set up to register online with a phone
number, etc. pre-configured into it (by AirLink Communications, Inc.). When a
modem is registered on the network and working, the lights will look like the
following:
Reset
eg x
Pw
Redwing CDMA
Note that the Reg light may be flashing at first. When it is registered on the
network, it will go solid. Also the Tx (transmit) and Rx (receive) lights will flash as
data is transferred to and from the modem on the network.
If your modem lights look like the above when the modem is powered on, you do NOT
need to configure the phone number, etc. into the phone and may skip this section.
AirLink Communications, Inc.
Page 7
September 14, 2004
Redwing CDMA User Guide Version 2.01
If however the Reg light does not go solid after a few minutes, your modem may
need to be configured with a phone number and other parameters. Or if you have
service ordered and a phone number for your modem, you may add these parameters
yourself by doing the following:
•
Connect up to configure the modem as in Section 3.1.
•
If you are unfamiliar with using AT commands, please review Section 5 first.
•
Enter the Lock code from your provider using AT~NAMLCK (as described
below).
•
Enter the phone number, System ID and Network ID with the
AT~NAMVAL command (described below). The parameters are saved
automatically once entered.
•
Reset the modem by pressing the Reset button on the front of the modem, or
power-cycle it.
The modem should now come online registered.
NAMLCK ("NAM Lock")
AT~NAMLCK=nnnnnn (nnnnnn = Lock Code from carrier)
Example: AT~NAMLCK=123456 - uses 123456 for the NAM Lock value
The NAM is the “Number Assignment Module”. The NAMLCK command
unlocks the ability to set the NAM parameters (to provision a an account).
~NAMLCK
The NAMLCK is the modem’s 6-digit OTSL (One Time Subsidy Lock), MSL
(Master Subsidy Lock), or SPC (Service Provisioning Code). The carrier
provides this number to you at time of service activation. If the number is
accepted by the modem, the OK result code is returned. If the number is
rejected, the ERROR result is returned. If three successive Errors are
returned, the modem must be reset to allow any further attempts.
Note: The modem permits 99 failures of this command during its
lifetime. After that, the modem becomes permanently disabled.

NAMVAL (“NAM Value”)
AT~NAMVAL=[,,,]
Examples:
1. AT~NAMVAL=0 - Sets NAM 0 as the active account
OK {Response}
2. AT~NAMVAL?0 - Queries the active account NAM0
NAM: 0
NUM: 8135551212
(10 digit phone number)
SID: 40
(System ID)
NID: 65535
(Network ID)
OK {Response}
3. AT~NAMVAL=0,8135551212,40,65535 - Assigns phone number
813-555-1212, a SID and NID to account 0.
~NAMVAL
The NAMVAL command has 3 functions:
Setting the Active Account index
The modem supports two accounts. One is always the ‘active’ account.
Using the parameter followed by a 0 or 1 will set the active account
to be used.
Reading the current account information
The query form of the command will report the details of the active
account:
Write account activation data
Following successful unlocking by ~NAMLCK, this command can be used
with all parameters to write the account data to the modem. If ~NAMLCK
has not been successfully executed, the modem returns ERROR. The
carrier will tell you what numbers to enter for NUM, SID, and NID. The
choice of NAMVAL is up to you. Following writing the values, the modem
must be reset.

4.2 Windows Dial-Up Networking (PPP) Configuration
This section describes how to setup a Windows Dial-up Networking connection using
an AirLink Redwing CDMA Modem. Windows 2000 Professional was used in this
example. The connection uses PPP to communicate to the modem and gain access the
Internet.
Before you start, you need the following:
Administrator privileges to the computer you are configuring or access
granted by an administrator on the network to add/remove devices to your
computer. (Not necessary on Windows 98/ME.)
A 1xRTT user account, password, and access number (obtained from your
CDMA Service Provider).
Windows COM Port and modem set up for a Standard 33600 Modem (see
Section 4.1).
No other program is to be running that is using the serial (COM) port that
your modem is attached to.
NOTE: If you have an existing LAN connection, then this dial-up connection to
your CDMA modem may interfere with your existing connection. Once the
connection is initiated it will take over as the "default route" for the majority of
your LAN traffic, specifically Internet access. It's recommended to disconnect your
LAN connection before using a PPP connection with your AirLink modem.
If however you want the two connections to co-exist, you can de-select "Use
default gateway on remote network" (described later) and you can use the route
command to setup routing through the modem properly. Go to a Command
Prompt and type route /? to find out more, or talk to your administrator.
Now that the modem has been added, the Dial-up connection must be created.
1. Select Start→ Settings→ Control Panel→ Network and Dial-Up
Connections.

5 Using AT Commands
This document is a reference for using AT commands with the AirLink Redwing
CDMA modems.
Use a terminal emulation program to connect up to the modem either locally (via the
serial port of a computer) or remotely (over an existing internet connection on a pc to
the modem at a remote location). Set up to connect to the modem by either method
described in Section 3.
Sample AT Commands
Here is an example of entering AT commands, changing some settings, saving and
resetting the modem. (Note that any command you are unsure of is explained in The AT
Commands section.)
Type AT and press Enter .
AT
You should get a response of "0" or "OK".
To turn on echo and verbose modes, type the following:
ATE1V1
You should see an "OK" response if Verbose Mode was properly activated (V1)
If you should see a “0” response, your modem is in Terse Mode and the V1 command did
not adhere. Try ATV1 again by itself if that happens. You should see an “OK” response.
To set the baud rate, use the +IPR command:
You should get an "OK" (if in Verbose Mode)
AT+IPR=115200
Note: HyperTerminal needs to be disconnected & reconnected after a baud
rate change.

~NAMVAL
The NAMVAL command has 3 functions:
Setting the Active Account index
The modem supports two accounts. One is always the ‘active’ account.
Using the parameter followed by a 0 or 1 will set the active account
to be used.
Reading the current account information
The query form of the command will report the details of the active
account:
Write account activation data
Following successful unlocking by ~NAMLCK, this command can be used
with all parameters to write the account data to the modem. If ~NAMLCK
has not been successfully executed, the modem returns ERROR. The carrier
will tell you what numbers to enter for NUM, SID, and NID. The choice of
NAMVAL is up to you. Following writing the values, the modem must be
reset.

5.5 Alphabetic List of AT Commands
Command
Description
+++
Escape Sequence (not preceded by AT) Used to exit data state and enter
command state; this is not preceded by AT and does not require . The
escape character is fixed as the plus sign “+” (0x2B). The guard time between
normal transmission data and the escape sequence is specified as 1 second and
cannot be changed. Therefore, the modem requires a minimum of 1 second of
inactivity on the serial input, three plus sign characters, followed by 1 second
of inactivity.
A/
Repeat Last command (not preceded by AT) Re-executes the last
command string entered. The previously executed command remains in
the command buffer until AT is entered or the modem is reset or powercycled. This command does not require the AT prefix or a at the
end. It executes immediately on entry of the slash character.
Answer – Manual
Instructs the modem to go off-hook and attempt to establish a connection
without waiting for a ring. This is used to answer an incoming call if
AutoAnswer (S0) is disabled. The command presumes a RING has been
received. If the command is issued without a RING, behavior depends on the
state. If in command state, the modem replies with OK and remains in
command state. Should the modem be in pass-through state without a call
pending, the Answer command is sent to the IWF modem. This typically goes
off-hook and looks for carrier. When none is detected, the NO ANSWER or
NO CARRIER result is returned. This is, however, dependent on the IWF
modem.
If the incoming call is a fax call, the modem must be configured for answering
fax via $QCVAD and set for fax mode using +FCLASS=2.0 prior to the RING
being received by the modem. This is due to the method of call setup on the
airlink between the IWF and the CMDA modem.
The modem looks for carrier to negotiate the connection, and either issues:
• CONNECT and enters data state; or,
• NO CARRIER and remains in command state.

Dial
Initiates a data/fax call. (Use +CDV to dial a voice call.) Because of the options
available in this command, another AT command cannot follow it on the same
line. All characters following the D command are taken as parameter options.
Several types of data and fax calls are possible based on the option(s) entered.
Packet Data calls Traditional CDMA data call dialing uses the parameter
“#19788”. This triggers the modem to try a 1xRTT connection if that service is
detected. It is possible that 1xRTT service may be detected in an area that offers
1X voice service, but only IS-95B (QNC) data service. In these situations the
call is likely to fail. You can force the modem to attempt one service type or the
other by using one of these dedicated parameters:
#QNC
Connect to QNC using IS-95B service
#19788 Connect PPP using 1xRTT service
D [options]
Async (CSC) Data/Fax
The type of call opened depends on the setting of +FCLASS.
The modem does not actually dial the number in the string. For an IS-95B call,
the dial string is passed to the IWF where a modem there issues the dial over the
PSTN. Prior to passing the dial command, the modem sends the IWF modem
the string defined in +CFG (Configuration String) to configure the IWF modem
for the call. For dialing an async data or fax call, the parameter string options
are included on one command line with or without spaces. There is a limit of 35
characters in the dial options string. Upon successful answer and connection,
the modem goes into data state. There is a time limit (Register S7 - Wait for
Carrier) for the process.
The options listed are commonly supported but specific IWF modem
capabilities govern the list of supported parameters.
Opt
Meaning
0 - 9 Any digit (0-9) (*, #, A, B, C, or D are also permitted).
The phone number may also include the formatting characters
brackets, (), hyphen -, and .
These characters are ignored.
Tone (DTMF) dialing - ignored by the modem.
Pulse dialing - ignored by the modem.
Wait for dial tone before processing the remaining characters in
the dial string. The duration of the wait is
limited by register S7
(Wait for Carrier).
Pause before processing the remaining characters in the dial
string.
The pause time is set by register S8 (Comma Pause
Time).
Wait for billing (bong) tone before processing balance of string.
Wait for quiet answer; limited by register S7 (Wait for Carrier).
Hook flash. Causes the modem to go on-hook briefly and then
returns to off-hook. This is used to access
certain calling features
on the PSTN.

On-line (Remote)
Causes the modem to go from command state (online condition) to data state.
The modem responds with the normal CONNECT response codes (if enabled)
as if the connection were new. This command is executed by the IWF modem.
If the CDMA modem was in an offline condition and without an airlink, the NO
CARRIER and OK result codes are returned. If the modem was offline and the
airlink was established (passthrough state) but without a call in place, the IWF
modem attempts to process the command. The typical result is either NO
ANSWER or NO CARRIER. This is, however, dependent on the IWF modem.

6 Using SMS Messaging [Model C3110]
Command
! CNTSMS
!GSMS
Description
! CNTSMS = Count message
Reports the number of messages stored in the modem as
follows:
New Urgent Msg {Index = 1}:
New Regular Msg {Index = 2}:
Voice Messages {Index = 3}:
The Index number corresponds to the SMS list index used to retrieve
messages. The counters n, r, and v indicate the number of messages in
each list.
When retrieving (!GSMS) or deleting (!DSMS), the message number is
base 0, so the highest message number in any list is the reported count
minus one.
!GSMS =Get SMS
!GSMS?
Read an SMS message from the modem. The message read is
determined by the parameters:
i index list (0, 1, 2)
m message number (base 1)
The message number is a base 0 index into the list, where 0 is the oldest
message, and the number reported by !CNTSMS minus one, is the most
recent message.
!SSMS = Send SMS
!SSMS=,,,[cb],""
!SSMS
AirLink Communications, Inc.
Send SMS
Sends an SMS message using these parameters:
opt service option 6 = send rate set 1, 14 = send rate set 2
p priority 0 = normal
1 = interactive
2 = urgent
dest destination # phone number of destination
cb callback # phone number for reply (this is optional) text message
body up to 160 bytes of data
The service option used depends on the carrier.
The text is enclosed in quotations. The quote character cannot appear in
the body text. Messages with over 160 bytes of body text will be
truncated by the modem and sent anyway.

A thermistor inside the modem (monitored by the modem CPU firmware) causes flow
control to be activated should the internal temperature reach 75ºC (167ºF) as
measured at the radio. Flow control is released when the temperature falls below 75.
Should the temperature of the radio reach 80ºC (176ºF), the modem terminates the
connection in order to protect components and avoid drifting outside radio
specifications.
