Phone Numbers for the Wireless Modem
• Every wireless modem will have its own unique phone number.
• The phone number will be given to you by your wireless service provider. Wireless provider implementations
may vary.
Examples of Useful AT Commands
A Note About HyperTerminal
In order to verify signal strength and roaming status, you must use a terminal application such as HyperTerminal. To
open this program in Windows XP or Windows 2003, go to Start > All Programs > Accessories > Communications
> HyperTerminal. Other Windows operating systems have similar paths to HyperTerminal. See your system’s online
Help if you cannot find it.
A Note About AT Commands
CDMA commands is included on the MultiModem CD and on the Multi-Tech Web site.
The following two commands let you query signal strength and roaming status.
Verifying Signal Strength
Using HyperTerminal, type AT+CSQ
The modem responds with the received signal strength (rssi) and bit error rate (ber).
BER values are always 99.
RSSI ranges are from 0 to 31.
Signal Strength Verification – RSSI
10 - 31
0 - 9
99
Sufficient
Weak or Insufficient
No signal
Note: Modems provisioned for the Sprint network have a different range of values for signal
strength. See the AT Command guide for details.
Checking Network Registration and Roaming Status
In this procedure, you will verify that the Wireless MultiModem has been registered on the wireless network.
Using Hyperterminal, type AT+CREG?
The modem will respond in one of the following ways:
Network Registration Verification
Value
0,0
0,1
Network Registration Status
The modem is not registered on any network
The modem is registered on the home network
The modem is registered on a network and it is roaming
0,5
Note: If the modem indicates that it is not registered, verify the signal strength to determine if the problem
is the strength of the received signal.
Checking the Modem’s Identity
Use the ATI command (Note: This command is illustrated using the capital letter i after AT)
• Type ATI0 (Note: The command ends in a zero)
The manufacturing data displays. For example, xxxxx Modem 800 1900
• Type ATI3
The software version displays. For example, S/W VER: xxxxx
• Type ATI6
The capability data displays. For example, +CGSM, +CIS707, ...

Establishing a Circuit-Switched Data (CSD) Connection
A Circuit-Switched Data Connection makes the wireless modem work like a regular analog modem. You must
have CSD service in order to make a CSD call.
Establish a Connection: Using HyperTerminal or a terminal application, you can establish a CSD
connection by entering the following command: ATD<phone number>
Notes:
• The phone number you are calling is entered between the displayed
brackets. Do not type additional brackets. For example, type only ATD
8585551212. 8285551212 is typed between the brackets.
• This command tells the modem to inform the wireless network that you are
initiating a CSD modem call. If you are dialing to another modem, the
remote modem should answer and a connection between the two modems
will be established. If you include a semi-colon (;) at the end of the dialing
string, the modem will instead initiate a Voice call to the phone number
dialed.
Disconnect:
Type: +++
Wait about two seconds to see an OK response.
Then type: ATH
Note: +++ is the escape sequence and ATH is the Hang-up command.
Answering a Circuit-Switched Data (CSD) Connection
A Circuit-Switched Data Connection makes the wireless modem work like a regular analog modem. You must
have CSD service in order to answer a CSD call.
Establish A Connection: Using HyperTerminal or a terminal application, enter the following command:
AT+CICB=0 <cr> This sets the modem to answer in data mode.
Then, call into the modem by dialing the number provided by your carrier.
Answer a Call:
When you see the RING responses on the terminal screen, enter ATA <cr> to
answer the call.
Set Auto-Answer:
Enter ATS0=x
This sets the modem to auto-answer. The call will be answered after the number
of rings entered. x stand for the number rings.
Then call into the modem by dialing the number provided to you by the carrier.
Disconnect:
Type: +++
Wait about two seconds to see an OK response.

Internet Access
Internet access can be setup in Windows Dial-Up Networking (DUN) of the computer that the wireless modem is
serving. Setup procedures will vary according to the type of wireless service provider used. To access Dial-Up
Networking on your PC, go to Start > Settings > Network Connections.
• For point to point data, a circuit-switched data connection is used. The user can set up DUN to make a
conventional V.32bis modem connection to any terminating modem at the other end. The phone number
specified in DUN can be one supplied by the wireless service provider or another phone number related to
a different dialup modem service (e.g., a dialup modem service phone number from any commercial or
private dialup network).
• For CDMA 1x data, a single DUN number is generally used by all of a wireless provider’s subscribers
throughout its area of coverage (regional, nationwide, continental, etc.). Rather than being a literal phone
directory number, as in conventional DUN, this is a code that gives the modem Internet access. Normally,
this phone number is #777.
Connecting to the CDMA Network for Internet Access
You will establish an Internet connection through a Windows dial-up session.
Note that your wireless provider will charge you for data usage.
Requirements
• One Multi-Tech wireless CDMA USB modem
• The modem must be getting a proper signal and be showing a network registration through the wireless
provider’s network
• A PC running Windows XP or 2003 with the Multi-Tech drivers installed for your particular model
The following instructions are for Windows XP SP2 and Windows 2003. Every PC may have slight
differences which may cause the instructions to be different. Use these instructions as a guide to help you
understand what is required to set up an Internet connection through your wireless service provider for all
operating systems.
Note: Cellular providers provide Internet services as part of your service plan. Multi-Tech recommends that if
you plan on using large amounts of data, to sign up for an unlimited data service plan with your provider.
Multi-Tech Systems, Inc. will not be responsible for any charges on your cellular bill. If you have any
questions about billing, service plans, service charges, etc., please contact your provider for more
information.

Chapter 4 – Troubleshooting and Frequently Asked Questions
Frequently Asked Questions
I just received this modem, what do I need to do?
•
•
•
•
You will need to call a carrier and register the ESN number with them. Sprint models (N2) must call Sprint
and Verizon models (N3) must call Verizon. Other models, N1 and N4, must contact their provider.
You must then activate the modem: We have Sprint and Verizon models that are preconfigured and just
needs to run through the activation steps.
The N1 models will need more configuration using AT commands in the Reference Guide. If that doesn’t
help, they may need to use the WPST provisioning tool.
The N4 model uses a RUIM card, similar to a SIM card.
Who are the carriers?
•
Sprint, Verizon, and Alltel.
I have the N1 model and I can’t get it activated on my carrier’s network.
•
•
•
You will need to configure the MDN, MIN, and maybe more settings such as the primary and secondary
channels, and the Home SID and UID.
The commands are: +WMDN (MDN), +WIMI (MIN), +WPCC (Primary channel), +WSCC (Secondary
channel), +WSID (SID and UID), and +WCMT=1 (to store changes)
You may need more settings set, so you may need to use the WPST provisioning tool application.
Note: N1 models are usually used for developmental purposes, so the customer will usually be working with a
carrier to get this activated on their network. It is always best for the customer to be working with the carrier
when they are activating a N1 model.
I activated my modem but I can’t do anything with it. When I try to dial out, I get a NO CARRIER response.
•
If you are receiving a NO CARRIER response, send ‘AT+CEER’ to check the reason for no carrier, then
check the number in the Reference Guide.
•
•
Make sure the modem is registered and getting good signal: AT+CREG and AT+CSQ.
Make sure the modem is activated and provisioned correctly.
I am trying to activate my Sprint modem. When I do the ‘AT+WIOTA=1’, I get an error of 1012 back.
•
Please check with Sprint to make sure your ESN, MDN, and MSID are correct. Also, make sure that the
MDN and MSID were inserted correctly into the modem.
How do I originate a voice or data call?
•
•
‘ATD<number>;’ for voice call.
‘ATD<number>’ for data call.
Why does the modem answer and then do nothing?
•
•
•
The modem is answering in voice mode.
If you want to answer a data call, make sure the account has CSD service.
You will need to set ‘AT+CICB=0’ to make the modem answer in data mode.
When I try to make a data connection by dialing to my analog modem from the wireless, why does the analog
modem answer and send tones, but never connect?
•
•
Make sure you are using the correct dialing string. You must send ‘ATD<number>’ for a data call.
Make sure the account has CSD service.
How do I get the voice portion to work so that I can talk to others?
•
•
You will need a cable that has the speaker pins connected to a speaker and mic.
We have a “Y” cable that splits out to a RJ9 connector that can be used to plug into the receiver of a
handset.
•
Verizon modems currently do not support voice.

Chapter 4 – Troubleshooting and Frequently Asked Questions
When I try to make a data call using ‘ATD<number>’, I get a NO CARRIER response.
•
•
•
•
•
Check ‘AT+CEER’ for NO CARRIER reason and look it up in Reference Guide.
Check the number that you are dialing.
Make sure you have CSD service.
Check registration and signal to make sure modem is registered and getting good signal: +CREG, +CSQ.
Make sure you went through the activation procedures correctly.
How do I make a CSD dial-up connection in Windows to my ISP?
•
•
Create a dial-up connection to the ISP’s access # and use the correct password and username.
You must have CSD service.
Does this modem support High-Speed Circuit-Switched Data (HSCSD)?
No, our CDMA modems do not support HSCSD.
•
The modem will not answer.
•
•
•
Set the modem to autoanswer with ‘ATS0=1’ and ‘AT&W’ to store the setting.
Send ‘ATA’ to the modem once the RING is indicated on the terminal screen.
You may need to set the modem to ignore DTR, ‘AT&D0’, if your system doesn’t provide DTR.
The modem answers, but does nothing.
•
•
•
Modem is answering in voice mode.
Voice: Need a voice cable; such as our “Y” cable.
Data: Make sure you set ‘AT+CICB=0’ to make the modem answer in data mode.
How does faxing work?
•
•
•
•
The CDMA modems only support Class 2.0 Group 3 faxing.
Need fax services setup on the account.
Need fax software that supports the modem; e.g., WinFax Pro v10.0.
Need to set ‘AT+CICB=1’ for modem to answer in fax mode.
When I set the S0 command, store it with &W; then send “ATZ” to the modem, the command goes back to
the default of 0?
•
This is a bug in the modem. S0 will store just fine, as long as “ATZ” doesn’t get sent to the modem.
After I set the E and &D commands followed by &W, it looks to be stored okay, but as soon as I recycle
power on the unit the E and &D commands get set back to default of E1 and &D2.
•
This is a bug in the modem. These commands will not store correctly. If modems are powered back up and
an “ATZ” is sent to the modem, then &D and E will load to your stored settings correctly.
Firmware versions 210 and above fixes the storage or the E command.
•
After I set the Q, V, and &S commands followed by &W, if I recycle power or send ATZ to the modem the
settings will get set back to default.
•
Bug in the modem. These commands will not store.
What is the max supported serial baud rate?
230,400 bps is the max.
