Chapter 4 – Troubleshooting and Frequently Asked Questions

Frequently Asked Questions

Which providers can I use?

Two major providers are T-Mobile and Cingular.

We are Cingular approved.

Does this modem support High-Speed Circuit-Switched Data (HSCSD)?

No, our EDGE modems do not support HSCSD.

The modem is answering, but seems to not be doing anything?

The modem is answering in voice mode.

If you are trying to make a data call, make sure the account has CSD service. You will also need the data number (separate number from the main phone number that is provided by the provider).

I am trying to make a data connection by dialing from my wireless modem to an analog modem. Why does the analog modem answer and send tones, but never connect?

To make a data call you must use the ATD<number> command.

Make sure the account has CSD service.

How do I get the voice portion to work so I can talk to others using the wireless modem?

You will need a cable that has the speaker pins connected to a speaker and microphone.

We have a “Y” cable that splits out to a RJ9 connector that can be used to plug into the receiver of a handset.

‘ATD<number>;’ will originate a voice call.

How do I make an Internet connection to my dial-up ISP?

Make sure you have CSD service.

Create a dial-up connection to the ISP’s access number, then use your account username and password and choose the wireless modem as the device.

How does faxing work?

EDGE modems support Class 1 Group 3 faxing.

You will need fax services setup on your account. You should receive a separate phone number for fax; just like voice and data, and you must call the fax number for the modem to receive a fax.

You will also need fax software (we do not have working software). WinFax Pro Version 10 has been tested with some success.

I can’t make outgoing calls. I just receive a NO CARRIER response.

Make sure the antenna is connected and SIM is inserted correctly.

Check signal and registration: ‘AT+CSQ’ (10-31 is good), ‘AT+CREG?’ (0,1 is registered & 0,5 is roaming).

Check NO CARRIER reason with ‘AT+CEER’. Look up error code in Reference Guide.

The modem will not answer.

To have modem autoanswer, set modem 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 modem to ignore DTR, ‘AT&D0’, if you aren’t providing DTR.

I am trying to make a GPRS/EDGE connection using a Windows dial-up session. It connects and then immediately disconnects.

Make sure the APN is configured in the modem correctly (The APN is provided by the provider).

Check the APN with ‘AT+CGDCONT?’ To make sure it is correct.

If no APN is inserted, then insert the correct APN using the command ‘AT+CGDCONT=1,”IP”,”<APN>”’ with HyperTerminal or add it into the “Extra Initialization Commands:” in the modem’s properties.

Make sure the APN is correct for your account.

When I try to establish a GPRS/EDGE connection using Windows dial-up I get an error: “Hardware Failure”.

Check the modem to make sure it is installed and can be queried in the modem’s properties.

Make sure the com port is not being held by another application. Look for the TR light indication. If it is on, most likely another application is holding onto the port.

Make sure the dial-up connections maximum speed matches the modem’s properties maximum port speed.

Try rebooting the PC.
