Problem with your computer or application software or incompatible local or toll telephone company.

Carefully monitor the B1 and B2 LEDs while attempting a call. These LEDs flash during call establishment and then remain green or amber once the connection is established.

If neither LED flashes, ensure that your computer is turned on and operational, and that your application software has sent an AT dial command in the proper format.

There may be an incompatible local or toll telephone company. Contact your local telephone company and have it verify that you can dial a data call to the destination telephone number.

Send the command AT\S and check the cause code field.
