Adtran Express 3000 Standalone ISDN Ta with 2 Phone Ports

Summary: VERY GOOD ISDN T/A (MODEM)
Review: I have used three different brands of ISDN T/A modems and the Express 3000 beats Eicon Diva by a small margin. Both of the modems provide consistent trouble-free service but Adtran edges out Eicon in installation and speed.

Adtran installation process requires that the user knows how to use a keyboard and mouse. Installing the Diva is a roller coaster ride because some little or major problem occurs nearly every time.

You also have to reload Eicon's software once every forty-five days for no apparent reason, except the modem will not work. I cannot remember ever reloading Adtran software.

Over the past six years, I have probably used 10 or more Diva modems but less than 10 Adtran Express 3000. Neither modem tolerates any type of power surge, spike or lightning and once the modem is hit, it cannot be repaired.

Eicon does provide better customer and technical support because Adtran really does not offer technical support. Adtran tech support consists of advice when the unit is being installed. Adtran is not helpful if the unit develops any type of problem.
