* Issues with installing software driver
By Steve Blass
Q: I have a Novatel Merlin 620 CDMA-EVDO cellular data card for my laptop that stopped working recently after a software upgrade failed part way through. I tried to uninstall the software driver to reinstall it but the uninstaller program failed with an error message and now I’m stuck. Now when I try to run the installer from the original CD I am only offered an option to remove the software, and that fails too. What can I do besides reformatting my laptop and starting from scratch?
A: Start by looking in the Add/Remove Programs section of the Control Panel for an item called V620 and remove that. It is part of the software stack for the Merlin 620 card. Then get a copy of CCleaner and use that to clean up your system and registry.

* Getting an Adtran videoconferencing system to work again
By Ron Nutter
Q: My company owns several videoconference units that connect to a ISDN PRI T1. Several users reported problems with making and receiving video calls. The person who put this in has since left the company and, you guessed it, didnt leave much documentation behind. After tracking the wiring down, all the ISDN connections end up at an Adtran Atlas 830 unit which connects to the ISDN PRI. Any suggestions to where I should start looking?
A: The first thing I would suggest, since everyone is having problems, is to look at the ISDN PRI itself. If the Adtran 830 isn’t showing any problems, it wouldn’t hurt to call the LEC that is providing the ISDN circuit and have them take a look at it. While you have them on the phone, verify the exact type of ISDN Switch that you are connecting to at their end. If you hear the word “remote” used in the description, find out exactly what device you finally end up at and that it is the one that you need to configure your Adtran to talk to.
