Unfortunately the modem you listed is not supported in Linux very well.
It's a winmodem which means that it has to have windows software to run it.
only way would be to get a different modem I'm afraid there is no easy way to make them work with Linux.
That is due to the fact that the makers do not release their software drivers for linux.
if you are feel you can do some work yourself to get it going it may be possible here are a couple of web pages that may help.
Although there is no guarantee. Good Luck.http://www.techrepublic.com/article/make-linux-connect-with-your-winmodem/1054996
