How to configure Tata Photon and data card to my Outlook 2007?

Outlook set up with data card, I am using Outlook 2007 in the office where we have a high speed internet connection. If I disconnect from the LAN, Outlook does not work. When I access my e-mail at home, Outlook Web Access must be opened. I have a Tata Photon+ data card and I would like to connect to it to access Outlook. Does anyone know how to configure Outlook to work with my Tata Photon card?
