Cellabs makes two products that allow you to access your office network
using a cellular phone. Both products tie into an existing cellular
phone between the handset and base unit.
* One product is Cellmodem 2400. If you don't have a modem, Cellmodem
2400 can provide both 2400 baud modem and Datajack capabilities in
one unit.
* Another product, Datajack, allows a cellular phone to work with any
internal/external modem you already have.
You can find the address and phone number for Cellabs in a separate
article in the Tech Info Library.
