The Cisco 700 series ISDN router provides affordable, fast Internet access for every PC in a small office. It is recommended for small offices and home offices of up to five users.Small offices that want to provide Internet access for every PC can use a single Cisco 700 and ISDN line, instead of multiple modems or TAs and multiple phone lines. Companies who choose to upgrade to ISDN with a Cisco 700 series router will increase the speed of their traditional analog modem connection by a factor of five.
