The new HSSI network module for the Cisco 3620 and 3640 routers enables customers to leverage their investment in the Cisco 3600 series by allowing them to affordably extend their bandwidth connectivity at an affordable price. The flexibility of the Cisco 3600 platform, combining dial access, LAN-to-LAN services, and routing with its multiservice integration of voice, video, and data, makes it an ideal choice to support HSSI applications.
