ADSL Router Cisco 678

The Cisco 678 provides a 10/100BASE-T interface for connection to a small home office LAN or a single Ethernet-equipped PC. The Cisco 678 supports a robust routing feature set for seamless integration of ADSL service into corporate or home LANs/WANs. A built-in Dynamic Host Configuration Protocol (DHCP) server automatically assigns IP addresses to PCs on the LAN, and with port address translation (PAT) these PCs can share a single IP address. In addition, with Cisco no truck roll technology, plain old telephone service (POTS) splitters are not required at the premise, thus reducing the cost of installation.
