Cisco (Cisco Systems, Inc. ) : Cisco 677

SOHO/Telecommuter ADSL Router

The Cisco 677 Small Office Home Office (SOHO)/Telecommuter asymmetric digital subscriber line (ADSL) Router provides a 10/100BaseT interface for connection to an Ethernet LAN. The Cisco 677 supports a robust routing feature set for seamless integration of ADSL service into corporate or home LANs and 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.
