* The Cisco 877-M routers are asymmetric digital subscriber line (ADSL/ADSL2+ Annex A & Annex M) over plain old telephone service (POTS) routing devices. The routers have an integrated 4 port Ethernet switch for the LAN and an ADSL physical interface for the WAN, allowing the routers to connect a corporate telecommuter or small office to corporate LANs and the Internet.

* The Cisco 877 Integrated Services Router extend the high-performance Cisco Integrated Services Router capabilities of running secure concurrent services, including firewall, VPNs, at broadband speeds to small offices. Easy deployment and centralized management features enable the Cisco 877 to be deployed in small office or teleworker sites as part of an enterprise network, by small to medium business customers for secure WAN connectivity, or used by service providers to offer business-class broadband services.
