SUMMARY
Cisco 870 Series integrated service routers combine increased network performance with advanced security to allow small office customers to get the
most from their broadband connections. With models supporting different broadband technologies such as DSL, cable, and Metro Ethernet, the Cisco
870 Series can be deployed at any small office location. Optional integrated 802.11b/g wireless capabilities provide true business-class WAN and
WLAN access in a single solution. With Cisco 870 Series enterprise IT managers and service providers can take advantage of a solution that can be
easily set up at the remote site and then be centrally managed to reduce ongoing operational costs.
