The Cisco Model DPC3825 8x4 DOCSIS 3.0 Wireless Residential Gateway (DPC3825) is a high-performance home gateway that combines a cable modem, router, and wireless access point in a single device providing a cost-effective voice and networking solution for both the home and small office. The DPC3825 provides a faster connection to the Internet by incorporating eight bonded downstream channels along with four bonded upstream channels. These bonded channels can deliver downstream data rates in excess of 340Mbps and upstream data rates in excess of 120Mbps. That's up to eight times faster download than conventional single-channel DOCSIS 2.0 cable modems.The DPC3825 is designed to meet DOCSIS 3.0 specifications, as well as offering backward compatibility for operation in DOCSIS 2.0, 1.1, and 1.0 networks.Designed for the active digital home or office, the DPC3825 integrated router features a Dynamic Host Configuration Protocol (DHCP) server, Network Address and Port Translation (NAT/NAPT) and a Stateful Packet Inspection (SPI) firewall. These features allow the user to share a single high-speed public Internet connection as well as share files and folders between devices within the home network by attaching multiple wired and wireless devices in your home or office to the wireless residential gateway.Consumer-friendly features such as Wireless Protected Setup (WPS) and user-configured parental control can protect the home network from unwelcome intruders and family members from access to undesirable websites.
