The Cisco® Residential Wireless Gateway with Digital Voice Model DPC3928 is a high-performance home gateway that combines a cable modem, two-line digital voice adapter, router, and 802.11n wireless access point(s) in a single device, providing a cost-effective voice and networking solution for both the home and small office. The Cisco DPC3928 provides a faster connection to the Internet by incorporating eight bonded downstream channels and four bonded upstream channels. These bonded channels can deliver downstream data rates in excess of 400 Mbps and upstream data rates in excess of 120 Mbps. That's up to eight times faster downloads than conventional single-channel DOCSIS® 2.0 cable modems.

The Cisco DPC3928 (Figure 1) is designed to meet PacketCable™ 1.5 and DOCSIS 3.0 specifications, as well as offering backward compatibility for operation in PacketCable 1.0 and DOCSIS 2.0, 1.1, and 1.0 networks.

Figure 1. Example of Cisco Residential Wireless Gateway with Digital Voice Model DPC3928

The Cisco DPC3928 integrated router features a Dynamic Host Configuration Protocol (DHCP) server, Network Address Translation (NAT) and Network Address and Port Translation (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 in the home network by attaching multiple wired and wireless devices in the active home or office to the wireless residential gateway.
Consumer-friendly features like 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.
