Cisco Residential Wireless Gateway Model
DPC3848/DPC3848V/DPC3848VM
Looking for a multifaceted, high-performance home and small office gateway that
combines a cable modem, router, and wireless access points in a single device?
You’ve found it in the Cisco
cost-effective networking solution provides a faster connection to the Internet by
incorporating 24 bonded downstream channels along with eight bonded upstream
channels. Bonded channels can deliver downstream data rates of up to 900 Mbps and
upstream data rates up to 170 Mbps. That’s up to 24 times faster downloads than
conventional single-channel DOCSIS® 2.0 cable modems.

Residential Wireless Gateway Model DPC3848. This
The Cisco Residential Wireless Gateway Model DPC3848 (Figure 1) is designed to meet DOCSIS 3.0
specifications and provide backward compatibility for operation in DOCSIS 2.0, 1.1, and 1.0 networks.
Figure 1. Cisco Residential Wireless Gateway Model DPC3848
This Cisco 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 provide a single high speed public Internet connection and allow users to 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 web sites.
