Cisco Model DPC2425 DOCSIS 2.0 Wireless Residential

Gateway with Embedded Digital Voice Adapter

The Cisco® Model DPC2425 DOCSIS 2.0 Wireless Residential Gateway with Embedded

Digital Voice Adapter (DPC2425) is a high-performance home gateway that combines a

cable modem, two-line digital voice adapter, 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 DPC2425 has been designed to meet PacketCable™ 1.5 and DOCSIS® 2.0 specifications. In

addition, the DPC2425 is fully backward compatible for use on both DOCSIS 1.1 and DOCSIS 1.0

networks.

(image may vary from actual product and specification)

Designed for the active digital home or office, the DPC2425 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 the user’s home or office to the

wireless residential gateway.
