Cisco Model EPC3208G EuroDOCSIS 3.0 8x4 Cable
Modem with Embedded Digital Voice Adapter
The Cisco®Model EPC3208G EuroDOCSIS™3.0 8x4 Cable Modem (EPC 3208G) is a
high-speed cable modem with an embedded digital voice adapter and router for use in
the home and small office. The EPC3208G 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 440
Mbps and upstream data rates in excess of 120 Mbps. That’s up to eight times faster
downloads than conventional single-channel EuroDOCSIS 2.0 cable modems.
The EPC3208G is designed to meet EuroPacketCable™1.5 and EuroDOCSIS 3.0 specifications,
as well as offering backward compatibility for operation in EuroPacketCable 1.0 and EuroDOCSIS
2.0, 1.1, and 1.0 networks.
Figure 1. EPC3208G EuroDOCSIS 3.0 8x4 Cable Modem with Embedded Digital Voice Adapter (image may
vary from actual product and specification)
The EPC3208G 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 in the home or small office network by attaching multiple
wired devices to the cable modem.
