The Cisco Model EPC3212 EuroDOCSIS 3.0 8x4 Cable Modem with Embedded Digital Voice Adapter (EPC3212) is a high-speed cable modem with an embedded digital voice adapter. The EPC3212 provides a faster connection to the Internet by incorporating eight bonded downstream channels along with four bonded upstream channels. These bonded channels deliver downstream data rates in excess of 440 Mbps. That's up to eight times faster than conventional single-channel EuroDOCSIS 2.0 cable modems. The EPC3212 uses advanced line-interface technology to provide multi-country, toll-quality, telephone service using existing in-home wiring.
