The Cisco® Model DPQ3212 8×4 DOCSIS 3.0 Cable Modem with Embedded Digital Voice Adapter (DPQ3212) is a high-speed cable modem with an embedded digital voice adapter. The DPQ3212 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 340 Mbps. That’s up to eight times faster than conventional single-channel DOCSIS® 2.0 cable modems.
