Model DPC2203 Cable Modem with Embedded MTA

Description

The DPC2203 Cable Modem (DPC2203) is a high-speed cable modem with an embedded media terminal adapter (EMTA). The DPC2203 features two RJ-11 telephone ports for Voice over Internet Protocol (VoIP) service along with a 10/100BASE-T Ethernet port and a USB 1.1 port for high-speed data connectivity.

The DPC2203 is designed to meet PacketCable™ 1.5, PacketCable 1.0, and DOCSIS® 2.0 specifications as well as being backward compatible with DOCSIS 1.1 and DOCSIS 1.0 networks. The DPC2203 uses advanced line-interface technology to provide multi-country, toll-quality, telephone service using existing in-home wiring. The DPC2203 supports full 5 REN phone loading on each phone line (10 REN total).

The DPC2203 fully supports the CODECs specified in PacketCable 1.5. Additional CODECs are available through a software upgrade that includes a high fidelity CODEC option for toll-quality plus service. Standard VoIP call signaling is compliant with PacketCable’s (MGCP/NCS) specifications. Software upgrades are available to support Session Initiation Protocol (SIP) call signaling.

WebWizard

The DPC2203 includes WebWizard, a browser-based graphical user interface. WebWizard is a powerful tool that facilitates installation and troubleshooting by eliminating the need to load setup software on the customer premises equipment (CPE).
