The EPC2203 is designed to meet Euro-PacketCable 1.0 and Euro-DOCSIS 2.0 specifications and is backward compatible with Euro-DOCSIS 1.1 and Euro-DOCSIS 1.0 networks. The EPC2203 uses advanced line interface technology to provide multi-country toll-quality telephone service using existing in-home wiring. The EPC2203 supports full 5 REN phone loading on each phone line (10 REN total). The EPC2203 provides two standard voice codecs: G711 and G728. Additional CODECs are available through software upgrades including high fidelity CODEC options for Toll Quality Plus service. Standard VoIP call signaling is compliant with Euro-PacketCables (MGCP/NCS) specifications. Software upgrades are also available to support Session Initiation Protocol (SIP) call signaling. WebWizard To facilitate setup and troubleshooting, the EPC2203 includes WebWizarda browser-based user interface. In addition, the seven LEDs on the front panel provide an informative and easy-to-understand display that indicates cable modem status and real-time data transmission activity. Battery Backup (Optional) The EPC2203 can be ordered with an optional housing that has provisions for an internal cartridge-style Li-Ion battery to provide backup power in the event of an AC power failure. The battery compartment is neatly concealed on the bottom of the unit. This user-friendly design allows easy battery cartridge replacement without the use of any tools.
