Cisco Model DPC2203 Cable Modem with Embedded MTA
The Cisco®Model 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.

Features
Standards Support
●Designed to meet PacketCable 1.5, PacketCable 1.0, and DOCSIS 2.0 specifications
●Backward compatible with DOCSIS 1.1 and DOCSIS 1.0 networks
Design and Function
●Attractive compact design and versatile orientation to stand vertically, lie flat on the desktop,
or mount easily on the wall
●Front panel LEDs provide visual feedback of real-time data transmission and cable modem
status
●Color-coded connectors and cables for easy installation and setup
Connections
Bridged 10/100BASE-T auto-sensing/auto-MDIX Ethernet port and USB 1.1 data port provide high-
speed data connectivity
VoIP Support
●Cable modem with an Embedded MTA that provides two lines of voice services
●Toll-quality, high-compression, and high-fidelity (exceeding toll quality) CODEC options
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)
Battery Backup (Optional models only)
The DPC2203 can be ordered with or without the capability to provide battery backup powering.
Units with battery backup capability are available in housings that have either one or two battery
bays. Each bay holds a single, user replaceable, rechargeable Li-Ion battery cartridge that
provides backup power in the event of an AC power failure. 1
1The listed battery backup time (8 hours) is the nominal initial time that the battery pack can provide standby power after
loss of AC power and after fully charging the battery. Due to variations in individual units, the actual initial standby time
can vary +/- 10%. Other factors can also influence battery standby power times such as CPE data activity, variations in
DOCSIS traffic, telephone port activity, battery aging, and temperature.
