Introduction
The Model DPR2320, DPR2325, EPR2320, and EPR2325 cable modem
gateways are among the fastest cable modems available on the market
today. These cable modem gateways offer high-end performance and
unsurpassed reliability for both home and small office networking.
These cable modem gateways provide broadband network operators
with a cost-effective way to offer high-speed data services to

10/100BASE-T Ethernet port (4 ports on the DPR/EPR2325), a USB 2.0
port, and an 802.11g wireless access point to provide connectivity for
high-speed data wired or wireless services or other Internet devices.
This chapter provides an overview of the outstanding design and
performance features of the cable modem gateways, the front and back
panel components, and a theory of operation for cable modems. This
chapter also provides the requirements for the cable system and the
