Abstract
This document defines a Dynamic Host Configuration Protocol (DHCP)
option that will be used to configure various devices deployed within
CableLabs architectures. Specifically, the document describes DHCP
option content that will be used to configure one class of CableLabs
client device: a PacketCable Media Terminal Adapter (MTA). The
option content defined within this document will be extended as
future CableLabs client devices are developed.

Cable Television Laboratories, Inc. (CableLabs) is a non-profit
research and development consortium that serves the cable television
industry via design and specification of new and emerging broadband
service architectures. Several CableLabs initiatives define DHCP
clients that have specific DHCP configuration requirements. One such
initiative is the PacketCable project.
The PacketCable project is aimed at architecting, qualifying, and
supporting Internet-based multimedia services over cable-based packet
networks. These new multimedia services will include telephony and
videoconferencing, delivered using the basic Internet Protocol (IP)
