CableLabs Defines a Converged Cable Access Platform

CableLabs issued a new technical report defining a new device that facilitates the evolution to a converged access network architecture. The report, which represents consensus requirements from Comcast, Cox, Time Warner Cable and other CableLabs members, consolidates core interface requirements previously referred to as CMAP and CESAR.


The Converged Cable Access Platform (CCAP) integrates the functions of broadcast and narrowcast quadrature amplitude modulators (QAMs), as well as DOCSIS 3.0 downstream and upstream interfaces. It also includes the option to support passive optical network (PON) termination equipment in the same chassis.


Through flexible provisioning of traditional video QAMs to DOCSIS QAMS, the CCAP will enable the efficient transition from traditional video transport to IP transport of managed video services.


CableLabs is working on specifications for configuration and management technology important for service reliability and operational efficiency.


"This blending of our two approaches will help create an industry-wide approach for access technology platforms," said Comcast Cable CTO Tony Werner. "We are engaged in this CableLabs process and are actively contributing to its efforts on CCAP," he added.
