E-Line package support in E-MTA

The exponential growth of packet-based data networks has led to an increasing demand for VoIP. Although VoIP was initially intended to bypass costly international tolls, this technology has since matured to the point where its voice services are comparable to those offered by the PSTN. To compete with satellite and telephone companies, cable operators are working towards incorporating VoIP into their infrastructure. However, in order to support VoIP, new protocols must be introduced. The protocol responsible for relaying information regarding the provision of voice services is the call signaling protocol. The information that is relayed via this protocol is categorized into packages, with each package being designed to support a specific service. The E-Line package is an analog access line package designed for supporting international telephony services. This thesis project focuses on the successful design and implementation of a subset of the E-Line package on Broadcom's VoIP residential broadband gateway.
