Paper Abstract

Telecommunications service providers (telcos) have long dreamed of offering the "Triple Play," i.e., bundled voice, data and video services, including high-definition digital broadcast and on-demand video services. However, until recently, telcos have been unable to offer Triple Play services due to technical obstacles, including bandwidth limitations in their access networks and the high cost of Triple Play CPE devices. Recent deployments have demonstrated that passive optical networks (PON) can be cost-effective and can reliably support the transmission of high-speed data in excess of 100 Mbps per subscriber, which is sufficient to support Triple Play services. Additionally, innovations in semiconductor device technology have dramatically decreased the cost of Triple Play CPE. With the realization of a robust, flexible broadband access network and low-cost CPE that support data, voice and video services, what was once a dream is now possible. In order to make this dream a reality, PON protocol and voice services processor (VSP) system-on-chips (SoC) must be integrated into CPE devices that terminate the PON and enable the end-to-end delivery of data, voice and video services from the service provider to the subscriber's PC or other Internet appliance. These CPE devices, referred to as optical services gateways (OSGs), must cost-effectively support a wide variety of subscribers and applications, including detached single and multi dwelling unit structures.
