Public Telephony via Mesh DAMA Systems

摘要

SCPC DAMA technology has been applied to both public and private voice and data networks. Typically, quite different network architectures are used to support different levels of applications. For instance, inter-exchange, or infrastructure, networks that connect public telephone switches may offer full mesh connections. But, SCPC DAMA VSATs that provide "last mile" local loop connections into PSTN Central Offices (CO's) usually rely on a "star" architecture that pusbes switching and routing functions out to terrestrial public network equipment. Ultimately, though, the infrastructure and local loop segments must play together in an integrated network delivering toll quality voice at the lowest possible recurring service cost. This paper presents an innovative network architecture that blends both infrastructure and local loop services into a single integrated, scaleable VSAT network that is ideally suited for PSTN service in developing and sparsely populated regions.
