This article reports that a growing number of independent operating companies are inheriting the debate over fiber-to-the-premises (FTTP) technologies, transforming what was once a hypothetical exercise in colorful diagramming into pragmatic decisions about the blood and bones of their own individual networks. About half the homes currently passed by FTTP networks in the U.S.--including both private and municipal networks--are passed by broadband passive optical networking which is based on Asynchronous Transfer Mode technology, according to research firm Render Vanderslice & Associates.

The bulky Class 5 switch currently hogging all the space in most central offices is no lean, mean fighting machine. As packet switching is introduced into telecom networks, the current power architecture-a highly concentrated arrangement in the central office-will spread itself into a much more modulated arrangement, with less power fueling the core of the network. Softswitches are already beginning to phase out Class 5 switches, while doser to the edge, access gateways are replacing remote switches.

Reports that Telcordia Technologies Inc. has been awarded a U.S. patent number for its method and system known as softswitch architecture for media connectivity over a packet-based network. Remarks from Michael Cook, vice president at SAIC, parent company of Telcordia, concerning the development of the softswitch architecture; Intention of Telcordia to identify potential licensees of its technology; Explanations concerning the technology likely used in other softswitch architectures.

The article discusses the possibility for the convergence of optical technology and packet technology. The author offers two possible scenarios that could lead to the convergence which include the integration of a simple optical technology into the packet layer and the integration of the packet technology into the optical layer. Operators lament about the difficulty of migrating optical transport organizations to Internet Protocol (IP)/Multiprotocol label switching (MPLS).

This article presents information on packet switching in telecommunication. Packet switching made ingenious use of lots of unused moments in any telephone call when tiny silences between words create holes during which the circuit is not carrying anything. Your speech into the phone is broken up into individual packets that go out into the system like a fleet of trucks carrying parts of what you say. The Internet works this way to transfer data across circuits that form a web. ARINC and other broadband services that emulate the Internet are moving packets..
