  • Based Switchboard That Uses Internet Protocol This Means That Telephone Calls Are Made Through the IP Networks
    CHAPTER 14 FUTURE DEVELOPMENTS 14.1 Mobile Softswitch What is Softswitch? Softswitch is the software based telephone system or exchange, (PABX) that allows the transfer of voice over the Internet Protocol [131], i.e. Voice over IP. It is a PC-based switchboard that uses Internet Protocol This means that telephone calls are made through the IP networks. Currently, all the softswitches available enable call routing or forwarding only to fixed telephone lines. There is no functionality that enables call forwarding to mobile or cell phones. I am intending to investigate possibilities to extend the available softswitches to offer the call forwarding functionality to cell phones. That is the functionality that is not available with the current PABX s and Softswitches. The following section discusses mobile CCTV. 14.2 Mobile Close Circuit Television (CCTV) Security System Closed Circuit Television (CCTV) is a security system that enables monitoring of a particular area under the surveillance of a camera. Normally, there is more than one camera used to observe and watch the area. Most developments of these CCTVs are advanced and use digitized video images and use the desktop workstations to display the video content. Such systems do not make it possible for the security personnel to move around whilst watching the computer, for example. The moment he moves in front of the desktop workstation he would miss lots of happenings from the video; otherwise, he would have to playback the video. I am intending to investigate the possibilities to develop a system that allows surveillance over cell phones. With systems like mobile TV s begin developed, I do see a possibility of using the same types of technologies and devices that are used in such systems to develop a mobile CCTV.

  • The Lucent Technologies Softswitch— Realizing the Promise of Convergence Ramnath A
    ♦ The Lucent Technologies Softswitch— Realizing the Promise of Convergence Ramnath A. Lakshmi-Ratan The Lucent Technologies Softswitch was created as a result of Project Saras, which was initiated by two Bell Labs researchers. The purpose of Project Saras was to develop a software system that solves several major problems that providers of tele- phony services now face. Today’s public switched communications infrastructure con- sists of a variety of different networks, technologies and systems, most of which are still based on the wireline circuit-switched structure. The technology, however, is evolving to packet-based networks, and service providers need the ability to inter- connect their customers with these flexible and cost-effective networks without losing the reliability, convenience, and functionality of the public switched tele- phone network. The Lucent Softswitch, formerly known as the PacketStar† IP Services Platform, resulted from a focus on these needs. This Softswitch was initially marketed as a signaling-interoperability and services-creation platform under the umbrella brand name PacketStar for Lucent data networking products. It was renamed in light of the recognition that it represented an emerging concept in the industry called a “softswitch,” referring to a software-based distributed switching- and-control platform. This paper provides a high-level description of the Lucent Softswitch and its application to building next-generation converged networks. Introduction and Background The demand for communications services contin- ing to develop the communications infrastructures ues to explode and grow at an unprecedented rate. It that fuel their economies as they prepare to meet the is widely accepted that in just the next 15 to 20 years next millennium.

  • Packet Voice Solutions: IP Telephony Finds Its Market Calling
    No. 204 Page: 1 of 8 METRO SOLUTION Packet Voice Solutions: IP Telephony finds its Market Calling Abstract In the past, voice was king. The telecommunications infrastructure had been built to deliver toll-quality dial tone to anywhere in the world. Data traffic was the unloved stepchild and was forced to fit into the existing voice infrastructure. Revenue generated from voice service far exceeded revenue from data. The Internet has changed all that. Now data has overtaken voice not only in bandwidth use on carrier networks, but also in revenue generated for operators. Revenue for voice is also being squeezed by other providers such as mobile and cable operators. New investments in network infrastructure are being targeted at data rather than the voice needs. This makes business sense given the shift in revenue patterns. There is also more potential for incremental revenue from new data services such as storage networking, application outsourcing, and rich content streaming. In this Metro Solution Note we explore the opportunities that packet voice solutions can offer operators for new revenue-generating services. We will look at types of services that are possible and the key underlying technologies that can enable them. Finally, we will give some examples of how Riverstone Networks has worked with technology partners to provide innovative Packet Voice solutions to operators and carriers around the world. The Market for Packet Voice In the late 1990s, there was much talk of voice/data convergence, typically known as IP Telephony or Voice over IP (VoIP). Ambitious predictions were made that the corporate voice and data networks would coalesce into one consolidated network.

Whether this means enabling existing LogicomUSA ® features or building and integrating their own via the RESTful APIs, LogicomUSA ®’s mission is to revolutionize communications by allowing endless possibilities. Private Branch Exchange (PBX) Systems A private branch exchange (PBX) is a telephone exchange or switching system that serves a private organization, performs concentration of central office lines or trunks and provides intercommunication between a large number of telephone stations in the organization. The central office lines provide connections to the public switched telephone network (PSTN) and the concentration aspect of a PBX permits the shared use of these lines between all stations in the organization. Each PBX-connected station, such as a telephone set, a fax machine or a computer modem, is often referred to as an extension and has a designated extension telephone number that may or may not be mapped automatically to the numbering plan of the central office and the telephone number block allocated to the PBX.

  • Voip in an Internet Service Provider Network
    I N T H I S A R T I C L E , I TA K E A L O O K AT how “traditional” Internet Service Providers R O B E R T H A S K I N S deploy Voice over IP (VoIP) [1] in their net- works. VoIP gets a lot of press these days, VoIP in an Internet and there seems to be no end to the hype surrounding it, especially when it comes to service provider service provider networks. This article makes no attempt to cover the basics of network VoIP (see Heison Chak’s excellent column Robert Haskins has been a UNIX system administra- here in ;login:), as this is a huge subject and tor since graduating from the University of Maine with a B.A. in computer science. Robert is employed there are plenty of Web sites available for by Shentel, a fast-growing network services provider based in Edinburg, Virginia. He is lead author of learning more. Slamming Spam: A Guide for System Administrators (Addison-Wesley, 2005). There are at least two ways “traditional” Internet [email protected] service providers could use VoIP in their net- works. The first (and arguably the oldest) method is as a replacement for voice trunks (trunking, either point-to-point or long distance) in their voice networks. This might be done to reduce cost or enable or enhance new voice services. The sec- ond way VoIP is typically deployed is as a replace- ment for a traditional landline phone (for exam- ple, a Vonage [2] or Packet8 [3]) type of service).
