RSS circuit-switchedDual Mode Service: Learning From Integrating an IP Multimedia Subsystem Service Into Existing Live Networks
White Paper Several deployable architecture options are possible for building DMS, ranging from legacy, circuit switched network solutions through next-generation network solutions using an IMS architecture. The IP... [31 Jul 2009]
Cheat Sheet: LTE - beyond 3G
Cheat Sheet But while we're on the topic of voice - albeit 'voice carried as data' voice - it's worth stressing LTE networks don't have a separate circuit-switched network for voice, as is the case on existing... [12 Jun 2009]
WiMAX: Technology for Broadband Wireless Access
White Paper These connections are made using leased lines and circuit-switched and packet-switched methods. A Wide Area Network (WAN) is a data network covering a wide geographical area, as big as... [23 Apr 2009]
Generic Access Network, GAN (Former UMA)
White Paper The GAN technology defines a new access network to the mobile core network that can be used to access the existing circuit-switched and packet-switched services. Generic Access Network... [16 Mar 2009]
Testing Ethernet Over SONET/SDH
White Paper The majority of metro and long-haul networks are based on SONET and SDH, as these protocols carry fixed-bandwidth circuit-switched voice very effectively. Data traffic levels continue to increase. As a... [30 Jan 2009]
Detecting Spam in VoIP Networks
White Paper Voice over IP (VoIP) is a key enabling technology for the migration of circuit-switched PSTN architectures to packet-based networks. The problem of spam in VoIP networks has to be solved in real time... [14 Oct 2008]
Analyzing Switched Circuits to Design DC-DC and DC-AC Converters
White Paper The purpose of this paper is to present an alternative analysis of switched circuit to design Square Wave Generators (SWG). A SWG may be designed by using low-cost electronic components, which allows to... [11 Sep 2008]
Cyberpath Power-Over-Ethernet Switching With Avaya IP Office
White Paper Avaya's IP Office fills the gap between yesterday's circuit switched PBXs and Key Systems and the IP-only solutions of tomorrow by meeting the total office communications needs of small-to-medium sized... [11 Sep 2008]
Demonstration of 2.5 Gbps Optical Burst Switched WDM Rings Network
White Paper The designed protocol and accompanying physical architecture allows much flexibility to shift between circuit-oriented and packet-switched traffic scenarios. This paper demonstrates 2.5 Gbps OBS network... [11 Sep 2008]
Feasibility of Flow-Based Optical Provisioning in GEANT
White Paper Historically, telephone calls were injected into circuits at the edge of the network, while data traffic was sent to an IP router towards a packet switched architecture. Since a telephone call is characterized by a set... [11 Sep 2008]
Circuit-Switched "Network Capacity" Under QoS Constraints
White Paper Usually the network-throughput maximization problem for Constant-Bit-Rate (CBR) circuit-switched traffic is posed for a fixed offered load profile. Then choices of routes and of admission control... [11 Sep 2008]
An Energy-Efficient Reconfigurable Circuit-Switched Network-on-Chip
White Paper This paper proposes a new energy-efficient reconfigurable circuit-switched Network-on-Chip. The circuit-switched router has been synthesized and analyzed for its power... [11 Sep 2008]
Circuit/Wavelength Switching and Routing
White Paper This paper gives an overview of the work carried out during the course of the COST-266 action on circuit/wavelength switched network studies. Several subjects are discussed in detail in this paper. A... [11 Sep 2008]
Business Case for Remote Ethernet Testing
White Paper As revenues from traditional circuit-switched voice lines steadily decrease, service providers recognize that Ethernet access and related services represent the future. As a result, they are shifting... [11 Sep 2008]
Statistical Multiplexing in Optical Flow Switching Networks
White Paper Optical flows are optically switched in intermediate nodes and converted into electronic form at termination to treat small nested flows. However, in contrast to the circuit-switching,... [11 Sep 2008]
