Westwood-based Sprint Corp. has contracted with Nortel Networks Corp. of Brampton, Ontario, to convert Sprint's Local Telecommunications Division's digital circuit-switched network to a ...

Despite the growing momentum behind LTE deployments, one of the greatest concerns for established network operators is the legacy of their mature voice networks and their role in the all-IP future.

As the telecom infrastructure evolves from circuit-switched to packet-switched architectures, the Class 5 switch, narrowband digital-loop carrier, and xDSL remote terminal will give way to the ...

In the heady days of the telecom boom, hype led many to believe a full-scale network revolution was underway. Circuit-switched infrastructure was going the way of the dinosaur, the forklifts were ...

For designers who want to migrate to a next-generation, packed-based network, the changes involved may be good, but they aren't easy. Telecommunications design engineers face a number of challenges ...

Despite the industry attention it has received, voice-over-IP (VoIP) is not the only way to send voice across a packet-switched network. In fact, it may not even be the best approach for some ...

If you thought that the digital TV transition, with its billion-dollar coupon program for converter boxes, was a migration nightmare, wait until it's time for the phone system to dump its legacy ...

The architecture, described as ‘packet-controlled circuit-switched double-layer network-on-chip’ provides 11Tbit/s/W communication with every core sending to its neighbour, and 435Gbit/s bandwidth.

Packet switching is a network transmission method that sees data sent in small blocks called packets rather than as a continuous stream. Sending data in this way helps to improve the robustness and ...

Diagnosing the difference between circuit switching and virtual circuits. Q: What is the difference between circuit switching and a virtual circuit? What are the advantages and disadvantages of both ...

Sprint is to change its entire circuit-switched telephone network to packet technology in an attempt to keep up with customer demand for capacity, it announced Tuesday. All eight million of Sprint’s ...

Time-division multiplexing (TDM) over packet technology isn’t a novel concept. It’s already known by a number of different names, such as CESoIP, CESoP, CESoMPLS, TDMoIP, circuit emulation over packet ...
