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 ...

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 ...

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.

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 ...

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 ...

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.

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 ...

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 ...
