Circuit Emulation Over Packet Networks

Overview This paper discusses the evolution of TDM based networks. It briefs the challenges of realizing circuit emulation services over packet networks. This paper also discusses optimal architecture for a device, which can do the packetization and re-assembly process, and providing timing recovery over packet networks. This paper summarizes the Circuit Emulation Services over Packets solutions from Zarlink Semiconductor, which offers comprehensive turnkey solutions, reducing design cycle time.

The Gadget Showdown: The Confrontation in the Next Generation

Packet switching chops data up into little chunks (packets) which can be mixed in with everyone else's packets and sent over a shared network. BT launched its GPRS service to business users in June 2000, and Orange went live with HSCSD (High Speed...

Peter Cochrane's Uncommon Sense: Circuit or packet, clean or dirty?

The most successful attempts see the prescriptive routing and priority of packets so the end-to-end circuit, although based on packets, rapidly resembles its circuit-switched predecessor. The move from circuit- to packet-switched IP networks leaves...

IBM in a sticky situation with chips and glue

Self-assembly would essentially turn circuit mapping into a bottom-up task, with molecules creating patterns as a result of their inherent properties. Chuck Black, a research staff member at IBM research and one of the principal scientists on the...

VoIP primer: How it works - and what the jargon means

The problems of packet loss, delay and jitter are exacerbated when voice traffic intermingles with packets from other applications. Despite long silences, the call is rated for every second the circuit is open.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
