 July 2005 — CESoP Turns The Triple Play
Lightwave 

 

Though it's a rarity on the baseball diamond, service providers are increasingly talking about the "triple play". Zarlink's Peter Meyer looks at the challenges of delivering voice over Ethernet-based networks as part of a bundled package, and how CESoP technology can support carrier-grade service to complete the triple play.


 
 April 2005 — Extending the Reach of TDM Equipment Using CESoP
AnalogZONE 

 

How does a service provider extend the reach of their existing TDM network and services, without deploying more legacy equipment? Zarlink applications engineer Peter Meyer explains how Circuit Emulation Services-over-Packet (CESoP) technology can extending the reach of existing circuit-switched networks and services.


 
 February 2005 — Circuit Emulation in Broadband Access: Converging TDM/Data on the Last Mile
AnalogZONE   

 

While the world is moving "all-IP", enterprise customers have a continued reliance on T1/E1 links and legacy TDM equipment. Zarlink's Tao Lang discusses how Circuit Emulation Services-over-Packet technology and Wi-Fi connections can be used to more economically support business-critical services.


 
 February 2005 — Calling CESoP
New Electronics 

 

While copper and cable connections still dominant when it comes to delivering broadband access, the rollout of fiber to the home (FTTH) networks supporting the "triple play" of services is increasing. Zarlink applications engineer Ullas Kumar explains how CESoP technology can seamlessly carry carrier-grade voice services in packetized form over an all-optical solution.


 
 February 2005 — CESoP and Wi-Fi-The Perfect Marriage
Wireless Design And Development 

 

While the world moves to IP, enterprise customers still rely on T1/E1 services and legacy TDM equipment. Tao Lang discusses how Circuit Emulation Services over Packet technology and Wi-Fi connections can be used to economically support business critical services.


 
 December 2004 — Circuit Emulation Services-over-Packet and Cellular Backhaul
AnalogZone

In this continuing series on CES-over-Packet technology, applications engineer Peter Meyer discusses using CES-over-Packet in a cell site backhaul application. While carriers replace T1/E1 access lines with a packet-based connection, CES-over-Packet technology offers a solution for seamlessly carrying TDM traffic over the new packet network.


 
 October 2004 — Circuit Emulation Services-over-Packet and Standards Adoption
AnalogZone

With the continued need to carry TDM services over new packet-based networks, Zarlink's Bruce Ernhofer and Tim Frost take a close look at the Circuit Emulation Services-over-Packet standards work currently underway with the ITU, IETF, MPLS Forum and the Metro Ethernet Forum.


 
 August 2004 — Making the Packet Connection with TDM-over-IP: A Technology Primer
AnalogZone

When planning a migration from a circuit-based to packet switched network infrastructure, one major hurdle carriers face is how to efficiently transport revenue-generating legacy services. An emerging solution is TDM-over-IP technology. In this article, Zarlink's Bruce Ernhofer outlines some of the economic and competitive issues pushing carriers towards network convergence, and the advantages of TDM-over-IP technology.


 
 August 2004 — Building the Better Backplane: The Marriage of TDMoIP and VoIP
Compact PCI Systems

The tide is turning, and businesses are increasingly ready to migrate circuit-switched voice services to their data networks to realize infrastructure and maintenance savings. In this article, Zarlink's Tao Lang looks at CES (Circuit Emulation Services) as a technology that offers a lower cost, evolutionary approach supporting a wider range of applications in comparison with VoIP.


 
 November 2003 — CESoP is Not VoIP - Making the Voice Connection Over a Packet Network
TMCnet

Voice over an IP-based network was once a novelty, suited only for those willing to endure poor voice quality in exchange for a few dollars in savings. Today, reality has finally caught up to the hype.
