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.

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.

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.

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.

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.

Ensuring that routers, gateways or DSLAMs meet stringent timing specifications usually requires a specialized jitter/wander generator. In this Design Idea, Zarlink applications engineer Slobodan Milijevic describes how to use a standard function generator to more cost-effectively and efficiently measure jitter and wander tolerance.

In a typical telecommunication product, all cards are synchronized to the same clock. The failure of this clock disrupts the data traffic on all cards. To avoid this problem and increase network reliability, telecom products are designed with active and redundant clocks. In this article, Zarlink's Slobodan Milijevic outlines the importance of clock redundancy, presents two methods (parallel and serial) used to implement timing redundancy, and discusses the advantages and disadvantages of both approaches.
