The next generation of telecommunications networks will deliver broadband data and multimedia services to users. The Ethernet interface is becoming the interface of preference for user computers, IP Phones, Digital IP Television and network servers within the network itself. The interface has evolved since 1980 from a simple LAN interface for sharing 10 Mbit/s, though 100 Mbit/s switched LAN interface and to an interface that can also support access lines and transmission tunks at speed from 2 Mbit/s up to 10 Gbit/s. It is inevitable therefore that next generation networks will evolve towards using Gigabit Ethernet for access, trunk and infrastructure connections.
This course will provide a detailed understanding for implementers, designers, managers and infrastructure engineers that need to plan, implement and use the new generation of networks and services.
Delegates who are interested in getting MEF certified should look at our PDN043 Carrier Ethernet Services Explained course.
