What is the goal of using circuit emulation service in Carrier Ethernet?

The goal of using circuit emulation service in Carrier Ethernet is to emulate TDM (Time-Division Multiplexing) services over packet networks. This technology enables the transport of TDM-based services, which traditionally rely on dedicated circuits, over more modern packet-switched networks.

Circuit emulation is crucial for service providers that wish to transition from legacy TDM infrastructure to IP-based networks, allowing them to continue servicing customers who rely on TDM protocols without needing significant changes in their hardware or operations. Emulating TDM services provides a seamless way to maintain service continuity while leveraging the cost-efficiency and scalability of packet networks.

This technology effectively encapsulates TDM signals within packet data frames, ensuring that time-sensitive data is delivered in a manner consistent with its original intended performance characteristics.
