What is the full form of CES?

Introduction

Circuit Emulation Service (CES) is a networking technology that allows TDM (Time division Multiplexing) circuits to be transported over packet-based networks such as IP (internet Protocol). It works by emulating the behaviour of traditional TDM circuits over an IP network, allowing enterprises to use their existing TDM-based equipment and infrastructure while taking advantage of the advantages of packet-based networks.

CES basically converts TDM traffic into packets and then transports them over a packet- based total network. This conversion is done using specialised hardware or software called CES devices or CES gateways, which act as an interface between the TDM equipment and the packet-primarily based network.

CES is a cost-effective solution for enterprises that need to migrate from conventional TDM networks to IP-based networks without replacing their existing system. It is typically utilised in industries such as finance, healthcare, and government, in which legacy TDM equipment is widely wide-spread.

Overall, Circuit Emulation service affords a solution for enterprises to modernise their network infrastructure while nonetheless using their existing TDM equipment and infrastructure.

History

The development of Circuit Emulation service (CES) technology dates back to the late 1990s when the need arose to move legacy TDM circuits over packet-based networks including IP.

The preliminary solution to this problem was the usage of TDM over IP (TDMoIP), which allowed TDM circuits to be encapsulated into IP packets and transported over an IP network. However, TDMoIP had limitations, including the incapability to provide accurate clock synchronisation between the TDM equipment and the packet-primarily based network.

In response to these limitations, the CES technology changed into advanced as a greater dependable and efficient solution for transporting TDM circuits over packet-based networks. The CES technology emulates the behaviour of traditional TDM circuits over an IP network, providing accurate clock synchronisation and maintaining the high- quality of service for voice and data traffic.

CES technology has continued to evolve over the years, with enhancements in performance, scalability, and support for newer protocols such as MPLS (Multiprotocol Label Switching). Today, CES technology is widely utilised in various industries where legacy TDM equipment is prevalent, such as finance, healthcare, and government.

Working

Circuit Emulation service (CES) technology works by emulating the conduct of conventional TDM (Time division Multiplexing) circuits over a packet-based total network such as IP (internet Protocol). CES devices or CES gateways act as an interface between the TDM equipment and the packet-based total network and are accountable for changing TDM traffic into packets and transporting them over the packet-based network.

Here's a short overview of how CES works −

• Conversion of TDM traffic − CES devices convert TDM traffic into packets using specialised hardware or software.

• Packetization − TDM communication is transformed and packetized through a protocol such as RTP (real-time transport Protocol) or UDP. (user Datagram Protocol).

• transport − The packetized TDM traffic is then transported over the packet-based network using standard IP routing protocols such as MPLS.Reconstruction − at the receiving end, the packetized TDM traffic is reconstructed back into its original form the usage of CES devices, which also provide accurate clock synchronisation.

CES technology also ensures the quality of service for voice and information visitors by maintaining the desired bandwidth, low latency, and low jitter. Additionally, CES technology supports various types of TDM interfaces, including E1, T1, DS3, and SONET/SDH, making it a versatile solution for enterprises with legacy TDM equipment.
