The Need for Synchronization

In the telecommunication system network. If You have many system in the network, there are must be synchronized.


Why do we need synchronization?
For example you have two system A and system B, there are transmitted data and timing to system C.
System C combine signals coming from several different systems. with certain technologies this requires the average signal data rates and possibly the clock phase to be the same. As a consequence, all systems must be synchronized in term of frequency and possibly phase.

The synchronization need for Public Switched Telephone Networks (PSTN), SONET and SDH Transport Networks, also in the 3G/3.5G/Cellular Mobile Telecom Networks
