Components of a Synchronous Network

 

The figure below is a schematic diagram of an SDH ring structure with various tributaries.

Instead the figure below explains the components of a synchronous network.

Components of a synchronous network

 

SDH should be able to carry different signals. For this reason SDH has different element also called Network Elements.

 

Regenerators

 

This component has the job of regenerating the clock and the relationship of amplitude of incoming signals. They derive their clock signal from incoming data streams. The messages are received by extracting various 64-Kbps channels in the regenerator section overhead (RSOH) and can also be output using these channels.

 

Terminal Multiplexers

 

They are used to combine plesiochronous and synchronous input signals into higher bit rate STM-N signals (Synchronous Transport Module - N layers)

 

Add/drop multiplexers (ADM)

 

They terminate two aggragates signal. SDMs are typically used in a ring configuration. Plesiochronous and lower bit rate synchronous signals can be extracted from or inserted into high-speed SDH bit streams by means of ADMs.

 

Digital Cross-connects (DXC)

 

This NE has the widest range of functions. It allows mapping of PDH tributary signals into VC (Virtual Containers).
