Telecommunication networks are an essential infrastructure for the operation of any power distribution network. The telecommunication services used by power companies can be divided into two classes. First there are the services corresponding to the general communication needs such as telephone services and general data communication services for the operation of the enterprise computer network. Secondly there are special communication needs related to the operation of the physical power distribution network.
Synchronization network is based on SDH or SONET transmission technology. SDH and SONET transmission networks are TDM networks, hence they require synchronization. At the same time the SDH links can be used to transport synchronization.
A PRC generates an accurate and stable reference synchronization signal. Primary Reference Clocks are usually realized with atomic Caesium clocks or with GNSS-receivers, or with a combination of both. The output signal of the PRC drives a so-called SSU or BITS clock. The SSU/BITS acts as a node clock and supplies all telecom equipment of the node or building with adequate synchronization signals. For the transmission of synchronization over long distances, SDH transmission signals are used as carriers.
The physical data rate of the SDH data signal, being driven by the SDH multiplexer's synchronized equipment clock, conveys synchronization which is derived from the PRC. At the receiveing end, an SSU/BITS eliminates synchronization degradations such as jitter and wander and distributes clean synchronization signals to teleom equipment in the node or building.
