Telecom Primary Reference Sources

The highest level of time and frequency accuracy throughout the network

All clocks in a synchronization network must be referenced, or traceable, to a Primary Reference Source. Symmetricom’s GPS Primary Reference Sources (PRSs), also known as "master clocks," provide the highest level of time and/or frequency accuracy for telecom networking as required by international standards. Our wide variety of PRSs are categorized by the source that is used to derive their timing outputs: GPS (Global Positioning System), Cesium (atomic clock), or Packet PRS (IEEE 1588 PTP). Advances in IEEE 1588 Precision Time Protocol, GPS and atomic clock technologies have made providing precision time and frequency within the network more widely available, which assures the highest level of time and frequency accuracy throughout the network.
