Network Clock for TDM


  • Up to 8 synchronizing inputs

  • Up to 32 outputs in one SSU subrack

  • Up to 128 outputs provided by four Output Extension Units

  • Modular design and scalability

  • Local and centralized supervision and alarm outputs

  • Intelligent tracking algorithm and input signal quality adaptation

  • No phase transient on outputs during input switchover

  • Excellent holdover stability

  • Duplicated power supply

  • Integrated GPS receiver for PRC quality source


Thanks to its modularity PW1008 Synchronization Supply Unit is equally able to provide accurate timing signals for communication equipment of small, medium or large network nodes or telecommunications centers. In SSU mode the equipment is able to handle 8 different and independent incoming timing signals, one of them can be GPS source. The system equipped with internal Rubidium atomic reference makes it suitable for operating as Primary Reference Clock (ITU-T G.811) with excellent holdover performance and providing highly reliable and accurate synchronization outputs for up to 32 telecommunications equipment.
