OEM Synchronisation modulesdge

The TeraSync Line of Products

In order to maintain quality operation of telecommunication networks, an accurate timing discipline has to be maintained throughout the network. Network operators as well as the relevant standardization organizations have therefore imposed strict requirements on the timing and synchronization products.

The TeraSync line serves as a vital building block for core telecommunication networks equipment.

The TeraSync family of synchronization modules performs the essential function of clock stabilizing and re-generation in telecommunication core network products. The TeraSync modules perform clockcleaning from the impairments accumulated in the transmission channel, phase jitter and wander etc. TeraSync's modules fully comply with applicable international standards: Telcordia, ITU-T, ETSI.

The international standards allocate a set of requirements to equipment according to their role in the network. TeraSyncws ATiMe modules provide solutions - each matched to the applicable standard set. Bellcore's Stratum 2, Stratum 3 or Stratum 3E, SMC, ITU-Tand ETSI, SEC.

The products available from TeraSync are:
