Overview
TimeCesium 4500Cesium Primary Reference SourceDesigned to equip core network offices with Stratum 1 synchronization signals for advanced telecom network services Formerly known as the PRS 45, the TimeCesium® 4500 uses Cesium III beam tube technology to enable telecom network operators to generate superior and highly reliable Stratum 1 synchronization signals.TimeCesium® 4500 is an autonomous atomic Primary Reference Source (PRS) clock that provides total control of network synchronization, enhances overall network performance, flattens synch distribution hierarchy, reduces the frequency errors in SONET/SDH payload and prevents up-stream network clock errors from propagating across the network. TimeCesium provides two accurate and stable DS1 or E1 signals (configurable) using a cesium beam tube resonator to stabilize the output of a quartz crystal oscillator that provides the frequency source for the output generators.
