TimeCesium 4500

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.
