The PrimaStratum receives GPS satellite timing signals to control an onboard oscillator providing from one to four T1 or E1 Stratum 1 reference clocks. The PrimaStratum utilizes a mixed-signal phase lock loop GPS driven frequency module to generate extremely accurate 1.544MHz/T1 and/or 2.048MHz/ E1 references clocks that are frequency locked to the Global Stratum 1 source. The Stratum 1 clock is the basis for all telecom voice and data interfaces, required to assure proper synchronization of signals and call quality. The PrimaStratum incorporates this timing signal as a source for timing multiple telecom digital interfaces (T1/E1). These interfaces can be used to synchronize even remote telco equipment to a reliable, standard timing signal.
