The IEEE1588-2008 (PTPv2) compatible PW1008HGP Time and Frequency reference supported by GPS and equipped with internal Rubidium oscillator ensures the precise synchronization across the legacy PDH/SDH infrastructure and over IP/Ethernet networks. The wide variety of the timing output interfaces makes the system ideal for operators migrating their network from TDM to All IP.
