Different from traditional clock group management equipment which has complex building block structure, TimeScale adopts highly integrated design with simple architecture and convenient interface extension. It has multiple time and frequency output ports. Through different flexible configurations, it can establish different timing reference with high precision and reliability.
As per the requirements in packet based networks, ITU-T SG15/Q13 defines the timing and synchronization characteristics in G.8261 recommendations, proposes the concept of Synchronous Ethernet (SyncE), and defines the performance requirements of synchronous Ethernet Equipment Clock (EEC) and Enhanced Synchronous Ethernet Clock in G.8262 and G.8262.1 recommendations.
The accuracy of T-BC plays a key role in the implementation of high-precision time synchronous network in LTE-A , TDD-LTE and 5G. In order to meet the new consistency requirements, three profiles has been published successively including ITU-T G.8273.2, G.8273.2 Amendment1 , G.8273.2 Amendment 2（01/2019）.
