Frequency Measurements in Compliance with ITU-T G.8262/8262.1


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.

In ITU-T G.8262/8262.1 it defines the EEC with requirements for clock accuracy, holdover performance, noise transfer, noise tolerance and noise generation. 

We can provide test solutions in compliance with ITU-T G.8262/8262.1 recommendations.
