TIMING AND SYNCHRONIZATION
Increasing broadband service penetration demands a transport network that delivers significantly lower cost-per-bit than traditional circuit-switched networks, and Ethernet provides the technology baseline for a cost-effective transport technology. Time division multiplexing (TDM) networks such as synchronous optical network/synchronous digital hierarchy (SONET/SDH) and plesiochronous digital hierarchy (PDH) are based on technologies that can natively carry a timing reference at the physical layer. These features are driven by the need to carry TDM timing information to enterprise users over packet networks. Time reference normally acquired by PTP, NTP, SyncE, GPS or Rubidium clock. To ensure the quality of services of the network offer, careful check and test are required to ensure the network have a correct time reference.
