Preface
5T encompasses several technologies, features and capabilities related to time synchronization. From an application perspective, 5T technology allows:
-
Synchronizing servers using PTP
-
Enabling SyncE
-
Offloading TDMA networking
-
Accurately streaming data without drifting
-
Testing and measuring all of the above
