Resync
Pressing this button resynchronizes the T2 transmission with SNTP and external PPS. This
is required when changing the SNTP server.
Warning: Resyncing may disrupt the T2 signal, which in turn might cause
the modulator to lose sync.
Resyncing causes the T2 Gateway to synchronize it’s timestamp to the highest prioritized SNTP
server, see section 8.4.4. Resyncing might also cause the output TS rate to drop temporarily,
while the T2-Gateway is waiting for the next superframe boundary. When synced the T2-
Timestamp seconds field will be based on the SNTP time, while the subsecond field will be
synchronized to the external PPS.
Note: Please wait a few seconds for the resync to take effect.

Status field stating which SNTP server is used for the initial synchronisation and the status

F for details regarding the Estimated Transmission Time.
