8.11 Synchronous Ethernet (SyncE)
With SyncE, devices in an Ethernet Network can synchronize their clock to the
frequency used to transmit the network packets. The DTS 4020 supports SyncE
compatible to ITU G.8262/Y1362. It is available on 1 network interface (see Appendix A
Connection diagrams).
The DTS 4020 can be configured to run as a SyncE slave only. It receives the SyncE
information over Layer2 packets (ESMC), with the current quality level information.
Connectors:
Ethernet via 1x RJ45 port
referring to Appendix A Connection diagrams
Transmission mode:
Layer2
Quality Level:
Master Level + 1
8.12 Oscillator
During the start-up, the oscillator has to warm-up. The device waits for the oscillator to
lock/stabilize.
8.13 Logfile Synchronization status
The DTS 4020 provides a logfile under /ram/
date-wd
.log (e.g. /ram/20181114-Wed.log)
about the synchronization status seven days back. The Log interval is 1 minute. The
maximum value of this 1 minute is written to the file.
Example:
Date&Time UTC Offset PTP Offset SyncE Offset Freq. Offset NTP
141118 000000 104 (+) 0 ( ) 0 ( ) 96 (*)
141118 000001 104 (+) 0 ( ) 0 ( ) 96 (*)
141118 000002 104 (+) 0 ( ) 0 ( ) 96 (*)
(*) = active source
Please see chapter 7.6 how to make an ftp connection to the device.
