IEEE-1588 PTP Slave - DTS 4020

IEEE-1588 PTP Slave - DTS 4020

DTS 4020 serves as an interface between the IEEE1588 protocol (multicast slave clock / PTP slave) supplied across a packet network to traditional serial Time-of-Day (ToD), 1PPS, 10MHz and IRIG B signals or NTP client in a PTP / NTP network.


You are about to change your system to PTP but still have legacy systems? Then the DTS 4020 is your solution. It is a PTP slave device according to IEEE-1588, which is designed for such applications. With its multi-purpose time code and frequency outputs (1x Time of Day output 8/ 2x digital pulse / 1x analogue IRIG-B/10MHz output) it enables you to synchronize your legacy devices. Additionally the DTS 4020 features independent LAN Ports for PTP and management, a powerful NTP server on both LAN ports and a redundant power supply.

2 completely separated LAN ports
(2x RJ45):

  • synchronize to PTP on 1 port
    · 1- and 2-step slave
    · different profiles and domains
    · multicast/unicast
    · IPv4/IPv6/Layer 2
  • provide NTP on 2 ports
    (typically <10’000 requests/s on
    both 2 ports combined)

Multi-purpose device due to the different
time code and frequency outputs:

  • 1x Time of Day
  • 2x pulse/frequency/IRIG output
  • 1x IRIG-B/10MHz sinus

Oscillator type:
