GNSS PTP Grandmaster Clock & NTP Time Server - DTS 4160.grandmaster


The DTS 4160.grandmaster is a combined time distribution and synchronization device with up to 4 network ports (IPv4/IPv6). It provides a time reference for PTP and NTP clients. With its high-precision and intelligent concept for redundant operation, it offers a high degree of reliability and availability

Time precision
Utmost accuracy is achieved with GNSS synchronization (GPS, GLONASS, Galileo or Beidou). An intelligent time management ensures lasting high accuracy by continuously compensating oscillator drift and aging. The internal time is slowly trimmed to the active time reference (e.g. GPS) to avoid any time leaps (e.g. after a longer loss of the time source)

Top performance for large networks
The high performance DTS 4160.grandmaster can reply to more than 10’000 NTP and SNTP requests per second, which allows for the synchronization of several thousand clients.

PTP Grandmaster
PTP according to IEEE 1588-2008 for the synchronization of highly accurate clients. Usable for telecom (e.g. LTE), energy (e.g. smart grid), automation, transportation etc.

NTP authentication
The DTS 4160 supports NTP authentication for increased security, which allows the clients to verify the source of the received NTP packets 

Safe and convenient operation
Operation over LAN via MOBA-NMS (SNMP), SSH or SNMP protocols is possible. SSH and SNMP (MD5 authentication and DES for encryption) enable a secured connection. Additional connection over RS232 is possible.

Alarm indication
Alarms are reported via SNMP messages, e-mail or by alarm relay. Additionally, the alarm is indicated on the display and on the Alarm LED

4 completely separated LAN ports (3x RJ45, 1x SFP):

  • provides PTP on 3 ports 1- and 2-step master or slave
  • different profiles and domains per port
  • multicast/unicast
  • IPv4/IPv6/Layer 2
  • provides NTP on 4 ports (>10’000 requests/s on all 4 ports combined)

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

  • 1x E1 RJ48 (balanced) or BNC (unbalanced)
  • 2x pulse/frequency/10MHz outputs
  • 1x IRIG-B / AFNOR
  • 2x serial output
  • 1x DCF current loop output

High degree of system redundancy by connecting two DTS 4160 via fiber optic link:

  • high availability
  • master-slave operation with automatic switch over in case of an error

High precision time:

  • Time reception from GPS, GLONASS, Galileo or Beidou
  • GPS disciplined oscillator (GPSDO)
