DTS 4148.grandmaster

The DTS 4148.grandmaster is a time reference for NTP and PTP clients in medium and small networks with up to 2 network ports (IPV4/IPV6). With its high-precision and intelligent concept for redundant operation, it offers a high degree of reliability and availability. DTS4148.grandmaster supports more than 1500 NTP requests per second on both ports.

The DTS 4148 is PTP Grandmaster and NTP Server in order to provide PTP (precision time protocol) and NTP (network time protocol) time distribution services over Ethernet LAN / WAN network. The NTP Server can be configured in server, client or combined client-server mode in order to provide NTP time in unicast or multicast mode.  It further can operate as a NTP time zone server by providing up to 20 time zones into encoded NTPframe for world time clock synchronisation. In addition it provides the following synchronisation outputs: 1x RS232/RS485 configurable time telegram, 1x IRIG-B in both analog and DC level and 1x programmable pulse/frequencies. The DTS 4148.timeserver can be synchronized by a GPS receiver, by IRIG-B time code or by NTP. It can also operate in stand-alone mode thanks an embedded high quality oscillator (OCXO) (in case of time source fail).

  • Supports NTP authentication for increased security, which allows the clients, to verify the source of the received NTP packets.
  • Supports operation over LAN via MOBA-NMS (SNMP), Telnet, SSH or SNMP protocols is possible. 
  • Supports SSH and SNMP (MD5 authentication and DES for encryption) enable a secured connection. 
  • Supports PTP grandmaster (E2E, P2P, two step, unicast, multicast), default and utility profile.
  • Automatic, preprogrammed daylight saving time change.

Technical Features

2 completely separated LAN ports (2x RJ45):

  • Provides PTP on both ports
  • 2-step master (active or passive)
  • Different profiles available
  • Multicast
  • IPv4/IPv6/Layer 2
  • Provides NTP on both ports (>1’500 requests/s both ports combined)

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

  • 1x DCF/pulse/frequency output
  • 1x IRIG-B / AFNOR
  • 1x serial output
  • 1x DCF current loop output

High degree of system redundancy by connecting two DTS 4148 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

Typical applications are Industries, Power Distribution Stations and Power Plants, where high reliability, high precision, no time leaps and permanent availability are required.
