RDT - NTP time server which expands network synchronization

In RDT systems an external time source can be used for the NTP time service (e.g. Meinberg satellite receiver) or the RDT System will be synchronized by other external NTP time server.

The RDT system is a perfect solution to expand an existing network structure in which stratum 1 ntp server already exists. The RDT system will be synchronized by NTP and distributes the correct time to its clients via the network interfaces.

Moreover, a RDT system can also operate as a stratum 1 NTP server similar to time servers from our LANTIME M-series. In this case the RDT requires a serial time telegram and a PPS pulse from an external clock (e.g. Meinberg GPS satellite receiver).

As a serial time telegram the Meinberg Standard Time String with CET / CEST or UTC can be used. The Uni-Erlangen-Telegram transmits the offset to UTC as a minute value. The NMEA (National Marine Electronics Association) time telegram can also be used as reference time. Setting of the message type is automatically done by starting the system.

Note: The RDT system does not have an internal hardware clock (Meinberg receiver) and can not provide and distribute the common standard signals (PPS, 10MHz ...), like a LANTIME system with an integrated GPS receiver.
