Multipurpose time server and grandmaster The DTS 4148.grandmaster sets new standards as a time reference for NTP and PTP clients in medium and large networks (Ethernet/IPV4/IPV6). With its high-precision and intelligent concept for redundant operation, it offers a high degree of reliability and availability. Your benefits using DTS 4148.grandmaster: • Features two completely separated LAN ports: - provides NTP in two different networks - can be synchronized over one LAN port via NTP and synchronize a separated network over the other LAN port - Synchronizes two networks as PTP grandmaster • High degree of system redundancy due to redundant operation via fiberoptic link: - high availability - master-slave operation with automatic switch over in case of an error • Multipurpose device due to the different time code outputs: NTP/PTP, IRIG/AFNOR, serial RS232/RS485, DCF, high accurate pulses Can be used in many different applications due to its multiple functions.

Swiss Time Systems Time precision Best accuracy can be achieved by synchronizing the DTS 4148.grandmas-ter via a connected GPS receiver, and thanks to an intelligent time management. The internal time is adjusted to the time reference (e.g. GPS) in one step or slowly shifted (in adjustable micro steps) to avoid any time leaps (e.g. after a longer loss of the time source). To achieve utmost accuracy, the quartz drift and aging is continuously compensated. Top performance - even for large networks The DTS 4148.grandmaster can process more than 1500 NTP and SNTP requests per second. It can...

Swiss Time Systems DTS 4148.grandmaster - the time source for LAN-based clock and time distribution systems The DTS 4148.grandmaster is a versatile time reference in several respects. On the one hand, it relays the external time signals with high precision and reliability directly to all NTP unicast (IP based) or multicast devices, such as slave clocks with NTP movement (e.g. NBU 190, ...), digital clocks, and digital information displays with NTP and PTP synchronization. On the other hand, it can also synchronize the NMI (Network MOBALine Interface), which can synchronize master clocks and...

Swiss Time Systems DTS 4148.grandmaster - greatest priority for accuracy and reliability Redundant NTP server operation To avoid time deviation between two DTS 4148.grandmasters, they can be linked via a fiber-optic connection by using two GBIC modules. The two timeservers automatically negotiate their state as master or slave. The slave is always synchronized by the master. In case of GPS failure, automatic swap between master and slave state will occur. The parameters for the swap can be configured. The “master” DTS time server always has the better NTP stratum level than the slave....
