DTS 4128 timeserver

Product catalog summary

Overview: The DTS 4128.timeserver is a precise time reference designed for medium-sized networks, supporting NTP clients over LAN Ethernet/IP/UDP. It can synchronize with time signal receivers like DCF 4500 or GPS 4500, or another NTP server within the LAN or internet. It also supports synchronization of slave clocks via NTP or NMI.

Specifications: The server supports over 1500 NTP/SNTP requests per second and can function as both a client and server. It features a 10BaseT/100BaseTX network interface, supports DHCP and static IP configurations, and offers various network services including SNMP and email alerts. The device operates with a DC input of 24 VDC and has dimensions suitable for a 19” rack.

Redundancy and Reliability: Two DTS 4128.timeservers can operate in a master-slave configuration via fiber-optic connection, ensuring high system accuracy and reliability. In case of GPS failure, an automatic swap between master and slave occurs, with configurable parameters.

Time Precision: The server achieves high accuracy by synchronizing with a GPS receiver and compensating for quartz drift and aging. It maintains accuracy within ±100 μs for NTP server synchronization and ±10 μs for DCF output.

Operation and Security: Initial configuration is done via a serial interface, with further operations possible over LAN using Telnet, SSH, or SNMP protocols. Security is enhanced with MD5 authentication and DES encryption.

Applications: The DTS 4128.timeserver is versatile, supporting synchronization of various devices including PCs, clocks, and networked systems. It is designed for medium to large networks, offering flexibility, security, and precise time distribution.

Technical Details: The server supports multiple external time sources, including NTP/SNTP servers and GPS/DCF receivers. It operates within a temperature range of 0 to 60°C and supports up to 80 pre-defined time zones.

Catalog excerpts

Swiss Time Systems DTS Masterclock NTP-based time server The DTS 4128.timeserver is a highly precise time reference for all NTP clients in medium size networks (LAN Ethernet/IP/UDP). It can either be synchronized with a time signal receiver (DCF 4500 or GPS 4500) or with another NTP time server in the LAN or internet. The DTS 4128.timeserver can additionally synchronize all slave clocks with an NTP movement, either direct by NTP input or by means of NMI (Network MOBALine Interface). Other devices, e.g. master clocks, can be controlled via DCF current loop. The high degree of system accuracy and reliability is achieved by the master-slave operation of two DTS 41 28.timeservers connected via fiber-optic cable (redundant operation). In the case of disturbance, an automatic switch over from one device to the other takes place. Alarms are signaled by alarm relay, SNMP messages or

Swiss Time Systems DTS 4128.timeserver - the innovative, precise time reference for networked, multifunctional systems Time precision Best accuracy can be achieved by synchronizing the DTS 4128.timeserver 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 medium size networks...

Swiss Time Systems DTS 4128.timeserver - the time source for LAN-based clock and time distribution systems The DTS 4128.timeserver is a versatile time reference in several respects. On one hand, it relays the external time signals with maximum 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 synchronization. On the other hand, it can also synchronize the NMI (Network MOBALine Interface), which for its part can control master clocks and slave clocks...
