Swiss Time Systems MOBA-NMS (Network Management System) MOBATime's Distributed Time System The multipurpose time server in the new LAN and NTPbased Distributed Time System by MOBATIME DTS 4135.timeserver The DTS 4135.timeserver sets new standards as a time reference for all NTP clients in medium and large networks (LAN Ethernet/IP/UDP). It is highly precise and with its intelligent concept for redundant operation, it offers a high degree of reliability and availability. The DTS 4135.timeserver can either be synchronized from a time signal receiver (DCF 4500, GPS 4500 or IRIG/AFNOR time source), or from another NTP or SNTP time server in the LAN or Internet. The DTS 4135 can synchronize all slave clocks with NTP movements, either with NTP Multicast or NTP Unicast (both with time zone server function). As a multipurpose device the time server is equipped with two independent IRIG/AFNOR outputs, two serial RS 232/RS 485 interfaces with script file programmable telegrams, two DCF or high accurate pulse /frequency outputs (RS 422 and optocoupler) and one additional DCF current loop output. The highest degree of system availability and reliability can be achieved by the master-slave operation of two DTS 4135.timeservers connected via fiber-optic (redundant operation). Alarms are signaled by alarm relay, SNMP messages or e-mails.

Swiss Time Systems Time precision Best accuracy can be achieved by synchronizing the DTS 4135.time-server 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.

Swiss Time Systems DTS 4135 - the time source for LAN-based clock and time distribution systems The DTS 4135.timeserver is a versatile time reference in several respects. On one hand, it relays the external time signals with maximum precision and reliability. It is compatible with 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 Management Interface), which can synchronize master clocks with MOBALine and DCF...

Swiss Time Systems Swiss Time Systems DTS 4135 - highest priority for availability and reliability Redundant NTP server operation To avoid time deviation between two DTS 4135.timeservers, they can be linked via a fiber-optic connection by using two GBIC modules. The two time servers automatically negotiate their state as master or slave. The slave is always synchronized by the master. In case of GPS failure, an automatic swap between master and slave state will occur. The parameters for the swap can be configured. The “master” DTS timeserver always has the better NTP stratum level than the slave....
