MOBATIME Provides Precise Time Reference in LAN with High Availability

The new NTP time server DTS 4135 by MOBATIME meets all expectations of a state-of-the-art NTP server, such as precision, easy installation and straightforward operation. Additional unique functions make the DTS 4135 the ideal time server concerning reliability and high availability.

The DTS 4135 NTP server does not skip a beat! Necessary corrections of time – e.g. during commissioning or when a leap second is being introduced – are continuously and slowly performed with adjustable speed. This assures continuity for any event logs of NTP clients. Even in redundant operation mode with two DTS 4135, time leaps are prevented if one of the devices fails. This function is made possible by an optical link between the devices. Through this link both DTS 4135 synchronise each other exactly and they negotiate automatically their master-slave status.

The DTS 4135 is always in action! Two independent, integrated mains adapter supply the DTS 4135 dependably. Both power supplies are monitored during operations for a failsafe commutation to the second power supply in the event of an external power outage.

The DTS 4135 is an all-rounder! In addition to the NTP on Ethernet / LAN, the DTS 4135 provides the exact time information by further outgoing ports. These are: audio frequency time codes (IRIG-B, AFNOR, and DCF-FSK), RS 232/485 (configurable, programmable time data strings), DCF77 time code, and configurable impulse and frequency outputs.

The DTS 4135 is a team player! The DTS 4135 integrates itself seamlessly into the distributed time system (DTS) from MOBATIME. The DTS-ready devices are synchronised by NTP and are communicating by the standard protocol SNMP V3. Time servers, master clocks, analog and digital clocks combined to a centrally monitored and controllable system via Ethernet / LAN. The DTS 4135 can be completely operated and monitored via SNMP V3. Therefore, it can be easily integrated into higher-level management software (e.g. HP-OpenView).

The DTS 4136 is even more accurate! Compared to the DTS 4135 the DTS 4136.timeserver offers an increased accuracy due to its oven controlled quartz of higher quality.
