DTS 4128.timeserver

The DTS 4128.timeserver is a highly precise time reference, specially designed for small & medium size networks (IPV4/IPV6). It supports SNMP V1, V2c, V3 (get, put, notification, trap) with MD5 authentication and DES for encryption.

The high performance DTS 4128.timeserver can reply more than 250 NTP and SNTP requests per second. It can also work as an NTP time reference for a sub-network, being synchronized by a superior NTP-server (client and server at the same time). 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. 

  • The front view of DTS 4128.timeserver shows the LEDs for power supply, alarm, synchronization, and network data traffic, as well as the LAN plug, and the PC connecting plug (RS232 sub-D 9-pole male).
  • DTS 4128.timeserver back view shows DC power supply input, DCF input, DCF output, DC power supply output, alarm relay contact and DTS fiber-optic connection.
  • Effective fault indication by alarm relay, or by e-mail or via SNMP messages.

Technical Features
