3.3 Device Description in this Manual
This instruction manual is for the master clocks DTS 4138.timeserver and DTS
4139.timeserver. Below both models (DTS 4138 and DTS 4139) will be referred to as
DTS 4138 with the exception of time-keeping.
3.4 Introduction
The DTS 4138.timeserver is a NTP Time Server for use in network environments. It
can be synchronized by DCF or GPS (e.g. from GPS 4500), AFNOR-A/C, IRIG-B
1
and
NTP, and act as a NTP server in a network.
It can be used as a master clock for NTP slave clocks, synchronized via unicast or
multicast with NTP and time zone table.
It is equipped with 2 LAN interfaces for the operation in two independent networks.
In addition, the DTS 4138 provides an IRIG/AFNOR line (available as analog and
digital (current loop and RS422) output), a serial interface for the output of time tele-
grams as well as an output line for technical pulses (pulse/frequency/DCF).
As the "main“ master clock, the DTS 4138 can synchronize other master clocks or
other equipment with DCF and monitor with 1 alarm input.
The DTS 4138 can send both e-mails and SNMP traps for alerting purposes.
Using MOBA-NMS and SNMP, the DTS 4138 can be fully operated and its
configuration and system status can be requested.
To maintain a redundant time source, two DTS 4138 can be linked by an optical link.

With IRIG-B synchronization the date must be set manually once or by another time source (GPS).
