3.3 Introduction
The DTS 4128.timeserver is a NTP Time Server for use in network environments. It
can be synchronized by DCF or GPS (e.g. from GNSS4500) and act as a NTP server
in a network.
In addition, it can be used as a master clock for NTP slave clocks, synchronized via
multicast with NTP and time zone table.
As a “main“ master clock the DTS 4128 can synchronize further master clocks or other
equipment by synthetic DCF.
The DTS 4128 can send e-mails as well as SNMP traps.
Via SNMP configuration and system status can be requested and the DTS 4128 can be
operated.
To maintain a redundant time source, two DTS 4128 can be linked by an optical link.

Device descriptions:
The front plate always has DTS 4128.timeserver printed on it. The precise description
is made on the identification plate on the back.
3.5 DTS distributed time system
The DTS (Distributed Time System) is a system developed by Moser-Baer AG to connect
decentralized master clocks, slave clock lines and time servers. For communication,
standard LAN (Ethernet) is used. The DTS can be centrally operated and monitored.

© MOBATIME 11 / 84 800847.08
3.6 MOBA-NMS - Network Management System
MOBA-NMS is a software used for central management and inquiry of state and alarm
information. It supports DTSdevices aswell as allMOBATime analog anddigital network
clocks and can handle a network with more than 1000 devices. This software provides
extensive functions for the configuration, installation, back-up / recovery etc. especially
for DTS devices.
True to the DTS concept, MOBA-NMS can be installed multiple times in one network.
With different user rights on the device and software level, the configuration abilities of
different users can be set as required.
For DTS devices, all communication is conducted over SNMP V3. The SFTP protocol is
used for broadcasting files.
3.6.1 Overview of the main functions
The main MOBA-NMS functions for DTS devices and network clocks are listed below:
automatic device scan over multicast or IP range
device management using user-defined device groups see chapter „3.6.2
Device management“
intuitive user interface with input check for the device configuration
status / alarm request and display on the device group level
device firmware update for one or several devices (parallel)
support for device commands, e. g. reset, restart etc.
back-up / recovery of DTS devices
transfer of the whole DTS configuration to another device
user management with different access rights
monitor for NTP and time zone packages
editor for time zone files
online help
etc.

© MOBATIME 12 / 84 800847.08
3.6.2 Device management
All MOBATime network devices are displayed in the so-called device view. Here, the
devices can begrouped according to user-defined criteria. For this, the individual devices
can simply be moved to the according groups and sorted using drag and drop. There is
no limit to the number of groups and sub-groups.
Besides the organizational advantages (easier locating, better
overview), a device group has the following advantages:
commands and device updates can be applied to the
whole group (including sub-groups).
Alarms and errors of included devices are displayed on
the group level.
Complete groups can be moved / sorted among
themselves.
The content of the device view can be saved and opened at a
later time. The created structure and breakdown into groups is
preserved.

5 Installation
5.1 Connections
The connections are specified in Appendix "A Connection diagrams".
Only connect the designated devices to the various inputs and outputs.
5.2 Boot procedure of the DTS 4128.timeserver
The normal booting time of the DTS 4128 is approx. 20 sec. with pre-set IP or with
DHCP. The booting procedure of the operating system is displayed on the serial
console. After that, the ’sync’ control lamp is switched off and only switched on again
when time is received from the time source. Without any connection to a DHCP server,
the first start up can take up to 30 seconds. Afterwards, the DHCP option must be set
to "off" in the network settings.
5.3 Firmware
It is recommended to install the current firmware on your device prior to the definite
commissioning. The current firmware can be found under www.mobatime.com 

6 Operation
6.1 General
Operation occurs via a terminal menu or SNMP. SNMP operation is explained in Chapter
“9 SNMP“. Operation with the terminal menu takes place either via Telnet, SSH, or via a
serial terminal. The serial terminal is particularly used for the first configuration. After a
connection has been set up, the login screen is displayed:
To start the menu, dts must be logged in as user. The standard password is dts.
(Changing the password see Chapter “6.5.15 General Settings“).
Only one menu can be open at any time. The first menu started has priority. The menu
is automatically closed after 10 min. without operation, and any possible connection via
Telnet or SSH interrupted.
Backspace:
Backspace must be set to "delete“ with the serial terminal.
Local echo:
Some terminals (serial or Telnet) do not display the characters entered. It is, therefore,
necessary to switch on the "local echo" in the terminal.

6.1.4 Menu structure
The current menu is always displayed in the menu title. The menu options show all
the selectable menu functions. Provided the menu item is not a further menu, the set
parameters are displayed. Error messages (e.g. invalid entries) or additional
information to the selected menu items are displayed in the response line. The input
line shows the current input values or options possible. The status line only appears,
when an information has to be displayed, e.g. "An alarm is active".
All entries must be completed with ENTER (Return) (e.g. also ESC).
The menu window can always be exited with Ctrl-C (incl. termination of the Telnet and
SSH connection).
The desired menu can be selected with the relevant number.
The numbers 98 and 99 are always used identically:
With 98, the settings entered are saved and the menu exited. Depending on the
change, the DTS 4128, or only partial functions, are rebooted.
With 99, all changes to the menu are reversed and the menu exited.
In the menus where data cannot be saved (command 98), the menu is only exited
with 99, but any changes are not saved.
The current menu is updated, without any further entry, with ENTER.

6.2 MOBA-NMS operation
For the configuration of DTS devices via GUI, MOBA-NMS (see chapter „3.6 MOBA-
NMS - Network Management System“) can be used. All configuration possibilities are
subordinated in different configuration pages (called „tabs“). These tabs are connected
to the terminal menu and designated accordingly. Example: The terminal menu
„Configuration Alarms“ can be found in MOBA-NMS under the tab „Alarms“.
Configuration example of a DTS 4128 timeserver:
For further details on the general MOBA-NMS operation, check the integrated online help
(menu „Help Show help“).
Important:
In order for the communication between MOBA-NMS and the DTS
devices to work, SNMP must be activated! Set terminal menu
„Configuration SNMP SNMP Mode“ to „on“. SNMP is active by
default.
