3.2 Technical Data
See Appendix "H Technical data“.
3.3 Device Description in this Manual
This instruction manual is for the time server DTS 4148.grandmaster.
3.4 Introduction
The DTS 4148.grandmaster is an 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-B1and
NTP, and act as an NTP server in a network.
This device is a PTP grandmaster according to IEEE 1588-2008 for the
synchronization of PTP clients.
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 4148 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 4148 can synchronize other master clocks or
other equipment with DCF and monitor with 1 alarm input.
The DTS 4148 can send both e-mails and SNMP traps for alerting purposes.
Using MOBA-NMS and SNMP, the DTS 4148 can be fully operated and its
configuration and system status can be requested.
To maintain a redundant time source, two DTS 4148 can be linked by an optical link.
1With IRIG-B synchronization the date must be set manually once or by another time source (GPS).

3.6 DTS Distributed Time System
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.
3.7 MOBA-NMS - Network Management System
MOBA-NMS is software used for central management and inquiry of state and alarm
information. It supports DTS devices as well as all MOBATime analog and digital
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.

© MOBATIME 11 / 108 801053.04
Due 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.
3.7.1 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 „3.7.2 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 / 108 801053.04
3.7.2 Device management
All MOBATime network devices are displayed in the so-called device view. Here, the
devices can be grouped 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 4148.grandmaster
The normal booting time of the DTS 4148 is approx. 60 sec. with pre-set IP or with
DHCP. The booting procedure of the operating system is displayed on the serial
console. After that, the text "starting" appears on the display (during the booting
procedure the display is dark and empty). Without connection to a DHCP server, the
first start up can take up to 75 seconds. After that, the DHCP option must be set to "off"
in the network configuration.
The display “starting“ remains until the time of output to the lines.
The duration, depending on the configuration, is 5-30 sec.
5.3 Initial configuration
Per default, the LAN 1 interface is configured with DHCP on. After booting in a network
with DHCP server, the received IP address can be displayed.
The LAN 2 interface is configured with the following static settings per default:
IP 192.168.1.5, Subnet 255.255.255.0, Gateway 192.168.1.1
If these possibilities do not work out for the initial configuration, the network
configuration can be modified using a USB stick. For this purpose, a text file named
DTS4148NW.conf is created and filled with the corresponding parameters (not all
parameters are required):
IP1:192.168.1.3
SUB1:255.255.255.0
GW1:192.168.1.1
IP2:10.0.0.7
SUB2:255.255.240.0
GW2:10.0.0.1
The insertion of the USB stick is displayed. For taking over the network settings, press
the button until the normal time display reappears.
5.4 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 
Customer Data Product Ressources Time Server.
5.5 Basic settings (factory settings)
The basic settings can be found in the table in Appendix “G Parameters”.

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 or
SSH. 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 “6.5.20 General settings“).
Only one menu can be open at any time. The first menu started has priority. The menu
is automatically closed after 15 min. without operation, and any possible connection via
Telnet or SSH is 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.
6.1.1 Telnet

6.1.2 SSH
Windows XP, 7, 8, 10: e.g. with Putty
Linux: Start console and enter “ssh dts@[IP address]“
6.1.3 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 4148, 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 „3.7 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:
For further details on the general MOBA-NMS operation, check the integrated online
help (menu „Help Show help“).
Important:
To enable the communication between MOBA-NMS and the DTS devices,
SNMP must be activated! Set terminal menu „Configuration
SNMP 
SNMP Mode“ to „on“. SNMP is activ
ated by default.
