3.3 Device Description in this Manual
This instruction manual is for the time server DTS 4160.grandmaster.
3.4 Introduction
The DTS 4160.timecenter is a primary reference clock (PRC), Grandmaster and
Timeserver for high accurate synchronization of various equipment’s and for the use in
large network environments. It can be synchronized over GNSS, PTP, High Precision
DCF and E1. Equipped with a Rubidium Oscillator it has very high holdover accuracy,
ITU-T G.811 can be achieved.
It is a PTP grandmaster according to IEEE 1588-2008 for the synchronization of PTP
clients.
It is equipped with up to 4 network ports (IPv4/IPv6) for time distribution,
synchronization or configuration.
It can be used as a master clock for NTP slave clocks, synchronizes via NTP unicast or
multicast and with time zone information.
In addition, the DTS 4160 provides one line for E1 / 2.048MHz, IRIG/AFNOR (available
as analogue and digital output), two configurable frequency outputs as well as two
serial interfaces for the output of time telegrams.
To maintain a redundant time source, two DTS 4160 can be connected over an optical
link.
The DTS 4160 can synchronize master clocks or other equipment with DCF.
The DTS 4160 can send both e-mails and SNMP traps for alerting purposes.
Using MOBA-NMS and SNMP, the DTS 4160 can be fully operated and its
configuration and system status can be requested.

3.6 DTS Distributed Time System
DTS (Distributed Time System) is a system developed by Moser-Baer AG to distribute time
information to decentralized master clocks, slave clock lines and time servers or send
synchronization signals to any other equipment. For communication, standard LAN (Ethernet)
is used. The DTS can be centrally operated and monitored.

© MOBATIME 11 / 124 801214.10
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.
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.
Overview of MOBA-NMS functions for DTS devices and network clocks:
•automatic device scan over multicast or IP range
•device management using user-defined device groups
•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
More information are available in MOBA-NMS User-Manual BE-801225.

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 Chassis Ground
In order to guarantee correct operation of the DTS 4160 the chassis must be
connected to an earth ground. The earth ground connection is specified in Appendix “A
Connection diagrams”.
5.3 Boot procedure of the DTS 4160.grandmaster
The normal booting time of the DTS 4210 is approx. 180 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).
The display “starting“ remains until the time of output to the lines.
The duration, depending on the configuration, is 15-45 sec.
5.4 Initial configuration
Per default, all LAN interface for configuration (LAN1 – LAN3) are preconfigured with
DHCP on. After booting in a network with DHCP server, the received IP address can
be displayed.
If no DHCP server is available in the network, initial configuration has to be done via
serial terminal.
5.5 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 Resources Time Server.
5.6 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:
DTS4160 login:
To start the menu, you must be logged in as user dts. The standard password is dts.
(Changing the password

see chapter “6.5.21 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 open connection via
Telnet or SSH is interrupted.
Use e.g. Freeware software Putty as a serial terminal.
6.1.1 Telnet
Windows XP, Vista, Windows 7, 8, 10: e.g. with Putty
Username: dts
Password: dts
Linux: Start console and enter “telnet [IP-address]
6.1.2 SSH
Windows XP, Vista, Windows 7, 8, 10: e.g. with Putty
Username: dts
Password: dts
Linux: Start console and enter “ssh dts@[IP address]“

---------------AN ALARM IS ACTIVE!---------------
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 4160, 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 of a DTS 4160.grandmaster:
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.
