3.3 Device Description in this Manual
This instruction manual is for the Network Time Server NTS.
3.4 Introduction
The Network Time Server NTS is a NTP Time Server for use in network
environments. It can be synchronized by DCF or GPS (e.g. from GPS4500), AFNOR-
A/C, IRIG-B and NTP, and act as a NTP server in a network.
The NTS can provide NTP clocks with NTP and time zone tables via multicast or
unicast.
As the "main“ master clock, the NTS can synchronize other master clocks or other
equipment with DCF or optionally with synchronization impulses.
The NTS can send both e-mails and SNMP traps for alerting purposes.
Using MOBA-NMS and SNMP, the NTS can be fully operated and its configuration and
system status can be requested.

3.6 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.
3.7 MOBA-NMS - Network Management System
MOBA-NMS is a software used for central management and inquiry of state and alarm
information. It supports DTS / NTS 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 / NTS devices, all communication is conducted over SNMP V3. The SFTP
protocol is used for broadcasting files.

© MOBATIME 10 / 84 800984.03
Overview of the main functions 3.7.1
The main MOBA-NMS functions for DTS / NTS 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 / NTS devices
transfer of the whole DTS / NTS 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.
Device management 3.7.2
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 Network Time Server NTS
The normal booting time of the NTS is approx. 60 sec. with pre-set IP or with DHCP.
The end of the booting procedure is signalized by the Init LED. Without connection to a
DHCP server, the first start up can take up to 75 seconds.
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 
Customer Data Product Ressources Time Server.
5.4 First configuration
By default, the LAN interface is configured with the fixed IP address 192.168.46.46, the
net mask 255.255.255.0 and the gateway 192.168.46.1 .
Caution:
The network administrator must be consulted regarding settings on
network devices!
Important: The firewall on the PC may have to be deactivated for the first
configuration.
In case of problems, first check the connection to the NTS using Ping on the PC.
Otherwise, the default configuration must be restored on the NTS according to Chap.
4.3.
First configuration using the default IP 5.4.1
To configure the NTS, a PC must be connected to the NTS either directly or over a
switch (LAN / Ethernet cable RJ45). The PC must be brought into the same address
range (e.g., 192.168.46.2). After that, the connection to NTS can be established by
means of Telnet, SSH or MOBA-NMS.
Configuration IP address Microsoft Windows:
http://windows.microsoft.com/de-ch/windows7/change-tcp-ip-settings
First configuration ARP procedure 5.4.2
If the NTS was never configured before or the default configuration was restored, the
ARP procedure can also be used:
1. Opening of a console: Windows with the command cmd
2. Assign a new IP address to the MAC address of the NTS (marked on the product
label) using the Windows or Linux command arp -s <IP address> <MAC address>
Example for Windows: arp -s 192.168.0.190 00-0c-c6-77-f5-38
Example for Linux: arp -s 192.168.0.190 00:0c:c6:77:f5:38
!

© MOBATIME 14 / 84 800984.03
3. The IP address is temporarily adapted to the NTS by means of the Windows
command ping –l 111 –t <IP address> (l = small L) or the Linux command ping –s
111 <IP address>. The NTS should answer at least two ECHO requests.
Example for Windows: ping -l111 -t 192.168.0.190
Example for Linux: ping -s 111 192.168.0.190
4. Perform the following within 60 seconds after Ping.
Using the Windows or Linux command telnet <IP address>, the Linux command
ssh nts@<IP address> or the application Putty, change the network settings of the
NTS, e.g., telnet 192.168.0.190
5. Delete the ARP entry generated above using arp -d <IP address>
Example for Windows or Linux: arp -d 192.168.0.190
First configuration IPv6 5.4.3
By default, NTS only has one link-local address that can be derived from the MAC
address:
fe80::2[2nd position MAC]:[3rd position MAC]ff:fe[4th position MAC]:[5th position MAC][6th
position MAC]
Example: MAC: 00:0c:c6:77:f5:38
IPV6: fe80::20c:c6ff:fe77:f538
Connection construction with Telnet telnet <IP address>%<interface>:
Example with Windows: telnet fe80::20c:c6ff:fe77:f538%11
Example with Linux: telnet fe80::20c:c6ff:fe77:f538%eth0
In Windows, the interface is called the Scope Zone or Scope ID and can be determined
with the command “netsh interface ipv6 show addresses.“
Putty can also be used with Windows, where the connection can be readily created
using the link-local address (Telnet or SSH):
In Linux, the connection with SSH can also be created by means of ssh nts@<IP
address>%<interface>:
Example: ssh nts@fe80::20c:c6ff:fe77:Ff38%eth0
First configuration with MOBA-NMS 5.4.4
Using MOBA-NMS, unconfigurated NTS can be sought in a local net (same subnet)
and the network settings can be set by means of the current network.
5.5 Basic settings (factory settings)
The basic settings can be found in the table in the attachment “F Parameters“

6 Operation
6.1 General
Operation occurs via MOBA-NMS, 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, nts must be logged in as user. The standard password is nts.
(Changing the password see chapter “6.5.13 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 connection via Telnet
or SSH is interrupted.
Backspace:
Backspace must be set to "delete“ with the serial terminal:
For example, for Hyperterminal under "File Properties Settings - Backspace
sends DEL" must be selected.
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.

6.1.3 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 NTS, 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.
