3.2 Technical Data

See Appendix "I Technical data".

3.3 Device Description in this Manual

This instruction manual is for the master clocks DTS 4801.masterclock and DTS

4802.masterclock. Below both models will be referred to as the DTS 480x.masterclock and only as 4801 or 4802 with regard to the special features of the

individual models.

3.4 Device Description

The DTS 480x.masterclock is a master clock for use in network environments. It can be synchronized both from NTP and also function as an NTP server. In addition, it can import the time from DCF or from GPS (e.g. from GPS 4500).

As a master clock, it can supply a self-adjusting MOBALine clock line (with switch function for clock illumination, switch program and world time function) or alternatively to the MOBALine clock line, a line can also be operated with impulse clocks or DCF active code clocks. The DTS 4802 is equipped with two such lines.

Alternatively it can generate serial telegrams and output them via RS 485 (only DTS

4801) or RS 232. Optional the DTS 4801 is able to drive a monitored RS485 clock line (with switch function for clock illumination) with up to 31 devices.

The DTS 480x can supply NTP clocks with NTP and time zone tables using multicast. As the "Main“ master clock, it can synchronize other master clocks or other equipment

with DCF and monitor with 4 alarm inputs. As an option to DCF, synchronization pulses can also be generated.

The DTS 480x can send both e-mails and SNMP traps for alerting purposes. Using SNMP, configuration and system status can be requested and the DTS 480x

operated. The DTS 480x can be connected as a master clock to a MTC CAN module which can

monitor and synchronize up to 16 master clocks. As part of the DTS system, it functions as a master clock or clock line.

3.6 DTS Distributed Time System

The DTS (Distributed Time System) is a system developed by the company MoserBaer AG to link decentralized main clocks, slave clock lines, and time servers. The LAN (Ethernet) is used as connection. 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 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.

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.

3.7.1 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.

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 Installation Guidelines

Danger! Always consider:

For mains power supply, a plug is located on the rear side of the DTS 4801 / DTS

4802. This power plug separates the device from the power. The DTS 480x must be unplugged from the mains power supply for maintenance or wiring by pulling this plug. The plug supplied may only be connected by a licensed electrician. The effective national installation requirements and guidelines must be followed.

5.2 Connections

The connections are specified in Appendix "A Connection diagrams". Only connect the designated devices to the various inputs and outputs.

5.3 Boot procedure of the DTS 480x.masterclock

The normal booting time of the DTS 480x 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.

5.4 Firmware

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 “4.4.20 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 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.

Localecho:

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 Serial connection

38400 Bauds, 8 data bits, no parity, 1 stop bit. Windows 2000, XP, Vista: HyperTerminal Windows 7: Putty (Download from Internet) Linux: Minicom Switch off Xon/Xoff and hardware handshake. After establishing the serial connection, the menu can be initialized with ENTER.

When rebooting, the boot process will be displayed on the serial console.

Attention:

The serial connection should always be disconnected before switching off the operating PC (exit terminal program or pull out the RS232).

6.1.2 Telnet

6.1.3 SSH

Windows 98, 2000, XP, Vista, Windows 7: e.g. with Putty Linux: Start console and enter “ssh dts@[IP-address]“

Password: dts

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 480x 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 MOBANMS - 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 4801.masterclock:

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.

Important:

Changes of multicast-address, pollinterval and TLL lead to a restart of the NTP server!

Important:

For the operation of a Multicast communication (NTP and Time Zone Server) the configuration of a gateway is required (see chapter 6.5.23 Network). The gateway can be set manually or by using DHCP. If no gateway is available, the own IP can be set as gateway.

Important:

Redundant NTP Multicast time server:

If in the same network two NTP servers should send NTP with the same Multicast IP address (redundancy), then the first time server has to be configured with a small pollinterval (e.g. 2  4 sec.) and the second time server with a large pollinterval (min. 100 x larger, e.g. 9  512 seconds). As long as the first time server is sending NTP Multicast packets, the packets from second time server are ignored. This configuration is needed, to reach a defined situation for the end devices (the DTS 480x.masterclock with the more frequently NTP send rate gets higher priority for time reception).

Time zone table for the NTP slave clock line:

Display of all time zone entries (15) of time zone servers for NTP slave clock lines. Choose a zone number to change selected zone. Time zone selection (see chapter “6.5.28 Time zone selection“) The page can be exited with 99. Changes are first stored or reset on the overlying

e.g. 24 hrs  after DCF/GPS time source failed, stratum counts up from 1 to 16

within 24 hrs

Default value: 12h

For description of time source see chapter “8 Time administration“

6.5.14 NTP server

NTP can run as server or combined as server/client. To run NTP as source (NTP as client), in the menu ’2 Configuration’  '2 Time handling'  ’3 NTP Server / NTP Sources’ at least one server has to be set.

The exact behavior of NTP time sources is described in chapter “8.2 Time take-over, NTP“.

Further 2 multicast or broadcast addresses can be configured:

1.-4. Summary about configured NTP – time sources. Select to configure and display

changes to the menu "ENTRY TIMESOURCE"

5.-6. Summary about configured NTP – broadcast addresses. Select to

configure and display changes to the menu “NTP MULTI- / BROADCAST-

ENTRY“

7. NTP Authentication: Changes to the menu “NTP AUTHENTICATION“ Information about a multicast – address, configured for NTP slave clocks.

Configuration of the individual server/peer address is as follows:

1. Insert time sources (IP-address or Name e.g. “ntp.metas.ch” ENTER without entry of an address will delete value.

2.-3. Configurations of Minpoll and Maxpoll: Inquiry interval 2^poll value in seconds.

0 = automatically

e.g. poll value=2  intervall 2: 2

= 4sec., poll value=5  intervall 5: 25 = 32sec.

Range of poll values (exponent): 1 – 16 To get an exact synchronization it’s better to limit Maxpoll to 6 (64 sec.).

4. Set type of inquiry: server or peer

5. Preferred source: on or off

If possible, one source should always be preferred (even if only one source is defined), except if DCF is active.

6. Authentication key: off, key number, autokey

Important:

All changes lead to a restart of the NTP server!

Important:

Maxpoll should not be selected under 4 (16 sec), as otherwise, internal trimmung may be inaccurate. Maxpoll and Minpoll on automatic can lead to insufficient synchronization accuracy. The specified accuracies were measured with Minpoll = 3 and Maxpoll = 6. The configuration server should be used as far as possible.

Configuration of the Multi- / Broadcast address is as follows:

1. IP address of the destination network (multicast or broadcast). ENTER without entering an address will delete the entry.

2. Interval for sending out the NTP information in seconds. The interval is rounded after the entry to NTP standard, which only permits values of format 2

: 1,2,4,8,16,32,64... maximum 65536 seconds.

3. TTL (time to live) in hops. Only required for multicast. Number of routers over which the multicast packet should be transmitted: for simple networks without a router - enter 1, for 1 router - enter value 2.

4. Authentication key: off, key number, autokey

Important:

All changes lead to a restart of the NTP server!

Configuration of the NTP authentication:

The NTP authentication is described in chapter “8.7 NTP authentication“.

1. Import keys (from/ram directory) The file ntp.keys must first be copied into the directory /ram.

Attention:

The file must be named exactly in this way and written entirely in small letters.

2. Export keys (to /ram directory) The current ntp.keys file is written in the directory /ram.

3. Select the trusted keys separated by spaces

4. Select the request key

5. Select the control key

6. Set the auto key password

7. Execute for auto key commands: gen_iff generate the IFF certificate gen_gq generate the GQ certificate gen_mv generate the MV certificate gen_all generate all (IFF,GQ,MV) certificates gen_client generate the client certificate update_server update the server certificate update_client update the client certificate export_iff export the IFF server certificate to /ram. Parameter password of the client export_gq export the GQ server certificate to /ram. export_mv export the MV server certificate to /ram. import_iff import the IFF server certificate from /ram. import_gq import the GQ server certificate from /ram. import_mv import the MV server certificate from /ram. clear_ram delete the certificates in /ram clear_keys delete the certificates in the NTP key directory

(for backup or copy to another DTS 480x)

Save the current configuration via MOBA-NMS:

1. Select DTS device in the device view.

2. Menu ‘Edit‘  Select ‘Backup configuration…‘.

3. Select the elements that are to be saved. (In case of doubt, select everything)

4. Click button ‘Next >‘.

5. Indicate destination file by clicking the ‘Browse…‘ button.

6. Optionally: enter a free backup comment. E.g. reason for the backup, use, etc. This comment will then be shown during the restoration of the backup.

7. By clicking the ‘Finish‘ button, the backup is created.

8. At the end of the backup, an overview of the process is shown. It shows which elements were saved and which ones are not available or could not be saved.

Save the current configuration via FTP:

1. Connect a FTP client software to the DTS 480x (with Internet Explorer enter:

ftp://dts@[IP address]) (as user dts).

2. Change to the DTS 480x directory /etc.

3. Save the file dts4801.conf (configuration) to the user PC (e.g. copy the file to the

Desktop or to the directory My Documents).

4. Additionally also save possible telegram and program files from the DTS 480x

directory /var/local/dts.

Save the current configuration via USB-Stick:

The whole procedure can be analogously done with an USB stick. The copy procedure to the USB stick can be started on DTS 480x by selecting the menu '3. Maintenance'  ’3. Backup configuration and log to USB’ and press ENTER. All files (including program and telegram files) will be copied into the root directory of the USB stick.

Copy configuration to an other DTS 480x:

In order to copy the entire configuration or elements of it from a DTS device to another, the according assistant in MOBA-NMS can be used. For this, select the source device (from which the configuration shall be transferred) and start the assistant in the menu ‘Edit‘  ‘Transfer configuration…‘. It will lead you through the individual steps.

Without MOBA-NMS, perform the procedure explained in chapter 7.3 resp. 7.5 .

Important:

When copying the configuration from one DTS 480x to an other, the IP address may have to be changed after the download by serial connection

7.10 Copying Telegram or Program files to the DTS 480x.masterclock

Analogously to the previously described procedures telegram and program files can be copied via FTP or USB stick to the DTS 480x.

The copy procedure can be started on the DTS 480x by selecting the menu '3. Maintenance'  ’8. Copy telegram- and program-files' and press ENTER. Afterwards, select again in the menu “6.5.7 Serial telegrams” and reload.

The files are stored in the directory /var/local/dts and can be deleted or copied via FTP.

In addition to the program files (*.prg), *.mbs3 – files (SwitchEditor) can also be copied to the DTS 480x and also be read again later from there.

Special case USB stick:

If the DTS recognizes the insertion of an USB stick, it is shown on the display. By pressing the red button the copy procedure can be released (analogously to the above described procedure). The button has to be pressed until the copy procedure is started.

Management with MOBA-NMS:

With MOBA-NMS, the files do not need to be copied manually via FTP or USB stick, since this is already integrated in the MOBA-NMS operation. At every file selection, the ‘Change…‘ link can be clicked. This opens a file dialog which shows all files and allows new files to be loaded onto the device or existing ones to be deleted.

Example of a program file choice:

Important:

After the file copy procedure, the output of the telegram files and the treatment of the switch programs are re-started (take over of the files).

Important:

The file name is limited to 8 characters before the dot, e.g. IF482Std.tel.

Link for opening the file dialog for editing the file list.

8 Time administration

8.1 Concept of time administration

The internal master clock as well as the real-time clock runs with UTC (Universal Time Coordinated). The synchronisation inputs, the time shown on the display, as well as all outputs are linked via a time zone entry with the master clock time, i.e. all inputs and outputs can be individually allocated to a specific time zone.

8.2 Time take-over, NTP

Generally NTP as per RFC 1305. Maximum 4 sources. Reference clock for DCF with selectable time zone.

Time take-over from DCF:

 Reference clock for the reception from DCF.

At least 3 minutes of reception required before the NTP server is available. Stratum of the time source = 0  Stratum of DTS 480x = 1.

Time take-over from NTP:

 As per NTP RFC 1305 (www.ntp.org)

(see http://support.ntp.org/bin/view/Servers/WebHome for servers on internet)

Time take-over from RTC (internal time of the DTS 480x):

 The NTP server is started with stratum 3, if a DCF source is configured.

As soon as a time source delivers the time, the stratum is set accordingly. If there is no DCF time source configured, the NTP server will only start when it receives the time from another NTP server.

Manual time setting:

 The NTP server will be started with stratum 3 if DCF is configured as time source.

Error cases:

 DCF failure:

Depending on the setting of the “Stratum TO (1-16)”, the stratum will be counted upwards, till it reaches 16. When the startum reaches the value "Stratum limit for synchalarm", the alarm "Failure time source Str" occures (fix delay of 1 min) and the sync LED turns off. When a time source is available again, the stratum will immediately be set according to the time source (stratum time source + 1).

 DCF failure with NTP as backup time source:

Depending on the setting of the “Stratum TO”, the stratum will be counted upwards, till it reaches 16. In case the stratum limit is reached and a NTP server with a better stratum is available, the DTS 480x synchronizes from NTP. When the local time source is available again, the stratum will immediately be set according the time source (stratum time source + 1).

 NTP failure:

The failure of the/all NTP source/s without a defined fix stratum and without DCF. Normally, it takes 8 * the poll intervall of the current source until the peer is recognized as invalid (source can no longer be reached) and NTP loses synchronization. The length of time, with the exception of the poll interval, also depends on the jitter measured, number of sources, length of synchronization and source deviation, and can thus deviate enormously in individual cases.

Exception for time take-over:

After a software update, the first time take over can last distinctly longer (> 8 minutes).

8.3 Fix stratum for local time source

In operation with NTP time sources and the parameter "Local time source = off", the behavior of the NTP server is that of a standard NTP server. When the time sources are no longer available or invalid, the NTP server becomes unsynchronized after a short time as per NTP algorithm.

To provide multicast NTP for slave clock lines, the NTP server has to remain synchronized. An unsynchronized server does not send out any time. The slave clocks in this case will run to the 12 o'clock position.

Therefore, in this case it makes sense to set the Fix stratum value unequal to 0 and if only NTP time sources are in use for the synchronization of the DTS 480x, to set the local time source to local.

Time source(s) Fix stratum = 0 Fix stratum > 0 DCF/GPS with NTP

DCF ok: Stratum DTS 480x always

1, Time always from DCF

DCF nok: If NTP is available Stratum DTS 480x = Stratum NTP source + 1

Else: Stratum is increased as per set stratum timeout value till NTP server is unsynchronized (Stratum DTS 480x = 16)

DCF ok: Stratum DTS 480x always 1, Time always from DCF

DCF nok: If NTP is available Stratum DTS 480x = Stratum NTP source + 1

Else: Stratum is increased as per set stratum timeout value till stratum of time source = Fix stratum  Stratum DTS 480x now keeps fix stratum + 1

DCF/GPS without NTP

DCF ok: Stratum DTS 480x always

1, Time always from DCF

DCF nok: Stratum is increased as per set stratum timeout value till NTP server is unsynchronized (Stratum DTS 480x = 16)

DCF ok: Stratum DTS 480x always 1, Time always from DCF

DCF nok: Stratum is increased as per set stratum timeout value till stratum of time source = Fix stratum  Stratum DTS 480x now keeps fix stratum + 1

Local with NTP

NTP ok: Stratum DTS 480x = current NTP source + 1

NTP nok: Stratum of the local time source is increased as per set stratum timeout value after DTS 480x start  normally the NTP server is unsynchronized quite fast when NTP time source is failed

Attention: no reasonable configuration

NTP ok: Stratum DTS 480x = current NTP source + 1 NTP stratum of NTP time source > Fix stratum

NTP nok: Stratum DTS 480x = fix stratum + 1

Local without NTP

Only for testing purposes for a DTS 480x without any time source which should nevertheless have a NTP time server with a valid time. The stratum of the DTS 480x starts from 0 to unsynchronised as per set stratum timeout value.

Only for testing purposes for a DTS 480x without any time source which should nevertheless have a NTP time server with a valid time. The stratum of the DTS 480x is Fix stratum + 1.

8.4 Time server

 NTP v4 (compatible with v3) as per RFC 1305 (Port 123)

NTP Authentication with MD5 Key / Autokey

 SNTP (UDP), RFC2030 (Port 123)

 TIME (TCP/UDP), RFC 868 (Port 37)

 DAYTIME (TCP/UDP), RFC 867 (Port 13)

8.5 Time accuracy, time-keeping

See Appendix I Technical data.

8.6 Leap second

Manual mode

Notification of the leap second is always issued 1 hour before the period of time set via DCF and NTP*.

*Notification is only transmitted via NTP, if the local source or a DCF source is switched on. If only a NTP source/s is configured, the state of the source will be passed on.

Automatic mode

In automatic mode, the source is checked for 1 hour before the time of the possible leap second (DCF or NTP) for any possible notification. If notification is recognized, it will be passed on via NTP and DCF output and the leap second added.

8.7 NTP Authentication

NTP provides two variants for authentication in version 4:

 NTP symmetric keys (i.e. symmetric keys)  NTP autokeys

NTP authentication assures a correct time source and prevents manipulation of NTP information. NTP data itself is, however, not coded.

8.7.1 NTP symmetric keys

A 32-bit key ID and a cryptographic 64/128-bit hash value of the packet is attached to each NTP IP packet. The following algorithms are used for this purpose:

 Data Encryption Standard (DES)

(partly restricted in North America and no longer integrated into new NTP variants (>V4.2))

 Message Digest (MD5)

The DTS 480x only supports the MD5 procedure.

The receiving NTP service calculates the hash value with an algorithm and compares it with the one contained in the packet. Both NTP services must have the same encryption key and the same corresponding key ID for this purpose. Packets with a wrong key or wrong hash value will not be used for synchronization . The DTS 480x must be correspondingly configured to be able to use NTP authentication (chapter 6.5.14 NTP Server). The NTP service of the other equipment (e.g. server, PC...) must also be configured. In the case of standard NTP, this occurs via the ntp.conf file:

# path for key file keys /etc/ntp/ntp.keys trustedkey 1 2 3 4 5 6# define trusted keys requestkey 4 # key (7) for accessing server variables controlkey 5 # key (6) for accessing server variables

server ntp1.test.org key 2 server ntp2.test.org key 6 server 192.168.23.5 key 3

The description of the ntp.conf file can be accessed via the corresponding man-page, or consulted at http://www.eecis.udel.edu/~mills/ntp/html/authopt.html

The authentication mode is automatically activated when a key is used and the paths for the keys have been correspondingly configured.

trustedkey defines all keys currently permitted requestkey defines the key for the ntpq help tool. controlkey defines the key for the ntpdc help tool.

The keys are located in the ntp.keys file defined with keys. This has the following format:

1 M TestTest 2 M df2ab658 15 M I_see! 498 M NTPv4.98

The key ID is in the first column of the file, the format of the keys in the second defined column, and the key itself in the third. There are four key formats, however, nowadays only the MD5 is still used  M. The letter M is no longer written for new NTP variants (>V4.2) and is only necessary for backwards compatibility. The signs ' ', '#', '\t', '\n' and '\0' are not used in the MD5 ASCII key! Key 0 is reserved for special purposes and should, therefore, not be used here.

ntp.keys: man page for ntp.keys to be noted (check the internet)

8.7.2 NTP Autokey

The validity of the time received to the NTP clients is assured by symmetric keys. For a higher degree of certainty, exchanging the keys used regularly is, however, necessary to obtain protection, e.g. from replay attacks (i.e. attacks in which recorded network traffic is simply played back).

The autokey procedure was introduced as the exchange is very involved in a large network. A combination of group keys and public keys enables all NTP clients to check the validity of the time information which they receive from servers in their own autokey group.

NTP Autokey is relatively complex in its use and studying the functionality is definitely necessary beforehand.

Autokey is descrbied at http://www.cis.udel.edu/~mills/proto.html or on the NTP homepage http://www.ntp.org.

Autokey is currently defined in an IETF draft. http://www.ietf.org/internet-drafts/draft-ietf-ntp-autokey-04.txt

The configuration of Autokey is explained in

http://support.ntp.org/bin/view/Support/ConfiguringAutokey or in http://www.ntp.org/ntpfaq/NTP-s-config-adv.htm#S-CONFIG-ADV-AUTH.

9 SNMP

9.1 General

The SNMP version V2c or V3 for Get, Put and Notification (Trap) is used. A full SNMP agent is implemented on the DTS 480x.masterclock (MIB II, DTS480x). For SNMP V2c, following standard Communities are used:

Read only: romobatime Read/write: rwmobatime Trap: trapmobatime

For SNMP V3, following standard User I Passwords are used: dtsUser1: mobatime dtsUser2: mobatime dtsInfo: mobatime (not changeable, read only)

DtsUser1 and dtsUser2 have full read/write access on all objects. With SNMP V3 rules, access can be reduced. But the access can be restricted with corresponding SNMP V3 rules.

SNMP V3 agent supports user validation (authentication MD5) and encoding (encryption DES).

The following MIB definitions are used: SNMPv2-SMI, SNMPv2-MIB, SNMPv2-CONF, SNMPv2-TC, SNMPv2-TM,

SNMP-FRAMEWORK-MIB, SNMP-MPD-MIB, SNMP-NOTIFICATION-MIB, SNMP-TARGET-MIB, SNMP-USER-BASED-SM-MIB, SNMP-VIEW-BASED-ACM-MIB, RFC1213-MIB, IF-MIB, IP-MIB, IP-FORWARD-MIB, TCP-MIB, UDP-MIB, HOST-RESOURCES-MIB, HOST-RESOURCES-TYPES, DISMAN-EVENT-MIB, NOTIFICATION-LOG-MIB, UCD-SNMP-MIB, NET-SNMP-MIB, NET-SNMP-TC

SNMP V2c,V3: DTS-COMMON (File: DTS-COMMON-MIB.TXT) General DTS definition, always required DTS480x (DTS480x-MIB.TXT)

Device specific DTS definitions

SNMP V1: DTS-COMMON (File: DTS-COMMON-MIBv1.TXT) General DTS definition, always required DTS480x (DTS480x-MIBv1.TXT)

Device specific DTS definitions

The MIB files can be copied from the DTS 480x.masterclock with FTP (for FTP use, see chapter “7.6 FTP Connection“): DTS-MIB: /etc/snmp/mibs/ Standard MIBS: /usr/share/snmp/mibs/

9.2 Device configuration with SNMP

If one or several variables are set with Put in a configuration group, the variable dts480x????ConfigCmd must be set at the end to 1 in the corresponding group. The

values of the entire configuration group are assumed from the DTS with this command (1=accept).

As long as the accept command has not been set, the changed variables can be restored to the old values by setting the

dts480x????ConfigCmd variable to 2

(2=undo, restore). After sending the accept command, a dts480xConfigChanged Notification is sent. The definitions of the available variables can be taken from the MIB files and from the

menu descriptions of this manual.

Example:

Management System DTS

Put dts480xFTPMode=1  Variable is set to 1 internally Put dts480xNetServicesConfigCmd=1  Configuration group is assumed

 Sends dts480xConfigChanged Notification

with the new time

dts480xNetConfigChangedTime

9.3 DTS Subagent SNMP Notification

Protocol: SNMPv2c Notification

Important:

For Notifications to be sent out, SNMP must be switched on. In addition, at least one receiver system must be configured.

9.3.1 Startup [dts480xStartUp]

Sent out when the subagent for the DTS is started. This Notification is always sent out, as soon as SNMP is activated and a destination

address is configured.

9.3.2 Shutdown [dts480xShutdown]

Sent out when the subagent for the DTS is stopped. This Notification is always sent out, as soon as SNMP is activated and a destination

address is configured.

9.3.3 Status changed [dts480xStatusChanged]

Sent out when the subagent detects a status change in the DTS application process. The following variables are monitored for changes:

dts480xSysStatus, dts480xSysTimeSource, dts480xSysStratum, dts480xSysMasterMode

This Notification is always sent out, as soon as SNMP is activated, and a destination address is configured.

The Notification sent out contains the following data:

Field Type Size Description Example

dts480xSysStatus Unsigned Int 4 Bytes

Contains the internal system status

66309

dts480xSysOffset Integer 4 Bytes

Actual time offset of the system [us]

-1523  -1.523ms

dts480xSysTimeSource Byte 1 Bytes Actual time source

dts480xSysStratum Byte 1 Bytes Actual system stratum level

9.3.4 Configuration changed [dts480xConfigChanged]

Sent out when the subagent detects a configuration change in the DTS application processes.

This Notification is always sent out, as soon as SNMP is activated and a destination address is configured.

The Notification sent out contains the following data:

10 Description of the switch function

10.1 General Description

The switch program is composed of 99 week programs and 64 channel programs. The week programs describe the behaviour during one week, independent of date and

channel number. Such a week program can contain numerous lines and each line is composed of time of the day, days of week as well as the switching function to be executed at this moment. The 3 possible switching functions are: ON, OFF, Signal 01 – 99 Seconds.

Now the channel programs assign the week programs to the channels, which are dependent on the date. Such a channel program can contain several lines. Each line is composed of the starting date and the number of the week program to be used.

Up to 1000 lines can be programmed in this way. This is the total sum of the lines in the week and channel programs.

With the PC software "SwitchEditor" the switch programs can be created on a PC and then be downloaded to the DTS 480x via FTP / USB stick. A maximum of 8 characters are allowed for the file name of the switch program file and its extension is PRG, Prg or prg. Additionally the SwitchEditor project file (mbs3) can be stored on the DTS 480x.

Each of the 4 alarm inputs can as control input or switch input be linked to a channel with AND, OR, or exclusive.

If the control input is exclusive, the switch status is transmitted as quickly as possible via MOBALine (0-10sec).

If the control input AND or OR is linked to the switch program, the status of the input is transferred to the next but one minute.

The switch inputs have priority as opposed to the twilight function: i.e. if a control input and the twilight function is linked to the same channel, the twilight function is ignored.

If an alarm input is used as switch input, it must be masked in all alarm masks.

10.3 Behavior at start-up, exchange of switch program file

After starting up the DTS 480x, or after changing the program file, it can take up to 2 min until the switch states to the channel relay are correct.

Important:

The max. number of signal commands is limited to 15 per minute.

In countries where the DST switch date changes annually (e.g. Iran, Israel), the time zone has to be defined manually in the user time zone table (entries 80 – 99).

Legend:

UTC: Universal Time Coordinate, equivalent to GMT DST: Daylight Saving Time DST Change: Daylight Saving Time changeover Standard  DST: Time change from Standard time (Winter time) to Summer time DST  Standard: Time change from Summer time to Standard time (Winter time)

Example:

last Sun. Mar. (02:00) Switch over on the penultimate Sunday in March at 02.00 hours local time.

Important:

The Time Zone Table is usually updated as needed. The current table is available for download under the following address: www.mobatime.com  Customer Area  Customer Support  Support Resources  Time Zone Table. In case your device is equipped with a newer version than shown in this manual, the current time zone settings should be checked.

Modifications / updating the time zone table:

The time zone tables are filed in the /etc/mbsn.tbl (standard table) and /etc/usersn.tbl (user table) files. The user table can be changed with MOBA-NMS or any other Moser-Baer AG software such as, e.g. ETCW. If not changed using MOBA-NMS, it must be updated in accordance with the update instructions (chapter “7.3 Updating applications and configuration via FTP" or 7.5“ Updating applications or configurations via USB)

Important:

The file names mbsn.tbl and usersn.tbl must be written in small letters.
