2. QUICKSTART

CONTENT OF THE PACKAGE

Upon delivery, the box should contain the following elements:

► The 19" rack, bearing the mention ”LEDI® NETWORK TDS” ► A C13 power supply cable without locking ► An RJ45 Network cable ► A DVD-ROM that contains software and documentation

☛ Please contact the customers service if one of the items above is

missing

CONNECTING THE SERVER

It may be useful to write down the serial number written on the identication stamp of the

1u 19” rack.

► Connect the synchronization outputs to the devices to be synchronized (see Appen-

dix A – Connections).

► Connect the LEDI® NETWORK TDS V1 server to the network using the network

cable.

NOTE: It is possible to connect the server directly to a computer using a crossed network cable for settings/tests purposes.

ENGLISH

► Connect the power supply cable to the server and switch ON to start it. ► The servers starts. The process may take up to one minute.

NOTE: initialization of the server is slower and may take up to three minutes if there is no network cable connected.

► By default, the server is set up to get its IPv4 and IPv6 addresses from a DHCP

server. If such a server is present on the network, the LEDI® NETWORK TDS V1 is can be accessed directly. Press any arrow key to display the IP Addresses on the server’s LCD front screen.

► The GT Network Manager software (available on the DVD-ROM) can also detect

the server on the network and display the IP addresses.

MDE-LEDI-NETWORK-TDS-4099V1.0

Page 8

3. SETTING UP THE SERVER,

GENERAL INFORMATION

3.1. MANUAL NETWORK CONFIGURATION

By default, the server obtains its IPv4 and IPv6 addresses from a DHCP server.

There are several ways to manually modify IPv4 and IPv6:

► By accessing the web interface, in the « Network » page. (See section 5.2.3. “Page

Network")

► By using the front buttons (See section 4.4.2. “IPv4" ) ► By using the Telnet and SSH consoles (See section 5.2.9. “INTERFACE page")

Additionally, the server will automatically take an IP address in the 169.254.0.0/16 and

fe80::/10 pre-dened scopes. The IP addresses of the LEDI® NETWORK TDS V1 can be

displayed at any time by pressing any of the arrow keys on the front panel.

3.2. OUTPUT CARDS CONFIGURATION

The default conguration for all the output cards is to deliver UTC time and only when the

server is synchronized.

For most of the output boards, it is possible to modify the output time code format, time zone and DST policy.

These settings can be modied in section 5.2.8. "Output Page".

3.3. ALARMS SETTINGS

► The LEDI® NETWORK TDS V1 has an embedded alarm system than can alert the

administrators in case of need.

► The LCD front screen displays the current alarms messages and its backlight blinks to

indicate that at least one alarm condition is happening.

► SNMP traps can be sent to one or several supervision stations.

► The server can send e-mails with details on the situation. ► The server can send Syslog frames to one or two servers. ► Le serveur peut envoyer des trames Syslog à un ou deux serveurs.

These three features can be congured in the « SNMP » and « Alarm » webpages (See

sections 5.2.4. “ALARMS Page" and 5.2.5. “SNMP page").

3.4. NTP PROTOCOL GENERAL INFORMATION

NTP (Network Time Protocol) is a network protocol designed to synchronize a device (the client) with a time reference (the server). The LEDI® NETWORK TDS V1 is a server that can synchronize numerous client devices from a main time source and optionally a client capable of synchronizing on several servers.

In client/server mode, the client queries the server who answers with a time message. The analysis of the transit times allows to determine the time difference between the client and the server, thus deducing the appropriate correction.

Query server date

Receive reply date

client side server side

Network

Return current server date

NTP Exchange

In broadcast mode, the server periodically sends a time output on the network that is received and used by NTP clients. This mode is bandwidth saving but less accurate5 than the Client/ Server mode since the transit times are not compensated.

► The time distribution using the NTP protocol is always done in the UTC time format.

Time zones and DST must be set up on client sides.

► The NTP protocol can be used with MD5 hashes to authenticate the timing information.

The client and the server must use the same secret key and same key index (see section "5.2.6. “NTP” page").

3.5. GENERAL FACTS ABOUT SYNCHRONIZATION

The synchronization is the process during which, a local clock (internal) will be tuned by aligning on a distant clock (the reference).

A local clock works with a reference frequency signal generated by an oscillator. The LEDI® NETWORK TDS V1 uses a thermally compensated oscillator (TCXO).

► The offset is the instantaneous difference between two clocks.

► The drift is the late or advance that is taken by an oscillator as a consequence of its

imperfection. The better the oscillator, the lower the drift.

3.6. OPERATING MODES OF THE LEDI® NETWORK TDS V1

► Not synchronized: no available time input. The server does not have the correct time

and does not deliver time on its outputs.

► Autonomous: the server has been synchronized, but the input is no longer available. It

still has autonomy and keeps distributing time.

► Free Running: The server has been manually forced to run in autonomous mode (time

may have been set by the user). It delivers time on its outputs.

► Synchronized: The server is locked on a synchronization source. It delivers time on its

outputs.

4. FRONT LCD DISPLAY

The front display interface can display up to 4 lines of 20 characters. Six buttons enables the user to navigate in the menus and change some settings.

► A RESET button allows to restart the device except for the GPS input card.

► A POWER button lights up when the device is under power.

► A SYNC button lights up when the device is synchronized. It turns off when the device is

unsynchronized even if it has battery left.

► An ALARM button blinks when the device is not operating properly (e.g. synchronization

or power loss).

4.1. STARTUP

During start-up, the LCD screen displays the message “Init…” until the embedded software starts and displays the loading advancement of the various software modules:

ral alarms are active, each will be displayed successively for several seconds. The

following section describes the meaning of the alarms.

MDE-LEDI-NETWORK-TDS-4099V1.0

Page 13

4.3. ALARM CONDITIONS

Here is a list of the possible alarms and their meaning:

► FREE RUNNING: The server has been forced in autonomous operating mode. No time

input is used for synchronization. Useful for test purposes.

► NO TIME CODE ! The Time inputs of the server are not synchronized. (GPS signal not

received, no NTP server available,...)

► AUTONOMY CRITICAL !: There is no synchronization source, and the server is about

to switch the outputs OFF (3 min autonomy left).

► NEVER SYNC !: The server has been powered for at least 15 minute, and there is still

no valid synchronization source available.

► ETHERNET LINK ERROR: There is a problem with the network cable connection.

► OUTPUT ALARM !: One or several of the output cards are not detected by the main

control card. The status of the output cards can be checked on the Web page in the “Output” tab. This can happen on occasions during initializing and in normal operating. If the problem persists and the corresponding outputs no longer broadcast time codes, please contact Gorgy Timing Customers’ Service.

► SERVER LOCKED: The time outputs have been deactivated by a user.

► SYNC ALARM!: There is no time source available and the server no longer has

battery.

► SECURITY LOCKDOWN!: The conguration interfaces are locked for 5 minutes

following 3 authentication failures.

Sets up the IPv4 address of the LEDI® NETWORK TDS V1 on the network under the following format: xxx.xxx.xxx.xxx, where “xxx” are numbers from 0 to 255.

► Network submask

Sets up the mask of the sub-network to be used. For example, 255.255.255.0 indicates that the scope ranges from 192.168.0.1 to 192.168.0.254.

► Gateway address

The gateway address must be determined for the LEDI® Network TDS V1 to be able

to communicate with elements of the submask. Otherwise leave a blank eld.

► Auto-IP Adress Enable

If the box is checked, an Auto-IP address (i.e. 169.254.x.x/16) is attributed to the server in addition to the manual or DHCP address. This is a default setting.

IPv6 Settings

The current IPv6 parameters are displayed.

► Address from DHCP server

If the box is checked, the LEDI® Network TDS V1 attempts to get an IPv6 address from a DHCP server on startup. Failing to obtain an address this way will result in

the server using its automatically congured IPv6 address.

Unchecking the previous box gives access to the following settings:

► IP Address

Sets up the IPv6 address of the LEDI® Network TDS V1 on the network either in a reduced format (i.e. fc00::0001 in the example above) or in a complete format (i.e. fc00::0000:0000:0000:0000:0000:0000:0001)

► Prex length

Sets up the length of the submask prex. For example, a length of 64 indicates that (fec0:0000:0000:0000: in the example above) denes the network.

► Gateway address

The gateway IPv6 address must be determined for the LEDI® Network TDS V1 to be able to communicate with elements of the submask can be either in a reduced form (i.e. fc00::0008 in the example above) or in a full form (i.e. fc00::0000:0000:0000:0000:0000:0000:0008). Otherwise leave the default value at (0000:0000:0000:0000:0000:0000:0000:0000)

The last part of the page enables the conguration of the following parameters:

► DHCP client identier :

Security options & SNMPv3 credentials

► The LEDI® NETWORK TDS V1 implements a fully compatible SNMPv3 server, with

security options.

► The server can deactivate versions 1 and 2c of the SNMP protocol so that it doesn’t

answer unsecured requests

► To use the security features of the SNMPv3 protocol, specify a username, a

password and an encryption key in the corresponding elds.

► Filling the Password eld automatically enables the password verication on inco-

ming SNMPv3 requests. Filling the Privacy key eld automatically enables encryp-

tion on SNMPv3 exchanges.

► If both elds are lled, the server only answers requests with valid passwords and

privacy keys.

ENGLISH

Enable NTP Server

► If this check box is not checked, the server will not answer to any NTP request.

Reference ID

► This eld shows the current “Reference Identier” used in NTP messages. It is auto-

matically computed depending on the LEDI® NETWORK TDS V1 synchronization status. It can be “DCF” (DCF or GPS synchronization), XNOT if the product is not synchronized, or correspond to the IP address of an NTP server (NTP synchronization).

Current stratum

► The stratum value to be stored in the NTP messages sent to the NTP clients.

MDE-LEDI-NETWORK-TDS-4099V1.0

Page 32

Authentication policy

► Use this eld to choose whether the server will answer to a NTP request, based

on presence of a security MD5 hash. The server can be congured to accept any

request, only secured requests or only unsecured requests.

Serve symmetric active/passive requests

► Checking this box will enable NTP symmetric active/passive requests mode.

If synchronization is lost

► Use this part to determine the behavior of certain elds of the NTP answer message

when synchronization is lost.

► Stratum Level

Stratum level can be modied.

Values can be set from 1 to 16. Select the “Do not modify Leap Indicator” option

to keep the value for the LI eld when synchronization is lost.

► Leap Indicator

The stratum level sent can be modied.

Available values are “3 (0b11)” or “Do not modify leap indicator” to avoid mo-

difying the L1 eld when synchronization is lost.

Broadcast options

The user can ask the LEDI® NETWORK TDS V1 to broadcast time on any address of

the subnetwork by specifying the broadcast address. Also works with a multicast or

unicast address.

☛ This mode allows to synchronize a high number of clocks rapidly.

Enable NTP broadcast on IPv4

► Check this box to set up separate broadcast modes on IPv4.

“Use this broadcast address” elds

► Fill in these elds to enter the IP addresses to be used in broadcast mode.

► Activates the MD5 hash on NTP broadcast messages.

► Select the key in the menu (“Key #1” to “Key #8”) and ll in the corresponding eld

in the “MD5 Keys” area to activate MD5 hashes.

When the autonomy is depleted

► Use this box to choose whether the server keep broadcasting the time in case of

loss of synchronization autonomy.

Section "NTP Client"

If available, the LEDI® NETWORK TDS V1 can be synchronized on up to 5 NTP servers. The NTP software actually uses only one server at a time but can switch to ano-

ther server when there is no or insufcient reply.

ENGLISH

MDE-LEDI-NETWORK-TDS-4099V1.0

Page 34

Polling rate

► This list denes how often the NTP servers will be polled for synchronization.

Number of requests

► This list congures the number of NTP messages to be sent in a train of requests at

the requested polling rate.

Client mode

► The NTP client sends queries to all servers one by one according to their position in

the list. Therefore, the NTP client rst sends a query to the server at the top of the list on startup. If the rst server isn’t available or if no NTP address is provided, the

NTP client sends a query to the second server and so on. The “Client mode” denes the way the NTP client switches from one server to another under normal operating conditions in the case of loss and return of the servers availability (hardware failure, network failure, etc.).

The NTP client only switches servers if the current server is unavailable.

For example:

- The NTP client is synchronized on server 1.

Sync these servers by descending priority

Sync highest available server in the list

- An incident on server 1 makes it unavailable.

- The NTP client therefore synchronizes on server 2.

- Server 1 becomes available again.

- The NTP client remains synchronized on server 2.

Note: in this mode, the number of NTP queries is minimized..

The NTP client attempts to synchronize with the higher server on the list.

For example:

- The NTP client is synchronized on server 1.

- An incident on server 1 makes it unavailable.

- The NTP client therefore synchronizes on server 2.

- The NTP client keeps querying to determine when server 1 becomes available again.

- Server 1 becomes available again.

- The NTP client switches back on server 1 and stops sending queries to server 2.

Note: in this mode, the NTP client keeps querying server(s) located higher on the list than the server it is synchronized with.

Server list

Use these elds to enter NTP servers IPv4 addresses manually.

The “Use gateway” box must be checked if the contacted server is outside the local network. If the index of an MD5 key is provided, the LEDI® NETWORK TDS V1 adds corresponding MD5 hashes to NTP messages when querying the servers.

Statistics on servers availability are also available:

NTP requests sent

Enable autonomous mode

► Checking this box will cause the

LEDI® NETWORK TDS V1 to switch to ‘Free Running” mode where it will run autonomously without a synchronization source. When the box is checked, the following options become available:

► Modify internal time

Checking this box allows to modify and impose the intern time on the system when it is in “Free Running” mode. Intern time and date will be displayed UTC. For example, if local French time is 20:59:00 on 01/02/2010, enter 19:59:00 on 01/02/2010 (one hour earlier since France is UTC+1, DST OFF at this time of the year).

► Stratum

Stratum default value can be imposed in “Free Running” mode.

The stratum default value is 1.

WARNING: Free Running mode should only be used for test purposes. Time may be inaccurate since it may depend on the user’s settings.

POLAR PULSE Polarized impulsion generation is stopped

UTC (Fuseau horaire)

► Under normal operating conditions, the internal time of the device is UTC time. In

order to send local time to the outputs, it is necessary to apply a shift from the UTC

time rst. When a DST correction is implemented, there are two “categories” of time

during the year.

► The rst eld allows to select the sign of the shift (negative “-“ or positive “+”) and

the number of hours (between “00” and “12”).

► The second eld allows to select the minutes of the shift (between “00” and “55”).

For example, the time shift for France is “+01:00”.

DST (Daylight Saving Time)

► Besides UTC, some countries implement a summer/winter time correction. This

correction must be congured to get the actual local time. When a summer/winter

time correction is implemented, there are two different categories of time in the year:

- Summer time (UTC +1 hour)

- Winter time (UTC).

► The existing available policies are detailed in the table below:

DST Begins Ends

Enable Telnet console et Enable SSH console

► NTPServ command invite

The time servers LEDI® NETWORK TDS V1, LEDI® NETWORK ITSv2, LEDI® NETWORK ATS and their NTP output cards as well as the NT0825, NT023 and NT022 modules of the RT4000 feature a command prompt reachable by Telnet (port 9999) and by SSH (port 22). These commands enable to read the servers

status and parameters and to congure them.

Contrary to the Telnet protocol, the SSH protocol includes authentication and data condentiality by cryptography. For more information on the Telnet and SSH protocols see, https://fr.wikipedia.org/wiki/Telnet and https://fr.wikipedia.org/wiki/Secure_Shell.

ENGLISH

► Command prompt access

The command prompt may be opened by several applications, e.g. ssh, Putty and Teraterm. Username and password are required to access the product. These are

either root/gtmt if the root account has not been disabled or the congurable user account identiers (admin/password by default).

It is also possible to connect with a public key. This key and its private key may be generated with the “ssh-keygen” command under Linux or Cygwin in “$HOME/.ssh/ id_rsa.pub” (public key) and “$HOME/.ssh/id_rsa” (private key), then simply add the

le "authorized_keys" in the folder ".ssh" by ftp with the content of id_rsa.pub (only

1 RSA 2048 key is supported by the server).

MDE-LEDI-NETWORK-TDS-4099V1.0

Page 48

To reduce network attacks risks, SSH clients memorize SSH servers. On the rst

connection to a server or during a computer attack by stealing the server identity, a warning message should appear. The choice is then given to the user to access to server or not and to let the SSH client memorize it or not.

► Under Windows

Windows provides the application telnet.exe. To connect to a Gorgy Timing product:

1. Launch “cmd.exe“

2. Enter “telnet <IP> 9999” where <IP> is the IP address. Windows does not feature an application for the SSH protocol. A client software like Putty or Teraterm must therefore be installed. If asked by these applications, the SSH connection parameters are:

- SSH version 2 (ou SSH2)

- Port TCP 22

► Under Linux

1. Launch a terminal

2. Enter ssh -c aes128-cbc -m hmac-md5 <login>@<IP> where: <login> is the administrator username <IP> is the product’s IP address.

3. If the "Agent admitted failure to sign using the key." error appears when authenticating with a key, execute:

eval "$(ssh-agent -s)" && rm ~/.ssh/known_hosts && ssh-add

► Use of the command prompt integrated manual

The manual can be displayed via the “help” and “man” commands. These 2 commands have the same effects:

► If no argument is given,

they display the main page of the manual.

► If a page name is given as

argument, they display the corresponding page of the manual.

There are 2 types of manual pages:

► A command help (one

page per command)

► The list of pages available

for a feature (one page per list)

MDE-LEDI-NETWORK-TDS-4099V1.0

Page 49

► Use of the status commands

The status commands display the state of an element of the time server. Some commands use arguments to specify their functioning. For instance, to know if the NTP input is enabled:

> sync_input ntp en true

► Use of the conguration commands

Most of the conguration commands can be used as status commands to display the current value of a parameter. To change a parameter, the new value must be given in argument at the end of the command. For instance, to disable the NTP input:

sync_input ntp en false

Enable FTP Server

► SIf the feature is enabled, the NTPServ rmware can be updated by uploading an image.

bin le via FTP. To get the latest version of the NTPServ rmware, please contact Gorgy

☛ WARNINGS

More specically, do not interrupt the product’s functioning or reboot it during

the updating process. The device will reboot on its own when required.

Please also make sure to secure the power source(s) before and during the

update.

The product can be used again when the Web pages can be loaded again in the

browser and the Up Time information displayed in the Index page is superior to

1 minute.

During the update, the product will reboot once or twice. The reboots trigger the

reset of the Up Time. Therefore the value displayed in the Index page must be

coherent with that information.

When in doubt, please wait 5 minutes before rebooting the product. That

duration corresponds to the approximate time needed for two secured reboots

of the product following an update.

Ignoring the recommendations above may result in corrupting the network

cards (NTP output cards or main/management Ethernet port). The related

repairs will be billed and are not covered by the warranty

IP 54

► Install away from interference sources such as neon lights, computer screens, etc..

6.1.1. DCF Antenna Réf : 3D6 (four meters cable included)

Receipt frequency: 77.5 kHz

► Install the antenna vertically, then rotate it to get

a ashing of the indicator at the rhythm of one ash per

second and an extinction every minutes (in theory, the antenna has to be positioned facing the direction of the transmitter located near Frankfurt in Germany).

☛ The antenna must be placed outside the building

to optimize the radio signal reception.

☛ If reception conditions are right, the receiver time

setting requires less than 4 minutes.

☛ If the time setting would not be done after fteen minutes, it is

recommended to look for another location..

DCF Antenna characteristics

► Maximum screened two-core cable length: 100m ► Maximum distance from the DCF transmitter (Frankfort – Germany) or TDF trans-

mitter (Allouis – Cher): 200 km (These are maximum values; the actual values may vary with the surrounding land form and atmospheric conditions).

6.1.2. Gps ANTENNA CONVERTER UNIT

Ref: 3G and 3G1 (10m cable included)

► The antena must be placed outside and at the top of the building so as to get the wider

possible reception angle.

☛ Any building or rise superior to 5 degrees above the horizon line may

screen one or several satellites thus reducing the antenna’s performances.

MDE-LEDI-NETWORK-TDS-4099V1.0

Page 57

☛ Although it is not much perturbed by other systems, it is recommended

to avoid installing the antenna directly below a radar.

► Install the antenna vertically. No specic orientation is required.

► The green indicator must be ashing every second to indicate reception of at least

one satellite signal. The ashing duration of the green light varies from 0ms to 200ms

depending on the number of satellite signals received.

► The red indicator ashes every second once the GPS system receives the time indi-

cation. The ashing duration of the red light depends on bits transmitted at the DCF77 format (100ms for a “0” and 200ms for a “1”, no ashing at second 59).

► In some cases (before 2018), the green and red indicators could overlap, thus creating

an “orange” light.

► The GPS code is taken into account if the number of satellites is superior to 2.

► If after reception, the number of satellites remains below 3, the DCF code is stopped

after 20 seconds.

► The setting up of the receptor time must be done between 12 and 15 minutes.

► In the case where the time setup would not be done after half an hour, unplug the

antenna then plug it back in.
