12.3 TERMINAL (Console)
To connect a serial terminal (according to the device model), use the 9pin RS-232 D-Sub connector in the front panel or the RJ45 connector of the LAN-CPU. Via the serial terminal connection it is possible to configure parameters with a command line interface. You have to use a NULL-MODEM cable (D-Sub) or a
CAB-CONSOLE-RJ45 cable to establish a connection to your PC or Laptop computer.
You can use e.g. the standard Hyperterminal program shipped with your Windows operating system. Configure your terminal program with 38400 Baud, 8 Databits, no parity and 1 Stopbit. The terminal emulation have to set to VT100. After connecting to the timeserver there will be displayed the login message (press RETURN for first connection; default user: root password: timeserver).
12.4 USB Connector
Most LANTIME M-Series products come with a USB interface for connectiong a USB storage device, e.g. a
USB stick. This USB stick can be used for different tasks in combination with the LANTIME:
USB
• Transfer configuration parameters
• between different LANTIMEs
• Keypad locking for secure
• using the keypad of the LCD
• Transfer of log files
• Install Software Updates
• Upload and download secure certificates
• (SSL, SSH) and passwords

12.5 Replacement or Installation of a Hot-pluggable IMS Module
If the system is supplied with an antenna and antenna cable, it is advisable to first mount the antenna in a suitable location (see chapter Antenna Mounting) and lay the antenna cable.
Please use a Torx screwdriver (T8 x 60) for removal and installation of the module.
1.
1.
2.
3.
4.
Follow the safety instructions at the beginning of this manual!
Remove the two marked Torx screws from the module holder plate or the cover plate of the empty slot.
(Only for an already built-in module)
Pull the module carefully out of the holding rail. Note that the module is firmly anchored in the connector block of the housing. You need a certain amount of force to release the module from this link. Once the connection to the connector block of the system’s backplane is loosened, the module can be easily pulled out.
When installing the new IMS module, please ensure that the board is correctly inserted into the two guide rails of the system housing. Non-observance can cause damage to the module and the chassis.
Make sure that the module is securely locked into the connector block before you fasten the two screws.
Now you can put the installed module into operation.

12.5.1 Important Hints for hot-pluggable IMS Modules
The following points should be strictly observed when replacing IMS modules during operation. Not all IMS modules are fully hot-pluggable. Of course, it is not possible to replace a power supply unit of a non-redundant system without first having installed a second power source in operational mode.
The following applies to the individual IMS slots:
PWR: "hot swappable" If you operate your system with only one power supply, a second power supply must be installed before removing/replacing it to keep your system functioning.
I/O, ESI and MRI Slots: "hot swappable".
CLK1, CLK2: "hot swappable" Afer the exchange or the installation of a clock module a rescan of the reference clocks
(Rescan Refclocks) must be executed in the web interface menu "System".
CPU
RSC/SPT not "hot swappable" not "hot swappable"
The central management unit must be disconnected from mains before replacement.
The RSC switching card must be disconnected from the mains before the replacement.

12.6.10 TCR Clock - Time Code Reader and Generator
The IMS - TCR180 serves to decode and generate modulated (AM) and unmodulated (DC Level Shift) IRIG-
A/B/G, AFNOR, C37.118 or IEEE1344 time codes.
AM-codes are transmitted by modulating the amplitude of a sine wave carrier, unmodulated codes by variation of the width of pulses.
As standard the clock module TCR180 is equipped with a OCXO-SQ (Oven Controlled Xtal Oscillator) as master oscillator to provide a high accuracy in holdover mode of ± 1E-8. Optionally an OCXO-MQ or OCXO-
HQ is available for better accuracy.
Receiver:
Automatic gain control within the receive circuit for modulated codes allows decoding of IRIG-A/B/G,
AFNOR, C37.118 or IEEE1344 signals with a carrier amplitude of 600 mV pp to 8 V pp
. The input stage is electrically insulated and has an impedance of either 50 Ω , 600 Ω or 5 k Ω , selectable by a jumper.
DC Level Shift Input insulated by optocoupler with internal series resistance of 220 Ω .

Generator:
The generator of TCR180 is capable of producing time codes in IRIG-A/B/G, AFNOR, C37.118 or IEEE1344 format. The codes are available as modulated (3 V pp
(TTL into 50 Ω and RS-422).
/1 V pp into 50 Ω ) and unmodulated (DC Level Shift) signals
Regarding time code and its offset to UTC, the receiver and the generator can be configured independantly.
Thus TCR180 can be used for code conversion.

12.6.11 RSC Switch Card
Theory of operation
The RSC- Redundant Switch Control card controls the switchover of the reference clock in redundant systems with two receiver units. The RSC is used to switchover the pulse and frequency outputs and the serial interfaces between the available receivers.
The selection of the reference is done by an internal switch-logic of the RSC. The selection of the active system based on the TIME_SYNC signals which are generated by the receivers. The TIME_SYNC signals are indicate the synchronization of the clocks.
To avoid unnecessary changeovers in case of repeatedly occurring free run operations of one system, the master/backup order is changed with each changeover. For example, let’s suppose the current master system looses its synchronization. Then a changeover is performed to a synchronous slave system and thus the former slave system becomes a new Master. No changeover is done if both systems are asynchronous. In this case the current state stays the same.
Important: To ensure an automatic switchover the remote function in a display-menu should be disabled.
"Ref. Time -> Switch Unit": Select Switch Unit -> RSC Cntl -> REMOTE: disable. Otherwise, the system depends on the clock selected by a remote control function and the unit will not switch over to the current active clock.
Display Menu "Remote"
In this operation mode the selection of the reference clock is done by a display menu. A switchover of the reference clock in case of an error does not happen, pulse and frequency outputs and the serial interfaces are always enabled. Deactivation of outputs is possible by a display in the “RSC Cntl” menu.
Display Menu: Switch Unit -> RSC Cntl -> REMOTE : enable

LAN interface alignment with several LNE modules in operation:
Basically, the physical network ports are assigned according to the MAC address order. Thus, the uppermost interface on a LNE module has the lowest and the bottommost interface has the highest MAC address, respectively. Let´s take an example where three LNE modules are inserted in a device. Then the logical order of network interfaces assigned in a webinterface follows the MAC address order of LNE modules, disregarding the
I/O slot order by which the modules are inserted.
In a factory assembling, LNE modules are sorted in an ascending order starting from left to right (see the corresponding figure above). LAN 0 is therefore always the first network interface of the LAN-CPU.

Configurable Port Expander / Backplane Port Expander
The standard output signals like pulses (1PPS, 1PPM and freely programmable pulses) and frequencies (10MHz,
2.048MHz, frequency synthesizer 1kHz-10MHz) are provided by two versatile I/O cards named BPE and CPE.
Both of these two modules have been designed to cover a wide range of interface and signal/protocol requirements. They feature a two-tier architecture with a back-end and front-end.
The back-end is responsible for internally routing the backplane IMS synchronization signals (in case of the
BPE) or for autonomously generating a wide range of different signals by using a microprocessor (on a CPE).
The front-end makes a selection of the signals available on physical connectors.

12.6.19.1 BPE - Backplane Port Expander
Please Note:
In principle, it should be noted that the signals that are provided via a BPE at the various connectors are always generated by the upstream clock and spread via the backplane of the system. In opposite to the CPE, the signals are not generated by the module and therefore the outputs can only be set via the receiver.
The selection and settings of the signals such as frequency, time code or programmable pulse outputs can be done via the web interface menu "Clock" or "Clock Switch Card "(for redundant systems).

12.6.19.3 Configuring an BPE expansion card via the Web Interface
A simple BPE expansion card usually gets its signals directly from the internal backplane of the system. The output signals of the card are pre-configured according to customer requirements.
If an output signal has to be changed, this must be done via the pre-connected receiver - in the menu "Clock →
Switch Card" if you have a redundant system or in the menu "Clock → Receiver" in systems with only a single receiver. The BPE modules have no direct configuration options. This information is also displayed in the "IO

12.6.20.1 IMS-LIU Telecom Output Signals
The board LIU (Line Interface Unit) was designed to convert the GNSS-locked standard frequency of a preconnected Meinberg satellite controlled clock (GPS or GPS/GLONASS/Galileo/BeiDou) into several timing signals that can be used for various synchronization or measurement tasks.
Typical applications are:
• Measurement and test of synchronization quality of Telecom networks
• Calibration and synchronization of laboratory equipment
• Test of synchronization of radio transmitters / base stations (GSM / CDMA / UMTS / DAB / DVB)
Pinbelegung / Pin assignment :

There are two separate signal paths on the board LIU. One is for providing the standard frequencies, the second path is for generation of the "telecom-signals". All output signals have high accuracy and stability because they are derived from the internal receiver’s disciplined standard frequencies generated by the preconnected satellite clock. Depending on the oscillator option of the internal receiver, the accuracies which are described in chapter
can be achieved.

These signals can be devided into two groups: the "clock" outputs and the "framed" outputs, that are provided by a framer and line interface device on the board LIU. All clock signals needed for generation of the ‘telecom outputs’ are derived from a 2048 kHz reference clock, which is generated by a frequency synthesizer on the preconnected GPS- or GLN-clock. This synthesizer is phase locked to the PPS signal and frequency locked to the master oscillator of the clock.
The module LIU is able to generate signals for the American T1- or the European E1-system. The mode of operation can be configured via the web interface of the IMS management module (LAN-CPU).
The clock outputs are standard frequencies of either 1544 kHz (T1) or 2048 kHz (E1). Four unbalanced and four balanced outputs according to ITU-T G703-13 (CCITT recommendation "Physical/electrical characteristics of hierarchical digital interfaces") are available via BNC female and RJ45 connectors.
The "framed" outputs are consisting of data signals known from digital telephony, which are distributed by using a special frame structure (EFS Framing Mode - Extended Superframe). As a synchronization unit, LIU only generates a "framed all ones" signal (data byte 0xFF hex) with a transmission speed of either 1544 kBits
(T1) or 2048 kBit/s (E1). Four outputs according to ANSI T.403 (T1-mode) or ITU-T G703-9 (E1-mode) are available either unbalanced via BNC connectors or balanced via RJ45 connectors. Two different line codes used for error correction are known for the transmission of framed signals. The board LIU generates B8ZS- (in
T1-mode) or HDB3-coded (in E1-mode) output signals by standard.

12.6.21 LNO - 10 MHz Sinus Output Module
The LNO180 is a 10 MHz generator card, which provides sine signals with low phase noise to 4 external outputs.
The card has a microprocessor system, which monitors the output signals and generates status signals for the upper-level management system accordingly.
Function of Operation
The card has a high quality oscillator, which is locked to an external 10 MHz signal. The microprocessor monitors the lock status of the PLL and the warm up phase of the oscillator. It activates the outputs only after the phase is locked. This condition is signalized by all LEDs switched from green to red. In the phase locked state the output levels of the four outputs are monitored and in case of a failure signalized by an associated red LED.

12.6.22 FDM - Frequency Deviation Monitoring
The module FDM180 was designed to calculate and monitor the frequency and its deviation in 50/60Hz power line networks.
A preconnected reference is necessary that provides a serial time string and a PPS (pulse per second). The accuracy of the measurements is derived from these signals. The module calculates the frequency as well as the time, based on the mains frequency. The time deviation (TD) is the difference of this calculated time
(PLT) to the reference time (REF). This time deviation as well as the frequency itself is sent out via serial interface or is beeing converted to an analog voltage output provided by a DAC.

12.6.23 REL1000: Error Relay Module
The REL1000 error relay module can be switched by various operating states (e.g.: Clock Not Sync). If the internal hardware clock is running synchronous to the source, the relay is switched to NO (Normaly Open) mode. In case of an error, the relay switches to NC (Normaly Closed) mode.
Depending on the hardware configuration of the IMS system, i.e. redundant with RSC module and two integrated reference clocks or with SPT module and only one reference clock, different relay states can be switched.
In redundant operation, the two clocks and the changeover unit are monitored as standard (CLK1 - relay
A, CLK2 - relay B, RSC - relay C). This jumper setting is supplied per default in redundant systems.
Possible configurations of Error Output:
Relay A: Clock 1 / Notification Events → Relays
Relay B:
Relay C:
Clock 2 / PPS
RSC / 10 MHz / Notification Events → Relay
In redundant mode, the jumpers on the REL1000 are set as shown below:

12.6.23.1 Configuration of the REL1000 via the Web Interface
The relays A + C of the REL1000 module can be switched via notifications events. If the jumpers and hardware configuration are set accordingly, a checkbox can be activated in the web interface menu "Notification → Notification Events" for various events, so that the selected relay is switched to error mode on this event.
Selectable events are "NTP not Sync" or "Clock not Sync" for example.
In this figure there are no selection options - the relays are switched in redundant operation via the reference clocks and the RSC switch unit.
This figure shows the menu in a non-redundant system. Relay C can be controlled via notification events.
