Operating Instructions Safety Instructions

RF/160 OI 1-1

1 Safety Instructions1.1 Application

These microwave radio systems are designed to meet environment class 3.2 as defined in ETS 300 019.This class specifies system applications in partly temperature-controlled rooms (-5 °C to +45 °C, max.95% relative humidity). The systems may be used only under the conditions and for the purpose for whichthey have been developed. For more detailed information, please refer to the “Technical characteristics“indicated in the Operator Manual.Installation and Service works may be executed only by technically trained and experienced staff knowingthe hazards that can occur and the measures to be taken for minimizing any danger for themselves andthird parties.� Please note all warnings and instructions contained in this Manual.� Only service staff should be granted access to the active system.� Do not use any installation materials (screws, nuts etc.) different from those supplied with the

equipment or recommended by the manufacturer.� Use appropriate safety devices while you are working on top of or near the mast.� The system may be installed and operated only in locations with restricted access.

1.2 Protection class

The DRS 155/...-64/128 MLQAM E system meets protection class IEC IP 20.

1.3 Operating voltage

The Tx, Rx, MU PS and OHAU PS modules of the microwave radio system can be operated in thevoltage range from 19 V to 75 V DC. The voltage input is floating, i.e. either the positive pole (standard)or the negative pole can be grounded. The standard cables used for setting up the connection to thepower box (distributor) are dimensioned for the voltage ranges of 48 V and 60 V.Thicker cable cross-sections are required for 24 V.

Before switching on the power supply, please check that the operating voltage and supply voltageare identical and that the polarity is correct (Fig. 1-1).

Fig. 1-1: DC port Sub-D , 3-pin, male

Ensure that the power supply has been switched off before you plug in or pull out any moduleconnecting cables. This applies to both control and operating voltage cables of the Modem Unit,OHAU as well as Tx and Rx modules.If the RPSI module is pulled out or plugged in live, transmission faults may occur in the protection channel.Ensure that the following conditions are fullfilled:

1. No operating channel must be protection-switched.2. The protection switching function must have been enabled or3. the links between the corresponding RPSI and RPS-C modules must have been cut.

The following modules may be inserted in or extracted from the subrack only with the power supplyswitched off:

Modulator = Mod/MD (in Modem Unit)Demodulator = Demod/DM (in Modem Unit)SOH Access (in OHAU)Power Supply = PS (in OHAU & Modem Unit)

Safety Instructions Operating Instructions

RF/160 OI1-2

For safety reasons, we always recommend to switch off the corresponding power supply unit at thefuse panel before you extract or insert a module!The automatic circuit breakers must be located in the feeder line of the ungrounded pole.With the standard fuse sockets of Power Box II, the system may be operated only usingbatteries with the positive pole grounded.

1.4 Rack installation

The system racks (ETSI or 19“) must be protected from tipping over by screwing the clips (Fig. 1-2) to thewall or ceiling using appropriate securing material. For more detailed information, please refer to theInstallation Manual.

Fig. 1-2: Rack installation

1.5 Rack grounding

The racks must be grounded at the protective grounding point located in the top section of the rear rackupright (Fig. 1-3) using a protective conductor (16 mm²). The individual modules are grounded via themetal rails of the subracks and rack. For further instructions, please refer to the Installation Manual.

Fig. 1-3: Protective grounding point

RF/160 OI 1-3

1.6 ESD protection

The system rack is equipped with two grounding points (Fig. 1-4) with a 10 mm snap fastener forconnecting a grounding bracelet. By grounding the wrist, it is possible to avoid electrostatic dischargesthat could destroy sensitive electronic components when touching the modules.

RF/160 OI1-4

1.7 Laser safety

The Modem Unit can be optionally equipped with two optical modules (SPI) (Fig. 1-6).

The laser used meets LASER CLASS 1 (Fig. 1-5) as defined by EN 60825-1.

Fig. 1-5: Laser warning label

The laser complies with ITU-T G.957 and features the following characteristics:

S-1.1 L-1.1Wavelength 1310 nm 1310 nmOutput power -8...-15 dBm 0...-5 dBmPulse duration 6.43 ns 6.43 nsBeam divergence approx. 23° approx. 23°

The module is automatically deactivated by an ALS (Automatic Laser Shutdown) circuit as soon as theoptical input signal fails (e.g. in case of a cable break). In case of a loss of signal of the SPI, the laser isalternately activated for 2 seconds and deactivated for 70 seconds. Besides this automatic testing routine,it is also possible to switch on the laser manually for 2 seconds or 90 seconds. After expiry of thecorresponding period, the system returns to the previous testing cycle.

Maintenance and repair works must be executed by qualified service personnel.

The laser source emits invisible laser radiation. Laser beams may lead to irreparable eye injuries.Never look into the laser source or onto the connector surface of FO cables connected, not even withoptical instruments.

� CAUTION!Use of controls or adjustments or performance of procedures other than those specified herein mayresult in hazardous radiation exposure.

RF/160 OI1-6

1.8 RF interfaces

When opening the RF interfaces (waveguides or semi-rigid cables) while the transmitters are active,microwave radiation is emitted which may lead to health hazards.In addition, this can lead to RF interferences in neighbouring units.Do not look into open waveguide connections and do not stand in front of transmit antennas.

Fig. 1-7: RF interfaces

The SMA connectors of the coaxial cables between the Tx modules, Rx modules and channelbranching networks may only be tightened with a torque of approx. 60 Ncm. A higher torque wouldslacken the SMA connectors at the RF filters when opening the joint. This would lead to a change of the filter characteristic.

Warning : Do not open waveguide joints withoutswitching off the transmitter. Stray RF poweris harmful to the body (particulary to the eyes)and can also cause RF interference.

Warnung : Nicht die Hohlleiterverbindungen öffnen bevor die Sender ausgeschaltet sind. Mikrowellenstrahlung kann gesundheitsschädlich sein, besonders für die Augen.Ebenso können Gerätestörungen verursacht werden.

General

� XPIC activeThis option is activated in XPIC operation. In the Slave mode, the synchronization input of theoscillator is monitored by the Rx Slave.

Rx oscillator

MasterIn XPIC operation, the LO (DRVCO) of the receiver operates as clock source (Master) forsynchronizing the cross-polarly connected receiver.

�In normal operation (without XPIC), the receiver operates as Master.

This setting is used only to enable or disable the XPIC synchronization alarm of the oscillatormodule.

IF amplifier

Operating mode

NormalDue to the low control time constant, the amplifier can react to rapid level fluctuations.

�Setting in normal operation: Normal

SweepThe control time constant of the IF amplifier is increased. Thus, rapid level fluctuations are not compensated during a sweep measurement in order not to falsify the test result.

Key word 4-8: Activating the Rx ATPC

ATPC

� Manual TX power control (MTPC)The ATPC is deactivated. The power of the far-end transmitter can be adjusted manually in the "Manual Tx level" box.

�Setting in normal operation: inactive

� Overdrive mode permitted Tx power control depends on the BER of the receive signal. At a BER of approx. 1E-6, the reachable maximum Tx power is increased by 1.5 dB in the overdrive mode (this must also be enabled in the far-end transmitter). In this mode, the backoff factor required to achieve the specified residual bit error ratio (RBER) is reduced. The resulting degradation, however, is neglible compared with the BER of 1E-6 occurring on the radio hop. This permits the radio hop link to be maintained even in case of deep fading events. Activation starts at PRx < -68 dBm for 64 MLQAM and at PRx < -66 dBm for 128 MLQAM. The overdrive mode is only active, if the ATPC function has been enabled.

� Compensation ONThe mode required for executing and testing the length compensation function is activated.The signals available at the combiner inputs are shifted with respect to each other using aprogrammable phase shifter. Delay time differences between the main and diversity signalpaths caused by different waveguide lengths lead to notches moving through the outputspectrum. Using an IF spectrum analyzer connected to the combiner output, the delay timedifference between the main and diversity signal paths can be determined and the lengthcompensation can be performed and tested.

� Auto-runThe phase shifter is periodically triggered with the adjustable frequency.A notch occurring is moving through the spectrum.

This option does not have to be acknowledged after selection!

� Single stepThe phase of the phase shifter is shifted by approx. 3 degrees per step. The notch moves through the IF spectrum in single steps.

Key word 4-18: Adjusting the DM group delay equalizer

Group delay equalizer (only for 64 MLQAM)

The group delay equalizer in the demodulator compensates distortions caused by the connection of RFfilters with a direct adjacent channel spacing. Direct adjacent channel filters are the channels routed at aspacing of +/- 40 MHz to the channel considered.

An important parameter is the number of direct adjacent channel filters "passed" above and below thechannel to be adjusted in the Tx and Rx branching network.

The mutual influence between two direct adjacent channels in a diplexer is half as high as with the samechannel combination with individual filters or combinations of individual filters and diplexers.Two direct adjacent channels arranged within a diplexer identify "one complete passage" only after theTx-side and Rx-side diplexer have been passed. Diplexers are always arranged in identical pairs both onthe Tx and Rx side.


RF/160 OI 4-25

Example for determining the adjacent channel filters passed

Arrangement with a combination of individual filters and diplexer filters

(Schematic arrangement for demonstration purposes only; selection of appropriate attenuation values inthe factory => Reverse order of channel diplexers on the Tx and Rx side).

- Channel 2a passes direct adjacent channel filter 1a (1x) (pair of diplexers!)(corresponds to line 6 of the table below).




- Channel 3a passes direct adjacent channel filters 4a (2x) and 2a (2x)(corresponds to line 3 of the table below).

- Since the compensation takes place at IF level, a distinction of different cases is necessary depending onthe position of the RF oscillator with respect to the RF channel (downstream combination in reverse oridentical position).

RF/160 OI4-32

� Enable QA2 criterion- Activation of the QA2 criterion for protection switching purposes.- The QA2 criterion is a threshold activated in case of a slight degradation of the transmission

quality of the channel. After synchronization of the operating and protection channel on theTx-side a switchover is carried out.


� Enable LWI criterion1

- Activation of the LWI criterion for protection switching purposes.- The LWI criterion is the sum of early warning pulses (correction pulses) of the DM FEC of

each DM included in a transmission link covering several radio hops. After synchronization ofthe operating and protection channel on the Tx-side a switchover is carried out.

Q0 threshold valueQ1 threshold valueQ2 threshold value- Adjustable Bit Error Ratio (BER) for the Qx thresholds, with Q0 > Q1 > Q2. Values between

10-12 and 10-3 are adjustable. The respective threshold is taken into consideration only if theassociated QA criterion has been enabled.

� Recommanded setting: 64 QAM 128 QAMQ2=10-11 Q2=10-12

Alarm threshold value- Number of protection switchovers to enable the "number of protection switchovers exceeded

threshold" alarm.Key word 4-21: Switching thresholds

Operating channel� Automatic- When this option has been selected, the channel will be protection-switched automatically in

case of a fault or degradation of the transmission quality. The “Setting” box displays thechannel automatically selected (OP, PR1 or PR2).If this option has not been selected (check mark), user-controlled switchover is possible viathe “Setting” box.

� Frequency diversity (read-only access)- The signal of the operating channel is transmitted parallelly via a second RF channel

(protection/standby channel). An internally controlled switch selects the better one of the twosignals on the receive side.Frequency diversity is activated only in the “1+1 line protection without OT” systemconfiguration (with a DPU/RPS STM-1 A002 module)!

SettingWith the “Automatic on” option selected, the channel (OP, PR1 or PR2) currently used will bedisplayed:- OP

No protection switching active.- PR1

The operating channel has been protection-switched and is being protected bystandby channel PR1.

- PR2The operating channel has been protection-switched and is being protected bystandby channel PR2.

1 In case of 128 QAM systems with OT option, it is recommended not to enable the LWI criterion in

order to avoid unnecessary interruptions of the channel used for transmitting occasional traffic. Thisapplies to DPU software versions up to V106/221100.


RF/160 OI 4-33

With the “Automatic off” option selected, a user-controlled switchover is possible. In this case,the system behaviour depends on the “Precedence” option.

The “Precedence” option inactive leads to a manual switchover request:- OP

An existing protection switching function shall be deactived, if possible.- PR1

The operating channel shall be protected by standby channel PR1, if possible.- PR2

The operating channel shall be protected by standby channel PR2, if possible.- PR1 or PR2

The operating channel shall be protected by standby channel PR1 or PR2, if possible.The appropriate selection is made by the system on an internal basis. No display.

The “Precedence” option active leads to a forced switchover request:- OP

An existing protection switching function is deactivated. The operating channel is neverprotection-switched.

- PR1The operating channel is continuously protected by standby channel PR1, provided that thelatter is not used for occasional traffic (OT) on a permanent basis.

- PR2The operating channel is continuously protected by standby channel PR2, provided that thelatter is not used for occasional traffic (OT) on a permanent basis.

- PR1 or PR2The operating channel is continuously protected by standby channel PR1 or PR2.The appropriate selection is made by the system. Only command, no display.

� PrecedenceIn case of an automatic switchover (“Automatic“ active), the following applies:- This option increases the priority of the operating channel for protection switching

(see “Priority” box). Priority low = 15, Priority high = 0.- The activation of the “Precedence” option causes the value in the “Priority” box to be

reduced by 8 (� higher channel priority) provided that the value displayed was higher than 7.- The deactivation of the “Precedence” option causes the value in the “Priority” box to be

increased by 8 (� lower channel priority) provided that the value displayed was lower than 8.

In case of a user-controlled switchover (“Automatic” not active), the following applies:- If the “Precedence” option is active, a switchover command is always executed, independent

of the status of the selected channel (� forced switchover).- If the “Precedence” option is not active, the system permits a switchover only if the selected

channel is not faulty. After switchover, the system will return to the operating channelautomatically as soon as a fault is detected in the channel selected by the user (� manualswitchover request).

Priority- Adjustable channel priority. High = 0. Low = 15.

RF/160 OI4-34

Protection channel

Occasional traffic- The system can transmit low-priority traffic via an additional SPI module in the protection

channel. In case of failures, the OP channel is protected by the PR channel and occasionaltraffic is interrupted.

none- No occasional traffic.- If none of the OP channels is faulty in the 'n+m line protection mode' of an 1+1 configuration,

the data of operating channel OP1 are parallelly transmitted in PR1 (active frequencydiversity).

loose- The transmission of low-priority data is interrupted as soon as an OP channel is detected to

be faulty.

Protection types for service channels

Only in microwave radio 1+1 equipment protection and 1+1 line protection configurations without OT (withone DPU/RPS STM-1), service channels are also protected by the radio protection configuration.Depending on the type of protection switching configuration, service channels can be protected byconfiguring the associated modules as defined in Table 2 below. This service channel protectionswitching process is not hitless.

Meaning of the different configuration options:� 1+0: The service channel is not protected.� 1+1: The service channel is protected.� TX1+0: The service channel is not protected on the Tx side and protected on the Rx side.� RX1+0: The service channel is not protected on the Rx side and protected on the Tx side.� 2+0: SC-OP and SC-PR transmit two independent unprotected service channel signals.

The protection channel (PR) for the STM-1 signal is not automatically used as protection channel forservice channels. In n+m (n>1) configurations, the service channels are transmitted in OP1 (SC-OP)and OP2 (SC-PR).

Layer-3 addresses

The Layer-3 address (OSI-L3 address) is required for setting up a transmission link between the SOA andNE, for the remote logon from one NE to another and for OSI routing. The OSI-L3 address is also referredto as NSAP (Network Service Access Point).In most cases of application, the OSI-L3 address of the NE is generated automatically from the NEmanufacturing no. (automatic mode). In this case, further settings in the "Layer-3 addresses" dialog arenot necessary.

If the NE shall be operated in third-party networks, it may be necessary to adjust an OSI-L3 addressmanually (manual mode). In order to avoid malfunctions, both the addressing scheme and the individualaddresses must be provided and carefully administered by the network operator. OSI Layer-3 addressesshould comply with the ISO 8348/Add.2 standard.

Mode

manualManual address assignment adjusted.

Routing level

A Routing Domain is divided up into individual areas.

An End System (ES) can only transmit or receive messages. The SOA can be an ES. The networkelements are Intermediate Systems (IS) which are also appropriate to pass on messages (routingfunction).

A Level-1 router can route only within its own area. If a Level-1 router receives a message determined foranother area, this message is passed on to the nearest Level-2 router. If there is no Level-2 router in theown area, the message is discarded.

A Level-2 router does not only know the IS and ES of its own area but als the Level-2 routers located inthe other areas. If a message is determined for another area, it is passed on by the Level-2 router of thesource area to the Level-2 router of the destination area (if necessary via several Level-2 routers).An area can also include several Level-2 routers. Level-2 routing between Level-2 routers is possible onlyif the corresponding Level-2 routers are directly interconnected (i.e. no via Level-1 routers).

RF/160 OI 4-79

Structure of the OSI Layer-3 address

The OSI Layer-3 address is composed of three parts, i.e. the Area address, System ID and NSAPselector.The Area address is used to address the sub-network to which the NE belongs.In the example below, addresses of the "ANSI NSAP address format" are used (AFI 39, IDI=ISODCC=840F [USA], DFI=80).Area address: 39000080000000000000000000The second part of the address (System ID) represents an unambiguous System Identifier which isunique in the entire Routing Domain.

Example: 96F100120000In the hexadecimal format, this address corresponds to Internet address "150.248.0.18".The third part of the address is the NSAP selector. It selects the transport layer as Layer-3 user. It isalways 01.On activation of the "manual" Layer-3 addressing mode, the automatic address assignment is excludedfrom the manufacturing number. In this case, a remote logon from the Operator Terminal is usually nolonger possible (only local logon).

Operating Instructions Alignment

RF/160 OI 5-1

5 Alignment5.1 IntroductionTo permit hitless protection switching, the system must be aligned. The alignment process compensatesthe different delays of all channels. Thus, the switch itself receives synchronous data and can switch overfrom one side to the other without any loss of sync. The reference used for calculating the delay is alwaysPR1. The present chapter describes how to align the entire system and how individual channels can bere-aligned. The alignment of a hot standby system will be described at the end of the chapter.Important:

When opening the window for the first time, errors may be displayed (since the system has not yetbeen aligned, there will probably be alignment errors). The alignment must be performed using STM-1signals without AIS. Otherwise this process will be interrupted. Ensure that no channel is injecting orreceiving an AIS signal. Also ensure that the channels are not blocked. For the alignment process, the"Automatic" setting option for protection switching must be active for all operating channels. Protectionchannels must be sent to "Occasional traffic (OT) - loose" or "No occasional traffic (OT)".After an alignment or test process, the protection switching configuration of the system must bechecked, because operating channels might be set to "Automatic off".

5.2 DisplayTwo different display modes are available, i.e. a graphical and a tabular display. Using the "Display"menu item, it is possible to switch over between these two display modes.

Both displays are subject to the following rules:� blue = transmit-side and receive-side protection switching link� green = active transmission (OP or PR)� red = faulty transmission� white = input box

Alignment Operating Instructions

RF/160 OI5-2

Graphical displayThe graphical display shows the individual transmission links sorted according to operating and protectionchannels. The transmit side (far end) is depicted on the left, the receive side with the local port on theright side.Depending on the system expansion, two N to 1 multiplexers (RPS-C, Radio Protection Switching) can beused to switch the operating channels to one protection channels. This is indicated by the verticalconnecting lines and colors. A mark at the crossing point shows the multiplexer switching status.If a channel is available, the alarm data are displayed in the first column. Otherwise, the backgroundremains dark grey.

Tabular displayThe tabular display of the alignment mask gives a compact overview of the channels and their statusesThe colors of the individual table cells are sorted according to columns and assigned according to thefollowing scheme:

Channel red Channel failed/disturbed and protection switching failed/disturbedgreen a) Channel OK or

b) Channel failed/disturbed, but protection switching OK

Measuring value red Channel not alignedgreen a) Channel aligned and protection switched or

b) Channel aligned and Tx-side protection switching prepared

PR1/PR2 statusred Channel failed/disturbedgreen Channel aligned and protection switchedblue Channel aligned and Tx-side protection switching prepared

Meaning of alarmsINT-A General alarm "Module defective" of the associated DPU module.INT-B General alarm "Module faulty" of the associated DPU module.Align Test switchover was not error-free. Channel is not correctly aligned.RPS-AIS The associated DPU receives AIS in the protection switching block

Important:When opening the window for the first time, errors may be displayed (since the system has not yet beenaligned, there will probably be alignment errors).The alignment must be performed using STM-1 signals without AIS. Otherwise this process will becancelled. Ensure that no channel is injecting or receiving an AIS signal.

Also verify that no channel is locked. During the alignment process, the "Automatic" option must be activefor all operating channels; protection channels must be set to "loose OT" or "no OT".After an alignment or test process, check the protection switching configuration of the system to ensurethat operating channels are not set to "Automatic OFF".


RF/160 OI 5-3

5.3 Overall alignmentThe overall alignment process can be started by clicking on the Settings | Align all menu items.The following request will be displayed:

Click the Yes button to start the alignment process. A status dialog displays which OP is tested withwhich PR all along the process:

If the process has been successfully executed, the following message will be displayed:

By clicking on 'Details', the delays between the PR1 reference channel and other channels will bedisplayed.


RF/160 OI5-4

All channels are now aligned and shouldn't display any more alarms:

5.4 Checking alignment data

A test is necessary to check the alignment data. This test can be started by clicking the Setting | Checkall menu items.

The following security request will be displayed:

Choose the Yes button to start the alignment value testing process. A status dialog displays which OP istested with which PR all along the process:


RF/160 OI 5-5

If the process has been executed successfully, the following message will be displayed:

By clicking on 'Details', the delays between the PR1 reference channel and other channels will bedisplayed. These delays may possibly deviate from those displayed during the alignment process.

All channels are correctly aligned.

5.5 Selective alignmentBy double-clicking the required channel, the following window will be displayed:

This channel can be tested or aligned only using the selected PR. The system protection switching test orsystem alignment is executed by selecting all channels. The 'Enhanced priority' option enables you tooverride the locked configuration of the selected channel(s).


RF/160 OI5-6

By double-clicking the delay option, the delay value can be changed (default value: 700 for N+Msystems):

By double-clicking on the right side of the delay box, the following window will be displayed:

OP manual configuration PR manual configuration

For more detailed information, please refer to DPU configuration.

5.6 Hot Standby or 1+1 without occasional traffic

In a 'Hot standby' or '1+1 without occasional traffic' configuration, only one DPU is available. Thealignment memory of this DPU is divided up into 2 parts to create two virtual DPUs (OP1 and PR1).

The default delay value is now 350.The configuration and alignment processes are identical with those of an N+M system.


RF/160 OI 5-7

5.7 Alignment errorsIf a channel could not be aligned, an error will be displayed. By clicking on 'Details', the errored channelswill display a "couldn't be aligned" message instead of the calculated delay value.

A faulty configuration in the far end (i.e. N+0) can lead to a system failure. In this case, check theprotection switching configuration of the far end and ensure that the N+M protection switching mode, hotstandby option or 1+1 configuration without OT has been selected.

The alignment process is interrupted if at least one of the DPUs detects an AIS on the receive side. In thiscase, an information box will be displayed.

Operating Instructions Measuring Values/Thresholds and Performance Counters

RF/160 OI 7-1

7 Measuring Values/Thresholds and Performance Counters

Using the Service PC, it is possible to request measuring values and enter thresholds for these.Only in the active menu and on updating the information displayed by the logic module, an overshootingof the threshold values entered is spontanously signalled. At the corresponding module, such an alarm isnot displayed.

RestrictionsThe number of QMP data sets (records) on a SISA0-N module is limited so that not all performancecounters available can be monitored with the full storage depth. As soon as the maximally adjustablenumber is exceeded, the network element will send a negative acknowledgement.Independent of the degree of system expansion, a total number of 19324 bytes are available for QMPdata sets (records). A 15-min. data set requires a memory capacity of 18 bytes, a 24-h data set 29 bytes.

In case of a terminal with 14+2 configuration, the following performance measuring points are accessibleat functional group level:16 x RTF or RTFE: 1616 x RRTF: 161 x PSU: 14These 46 points can be activated with a storage depth of 4 x 15 minutes and 2 x 24 hours. In addition, thestorage depth of three points can be increased to 100 x 15 minutes, that of ten points can be increased to30 x 24 hours.The total memory capacity occupied is calculated as follows:

QMPs x Storage depth : QMP data sets Memory capacity46 x 4 (15 min.) : 184

- 3 x 4 (15 min.) : - 12+ 3 x 100 (15 min.) : + 300

� Management, configuration and monitoring of the microwave radio system at module level� MSP Application SISA-V, Version � 2.09

8.2 Software download to system modules

Using the menu items

Hardware view

Modules

Administration

File transfer

all modules except SISA-0/N4 and SISA-KR can be loaded with new application software. For thispurpose, an appropriate control file (extension .CTL) must be available, which is used by the downloadroutine to determine the application to be downloaded to the individual modules.A document with detailed SW download instructions is supplied with each system software release.To avoid a bus overload, NE alarms should not be requested during the download process.

8.3 OSI parameter file transfer to the ECC Gateway Module


Hardware view

Modules

Administration

File transfer

new OSI parameters can be downloaded to the ECC Gateway module. For this purpose, the OSI.CTLand OSI.XML files must be available in a directory.The download routine uses the OSI.CTL control file to extract the name of the OSI.XML parameter file.Depending on the size of this parameter file, the file transfer may take several seconds to some minutes.After a self-test of the ECC Gateway module, the OSI stack starts to operate with the new parameters.

4 The SISA0 application is required for this purpose.

Software, Equipment and Configuration Management Operating Instructions

RF/160 OI8-2

The parameter file can be edited, so that any OSI parameter values supported by the ECC Gatewaymodule can be downloaded.Caution: In order to be able to set up an ECC connection, the OSI parameters of the ECC Gatewaymodules involved must be identical. This prerequisite is not fulfilled before all ECC Gateway moduleshave received their new parameters. This means to download parameters to an ECC Gateway modulelocated in an NE addressable only via the ECC, the corresponding parameters must first be downloadedto this remote NE before they can be downloaded to the ECC Gateway module located in the local NE.

8.4 OSI parameter upload from the ECC Gateway moduleUsing the menu items

Hardware view

Modules

Administration

File transfer

the OSI parameters used by an ECC Gateway module can be uploaded. For this purpose, theOSIUPL.CTL file must be available.The upload routine uses the OSIUPL.CTL control file to extract the name of the OSI.UPL parameter file.Depending on the size of the parameter file, the upload process may take several seconds to someminutes. The OSI.UPL file is saved to the same directory as the OSI.CTL file.The upload file is composed of three parts. Part 1 (ACTUAL OSI-PARAMETERS) shows the OSIparameters actually used by the ECC Gateway module. Part 2 (INITIALIZATION FILE) shows thepermanently stored OSI parameters used for initialization after the first OSI parameter file transfer. Thesecan be extracted and transferred to further NEs. Part 3 (LOG FILE) shows fault reports that may occurwhen the stored parameter file is edited.

9.1.1 Safety instructions

For replacing modules, please note the following instructions:

On the fuse panel, switch off the power supply unit provided for the modules you want to replace. Donot forget that the DPU, Controller, RPSI, SPI-el. and SPI opt. modules of the Modem Unit aresupplied redundantly.Pull out or plug in the control and operating voltage cables on the Modem Unit, OHAU, transmitter andreceiver modules only with the power supply switched off (exception: RPS-C and RPS-H).Extract or insert the following modules only with the power supply switched off:

Modulator = MD (in Modem Unit)Demodulator = DM (in Modem Unit)SOH Access = SOHA (in OHAU)Power Supply = PS (in OHAU and Modem Unit)

Since it is necessary to replace modules in operation, the relevant processes are described in thischapter in such a way that only the corresponding modules can be replaced with the power supplyswitched on.

2. In case of redundant systems, disable both the channel to beexchanged and the automatic switchover function.

The corresponding channel and protecting switchingfunction must be disabled in both the local station andfar end.

3. Switch off the circuit breaker of the corresponding channel.

With XPIC systems, bit errors will occur for up to5 s in the XPIC partner channel.In case of non-redundant systems, transmission will beinterrupted.

4. Replace the transmitter.- Set up again all connections except the IF cable connection.- When doing this, ensure that the connectors are correctly positioned.

5. Switch on the channel again.

In case of XPIC systems, bit errors will occur for up to5 s in the XPIC partner channel.

6. Download the configuration using the appropriate backup file. If thisfile is not available, configure the unit manually.– Deactivate the ATPC function.– Set the output power to its minimum value.

7. Connect the IF cable.This may temporarily lead to bit errors in the direct adjacent channels.

8. Activate the ATPC function.

17.13.1 Mapping service channels onto SCU instances and channels

Microwave terminals are configured as network elements WEST. Regenerator stations are alwayscomposed of two terminal network elements, i.e. one NE WEST and one NE EAST.All service channels, except those of RFCOH East, are mapped into SCU instances of networkelement WEST. The instance no. itself depends on the address of the associated OHA Unit in thesystem.The distinction between "East“ and "West“ for service channels is independent of the network elementand indicates the direction of the service channel signals within one terminal, "West“ being the radiodirection (from/to the radio hop) and "East" being the line direction (from/ the baseband interface).

Operating Instructions Annex 3: Co-channel Operation with XPIC

RF/160 OI 18-1

18 Annex 3: Co-channel Operation with XPIC18.1 GeneralThe present chapter describes the behaviour of MDRS 155 E systems in co-channel operation oncrossed polarizations (CCDP mode) in case of equipment failures.

18.2 Functioning of a CCDP systemFig. 18-1 shows a simplified block diagram of a CCDP microwave radio system. The transmitters "TxH" and "Tx V“ transmit two independent (STM-1) data signals with the same frequency on crossedpolarizations (H = horizontal, V = vertical). In the transmission channel, the signals are time-variablyand frequency-selectively distorted on the respective polarization due to fading. This is shown in thebelow block diagram by the Hhh(f) and Hvv(f) filter functions. In the CCDP mode, there are additionalcross-talk components between the two polarizations shown by the Hvh(f) and Hhv(f) functions.

Fig. 18-1: Block diagram of a CCDP system

On the Rx side, the signals are first passing the receivers "Rx H“ and "Rx V“. With the ATPC(Automatic Transmit Power Control) circuit activated, the transmitter output levels are controlled toobtain a constant Rx power. In normal operation, the control circuits on both polarizations workindependently of each other.The downstream demodulators represent a simulation of the transmission channel used tocompensate the signal distortions which are occurring on the latter. The adaptive channel equalizer(ATDE = Adaptive Time Domain Equalizer) compensates the linear distortions of the signals on thetwo polarizations. The frequency-selective cross-talk components between the two polarizations areeliminated by the cross-polarization equalizer (XPE).

18.3 Behaviour in case of radio hop failuresIn an undisturbed transmission channel, the four channel transmission functions shown in Fig. 18-1are constant irrespective of the frequency used. Hhh(f) and Hvv(f) represent the respective radio hopattenuation. The cross-talk components Hvh(f) and Hhv(f) correspond to the cross-polarizationdiscrimination (XPD) of the antenna and are typically 35 dB. Under these circumstances, systemsoperating with 64 MLQAM and 128 MLQAM modulation permit an error-free transmission of the datasignals even without the XPE function.

Radio hop failures are in most cases caused by fading effects. These are normally composed of afrequency-independent increase in the radio hop attenuation (flat fading) and a frequency-selectiveattenuation (selective fading). These flat fading portions in the two polarization planes arecompensated by the ATPC circuit and a control amplifier in the receiver. The fading events on therespective polarization plane are accompanied by depolarization effects which are normally alsofrequency selective. The adaptive filters (ATDE and XPE) in the demodulators are used tocompensate these distortion and cross-talk effects.The fading events on the individual polarization planes and the associated depolarization effects arecorrelated with respect to each other. However, the interference factors are so manifold that a generalstatement regarding the correlation strength is not possible. In order to permit the maximum protectionfor any channel situation, the various adaptive filters and ATPC circuits must operate independently ofeach other in the distorted channel.In contrast to the equipment failures described in section 18.4, fading effects do not occur suddently,but slowly. The control circuits of the ATPC, receiver, channel and cross-polarization equalizer aredesigned and adapted to each other so that they can follow the highest radio hop dynamics to beexpected without any delay.The adaptive channel filters are able to equalize selective fading events and the associated cross-polar cross-talk effects up to the limits specified by the signatures. Fading parameters exceedingthese limiting values lead to an increase in the bit error ratio up to a level, which exceeds the SESthreshold as defined by ITU-T Rec. G.826 and results in a failure of the synchronization devices. Inthis case, the DPU module injects an AIS into the corresponding STM-1 signals.

18.4 Behaviour in case of equipment failuresDue to the relatively strong cross-polar coupling, failures occurring in a channel of the CCDP systemmay affect the transmission on the crossed polarization. In this conjunction, equipment failures areparticularly critical, since they normally occur spontaneously, whereas the contol circuitscompensating such effects cannot react without delay.In CCDP systems with cross-polarization equalizers there is a basic difference between equipmentfaults on the transmit side and those on the receive side. The following sections describe theconsequences of such events and the corresponding system reactions.

18.4.1 Tx-side failureFig. 18-2 shows the situation of an equipment failure on the Tx side, which occurred on the verticalpolarization in the example depicted below. This leads not only to a transmission failure on the verticalpolarization, but also to a breakdown of the interference coupling from the vertical to the horizontalpolarization. However, in this case, signal energy is still flowing in the opposite direction (H to V). Evenin case of a high XPD factor, this energy is normally sufficient for the receiver RxV and thedownstream signal processing units to synchronize themselves to the signal radiated in the horizontalpolarization plane and to regenerate it without any bit errors.

In STM-1 signals, a polarization identifier is transmitted in addition to the radio hop identifier. Usingthis information under the fault conditions described, the system can identify a synchronization to thecross-polar data signal. The corresponding alarm is displayed by the DPU/RPS STM-1 module asradio hop ID alarm. It causes both cross-polarization equalizers, XPEhv and XPEvh, to be switched off,so that there can be no more overcouplings on the XPE paths. In consequence of the radio hop IDalarm, the DPU module of the vertical polarization plane injects AIS into the STM-1 signal transmittedin the line direction. The disconnection of the cross-polarization equalizers is signalled in thedemodulator module as "XPIC not in operation" alarm.As soon as the faulty transmitter (V) is operational again, the system automatically returns to normaloperation.In case of a strong cross-polar coupling in the transmission channel, a spontaneous equipment failureon the Tx side can lead to short-term transmission failures on the crossed polarization, since theinternal control loops cannot react to the sudden change in the transmission parameters without delay.

18.4.2 Rx-side failureThe behaviour of the MDRS155 E systems in case of an equipment failure on the Rx side stronglydepends on which components are affected. The worst case occurs in case of a failure in the RFpreamplifier section, while all other circuits continue to operate correctly. Fig. 18-3 shows the situationresulting from such a failure.

In the RxV receiver, an insufficient level is detected. If the ATPC circuit is active, the signal power ofthe TxV transmitter is increased up to its maximum value (e.g. 30.5 dBm), whereas the power of thehorizonal channel, i.e. of the undisturbed transmission channel, remains at its minimum value (e.g.10.5 dBm). The XPD in the horizontal channel deteriorates by the difference between the two transmitlevels, i.e. it is reduced in the present example from 35 dB (typical antenna XPD) to 15 dB.For 64 MLQAM and 128 MLQAM transmission, this S/N ratio is not sufficient for a correct datatransmission without XPIC. Simultaneously, it is no longer possible to compensate the cross-talkeffects Hhv(f) from the vertical to the horizontal polarization in the demodulator, since thecompensation path XPEhv is affected by the interrupted signal transmission.The faulty RxV receiver continues to control its output level to the nominal value. The signal, however,contains only noise. The control loops in the demodulator of the vertical polarization cannotsynchronize themselves any more to a modulation signal. This results in a shutdown of both XPEfilters. Thus, it is prevented that the receiver noise is transferred via the XPIC to the undisturbedchannel and that its signal quality is additionally affected.As soon as the demodulator can no longer synchronize, a timer is started in the receiver. The runtimeof this timer can be adjusted in the Hardware View of the MSP in the "Main Receiver“ module underthe "Error timer" configuration option. After expiry of the timer, the transmit level is controlled to a value

defined for this fault condition. This value must be adjusted in the Configuration window under the "Txlevel after error timer has expired/Manual Tx level" menu item.

Using these settings, the transmitter of the faulty channel can be reduced to its mininum level aftertimer expiry. Thus, the S/N ratio in the channel not affected by the equipment failure can be improvedand bit-error-free transmission can be restored with a radio channel not affected by fading events andantennas with a sufficient XPD factor.The following settings are recommended for the ATPC timer and Tx level under fault conditions:� Error timer = 4 min.� Tx level after error timer has expired/Manual Tx level = minimum value

Reason:The required availability of 99.999% corresponds to an outage of 5.25 min./per year. This outage iscomposed of a number of short failures (due to events occurring on the radio hop such as fading orprecipitation). It is not expected that a single event could already last for this entire permissible outage.Thus, when entering 4 min. as default value, it should still be possible to distinguish between failuresdue to fading and failures due to equipment defects. However, the selection of a value <4 min. canlead to a longer outage in case of failures caused by fading effects, since in this case, the Tx level willpossibly be reduced before the fading event disappears. This would result in an additionaldeterioration of the S/N ratio.

18.4.3 Failure of the ATPC control channelIn case of a transmission failure in the return direction, the ATPC control information of the TxH andTxV transmitters will get lost (see Fig. 18-1). The system behaviour in this case can be configured inthe Hardware View of the MSP in the "Transmitter" module under the "ATPC fault processing" menuitem.If the "XPIC dependence" option is active, both transmitters operating at the same frequency and oncrossed polarizations, are simultaneously controlled up to their maximum output level, as soon as atleast one of the two ATPC control channels fails. If this option is not active, only the transmitteraffected by the control channel failure will be controlled up to its maximum level, while the transmitteron the crossed polarization will continue to operate normally.

In the CCDP mode, it is recommended to activate the "ATPC dependence" option.

As soon as the ATPC control channel fails, a timer is started in the transmitter. The runtime of thistimer is adjustable via the "Error timer“ option. After expiry of this timer, the transmitter affected by thecontrol channel failure is controlled to the value adjusted in the same configuration window under the"Tx level after error timer has expired" option. At the same time, the transmitter not affected by thecontrol channel failure returns to normal operation (provided that the "XPIC dependence" option hasbeen activated).It is recommended to made the settings as described in section 18.4.2, i.e.� Error timer = 4 min� Tx level after error timer expiry = minimum value

For reasons why these settings should be made, see section 18.4.2.

This system behaviour is primarily based on the assumption that the ATPC control channel has beeninterrupted in the return direction due to strong fading effects, so that no information on the Tx powerrequired is available. In order to avoid negative effects on the go direction, the power of the transmitteraffected is increased up to its maximum value. Simultaneously, the cross-polar transmitter iscontrolled up to its maximum transmit power (XPIC dependence = ON), since the cross-polar S/N ratioin this channel would otherwise deteriorate by the ATPC control range. Thus, it is possible to createthe best prerequisites to maintain the availability of the transmission link in the undisturbed directioneven in case of fading effects eventually occurring.After expiry of the timer it is assumed that not a fading event, but an equipment failure has led to theinterruption of the control channel. In this case, it is reasonable to control down the transmitter to itsminiumum output level in order to minimize the noise level affecting the transmission channels stilloperational.
