Objective : to be able to handle the Security Blocks (SBL)

Program : 2.1Definition2.2 SBL States2.3 SBL Hierarchy2.4 Operator Commands2.5 Relationship between SBL & RIT2.6 TMA Settings




2.1 Definition

SBL Definition

Security Block (SBL) 1/2

An SBL represents an entity of the BSS which is manageable by the O&M, it can be:

an equipment (e.g. RA)a resource (e.g. BTS_TEL)A support resource (e.g. RSL)

One SBL can be carried by several RITsExample: SBL RA

One board can carried several SBLsExample: SBL SUMA board

Here you find the SBLs classified according to domains ( “equipment”, “resource”, “O&M”, and “support resource”) At the OMC-R TMN compliance begins with modeling of Managed Objects: physical boards, logical resources links between physical boards & logical resources.

2.1 Definition

SBL Definition

Security Block (SBL) 2/2

A SBL is identified by the following parameters

Unit type (e.g.: “BTS”)Unit number (e.g.: 1…255)SBL type : this is the name of the SBL (e.g.: “TRE”)SBL numberSBL sub number: (represents the number of a SBL which is part of another SBL.)

An SBL is identified by the following parameters :

Unit type : Gives the SBL grouping inside the BSS. The following items are allowed:“BTS”

Unit number : Identifies a unit replicated several times in the same BSS. For instance, a BSS can include up to 255 BTSs. The unit number of the SBL having “BTS” as SBL type is : 1... 255. The unit number of SBL having “BSC” as SBL type is always 1.

SBL type : This is the name of the SBL (e.g.:”BTS” or “BSC”).

SBL number : Identifies a SBL replicated several times in the same BSS.

SBL subnumber : Represents the number of a SBL which is part of another SBL.




2.1 Definition

RIT Definition

Replaceable Item (RIT)

An RIT is the smallest physical module that can be replaced in case of fault. (can be a board for example)

An RIT is identified by the following parameters:Unit type – name of the board or moduleUnit numberRackShelfSlot

An RIT is identified by the following parameters which give the location inside the BSS :

Unit type : can be :BSC BTSTC

Unit number : Identifies a unit replicated several times in the same BSS. For instance, a BSS can include up to 255 BTSs: the BTS unit number is 1 ... 255.

Rack : identifies the rack with a rack number

Shelf : identifies the shelf in the rack.

Slot : identifies the slot in the shelf.

An RIT is also identified by an RIT type which defines the RIT function. The RIT type is used by the maintenance personal when replacing a failing unit. An RIT is only replaceable by another RIT which has the same RIT type or by an RIT which has a compatible RIT type.

If the parent SBL (B in Case 1; B or C in Case 2) enters the state IT/FIT from any state OPR/FOS/FLT/EF, the state of the child SBL is as follows :

If the parent SBL is in the BTS : the child SBL’s state is reset to ‘IT’, except if in state ‘OPR’ or ‘FOS’ or ‘FLT’state

If ever there is a persistent problem on the child, an alarm/state change will be re-issued for the child.

Remark:This is a dependency from top to bottom : the state of a child SBL has no effect on the state of its parent.

2.4 Operator Commands

SBL Operator Commands

Handling of SBLTo ensure the maintenance of the BTS, the operator needs to check or modify the SBL conditions from the BTS-Terminal.

Using the menuCommands / SBL Management

Select the SBL you want to handle and then apply one of the commands selected from the right side of the screen






Maintenance operator commands

Read : to get the SBL State

Init : It allows the setup of a functionality. This command applies to an SBL which was disabled before

PurposeReactivate the functionality of a target SBL

ImpactWhen the initialisation has been successfully achieved, the SBL should be able to handle its functionality







Disable : It allows to kill the functionality of an SBL

PurposeInhibit the functionality of a target SBL and filters alarmsThe Wait Traffic Clear parameter introduces a delay into the command executionThe traffic may be stopped in a clean way

ImpactThe context is lost (calls / signalling)







Restart : It allows to restart a functionality

PurposeBuild up a function supported by SW without SW download (a self test is executed before SW download)

ImpactContext is kept







Reset : It allows to kill and set up a functionality in sequence

PurposeEscape from a situation where the behaviour is doubtfulThis command may be seen as a combination of Disable and Init

2.5 Relationship between SBL & RIT

Relationship’s menu

For the maintenance, it is very important to determine the relationship between the SBL and the RITThe following menu can be used :

Show / SBL Mapping

One SBL is not necessarily associated with one RIT. For example :Several SBLs may correspond to the same RIT(e.g.: SUMA RIT for SBLs with “OMU” or “CLLK” as SBL type).A SBL may correspond to several RITs(e.g.: SBL with “BTS” as SBL type).A SBL may correspond to no RIT(e.g.: SBL with “BTS-O&M” as SBL type).

In this example, OMU1 is unit UT_TR_CLK 39BTS rack ASub rack 2Slot 7

The rule to determine the physical position of a board having its physical address (ex : 39 in this case) is as following :

Physical Address = 16x(Sub rack Number) + Slot Number




2.5 Relationship between SBL & RIT

Relationship’s menu

For the TWIN TRE it is also possible to determine the relationship between the SBL and the RITIn this case the RIT is called TGT09 (for TWIN TRE in 900MHz band) or TGT18 (for TWIN TRE in 1800MHz band)The following menu can be used :

Show / SBL Mapping

One SBL is not necessarily associated with one RIT. For example :Several SBLs may correspond to the same RIT(e.g.: SUMA RIT for SBLs with “OMU” or “CLLK” as SBL type).A SBL may correspond to several RITs(e.g.: SBL with “BTS” as SBL type).A SBL may correspond to no RIT(e.g.: SBL with “BTS-O&M” as SBL type).

In this example, OMU1 is unit UT_TR_CLK 39BTS rack ASub rack 2Slot 7

The rule to determine the physical position of a board having its physical address (ex : 39 in this case) is as following :

Physical Address = 16x(Sub rack Number) + Slot Number




2.6 Twin TRE Settings

TWIN Configuration

The Twin TRE module can be used as two independent TREs or as a singe TRE with improved performance. The following menu can be used :

Commissioning -> Edit TWIN Configuration




2.7 TMA Settings

For TMA settings the following menu can be used :Commissioning / Edit TMA Setting

The new Evolium™ Antenna Network evolution modules (ANCevolution & ANBevolution) provide higher functionality (TMA DC power supply & TMA supervision included).







Objective : to be able to handle the Security Blocks (SBL)

listed in this section.Message Identity The identity number given to the alarm message stored in the database.Event Time The time the message was issued at its source or received at the BTS LMT.Classification The characteristics of the alarm, consisting of:

Alarm Class name and number - as shown in the Alarm DictionaryClass 1: CLK AlarmsClass 2: OMU AlarmsClass 3: SW-AN Alarms……..Class 11: BTS-TRANS Alarms

Alarm Type name and number - as shown in the Alarm DictionaryCommunication - a problem with a procedure or process used to convey information from one point to another in the network.Quality of Service - degradation in the quality of service in the network.Processing Error - a software or processing fault.Equipment - an equipment fault.Environmental - a problem in the enclosure containing the equipment.

Alarm Number - dependent on the Alarm Class and Type. See the appropriate dictionary entry for the valid alarm numbers for a particular alarmAlarm Condition - has one of the following values:

begin - alarm on. For fatal failures, the affected SBL changes state to FLT or FOS. For non-fatal failures, the affected SBL changes state to FITend - alarm off. Indicates the successful recovery of the system. The affected SBL may not change state if other alarms related to the SBL are onevent - occurrence of anomaly. No action is required unless it occurs frequently. Event alarms are of short duration and the affected SBL does not change state. The system retry/recovery mechanism has cleared the fault.

Exercise 3

We know that a main element (which normally allows the communication with 8 subscribers) is now in a very bad state :

Using the BTS Terminal find the problem, analyze the situation and find out the position of the physical suspected element.Following the procedure in the “BTS Corrective Maintenance Handbook” replace the RIT.

Preparation :Choose a TRE without BCCH if it’s possibleSwitch OFF then ENABLE a TRE using the breaker in front of the TRE.

Answers :Find it : Monitoring / SBLs States

Monitoring / AlarmsFind at the position :

Click twice on the alarm and the detailed message appears with the indication of the physical position.Or : Show / SBLs Mapping and choose the suspected TRE

Replace the RIT following the procedure in the “BTS Corrective Maintenance Handbook” .




7.3 Fault Handling

Exercise 4

For several days, we have incurred many problems with the 3 FAN units below the sub rack 3 (for a Medi 3 x 1), below the sub rack 1 (for a Mini). We have already replaced these FANs but it is now certain that the problem is due to a common element of these FANs.

Following the controlling procedure in the “BTS Corrective Maintenance Handbook”, change this suspected RIT.

Answer: The RIT to be changed is the FACB Board on the back panel 3 (Medi) or 1 (Mini).

Show / SBLs mapping.Click on RIT, then on FACB A 3 0 (3 means subrack 3 - Medi) or FACB A 1 0 (Mini).Note the corresponding SBL (CCF n) that it will be necessary to disable later.Do the same thing in order to note the TREs that it will be necessary to extract.The “BTS Corrective Maintenance Handbook” procedure will ask you to disable the corresponding RA, so it is necessary to know the RA associated to the TREs of the subrack 3 or 1.To do that:

Show / Sector mapping.

Follow the “BTS Corrective Maintenance Handbook”.




7.3 Fault Handling

Exercise 5

Using the BTS Terminal, the frequency meter and the appropriate cable, perform the clock measurement following the EVOLIUM BTS Corrective Maintenance Handbook procedure.

Calculate the frequency shift (in hertz) for one step on the DAC (Digital Analogue converter) used in the SUMP/(A) through the BTS Terminal. This will be helpful for you in the future in order to tune the clock frequency.

Using the “BTS Corrective Maintenance Handbook” procedure perform the tuning of the clock.

Answers :Setting / Transmission / OCXO Adjustment.

Set a new value (1000 for example) then click on “Transmit” .Write down the frequency read on the frequency meter connected on clock out on the Connection Area (Top of Rack).Set a new value (3000 for example) then click on “Transmit”.Write down the new frequency.From this two measurements calculate the frequency shift.

Example :1000 2.1666655 Mhz3000 2.1666673 Mhz

1 step is 1.8 Hz/2000=0.9 MhzTo save the new best value in EEPROM when the measurement is OK :Click on "Save New Best Value as Config Best Value", then transmit.

Exercise 6

Test the OML auto-detection feature .

Preparation :Reset the current Transmission Settings from:

Settings/Transmission/Board Configuration.Check with the OMC-R operator that the Qmux address is the same with the one declared at OMC-R site.Reset the BTS.

Answer :After the BTS reset, due to the OML auto-detection feature, the Transmission Configuration should be automatically downloaded by the BTS from the BSC.




7.3 Fault Handling

Exercise 7

Using the BTS Terminal, perform a measurement of the VSWR.Is the result window dynamic ?

Justify .

Answer :

Cmds / SBL management/Disable RA x -> in SBL Module States window should be no VSWR value for RA x

Commissioning /Initialisation/Single Sector -> “Edit Frequencies” window appears and you have to choose the ARFNs

because you are now in “on-line commissioning” status -> still no VSWR value for RA x

Commissioning/VSWR Measurement/Start -> the TRE connected to RA will emit and in “VSWR Measurement /Threshold

Definition” window you will get the “VSWR measurement received” message-> consequently the result for VSWR for RA x should appear in “SBL Module States” window

In VSWR Measurement /Threshold Definition window you press “Stop” -> the result for VSWR for RA x should disappear from “SBL Module States” window -> So you realise the result window is dynamic.

Commissioning/ End commissioning




7.3 Fault Handling

Exercise 8

Understanding RA SBL numbering. (on Medi 3 x 1)

Answer:Check the RA / TRE assignment and physical positions as well as ARFCN / TRE assignment - diagram 1. Show / Logical HW characteristics.

Show -> HW config for RAs (physical positions of ANX/ANY) and for TREs (physical positions and associated sectors).

Reset TRE on sector 2 to confirm its physical position.

Tune the physical sector p on logical sector 3 then tune the physical sector q on logical sector 2

Using the BTS Terminal :

Cmds/Modify HW Configuration

Commissioning/Edit Sector Mapping -> change the sector mapping

Cmds/End Modification of HW Config

Reset the OMU.Using the BTS Terminal, identify the impacts and write them down (2). See next page .Reset TRE on sector 2 to confirm its physical position.
