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.

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.

Parent SBL
Child SBL(1) (2)
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.

2.5 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 :

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”.

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

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.
