The first steps of each installation is the visual check of BTS mechanics and electrics: • BTS rack (rack fixing, fixed boards), • damage to rack or shelter (paintwork, dents), • correct insertion of modules, • system / rack cabling, • grounding, • main fuses, • external interfaces - power supply, antenna and Abis wiring.

3.2 COBA / COSA impedance Depending on the COBA version, the appropriate line impedance is set via DIP switches or is defined in object CREATE BPORT, parameter LIMP. The settings for LIMP are: • balanced for 120Ω/100Ω (only COBA4P12)
• coaxial for 75Ω (only COBA4P12)
• AccDIP for According to DIP Switches (mandatory for COBA2P8) On a COBA4P12 the adjustment is performed by software. So the value must be ‘Imp100or120Ohm’ or ‘Imp75Ohm’. On a COBA2P8 the adjustment of the impedance is done by DIP switches. So the only accepted value must be ‘AccDIP’. There are DIP Switches for impedance setting for each PCM line that can be connected, that means in case of COBA two switches.

3.3 Cable loss and DIAMCO / DUAMCO The dip switches on the front side of DIAMCO / DUAMCO determine whether the DIAMCO / DUAMCO run in AMCO or in MUCO mode (Note: No switches are available for TMA). In MUCO mode, the attenuation must be set to 6 dB (total) attenuation on the antenna cable between TMA and DIAMCO / DUAMCO.

Cascading of multicouplers Multicouplers can be cascaded in order to save RX antennas. Max. 2 cascades are allowed. The following table contains all possible cases.

The first device in the chain works in AMCO mode, the cascaded devices in MUCO mode. Thus, for TMA installed, all other devices have to be set to MUCO mode. If the cascaded element is a DUAMCO a special cable with SMA connector at one end and a 7/16 connector at the other end is used.

6.1 CU and FCU Different types of carrier units (CU) can be supported in the BTSE. The same LMT object CU is used to create GCU (carrier units that support GMSK) and ECU (EDGE CU). In case of FlexCU (FCU) another LMT objects are used. Carrier Units and Combiner objects can be created in the similar way as before. The object folder in the tree view has to be clicked with the left mouse button. Then the command Create CU is offered.

The FlexCU board is modeled with the HMO instances: • FCUMAIN • FCUTR The FCUMAIN instance represents that part of the board which performs board related activities and the FCUTR instances represent carrier (TRX) specific activities. The FCUMAIN has to be created once per FCU module and gets the same number as the CU slot (FCUMAIN:n). If the FCUMAIN mode is set to doubleCUmode, two FCUTR objects have to be created. They get the number FCUTR:2*n and FCUTR2*n+1. In case the FCUMAIN:n is set to singleCUmode, only one FCUTR:2*n object is created.

6.2 DUAMCO Each DUAMCO 2:2/4:2/8:2 or FDUAMCO module contains two Low Noise Amplifier in the RX path and two Antenna Supervision Units in the TX path. Optionally there can be two TMA power supply and alarm supervision units. For each of these functions there are corresponding HMOs for representing the configuration: • DULNA • DUVSWR • DUDCTMA
Numbering: The first DUAMCO module in the rack is put in the first slot, the second DUAMCO in the second slot and so on. This means that objects DUAMCO_LNA 0 and DUAMCO_LNA 1 are always associated in the first slot within the rack, DUAMCO_LNA 2 and DUAMCO_LNA 3 in the second slot and so on.

6.5 DUDCTMA To improve the Receive Signal, optionally you can use a Tower Mounted Amplifier (TMA). The TMA is outside of the BTSE mounted very near to the receive Antenna to Amplify the weak received signal from MS directly. If there is TMA installed, the HMO TMA has to be created. To give Power supply for the TMA and to deliver the alarm in case of TMA failure via the CAN bus to the Core, in the DUAMCO the object DUDCTMA has to be created.
Numbering: The numbering depends on the slot where the TMA is wired to. TIP LNA predecessor has to be used in the object DULNA if the TMA is used on the corresponding slot. Example in DUAMCO4:2 in slot 0 there is TMA used. The objects TMA:0, DUDCTMA:0 has to be created. The DULNA:0 is created an the LNAPRED is set to TMA:0.

6.6 Setting BTSE attributes One of the most important BTSE attributes is the Sales Unique Name. The SALUNAME together with the TEI is used for uniquely addressing the BTSM from the BSC. For a proper working of Remote Inventory the SALUNAME and the BTSEPOS (BTS equipment position) have to be set correctly. The ASCII 11 character string for SALUNAME is defined by SIEMENS central service TAC 3 and provided to the commissioners by local TAC 2. The Abis interfaces can be terminated without Overvoltage Protection for indoor applications (with an ABISCON ) or with an optional Overvoltage Protections (OVPT) which protects the boards inside the BS-240XS against overvoltage (parameter OVPTINS). If the connection point for the Abis line (e.g. NTPM or microwave equipment) is outside the building containing the BTSE is installed, an OVPT module must be installed .

6.9 LAPDLE creation The object LAPDLE identifies the time slot on Abis used for communication between BSC and BTSE (as viewed from BTSE). Its counterpart on the BSC side is called "LPDLM". The LAPD links are either all 64 kbit/s (3 and more TRX per BTSE) or all 16 kbit/s (max 2 TRX/BTSE), and either all satellited or all not satellited. Note: The object "LPDLM" on the BSC command tree indicates a time slot, which may carry both LPDLM and LPDLR type LAPD signaling. The settings for LAPDLE (BTSE commissioning) and LPDLM (BSC database) must be consistent.

The BTSE is switched to phase 3 either with the • "Switch" button (LMT Evolution icon or • command "Connbsc" (connect BTSM to BSC) in the BSS FUNCTIONAL, BTSM
object. After switching from phase 2 to phase 3 the LMT session is closed and a new logon is required. Now, the LED on the COBA show

9 Generate backup files
Siemens Commissioning BS24x/4x
MN1784EU12MN_0001© 2002 Siemens AG
62
In order to save the latest BTSplus configuration, a backup copy is generated and stored on site, e.g. on a floppy disk. By default; all files necessary to perform the backup and restore procedure are stored in subdirectory C:/Siemens/LMTxxx/BkBts/BTSplusyy on the LMT hard disk (where yy can be 16, 17 or 18 to indicate BR7.0, BR8.0 or BR9.0 SW version used in the BTS, respectively). BTSplus backup files are generated in phase 2 or 3 by performing the following steps: • start BTS Backup tool (from LMT Evolution , menu View) • Select the command GET (button or file menu) The objects and attributes of the BTSE are stored in up to 8 TXT files (e.g. GETBPORP) describing the current configuration. For the restoring these files are converted into script files (e.g. script1p.lmt) generated. These script files should be backed up on CD and left in the BTSE so that you can use them in case of a COBA failure.

Exercise Title: BS24x/BS4x commissioning
Objectives: Understanding the Commissioning Procedure for BTSPLUS
Pre-requisite: None
Task Perform a BS24x/BS4x commissioning according to the procedure described above.
Query The following information must be collected before formatting COBA FEPROM: • Terminal Endpoint Identifier TEI • SalesUniqueName SALUNAME • LAPD signaling channel LAPDLE • line configuration (star, multidrop chain, loop) • Cell configuration (BTS number) • software version (SWLH, SW version) Additional steps in order to bring the system down: Lock BTSM and disconnect (by command) BTSE from BSC From LMT, enter the following commands: LMT tree: MANAGED-ELEMENT --> BSS-FUNCTIONAL --> BTSM Command: LOCK BTSM Name: NAME=BTSM:0 Attributes: none Submit Command line: LOCK BTSM: NAME=BTSM:0;

LMT tree: MANAGED-ELEMENT --> BSS-FUNCTIONAL --> BTSM Command: DISCBSC Name: NAME=BTSM:0; Attributes: none Submit Command line: DISCBSC BTSM: NAME=BTSM:0; BTSE switches from phase 3 to phase 2. A new Logon is necessary. Format COBA Flash EPROM From LMT, perform the following steps: LMT tree: MANAGED-ELEMENT --> BSS-EQUIPMENT --> BTSE Command: FORMAT BTSEP FLASH Name: NAME=BTSE:0; Attributes: none Submit Command line: FORMAT BTSEP FLASH: NAME=BTSE:0; This procedure requires about 1-2 minutes. The BTSplus switches from phase 2 to phase 1. A new Logon is necessary. Power off the BTSE Switch off all fuses. Follow now the steps described in this chapter to do the commissioning.
