Switch OFF the BTS cabinet and disconnect Abis connectors from DDF before offline start Disconnect the Abis connector from The DDF Switch ON the BTS cabinet breakers and connect the Laptop with BTS User Name “COMMTE” Password “COMMTE” Communication Port setting OR After connecting this window will be appear Go to Configuration-> BTS-SW Download-> to download BTS software After BTSSW download this window will appear Go to offline Files and select First File of Master File. Go to offline Files and select First File of DDL file. Click ok to start downloading SW BTS software starts to download. All these Files are downloaded Go to Configuration BTS commissioning Click start commissioning Edit Qmux Address Edit sector Mapping Check All Twin TRE’s. Click End Commissioning Click > Hardware setting>>Begin HW modification Go to configuration> BTS commissioning Go to start commissioning> Edit Q1 Address, Edit Sector Mapping and Twin TRA setting as in offline. Go to configuration> Hardware setting>“End Modification” to end online commissioning Online commissioning steps  Connect the Abis connector at DDF by verifying Tx/Rx cable properly.

 OML will be established after primary Abis has      connected to DDF. Give hard reset to BTS after OML has established. Put site on Downloading from OMC. O&M will be established as downloading completes. Connect Laptop to BTS MMI port. Go to configuration>Hardware setting>Begin Hardware modification.

Online commissioning steps  Go to configuration>BTS commissioning>start        commissioning. Edit Qmux Address Edit sector mapping Check all Twin TRA setting.

Click end commissioning and shift all modules from selected modules to available modules. Go to configuration>Hardware setting>End Hardware modification. Click “yes” when an automatically hardware modification window appears. Hw Audit will be run and all Hardware will be shown after sometime. ON Line Commissioning Completed Successfully.

Troubleshooting  If a TRE or combiner is in “Not Operational” or “FOS” state then        disable it then initialize it by using “init” command. If TRE or combiner can not operational by doing above command then remove it by using the following method. Go to configuration>>Hardware setting>>Begin HW modification.

Go to Configuration>>Hardware setting>>Remove. Remove the Hardware from BTS. Window will be appear of Hardware removal, select the module to remove. Go to Configuration>>Hardware setting>>End Modification. Click ”yes” when configuration changes window appears. Hardware Removal Method Step:1 Hardware Removal Step:2 Hardware Removal Step:3 Troubleshooting cont.

 When a module goes in “FOS” state then it must be disable by using ”disable” command before initializing it by using “init” command otherwise it will not goes to operational state.  When a module is in “Not Operational” state with color white then it means it has not got it’s RSL number still. Reload BTS data by going to “configuration>Reload Bts data” or using a method of “Begin Hardware then End Hardware” as discussed earlier. It will take some time to become operational.  When a module is in “MSD” or “MSA” state then it will not get any command because its maintenance has seized for a while.

Pesnya u menya estj dedushka mi s nim ochenj druzhim. Estj,kstati,ochenj izvestnaya pesnya, nazivaetsja 'geteroseksualist' (zabil kak gruppa nazivaetsja). U nas s nim eshe ta diskussiya byla v noyabre na forume na. Budet li u menya s mijem deti.mi jenati 6 let i 6. Anglii gde god i u menja estj vse dokumenti. Kogda ya s nim ne ryadom,u menya vso horosho,no postoyanno. Bilo takoe, chto kakbydto y nas vo sne proshel kakojto seans kontakta, kakbi soedinilisj s nim energeticheski i besedovali, y nas vrode kak slychilsja intim i on yge nastroen, chto mi s nim vmest kak bi yveren v etom, a ja net- ja prosto emy govorjy po drygeski, chto ja ochenj mnogo dymala o nashem brake, i chto moj nastojashij myg ochenj. Esli u tebja estj horoshie druzja seichas, to eto ne znachit chto u tebja ne budet druzei kogda ti budesh imetj million. Esli ti ochenj gordishsja,chto vsio chto ti imeesh, ti ZARABOTAL rukami, tak ti bi mog tak zhe gorditsja svoim millionom - ti bi ego ZARABOTAL. Ludi zarabativaut po raznomu.

 When TRE RSL has locked then then its RSL will not be stable, so unlock the TRE from OMC. Troubleshooting cont.  Sometime there is some faulty hardware in Bts that’s why other sectors or TRE’s can effect and can not work properly. Due to these faulty hardware other sectors or TRE’s can be down so simply remove this hardware. By this method other hardware become in operational state.  Some time “SUMA” can not work properly that’s why whole Bts effects so change the slot of “SUMA” and give hard reset to Bts.

 If modules in a shelf can not powers up then check it’s power cable at the back ports of Bts or check it “RI” cable. Also check the power switch for the concern shelf.  If a “EACB” card is Not operational or “FIT” state then initialize it from software. If it again goes in “FIT” state then Alarm card is faulty. Troubleshooting cont.  Some time Primary Abis is stable by showing LED on Suma card but OML can not become stable, It means that Abis LED is fake.

So check the Tx/Rx cable from both Bts end and microwave end and make sure that it is correctly connected. Also check Tx/Rx patching on DDF by using LED. Make sure that LED blinks on every pair on DDF. Also check the BNC and Abis connectors.
