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.

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.
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. Abis cable which is connected from Suma card to Bts board can be faulty so also verify it.
If a TRE or combiner can not operational than change its slot then verify it.
Vswr issues can be resolved by checking connectors from Bts end and feeder end.
The last option for Alcatel equipment to become operational is the “Hard reset of Bts”.
