Hello every one,
I would like to share the steps with photos to check the configuration of cells arrangement in BTS, it is important to be familiar with the order of the sub-racks cells to be able to know the arrangement of sectors, It is also important to be able to know that a cell contains one or more RF units, sometimes one cell works on more than one band such as (UMTS<E) or (UMTS&GSM), I will explain all this in this article.
Steps to check sector configuration
Query All RF units
1- To query all RF units that defined in the configuration, use the command LST RRU
Standard Feeder Labels
We use the standard label color for the ranking sector
A- Red color for sector one.
B- Yellow color for sector two.
C- Blue color for sector two.
So I used the same colors to show the arrangement of the cells in the following image,
Sector 1 sub-rack 80, 81 sector works UMTS & LTE RF unit type RRU.
Sector 2 sub-rack 82, 83 sector works UMTS & LTE RF unit type RRU.
Sector 3 sub-rack 84, 85 sector works UMTS & LTE RF unit type RRU.
Sector one (1-4-1) means cabinet 1 sub-rack 4 slot 1 sector works U900 RF unit type MRFU
Sector one (1-4-2) means cabinet 1 sub-rack 4 slot 2 sector works GSM RF unit type MRFU define on GTMU
Sector two (1-4-3) means sub-rack 4 slot 3 sector works U900 unit type MRFU
Sector two (1-4-4) means cabinet 1 sub-rack 4 slot 2 sector works GSM RF unit type MRFU define on GTMU
Sector three (1-4-5) means sub-rack 4 slot 5 sector works U900 unit type MRFU
Sector three (1-4-6) means cabinet 1 sub-rack 4 slot 2 sector works GSM RF unit type MRFU define on GTMU.
This site contains three sectors for band 900 & 2100, each sector has two RF units.
Query All Sectors
2- To query all sectors that defined in the configuration, use the command LST SECTOR.
This command gives the same result but with sectors, the site contains three sectors for band 900 & 2100.
Query Sectors Configuration
3- If you want to view more details about the composition of cells, you should use LST SECTOREQM
With this command, you will get all TX & RX sector configuration.
You can execute this command first without filling in the sector equipment id to get the sector equipment id for all sectors.
Sectors Configuration Details
Sector 1 RRU (UMTS & LTE)
After filling the sector equipment if you will get the TX and RX configuration of the sector
the result of the following image shows us that the first sector band 2100 takes sub-rack 80,81 and active ports in each RRU (ROA) and each port is running RX & TX.
Sector 2 RRU (UMTS & LTE)
The result of the following image shows us that the second sector band 2100 takes sub-rack 82,83 and active ports in each RRU (ROA) and each port is running RX & TX.
Sector 3 RRU (UMTS & LTE)
The result of the following image shows us that the third sector band 2100 takes subrack 84,85 and active ports in each RRU (ROA) and each port is running RX & TX.
Sector 1 MRFU (U900 & GSM)
The result of the following image shows us that the first sector band U900 takes cabinet 1 subrack 4, solt 1 and active ports in MRFU (ROA) and running RX & TX and (ROB) running RX.
Sector 2 MRFU (U900 & GSM)
The result of the following image shows us that the second sector band U900 takes cabinet 1 subrack 4, solt 1 and active ports in MRFU (ROA) and running RX & TX and (ROB) running RX.
Sector 3 MRFU (U900 & GSM)
The result of the following image shows us that the third sector band U900 takes cabinet 1 subrack 4, solt 1 and active ports in MRFU (ROA) and running RX & TX and (ROB) running RX.
Best Regards,
