How to scan AISG device in OMCB First of all you have to configure Antenna type as RET in SDR Negotiation file as shown below while creating site..

A. Scan in OMCB

1) Click on SDR Config Management and choose AISG Equipment Central Management.

2) A window will pop up, select the site and right click and select parallel scan.

3) It will show like below . click OK . and wait 10-30 minutes . YOU can not close this window and do any other operation during this period

4) After 10-30 minutes, if the site has AISG device and the AISG cable is connected properly. It will show like below.

5) So if your scan result is 0 device for 3G outdoor sector, please check the AISG cable connection, try to swap with working RET or check the model (KA 86010045 model not support) until it is OK. Rack 2 is RSU82 3G RSU and having 2 Antenna.

6) Note down the device ID and AISG version no and save it in your laptop as we have to configure this device ID and version in SDR MO file.

B. Configure in SDR MO data excel

1) Use CMX OMCB --- Modify data----Execute

2) Excel file will be opened.

You need refer your scan result when you do configuration.

Figure: Scan result

3) Go to index, and select RfCable and fill as below sample.

4) Only two column need to change.

5) Column L and Column M

6) For Rack 57, 58, 59, 60, move the content in Column L to Column M

7) In this sample. 57 have 1and 2 , 58 have 3 and 4 , 59 have 5 and 6

8) Go to index, and select AisgDevice and fill as below.

9) Column B-OMCB ID

10) Column C-Site ID

11) Column D:Rack No, input the Rack you scaned have AISG device.

12) Column E: No need to input

13) Column F: input the Device serial number refer to your scan result. Must be the same .

14) Column G: input the Mode refer to your scan result ---Device type .

15) Column H: input the Vendor Code refer to your scan result--- Vendor code. (if the version is 2.0, must input the Vendor code) you can give 1..

16) Column I:refer to your scan result--- AISG version

17) Column J: Fill in 255

18) Column K,L,M,O: blank

19) Column N: refer to the Column M(Connected RET Antenna RDN) of RfCable sheet above. Input the first one, like 1,3,5,7.

20) Example:

a. Rack 57 – Connected RET Device RDN 1

b. Rack 58 - Connected RET Device RDN 2

c. Rack 59 - Connected RET Device RDN 3

21)

After modification Save and close excel and upload to OMCB.

1) Check for the alarm

2) If have RET communication link broken or interrupted alarm. Please check your configuration. The data must be consistent with the result you scanned.

B. Check RET working status

3) Check RET configuration in Query Aisg Device

Result shown like below. Now select any device and right click and select set tilt to set the tilt on that device. If you want to set the tilt as 2 degree you have to give 20 as it is multiple of 0.1 as shown below.

If you want to check the tilt click on Get tilt.

D. FAQ

1) What is AISG?

a. AISG is “Antenna Interface Standards Group”, it is refer to RET & TMA. RET is connect to antenna mechanically & allow us to tune downtilt for antenna remotely.

2) What if no RET device found after scan?

a. If the result show blank after 10-30mins scan. Please follow below steps to troubleshoot.

i. Check in OMCB, is the RET already configured? If it already configure in OMCB. No result will show.

ii. Check the RET model is not Katherine 86010045, which is currently not support by ZTE SDR. The model number can be found at the label on RET. Sample is shown as below:

iii. Check for the cable connection in between RET & RRU. Typically we have 2 scenario as below:

1. If RRU>20m from antenna

Note: NSBT & ASBT is not RET. These 2 devices are just Smart Bias Tee to combine the AISG signal to feeder.

2. RRU <20m from antenna
