Data Check Audit

Process to identify possible issues, in case desired speed is not achieved:

1. Check speed through NetPerSec tool

2. Cross-check HSDPA related parameters in RNC & Node B

3. Check SGSN Profile

4. Check HLR Profile (user profile)

5. Check for Time Delay & Jitter using Ping Plotter tool

STEPS FTP PROCEDURE

Step1 Connect to internet using APN httpnorth.cellone.in

Step2 Disable firewall on your system as it wont allow you to access the server.

Step3 In run window type cmd and come to command window.

Step4 type cd\ and then enter which will bring you in c drive(C:\>)

Step5 Now type ftp 10.147.4.10

Step6 username-test1 and password-test1

Step7 type dir (this will show you all files in the server)

Step8 Type hash and the enter

Step9 To download any file type: get <filename> and then press enter

Step10 Download will start,at the end of which you will see the average speed.
