NSN_Flexi_Hybrid_IDU

Dear all,

NSN flexi hybrid IDU (SRA4_HC) is a transmission equipment developed by NSN. My questions are as follows:-

1) How to download the the IMG files using FTP client, using it there i got an error “Incorrent command”, so wht is the procedure for compying the IMG files to PC and vice versa for updating the FPGA

2) Normal NSN HOPPER has the power limit of -4 – 20 dBm but here the power limit is variable for diff diff IDUs i found e.g – 5-17 dBm or 5-20 dBm. Why? and if we can change the limit?

3) Always getting problem when commissioning it in East-West mode: assume that an IDU is already working with it’s East modem and now i have to put another link from it so i have connect the IF to west modem but when i connect it to west modem it takes much more time to detect the ODU and i got many parameter errors when commissioning, so wht’s the problem and wht would be the better way to commission in this situation.

4) When i connect the ODU (using IF) to IDU then the modem’s Status LED goes UP, if there is any way to lit off like previous if i disconnect it from ODU?

5) ODU getting faulty in general, what would be the real causes, whereas in same environmental & installation condition Hopper is more sustainable and getting 2% faulty in comparison.

thanx
