E-tds-fvu file upload

Dear All,

Once we file e-TDS using RPU provided by the TIN-NSDL, it will generate FVU file, which we are supposed to upload online with the help of NSDL franchisee, but i myself have one DSC issued by TCS(specified by the NSDL),  can anyone let me know whether I myself can upload the FVU file online by using that DSC, if so, plz tell me how to do that.

Thanks & Regards,
