BSNL JTO Syllabus For Electrical Engg

My brother has completed B.E Degree with Electrical Engineering from Anna University. Now he wants to appear in BSNL JTO Exam. So can you please give full syllabus for Electrical Engineering Branch? What are minimum marks required to crack the BSNL JTO Examination? Give me its last years question paper also.

Can you provide me the Syllabus for preparation of BSNL JTO (Bharat Sanchar Nigam Limited Junior Telecom Officer) (Electrical) Post recruitment examination?
