Abstract:
To complete the BSc undergraduate program, we need to do a minimum of three months of internship from any reputed institute to complete the internship work successfully. My internship is a four (04) month program. During these four months, I have gained valuable experience and knowledge of my life. I am fortunate that I could intern at Bangladesh Telecommunications Company Ltd. (BTCL). This internship has tried to highlight the structure and design of Bangladesh Telecommunications Company Ltd. (BTCL). Phase 1 and Phase 2 internship programs of these two courses have helped me learn about telecommunication companies. Bangladesh Telecommunications Company Ltd. (BTCL) provides essential telecommunication services in our country. BTCL is a voice carrier, IGW, IIG, ICX, ISP, NGN, and PSTN operator, as well as a CC Domain Registrar (.BD) and (. Bangla). BTCL owns and operates almost all of the country's copper, optical fiber, and microwave networks. The Post and Telegraph Division of BTCL was established in 1853. BTCL is now a wholly-owned government subsidiary. One of the essential services offered by BTCL is the landline telephone service. Dial-up, ADSL and GPON, high-bandwidth local and international leased lines, VPN, MPLS, country domain (.bd) and (. Bangla), co-location, and other services are all available. NGN will soon provide soft switch services and triple play on fiber at home.
