Abstract:
BTCL is a voice carrier, IGW, IIG, ICX, ISP, NGN, and PSTN operator, as well as a CC
Domain Registrar (.BD). BTCL owns and operates almost all of the country's copper, fiber optic,
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 most essential services offered
by BTCL is landline telephone service. Dial-up, ADSL, high-bandwidth local and international
leased lines, VPN, MPLS, country domain (.bd), co-location, and other services are all available.
NGN will soon provide soft switch services as well as triple play on fiber at home.
I wrote this paper after completing a four-month internship at Bangladesh Telecommunications
Company Limited. This internship program provided me with the ability to learn about the dayto-day activities of a telecommunications company. The emphasis of this article is on my
observations and company experience.
