Abstract:
BTCL handles the PSTN, IGW, IIG, ICX, ISP, NGN, and is a CC Domain Registrar in addition to being a voice carrier (.BD). Nearly all of the copper, fiber optic, and microwave networks in the country are owned and run by BTCL. In 1853, the BTCL's Post and Telegraph Division was established. As of right present, the government owns all of BTCL. Landline telephone service is one of the most vital services provided by BTCL. There are many services offered, including dial-up, ADSL, high-bandwidth local and international leased lines, VPN, MPLS, country domain (.bd), co-location, and others. Soft switch services and triple play on fiber at home will soon be offered by NGN. After finishing a four-month internship at Bangladesh Telecommunications Company Limited, I wrote this essay. Through this internship program, I was able to get knowledge about a telecoms company's daily operations. This article places a strong emphasis on my observations and professional expertise.
