Telecommunication & Computer Networking

Abstract

In addition to being a phone carrier and CC domain registrant, BTCL also manages the IGW, IIG, ICX, ISP, NGN, and PSTN (.BD). BTCL owns and operates the majority of the copper, fiber optic, and microwave networks in the country. The Post and Telegraph Division of BTCL was established in 1853. All of BTCL is currently owned by the government. One of the most important services provided by BTCL is landline phone service. There are a number of services available, including dial-up, high-bandwidth local and international leased lines, VPN, MPLS, and country domains (.bd). NGN will soon provide soft switch services and triple play on fiber at home. I wrote this article following a four-month internship at Bangladesh Telecommunications Company Limited. I was able to learn more about a telecoms company's everyday operations thanks to this internship program. The focus of this article is firmly on my personal views and academic knowledge.
