Detailed Solution

The full form of STD is Subscriber Trunk Dialling.
One of Asia's most extensive telecom networks is found in India. Over two-thirds of Indian villages and metropolitan areas currently have Subscriber Trunk Dialling (STD) telephone service. It is also referred to as subscriber toll dialling. Subscriber trunk dialling (STD) incorporates a telephone numbering plan feature and telecommunications technology allowing telephone subscribers to place trunk calls on their own without the intervention of switchboard operators. The government has made specific provisions to extend a twenty-four-hour STD facility to every hamlet in the nation to improve the flow of information from lower to higher levels. In India, the prevalence of STD facilities is uniform across the country. It has been made possible by fusing in both communication and satellite technology advancements.
