What does telecom sp service mean?

SP, abbreviation of Service Provider \x0d\ What is telecom value-added service \ x0d \ x0d \ Telecom value-added service refers to the additional communication service developed by using the resources of public telecommunication network and other communication equipment, and its realized value increases the economic benefit or functional value of the original network. Sometimes called enhanced services. \ x0d \ x0d \ value-added services can be roughly divided into two categories: one is the service in the form of value-added network (VAN). Value-added network can make use of special equipment such as switches and computers in this department to form a private network with transmission equipment rented from public network to meet the needs of this department. For example, a fax store-and-forward network composed of leased high-speed channels, a conference television network, a private packet switching network, a virtual private network (VPN), etc. The second is the business in the form of value-added services. Refers to the services developed beyond the basic services of the original communication network (telephone and telegraph services), such as database retrieval, data processing, electronic data exchange, e-mail, electronic directory search and electronic file transmission. \ x0d \ x0d \ At present, the main value-added services opened on China's telecom network are: \ x0d \ x0d \ (1) e-mail, also known as e-mail. The latest generation of e-mail box is message processing system (MHS), which can realize the interoperability between heterogeneous computers.

In order to meet the needs of domestic users, the Ministry of Posts and Telecommunications takes Beijing, Shanghai and Guangzhou as national import and export bureaus and connects with the Internet in the United States.
