TAE (''Telekommunikations-Anschluss-Einheit'', i.e. telecommunications connection unit) is the German standard for telephone plugs and sockets. The standard covers two TAE types: F ("Fernsprechgerät": for telephones) and N ("Nebengerät" or "Nichtfernsprechgerät": for other devices such as answering machines and modems). U coded sockets and plugs are universal connectors that are suitable for both device types. E-coded connectors that are used in EAD-sockets are not intended for telephony applications. ==History== The TAE system was introduced in the late 1980s before the German government-owned institution Deutsche Bundespost (DBP, German Federal Post) was divided into Deutsche Post (postal service), Deutsche Telekom (telecommunication services) and Postbank (financial services). Previously, the older ADo type connectors had been used, or telephones had been hardwired to their (VDo) wall sockets, and only officially approved telephones (legally distributable only by the DBP) were allowed to be connected to the telephone system. Furthermore, telephones and other communication devices could only be leased from the DBP and not be sold or bought on the free market. The introduction of the TAE system was the practical enabling technology of the legal specification in Germany that communication terminal equipment should be in the responsibility of end users. Subsequently, many communication devices became available in the open market that could be plugged into standard TAE sockets. Adaptors allow for connecting devices with registered jacks that are more prevalent internationally. Today, TAE connectors are common in Germany and other central European countries like Liechtenstein and Luxembourg. Modern TAE sockets also contain circuits referred to as ''passiver Prüfabschluss'', meaning ''passive test connection''. This provides a discernible condition to the telephone exchange indicating that the line is continuous to the TAE-connected device. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TAE connector」の詳細全文を読む スポンサード リンク
