It was listed on the National Register of Historic Places in 1988. ==History== As the number of businesses in Washington increasingly relied in telephone service, Chesapeake and Potomac Telephone Company built this building as its new main exchange. Designed by architect Leon Eidlitz, it was the first of a complex of buildings the company would construct at this site. The building houses what was considered to be the largest telephone switchboard at the time. It began operations in September 1904 and served 6,000 at the beginning.〔 The new system eliminated the multiple rings on party lines and the need for an operator to interrupt the line to determine whether a subscriber had completed a call or wanted to receive calls. 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「Chesapeake and Potomac Telephone Company, Old Main Building」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
