| 单词 | KTS (Key Telephone System) |
| 释义 | KTS (Key Telephone System) A voice-optimized telecommunications system designed for small business or small office applications (see Figure K-1), typically defined as involving no more than 50 stations.The term key refers to the buttons that mechanically opened and closed the line circuits on the early generation of KTSs. Although the buttons are no longer mechanical keys, KTSs remain relatively simple CPE systems that allow multiple station users to share a number of outside lines that the users select by depressing the button associated with the specific circuits they desire to access.This approach is unlike that of a PBX switch, which has the intelligence to accept a call request from a user station, determine the most appropriate circuit from a shared pool of circuits, and set up the connection through common switching equipment.
