PURPOSE: An ACR(Automatic Call Routing) terminal for sensing the status of a hook and automatically transmitting input number of pre/post-paid card is provided to support the convenience to a user by sensing the off-hook status when the user picks up the phone and when the user uses a pre/post-paid card, by automatically transmitting the relevant numbers of the card which were needed to be pressed one by one by the user. CONSTITUTION: An automatic call routing terminal is connected to a telephone and detecting data input from the phone to have an automatic calling line function. In the ACR router, a memory means receives the relevant number of the telephone and program-related data. A programming means sets the data stored in the memory means to suit for the process of telephone card switching network. A hook status sensing means senses the status of the hook when a user picks up the handset. An automatic transmitting means automatically transmits the relevant telephone number set when off-hook to the telephone card switch network. A voice sensing means senses the output voice of the telephone card switching network and effectively treats it. If the telephone card switch network has a blocking, busy or call-unavailable message, an automatic by-pass means transfers it to office line.
