本发明的目的在于提供用户交换机系统、用户交换机以及用户交换机系统的通信方法。用户交换机系统是包含划分为内线分组的多个内线电话机和向主叫方发送关于内线分组的信息的用户交换机的系统。连接用户交换机与内线电话的多个内线接口划分为分组。用户交换机呼叫对应于呼叫信号的内线分组的全部内线接口上连接的内线电话。在用户交换机中，存储部存储与内线分组有关的文字信息。控制部根据呼叫信号将与呼叫信号对应的内线分组的文字信息发送到主叫方的内线电话。借助于此，在主叫方的内线电话或外线电话的显示部显示上述信息。 A private branch exchange (PBX) system (100) includes plural extension telephones (114,115,116) divided into extension groups, and a PBX which sends information about one of the extension group to a caller. Plural extension interfaces (l/Fs) (101-104) coupling the extension telephones to the PBX are divided into groups. The PBX calls each of the extension telephones coupled to all the extension I/Fs of the extension groups corresponding to a call-in signal. In the PBX, a memory (108) stores text data about the extension groups. A controller sends the text data about the extension group to a caller's telephone responsive to the call-in signal. The information can be thus displayed on an extension telephone or an outside-line telephone (119) of the caller.
