Abstract

PURPOSE:To attain the reception of an emergency telephone call by allowing a personal computer to interrupt data communication processed at present in receiving an interrupt from a catch phone service signal identification device to accept an opposite party coming newly and to restart the preceding data communication interrupted before after the end of the new call. CONSTITUTION:A catch phone service signal identification device 4 recognizes an interruption tone generated and sent by the catch phone service function of an exchange 3 and gives interruption to a personal computer 11 during data communication when the interruption tone comes. The personal computer 11 discriminates the entrance of interrupt to the personal computer communication executed at present, hooks on the line to reply the interrupting line without disconnecting the line making data communication so far. When a personal computer communication request or emergency telephone call comes from other party while the terminal equipment is in the personal computer communication, it is possible to receive the external call.
