Protocol conversion apparatus and protocol conversion method

摘要

A control unit (100) sets up a path in a protocol conversion apparatus (30) based on call setting information from the calling side terminal. A signal monitor unit (300) monitors main data 220a transmitted in the path and sent/received between the terminals. When a specific connectivity confirmation sequence is detected by the signal monitor unit (300), the result is forwarded to the control unit (100). Based on the forwarded result, the control unit (100) specifies a protocol of the calling side terminal and a protocol of the called side terminal. A protocol conversion unit (310) performs the most suitable protocol conversion based on the specified protocols.
