| 摘要 |
A package for performing mutual conversion between a first signaling signal and a second signaling signal, including a first signaling signal converting unit for outputting mutually converted first and second signaling signals and outputting a current state information based on preceding state information and current first and second signaling signals; a second signaling state holding unit for holding the current state information up to the next frame; and a timer unit for detecting that a current state information matching with the predetermined state information appears and outputting a time-out signal after an elapse of a predetermined time. Further, this package is included to realize a time-division multiplexer. By this, in a speech handling network in which exchanges of different kinds of signaling signal systems are mixed, the mixing thereof is easily and simply enabled by an introduction of the package equipped with the signaling signal conversion facility.
