Abstract
The present invention provides an ATM switch which includes: memory for storing identification information which identifies user-network interfaces with terminals, analysis control data for analyzing a call control signal for each user-network interface, and editing control data for editing a call control signal for each user-network interface; analysis circuit for analyzing a first call control signal in accordance with the analysis control data corresponding to a first user-network interface identified on the basis of the identification information when the first call control signal is received from a first terminal for setup with a second terminal; call control circuit for performing call control based on the first call control signal analyzed by the analysis circuit; and editing circuit for editing the first call control signal to a second call control signal in accordance with the editing control data corresponding to a second user-network interface identified on the basis of the identification information. Preferably, ATM switch further includes interworking control circuit for controlling call process when an error is detected while the second call control signal is being edited.
