ABSTRACT:
This invention relates to an interface for interfacing between two different types of networks, such as a GSM cellular radio network and an integrated services digital network (ISDN). The interface communicates between channels of one such network with channels of the other such network by mapping control information between the first (D) and second (Dm) control channels. In a first state of operation, the interface maps data between the first (B1, B2) and the second (Bm) data channels under the control of control information on the control channels. In a second state of operation, the interface maps data between the first control channel (D) and the second data channel (Bm) under the control of control information on the control channel.
