1. An ATM network control apparatus comprising:
- first connection means for connecting to a first communication apparatus by using an interface according to a first method;
second connection means for connecting to a second communication apparatus by using an interface according to a second method which is different from the first method;
first conversion means for converting data received via said first connection means into an ATM packet;
second conversion means for converting data received via said second connection means into an ATM packet;
storage means for storing a table of header information for at least one communication network;
changing means for changing header information of the ATM packet converted by said first conversion means or said second conversion means on the basis of information obtained by referring to the header information of the ATM packet and the table stored in said storage means; and
output means for outputting the ATM packet having header information changed by said changing means to a corresponding communication network.

Abstract
An asynchronous transfer mode (ATM) network control apparatus receives data, converts the data into an ATM packet, stores a table of header information for at least one communication network, changes the header of the received ATM packet on the basis of information in the ATM packet header and the stored table, and outputs the modified ATM packet. Units which perform these functions are connected to a general purpose bus line and a high-speed bus line.

13. An ATM network control apparatus connectable to an ATM switching apparatus, comprising:
-
first network end means for communicating with a first communication network having a first communication method; second network end means for communicating with a second communication network having a second communication method different than the first communication method; and transmission means, shared by said first and second network end means, for assembling transmitted data from the first and second communication networks received by said first and second network end means according to the first and second communication methods, respectively, into an ATM packet and transmitting the ATM packet to the ATM switching apparatus, wherein each of said first and second network end means includes; first determination means for determining whether or not a destination of data sent from one of the first and second communication networks, which is connected to the network end means, is for the other of the first and second communication networks or for an ATM network; and first output means for sending the data to said transmission means when said first determination means determines that the destination of the data is the other communication network or the ATM network. - View Dependent Claims (14, 15, 16, 17, 18)

19. A control method for controlling an ATM network control apparatus connectable to an ATM switching apparatus and first and second communication networks via first network end means for communicating with the first communication network having a first communication method and second network end means for communicating with the second communication network having a second communication method different than the first communication method, said method comprising:
-
a first determining step, performed by the first and second network end means, of determining whether or not a destination of data sent from one of the first and second communication networks is for the other of the first and second communication networks or for an ATM network; a first output step, performed by the first and second network end means, of sending the data to outside of the network which sent the data when it is determined that the destination of the data is for the other communication network or for the ATM network; and a transmission step of assembling the data transmitted from the first and second communication networks received by the first and second network end means according to the first and second communication methods, respectively, into an ATM packet and transmitting the ATM packet to the ATM switching apparatus. - View Dependent Claims (20, 21, 22, 23)
