Internetworking telephony, IP and ATM networks
ITS'98 Proceedings. SBT/IEEE International Telecommunications Symposium (Cat. No.98EX202), 1999 This paper proposes a general internetworking principle applicable to internetworking any two networks. We apply this principle to the specific problem of internetworking ATM networks with the PSTN and IP networks. A proof-of-concept prototype implementation of the IP-ATM internetworking solution is also described.
