Abstract

Communication, for example, via the internet protocol (IP), is facilitated among ATM-attached, LAN-attached and telephone-network-attached hosts, by a so-called "RouTel" and an address server. The RouTel provides gateway capabilities for connecting a) the telephone network, e.g., via 1) integrated services digital network basic rate interface (ISDN BRI), 2) ISDN primary rate interface (ISDN PRI), or 3) modem interfaces, and b) an ATM network, via one or more ATM interfaces. Optionally, the RouTel provides interfaces for directly attaching legacy LANs, e.g., Ethernet, FDDI, and Token Ring. More particularly, the RouTel can perform IP packet forwarding between 1) a telephone-network-attached host and an ATM-attached host; 2) two telephone-network-attached hosts; and 3) a telephone-network-attached host and a legacy LAN-attached host.
