1. A method comprising:
- transmitting an unsolicited message from a central server in an Asynchronous Transfer Mode (ATM) network to a selected one of a plurality of ATM endpoints connected to the central server via respective virtual circuits, the unsolicited message including an Internet Protocol (IP) address for the central server and an IP address for the selected ATM endpoint;
receiving the unsolicited message at the selected ATM endpoint;
extracting the central server IP address and the ATM endpoint IP address from the unsolicited message; and
transmitting an Simple Network Management Protocol (SNMP) TRAP message to the central server indicating that the ATM endpoint is operational as a result of receiving the central server IP address and the ATM endpoint IP address.

Abstract
In an ATM network having ATM endpoints connected to a central server over respective virtual circuits, ATM endpoints are configured for Internet Protocol (IP) over ATM communications by transmitting an unsolicited message from the server to the selected ATM endpoint at a first transmission interval over the associated virtual circuit, the unsolicited message including a server IP address and an ATM endpoint IP address; and receiving the unsolicited message at the selected ATM endpoint, including extracting the server IP address and the ATM endpoint IP address from the unsolicited message and transmitting an SNMP TRAP message to the server.
