ABSTRACT:
A method for preventing false starts during a handshake session involves the use of service identifiers for modem devices. The identifications are provided to one another for subsequent communication. To commence communications, a local device generates a request signal to initiate a handshake session. The request signal includes an identification unique to the remote device. The remote device receives the request and verifies the identification. The remote device then sends a response, which may optionally include an identification unique to the local device. The local device receives the response and verifies the identification before completing the handshake session.
