signaling packet

This is generated by an ATM-connected device that wants to establish a connection with another such device. The signaling packet contains the ATM network service access point (NSAP) address of the desired Asynchronous Transfer Mode (ATM) endpoint, as well as any QoS parameters required for the connection. If the endpoint can support the desired QoS, it responds with an accept message, and the connection is opened. See also QoS.
