NMS SCCP consists of a set of functions that provide access to the SCCP layer operations, and a set of events that notify the application of incoming messages, network status, and message delivery errors. NMS SCCP also performs the byte ordering translation, where necessary, between application processor (little endian) byte order and network (big endian) byte order.
NMS SCCP is implemented as a Natural Access service. Natural Access is a development environment for telephony and signaling applications that provides a standard application programming interface for services, such as signaling protocol stacks, independent of the underlying hardware. Understanding the basic Natural Access programming concepts such as services, queues, contexts, and asynchronous events is critical to developing applications that use the SCCP service. Refer to the Natural Access Developer's Reference Manual for more information.
