Introduction.

The Application Layer consists of four main elements as shown in Figure 1-1. The Application Process is the interface to the Application Layer. Services are provided by the Common Application Language (CAL) Element to the User Element of the Application Process. CAL is the language framework through which Resource Allocation and Control functions are executed. Services are provided by the Message Transfer Element to the CAL Element. The Message Transfer Element interfaces to the Network Layer either directly or through the Association Control Element.

This document is arranged so that all services provided by the various Application Service Elements (ASEs) are described first. Following the description of the services is the specification of the Application Layer Protocol Data Units (APDUs). The document concludes with a specification of the protocol for each ASE.
