        <Description>
            <Section>The Protocol Stacks are used to define the functionality of the GSM protocols for interfaces. The GSM specifications are normative when used to describe the functionality of interfaces, but the stacks and the subdivision of protocol layers does not imply or restrict any implementation.</Section>
            <Section>The protocol stack for fax and data transmission consists of several entities. Each entity has one ore more service access points, over which the entity provides a service for the upper entity. The entity, which is described in this document, is coloured grey in the following figure :</Section>
            <Section>Figure 1-1: Architecture of the fax and data protocol stack</Section>
            <Section>The information units passed via the SAPs are called primitives and consists of an operation code and several parameters. See the Users Guide for details.</Section>
            <Section>The entities of the fax and data protocol stack are:</Section>
            <Section>1.1 RA - Rate Adaptation</Section>
            <Section>This entity performs an adaptation between an asynchronous or synchronous data stream with several bit rates on to the fixed bit rate used at the TCH. This is performed by the rate adaptation functions RA1' and RA0 described in GSM 04.21.</Section>
            <Section>1.2 RLP - Radio Link Protocol</Section>
            <Section>This entity provides a Layer 2 protocol for asynchronous reliable data transfer as specified in GSM 04.22. It includes error correction, sequence numbers and a mechanism for repeating corrupted and lost messages.</Section>
            <Section>1.3 L2R - Layer 2 Relay Functionality</Section>
            <Section>The L2R provides relay functions in order to adapt the character-oriented data received from the TE via USART to the bit-oriented RLP protocol.</Section>
            <Section>1.4 ACI - AT Command Interpreter</Section>
            <Section>The ACI is specified in GSM 07.07. It is responsible for call establishment via the GSM voice protocol stack and terminal adaptation for asynchronous transparent character-oriented data transmission. The ACI is able to receive AT commands and send the replies over the USART driver to a remote PC. This makes it possible to control the voice and data protocol stack from a remote application running on a PC. The ACI also provides a unique interface for an internal MMI in the MS.</Section>
            <Section>1.5 USART - Universal Synchronous Asynchronous Receiver Transmitter Driver</Section>
            <Section>The USART is a hardware component that facilitates a connection between the mobile station and terminal equipment (e.g. a PC). This interface uses some of the circuits described in V.24.</Section>
            <Section>The data exchange provided by this unit is serial and asynchronous (synchronous communication is not in the scope of this document). A driver that uses interrupts to manage a circular buffer for the sending and receiving direction is necessary in order to use this component in the F&amp;D. The driver has to be able to perform flow control.</Section>
