        <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 FAD 03.45 - Fax Adaptation Protocol</Section>
            <Section>The fax adaptation protocol, as specified in GSM 03.45, provides synchronisation with the BCS and MSG modems of the peer entity. It uses byte repetition in conjunction with a voting algorithm to handle corruption on the TCH data stream. The non-transparent fax protocol in accordance with GSM 03.46 is not part of this implementation.</Section>
            <Section>The fax adapter enables T.30 to send BCS at 300 BPS and T.4 MSG in 2400, 4800, 7200 and 9600 BPS.</Section>
            <Section>1.5 T.30 - Fax Protocol Entity</Section>
            <Section>The protocol uses binary coded signals packed in HDLC frames to set up and release a connection in the message phase of the FAX transmission. This entity is specified in the ITU-T.30. The main tasks of this unit are:</Section>
            <Section>? Building the HDLC frames with CRC.</Section>
            <Section>? Performing bit stuffing/de-stuffing.</Section>
            <Section>? Executing a sequence of 5 phases: 1.) set up, 2.) pre-message procedures, 3.) transmission/reception, 4.) post message procedures, 5.) waiting for call release.</Section>
            <Section>1.6 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>1.7 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>

            <Description>
                <Section>The ACI_CMD_REQ is used to pass a AT command to ACI. The command is defined as a string (defined in GSM 07.07/07.05). The attention prefix AT must be included in this primitive. In case of reading command sequences from a serial interface an ACI_CMD_REQ should only be generated for a complete input line which is terminated with e.g. CR/LF. The line termination characters should not be included in the command parameter.</Section>
                <Section>Every ACI_CMD_REQ must be acknowledged with a ACI_CMD_CNF by the ACI. After sending an ACI_CMD_REQ the MMI must wait for the corresponding ACI_CMD_CNF, before another ACI_CMD_REQ can be sent.</Section>
                <Section>For further studies:</Section>
                <Section>In a future implementation the AT command can be coded binary as an option.</Section>

                <Section>The ACI_ABORT_REQ should be used to abort the execution of the last send ACI_CMD_REQ primitive. If the last AT sequence is already processed this primitive will be discarded by the ACI. ACI does not send any result of the aborted command, but acknowledges the ACI_ABORT_REQ with an ACI_ABORT_CNF. All unsolicited results which will be received by the user of the SAP before the ACI_ABORT_CNF must be discarded. They are not acknowledged by an ACI_CMD_RES.</Section>

                <Section>The parameter identifies the initiator's location of ACI_CMD_REQ. Possible location are an internal or an external application. Normally the application like an MMI runs on the same microprocessor like the protocol stack. In this case the application must set this parameter to CMD_SRC_INT. Command sequences which are received via the serial interface are converted into ACI_CMD_REQ primitives and were send via IPC mechanism from the serial driver software to the ACI entity. In this case the driver will send this parameter to CMD_SRC_EXT.</Section>

                <Section>If the command parameter is used in a ACI_CMD_REQ primitive it contains a non-empty sequence of AT commands. The command sequence contains a leading "AT" but not a trailing line termination e.g. CR/LF. The processing of each command may lead to one ore more ACI_CMD_IND primitives and to a final ACI_CMD_CNF. The AT commands should be separated as described in GSM07.05. If the command parameter is used in a ACI_CMD_IND or ACI_CMD_CNF primitive it contains the results of the ACI like requested parameters or state indications.</Section>
                <Section>For further study:</Section>
                <Section>In an future implementation the command/response sequence can be defined in a compressed format to reduce the ROM space. Therefore, each command and response will have a unique numeric representation. The numeric format makes it possible to implement a quick command scheduler which uses e.g. a switch statement to recognise the command. The binary format has not been defined yet. A list of constants which denote AT commands and their according values can be found in the values section of the cmd_seq parameter. NOTE: The numeric values which are defined at the moment may vary in the future. Always the symbolic constant should be used.</Section>
