7 <Description>
8 <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>
9 <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>
10 <Section>Figure 1-1: Architecture of the fax and data protocol stack</Section>
11 <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>
12 <Section>The entities of the fax and data protocol stack are:</Section>
13 <Section>1.1 RA - Rate Adaptation</Section>
14 <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>
15 <Section>1.2 RLP - Radio Link Protocol</Section>
16 <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>
17 <Section>1.3 L2R - Layer 2 Relay Functionality</Section>
18 <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>
19 <Section>1.4 FAD 03.45 - Fax Adaptation Protocol</Section>
20 <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>
21 <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>
22 <Section>1.5 T.30 - Fax Protocol Entity</Section>
23 <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>
24 <Section>* Building the HDLC frames with CRC.</Section>
25 <Section>* Performing bit stuffing/de-stuffing.</Section>
26 <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>
27 <Section>1.6 ACI - AT Command Interpreter</Section>
28 <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>
29 <Section>1.7 USART - Universal Synchronous Asynchronous Receiver Transmitter Driver</Section>
30 <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>
31 <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>

681 <Primitive>
682 <Description>
683 <Section>The L2R_ACTIVATE_REQ is used to initialise the L2R entity. This is the first primitive, which should be passed to L2R after starting the entity. It contains all parameters necessary for initialisation. Those parameters, which belong to the RLP layer are just passed on to the RLP entity. The remaining parameters are related to the data compression, which is a part of the L2R layer. These parameters are passed to the RLP entity as well, because the negotiation of these parameters with the base station is done by the RLP entity. The negotiated parameters are returned to the L2R entity by a RLP_XID_IND.</Section>
684 <Section>L2R in turn passes these Parameters to the upper layer in a L2R_XID_IND. After sending a L2R_ACTIVATE_REQ the upper layer should wait for the L2R_XID_IND, before sending a L2R_CONNECT_REQ, because the negotiation of data compression parameters is only allowed in the disconnected state. It is not required to guard the reception of L2R_XID_IND by a timeout, since the RLP entity has a timeout, which would generate an error indication in case of failure.</Section>
