        <Description>
            <Section>The Service Access Point (SAP) for an entity defines the interface supported by that entity in order to gain access to its services. This document contains a specification of the DL SAP for the Data Link layer (DL) entity of the Texas Instruments UMTS Dual mode protocol stack.</Section>
            <Section>The DL SAP is based on the exchange of primitives between the DL entity and the RR entity (see Figure 1).</Section>
            <Section>Figure 1: The DL SAP context.</Section>
            <Section>The 3GPP DL specification, [3G 04.06], defines primitives for the DL entity. These primitives are defined in an abstract manner that does not specify or constrain implementations. The primitives and parameters defined in the present document may deviate from the ones in the 3GPP specifications, although the general principle is maintained.</Section>
            <Section>Further information on the system design can be found in "Dual Mode System Design" [TI 8010.944].</Section>
            <Section>1.1 Reading Guide</Section>
            <Section>This document has three primary sections. The first (section 2) contains a specification of constants used on the interface, which are not specific to the value of a particular parameter. Such constants are typically size fields, specifying array or element sizes.</Section>
            <Section>The second primary section (section 0) contains the top-level description of the primitives defined for the interface. For each primitive its function is described, and a parameter list is given.</Section>
            <Section>For any primitive using complex structures or parameters with identified values, references will be given to subsections of the third primary section (section 4). This section contains specifications of the complex types used in the primitives of the interface. It also contains specifications of parameters with predefined values or value ranges. Cross-references to subtypes may be used within this section for complex type declarations.</Section>
            <Section>Types and constants, in this document, which are common for more entities and SAP's are imported via the common include-strategy. The common types and constants are imported from the common SAP documents specifying the interfaces throughout the protocol stack using the include mechanisms of the SAP tool-chain.</Section>
            <Section>The method used for exchange of primitives is message passing. The terms "message" and "primitive" are used interchangeably in this document.</Section>
            <Section>All constants will be prefixed by the value defined in the Pragma table in section 2. This is done by the SAP-compiler when compiling this file. That is, all constant values will have the prefix DL_.</Section>
            <Section>When primitives contain arrays of elements where the array size is not fixed, dynamic array declarations are used. This is indicated through the use of array element sizes of the form [MIN..MAX], where MIN denotes the minimum and MAX the maximum number of array elements used on the interface. Where such dynamic array elements are used, a length specifier is always implicitly present, giving the number of elements actually included in the primitive. This parameter is always named as the array parameter with an addition of the prefix "c_" (for count).</Section>
            <Section>In some primitives or structures parameters may be optional, depending on the actual context in which the primitive is used. In such cases mandatory and optional parameters are indicated for the entire primitive or structure. Wherever an optional parameter is present, a parameter will always implicitly be present, indicating whether the parameter is included in the primitive or not. This parameter is always named as the optional parameter with an addition of the prefix "v_" (for valid).</Section>
            <Section>In some primitives or structures the parameters may contain a pointer, which points to a structure or an array of structures, etc. This is indicated with a "PTR" inside the Ctrl column.</Section>
            <Section>For all primitives included in this SAP, it is an unavoidable fact that as the world of 3G evolves, some changes to this interface may be necessary. However, as this document is the basis for the DL SAP it will be fully maintained and all necessary changes will result in updated versions of this document.</Section>

                <Section>The sdu parameter contains the layer 3 message with L2 short header format. This is for SACCH channel type and a value of sapi set to 0 only. DL expects a sdu with offset 16 and a maximal length of 21 octects. The first two octets are place holders for the layer 1 header. From the third octect (offset 16) the sdu have to contain the layer 3 message according to the format type Bter. Bit 1 and 2 of the third octect should contain the short L2 header.</Section>

It consists of a length field specifying the size of the message in the container, an offset specifying where inside the included data array the message starts and a data array holding the message. The array has a default size of one byte, but in reality this is a variable length structure. Only use as the last element in a primitive, and allocate memory using SDU allocation routine.</Section>
