NOTE Some references in this standard reflect the fact that the text was initially produced in CEPT working

10、groups. For practical reasons it has not always been possible to re-edit the text appropriately at this strige. 1. General 1.1 Introduction 1.1.1 This standard specifies the basic requirements concerning the layer 3 basic call control protocol which Terminal Equipment (TE) has to meet for attachment

11、 to the public ISDN basic user - network interface at the S/T reference points. The requiremenls sppcified in this standard are in addition to those relating to the layer 1 and 2 aspects given in NET 3, Part 1. This standard does not cover all the requirements which a specific type of TE has to meet

12、. However, standards/NETs which define attachment requirements relevant to a specific type of TE should reft-c to this standard for the attachment requirements within th43 mope of this standard. 1.1.2 Unless otherwise stated, the use of the term TE within this specification refers to c:ustomers term

13、inal apparatus which may be a TE (Terminal Equipment Type i), a TA (Terminal Adaptor) or an NT2 (Network Termination Type 2) as defined in CCITT Recommendation X.411 141. 1.1.3 Communication between adjacent layers (primitive procedures) is conceptual and allows the description of interactions betwe

14、en functions dedicated to different layers within a TE. These primitive procedures do not constrain implementation, are system internal and therefore cannot be tested in isolation. However, as seen from outside, the design of TE shall be such that the strquence of events across the user - network in

15、terface must be the 8-e as if the primitives were implemented as described in ETS CA (TC doc. No. T/S 46-30) 2 and ET6 CB (TC doc. No. T/S 46-31) 3. 1.2 Cmfisurations at User Prtmiaes.
