1 Scope
This European Telecommunication Standard (ETS) specifies a function that allows data communication
applications utilizing protocol stacks which include High Level Data Link Control (HDLC) procedures
(ITU-T Recommendation X.25, [2]) also to be deployed in a Broadband Integrated Services Digital
Network (B-ISDN) environment.
The required mapping function specified in this ETS is called "Service Specific Convergence Sublayer for
HDLC Applications".
This ETS makes use of the fact that the functionality of the HDLC framing, i.e., the flag and abort
sequences, the zero-bit insertion, and the Frame Checking Sequence (FCS) can be interpreted as a
subset of the services offered by the ATM Adaptation Layer type 5 (AAL 5) as specified in
ITU-T Recommendation I.363.5 [1].
This ETS is applicable to equipment to be attached to a B-ISDN network when protocol stacks developed
for an HDLC-based environment are to be deployed.
2 Normative references
This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.
