Foreword This Technical Specification (TS) has been produced by ETSI Project Broadband Radio Access Networks (BRAN). The present document defines the functionality requir
29、ed for interworking HIgh PErformance Radio Local Area Network Type 2 (HIPERLAN/2) with IEEE 1394 6. Separate ETSI documents provide details on the system overview, data link control layer, radio link control sublayer, other convergence sublayers and conformance testing requirements for HIPERLAN/2. T
30、he present document is part 3 of a multi-part deliverable covering the Packet based Convergence Layer, as identified below: Part 1 : “Common Part“; Part 2: Part 3: Part 4: Part 5: “Ethernet Service Specific Convergence Sublayer (SSCS)“; “IEEE 1394 Service Specific Convergence Sublayer (SSCS)“; “IEEE
31、 1394 Bridge Specific Functions sub-layer for restricted topology“; “IEEE 1394 Bridge Specific Functions sub-layer for unrestricted topology“. Part 1 describes the functionality for adapting variable length packets/frames to the fixed size used in the Data Link Control (DLC) layer. Further parts, ea
32、ch defining a Service Specific Convergence Sublayer (SSCS), describe the functionality required to support a certain protocol, e.g. IEEE 1394 6 or Ethernet protocols. The SSCSs all use the services of the Common Part and the DLC 2. It is envisioned that several, independent, service specific parts w
33、ill be defiied in the future as market requirements develop. As a result, further parts may be added in the future. ETSI 8 ETSI TS 101 493-3 V1.2.1 (2001-12) 1 Scope The present document is applicable to HIPERLAN/2 equipment supporting interworking with 1394 buses. The present document only addresse
34、s the functionality required to transfer IEEE 1394 6 traffic over the radio interface between HIPERLAN/2 devices. It does not address the requirements and technical characteristics for wired network interfaces at a HIPERLAN/2 device. The present document uses the services provided by the Common Part
35、 of the Packet based Convergence Layer and by the Data Link Control layers of HIPERLAN/2. The present document does not address the requirements and technical characteristics for type approval and conformance testing. Those are covered in separate documents. 2 Re fe re nces The following documents c
