5 3. GENERAL ASPECTS 3.1 Scope This FIS is applicable to radio communication systems providing communication services for safety-related application processes using open networks. It specifies the ERTMS Level 1 message exchange between on-board equipment and Radio In-fill unit Radio In-fill shall use services and protocols as specified by UNISIG EURORADIO FIS and UNISIG Key Management System This FIS is strictly dependent on the UNISIG EURORADIO FIS [5], specifying the Radio System Interoperability for message exchange between on-board and trackside equipment in respect to safety-related application processes, like Automatic Train Control of ETCS level 2/ For this reason this document has the same structure of [5]. Each chapter of this FIS contains only the reference to EURORADIO FIS and the possible specific characteristics (differences) for in-fill application Some features shall be optional for Radio In-fill application This FIS does not define: a) the radio in-fill application functionality and application information flow. b) the open networks used. c) the physical architecture of the radio communication subsystem Within the scope of this document the terms Radio Communication System (RCS) and EURORADIO system are used synonymously. 3.2 Acronyms and abbreviations See [5]. 3.3 Definitions See [5].

7 4. REFERENCE ARCHITECTURE See [5] The following features and options shall not be required for ETCS level 1 radio in-fill: a) exchange of non-safety related information with remote application processes in the safety related equipment. b) the optional service interface 2 between non-safe applications or support applications and the Communication Functional Module (CFM).

12 8. COMMUNICATION FUNCTIONAL MODULE See [5]. 8.2 Service definition See [5] Model of communication services See [5] The following option shall not be required for ETCS level 1 radio in-fill: a) Optionally, more than one transport connection per physical channel can be supported by a CFM The HP service shall not be required for ETCS level 1 radio in-fill Connection establishment See [5] Optionally, the track-side CFM can establish transport connections. This option shall not be required for ETCS level 1 radio in-fill unit Data transfer See [5] Connection release See [5] High priority data The HP service shall not be required for ETCS level 1 radio in-fill 8.3 Communication protocols See [5] Introduction See [5].

13 8.3.3 Data Link Layer See [5] Network Layer See [5] Transport Layer See [5] Multiplexing of two or more transport connections onto a single network connection can be provided as an option. This option shall not be required for ETCS level 1 radio in-fill Application conditions of X See [5] Time sequences See [5]. 8.4 Management of Communication Functional Module See [5] Call and ID-Management See [5] The EURORADIO System communication functional module offers optionally several logical connections between the trackside and the onboard equipment via the same physical channel.
