What is BS EN 61375-2-5 — Train communication network about?
BS EN 61375-2-5 is a part of an international multi-series standard that discusses train communication network systems (TCN).
BS EN 61375-2-5 defines Ethernet Train Backbone (ETB) requirements to fulfil open train data communication system based on Ethernet technology.
BS EN 61375-2-5 stipulates the technical specifications such as related terms and definitions, conventions, Ethernet Train Backbone (ETB) physical layer, ETB data link layer, ETB network layer: IPv4 subnets definition, ETB Transport layer, ETB Train Inauguration: TTDP, ETB ETBN redundancy, ETB physical train naming convention, ETB Quality of Service, ETB Management and monitoring, ETB Application interface, ETB conformity statement, etc.
Note 1: BS EN 61375-2-5 may be additionally applicable to closed trains and multiple-unit trains when so agreed between purchaser and supplier.
Note 2: The PICS proforma specification and the related conformity test are not in the scope of BS EN 61375-2-5.
Who is BS EN 61375-2-5 — Train communication network for?
BS EN 61375-2-5 on Train communication network is useful for:
- Manufacturers of train communication equipment
- Maintenance staff for train communication system
- Manufacturers of electronic railway equipment
- Regulatory authorities
Why should you use BS EN 61375-2-5 — Train communication network?
Ethernet train backbone (ETB) uses physical lines along the train to connect the active network devices together (ETBN, Repeater, etc.). These lines are also called physical segments and can use passive components such as cables and connectors, dedicated to Ethernet.
BS EN 61375-2-5 defines the Ethernet Train Backbone that helps train operators and users to achieve interoperability between the Consists of different types when coupled in the same train composition.
BS EN 61375-2-5 follows the ISO-OSI model and specifies the whole protocols stack from the physical layer up to the application layer, which helps you get a clearer idea to follow the application system.
A Protocol Implementation Conformance Statement (PICS) proforma allows suppliers to state their conformity to BS EN 61375-2-5. It recommends that all Consist Network definitions should consider it to preserve interoperability.
