scope:

This part of IEC 62580 specifies the general architecture of the On-board Multimedia and Telematic Subsystem, which includes four categories of multimedia and telematic subsystems identified as:

A Video surveillance/CCTV

B Driver and crew orientated services

C Passenger orientated services

D Train operator and maintainer orientated services

This part establishes:

• the boundary between the OMTS and the on-board communication system, as described by the IEC 61375 series

• the methodology to describe an OMTS in terms of abstract model

• the general principles and the basic requirements to specify the services provided/needed by each category

• the approach to ensure interoperability between services

This part gives guidelines for:

• OMTS classification

• functional breakdown structuring

• system breakdown structuring

• formal specification of an OMTS

This part is applicable to any type of train, e.g. open trains, multiple unit trains and closed trains.

NOTE The general architecture provides a common basis for the application categories defined in part 2 and possible future parts of this series of standards. Consequently, the approach is homogeneous for all multimedia and telematic subsystems addressed by this series of standards.
