DS-2-Com
1.1 Background
Approved
All
DS-7-Com
The supplier of an interlocking system shall furnish a data preparation
tool that configures an interlocking system for a specific location.
Configuration concerns functionality and connection of the interfaces of
an interlocking system in accordance with the track layout and other
traits of a specific location.
Approved
All
DS-8-Com
The customer shall be able to use the supplier-furnished data
preparation tool to make modifications to their interlocking systems.
Approved
All
DS-3-Com
1.2 Purpose
Approved
All
DS-9-Com
The requirements in this document cover the supplier-furnished data
preparation tool that configures an interlocking system of a specific
model to a specific site.
Approved
All
DS-4-Com
1.3 Scope
Approved
All
DS-10-Com
These requirements refer to a data preparation tool that uses the EI
Interlocking Data File Format or a customer-specific data preparation
tool format as input. (EI means Euro-Interlocking.) In line with generic
and national functional requirements, the tool converts this data into
the form required to configure an interlocking system of a particular
supplier and model for a specific location. The conversion process takes
into account the characteristics and constraints of the specific supplier
and model. After this stage, verification and validation must be possible.
Approved
All
DS-11-Com
These requirements are closely related to the data preparation
requirements and these should be considered together.
Approved
All
DS-5-Com
1.4 Structure
Approved
All
DS-12-Com
