Purpose
Aim
The aim of this specification is to define the requirements for a basic bit to bit Time Division Multiplex (TDM) transmission system suitable for use in a variety of signalling applications on Railtrack.
Bit to bit describes a one to one relationship between the input at one end and the output at the other. This may include multi-drop applications. It specifically excludes any bit manipulation such as panel processing or button processing.
The requirements address the needs for modern signalling schemes, whether for new works or as part of a renewal, and thus reduce the level of prescriptive detail in tenders regarding the TDM system.
