Specifies dimensions that will ensure the mechanical interchangeability of subracks and of plug-in units. Covers the basic dimensions of a modular range of subracks for mounting in equipment together with the basic dimensions of a compatible range of plug-in units and printed boards. Specifies the standard positions of free connectors such that plug-in units are mechanically interchangeable in subracks with corresponding fixed connector positions. Also includes tables and diagrams.
