INTRODUCTION

As a first step towards the installation of Exchange equipment (iron work, IOP-
PDP), the floor should be marked as per the exchange layout. Floor markings are
done in Switch Room where the main switching equipment is placed and IOP Room
where the input output processors with consoles are placed. The main aim of this
marking is to locate the exact position of the grouting holes which are used for
fixing the equipment in the respective rooms. This chapter covers the materials and
tools required and the detailed marking procedure. However, before carrying out
the floor marking, certain standard terms need to be understood and are therefore
defined.
