PREFACE
The objective of this manual is to guide and provide the installer with the necessary
information about the installation of the C-DOT MAX-XL. It is for this reason that
more emphasis has been put on the overall installation information than the
detailed step by step procedures.
This manual includes various chapters on floor marking, grouting, iron work
installation, cable preparation and laying, IOP installation etc. Each chapter covers
a brief introduction about the activity, material and tools required for performing
the task and a description of the installation procedure. It is hoped this manual will
serve as a useful reference to the installer.

INSTALLATION MANUAL 9
Chapter 1.
Floor Marking
1.1. 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.
1.2. STANDARD TERMS
1.2.1. Floor
Floor means the normal floor covered with suitable antistatic material.
1.2.2. Datum Line
A datum line is a straight line drawn through the maximum no. of points
located at a distance, say D, from the wall of the Switch Room/IOP Room.
1.2.3. Reference Point
It is a point on the Switch Room/IOP Room floor to which the datum lines
and subsequent measurements are related. It is also defined as the
intersection point of the two datum lines drawn at right angles to each other.
1.2.4. Suite End Line
This is the line drawn parallel to one of the datum line from which the suite
will begin or start growing.

Chapter 1.
10 C-DOT DSS MAX-XL
1.2.5. Suite Lines
These are the lines drawn parallel to the other datum line (one referred in
suite end line) perpendicular to suite end line and coincide with the periphery
of the Base mount Assembly.
1.2.6. IOP Lines
These are the lines drawn parallel to one of the datum lines, and coincide
with the periphery of the IOP cabinet.
1.3. MATERIAL & TOOLS REQUIRED
S. NO. DESCRIPTION QUANTITY
1. T Square (1 meter) 1
2. One meter long flat steel scale 2
3. String (silk thread) for marking 10 M
4. Ultra marine indigo or Blue ink for temporary
marking 1
5. Highlight marking pens of black ink 4 Kg
6. Steel measuring tape of 15M length 2
7. Set Square 1
8. Brass Screws (2mm to 3mm with a cut on top) 30
1.4. MARKING PROCEDURE FOR SWITCH ROOM & IOP ROOM
1.4.1. Marking of First Datum Line
Mark some points along the length of the room at a distance of 600mm from
the wall. Draw a line such that it passes through a maximum number of the
points. To draw the line, soak a silk string of required length in ultra marine
indigo or blue ink. Place it over the points by holding the string tightly at
both the ends. Pull the string from the middle and release it so that it leaves
an impression on the floor. This line is called the first datum line. Refer Fig.
1.1.
1.4.2. Locating Reference Point
Mark a point on the first datum line at a distance of 600mm from the
adjacent wall. This point is called the Reference Point. Fix a brass screw at
the Reference point to mark it permanently. This point is denoted as `X' in
Fig. 1.1.
