In addition to the dimensional requirements, the room where the exchange is to be installed
must definitely comply with the requirements below. In case the room fails to be appropriate,
the installation personnel should ask for the assistance of the related authorities to find a
suitable place.
The following requirements should be fulfilled prior to the installation of the exchange:
1- The exchange of the DS200 series should be installed in places that are not exposed to
direct sunlight and not humid, but that are ventilated, well lit, with an environmental
temperature of 5-40
o
C.
2- It should not be exposed to effects of dust, vibration, grease and water.
3- Devices that generate high frequency waves (such as welding machines, office
equipment such as computers and telex machines, air conditioners, TV sets, etc.) should
not be in the same room if possible, and they should be at least 3 meters away from the
exchange, otherwise.
4- The mains supply connection of the exchange should be dedicated to the system. The
requirement that the system power should be uninterruptible is supposed to be
considered while the connection is performed, and if possible, the system should be
powered from an independent and well-grounded source.

POWER FEED THAT IS INTERRUPTED FREQUENTLY MAY AFFECT
ADVERSELY THE PROPER OPERATION OF THE SYSTEM!
5- The position of the spot where the exchange cabinet is to be placed should be
considered with regard to the location of the main distribution frame (MDF) and cables.
Such a location should be chosen that the covers could be opened easily and the system
could be reached easily in order to facilitate installation and later maintenance.
6- Since the installation connections are made behind the cabinet, the positioning of the
cabinet should be arranged accordingly. The illumination arrangement at the back of the
cabinet has been included in order to facilitate the installation work.
XI.1.B. STRUCTURE OF THE CABLE GUIDES:
Determining the structure of the cable guides, their positioning, entrance point to the room
where the exchange is to be installed, as well as the structure of the cable guides that are to
be used within the room, are extremely important especially for the cases where large-
capacity (more than 256 lines) exchanges are to be installed. It is essential to extend all
cables, which connect to the exchange, through cable guides regarding installation safety
and efficient operation of the exchange. It must be considered while cable conduit planning
that the power cables, the cables carrying 2 Mbit signals and the cables carrying analog
signals are supposed to extend through separate cable guides.
