NovaTec
Mobile Gateway S20
4.4
Laying the Cabling
All connections except the mains power cable and the earth cable are connected to the NovaTec
Mobile Gateway S20 from the front. The mains power cable is connected from the back using
the cable that has already been fitted for this purpose. All local loops, antennas and extension
lines are connected via special connectors located on the front panels of each of the slide-in
modules. In order to avoid overheating the system, please ensure while laying the cabling that
the air circulation is not obstructed.
4.4.1
Strain Relief and Positioning of the Cables
All lines that leave the system must be strain relieved at an appropriate place (see illustration in
Picture 2). In the 19“ System the cables are simply of fixed to the frame with a cable binder. You can
therefore use any place on the frame. Each of the wires for the lines for the local loops and the
terminal equipment interfaces are colour coded. The definition of each colour can be found in Chapter
4.11.
4.3
Mounting
After the NovaTec
Mobile Gateway S20 has been removed from the box, select the desired
location for mounting the system according to the criteria given in Chapter 4.1.1. TheNovaTec
Mobile Gateway S20 is built in a 19“ rack into which the individual modules are to be inserted.
Both the backplane and the mains power cable are already fitted to this rack. A number of
antenna cables between the WAU and the ACU are installed in accordance to the ordered
configuration (number of mobile channels).
Please decide as early as possible, whether you will connect the terminal equipment
to the system in a bus structure or a star-shaped (Category 5) cabling format. If
using a star-shaped cabling format, the relevant terminating resistors must be
deactivated (see Chapter 4.11).
Take care that you begin with Pin 32 (Plug 2) when connecting the cabling
to the trunk and terminal equipment interfaces of the CCU.
