For identification each cable shall be marked with cable tag number clearly visible inside
cabinets. For smaller units the cable identification shall be located outside the unit (outside the
cable glands).
When the number of cables makes it difficult to locate each cable, the first pair in the cable
shall be marked with the cable tag number.
The armour shall be tied back, covered with a yellow/green sleeve and terminated on the
Protective Earth Bar (PE).
The screen shall be covered with a transparent sleeve and terminated on the Telecom Earth Bar
or isolated based on criteria as below:
• For interconnection between a main equipment cabinet and a Field Termination Cabinet
(FTC) or main Distribution Frame (MDF) the screen shall be terminated in the FTC/MDF
and isolated in the main cabinet.
• For interconnection between main equipment cabinets the screen shall be terminated in one
end only. Preference shall be given to the main equipment cabinet seen as the origin of the
cable.
• For interconnection between Field and Central Equipment the screen shall be terminated in
the Central equipment and isolated in the Field Equipment.
The cable cores shall have sufficient length to reach all terminals in the terminal block.
Wires shall be terminated using a crimped lug or ferrule. The lug shall be applied using
appropriate tools for the application.
All cores shall be terminated.
Individual cores shall be identified with a closed slip-on type of plastic identification ferrule
carrying a number identical to the terminal (not valid for “plug type” connections).
For terminal blocks of IDC type or similar (Krone, Wago, Bix blocks, etc.) the correct tool
shall be used for core insertion. Knives, screw drivers, etc. shall not be used.
For twisted pair type of cable the cores shall be kept revolved as close as possible to the
terminal.
The correct tool for the application shall always be used.
Testing
Testing of Special Cables shall be performed at the end of installation or in the mechanical
completion/pre-commissioning phase.
