INSTALLATION PROCEDURE
3. CROSS CONNECTIONS FOR PFT
Note 1:
The COT must be accommodated in a universal slot of the same Unit (U) in which the cross-connected PFT
is mounted. See the figure below.
Note 2: Provide the necessary cross connections at the MDF by using copper wires of 0.5 mm diameter (24 AWG).
2-core twisted wire is used for speech path, and single-core wire is used for control wire. It is recommended
that wires of different colors be used for trunks, station lines, PFT, etc., so that they can easily be distin-
guished.
