1. CROSS CONNECTION OF STATIONS
Note 1: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 distinguished.
Note 2:For cross connections between stations and C.O. lines for PFT, refer to Section 3. “CROSS CONNEC-
TIONS FOR PFT” in this NAP.
