3.7 Cable Termination and Cross Connection from the MDF to the DRU and from the DRU to the D
Analog PB TEL
This paragraph explains the following work procedures.
•
Cable Termination and Cross Connection from the MDF to the DRU
•
Cross Connections for Digital Interface (When remotely installing the DRU-23-S3 by the digital interface)
•
Cable Termination and Cross Connection from the DRU-30-A to the Analog PB TEL
•
Cable Termination and Cross Connection from the DRU-23-S3 to the D
Note 1: Provide the necessary cross connection at the MDF by using copper wires of 0.5 mm diameter (24 AWG).
Dual-core twisted wire is used for speech path, and single-core wire is used for control. It is recommended
that wires of different colors be used for trunks, station lines, PFT, etc., so that they can easily be distin-
guished.
Note 2: DRU-30-A/DRU-30-S3 cannot be remotely installed by means of digital interface.
