9. CROSS CONNECTIONS FOR D
term Series E
Note 1:
Provide the necessary cross connections at the MDF 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.
Note 2:The maximum distance between the Module Group and Dterm is 850 meters (2459 feet). The installation
cable must be 24 AWG (0.5 mm dia.) or larger.

Cable running Referring to Figure 015-14, run the cables between 
each D
term and its Modular Block (Jack), and 
between the Modular Blocks and the MDF.
Protect the cables by using cable ducts, etc.
Termination of cables Referring to Figure 015-14, terminate the installed 
cables to the MDF and the Modular Blocks.
Check terminal locations on the 
Module Group side of the MDFReferring to Port Accommodation sheet and 
description of 16ELC card in the “Circuit Card 
Manual,” identify the lead names for the ELC card 
and the terminal locations of the leads.
END
Cross Connection Referring to Figure 015-14, provide the necessary 
cross connections at the D
term side and the PBX side.

INSTALLATION PROCEDURE
10. CROSS CONNECTIONS FOR DIGITAL INTERFACES
Perform the cross connections for digital interfaces as shown below:
Note 1:When your system is single IMG configuration, time division switch (TSW) card is equipped with Phase
Lock Oscillator (PLO). Therefore no dedicated PLO card is required to use Digital Interfaces. However,
when the system requires a higher-precision oscillator, use the Oscillator (OSC: PA-CK14) card. The cards
may be mounted in slots numbered 9, and 17 of PIM0. For the OSC card, no external wiring is required.
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.

(DTI, CCT, PRT)Referring to the Port Accommodation 
sheet and description of Digital Trunk 
card in the “Circuit Card Manual,” 
identify the lead names for the Digital 
Trunk card and the terminal locations 
of the leads.
PLO leads Referring to Figure 015-15/Figure 
015-16 to identify the lead names and 
the terminal locations for the PLO.
Cross Connection
Note
When accepting synchronization 
clocks from other node (master or 
submaster node)Referring to Figure 015-17/Figure 
015-18, provide the necessary cross 
connections.
When accepting synchronization 
clocks from External High-Stability 
OscillatorReferring to Figure 015-17/Figure 
015-18, provide the necessary cross 
connections.
END
WARNING: 
 Back card out of the module before attempting cross connection. Otherwise, the fuse mounted
on the DTI card will blow and the card will become inoperative.

INSTALLATION PROCEDURE
This NAP explains the installation of the DESK CONSOLE and Cable Connection. Figure 016-1 shows the outer
view of the DESK CONSOLE. Use the PA-CS33 (ATI) card as an interface card between the system and the DESK
CONSOLE. The card can connect a maximum of two DESK CONSOLEs.

START
Cable running While referring to Figure 016-2 through Figure 016-5, 
run the cables between each DESK CONSOLE and its 
Modular Block (Jack), and between the Modular 
Blocks and the MDF.
Protect the cables by using cable ducts, etc.
Termination of cables While referring to Figure 016-2 through Figure 016-5 
terminate the installed cables to the MDF and the 
Modular Blocks.
Check the terminal locations on the 
Module Group side of the MDSWhile referring to Port Accommodation sheet and 
description of PA-CS33 card in the NEAX2400 IMX 
Circuit Card Manual, identify the lead names for the 
card and the terminal locations of the leads.
Cross Connection While referring to Figure 016-2 and Figure 016-5, 
provide the necessary cross connection at the DESK 
CONSOLE side and the PBX side.
