10.2 Cables Between The PBX And MDF
Regarding lines, trunks, and NCU (PFT), 25P shielded the PBX and the MDF are connected using cables with
a CHAMP (Amphenol) connector at one end.
Table 2-11 shows the procedure for calculating the required number of cables. Figure 2-18 also shows an outline
of cable connections from the Module Group to the outside.

CHAPTER 3 INSTALLATION PROCEDURE
1. GENERAL
This chapter explains the procedures for installing the PBX, the Maintenance Administration Terminal (MAT),
Desk Consoles, and various types of terminal equipment (single line telephones, D
terms, Data Modules, etc.).
The procedures explained in this chapter are shown in Figure 3-1.
Before beginning the installation, thoroughly read Section 2., “PRECAUTIONS BEFORE BEGINNING IN-
STALLATION” and observe the precautions...

INSTALLATION PROCEDURE
2. PRECAUTIONS BEFORE BEGINNING INSTALLATION
2.1 Outline
1. Before beginning the installation, check to see if the installation requirements (grounding, the quantity and
kind of installation cables, etc.) are all present by referring to Chapter 2 of this manual.
2. For a standard installation, the system is installed on a free-access floor, so no explanations are provided
pertaining to cable racks and cable ducts.
3. The PBX is connected to...

INSTALLATION PROCEDURE
4. As the cable to be run between the PBX and the Rectifier, use a CV cable (600 V Crosslinked Polyethylene
Insulated PVC Sheathed Cable) as the circumstance permits. Compared with an ordinary IV cable (600 V
PVC Insulated Cable) the CV cable is stronger because of its thicker cover. Thus, it is suitable to run along
the free-access floor where it is difficult to protect the cable from damage.
Also, for easy identification of different...

3. INSTALLATION PROCEDURE
The flowchart in Figure 3-2 shows the steps of the installation procedure. Each step is assigned a NAP number.
NAPs NAP-200-001 through NAP-200-018 follow Figure 3-2. These NAPs should be followed sequentially
when performing the installation. Individual steps, such as installation of SMDR, can be performed indepen-
dently by referring to the corresponding NAP.

A sufficiently illuminated room. (200 lux at floor level). 
A location around which there are no obstructing objects, 
thus allowing easy maintenance. 
A place where C.O. lines can be brought in, or local 
cables can be brought up to the MDF easily. 
A place where communication and security ground can 
be obtained...
