CHAPTER 3 INSTALLATION
1. GENERAL
This chapter details the installation procedure and work contents involved in providing ISDN to the PBX.
2. PRECAUTION IN HANDLING
The installer must wear the grounded wrist strap to protect the circuit card from static electricity, when handling
cards, and the installer must engage in the work on a grounded conductive work surface. (See Figure 3-1).

3. REQUIRED EQUIPMENT
3.1 Required Equipment for ISDN with PRI
Table 3-1 below shows the equipment required when providing ISDN with Primary Rate Interface to the system.
Note:PLO card (PN-CK00) is required when the PBX needs to interface with two clock supply routes with different frequen-
cies, e.g., DTI Trunk (1.544 MHz) and BRI Trunk (192 KHz or 2 MHz).
For example: T1 at 1.544 MHz, and 192 KHz or 2 MHz for BRI Trunks: In this condition a PLO card is required. 
3.2 Required Equipment for ISDN with BRI
Table 3-2 shows the equipment required when providing ISDN with Basic Rate Interface to the system.
Note:PLO card (PN-CK00) is required when the PBX needs to interface with two clock supply routes with different frequen-
cies, e.g., DTI Trunk (1.544 MHz) and BRI Trunk (192 KHz or 2 MHz).
For example: T1 at 1.544 MHz, and 192 KHz or 2 MHz for BRI Trunks: In this condition a PLO card is required. Table 3-1  Required Equipment for ISDN with PRI
