CHAPTER 2 SYSTEM DESCRIPTION
1. GENERAL 
This chapter explains the system configuration, additional hardware and system specifications pertaining to the 
WCS. 
2. SYSTEM CONFIGURATION
2.1 System Outline
The wireless communication system (WCS) is interfaced with a Personal Station (PS) via a Zone Transceiver 
(ZT). 
When installing the WCS, there are three types of systems: 
1. Integrated Type The NEAX2000 IVS/1000 IVS provides both PBX and WCS functions.
2. Adjunct Type [1] The WCS is an adjunct system to the existing PBX linked by LC-COT connection.
3.   Ad jun ct  Type  [2]
The WCS is an adjunct system to the existing PBX linked by CCIS.
F igu re  2-1  shows  the sy ste m  di agr am of  the  W CS.
