CHAPTER 1 GENERAL INFORMATION
System Outline
SYSTEM OUTLINE
The Wireless Communication System (WCS) interfaces with a Personal Station (PS) via a Zone
Transceiver (ZT).
Three types of system configurations are available:
(1) Integrated Type
The system provides both PBX and WCS functions.
(2) Adjunct Type (Analog Interface)
The WCS is an adjunctsystem to the PBX linked by LC-COT connection.
(3) Adjunct Type (CCIS Interface)
The WCS is an adjunctsystem to the PBX linked by CCIS interface.
Figure 1-1shows the system outline of the WCS.

SYSTEM CAPACITY
NOTE 1:When using a PZ-M537 card, the capacity of PSs can be expanded to 256.
NOTE 2:Calling Area is a registered area to search first for a PS location.
The calling signal is sent to the ZTs that belong to the Calling Area.

TIME SLOT ALLOCATION
CSH
As shown inFigure 1-2, the CSH (PN-2CSIA) card uses the time slot on the basic memory
Highway 4. Therefore, the total number of time slots for all CSH card must be 128 time slots or
less including all other application processor cards, which use the Highway 4.

OUTLINE OF MULTI-SITE ROAMING
The PBX supports the JT-Q931a protocol and JT-11582 for signaling at Q-reference point
between PBXs on the private network. By supporting this protocol, the PSs can be used in any
Calling Area on the private network.
