SYSTEM DESCRIPTION
2. Call Termination to Visitor PS
a. The Home PBX receives the call to a Home PS from another PBX.
b. The Home PBX refers the HLR information of the PS.
c. From the Roaming Number contained in the HLR information, the Home PBX detects whether the
Home PS is roaming.
d. The Home PBX inquires of the Visitor PBX about the call termination to the Visitor PS. The inquiry
contains the roaming data of the Visitor PS, such as Roaming Number and Individual PS Number.
e. The Visitor PBX analyses the Roaming Number, and refers to the VLR information of the Visitor PS
in accordance with the Individual PS Number.
f. The Visitor PBX confirms the VLR information.
g. The Visitor PBX terminates the call to the Visitor PS.

SYSTEM DESCRIPTION
4.4 Multi-Site Roaming System Condition
1. Trunk
Multi-Site Roaming can be executed only on trunk connection between PBXs based on JT-Q931a pro-
tocol.
To each trunk route of JT-Q931a trunks, it can be specified whether Multi-Site Roaming is provided or
not.
The JT-Q931a trunks can be used by Single Line Telephone stations and Dterm stations for originating
or receiving calls as same as common trunks.
2. Data Base Module
An AP00 card for Data Base Module (DBM) is required per PBX.
The AP00 card can not be used as Billing Application Processor (for SMDR, MCI, PMS or Hotel/Mo-
tel features).
System data stored in the memory of the AP00 card can be saved, loaded and verified from a MAT.
(Memory Area No.:A, Memory Address: 00900-10870, File Extension: DMA)
A Roaming network can consist of maximum 512 PBXs.
Visitor Location Register (VLR) information for maximum 512 Visitor PSs can be recorded to a sys-
tem.
VLR information is the various information of Visitor PS and is made in the memory of AP00 on the
Visitor PBX when the PS is roaming.
When the VLR information exceeds for more than 512 PSs, AP00 overwrites the oldest VLR informa-
tion.
3. Home PS/Visitor PS
To use the PSs for Multi-Site Roaming, the following must be assigned to the PSs.
- SYS-ID; SYS-ID of Home PBX.
- PS-ID; An unique number for identifying the PS.
- Individual PS Number; The same number with the Home PBX ID.
- Extension Number; The same number with the Individual PS Number.
- Network ID; It must be assigned when the Roaming Network adopts Network ID Methods.
- Home PBX ID; An unique number for identifying the PBX on the Roaming Network.

CHAPTER 3 INSTALLATION
1. GENERAL
This chapter details the installation procedure to provide WCS functions 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.
