Chapter 13 Voice Over IP (VoIP)
6. Because the IP station can have only two-operation mode (Location number), when the number of
remote sites (Location numbers) is over two, there is a case that the appropriate communications
may not be available. Refer to Example 2 for details.
Location number in each operation mode for each IP station:
<IP stations in Location #0: STA. 200 and 201>
Remote Connection Mode: Location #1
Local Connection Mode: Location #0
<IP stations in Location #1: STA. 202 and 302>
Remote Connection Mode: Location #1
Local Connection Mode: Location #0 or #2
<IP stations in Location #2: STA. 300 and 301>
Remote Connection Mode: Location #1
Local Connection Mode: Location #2
Operation mode for each IP terminal:
<IP terminals in Location #0>
Local Connection Mode
<IP terminals in Location #1>
Remote Connection Mode
<IP terminals in Location #2>
Local Connection Mode
Example 1: When Sta. 200 logs in Location #1
STA. 200 logs out from Location #0, and then logs in from IP terminals in Location #1. STA
200 works in Remote Connection Mode (because IP terminals in Location # 1 are assigned to
Remote Connection Mode.), under the conditions of Location #1 (because STA. 200 in
Remote Connection Mode is assigned to operate under the condition of Location #1.). In this
case, the appropriate communication is available because the operating condition of STA.
200 matches the actual Location number (Location #1).
Example 2: When Sta. 200 logs in Location #2
STA. 200 logs out from Location #0, and then logs in from IP terminals in Location #2. STA.
200 works in Local Connection Mode (because IP terminals in Location # 2 are assigned to
Locale Connection Mode.), under the conditions of Location #0 (because STA. 200 in Local
Connection Mode is assigned to operate under the condition of Location #0.). In this case, the
appropriate communication may not be available because the operating condition of STA. 200
(Location #0) does not match the actual Location number (Location #2).
