3. IP-BS Installation Design

IP-BS is not for the North American market.

Wireless Synchronization Kind

When assigning IP-BS data to the Telephony Server, you can select one of the following three wireless synchro-

nization kinds:

PRIMARY IP-BS: This IP-BS supplies clock signal to other IP-BSs. PRIMARY IP-BS itself will synchro-

nize to the CS or CS/IP-BS of the other specified system. If PRIMARY IP-BS cannot find the CS to be

synchronized, it operates without synchronization, supplying clock to other IP-BS as the primary.

SUB-PRIMARY IP-BS: This IP-BS can operate as a primary IP-BS only when PRIMARY IP-BS is down.

SUB-PRIMARY IP-BS must be installed at a proper location so that the wireless area of PRIMARY and

SUB-PRIMARY may overlap one another. Under normal circumstances, it functions as a secondary IP-BS.

SECONDARY IP-BS: This IP-BS establishes the synchronization by receiving the sync signal from the

IP-BS that has the same SYS-ID and the synchronization has been established

Assign PRIMARY IP-BS and SUB-PRIMARY IP-BS for each wireless block (Group of wireless area that over-

laps directly/indirectly other area) within IP-BS installation design. At this time assign the IP-BSs in the middle

as PRIMARY and SUB-PRIMARY BS, and PRIMARY IP-BS and SUB-PRIMARY IP-BS need to be assigned

next to each other's wireless area. When wireless block is to be composed of multiple IP-BSs, assign PRIMARY

IP-BS and SUB-PRIMARY IP-BS respectively. When wireless block is to be composed of one IP-BS, assign

the IP-BS as a PRIMARY IP-BS.
