3 Site Planning
Conditions for Configuring the Air Synchronisation
•
Master CS2 must be within range of Master CS1.
•
It is recommended that Master CSs be placed in the middle of the installation site.
•
Both a Primary CS and Secondary CS should be assigned to Slave CSs.
•
When using only two IP-CSs on the network (only two IP-CSs are connected to the PBX), make sure that
you do not create a Master CS2.
•
All traditional CSs are automatically assigned and fixed as Master CS1.
•
When using IP-CSs and traditional CSs in the same area, make sure that you do not create a Master CS2.
•
When synchronising CSs, do not create loops as in the examples below:
[Examples]
•
It is recommended that the number of levels in the synchronisation hierarchy is minimised for stable air
synchronisation. The maximum number of levels is 4.
Notice
A repeater can only receive the clock signal from one source CS (Secondary CS cannot be set). Therefore,
when you extend the coverage area using repeaters, minimise the number of IP-CSs that are synchronised
with the repeater.
Note
For your convenience, IP-CSs are automatically classified according to the order of their registration to the
PBX. Therefore, it is recommended to register the CS that you want to assign to Master CS1 first. For
example, when using IP-CSs and traditional CSs in the same area, connect the traditional CSs to the PBX
first.
