2 Overview
2.2 System Overview
This CS can be connected to a PBX via LAN. The CS supports existing DECT PSs. When activation keys are
installed, the number of simultaneous calls increases from 4 to 8.
The CS provides the following:
–
Speedy installation
Through LAN synchronization, installation can be performed as quickly as with traditional CSs.
–
High quality communication even in environments where reception can be difficult
In reflective environments such as a warehouse with steel or metal walls, noise and cutouts can be a
problem. Call control settings can be used to reduce noise and provide high quality communication.
(KX-TCA185/KX-TCA285/KX-TCA385 only).
–
Expansion using activation keys
By installing activation keys, the number of simultaneous call channels can be increased from 4 to 8. This
is effective in the area where needing more simultaneous call channels. For information about the type of
activation key codes available, refer to "Optional Accessories".
Air Synchronization/LAN Synchronization
The unit supports the following two synchronization methods.
•
Air Synchronization
Each Slave CS is connected to the Master CS or another Slave CS "over the air". This method should be
used when adding this unit to an existing network where CSs cannot connect via a LAN connection, or a
network containing old IP-CSs. This kind of network is limited to the distance radio waves can travel
between CSs.
For details about air synchronization, refer to "5.6 Air Synchronization". For more details about adding this
unit to an existing network, refer to "5.7 Synchronization with Traditional CSs or Old IP-CSs".
•
LAN Synchronization
Each Slave CS is connected to the Master CS via a LAN connection.

Since LAN synchronization has several benefits compared to air synchronization, it is recommended
to use LAN synchronization when possible. If LAN synchronization is not possible, use air
synchronization.
The benefits of LAN synchronization are listed below.
•
Creating a synchronization hierarchy is not required. Therefore if one CS fails, the other CSs are not
affected.
