5 Appendix
Note
•
The maximum number of hierarchy levels for a switch between Maser CS and Slave CS is 7 levels.
•
One LAN synchronization Master CS is required for each LAN Sync Group.
•
The first CS registered to the PBX becomes Master CS1 automatically. Master CS1 can be changed
using the PBX's Web Maintenance Console.
•
If necessary, you can set Master CS2-1 and Master CS2-2 (backup for Master CS1) using the PBX's
Web Maintenance Console. Master CS2-1 is connected to the same hub as Master CS1 and acts as
a backup if a problem occurs with Master CS1. Master CS2-2 is connected to a different hub from
Master CS1 and acts as a backup if a problem occurs with the hub containing Master CS1. Setting
Master CS2-1 and Master CS2-2 allows synchronization to continue when Master CS1 or Master CS1's
hub stops working.
