•
The compensation of the synchronization signal propagation time between the "Slave" PBX
and the "Master" PBX must be defined: 5 switches are used (serial printing: RET4-0, each
switch = step of 100 meters).
Note:
Binary value : ON = 0 ; OFF = 1
When adding a synchronization delay, the ON position of the switches signifies 0
(and thus a delay of 0 seconds).
•
Check the configuration of switches CA1, CA3 and CA4 on the CSI card. Their configuration
must be the same as the factory configuration (see mono-site synchronization).
•
Check the configuration of switches CA1, CA2 and CA3 on the RMH cards (see mono-site
synchronization).
