PBX Time
The PBX has an internal clock that returns the PBX time (time and date) on the connected end devices. If the end device is so equipped, the PBX time will be displayed on the end device.
Furthermore, the PBX time is required to carry out functions such as switching configurations as well as wake-ups.
During a power failure or PBX reset, the PBX time is lost. There are several ways to update it:
Manually
Take from PC
Via the network
Using the buffered real-time clock – saves the time for approx. two hours in the case of a power outage.
Via ISDN/external S0 port (optional, see Technical Data in Manual)
* Note: The switch to/from daylight savings is done automatically for the PBX time.
Proceed as follows for configuration:
-Using the Configuration Manager (page Administration > Date and time of the PBX)
