12.1. Feature Description Previous topic Parent topic Child topic Next topic

The “IPDA Different Time Zones (DTZ)” feature is used in situations when an IPDA shelf or access point (AP-IP) or HFA IP telephones are located in different time zones than the host system. In these cases, the local time of day should be shown instead of the system time on the display of the digital telephones that are connected to the remote AP or on the display of the HFA IP telephones.

Example for the local time display:

An OpenScape 4000 system in Houston (Texas) has one remote AP in Los Angeles (California) and one HFA IP telephone in New York (New York). All phones should display the local time.
