## ISDN Time synchronisation

## Definition

The time synchronisation defines the automatical adjustment of summer time and winter time over the ISDN network.

## Use

This function is used to synchronise the ASB 150 02 automatically with date- and time information from the ISDN public network.

## Operation

The ISDN public network transmits the date- and time information, so that the ASB 150 02 system, which is connected to the ISDN network, can extract it with an certain ISDN message to adjust the exchange automatically.

The ISDN time syncronisation can only be switched ON/OFF by specifying the ISDN link number of one link from the external date- and time information.

## Capacity/Limitations

The updating of the date- and time information is only possible, when ISDN call(s) is/are in process. If no ISDN call is done, then the date- and time information will not be adjusted although the feature is switched on.

If the date- and time synchronisation is sucessfull, all wired system extensions (which are connected to the ASB 150 02 system ) with an approprirate display will be updated within the next minute.

This feature is not available for cordless phones.
