Is there any way to set the clock and date on the SX20 when there is no possibility of connecting an NTP server?
The system is in a closed area with no network connections available. I have seen where the ISDN Link time and date can be set, but it doesn't seem to cross over to the SX20.
The complete system is the SX20, ISDN Link, Data switch / Kiv 7 and Adtran ISU 512
Thanks
