I've posted a really easy to follow Video for you on how to change the date and time on the SamsungProstar ( up to 70 more like this are available from abbeytel on youtube, all relating to issues on the Samsung Prostar) or go to http://www.abbeytelecom.com
Although I'm fairly confident about this answer, I'm not 100% certain. Looking at the manual, these look like phones that either have a server they report to and get their time from or set their clock automatically themselves using NTP or the like.

I think that the video may help work out your groups on the Samsung prostar DCS, there are over 60 'how to' videos at www.abbeytelecom.com ,(usually the main operator group is set as '500' with subsequent groups '501' 502' etc)
It sounds like your ISDN line has a fault or the Line card in your system ,although this shouldn't affect internal calls, you need to call your maintenance provider or find a Samsung Telecoms Engineer. I have posted a sample video for you which is one of nearly 70, explaining how to programme soft keys etc on the Samsung Prostar. we have posted these on youtube under 'abbeytel'. For written instruction visit
Please watch the attached video showing how to change the date and time on the Samsung Prostar - we have uploaded just under 70 of these 'how to' videos on youtube under 'abbeytel' or a written version is at http://www.abbeytelecom.com
Rather than write a complicated list of how to change the date and time on your samsung DCS I have posted a 'how to' video for you to watch ( over 60 more like this on youtube covering many issues, a written version is available at
This problem is either a fault on your ISDN line or a fault on your card in the Prostar system so you need to find a Samsung telecoms Eingineer. for other problems we have 60+ videos on youtube searching 'abbeytel' ( I posted a sample for you to look at) or visit http://www.abbeytelecom.com
