Hello everyone, this is my first post on the forum, so "Hi!"

I have inherited the management of a Samsung OfficeServ 7100 phone system. At the customer's request, I have added a 4DLM card to Slot 2 to accommodate additional handsets. It works - i.e. the handsets power up and can make calls to other extensions and can answer and call out on the CO lines, but they don't have extension numbers. Instead, the displays show just a ':' character and the assigned station name.
I've been digging through the web interface and programming manual trying to find out how to assign extension numbers to these handsets but am not getting anywhere. Can anyone advise the proper procedure for assigning extensions numbers to a newly added 4DLM card?

Thank you very much for any assistance.
