We have a small Panasonic telephone system, inhouse. The cover is labelled Panasonic KSU VB-42050 for Model 824.
Inside the box are two jacks one labelled C01 and C02, the other labelled C03 and C04. For some time, there have been 3 lines incoming from the telco, using C01,C02,C03.
Recently, we got a fourth incoming line. It is live all the way into the phone system (C04), but doesn't show up as an active line through the system to the stations.
I've looked for dip switches on the boards and only find one group, one switch-set per incoming line. They're all set the same already; I was hoping C04 would be set differently indicating 'not in use' or something.
How do we enable this line so that it's treated as an active line within the system and through to the stations as Line 4? Is it a hardware function or software?
If software, am I looking for a reference guide for something called "VB-42050" or for a Model 824?
Thanks in advance for your guidance of the clueless.
