DK16 was 2 digit port numbers 00 to 15.
To make them all ring, go into programming, then:
[Sprk] 81 [Hold]
[Spkr] 00 * 15 turn on buttons from intercom up for as many lines as you have then [Hold]
[Spkr] ## [Hold]
[Spkr] ## [Hold]
All phones will now ring
If you want to do an individual phone, do this instead AFTER going into programming:
[Sprk] 81 [Hold]
[Spkr] ZZ where ZZ equals the port number then # then turn on buttons from intercom labeled button up for as many lines as you have then [Hold]
(Ext 10 = port 00,
(ext 11 = port 01,
(ext 12 = port 02,
do you see the pattern here,
you program by port, not extension.)
when finished:
[Spkr] ## [Hold]
[Spkr] ## [Hold]
When programming, the button you think of as an intercom button is counted as a normal button from one to ten, paper labels don't count in programming.
