Programming switchboards: Special program settings for door entry systems?

For the interphone function in the telephone switchboard two settings are possible.
The first setting 98 1234 66 1 R allows the interphone call ringtone to be changed, switching from one ring on pressing the call button to a ringtone consisting of two rings repeated every 5 seconds for a duration of 30 seconds.
The second setting concerns the duration of the excitation time of the relay connected between terminals 12 V and B of the interphone interface.
The duration is between 1 and 50 seconds. The setting is 98 1234 67 yy R. Where yy is the number of seconds to be set (01......50).
