Subaddress
Using a subaddress enables you to connect up to eight ISDN terminals to the same ISDN telephone
number and line. The terminals are addressed by using different subaddresses.
To call a terminal with a subaddress, separate the ISDN telephone number and the subaddress with
a ‘*’.
EXAMPLE: 12345678*2 (UP TO FOUR DIGIT SUBADDRESSES ARE POSSIBLE)
If you want to use this ISDN line, you need to set ‘Enabled: On’ and enter the numbers of your
ISDN line. If some of the ISDN lines are not to be used, set ‘Enabled: Off’. Line 1 should always
be enabled.
National ISDN and AT&T Custom ISDN might require SPID numbers associated with your ISDN
numbers. If you have received two different SPID numbers for each ISDN line from your telephone
company, you must program both.
Example:
