4.8.1 ISDN-BRI Settings
To make sure your system will work properly using ISDN-BRI, make the following settings:
1. Set ISDN switch type
2. Enter ISDN line numbers (+ SPIDs if required)
3. Disable unused lines
Some software versions do not support 6 ISDN lines, therefore some of the Line Setup entries
may be grayed out.
4.8.1.1.1 ISDN switch type
Select the type of ISDN network connected to your unit. Note that 1TR6 should only be used if
you are operating the system behind a PABX.
4.8.1.1.2 Line setup
This menu allows you to program the numbers associated with your ISDN line. 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 (Service Profile IDentifier) numbers for each ISDN line
from your network provider, you must program both.
