Configure==>Boards==>Ports==>ISDN Ports

To view, edit, reset, and refresh the configuration of ISDN ports on an active PortMaster 4, click Boards==>Ports==>ISDN Ports.

Configure ISDN PRI connections first in the Configure==> Boards==>Lines panel. ISDN port assignments are then made automatically by the PortMaster 4. These default configurations require no further settings, but can edit them in this panel.
