Integrated Services Digital Network (ISDN)

Description
The system can manage a call received from the ISDN line by point-to-point or point-to-multi-
point configuration.
An optional ISDN Line Card/Unit, KX-TD280, KX-TD281, KX-TD282, KX-TD286, or KX-
TD290 is required. The KX-TD290 can only use "point-to point" configuration.
Point-to-point
A call received through one ISDN port is sent directly to a specific extension using a
Direct Dialling In (DDI) service.
Point-to-multi-point
One ISDN port can support a maximum of ten Multiple Subscriber Numbers (MSN). A
call received through an ISDN port is sent directly to the pre-assigned extension if the
dialled number matches the stored MSN.
