System Highlights
EXtra Device Port (XDP)*
Extension jacks 1 through 4 in the system support the connection of a digital proprietary
telephone and a single line device. The devices have different extension numbers and are
treated as two completely different extensions.
Parallelled Telephone Connection*
Extension jacks 1 through 4 in the system also support the parallel connection of a
proprietary telephone and a single line device. They share the same extension number and
are considered by the system to be one extension.
Selecting the CLIP/COLP numbers
You can inform your CLIP/COLP number (which is classified as either business use or
private use) to the other party or to the ISDN Network.
*: A 4 Extension Expansion Card (KX-TD20870) is required.
