3.1.1 Overview

To use the ISDN Line Service, the following unit can be installed to the KX-TD816 and KX-
TD1232.
2-ISDN U-point Line Unit (KX-TD382)
4-ISDN U-point Line Unit (KX-TD384)
6-ISDN U-point Line Unit (KX-TD386)
4-ISDN S / T-point Line Unit (KX-TD284)
Primary Rate Interface ISDN Expansion Unit (KX-TD290) [KX-TD1232 Master only]
These units add ISDN U-point or S / T-point lines.
These units can be installed in any of the expansion areas provided on the front of the main unit.
The KX-TD290 adds one Primary Rate Interface (PRI) ISDN line. One PRI ISDN line adds 23
outside lines (outside lines 25 through 47) to the system. This unit can only be installed to the
KX-TD1232 Master system.
When the KX-TD290 is installed to the system, the maximum number of available outside
lines is limited to 31. In the case of System Connection, the basic and extended outside line in
the Slave system cannot be used.
Notice
• System Programming is required for card location identification. It is not possible to
connect this unit only to the slave system.
• The PLL (Phase Locked Loops) Card (KX-TD112) must be installed to the system before
the ISDN Line Unit is installed. This card is used to synchronize the system clock with the
clock of the ISDN network.
• In the System Connection of the KX-TD1232, the PLL Card can be installed to the only
master system.
• If you use the KX-TD170 with the KX-TD290, you must use the KX-TD170 which has
suffix 'C' or later.
The former KX-TD170 does not work properly with KX-TD290.
Please see the back of the unit and check suffix.
