3.8.3 Digital EXtra Device Port (Digital XDP) Connection
A DPT can be connected to another DPT on the Digital XDP connection. In addition, if the DPT is connected
to a DHLC4 card, it can also have an SLT connected in Parallel mode or XDP mode.
Note
•Both DPTs must be KX-DT300/KX-T7600 series DPTs (except KX-T7640). Note that the KX-T7667
can only be connected as a slave DPT.
•Bluetooth® Modules or USB Modules must not be connected to DPTs in the Digital XDP connection.
•Parallel mode or XDP mode can be selected through system programming.
•If XDP mode is enabled through system programming, parallel connection is not possible. Refer to
"13.1.2 Paralleled Telephone" and "5.1.7 Extension Port Configuration" in the Feature Manual for
further information.
