4.8.3 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-DT500/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
"15.1.2 Paralleled Telephone" and "6.1.11 Extension Port Configuration" in the Feature Manual for
further information.
