2.6.3 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 Super Hybrid Port, it can also have an SLT connected in Parallel mode or XDP mode.
Notes
• Both DPTs must be KX-T7600 series DPTs (except KX-T7640). Note that the KX-T7667 can only
be connected as a slave DPT.
• 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
"1.13.2 Paralleled Telephone" and "1.5.7 Extension Port Configuration" in the Feature Manual for
further information.
