2.7.3 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 DHLC8 card, it can also have an SLT connected in Parallel mode or XDP mode.
Notes
• Both DPTs must be KX-T7600 series DPTs (excluding KX-T7640).
• 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
"1.10.9 Parallelled Telephone" and "2.1.1 Extension Port Configuration" in the Feature Guide for
further information.
