2.7.4 First Party Call Control CTI Connection
CTI connection between a PC and a KX-T7633/T7636 DPT provides first party call control. The CTI
connection is made via a USB interface (version 2.0), and uses the TAPI 2.1 protocol.
A USB Module (KX-T7601) must be connected to the KX-T7633/T7636 DPT.
Note
The operating system of the PC required for first party call control depends on your CTI application
software. For details, refer to the manual for your CTI application software.
Notes
• The maximum length of the USB cable is 3 m.
• USB Modules must not be connected to DPTs in the Digital XDP connection. In a Digital XDP
connection, the PC cannot be used. If a USB module is connected to a slave DPT, the DPT will not
work properly.
