[DPT + DPT]
• Available Telephones
KX-T7600 series (except KX-T7640)
• KX-TDA30/KX-TDA100/KX-TDA200 only
Digital XDP connection enables the maximum number of DPTs that the PBX supports to
be increased. This increase is only available when (1) the MEC card is installed and (2) a
high-capacity power supply unit (with the KX-TDA100/KX-TDA200) is installed or an
additional AC adaptor (with the KX-TDA30) is connected.
• KX-TDA15 only
Digital XDP connection is available only for a DPT that is connected to a Super Hybrid
port.
• When using Digital XDP connection, the following features cannot be used with the DPTs:
a) OHCA: A call waiting tone will be heard even if the OHCA feature is set.
b) USB Module: The DPTs will not work correctly if a USB Module is connected. Do not
connect USB Modules to the DPTs.
Note
Even if the slave DPT is disconnected, the OHCA feature and USB Module still cannot be
used with the master DPT. To use them, the DPT must be disconnected from the PBX, and
then reconnected.
[DPT + DPT + SLT]
• When an SLT is connected to the slave DPT in parallel mode, the SLT works as the parallel
extension of the master DPT.
