AC Adaptor Selection
If the Hybrid IP-PBX has BRI extension port, you need to calculate the total "load figure" from
the type and number of equipment to be connected, and determine whether or not an
additional AC adaptor needs to be connected.
Load Figure Calculation
If the connected ISDN telephone has an external power source, its load figure is "0".
AC Adaptor Capability
The following load figures can be supported.
Connected AC Adaptor
Supplied AC Adaptor only
Supplied AC Adaptor and Additional AC
If the load figure exceeds "96", it cannot be supported by the KX-TDA30. In this case, use
the KX-TDA100 with M-Type Power Supply Unit (PSU-M), or the KX-TDA200 with either
PSU-M or L-Type Power Supply Unit (PSU-L).
