CAUTION
•
If the connected ISDN terminal has no external power source, make sure that the power is supplied
from the BRI4/BRI8 card by programming the PBX accordingly.
However, if there is an external power source to the terminal, make sure that there is no power supplied
to the terminal from the BRI4/BRI8 card. Failure to do so may cause damage to the power supply circuit
of the BRI4/BRI8 card or the terminal.
