Notice
If the connected ISDN terminal has no external power source, make sure that the power
is supplied from the BRI1 card by programming the Hybrid IP-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 BRI1 card. Failure to do so may cause damage to
the power supply circuit of the BRI1 card or the terminal.
