Notes
• When connecting this optional service card to the trunk, connect through an NT1; do not connect
to the U interface of the trunk directly.
• This optional service card has 100 Ω of terminal resistance. For use in point to multi-point
connection, the card must be placed at the end of the bus.
• This optional service card can be used for either trunk or extension connection, by setting the A/B
switch or using the connector with appropriate pin assignments.
• To confirm the trunk connection, refer to "Confirming the Trunk Connection" in "2.10.1 Starting the

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.
