This optional service card has 100 of terminal resistance. For use of 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 "2.12.1 Starting the Hybrid IP-PBX".

Notice

If the connected ISDN terminal has no external power source, make sure that the power is supplied from the BRI2 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 BRI2 card. Failure to do so may cause damage to the power supply circuit of the BRI2 card or the terminal.
