•When connecting the RJ45 connector, attach the included ferrite core. Refer to "2.2.9 Attaching a Ferrite Core".

•These optional service cards 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 "2.13.1 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 BRI4/BRI8 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 BRI4/BRI8 card. Failure to do so may cause damage to the power supply circuit of the BRI4/BRI8 card or the terminal.
