User-supplied (not included): RJ45 connector

•

LINE 5 to LINE 8 are for BRI8 card only.

•

When connecting these optional service cards to the trunk, connect through an NT1; do not 
connect to the U interface of the trunk directly.

•

These optional service cards have 100 

 of terminal resistance. For use in point to multi-point 

connection, the cards must be placed at the end of the bus.

•

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.

•

For details about power failure transfer, refer to "2.12.1 Power Failure Connections".

•

To confirm the trunk connection, refer to "Confirming the Trunk Connection" in "2.13.1 Starting the 
Hybrid IP-PBX".

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.
