Function

Accessory and User-supplied Items

Accessory (included): Ferrite core(s) × 1 (BRI4 card) or 2 (BRI8 card)

User-supplied (not included): RJ45 connector

Notes

• 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".

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.
