Notes
• In some countries/areas, the PRI30 card must not be connected to the Public Switched
Telephone Network.
• Connect these optional service cards to the trunk through an NT1; do not connect to the U
interface of the trunk directly.
• Use only 1 type of connector (RJ45 or BNC) for connection of PRI30 card; RJ45 and BNC
cannot be used simultaneously. Set the termination switch to 120 Ω (default) or 75 Ω for
connector type to be used.
• When connecting the RJ45 connector, attach the included ferrite core (except in Canada,
where the ferrite core is not necessarily required).
