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).
