To use the ExpressCard, you plug it into the 3G ExpressCard slot, enabling you to dial a
wireless call to the 3G wireless service provider network, which acts as an Internet
gateway.
To use the 3G ExpressCard as a backup interface, you can use the dialer feature available
in the services gateway.
For more information on configuring the 3G ExpressCard, see the
JUNOS Software
Interfaces and Routing Configuration Guide.
NOTE:
The J-SRX210 Services Gateway does not support hot insertion and removal of
the 3G ExpressCard.

service provider populates this SIM with the subscriber service parameters.

Interface support — The ExpressCard interface supports the IP over PPP interface from
the network through the wireless link.

the ExpressCard, such as type, version, wireless status, and user profiles.
