E3-ATM card
Connecting an E3-ATM slot card to the WAN
Use two 75-ohm coaxial cables to connect an E3 line to an E3-ATM slot card’s LINE RX and
LINE TX ports.
Inform your service provider that the equipment is connected so the provider can activate the
line.
Connecting redundant E3-ATM slot cards
You can install two E3-ATM slot cards to provide redundancy. If the primary card either fails
to boot up or is in a fault state, the secondary slot card takes over.
For information about
configuring a redundant connection, see the APX 8000/MAX TNT/DSLTNT Physical Interface
Configuration Guide.
Figure A-9 illustrates a redundant connection.
