Use two 75-ohm coaxial cables (RG 59/U) to connect the T3 line to the LINE RX and LINE
TX ports on the DS3-ATM card.
Inform your service provider that the equipment is connected, so the provider can activate the
line.

You can install two DS3-ATM cards to provide redundancy. After installing the cards,
configure line profiles for each card as explained in the APX 8000/MAX TNT/DSLTNT
