configure your front function card for G.703 operation. Figure 3 shows
the Interface Driver Board connected to a Model 1092ARC front func-
tion card (You may also use this product with other Patton rack cards,
such as Model 1094ARC and 1095RC).

Follow the instructions below to connect the interface driver board
to the front function card:
1. With the function card (such as 1092ARC, shown above)
pulled out of the rack or clusterbox chassis, locate the driver
board to be replaced on the top of the base unit front card.
2. Lift the old interface board gently off of the PC board.
3. Position the IM2RC/F-128K driver board on top of the function
card's pc board with the sockets oriented toward the male
pins. Please be sure the label marked FRONT
pointed toward the front of the function card (toward the
LEDs).
4. Push the Interface Driver Board gently onto the socket and re-
