OPS Analog card installation
1 Set the jumpers on the NT1R20 OPS card.
Each line interface unit, on the card, is equipped with two jumper
blocks that are used to select the proper loop current, depending upon
loop length (Refer to Table on page 194 and Figure 80 on page 196).
For units connected to loops of 460 to 2300 ¾, both jumper blocks for
that unit must have jumper straps installed. For loops that are 460 ¾
or less, jumper straps are not installed.
