Procedure 34

Installing the OPS analog line card

Step

Action

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 28 "OPS analog line card

configuration" (page 203)

and

Figure 96 "OPS analog line card:

jumper block locations" (page 204)

For units connected to loops of 460 to 2300 ohms, both jumper
blocks for that unit must have jumper straps installed. For loops that
are 460 ohms or less, jumper straps are not installed.
