Figure 23
OPS analog line card - jumper block locations
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. See
Table 57 "OPS analog line card - configuration" (page 134)
.
For units connected to loops of 460 to 2300 ohms, both jumper blocks
must be installed. For loops that are 460 ohms or less, jumper blocks are
not installed.
Figure 76 "Test parameters screen" (page 305)
shows the
location of the jumper blocks on the OPS analog line card.
