Configuring the OPS analog line card 133
The line type, terminating impedance, and balance network configuration
for each unit on the card is selected by software service change entries at
the system terminal and by jumper strap settings on the card.
Jumper strap settings
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 23 "OPS analog line card - jumper block locations"
(page 135) shows the location of the jumper blocks on the OPS analog
line card.
