Sealing Current Jumpers
You also must set the following jumpers on the BRI-SC U*8 Card for the proper sealing
current on its individual ports (15 mA or 7.5 mA). All cards are shipped with 15 mA as the
default (jumpers closed). To change a port to 7.5 mA, remove the shorting jumpers across the
pins labeled J102 to J802 on both sets of pins next to the front edge of the card, as shown in
Figure 5-3. In these numbers, the first digit (e.g., 102) is the port number indicator.
The ports can be set individually for 7.5 mA but, once set, remain in that setting until the
jumpers are reattached. If jumpers are added then the ports are set to 15 mA.
