HRU-402 List 2
Rear Panel
The HRU-402 List 2 has four user options that must be set before you install
the unit into a shelf or enclosure. Two of these options, DS1 Receive Level
and TLOS, are located on the front panel. The other two, Sealing Current
(SCURR) and Local Power (LPWR), are located at the back of the printed
circuit board adjacent to the card-edge connector as shown in
. For
the sealing current option, you can choose to either disable or enable the
current flow over the HDSL pairs (see
). For the Local Power option,
you can choose to either force the HRU to use local power or line power.
