This section discusses HLU-200 List 1A operations when used without
doublers. Nondoubler HLU-200 current drains on the two CBA power
supplies, power consumption and dissipation are listed in

Power Dissipation
(1) CPE-I = Customer Premises Equipment current
The maximum power dissipation measures the power converted into heat
inside the unit. It contributes to the total heat generated in the space around
the unit.
The maximum power consumption is the total power that the HLU draws
from the CBA power buses. This parameter is needed when the
Litespan-2000 is battery powered. It determines the battery capacity required
to maintain an 8-hour, standby battery reserve for emergencies.
The HLU line power supply converts the -48 Vdc battery output to -130 Vdc
(-200 Vdc for doublers), which provides a simplex power feed on the two
HDSL line interfaces.
