PCS-719 List 1A
Powering the Integrated Systems
summarizes the shelf powering requirements and heat dissipation for the PG-Flex
Plus
COT shelf when it
is fully populated with services, a battery voltage of –48.0 V, and with all CO to RT distances at their maximum
DSL reach. The table provides the average current drawn from a fully populated shelf under the these conditions.
.
The conditions in
assume that the POTS lines at all customer sites are off hook.
The configuration used for computing the shelf current and heat dissipation includes two PMXs
and one PAU or PMU.
