Powering the System
summarizes the powering requirements and heat dissipation for the PSC-822 when it is fully populated with
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 for a fully populated Field Shelf under these conditions.
Table 9. PCS-822 Field Shelf Power Consumption and Heat Dissipation
The conditions in
assume that the POTS lines at all customer sites are off hook.
Each configuration assumes the use of one Management Unit and 2 MUXs (
