Powering the Integrated Systems

Table 18 summarizes the shelf powering requirements and heat dissipation for the PG-Flex<italics 10>PG 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
The configuration used for computing the shelf current and heat dissipation includes two PMXs and one
PAU or PMU.

(*) Indicates the current when all lines are off hook with all DSL lines at maximum length with –48 Vdc battery.
(†) Indicates the recommended fuse for –42.5 Vdc battery and 15% fuse margin.
(‡) Indicates the subscriber drop set for LONG is ≤ 960 Ω.
(**) Indicates the subscriber drop set for SHORT is ≤ 830 Ω.
