using a transformer because of the size of the RJ-11 adapter. Hang it
above or to the side of the jack and run the line and power cords to it.
Note 2: The above-mentioned transformers can also be used with
outlets identified as 110V or 220V.
Closet Power Supply
Closet power can be obtained from an AC transformer for loops of 100 ft.
(30m) or less, or a DC transformer for loop lengths of 650 ft. (198 m) or less.
An equivalent power source can be used but must be UL listed to provide
isolation of outputs to the terminal. See “Closet power supply configuration”
on page305.
