Unit Load Calculation Worksheet
9. Try to exchange modules between carriers to reduce the unit loads for
slots five and six through 27. (Remember that the 100D, 400, 400
GS/LS/TTR, 800 GS/LS-lD, 800, and 800 GS/LS modules have unit loads
of 0.0, ) Repeat Steps 1 through 8 to recalculate unit loads for new
configuration.
If the exchange reduces the unit load for slots five and six through
27 or less, auxiliary power is sufficient.
If the exchange does not reduce the unit loads for slots 5 and 6
through 27, install wall power units for the appropriate number of
telephones to reduce the unit load to 27.
NOTE:
Empty slots are not permitted between modules.
