1. The MFM has its own wall power unit located at the telephone and therefore is not added to the unit
load calculation.
2. Up to two DSSs (one DSS per MLX-28D or MLX-20L console) can be powered from each control
unit carrier. For example, a 3-carrier system can have 6 system operator positions, each with one
DSS powered from the control unit.
If the total actual unit load is less than or equal to 54, any power supply
module is sufficient.
If the total actual unit load is greater than 54, continue to Step 7.
7. Try to exchange modules between carriers to reduce the unit loads to
54. (Remember that the 100D, 400 (LS), 400 GS/LS/TTR, 800 GS/LS-ID,
800, 800 NI-BRI, and 800 GS/LS modules have unit loads of 0.0.)
Repeat Steps 1 through 6 to recalculate unit loads for the new
configuration.
If the exchange reduces the unit load to 54 or less, any power
supply module is sufficient.
If the exchange does not reduce the unit load to 54 or less, a
391A3 power supply is needed. Continue to Step 8.
