9.8 Power consumption factor
The Power Consumption Factor (PCF) of contribution
units connected to a CCU has a bearing on the total
number of such units that can be connected. The 'max-
imum number of units' figure quoted for a CCU is
based on all units having a PCF of 1. This means that,
for example, a CCU which can accommodate 60 units
of PCF 1 can also accommodate 120 units of PCF 0.5.
PCFs for DCN contribution equipment are given
