The evidence of a growing revenue that is generated from these investments (installation fees, monthly fees, incoming calls, inherent promotion of Portugal Telecom's services) was absent, as was the new technology used to implement the USO in a more cost-efficient manner.
For Portugal the question is about the speed of rebalancing. Owing to the limits of the proposed price cap regime, Portugal claims that Portugal Telecom needs about five years to implement decreases in long-distance and international call charges and increases of installation and monthly rental charges, i.e. from 1996 to 2000.
