Final answer:
Cost-of-service pricing does not involve pricing services at the highest levels the markets will bear.

However, the characteristic that is NOT associated with cost-of-service pricing is option 4) Carriers price their services at the highest levels the markets will bear. Instead, cost-of-service pricing aims to cover costs and make a reasonable profit, rather than charging the highest possible price.
