Abstract: Disclosed are a coated concrete substrate and a process for coating the substrate. The process includes applying a colored polymer-enhanced grout coating and allowing it to cure. A template without adhesive backing is applied over the coating layer. The template is removed after the coating layer is cured. A primer is applied over the coating layer, for providing good cohesive and adhesive properties. A sealer is applied over the cured primer layer, for providing chemical resistance and UV protection. The resulted coated concrete surface is decorative, durable, resilient, stain, chemical resisting, UV protecting, and has the appearance of brick or ceramic tile.

Abstract: Charging details are produced for customers in response to their use of telecommunications services. Details of call items for a customer are compiled and a plurality of call types (73, 75, 77) are defined. Each call item is identified as belonging to one of these call types and a notional charge is calculated for each item. Notional charges for each item are accumulated and call categories are defined, wherein at least one of said call categories has a discount rate associated therewith. Accumulated call type values are then mapped onto category accumulators in response to customer reference data.
