Abstract: Method for controlling a vacuum sewage system for a building or for a marine vessel, which includes a vacuum unit (11), vacuum piping (7), a source of sewage (91, 92, 93, 94), and a discharge valve (8) between each source of sewage and the vacuum piping, wherein the vacuum unit generates a predetermined vacuum level in the vacuum piping, in which method the operation of the vacuum sewage system is monitored. In order to ensure an efficiently operating vacuum sewage system, the running time of the vacuum unit is monitored and the vacuum level of the vacuum piping is monitored.

Abstract: The system of generating presentation of network capacity and price collects from various sources information about communication capabilities and prices, processes this information and stores the processed information on a storage medium. In response to a local or remote user's request, a piece of the processed information is retrieved from the storage medium and transmitted as a presentation to the user's computer for displaying on the user's display device. Preferably, processed information is displayed on a map, in charts, and/or in tables. Additional data not shown immediately on the screen is also sent. This data or some items of it is displayed only in response to the user's selection. The map with the processed information and the additional information enables the user to do various analyses relating to network capacity being offered and based on the analyses the user can select an offer.
