Abstract
For distributive services in telecommunications networks, and in particular methods for establishing point-to-multipoint connections and multipoint-to-point connections as well as methods of releasing these types of connections. Program distribution to several subscribers uses network resources in common along common call routes. A list of potential program distribution points is created and a running index is associated with each one of the distribution points. Before a connection is set up to a subscriber the list is examined and a distribution point is selected from which a point-to-point connection is set up to the subscriber. The running index is stepped up. The running index of a distribution point is stepped down during release of a connection and is examined with release of a call route section.
