User terminals (4, 5) are connected to a telecommunication system, with a control system (3) operating to set up, release and/or modify connections between the terminals. Many operating functions are common to both short-term, flexibly dynamic connections and long-term, semi-permanent connections. - Connection control may be initiated from any user terminal. Controlling data may be stored in different types of storage resources in the system, e.g. volatile memories (20, 21) or a permanent, persistent memory (24). Different types of resource carry different degs. of reliability. |
