Abstract

A service-on-demand system (SYS) includes a facility (EIN) which is designed to assign transmission channels to terminals (END1, END2). To accomplish this, the facility (EIN) contains two interfaces (S1, S2) for connecting it to two groups of terminals (END1, END2), a memory (MEMO) which holds an assignment table containing entries on currently available and currently busy transmission channels for transmitting services requested from terminals (END1, END2), with a variable assignment of transmission channels to terminals (END1, END2) being possible regardless of which group the terminals (END1, END2) belong to, and a control unit (CTRL) which coordinates the assignment. Only those transmission channels can be assigned which are considered currently available in the memory (MEMO). The transmission channels are not permanently assigned to groups but are largely freely available to all terminals (END1, END2). For example, a minimum number of freely available transmission channels may be reserved for each group, and the remaining channels may be used both by terminals of group 1 and by terminals of group 2, etc., depending on traffic volume and demand. This provides flexibility and adapts the assignment of transmission channels automatically to the traffic volume.
