Abstract
The invention relates to a mechanism to be used in an integrated packet/circuit switched telecommunication network. It allows instantaneously on a per slot basis, the re-allocation of unused bandwidth left by a circuit user source to the background packet flow, and allows giving it back to the circuit source as it resumes its activity. The circuit user data Cd are sent through the network during slots of frames which are assigned to the circuit users on a per- call basis. Interfacing means (30, 32) are provided to generate slot qualifying bits Caq which are set to a first value when the corresponding circuit users are active and to a second value when the corresponding cirucit users are inactive. These qualifying bits are transported through the network in correspondence with the slot they qualify and sensed to cause the slots having a Caq set to the second value to be filled with packet bits.
