Abstract: Mechanism allowing data and packetized non coded information NCI such as packetized voice or images, to be exchanged between workstations connected to nodes of a communication network. The workstations (18) comprise means for arranging the bit stream to be sent into a format which comprises regular slots separated by flags. The data only slots begins with a first flag (F2), the NCI only and NCI-data slots begins with a second flag (F1) and inside the slot, flag F2 separates the NCI and data portions. The route between two workstations is established by a data session using the node resources. Once a route is established, the NCI portions of the bit stream is switched using high speed bus 26 and the data portions are routed using the normal data paths. Figure 1 FR 9 84 015
