NON CODED INFORMATION AND COMPANION DATA SWITCHING MECHANISM

摘要

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
