Abstract
Mechanism for 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 arrange the bit stream to be sent into a format of regularly occurring time slots separated by flags. The data only containing time slots begin with a first flag (F2), the NCI only containing and NCI and data containing time slots begin with a second flag (F1) and inside these slots, 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 are switched using high speed bus 26 and the data portions are routed using the normal data paths.
