Data communications connections between interactive terminals and host computers generally exhibit long holding times, while the data density of the transmissions is sparse. The circuit switch of a switching system is an inefficient and expensive medium for this type of communication. Thus, the subject switching system uses a packet switch connected in parallel with the circuit switch to handle bursty data traffic from interactive terminals. A routing bit is set in the data stream from each port circuit to indicate the nature of the transmission and this transmission is then routed to the packet switch if it is a bursty data transmissions while voice messages are routed to the circuit switch.
