<p>PURPOSE:To improve the packet transfer capability by using a packet processor to implement protocol processing of a packet and implementing the packet transfer between a terminal accommodation equipment and the packet processor via a packet highway controller and a packet switch or the like. CONSTITUTION:Packet processing such as a B-channel or the like is implemented by a packet processor 12 controlled by the time division switch 11 of a line exchanging section. Then B-channel packet transfer is implemented by a packet switch 15 and a packet highway 14 via a packet highway controller 16 connected directly to a terminal accommodation equipment 18 and the unit 12. An incoming number translation and path selection to a packet call are similarly processed in a lump by the exchange controller 20 in the case of the line exchange. The processing is similar to a D channel, the packet transfer capability is improved more than the case of multiplex transfer.</p> |
