Packet communications customer-station apparatus 

A packet communications apparatus which can selectively generate a desired packet signal in response to a transmission permission received from an intranet apparatus is provided. The apparatus includes an access control circuit for receiving a transmission permission signal from the intranet apparatus and generating a transmission command signal to instruct the transmission of the packet signal to a multiplexing circuit to each of a plurality of line units on the basis of the transmission permission signal. Each line unit includes a transmission control circuit for controlling so as to store each packet signal into a buffer on the basis of a header information and transmit the packet signal from the buffer to the multiplexing circuit on the basis of the received transmission command signal. Further, the packet signals including the same identification information are stored into the buffer as one packet signal group. The packet signals are supplied from the buffer to the multiplexing circuit on the basis of the received transmission command signal and identification information.
