1. A packet communicating system comprising:
- an optical line termination (hereinafter referred to as OLT) for subsidiarily connecting optical network units (ONU) by the passive double star type (PON), said OLT having a function for terminating the physical layer of the PON and controlling bandwidths in physical lines between the OLT and the ONU; and
a broadband access server (BAS) connected to said OLT, said BAS having a function for authorizing users communicating with the Internet, via the ONU and the OLT, wherein said BAS having a function for controlling said OLT system through a special physical line to the OLT provided in the BAS for controlling, using information of the users obtained from a RADIUS server managing information of the users when authorizing the users.

Abstract
Bandwidth control over users accommodated under ONU in PON is achieved. BAS sets user bandwidth information obtained during user authorization in OLT. The OLT achieves bandwidth control on a user basis, using bandwidth information set from the BAS. The present invention enables bandwidth control over users under the ONUs.

13. A packet communicating system comprising:
-
a plurality of optical network units;
a star coupler connected with the plural optical network units; and
a packet communicating apparatus connected with the star coupler, wherein the packet communicating apparatus multiplexes sending data to the plural optical network units and sends the multiplexed sending data to the star coupler, the star coupler broadcasts the multiplexed sending data to the optical network units, and each of the optical network units receives data directed to that optical network unit, wherein the packet communicating apparatus comprises;
an optical line termination having a function for controlling bandwidths between the optical line termination and the optical network units; and
a server, connected to the optical line termination, that has a function for authorizing users who communicate with a network via the optical network units and the optical line termination, and wherein the server uses user information used during the user authorization and the optical line termination sets bandwidths on a user basis.
