Claim:
1. A relay device comprising: a first transmitting and receiving unit that performs transmission and reception of signals to/from an upper-level first line; a second transmitting and receiving unit that performs transmission and reception of signals to/from a lower-level second line; a relay processing unit that relays a downstream frame received by the first transmitting and receiving unit to the second transmitting and receiving unit, and relays an upstream frame received by the second transmitting and receiving unit to the first transmitting and receiving unit; and a processor for a control unit that follows upstream multiple access control performed by a station side device in the first line, for transmission of the upstream frame to be transmitted by the first transmitting and receiving unit to the station side device, and independently performs upstream multiple access control for reception of the upstream frame received by the second transmitting and receiving unit from a home side device in the second line, wherein the control unit reports an amount of data that the home side device in the second line is or will be allowed to transmit, to the station side device in the first line before the data arrives at the second transmitting and receiving unit.
