Abstract
The band management circuit of the present invention is utilized in a fiber-optic network that uses, for example, ATM-PDS, in order for an SLT to control the transmissions of a plurality of ONU, which are accommodated by this SLT. The band management circuit of the present invention stores one time in a table an identification number, which specifies a multi-point device for which transmission is authorized. An identification number stored in a table is generated by a table generating portion. The table generating portion sequentially generates the identification number of a number of transmission authorizations determined in accordance with a transmission band provided to respective multi-point devices. A write/read control portion sequentially writes to a table identification number data generated by the table generating portion. In addition, the write/read control portion reads an identification number from a table in accordance with the transmission timing of an ATM cell in which an identification number is to be stored. Outputting an identification number after aligning it one time in a table enables the size and complexity of the circuit to be held in check, and makes it poss…
