Abstract:
1. An optical line terminal (OLT) of a passive optical network (PON), comprising: a frame monitoring unit configured to monitor upstream frame data received for each transmission container (T-CONT); an error detection unit configured to determine whether a queue report error is generated for each T-CONT according to a result of the monitoring; and a band allocation controller configured to allocate an upstream band for an optical network unit (ONU) that generates the queue report error, wherein the band allocation controller includes a normal ONU band allocation unit that processes the band allocation for the normal ONU, an abnormal ONU band allocation unit, and a processor configured to control so that the abnormal ONU band allocation unit processes the band allocation for the ONU in which the queue report error is generated, by using information received from the error detection unit.
