Abstract
An optical line termination (OLT) comprises a dynamic cell allocation section, a control section, a message transmitter-receiver section and a cell allocation section. The dynamic cell allocation section sets upstream bands based on existence of an alarm and a type thereof transmitted by each optical network termination(ONT). The alarm from each ONT is detected, and a detection result detected this time, a detection result detected for the last time and the number of empty cells in the cell allocation cycle are referred to. Thus, a new band is set for each ONT. The dynamic cell allocation section computes a cell allocation for a frame with respect to three types of upstream bands for each ONT. When the band is changed, cell allocation positions corresponding to all ONTs are computed.
