摘要： In the bandwidth-allocating method of the present invention for PON (: Passive Optical Network), a bandwidth is allocated from an optical line terminal to each optical network unit. The optical line terminal stores a bandwidth contract table for indicating a correspondence relationship between communication flow IDs and service quality parameters, each communication flow ID identifying each communication flow between the optical line terminal and each optical network unit. The bandwidth-allocating method includes a step of transmitting a service-quality request message including the communication flow IDs and the service quality parameters from each optical network unit to the optical line terminal, and a step of the optical line terminal's updating the bandwidth contract table based on the service quality parameters, and performing the bandwidth allocation to a communication flow specified by the corresponding communication flow ID based on the bandwidth contract table.

摘要： There is a need to provide a multirate burst mode receiver for an OLT to be capable of receiving a high-speed burst signal without the need for a special capability of an ONU in a PON system including a mix of ONUs at different transmission bit rates. A multirate burst mode receiver according to the invention includes a signal input discrimination section and a bit rate discrimination section. The signal input discrimination section detects an average amplitude to discriminate signal input. The bit rate discrimination section detects an envelope curve for a high-frequency component to discriminate a signal bit rate. Based on a discrimination result from the signal input discrimination section and the bit rate discrimination section, the multirate burst mode receiver switches a setting for an optical signal reception section and a serial-parallel converter corresponding to the reception bit rate.

摘要： A passive optical network (PON) system includes at least one optical line terminal (OLT), a plurality of optical network units (ONUs) connected to each OLT, and an OLT management server used to manage the OLT. The OLT management server creates a VLAN access control table in response to a user's request to indicate a VID translation relation among different VLAN identifiers (VIDs) and sends a VID translation relation described in the VLAN access control table to the OLT, and the OLT creates a VLAN translation table indicating a correspondence relation between a source VID and a destination VID, which are waiting for translation, based on the received VID translation relation. If the OLT determines that a VID included in a received frame must be translated based on the VLAN translation table, the OLT references the VLAN translation table to translate the VID included in the received frame to a corresponding destination VID.

摘要： When the number of DUTs carried on a loader buffer and scheduled to be held by contact arms at the next test is less than N, a DUT at a contact arm corresponding to a missing position at the loader buffer among the N number of DUTs being held for execution of a current test is held as it is without being ejected. While holding this DUT, the DUTs carried at the loader buffer for execution of the next test are picked up and the test is executed in that state.

摘要： A method and an apparatus for implementing a storage function in a passive optical network (PON) system. On the basis of a LINK ID held by the data, data requiring storage, e.g. data making exclusive use of a wide bandwidth such as audiovisual data and large-volume data packages, are determined among all the data sent to an optical network unit. These data requiring storage are stored in a storage device installed in the optical network unit. In case the user requests data stored in the storage device, the stored data are transferred directly to the user, without any need to request and send these data for the second time via an IPTV server and the core network. It is possible to avoid duplicate transfers of data, and in particular to avoid duplicate transfers of data making exclusive use of a comparatively wide bandwidth such as audiovisual data and large-volume data packages, to improve the utilization factor of the downlink bandwidth, and to reduce flow congestion and data delays.
