Description
上記課題を解決するために、本発明のある態様のPONシステムは、冗長に設けられた運用系光回線ユニットと予備系光回線ユニットを備える局側装置と、局側装置と通信を行う加入者側装置と、を備えるPONシステムであって、運用系光回線ユニットから予備系光回線ユニットへの冗長切替処理が行われる前に、予備系光回線ユニットと加入者側装置との間の接続の正常性が確立され、前記予備系光回線ユニットと前記加入者側装置との間で擬似的にGATEフレームとREPORTフレームのやりとりを行うことで、前記予備系光回線ユニットと前記加入者側装置との間の接続の正常性が確認される。 In order to solve the above-described problems, a PON system according to an aspect of the present invention includes a station-side device including redundant operation-system optical line units and standby-system optical line units, and a subscriber communicating with the station-side apparatus. A PON system including a side device, and before the redundant switching process from the active optical line unit to the standby optical line unit is performed, the connection between the standby optical line unit and the subscriber side device is performed. Normality is established, and the standby optical line unit and the subscriber side apparatus are exchanged between the standby optical line unit and the subscriber side apparatus in a pseudo manner by exchanging GATE frames and REPORT frames. normality of the connection between the Ru is confirmed.
本発明の別の態様は、局側装置である。この装置は、冗長に設けられた運用系光回線ユニットと予備系光回線ユニットを備え、加入者側装置と通信可能に構成された局側装置であって、運用系光回線ユニットから予備系光回線ユニットへの冗長切替処理が行われる前に、予備系光回線ユニットと加入者側装置との間の接続の正常性が確立され、前記予備系光回線ユニットと前記加入者側装置との間で擬似的にGATEフレームとREPORTフレームのやりとりを行うことで、前記予備系光回線ユニットと前記加入者側装置との間の接続の正常性が確認される。 Another aspect of the present invention is a station-side device. This apparatus is a station-side apparatus that includes a redundant operation system optical line unit and a standby system optical line unit, and is configured to be able to communicate with a subscriber side apparatus. before the redundancy switching process to the line units is carried out, the normality is establishing the connection between the protection optical line unit and the subscriber unit, between the subscriber units and the protection optical line unit in by performing the pseudo exchange of GATE frame and REPORT frame, the normality of the connection between the protection optical line unit and the subscriber unit Ru is confirmed.
本発明のさらに別の態様は、冗長切替方法である。この方法は、加入者側装置と通信可能に構成された局側装置における運用系光回線ユニットから予備系光回線ユニットへの冗長切替方法であって、運用系光回線ユニットから予備系光回線ユニットへの冗長切替処理が行われる前に、予備系光回線ユニットと加入者側装置との間の接続の正常性を確立し、前記予備系光回線ユニットと前記加入者側装置との間で擬似的にGATEフレームとREPORTフレームのやりとりを行うことで、前記予備系光回線ユニットと前記加入者側装置との間の接続の正常性を確認する。
Yet another aspect of the present invention is a redundancy switching method. This method is a redundant switching method from an active optical line unit to a standby optical line unit in a station side apparatus configured to be able to communicate with a subscriber side apparatus, and the active optical line unit to the standby optical line unit. Before the redundancy switching process is performed, the normality of the connection between the standby optical line unit and the subscriber side apparatus is established, and the standby optical line unit and the subscriber side apparatus are simulated. The normality of the connection between the backup optical line unit and the subscriber side device is confirmed by exchanging the GATE frame and the REPORT frame .
