Ubalo lokuqalaus (O1)
II-ONUkwesi simo sisanda kuqaliswa kwaye sise-LOS / LOF. Emva kokuba umsinga osezantsi ufunyenwe, i-LOS kunye ne-LOF ziyapheliswa, kwayeI-ONUiqhubela kwimo yokulinda (O2).
Ubalo olulindileyous(O2)
II-ONUyale meko ifumene ezantsi, ilindele ukufumana iparameters zenethiwekhi.Xa iI-ONUifumana umyalezo we-Upstream_Overhead, yenza ulungelelwaniso olufanelekileyo (umz., uphawu lokucanda, imodi yamandla, ukulibaziseka kwe-preset equilibrium) kunye nokutshintshela kwi-serial number status (O3).
Ubume beNombolo yothotho (O3)
IOLTithumela uthotho-Inombolo yemiyalezo yesicelo kuzo zonkeI-ONUkweso simo ukufumana entshaI-ONUkwakunye nenombolo yabo yothotho.Xa iOLTufumana entshaI-ONU, iI-ONUilindele iOLTukuyinika iI-ONU-ID.OLTDlulisa ngapha koKwabela_ONU-ID umyalezo ubhekisa kumdlalo we-ONU-ID.EmvaI-ONUufumanaI-ONU-ID, idlulisela kwimo esukelayo (O4).
Ri-anging status (O4)
EyahlukileyoI-ONUukuthumela imiqondiso kufuneka bahlale ngaxeshanye xa befikelela kwiOLT, ukuze ngamnyeI-ONUidinga ukulibaziseka kolungelelwaniso, kwaye le parameter ilinganiselwa kwisimo sokusukelaI-ONUifumana iRangi_Time umyalezo kwaye ihambe iye kwimeko yokusebenza (O5).
Ubume bokuqhuba (O5)
II-ONUkwesi simo sinokuthumela idatha ye-uplink kunye nemiyalezo ye-PLOAM phantsi kolawulo lweOLT, kwaye iI-ONUkule meko nako ukuseka ezinye imidibaniso njengoko kufunwa.Xa uluhlu luphumelele, zonkeI-ONUzithunyelwa ngokweequilibrium yazo ixesha lokulibaziseka uphawu ukugcina isakhelo uplink synchronized.Imiqondiso ithunyelwe ngokwahlukeneyoI-ONUiya kufikelela kwiOLTngokwahlukeneyo, kodwa uphawu ngalunye luvela kanye apho lufanele ukuvela khona kwisakhelo se-uplink.Misa iI-ONUisebenza: Ngexesha lokusebenza okuqhelekileyo, iOLTinokubangela iI-ONUukumisa umqondiso ukufumana inombolo yesiriyali yenyeI-ONUokanye umgama omnyeI-ONU.OLTiyayeka ukunika ilayisenisi yonke i-uplink bandwidth ixesha,I-ONUisebenza ngendlela eqhelekileyo, kwaye ayifumani gunya, idala ixesha elizolileyo, ngokoOLTibangela zonkeI-ONUukumisa umqondiso.
Isimo se popup (O6)
Esi simo singeniswa xa iI-ONUkwimeko yokusebenza (O5) ibona i-LOS okanye i-LOF.Kule meko, iI-ONUngoko nangoko uyeke ukuthumela umqondiso, ukuze iOLTiyakubona i-alam ye- LOS yeI-ONU.Xa i-ODN fiber iphazamiseka, ezininziI-ONUizakungena kwesi simo, ithathela ingqalelo ukuthembeka komsebenzi womnatha, ngenye yezi ndlela zilandelayo:
Ukuba inversion yokhuseleko yenziwe, zonkeI-ONUiya kuguqula ifayibha yogcino.Kweli nqanaba, zonkeI-ONUiya kuphinda iphinde, kwaye okuOLTithumela umyalezo we-POPUP yoSasazo ukwazisa bonkeI-ONUukungenisa ubume boluhlu (O4).
Ukuba akukho inversion yokukhusela kodwaI-ONUinamandla okhuseleko lwangaphakathi, iOLTithumela umyalezo oLathisiweyo we POPUP ukwazisa iI-ONUukufaka imo yokusebenza (O5).Xa iI-ONUingena kwimo ye O5, iOLTkufuneka ukubona iI-ONUkuqala kwaye emva koko Buyisela ishishini leI-ONU.Ukuba iI-ONUayibuyiseli kwi-LOS okanye i-LOF, iI-ONUayizukufumana umyalezo woSasazo lwePOPUP okanye umyalezo oKhokelwe kwi-POPUP, kwaye emva kwexesha le-TO2, iI-ONUingena kwimo yokuqala (O1).
I-Emergency Stop State (O7)
Xa iI-ONUifumana i Khubaza_Inombolo_ yomyalezo weNombolo ngokhetho "Khubaza", iI-ONUingena kwimeko yokuyeka likaxakeka (O7) kwaye icime i-laser.Kwilizwe le-O7, iI-ONUakuvumelekanga ukuthumela imiqondiso.Ukuba iI-ONUayingeni ngempumelelo i-O7 karhulumente, kunye neOLTingaqhubeka ukufumana imiqondiso evela kwiI-ONU, iOLTyenza i-alamu ye-Dfi.Xa iI-ONUiyasilela, iOLTithumela i Khubaza_Inombolo_ yomyalezo weNombolo ngeVumela ” ukhetho lokuvulaI-ONU.I-ONUifumana umyalezo kwaye ingenise imo yokulinda (O2) kwaye zonke iiparamitha (kubandakanya inombolo yothotho kunye ne-ONU-ID) zitshekishwa kwakhona.
