B.2 txwv tsis pub tag nrho REPLACEMENT Yog tias koj tab tom xav txog kev hloov ntawm tag nrho HPK2 thiab EMPU processors hauv Tsib/TenSlot Modules, nco ntsoov tias Lub Clock Source/Repeater board yog ib qho taw tes hauv av txuas rau LCN cable shield. Yog li ntawd, txawm tias 12.5 kHz (Subchannel) moos ua haujlwm tsis raug siv, CS / R lossis lwm yam kev siv hauv av tseem yuav tsum tau muaj ntawm txhua ntu coax. Dual Node Modules tuaj yeem txuas tau los muab cov ntsiab lus hauv ib qho tsis tas yuav tsum muaj CS / R. Saib Dual Node Module Service hauv daim ntawv no. Yog tias tsis muaj Dual Node Modules ntawm ntu coax los muab cov av ntawd, ces tag nrho cov kev hloov pauv tuaj yeem ua tiav los ntawm kev hloov ob lub Tsib-Slot Modules nrog ob Dual Node Modules. B.3 YUAV TSUM TSEEM CEEB Lub kaw lus yuav tsum tau nce thiab khiav ntawm Software Release 320 lossis tom qab ua ntej ua qhov hloov pauv processor. Koj yuav tsum muaj daim npav LCN I / O ntawm kev kho dua T lossis tom qab (txawm yog nyob rau hauv module lossis hauv cov khoom seem). Yog tias daim npav hauv koj qhov module yog LCNFL, nws (lossis ib qho ntawm cov khoom seem) yuav tsum yog qhov hloov kho F (lossis tom qab). B.4 NODE APPLICABILITY Kuaj xyuas tias qhov hloov K2LCN muaj feem xyuam rau lub hom phiaj: 1. Pom tseeb tias tsis muaj Lub Clock Source/Repeater (CS/R) board nyob tom qab ntawm lub module. Yog tias muaj CS / R pawg thawj coj saib thiab yog tias tsim nyog los hloov lub rooj tsav xwm processor hauv node, hloov nws nrog tib hom processor board. Tau txais tib hom processor board los ntawm cov khoom seem los yog los ntawm lwm qhov ntawm lub network. Yog tias koj tshem lub processor los ntawm lwm qhov, hloov nws nrog K2LCN rau txoj haujlwm no. Nco ntsoov, txawm li cas los xij, tias lub cim xeeb thiab lwm yam kev xav tau ntawm cov txheej txheem no tau ua tiav. 2. Xyuas kom paub tseeb tias tus processor yuav hloov tsis yog HMPU (lub HMPU hloov tsis tau los ntawm K2LCN). 3. Rau kev ua tau zoo sib xws, processor board hom nyob rau hauv redundant node khub yuav tsum tsis txhob tov. Yog tias koj yuav tsum hloov lub rooj tsav xwm txheej txheem thiab qhov cuam tshuam ntawm qhov yog ib qho ntawm cov khub tsis sib xws, K2LCN processor board yuav tsum tau nruab rau hauv nws tus khub. Saib tshooj B.6 hauv qab no. B.5 MEMORY SIZE Txiav txim seb tus nqi ntawm lub cim xeeb nyob rau hauv lub node, nrog rau tag nrho cov nco boards thiab ib tug nco ntawm lub processor board yuav tsum tau hloov. Kev hloov K2LCN yuav tsum muaj tsawg kawg qhov no nco ntau. Muaj kev nco ntau tsis yog teeb meem. Vim tias K2LCN pawg thawj coj saib muaj ntau qhov sib txawv, xyuas kom koj txhim kho qhov loj me los ntawm kev sib piv cov tab (peb tus lej kawg) ntawm tus lej ntawm koj lub rooj tsavxwm nrog cov lus hauv qab no: 51401551-200 = 2 megawords 51401551-400 = 4 megawords 51301. 51401551-600 = 6 megawords
