Tsis siv neeg xov tooj sib hloov (PBX) yog cov khoom siv los ntawm txoj kev hu xov tooj sib kis tau ntawm ob lossis ntau lub xov tooj tsis siv neeg. Ntawm cov niaj hnub hloov xov tooj tsis siv neeg, digital thiab analog hom khoom siv tau nrov tshaj plaws. Lawv txhua tus nyias muaj nyias qhov tshwj xeeb, qhov zoo thiab qhov tsis zoo uas yuav tsum tau txiav txim siab thaum yuav khoom.
Lub ntsiab sib txawv ntawm analog thiab digital PBX
Analog PBXs tuaj yeem hloov kho kev hais lus rau hauv lub cim hluav taws xob los yog hluav taws xob txuas. Lub peev xwm tseem ceeb ntawm cov khoom siv yog: intercom, pulse tone dialing, hu xov tooj tuav, hloov hloov xov tooj, tus lej kawg hloov dua tshiab, sablaj xov tooj, tau txais kev hu los ntawm lwm tus neeg siv, hnub / hmo haujlwm, paging. Analog PBXs yog qhov ntseeg tau thiab siv tau yooj yim. Cov cuab yeej zoo li no tuaj yeem siv yog tias cov kev cai siab tsis yog siv rau kev ua haujlwm ntawm lub network, thiab tus naj npawb ntawm cov neeg rau npe yuav tsum tsis ntau tshaj 50. Txhim kho qhov system ntawd hauv tuam txhab me yuav yog qhov zoo tshaj plaws. Piv nrog rau PBXs digital, cov khoom siv sib txuas yog pheej yig dua. Qhov tsis zoo ntawm analog PBXs yog qhov ntau dua me me ntawm lub luag haujlwm, txoj haujlwm system ua haujlwm nruj heev thiab tsis tuaj yeem hloov pauv.
Tsis zoo li analogue digital sib pauv, lawv tuaj yeem hloov kho kev hais lus siv cov qauv ntawm cov qauv ntawm mem tes-code tes rau hauv kwj ntawm cov binary pulses. Lawv muaj tus naj npawb ntawm cov haujlwm tseem ceeb; ob qho tib si xov tooj digital thiab digital yuav txuas nrog lawv. Nws yog qhov tsim nyog los txuas cov khoom siv ntawm ob-xaim xaim ua cov kab. Cov xov tooj digital hloov pauv, hauv kev sib piv rau cov sawv daws pom, yog cov kim dua. Lawv sib txawv hauv qhov hloov tau yooj yim ntawm lub kaw lus thiab cov phiaj xwm phiaj xwm, thiab muaj cov kev xav tau sib txawv ntawm cov thev naus laus zis ntau lawm. Qhov ua tau zoo tshaj plaws yog kev siv cov kev sib hloov xov tooj hluav taws xob zoo li no thaum lub xov tooj ntawm cov neeg yuav khoom yog ntau tshaj 50.
Cov yam ntxwv ntawm digital PBX
Qhov zoo ntawm cov xov tooj hluav taws xob tsis siv neeg suav nrog kev ntseeg siab, hloov pauv lub cajmeem (piv txwv, LCR), kev sib txuas lus microcellular. Lawv muab cov lus zoo zoo, muaj peev xwm tsim lub chaw hu. Kev siv xov tooj digital hloov pauv xov tooj ua rau nws muaj peev xwm txuas cov kab ke kaw lus (txog li ob lub khoom siv), txhim kho xov tooj sib tham, thiab koom ua ke nrog khoos phis tawj. Nrog nws cov kev pab, koj tuaj yeem ua haujlwm nrog kab xov tooj digital BRI thiab PRI, ntxiv rau kev hu xov tooj hauv Internet.
Cov haujlwm ntawm cov PBX digital yog raws li hauv qab no:
- Nws pib txais tos - tus neeg hu xov tooj suab sib tham, uas yuav pab txuas tus neeg hu nrog cov neeg sab hauv;
- lub suab xa ntawv - yog tias tus neeg sau npe tsis khoom, tus hu tuaj yeem tuaj yeem tawm suab lus;
- Kev sib txuas lus DECT - pub rau cov neeg ua haujlwm tsiv mus nyob ib puag ncig lub chaw haujlwm nrog tes ntaus DECT;
- IP telephony - cov kev sib txuas lus sib txuas lus uas xa cov suab lus nrov hla lwm IP tes haujlwm lossis hauv Is Taws Nem;
- CTI (Kev Sib Tham Hauv Computer Telephony) - tso cai rau koj los sib xyaw mini-ATS nrog software;
- hu xov tooj sib tham - muab kev sib txuas lus ntawm ntau tus neeg koom rau tib lub sijhawm;
- chaw taws teeb tswj hwm cov xov tooj digital mini-automatic sib hloov - tso cai rau koj los kho thiab txhim kho cov kev sib tham xov tooj tsis zoo ntawm qhov deb;
- cov lus ceeb toom sab nraud nrov nrov (paging), uas tso cai rau koj kom pom tus neeg ua haujlwm raug cai lossis ceeb toom rau txhua tus neeg ua haujlwm txog ib qho xwm txheej.
