Kodi tsatanetsatane wa matelefoni a mafakitale ndi chiyani?

Tikafuna kuyimba foni, tenga chogwirizira cha foni ndikusiya chingwe cholumikizira chikukonzekera kulumikizidwa, ndipo tikayimitsa foni, ikani chogwirira chake ndipo chingwecho chidzadutsidwa. Kuitana kukalowa, belu limalira ndipo mzerewo wakonzeka kulumikizidwa.

Infoni yamakampani,zigawo zomwe zimazindikira izi ndi izi: cholumikizira cha m'manja, cholumikizira cholumikizira, choyimba (kapena makiyi), mphete yafoni ndi loop yafoni.

Maikolofoni ndi kabokosi kakang'ono kamene kali ndi tinthu ta carbon. Kabokosi kakang'ono kamakhala ndi electrode yokhazikika kumbuyo ndi nembanemba yogwedezeka (yotchedwa electrode yogwedeza) kutsogolo. Mukalankhula mu maikolofoni, nembanemba yogwedezeka imagwedezeka mosiyanasiyana ndi kusintha kwa mawu, kotero kuti ma carbon particles nthawi zina amaponderezedwa (kukana kumachepetsa), ndiyeno kumasuka (kukaniza kumawonjezeka), kotero kuti kutuluka kwa awiriwo. panopa pakati pa maelekitirodi amasinthanso. Mwa njira iyi, kusintha kwa kukula kwa phokoso kumasinthidwa kukhala kusintha kwa mphamvu ya chizindikiro chamagetsi choyenera kufalitsa pa dera.

Thupi la wolandila ndi maginito okhazikika okhala ndi bala lozungulira mozungulira. Liwu lochokera ku mbali ina likadutsa pa koyiloyo, mphamvu ya maginito imapangidwa, yomwe imakopa chitsulo chopyapyala chomwe chili kutsogolo kwa maginito kuti chigwedezeke ndi kutulutsa mawu. Kukula kwa kugwedezeka kumatsimikiziridwa ndi kukula kwa panopa kumayenda kupyolera mu koyilo. Ichi ndi chifukwa chophweka chomwe wolandirayo amatha kubwezeretsa chizindikiro chamagetsi kuti chimveke.

Tikakhala pa foni, chochita choyamba ndi "kuchotsa mbedza" (kuchotsa foni pafoni). Panthawiyi, gawo la foni yomwe imanyamula foni (yotchedwa "hook") ikukwera, kutseka dera pakati pa telefoni ndi kusintha. Ngati chingwe chosinthira chili chaulere panthawiyi, chimatumiza "dial tone" mosalekeza ku telefoni, yomwe imakuuzani kuti: "Ndili kale pa standby, chonde imbani!"

Mafoni a foni ndi ozungulira komanso mabatani. kutumizidwa poyimba nawo.Ndi DC pulse kapena siginecha yapawiri. Ziribe kanthu mtundu wa chizindikiro, udindo wawo ndi kulamulira.Yang'anirani chosinthira muofesi yamafoni kuti chilole kuti chimalizitse kulumikizana pakati pa woyimbayo ndi woyimbayo.

Ngati foni yoyimbidwayo ilibe ntchito, chosinthiracho chimatumiza kulira kwa iyo, kupanga foni ya gulu lina

Foni inaitana. Uku akuuza gulu lina kuti: "Wina akuitana!" Nthawi yomweyo, woyimba

Wogwiritsa amva "Ringback Tone". Ngati foni ya winayo palibe, chosinthiracho chidzapatsa woyimbirayo.Wogwiritsa amatumiza "mawu otanganidwa" a "beep, beep, beep ...".

IP (Internet Protocol) fonindi telefoni ya digito, kulumikizana

ntchito yamakalata. Imaphatikiza mawu, kuponderezana ma code, kuyika, mayendedwe, kusungirako ndi kusinthanitsa

Imatha kuzindikira kulankhulana kwamawu pa netiweki ya IP kapena intaneti kudzera mukusinthana monga kusinthana, kutsitsa, ndi decompression. zimalimbikitsa

Imawongolera kagwiritsidwe ntchito kazinthu zama network ndikuchepetsa mtengo wa mautumiki a mawu. Choncho, zakhala mofulumira

Titha kunena kuti ndi ntchito yomwe ikukula mwachangu komanso yotchuka kwambiri padziko lonse lapansi masiku ano.

Ndi imodzi mwaukadaulo wautumiki komanso imodzi mwamalo omwe amapezeka kwambiri pamakampani apakompyuta.

Masiku ano,mafoni amtundu wa analogi ndi IPamagwiritsidwa ntchito kwambiri polankhulana m'mafakitale.Ningbo Joiwo ndi katswiri wopanga matelefoni osaphulika/osalowa madzi, matelefoni akundende ndi matelefoni a anthu onse osaonongeka kwa zaka zoposa 17.

Timapanga zigawo zambiri mwa ife tokha (m'manja, keypad, hanger etc).Ngati mukufuna, chonde omasuka kulumikizanani ndi izi:
