Main Mbali zaFoni Yadzidzidzi ya Tunnelndi Broadcasting

1. Kasamalidwe ka netiweki kachitidwe ndi kukonza kwakutali

Chifukwa chogwiritsa ntchito ma intaneti a IP, kasamalidwe ka maukonde ndi kukonza kwakutali kwa zida zitha kuchitidwa mwaukadaulo kulikonse padziko lapansi, zomwe zimathandizira kwambiri kuthetsa mavuto ndi kukonza. Adilesi ya IP, nambala yafoni, FSK kapena DTMF mtundu wa zida zitha kukhazikitsidwa patali kudzera mu IE, ndi magawo apakati monga manambala a foni.

2. Kuphatikiza ndinjira yowulutsira mumphangayo, kulamulira ndi kasamalidwe kogwirizana

Foni yamsewu yadzidzidzi ndi njira yolumikizira njira yowulutsira imatha kutulutsa siginecha yowongolera kuwulutsa, ndipo amplifier yamagetsi yakunja imatha kuyendetsa mwachindunji cholankhulira cholozera mwamphamvu. Panthawiyi, kufalikira kwa telefoni yadzidzidzi ndi njira yowulutsira njirayo imatha kugwira ntchito nthawi imodzi, ndipo malo ang'onoang'ono amatha kufalitsa "pulogalamu yoyendetsedwa" ndikuzindikiritsa kuwulutsa kwa njirayo.

3. Matelefoni ndi wailesi yamwadzidzidzi amatha kugwiritsa ntchito njira zonse ziwiri popanda manja komanso kuyimba mafoni nthawi imodzi, oyenera anthu amitundu yonse.

Njira yoyitanitsa opanda manja yaIP foni yachanguimangofunika kugwiritsa ntchito batani limodzi, ndipo kuyimbako kumatha kuchitika. Phokosoli ndi lowala komanso lomveka bwino. Kuthamanga kwa phokoso pa 40 cm kutsogolo kwa wokamba nkhani kumafika 90DB. MIC ili ndi chidwi kwambiri ndipo ndiyosavuta kuyimba mafoni opanda manja. Makina ogwiritsira ntchito amangolumikizana ndi foni, yomwe ndi yosavuta kugwiritsa ntchito popanda kuyimba, ndipo imatha kugwiritsidwa ntchito ndi okalamba ndi ana.

4. Foni yadzidzidzi ndi wailesi yomwe ili mumsewu ili ndi magetsi osungira, omwe amatha kugwiritsidwabe ntchito nthawi zonse mphamvu ikatha.

Monga njira yolumikizirana mwadzidzidzi, mphamvu yosunga zobwezeretsera ndiyofunikira. Foni yachangu ya IP ili ndi magetsi osungira. Pakakhala magetsi a 220V AC, chipangizocho chimagwiritsa ntchito magetsi a AC ndikulipiritsa batire. Mphamvu yamagetsi ya 220V AC ikatha, chipangizocho chimangosinthiratu kupita kugawo la batire. Zipangizozi zitha kugwiritsidwabe ntchito moyenera. Zindikirani: Mphamvu ya batri ndi yochepa. Chonde bwezeretsani magetsi a AC munthawi yake mphamvu ikatha.

5. Ziwerengero zanzeru ndi funso

Ogwira ntchito amatha kufunsa mafunso osiyanasiyana okhudza ngozi zapamsewu ndi kulephera kwa zida pakompyuta yoyang'anira ntchito, ndipo amatha kufunsa mafunso owerengera malinga ndi zinthu zambiri monga nthawi, malo, mtundu wa ngozi, mtundu wagalimoto, kapena mtundu wakulephera kwa zida. Zotsatira zamafunso zimayikidwa m'magulu osiyanasiyana a Zithunzi ndi kusindikiza. Mwa kufunsa za zida zoulutsira matelefoni zadzidzidzi, ntchito yonse ya dongosololi imatha kuzindikirika nthawi iliyonse, ndipo mkhalidwe wamisewu ungamvetsetsedwe munthawi yake pofunsa za ngozi zapamsewu.

6. Pogwiritsa ntchito njira yotumizira IP, kumangako ndi kosavuta komanso kosavuta kukulitsa ndi kusamalira. Matelefoni adzidzidzi achikhalidwe amagwiritsa ntchito chingwe, kuwala kwa fiber ndi njira zina zotumizira, zomwe zimafunika kuyala zingwe zapadera zoyankhulirana. Kumanga ndi kugwirizanitsa ndizovuta ndipo kulankhulana kudzayimitsidwa ngati chingwe chathyoledwa. , Dongosolo lowulutsa mafoni adzidzidzi la IP limatenga maukonde a IP, omwe ndi osinthika komanso odalirika. Kumene kuli IP, mukhoza kuwonjezera momwe mukufunira, ndipo paketi ya IP ili ndi ntchito yolowera. Ngati njira imodzi yatsekedwa kapena kusokonezedwa, mayendedwe ena amatha kusankhidwa kuti apitilize kufalitsa, ndipo kutumizirako ndikodalirika. Kudalirika kwakukulu, komanso ukadaulo wapadziko lonse lapansi wa IP network uli ndi ntchito yamphamvu yowunikira maukonde, ndikuwongolera zovuta zakutali kumatha kuchitika mosavuta komanso mwachangu mukatha kulumikizana ndi kulephera kwa zida.

Ningbo Joiwo Kuphulika-umboni, mwapadera kupanga matelefoni osaphulika/osalowa madzi, matelefoni akundende ndi matelefoni a anthu osaonongeka kwa zaka zopitilira 17.

Timapanga mbali zambiri tokha (chimanja, keypad, hanger etc) .Tili ndi mitundu yonse ya makina opangira jekeseni, jekeseni, kufa kuponyera, hardware machining.Mafoni athu amagwiritsidwa ntchito kwambiri powononga mafuta, mafakitale a mankhwala, ndende, ngalande ndi zina zotero. .Monga wogulitsa wodalirika, titha kukupatsirani zinthu zamtengo wapatali komanso ntchito yabwino pambuyo pogulitsa.
