Cable modems ikugwirizanitsa makompyuta a nyumba kumalo osungirako chingwe cha Internet service provider . Ma modem awa amalowa mu msewu waukulu pamtunda umodzi, makamaka pogwiritsa ntchito chingwe cha USB kapena chingwe cha Ethernet , ndi chipinda cha khoma (kutsogolera ku chakudya cha chingwe) kumapeto ena.
Nthaŵi zina, ogula ayenera kugula modemswa mwachindunji , koma nthawi zina sayenera, monga momwe tafotokozera m'munsiyi.
DOCSIS ndi Cable Modems
Dongosolo la Dongosolo la Dongosolo la Dongosolo la Dongosolo la Dongosolo la Dongosolo la Dongosolo (DOCSIS) limathandizira mawonekedwe a modem. Zonse zamakina opangira mauthenga pa intaneti zimafuna kugwiritsa ntchito modem compatible DOCSIS.
Mabaibulo atatu aakulu a DOCSIS modems alipo.
- Mabaibulo a DOCSIS 1.0 ndi 1.1 onsewa anapezeka kumapeto kwa zaka za m'ma 1990. Zimatha tsopano m'madera ambiri padziko lapansi. Ma modem awa amathandiza mpaka 38 Mbps kuti akhululuke ndi zolemba 9 Mbps.
- DOCSIS 2.0 imathandizira maulendo 38 ofikira mofulumira monga 1.x koma imapangitsa kuti mawindo apamwamba ajambule kuwunikira 27 Mbps. Zatsopano za D2.x modems zingathandizenso IPv6 (fufuzani zolemba zanu kuti zitsimikizire).
- DOCSIS 3 - mavesi 3.0 ndi 3.1 onse akuthandizira IPv6 kuphatikizapo mauthenga apamwamba kwambiri a bandwidth kuposa D1.x / D2.x, opitirira 100 Mbps. Iwo amatsatiranso kumbuyo ndi mawonekedwe akale a DOCSIS ndi ma intaneti.
Kawirikawiri mudzafuna kupeza modem D3 pa Intaneti. Ngakhale mitengo ya D3 modems yatsopano ingakhale yapamwamba kusiyana ndi machitidwe akale, kusiyana kwa mtengo kuli kuchepa kwambiri muzaka zochepa zapitazo. Zida za D3 ziyenera kupereka nthawi yochuluka zedi zamoyo kusiyana ndi machitidwe akale, ndipo (malingana ndi kukhazikitsidwa kwa makina)
Zindikirani kuti ome amene amagwiritsa ntchito intaneti akhala akugulitsa makasitomala awo apamwamba pamwezi pamwezi kuti agwiritse ntchito modem ya D3 pa intaneti yawo poyerekeza ndi machitidwe akale (chifukwa cha kuchuluka kwa magalimoto omwe D3 modems angapange). Fufuzani ndi wothandizira anu kuti mudziwe ngati izi ndizofunikira pakugula kwanu.
Pamene Sitiyenera Kugula Cable Modem
Musagule modem yachingwe pa zifukwa zitatu izi:
- Mapulogalamu anu a pa intaneti amafuna kuti makasitomala azigwiritsa ntchito modem zomwe zimaperekedwa ndi wopereka
- Phukusi lanu la intaneti likufuna kugwiritsa ntchito chipangizo chopanda chipata chopanda waya (onani m'munsimu) mmalo mwa modem
- mwina mumasamukira kumalo ena mofulumira ndipo mungathe kusunga ndalama zogwiritsa ntchito modem (onani m'munsimu)
Kugwiritsa Ntchito Cable Modems
Pokhapokha ngati mukukonzekera kusamukira kumalo osiyana mkati mwa chaka chimodzi kapena chimodzi, kugula modem yachingwe imapulumutsa ndalama pomaliza kubwereka. Pofuna kupereka chipangizo chomwe akugwirizanitsa kuti chikhale chogwirizana, ogulitsa pa intaneti nthawi zambiri amapereka ndalama zosachepera $ 5 USD pa mwezi kuti apereke modems oyang'anira. Chipangizochi chingakhalenso chipangizo chogwiritsidwa ntchito kale, ndipo ngati chikulephera kwathunthu (kapena makamaka chimayamba kuchita zosavuta), wothandizira akhoza kukhala wochepetsetsa kuti asinthe.
Kuti muwonetsetse kuti mumagula modem ya broadband yovomerezeka ndi intaneti yanu, yang'anani ndi abwenzi kapena achibale omwe amagwiritsira ntchito modzipereka. Masitolo othandizirapo malonda ndi zothandizira pazithunzithunzi amakhalanso ndi mndandanda wa ma modem ovomerezeka ndi otsogolera akuluakulu. Gulani chinthucho kuchokera ku gwero lomwe limavomereza kubwerera, kotero kuti mutha kuyesa ndikusinthanitsa ngati kuli kofunikira.
Zitsembo Zopanda Zingwe Zokwera pa Intaneti
Ena opereka mauthenga a broadband amapereka makasitomala awo chipangizo chomwe chimaphatikiza ntchito za modem ya waya opanda waya ndi ya broadband mu chipangizo chimodzi. Zitseko zopanda zingwe zomwe zimagwiritsidwa ntchito pa Intaneti zamakina zakhazikitsa mu modem DOCSIS. Kulembera ku intaneti, ma TV ndi ma telefoni nthawi zina zimafuna kugwiritsa ntchito zipangizozi mmalo mwa modem yokha. Yang'anani ndi wothandizira wanu ngati sakudziwa zomwe akufuna.
