Amasevisi we-DSL Lookup kanye nezici ezithinta ukutholakala kwe-DSL
I-DSL (i-Digital Subscriber Line) isevisi ye-intanethi esheshayo ikhona ezindaweni eziningi kodwa hhayi kwezinye eziningi. Izici ezimbalwa zobuchwepheshe zinciphisa ukuhlinzekwa kwabanikezeli benkonzo ye-DSL njengoba kuchaziwe ngezansi.
Ihlola ukutholakala kwe-DSL
Ungahlola ukuthi ngabe i-DSL iyatholakala endaweni yakho ngokumane ifaka ikheli noma inamba yocingo ibe yinye yezinhlelo zokusebenza ze-DSL zokungena. C | Net, isibonelo, inikeza leli sayithi ukuhlola ukutholakala kwe-DSL kanye nezinye izinhlobo zezinsizakalo ze-intanethi:
- Ukufinyelela kwe-Inthanethi ku-cnet.com
Lezi zinsizakalo ze-intanethi zibika isimo senkonzo ye- intanethi endaweni yakho evamile futhi inembile isikhathi esiningi. Uma lookup ibonisa ukuthi isevisi ye-DSL ayitholakali endaweni yakini, kungenzeka ukuthi leyo nsizakalo isanda kusungulwa (kusho emavikini ambalwa edlule). Ngakolunye uhlangothi, noma ngabe i-lookup ibonisa ukuthi i-DSL ikhona endaweni yakini, usengabhekana nobunzima ekubhaliseni njengoba kuchaziwe ngezansi.
Ukulinganisa komugqa we-DSL
Ukuze ufanelekele isevisi ye-DSL, umugqa wakho wefoni kufanele ufaneleke umhlinzeki wesevisi . Lena inqubo umhlinzeki nabachwepheshe bazo abaqedile uma uqala ukubhalisela inkonzo. Imikhawulo embalwa yezobuchwepheshe ingavimbela ukuhlala kwakho ekufanelekeleni i-DSL:
Ukulinganiselwa Kwebanga - Ubuchwepheshe be-DSL bubucayi obude . Ngamafuphi, kusho ukuthi indawo yokuhlala kufanele ibe khona ngaphakathi kwebanga elithile (ngokwemvelo cishe ngo-18000 ft / 5 km) kude nenkampani yenkampani yendawo yendawo (ebizwa ngokuthi ihhovisi eliphakathi noma ukushintshaniswa komphakathi). Ezimweni ezingavamile, umakhelwane wakho ekhoneni angase afanelekele i-DSL kodwa awukwazi, ngenxa yalokhu kunqunywa kwebanga. Yingakho abantu abahlala ezindaweni zasemaphandleni abakwazi ukubhalisela isevisi ye-DSL.
Ikhwalithi yomugqa - Amanye imininingwane ephansi yezobuchwepheshe ngaphandle kwe-control yakho anquma ukuthi noma ngabe ucingo luni lwekhwalithi eyanele yegesi ukusekela i-DSL. Lezi zihlanganisa ukukhona kwamakhoyili wokulayisha . Ikhoyili yokulayisha iyisidingo encane kagesi esithuthukisa ikhono lomugqa wokudlulisela izwi lomuntu. Izinkampani zocingo zifake la madivaysi emigqeni phezu kweminyaka ukuthuthukisa ikhwalithi yenkonzo yabo. Kodwa ngokumangalisayo, ngenkathi izinsimbi zokulayisha zisebenza ngokuphumelelayo emazingeni aphansi (ngezwi), zithinta kakhulu amazinga aphezulu (idatha ye-DSL). Isevisi ye-DSL ayisebenzi kangcono ngamakhoyili wokulayisha.
Ukutholakala komkhawulokudonsa kwe-DSL
I- bandwidth yenethiwekhi ekugcineni uzokujabulela ne-DSL futhi ingathembela kumcingo wocingo lomhlinzeki wensizakalo. Njengoba isikhathi eside phakathi komuzi wakho kanye nesikhungo somhlinzeki wensizakalo, i-DSL engaphansi ye-bandwidth ingase isekele. Ngokufanayo, ukuqina kwalo (wire gauge) kungathinta ukusebenza. Umakhelwane wakho phansi kwebhulogi angase ahlangane ngokushesha (noma kancane) uxhumano lwe- DSL lwe- intanethi ngalesi sizathu.
I-bandwidth esiphezulu ye- Asymmetric Digital Subscriber Line (ADSL) etholakalayo ekulandeleni i-Inthanethi ngokusekelwe ubude bekhamera yefoni iboniswa ngezansi. Amanani wedatha anikezwa ngamunithi wama- kilobits ngomzuzwana (Kbps) :
- 8,448 Kbps ku-9,000 ft noma ngaphansi
- 6,312 Kbps kufika ku-12,000 ft.
- I-2,048 Kbps kufika ku-16,000 ft.
- I-1,544 Kbps kufika ku-18,000 ft.
Njengoba ubude bamakholi wefoni buyanda, ukutholakala kwe-bandwidth ye-DSL kunciphisa kokubili ukulayishwa nokulandwa. Isibonelo esiboniswe ngenhla sisekelwe ku-24-gauge wiring; ukusebenza kuyanciphisa uma i-26-gauge wire ikhona ku-loop.
