I-DSL yindlela eyaziwa kakhulu yokubamba iqhaza kokuhlala Ezinsizeni ze-ternet. Isele enye yezintandokazi ze-intanethi ezithandwa kakhulu ekhaya iminyaka eminingi njengoba abahlinzeki beqhubeka nokuthuthukisa ingqalasizinda yabo yenethiwekhi ukwenyuka ukukhula ngesivinini. Abaningi balabo abahlinzeki abafanayo banikeza nezinsizakalo zeBhizinisi DSL kumakhasimende ezinkampani.
Okwenza iBusiness DSL ihluke
Iningi lamasevisi e-DSL asekhaya asebenzisa uhlobo lobuchwepheshe olubizwa nge-DSL asymmetric ( ADSL ). Nge-ADSL, iningi lomkhawulokudonsa wenethiwekhi otholakala kuxhumano lwe-intanethi lunikezwa ukulandwa nge-bandwidth engaphansi kakhulu etholakalayo yokulayisha. Isibonelo, uhlelo lomsebenzi we-ADSL lwasekhaya olulinganiselwe ama-3 Mbps lusekela ukuvinjelwa kwezingu-3 Mbps kodwa ngokuvamile ku-1 Mbps kuphela noma ngaphansi ukuhamba kokulayisha.
I-DSL ye-asymmetric yenza umqondo omuhle kumanethiwekhi okuhlala, ngoba amaphethini abasebenzisi abasebenzisa i-inthanethi evamile ahlanganisa ukulandwa njalo (ukubuka amavidiyo, upheqa iWebhu, futhi ufunde i-imeyli) kodwa ukulayishwa okuncane ngokuphindaphindiwe (ukuthumela amavidiyo, ukuthumela i-imeyili). Emabhizinisini, Nokho, leli phethini alisebenzisi. Amabhizinisi avame ukukhiqiza futhi adle inqwaba yedatha, futhi angakwazi ukulinda isikhathi eside ukudluliselwa kwedatha kunoma iyiphi indlela. I-ADSL akuyona isisombululo esihle kunazo zonke kule simo.
I-SDSL ne-HDSL
Igama elithi S DSL ( DSL symmetric) libhekisela kwamanye ubuchwepheshe be-DSL ukuthi, ngokungafani ne-ADSL inikeza umkhawulokudonsa ofanayo wokulayisha nokulandwa. Ethuthukiswe ekuqaleni eYurophu ngawo-1990, i-SDSL yaqala ukuqala emakethe ye-Internet eminyakeni eminingi edlule. Ubuchwepheshe be-DSL ngalezo zinsuku kudingeke ukuba kufakwe imigqa yezingcingo ukuze kuhlukaniswe ngokwehlukana ukuhamba kwemigwaqo ehamba phambili nangaphansi. I-SDSL ingenye yefomu zokuqala ze-DSL ukusebenza nomugqa owodwa wefoni. Ifomu lokuqala le-SDSL elibizayo elibizwa nge- HDSL (izinga eliphezulu le-DSL) lidinga imigqa emibili kodwa kamuva yenziwa ingasebenzi.
I-SDSL inayo yonke izici ezivamile ze-DSL, kufaka phakathi "njalo" ukuhlanganiswa kwezinsizakalo zezwi neyedatha, ukutholakala kunqunyelwe ibanga elingokwenyama, nokufinyelela okusheshayo okusheshayo kuqhathaniswa nemodemu ye-analog. I-Standard SDSL isekela amanani wedatha avela ku-1.5 Mbps ngezinga eliphakeme elihlinzekwa ngabanikezeli abathile.
Ingabe i-DSL yebhizinisi idumile?
Abahlinzeki abaningi be-intanethi emhlabeni wonke banikeza izinhlelo zesevisi ze-DSL, ngokuvamile ezilinganisweni eziningi zamanani nokusebenza. Ngaphandle kwamaphakheji e-SDSL, abanye abahlinzeki abakhulu (ikakhulukazi e-US) bayakwazi futhi ukunikeza amaphakheji e-ADSL aphezulu-khulu, futhi basebenzisa ingqalasizinda abakhele amakhasimende abo abahlala kuyo.
I-DSL yebhizinisi ihlala isetshenziselwa ezinye zezizathu ezifanayo njenge-DSL yokuhlala ye-intanethi:
- ukusetshenziswa kweminye imigqa yocingo kwenza i-DSL ibe lula ukufaka kunezinye izinhlobo zezinsizakalo ze-intanethi lapho kudingeke khona ukugijima kwekhebula elihlukile
- Izinketho ze-Inthanethi ezingenantambo azikafiki esiteji lapho zinikeza khona inhlanganisela efanele yezindleko, ukuthembeka nokusheshisa
