I-DSL yifomu eyaziwayo yoluntu olubanzi lweendawo zokuhlala Kwiinkonzo ze-ternet. Liye lahlala linye lezona zikhethwa kakhulu kwiindawo ze-Intanethi kwiindawo ezininzi njengabantu ababonelela ngeenkonzo eziqhubekayo ukuphucula izibonelelo zabo zenethiwekhi ukwenzela ukwandisa isantya. Uninzi lwaba banikezeli abafanayo banikezela ngeenkonzo ze- Business DSL kumakhasimende abambiswano.
Kutheni i-DSL yeBusiness ihlukile
Uninzi lweenkonzo ze-DSL zasekhaya zisebenzisa uhlobo lwetheknoloji ebizwa ngokuba yi-DSL ye-asymmetric ( ADSL ). Nge-ADSL, uninzi lwe- bandwidth yenethiwekhi efumaneka kwi-intanethi ye-Intanethi inikezelwa ukulandwa kunye ne-bandwidth engaphantsi kwee-uploads. Ngokomzekelo, icebo leenkonzo ze-ADSL ekhaya lilinganiswe kwi-3 Mbps lixhasa ukukhawuleza ukukhawuleza ukuya kwi-3 Mbps kodwa ngokuqhelekileyo kuphela i-1 Mbps kuphela okanye ngaphantsi kwezabelo zokulayisha.
I-DSL ye-Asymmetric yenza ingqiqo yeenethiwekhi zokuhlala, kuba iimeko eziqhelekileyo zokusetyenziswa kwe-intanethi zabathengi zibandakanya ukukhuphela rhoqo (ukujonga iividiyo, ukukhangela iWebhu, nokufunda i-imeyile) kodwa ngokukhawuleza ukulayisha (ukuthumela iividiyo, ukuthumela i-imeyile). Kwimashishini, nangona kunjalo, le pateni ayisebenzisi. Amashishini athile avelise kwaye adle ixabiso elikhulu leedatha, kwaye abanako ukukwazi ukulinda ixesha elide ukudluliselwa kwedatha kuyo nayiphi na indlela. I-ADSL ayiyona isisombululo esona sihle kule meko.
SDSL kunye ne-HDSL
I- S DSL (i-DSL ye-symmetric) ibhekisela kwezobuchwepheshe obuthile be-DSL, ngokungafani ne-ADSL inikezela umda wokulinganisa olinganayo ukulayisha kunye nokulandwa. Ekuqaleni kwaveliswa eYurophu kwiminyaka ye-1990, i-SDSL yafumana ukuqala kwintengiso kwi-Intanethi kwiminyaka emininzi edlulileyo. Ubuchwepheshe be-DSL ngaloo mihla ngokuqhelekileyo kufuneka ukuba ufake iifowuni zeefowuni ukulawula ngokwahlukileyo ukulawula i-traffic and downstream traffic. I-SDSL yenye yeendlela zokuqala ze-DSL ukusebenza nomgca omnye wefowuni. Ifom ye-SDSL ephakamileyo ye-SDSL ebizwa ngokuba yi- HDSL (izinga eliphezulu le-DSL) lifuna imigca emibini kodwa kamva yenziwe ingasebenzi.
I-SDSL inezo zonke iimpawu eziqhelekileyo ze-DSL, kubandakanywa "rhoqo" kwiinkonzo zeenkonzo zezwi kunye neenkcukacha, ukufumaneka okunqunywe ngumgama ongokwenyama, kunye nokufikelela okukhawulezayo ngokuthelekiswa nemodemu ye-analog. I-SDSL ye-Standard isekela amaxabiso eedatha aqala kwi-1.5 Mbps enezantya eziphezulu ezibonelelwa ngabanikezeli abathile.
I-DSL yeShishini ibonakala kakhulu?
Ababoneleli abaninzi be-intanethi kwihlabathi jikelele banikezela izicwangciso zeenkonzo ze-DSL, ngokuphindaphindiweyo kumaxabiso amaninzi kunye nentsebenzo. Ukongeza kwiiphakheji ze-SDSL, abanye ababonelela ngeenkonzo ezinkulu (ikakhulukazi e-US) banako ukunikela ngeephakheji ze-ADSL eziphakamileyo eziphezulu, kunye nokusebenzisa izibonelelo zabo abakhele amakhasimende abo abahlala kuzo.
I-DSL yezo shishino isaziwayo kwezinye iinjongo ezifana ne-DSL Internet:
- Ukusetyenziswa kwemigangatho yefowuni eqhelekileyo kwenza i-DSL ifake ukulula kunezinye iindlela zeenkonzo ze-intanethi apho kufuneka ukuba i-cable ehlukeneyo iqhube
- Izinketho ze-intanethi ezingenakucingo ezingakayi kuqhutyelwa kwinqanaba apho zinikezela ngokudibeneyo kweendleko, ukuthembeka nokukhawuleza
