I-Digital Subscriber Line (DSL) yisevisi ye-intanethi ephezulu kwiimakhaya nakwiimashishini ezikhuphisana nekhefu kunye nezinye iindlela ze- intanethi ye-intanethi . I-DSL inikeza inxibelelwano ngokukhawuleza kwinqanaba kwiifowuni eziqhelekileyo usebenzisa i- modem ye-broadband . I-teknoloji emva kwe-DSL yenza i-intanethi kunye nenkonzo yocingo isebenze ngaphaya komgca wefowuni ngaphandle kokufuna ukuba abathengi banqamle i-voice yabo okanye i-Intanethi.
I-DSL Speed
I-DSL yeSiseko isekela iqondo lokukhuphela kwedatha ephezulu phakathi kwe-1.544 Mbps kunye ne-8.448 Mbps. Ukwenyuka okwenziweyo kuyahlukahluka ngokubhekiselele kumgangatho wefowuni yefowuni yokufakelwa komgca. Ubude bomgca wefowuni olufunekayo ukufikelela kwisixhobo sokubonelela ngeenkonzo (ngezinye izihlandlo esibizwa ngokuthi "i-ofisi ephakathi") sinokunciphisa isantya esiphezulu sokufakwa kwe-DSL.

I-DSM ye-Symmetric
Uninzi lweentlobo zeenkonzo ze-DSL zi-asymmetric-ezaziwa nangokuthi yi- ADSL . I-ADSL inikela ngesivinini esiphezulu sokukhuphela kunokuba ulayishe ngesivinini, i-tradeoff abanikezeli benkonzo abaninzi abenza ukulungelelanisa ngakumbi neemfuno zamakhaya aqhelekileyo abenza ngokubanzi ukukhuphela. I-DSL yeSimmetric igcina ixabiso leedata elilinganayo kokulayisha kunye nokulandwa.
INkonzo yeDSL
Abanikezeli be-DSL abaziwayo e-United States baquka i-AT & T (i-Uverse), iVerizon kunye ne-Frontier Communications. Abanikezeli bencinci baninzi banika iDSL. Abathengi babhalisela kwisicwangciso senkonzo ye-DSL kwaye bahlawula ukubhaliswa kwenyanga okanye ngonyaka kwaye kufuneka bavumelane nemimiselo yesevisi. Uninzi lwababoneleli banikezela ngeemodareyitha ze-DSL ezihambelana nabaxumi babo xa zifuneka, nangona i-hardware ifumaneka ngokubanzi ngabadayisi.
INkonzo yeDSL
Ngaphandle kokuthandwa kwawo emakhaya, amashishini amaninzi athembela kwi-DSL ngeenkonzo zabo ze-intanethi. I-DSL yezoShishino ihluke kwiDSL yokuhlala kwiindawo ezimbalwa eziphambili:
- I-DSM ye-Symmetric isetyenziswa ngokuqhelekileyo njengamashishini atya ukuvelisa umthamo ophezulu kakhulu weendlela eziphumayo kunekhaya eliqhelekileyo
- Ababoneleli bavame ukuthengisa amanqanaba aphezulu enkonzo kubathengi babo kubandakanywa izicwangciso zezinga eliphezulu zamanani, iinketho zokuxhaswa kwabathengi bokuqala okanye ukuthengwa kweminye imikhiqizo

Iingxaki ngeDSL
Inkonzo ye-Intanethi ye-DSL isebenza kuphela kumgama olinganiselwe umzimba kwaye ayihlala ikhona kwiindawo ezininzi apho iziseko zengingqi zendawo zingenayo inkxaso kwi-DSL.
Nangona i-DSL ibe yintlobo yeenkonzo ze-intanethi kwiminyaka emininzi, amava ngamnye kumntu athengisa kakhulu ngokuxhomekeka kwindawo yabo, umnikezeli wabo, umgangatho wiringaniso yefowuni kwindawo yokuhlala kunye nezinye izinto.
Njengaye nezinye iintlobo zeenkonzo ze-intanethi, indleko ye-DSL ingahluka ngokubanzi ukusuka kummandla ukuya kummandla. Indawo eneenkcukacha ezimbalwa zokuxhuma kwi-intanethi kunye nabanikezeli abancinci banokubangela ukwanda kwexabiso ngenxa nje yokungabikho komncintiswano shishino.
I-DSL ayenzi ngokukhawuleza nje ngokukhawuleza njenge- fiber Internet . Nangona ezinye iinketho ze-Intanethi ezingenasiphelo ezingenantambo zinganceda ukukhawuleza.
Ngenxa yokuba imigca ye-DSL isebenzisa ucingo olufanayo lobhedu njengesevisi yocingo yefowuni, zonke iifowuni ezifowunwe ekhaya okanye ishishini kufuneka zisebenzise izihlomelo ezikhethekileyo ezifake phakathi kwefowuni kunye nodonga lwodonga. Ukuba ezi zifowuni zingasetyenziswanga, uxhulumaniso lwe-DSL lunokuchaphazeleka.
