DSL teknolojisini kullanabilmeniz i\u00e7in konumunuzun, size servis sa\u011flayan telefon santraline en fazla 3 mil uzakl\u0131kta olmas\u0131 gerekmektedir. DSL hizmetini almak i\u00e7in bulundu\u011funuz b\u00f6lgedeki DSL servis sunucusunu arayarak bilgi alabilirsiniz.<\/p>\n\n\n\n

DSL T\u00fcrleri<\/strong><\/p>\n\n\n\n

DSL t\u00fcrleri kullan\u0131lan tel uzunlu\u011fu, bant geni\u015fli\u011fi, sinyal iletim \u015fekli ve h\u0131z\u0131 gibi \u00f6zelliklere g\u00f6re farkl\u0131l\u0131k g\u00f6stermektedir. DSL, ADSL de d\u00e2hil olmak \u00fczere t\u00fcm DSL teknolojisini kapsar. En yayg\u0131n olarak kullan\u0131lan DSL ailesi \u00fcyeleri, HDSL ve ADSL’dir.<\/p>\n\n\n\n

ADSL (Asymmetric Digital Subscriber Line)<\/strong><\/p>\n\n\n\n

ADSL asimetrik DSL anlam\u0131nda olup, veri al\u0131m ve g\u00f6nderim h\u0131zlar\u0131n\u0131n birbirinden farkl\u0131 olabilmesini ifade eder. Veri al\u0131m h\u0131z\u0131, veri g\u00f6nderim h\u0131z\u0131ndan fazlad\u0131r. G\u00fcn\u00fcm\u00fczde en \u00e7ok kullan\u0131lan ba\u011flant\u0131 teknolojisidir. Telefonlar i\u00e7in kullan\u0131lan bak\u0131r teller \u00fczerinden veri, ses ve g\u00f6r\u00fcnt\u00fc ileti\u015fimini ayn\u0131 anda sa\u011flayabilmektedir. ADSL teknolojisin \u00f6zellikleri temel al\u0131narak ADSL2 ve ADSL2+ teknolojileri geli\u015ftirilmi\u015ftir.<\/p>\n\n\n\n

VDSL (Very-High Bitrate Digital Subscriber Line)<\/strong><\/p>\n\n\n\n

VDSL,  y\u00fcksek h\u0131zl\u0131 abone hatt\u0131 anlam\u0131na gelmektedir. Santrale k\u0131sa mesafede bulunan internet kullan\u0131c\u0131lar\u0131 i\u00e7in y\u00fcksek bant geni\u015fli\u011fi sunar. H\u0131zl\u0131d\u0131r ve iletimi bak\u0131r kablo vas\u0131tas\u0131yla ger\u00e7ekle\u015ftirir. ADSL hizmeti de bak\u0131r kablo kullanmaktad\u0131r fakat VDSL hizmetinin kullan\u0131c\u0131ya y\u00fcksek bant geni\u015fli\u011fi sunmas\u0131yla ADSL hizmetinden farkl\u0131la\u015f\u0131r. Devam\u0131nda VDSL2 teknolojisi geli\u015ftirilmi\u015ftir.<\/p>\n\n\n\n

SDSL (Symmetric Digital Subscriber Line)<\/strong><\/p>\n\n\n\n

SDSL simetrik DSL anlam\u0131nda olup sinyalleri simetrik olarak iletir. ADSL hizmetinin aksine veri al\u0131m ve g\u00f6nderim h\u0131zlar\u0131 i\u00e7in ayn\u0131 kapasiteyi sunar. 2 Mb\/s h\u0131z\u0131ndaki verileri bak\u0131r kablo arac\u0131l\u0131\u011f\u0131yla \u00e7ift y\u00f6nl\u00fc olarak ta\u015f\u0131r. <\/p>\n\n\n\n

HDSL(High Bit Rate Digital Subscriber Line)<\/strong><\/p>\n\n\n\n

HDSL y\u00fcksek bit h\u0131z\u0131nda say\u0131sal abone hatt\u0131 anlam\u0131na gelmektedir. Bak\u0131rdan simetrik kablo \u00e7iftleri kullan\u0131r. Y\u00fcksek frekansta bant geni\u015fli\u011fine izin veren ilk DSL teknolojisidir. Yeni kurulumlarda fiber kablo kullan\u0131lmaktad\u0131r. HDSL d\u00fc\u015f\u00fck maliyet, y\u00fcksek performans ve d\u00fc\u015f\u00fck bak\u0131m vb. \u00f6zelliklerinden dolay\u0131 hala tercih edilmektedir. HDSL2 ve SDSL teknolojileri HDSL hizmetinin \u00f6zelliklerini kullanarak geli\u015fmi\u015ftir.<\/p>\n","protected":false},"excerpt":{"rendered":"
