ISDN Teknolojisi Nedir?<\/h2>\n

ISDN (Integrated Services Digital Network), temel olarak mevcutta var alan analog telefon \u015febekesinin bir alternatifi. Bir ileti\u015fim standard\u0131 veya protokol\u00fc olarak ifade edebilece\u011fimiz ISDN, say\u0131sal ve analog hatlara ula\u015f\u0131m imkan\u0131 sunar. Fakat say\u0131sal bir ses kanal\u0131 ile birlikte veri (data) ileti\u015fimine de olanak sa\u011flamas\u0131, ISDN\u2019yi analog hatlardan farkl\u0131 k\u0131lar. Ses, veri ve g\u00f6r\u00fcnt\u00fc gibi farkl\u0131 bilgilerin say\u0131sal bir ortamda birle\u015ftirilerek ayn\u0131 hat \u00fczerinden iletilmesinin sa\u011flayan ISDN, g\u00fcvenli ve kaliteli bir ileti\u015fim a\u011f\u0131d\u0131r.<\/span><\/p>\n

ISDN Nas\u0131l \u00c7al\u0131\u015f\u0131r? \u00c7e\u015fitleri Nelerdir?<\/h2>\n

Ses, veri (data) ve g\u00f6r\u00fcnt\u00fc iletilmesine imkan sunan ISDN, say\u0131sal bir ileti\u015fim a\u011f\u0131 standard\u0131d\u0131r.\u00a0 ISDN\u2019ler kullan\u0131larak kullan\u0131c\u0131lar \u00e7evrimli say\u0131sal ba\u011flant\u0131 kurabilir. ISDN numaras\u0131na sahip ba\u015fka bir kullan\u0131c\u0131 ile\u00a0 \u00f6nce \u00e7a\u011fr\u0131 yap\u0131larak ba\u011flant\u0131 kurulur ve ileti\u015fim sa\u011fland\u0131ktan sonra ba\u011flant\u0131 sona erer. PRI ve BRI olmak \u00fczere iki ISDN \u00e7e\u015fidi ve hizmeti bulunmaktad\u0131r.<\/span><\/p>\n

BRI (Basic Rate Interface): <\/b>K\u00fc\u00e7\u00fck i\u015fletmeler, b\u00f6lgeler ve ev kullan\u0131c\u0131lar\u0131 i\u00e7in uygun olan BRI, daha k\u00fc\u00e7\u00fck bant geni\u015fli\u011fine sahiptir.<\/span> BRI, 2 tane 64 Kbps\u2019lik veri (data) kanal\u0131 ve 1 adet 16 Kbps\u2019lik D ad\u0131nda kanal bulunur. D kanal\u0131 kontrol ve senkronizasyon ama\u00e7la kullan\u0131l\u0131r.<\/span><\/p>\n

PRI (Primary Rate Interface): <\/b>Y\u00fcksek bant geni\u015fli\u011fi sa\u011flayan PRI, b\u00fcy\u00fck i\u015fletmeler veya \u015firketler taraf\u0131ndan tercih edilir. 2 Mbps band geni\u015fli\u011fine sunan PRI, Avrupa standard\u0131nda (E1 PRI) 30 adet 64 Kbps\u2019lik kanal mevcuttur. Ayr\u0131ca her bir kanal ba\u011f\u0131ms\u0131z olarak kullan\u0131labilir.<\/span><\/p>\n

ISDN\u2019in Avantajlar\u0131 Nelerdir?<\/h2>\n
    \n
  • Hem ev hem de i\u015f yerlerinde kullan\u0131labilir.<\/span><\/li>\n
  • Ses, veri ve g\u00f6r\u00fcnt\u00fcy\u00fc e\u015f zamanl\u0131 olarak \u00e7al\u0131\u015ft\u0131rabilir.<\/span><\/li>\n
  • G\u00fcvenli ve h\u0131zl\u0131d\u0131r.\u00a0<\/span><\/li>\n
  • Bir\u00e7ok farkl\u0131 cihaz ayn\u0131 hat \u00fczerinden kullan\u0131labilir.<\/span><\/li>\n<\/ul>\n

    ISDN Kanallar\u0131 Nelerdir?<\/h2>\n

    Kullan\u0131m amac\u0131 ve bant geni\u015fli\u011fine g\u00f6re ISDN\u2019de 3 farkl\u0131 ileti\u015fim kanal\u0131 bulunur.\u00a0<\/span><\/p>\n

    B Kanal\u0131: <\/b>Veri, ses ve g\u00f6r\u00fcnt\u00fc gibi kullan\u0131c\u0131 verilerinin aktar\u0131lmas\u0131 i\u00e7in kullan\u0131lan kanald\u0131r. Tam ve \u00e7ift y\u00f6nl\u00fc mod i\u00e7inde senkron olarak 64 Kbps band geni\u015fli\u011finde bulunur.<\/span><\/p>\n

    D Kanal\u0131: <\/b>\u0130leti\u015fimin do\u011fru bir \u015fekilde ger\u00e7ekle\u015fmesi i\u00e7in gerekli olan i\u015faretleme ve senkronizasyonun yap\u0131lmas\u0131 i\u00e7in kullan\u0131l\u0131r. Ba\u011flant\u0131 i\u00e7in \u00e7a\u011fr\u0131 g\u00f6nderilir ve kar\u015f\u0131daki ki\u015fi taraf\u0131ndan bu \u00e7a\u011fr\u0131 kabul edilirse, aktar\u0131m i\u00e7in gerekli oturum haz\u0131rlan\u0131r ve t\u00fcm haberle\u015fmeler D kanal\u0131 \u00fczerinden ger\u00e7ekle\u015fir. Tam ve \u00e7ift y\u00f6nl\u00fc mod i\u00e7inde 16 Kbps ya da 64 Kbps bant geni\u015fli\u011finde bulunur.<\/span><\/p>\n

    H Kanal\u0131: <\/b>H1\u2019den H4\u2019e kadar 4 farkl\u0131 \u00e7e\u015fitte H kanal\u0131 yer al\u0131r. Tam \u00e7ift y\u00f6nl\u00fc olarak \u00e7al\u0131\u015fan H kanal\u0131, B kanal\u0131ndan daha y\u00fcksek band geni\u015fli\u011fine sahiptir. B kanal\u0131 gibi verilerin aktar\u0131lmas\u0131 i\u00e7in kullan\u0131l\u0131r.<\/span><\/p>\n

    ISDN teknolojisi her ge\u00e7en g\u00fcn daha fazla kullan\u0131l\u0131yor.
