SS7 ger\u00e7ekten de sadece kapal\u0131 bir sinyalizasyon sistemidir. Bir Telekom\u00fcnikasyon A\u011f\u0131ndaki d\u00fc\u011f\u00fcmler (\u00f6rne\u011fin Mahalle De\u011fi\u015fimi, MSC \/ VLR, GMSC, vb.) Taraf\u0131ndan kullan\u0131l\u0131r.<\/strong>
\nBirle\u015fik Krall\u0131k'ta c 7 (CCITT # 7), Common Channel Interoffice Signaling 7 (CCIS7) ile birlikte 7 numara olarak bilinir.<\/strong><\/p>\n

SS7'nin k\u0131sa tarih\u00e7esi<\/h2>\n

1960'lardan ba\u015flayarak, genel anahtarlamal\u0131 telefon a\u011flar\u0131 (PSTN) analog teknolojilerden ve ayr\u0131ca \u00e7oklu bant i\u00e7i sinyalle\u015fme y\u00f6ntemlerinden yararlan\u0131larak bir araya getirilmi\u015ftir. Yayg\u0131n sabit telefon son kullan\u0131c\u0131lar\u0131n\u0131n artmas\u0131 ve ilerleme hizmetlerine y\u00f6nelik artan gereksinim, R1 CAS gibi eski protokolleri h\u0131zla geli\u015ftirerek hizmet sa\u011flay\u0131c\u0131lar i\u00e7in cazip hale getirdi. ISDN protokol devrimi bile telekom i\u015finde bant i\u00e7i sinyalle\u015fme protokol\u00fcnden (tonlar, ses istasyonundan veya odaklanm\u0131\u015f kanaldan \u00e7al\u0131nan bitlerle) dijital ses i\u00e7in uygun mesaj tabanl\u0131 ilkellerle bant d\u0131\u015f\u0131 sinyalle\u015fmeye (ses kanallar\u0131ndan ayr\u0131lm\u0131\u015f) ge\u00e7i\u015fte b\u00fcy\u00fck bir ad\u0131m oldu\u011funu kan\u0131tlad\u0131.<\/p>\n

ISDN eski protokollerin pek \u00e7ok sorununu \u00e7\u00f6z\u00fcyor olsa da, \u00e7ekirdek sistemlerden kendi kitlesel kurulumu hi\u00e7bir zaman ger\u00e7ekle\u015fmedi ve b\u00f6ylece tedarik\u00e7ileri birbiriyle \u00e7al\u0131\u015fan (ya da \u00e7al\u0131\u015fmaya \u00e7al\u0131\u015fan) ayr\u0131nt\u0131l\u0131 bir ekipman hiyerar\u015fisiyle ba\u015f ba\u015fa b\u0131rakt\u0131.
