... Associated Signaling (CAS) techniques and systems. However, for the past two decades, it has been replaced with Common Channel Signaling (CCS) systems. Apart from a rare trace of Signaling System No. ... (SS6) signaling, System No. 7 (SS7) is almost the exclusive CSS system; thus, CCS can almost be taken to refer exclusively to the use of SS7. The remaining sections of t...
