	Channel Associated Signaling (CAS) is a signaling protocol for the ~~setup~~ and tear-down of phone calls. It is different from other signaling protocols, such as [[SS7]] because it is not message or packet-based but rather based on bit transition for state changing, and tone transmission for information and state information exchange. In many parts of the world, CAS was first replaced by [[ISDN]] and in many cases, was ultimately replaced by SS7. Today, CAS is often used with low-density trunks.		{{DISPLAYTITLE:CAS}}
