Channel-associated signaling (CAS) is a form of signaling used in telecommunications systems where signaling information is transmitted on the same channel as the voice data. This contrasts with common-channel signaling where a separate signaling channel is used. CAS is simpler and more widely supported in legacy systems, but it can be less efficient and flexible compared to common-channel signaling.
Business systems with such as a PBX or key system are adversely affected in incoming, outgoing call collisions and therefore require a special signaling method - Ground Start Signaling - to eliminate the chance of glare.
Bluetooth technology is the most common method of connecting a Smartphone to a PC. Wi Fi is also used and with some phones, a direct wire connection, such as USB can be used.
