Circuit switching is the most common technique used to build communication networks worldwide. It entails network communication where dedicated channels/circuits are established for the duration of a transmission. ISDN is a service that sends data with sound efficiently and supplies a variety of communication services via a circuit. TCP/IP combines the basic communication protocol used by the Internet and "TCP" to "IP" to call. A intraswitch trunk is a fiber-optic link that transports traffic between VLANs, with frames containing information about which VLAN the traffic belongs to. The central office switch accepts incoming calls and digitally connects to the destination.
