Trunks are used in telephony to connect two or more telephone systems together. They are typically used to connect a private branch exchange (PBX) to the public switched telephone network (PSTN) or to connect two PBXs together. Trunks can be either analog or digital, and they can be used to carry voice, data, or both.
Types of Trunks
There are two main types of trunks: analog and digital. Analog trunks are the traditional type of trunk and they use analog signals to transmit voice and data. Digital trunks use digital signals to transmit voice and data, and they offer a number of advantages over analog trunks, including higher quality voice and data transmission, increased capacity, and improved reliability.
Trunking Protocols
Trunks use a variety of protocols to communicate with each other. The most common trunking protocols are:
- Signaling System 7 (SS7)
- Integrated Services Digital Network (ISDN)
- Media Gateway Control Protocol (MGCP)
- Session Initiation Protocol (SIP)
Each of these protocols has its own advantages and disadvantages, and the best protocol for a particular application will depend on the specific requirements of that application.
