What is ISDN and how it works?
ISDN or Integrated Services Digital Network is a circuit-switched telephone network system that transmits both data and voice over a digital line. You can also think of it as a set of communication standards to transmit data, voice, and signaling. It was designed to move outdated landline technology to digital.
What is a PSTN trunk?
PSTN Trunk is known as FXO analog line or CO line. The Public Switched Telephone Network (PSTN) is the global collection of interconnects originally designed to support circuit-switched voice communication. When you configure a PSTN trunk, you may need to configure some of the advanced settings.
What is Trunking Cisco?
A trunk is a point-to-point link between one or more Ethernet switch interfaces and another networking device such as a router or a switch. Ethernet trunks carry the traffic of multiple VLANs over a single link, and you can extend the VLANs across an entire network.
What is SIP trunk channel?
A SIP channel is the capability to support incoming and outgoing calls. Every SIP trunk contains a number of channels, which are virtual versions of telephone lines. The number of channels you need depends on how many concurrent calls your business makes.
What is trunk in networking?
What does trunk mean in networking? A trunk is a single channel of communication that allows multiple entities at one end to correspond with the correct entity at the other end. It is a “link” that carries many signals at the same time, creating more efficient network access between two nodes.
