What Is Trunk Line?

The First Customer Service Call Center

A trunk line is a high speed connection that is routed through a central office on a telephone network. A trunk line is a telephone line that is routed through a telephone carrier network and provides voice and data transfer between two parties. The trunk line today is a fiber optic line that can carry both voice and data, which is a different level of capability than the older copper lines that only carried sound or voice.

The term trunk line is used to refer to any type of telephone line that is used for home or business purposes, and it is still used today. It is not unusual to refer to each of the telephone lines that end on a teleconference bridge as trunks or trunk lines. Many businesses refer to the lines that end onto a server or an office PBX as trunks, indicating the number of lines that are available to make and receive calls at the same time.

Architecture of Network Trunks

A network trunk is a communications line that carries multiple signals simultaneously to provide network access between two points. The trunks connect the centers. The signals can convey any type of data.

A networking trunk can consist of wires, cables, and strands of fiber in a single physical cable. It can be a single link with many signals being multiplexed. The technology of VoIP converts human speech to data for transmission via the internet.

Analog telephone lines send signals to convey changes in voice. A SIP trunk is a virtual instance of a telephone line. It connects a lot of channels to a system for long-distance and international calls.

Quality of service is important to ensure voice traffic takes priority over data-intensive activities. A trunk can also include a cluster of broadcast frequencies, as in a system that allows the sharing of a few radio frequencies among a large group of users. The 1990s saw the development of trunked radio systems.

They help with the efficient use of the radio spectrum. Users are placed in logical groups rather than being assigned a Frequency. All the frequencies are pooled and computers assign broadcast channels to users.

Gitflow: A Tool for Managing Features in Software Development

The base code is the trunk in software development. The source code is known as branches. Software designers make small code changes to a single branch in the version control system in a trunk-based development model.

The baseline branch is also called the trunk. Software trunking is not a synonym for networking trunking. The infrastructure of a physical line or link can carry many signals simultaneously for network access between two points.

A development team can avoid long code integration tasks by using trunking. Changes are pushed directly to the trunk. Errors are addressed before they go live.

Project teams run unit tests to identify and resolve code conflicts. Pair programming teams review each line of work before moving to the trunk. Gitflow is a tool that manages features-based approaches to development.

Long-lived feature branches are used to maintain code changes. A developer creates a new feature branch off the trunk and works on it, then creates pull requests to get feedback from team members. Each branch is assigned a role in Gitflow.

Tie Lines: A Way to Save Money and Improve Customer Service

Second, a tie line can save money by reducing toll call costs. If two locations are located in different regions, each phone call will incur long distance charges. There is no per-call or per-minute charge after that.

The company can save a lot of money if the long distance bills are higher than the line cost. Customer service can be improved by a tie line. If a customer calls location A but actually needs to speak to someone at location B, the employee can transfer the call using the private line.
