What is a cable circuit?

Cord Circuit is a telephone exchange where the connection is completed manually, while the cords are connected to the appropriate connectors. This approach to telecommunications was historically used on the expansion plate and intersections to complete the calls until the number of subscribers to phones and progress in technology has been made obsolete. Today, computer switching has replaced this mechanical approach in most regions of the world. Some examples of cord boards can be seen in settings, such as movies and television programs set in the era where this technique was still used.

The operator sitting in the line has a number of connectors connected to local customers along with access to the trunk line to call long distances. When the customer lifts the phone, the indicator light starts and informs the operator that someone wants to complete the call. The operator connects the cable to the customer's jack and presses the speech key to speak directly to the customer and determine how to direct the call. For local calls, the other end of the cord can be connected to the PRAthe other connector. Long distance calls would require connection to the trunk line and a larger telecommunications system.

In addition to being used by telephone companies on local stock exchanges and intersections, large companies with their own private stock exchanges were also used. Such connections allowed companies to maintain a number of lines for workers and use them for both internal and external communication. The operators were available on the telephone switchboard to connect people in the office, said outgoing calls and processed incoming calls.

These circuits provided the means of calling calls in different places, but there were some restrictions. Operators have only managed to make so many calls at the same time and can be limited by available connectors or cords. As telecommunications grows in numbers, the wiring circuit was a number of obstacles. Customers could expect a non -A long time to make calls or not to place an order for the telephone service because the local switchboard could not support them. Changes in technology have led to accepting other switching techniques to complete telephone calls.

One of the notorious disadvantages of the cable circuit for customers was the ability of the operator to watch calls. This was sometimes necessary to determine when to terminate the connection or intervene in the event of a problem. This also resulted in a lack of privacy, as telephone operators could listen to discussions through the cable circuit.
