What term describes a phone line that connects two predetermined points?

• A. Dedicated circuit
• B. Direct line
• C. Local circuit
• D. Private line

Answer: (B)

Direct line describes a connection that goes straight from one endpoint to another, without routing calls through intermediate switches to serve other destinations. This makes it the best fit for describing a phone line that connects two predetermined points, such as a station and dispatch, because the path is fixed and direct between those two sites. While a dedicated circuit or private line also implies a special, exclusive connection, the key idea they convey is exclusivity and reserved use, not necessarily the direct, two-point linkage. A local circuit is typically associated with routing within a local area and doesn’t inherently emphasize a fixed two-point connection.
