For on-base and local calls, which line is used?

• A. Class A
• B. Class B
• C. Direct Line
• D. Class C

Answer: (B)

The line used for on-base and local calls is Class B. This type of line is designed for base-wide and nearby local communications, providing enough capacity and routing within the base’s local exchange to handle everyday voice traffic efficiently. It keeps internal traffic on the base without pulling in long-distance or external circuits. Class A lines are typically reserved for long-distance or inter-base trunks, so they’re not the most efficient choice for local calls. A Direct Line is a dedicated point-to-point circuit to a specific location, which isn’t needed for every on-base call. Class C lines serve other specialized external or non-local needs, not the general on-base local traffic.
