A Class C telephone line allows which calls?

A Class C telephone line allows which calls?

• A. On-base calls only
• B. Local calls only
• C. All calls
• D. On-base and local calls

Answer: (A)

Class C lines are restricted to internal base communications. They are set up to connect phones within the installation and the base’s own network, not to off-base or civilian lines. That’s why you can use them for on-base extensions, but you cannot dial local off-base numbers or any external lines. The other options would imply access beyond the base, which isn’t permitted with this class of line.
