Switch jacks may also be preconfigured as what?

• A. Patch Cords
• B. Tie Switches
• C. A2 Jacks
• D. Splice Points

Answer: (B)

Switch jacks on sound-powered telephones can be wired so they serve as a bridge between two circuits. When they’re preconfigured as tie switches, the jack’s internal contacts are set up to short or connect two lines together as soon as the plug is inserted, allowing quick cross-connection without extra hardware. This is handy for routing calls or maintaining a path if one line isn’t available. External patch cords are removable leads used to connect equipment, not fixed wiring inside the jack. A2 jacks and splice points refer to different jack types or cable joins and don’t describe a built-in switching configuration.
