What are the best practices for installing and maintaining an outdoor phone cable?

When installing and maintaining an outdoor phone cable, it is important to bury the cable at least 6 inches underground to protect it from damage. Use waterproof connectors and junction boxes to prevent water damage. Regularly inspect the cable for any signs of wear or damage, and replace any damaged sections promptly. Additionally, avoid bending the cable sharply or placing heavy objects on top of it to prevent signal interference.
