Question 700
At Stonebridge Research, a technician working in small-office network service desk identifies this issue: A customer receives a fiber-to-the-premises service but attempts to connect the optical fiber directly to a DOCSIS cable modem. The supporting record states that the provider hands off optical PON through an optical network terminal. The desired outcome is to choose access equipment that terminates the actual carrier medium. The goal is to restore required function without creating a new security or safety problem. How should the solution first be tested on an approved spare or pilot system?
- Connect representative powered devices to a lab switch and monitor total power budget
- Test a lab Ethernet connection after a provisioned ONT, without altering optical connectors
- Test ping between subnets through an approved router after confirming local switching
- Query a known internal name on a test client with corrected DNS settings
