What information is included in a DC Comms bill?

• A. Circuits and locations
• B. Maintenance schedules
• C. Operator names
• D. Weather data

Answer: (A)

Circuits and locations are what a DC Comms bill lists. In damage control communications, the bill serves as a quick-reference map of all communication circuits—their identifiers, where they originate, the routes they take through the ship, and which spaces they traverse. This information lets responders quickly determine which parts of the ship can still communicate, identify which circuits have been compromised, and plan repairs or rerouting without delay during a casualty. It’s all about the physical topology of the ship’s communications network and where each circuit is located.

Maintenance schedules, operator names, and weather data aren’t part of this document because they serve different purposes. Maintenance schedules belong in maintenance records, operator names belong in rosters or duty logs, and weather data belongs in environmental or weather logs.
