Hello, I'm TheManInTheBlackHat. I wanted to let you know that one or more of your recent contributions to Data terminal equipment have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. TheManInTheBlackHat  (Talk)  18:18, 24 December 2022 (UTC)

Please do not add promotional material to Wikipedia, as you did with this edit to Link layer. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not intended to be a vehicle for soapboxing, advertising or promotion. Thank you.
