The communications box is a rectangular display window that appears on the player's HUD whenever the player's handlers or intercepted radio communication is picked up and received through the ear piece. The name of the character talking and what they are saying is then displayed for the player to view while the audio plays.
The communications box acts similar to a subtitle system but only picks up audio from the player's handlers (which the player's character hears through their earpiece) or at times it will pick up local radio conversations, usually important to the mission. The communication box typically appears on the top left side of the screen, and, depending on the information, will display an 'icon' located on the side of the box that depends on what the information regards (for example, objective-based messages appear with the 'Goals' icon).
The communications box was present in the first three Splinter Cell games, while it was removed in Splinter Cell: Double Agent (Version 1) (but made it's last appearance in Version 2). The feature was then replaced by a tradition subtitle feature in Splinter Cell: Conviction, allowing the player to simply hear dialogue from certain individuals during plot points of the game.
