Designed to replace AI's intercoms. Integrated headset-like device which has access to all department frequencies. Also let's AIs use radio on intellicard.

AI's communication can however be disabled by using intellicard option. Communication will be disabled until it is restored via intellicard again,
even if the AI is moved back into physical core. ICly it's software lock which prevents the AI from using communication circuits which are standard in all
AI cores/intellicards/etc. This does not stop AI from using intercom, however.
