FG-D (Feature Group D) is a type of telecommunication trunk used to provide "equal access" capability from telecommunication carriers and central offices (where the switching equipment is located and customer lines are connected and terminated) to the access tandem.

Services:
FG-D services route inter-LATA calls to the IEC point of termination (POT), route calls with a carrier access code (CAC) to the user's carrier, and pass information to the carrier. Information passed includes the caller's number, through automatic number identification (ANI). Because of its ability to pass on caller information, FG-D is proposed for use with the 911 service.
