FGD: Feature group D
Feature Group D is a local exchange carrier network service that, among other things, lets public-safety dispatch offices receive a 10-digit data stream, including the full call-back number, alongside wireless 911 calls. FGD is offered as a way by which wireless carriers can meet FCC enhanced 911 rules and dispatch offices can overcome their current bandwidth limits. This access group is associated with equal access arrangements, which allows the end user to have the same dialing plan (1 plus the telephone number) to reach any predetermined long distance phone companies of their choice.
