I am looking for accurate and confirmed information about the MBTA EDACS EA ProVoice system. The information on this site seems to be outdated and or inaccurate. I have a P7100ip portable with ProVoice feature enabled that I am trying to program with the EDACS auto login unchecked and transmit unchecked for all talkgroups. I have programmed it with the information as it appears on this site as an EDACSip (Extended Addressing) system and I'm not having any luck. I put also put the frequencies in conventional Provoice mode to test and I am not hearing anything on the "site 33" frequencies and only short data bursts on the "site 1" frequencies. What is the current status of this system? Is it just used for AVL? It it actively in use? I am able to receive an active and pretty strong EDACS control channel.

Thanks.

Sorry, can't answer most of your questions on the system. The rapid transit lines have switched over to digital and the analog side, unfortunately is quiet. Only analog signal heard is T police. The AVI system is only used in the subway on the Green line and is separate from the radio system, it uses detectors located on the right of way to sense the signal given out by each train as to destination.
