Is it the intention to keep the EDACS system online to serve Ulster and Dutchess county users (ie. Kingston PD and Poughkeepsie) once all Orange County government users have migrated onto the P25 system?
EDACS is not going anywhere as long as customers are still paying NYCOMCO to use the system.
The issue is specific to Orange County, where all of the frequencies used at Arden and Graham are licensed to the county under WPGP265. Those were 7 frequencies total, 4 at Arden and 3 at Graham. Without getting too into the weeds about it, at some point the county had to split the P25 system into two simulcast cells, 700 for North and 800 for South. All 7 of the frequencies in use for EDACS at those two sites would now become part of the South cell of the P25 system, requiring NYCOMCO to decide the fate of EDACS in Orange.
The first thing NYCOMCO did was to reconfigure the Arden site by moving one frequency from Schunnemunk to Arden, then moving two frequencies from Beacon to Arden. All of those frequencies are licensed to NYCOMCO. At that point, Arden was no longer using any of the frequencies licensed to the county. There are still active users in that area that rely on Arden, such as Woodbury PD.
It appears that rather than go through the trouble to reconfigure Graham, they simply shut it down entirely, as there are no active users of EDACS left in that area now.
