REMU discussion on the 700 system 2561 seems to indicate that Site 1 is West Orange, 22 is Ramapo, and there are sites at Telegraph Hill, Newark Court House (which is currently offline), and Jersey City. They were discussing an issue where a radio in Newark was dropping off the West Orange site and trying to go to Ramapo and Telegraph Hill but failing to fully associate. Considering the signal strength I get on Site 1 (it's the only site i can reliably pick up inside the house) it would make sense it's in Essex and even more sense that it is in West Orange.
