Actually its a whole new radio system with p25 compliant base/mobiles and all... its been a about 8 years in the making... and i believe the 1/1/13 has to do with the recent PublicSafety grant from the government to essex county new york...Why does it need to be completed by 1-1-13? There is no narrow band mandate for microwave services. Is this part of a larger project to do with narrow banding? Or just a means to connect all the other sites.
Phase II TDMA was approved over a year ago (November 2010) and Motorola has been shipping Phase II systems since August. ASTRO 25 System Release 7.11 enables Phase II on all G series base stations/repeaters and APX series mobiles/portables.Unless Essex County has been hornswoggled into being a beta test site, I doubt they will be trying to deploy Phase 2 in less than 10 months, especially as that part of the standard was only approved recently.
