An tool for you to Understand the Project 25 Standards process Assess your current equipment Identify features applicable to your requirements Design your system and/or specify equipment Develop RFP / RFQ Coordinate with your regional partners for interoperability Subscriber units only Infrastructure in the future March 2013 Project 25 Technology Interest Group 3
P25 Process Entities P25 User Needs Subcommittee (UNS) APCO Project 25 Interface Committee (APIC) Project 25 Steering Committee TIA (manufacturers) Documents P25 SoR TIA-102 Standards P25 Adopted Standards Sometimes a challenge to understand Different owners; Different purposes; Different time lines Not always in-sync March 2013 Project 25 Technology Interest Group 4
A Radio may contain All P25 services and features adopted by P25 Some P25 services and features adopted by P25 SOR features - not in the TIA 102 or P25 standard TIA102 features - not in the SOR or P25 Standard Manufacturer Specific features not in SOR, TIA or P25 PTIG Capabilities Guide provides a tool Identify services covered by published standards Plan ahead to enable interoperable implementations Inventory current system features and services ( Have ) Identify needs to for a new system ( Want ) March 2013 Project 25 Technology Interest Group 5

New in Version 1.2 1.1 released in June 2012 1.2 provides clarifications and updates Conventional Fallback Newly standardized service Affects Trunking FDMA Air Interface tables Data Overview and Specification Clarifies CAI and IP Bearer Services provided by the Packet Data Service Applicable to Conventional and Trunking applications of the FDMA Common Air Interface Clarifies several rows of the non voice service tables March 2013 Project 25 Technology Interest Group 10
Data Overview and Specification P25 FDMA Common Air Interface (CAI) Voice Service Packet Data Service P25 Packet Data Service Between mobile/portable and P25 Fixed Network Equipment (P25 FNE) PDU - Standard air interface Packet Data Units P25 CAI Data Pipe - Standard method of delivering PDUs over the air Two data bearer services IP Data Bearer Service PDU s formatted as IP Datagrams Between P25 mobile/portable and the P25 FNE FNE routes the data to the IP network, internet, etc. to its final destination. E.g. P25 Tier 2 location CAI Data Bearer Service PDU s not formatted as IP Datagrams Between P25 mobile/portable and the P25 FNE Typically terminates at a device within the P25 Fixed Network E.g. P25 Tier 1 location Some applications use either IP or CAI Data Bearer Services E.g. OTAR March 2013 Project 25 Technology Interest Group 11
