The Scout console is the first true VoIP console system to support the Project 25 Fixed Station Interface, Messages and Procedures (TIA- 102.BAHA) standard. Audio packets from the mobile radio are transported using the P25 Common Air Interface to the base station and forwarded by Internet Protocol to the console system. The Digital Fixed Station Interface (DFSI) uses UDP, RTP and IMBE™ to transmit audio and control information over an Ethernet network.
Avtec's Scout VoIP console system supports P25 standards with interfaces that provide connectivity to conventional P25 radios using the Digital Fixed Station Interface (DFSI).
Project 25 standards meet current and future communication needs by establishing mutually agreeable migration paths for multi-vendor, interoperable communication systems. The Scout true VoIP console system supports the P25 Console Subsystem Interface (CSSI) standard to provide connectivity with Phase 1 (12.5 kHz FDMA) and Phase 2 (6.25 kHz TDMA) trunked radio networks.
The P25 CSSI driver, which is included in VPGate, connects to the Scout Trunking Gateway. The P25 CSSI driver and Scout Trunking Gateway provide the connection to a P25 Phase 1 or Phase 2 trunked radio system. Phase 1 systems operate at 12.5 kHz using FDMA. Phase 2 systems operate at 6.25 kHz using two-slot TDMA or at 12.5 kHz using FDMA.
Developed as a suite of standards for digital communications, Project 25 (P25) is an important component for most public safety and government agency communication. The standards combine requirements that meet today's public safety needs with tomorrow's needs by defining a migration path for multi-vendor, interoperable communication.
