for advanced digital communications. In addition, NEXEDGE. is designed for self-paced migration and upgrades by offering continued service to analog fleets as long as needed and software-driven upgrades for adding advanced digital system configurations and operations. Index Advantages ...................................... . 4 .... . Technologies & Operating Modes 6 . Products & Accessories ................... 8 ................................... . Case Studies 10 Advantages Advantages Stacking up NEXEDGE. makes sound business sense Timeless Spectrum Efficiency All NEXEDGE. equipment operates in 25 & 12.5 kHz analog and 12.5 & 6.25 kHz NXDN® digital modes ° satisfying spectrum requirements today & tomorrow. Operationally Fit NEXEDGE. systems are configurable in traditional conventional, trunked and wide area trunked network operation modes. IP connectivity for NEXEDGE. trunked sites provides wide area calling and system scalability over existing private LAN/WAN assets and commercial services. Migration by Design NEXEDGE. supports both NXDN® digital and analog modes via common transceiver technology. Service to both analog and digital fleets provides a self-paced migration path that accommodates any budgetary, administrative, organizational or time constraints. NEXEDGE. uses existing power amps and site management equipment providing a return on existing investments and a choice of multiple suppliers for years to come. NEXEDGE. Conventional operates in 12.5 kHz Mixed Mode so that analog and digital fleets can share the same channel. NEXEDGE. digital trunked traffic channels can be shared with analog conventional, analog trunked or both types of traffic. Digital Voice Technology NEXEDGE. uses the AMBE+2. VOCODER, a state-of-the-art voice digitization and compression technology offering enhanced Forward Error Correction and noise reduction that offers superior clarity at varying signal strengths. 4 Secure Privacy NEXEDGE s NXDN® digital signal offers inherent security against casual electronic eavesdropping versus easily intercepted analog radio. The built-in NXDN® scrambling provides security and confidentiality for communications within the same system and talk group. Inter-site IP links are further secured through encrypted VPN tunneling. The NEXEDGE. system manager allows operators to validate/invalidate unit and group IDs for system access via IP access as fleet organization changes or as temporary or seasonal users come and go. Each NEXEDGE. subscriber radio has a factory embedded unchangeable unique one-of-a-kind Electronic Serial Number (ESN) that can be invalidated to prohibit access to unauthorized, cloned, lost or stolen radios while preserving the organization s unit and talk group ID numbering schemes. Asset Management with ROI The NEXEDGE. System Manager for NXDN® trunked sites and networks reduces operational and maintenance costs with remote programming, firmware uploading, subscriber unit privileging, monitoring and diagnostic capabilities all from a secure user-friendly Windows®-based application via direct connection, dial-up modem, or IP connection. Advantages Critical Features for Critical Jobs NEXEDGE. 65,519 ID range accommodates group and individual private unit-to-unit calling for large fleets and multi-user shared systems. The NEXEDGE. Over-the-Air Alias feature sends each user s text name over the air, providing a user friendly caller ID even if the receiving radios alias list hasn t been updated. Paging with alert provides traditional “beeper and talk back pager functionality while voice storage options allow users to recall and playback missed dispatcher voice calls. Emergency features can alert a dispatcher, a supervisor or a whole talk group to a unit in distress. The All Group Call and Broadcast Call features provide facility-wide general announcements or communications command and control during emergency evacuation or lock down procedures. Remote Stun/Kill and Revive temporarily or permanently disables lost or compromised subscriber units that may compromise security or cause system interference and Remote Check enables a dispatcher to verify if a unit is in system range. All subscribers have simult...
