EADS TB5000i

Extending the Power of P25 Systems to Points Everywhere


Eads extends the power of its CORP25 ip-based radio architecture with the eads TB5000i P25 digital base station repeater. TheTB5000i is a high performance base station designed to meet the demanding needs of public safety. Some features of the of the base stations include:

  • Fully project 25 compliant
  • Conventional project 25 digital mode
  • Trunked project 25 digital mode when under the control of EADS universal site controller
  • Support the P25 fixed station interface OPEN Standard
  • Integrated IP-based digital voice and data connectivityn standard
  • Operates with eads voice over IP network and universal controllers for wide area calls
  • Transparent operation for end to end call encryption
  • Intuitive PC-based programming
  • Complete remote network management

Some of the key features of EADS' Base Station Repeaters include:

  • Interoperability over the air with P25 compliant features, including group voice calls, individual calls, talking party ID, and more
  • Interoperable with P25-compliant radios
  • Orbust, survivable design meets MIL-STD 810 C, D, E, and F specifications for fixed equipment
  • Easy installation maintenance, and software upgrades
  • Enables mooth transition from existing analog system
  • Smart network connectivity allows intelligent interfaces for conventional and trunked operation via the built-in network board
  • Provides multiple interfaces including line audio, digital inputs and outputs, and a range of external interfaces
