4.2. Fast MiniRack, TPRF31
Major TPRN Features
The TPRF31 is a low-cost mini rack which can host 2 ION-B single-slot cards, such as:
- 2 Master Optical Trx, thus being able to drive up to 8 ION-B Remote Units
- 1 Master Optical Trx (driving up to 4 ION-B Remote Units) and a proper ION-B card,
working as a Point-of-Interface (POI) towards the BTS. Please refer to fi g,.7.5
External splitting-combining modules are optionally available, thus providing a complete
solution for building simple and low-cost Distributed Antenna Systems.
Its installation-friendly brackets are suitable for both wall mounting and rack-mounting, thus
making the installation of the ION-B Fast MiniRack easy and unobtrusive.
Thanks to its RS232 / RS485 bus, the TPRF31 Fast MiniRack can be fully integrated with any
additional ION-B MiniRacks or standard racks, and managed through a full system supervision,
using the ION-B standard supervision interface. Lastly, its external dry contacts and auxiliary
inputs allow the Fast MiniRack to collect information about any external device, thus making it
into a fully environment- embedded device.
