7. Configuration
The hardware configuration, where applicable, is described in the installation section of this manual.
Hardware configuration is limited only to hardware related characteristics such as electrical interfaces.
A parameter configuration must be done to adjust each device to the user need. This procedure is
described in the manual of the configuration software. Please refers to it for more information.
A list of values for each parameter for each device is provided in a separate document on demand.
Please refer to it to set the proper value for each parameter.
To connect the PC with the configuration software to the RBS follow the procedure described in the
Local Maintenance Interface section.

8.1.1 CORE module - CORE
The CORE module, for its versatility and potentiality, is the core of ECOS-D RBS.
This module is equipped with devices for numerical computation (DSP, FPGA) and
control (microprocessor).
The primary functionalities of the Core Module are:
 MMI (Man Machine Interface) to allow an operator to interact with the
device
 Main Simulcast Management, implementing the voting algorithm,
equalization and a matrix of AF signals.
 local and remote management of the device.
The module is able to receive the input reference source from multiple clock signals:
 Internal GPS receiver (up to 2)
 AF tone (eg, tone at 3400 Hz via from an external source through LIF or DIF module)
 2,048 MHz (G.703)
The choice of input clock signal is performed according to a configurable logic that normally assigns
higher priority to the GPS signal.
The module provides as its output the following clock signals to all the other modules of the RBS:
 RBS main reference clock (26 MHz)
 PPS main and / or spare
