BR Controller (CAE010CMX)¶
This is s small PowerPC based embedded system. It communicates with the TETRA Site Controller (TSC) over 10-Base-2 Ethernet and controls all the other units of the Base Radio via the backplane of the BR cabinet.
It has the following connections:
- RS-232 on the back of the BR
- RS-232 on the front of the BR
- Site Alarm I/O on the back of the BR
- 10-Base-2 Ethernet on the back of the BR (BNC)
- Clock input on the back of the BR (BNC)

Hardware¶
The hardware is a typical embedded design centered around MPC860 PowerPC:- XPC860DECZP33C1 (MPC860 PowerPC SoC)

- Hardware Specs: http://cache.freescale.com/files/32bit/doc/data_sheet/MPC860EC.pdf
- BDM/JTAG: http://cache.freescale.com/files/netcomm/doc/app_note/AN2387.pdf
- Seems like P3 is the BDM/JTAG port for it
- 4x AM29LV017D (16MBit NOR Flash), total capacity = 8MByte
- CT2M64S4D10.8T66 (16MByte SDRAM module)
- NE83C92A coaxial Ethernet transceiver
- XC56307GC100E (24-bit DSP56307 Digital Signal Processor)
- http://www.datasheetcatalog.org/datasheet/motorola/DSP56307.pdf
- Seems like P1000 is the OnCE/JTAG port for it
Software¶
boot loader¶
There is a bootloader pre-installed in the Base Radio.
radio application¶
It seems like the BR Controller is downloading its software via the Ethernet link from the [Dimetra_EBTSSite_Controller]
Console logs¶
Normal boot¶
During normal boot, the console output is as follows:
RAM Test: .... passed Base Radio Controller Version R07.00.20 Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000 Motorola Inc. All rights reserved. Ethernet Test: passed Running from boot code area To enter configuration mode, hit any key within 10 seconds: Starting BRC registration Waiting for Registration Waiting for Registration Waiting for Registration Waiting for Registration Waiting for Registration Waiting for Registration
where at the end it is probably waiting to register with the [Dimetra_EBTSSite_Controller]
configuration mode¶
If the boot process is interrupted, you get into configuration mode:
