1.3 DESCRIPTION OF EQUIPMENT
The Radio Communications Network consists of Base and Mobile Radio Communication
Systems (RCS). The Base RCS includes Base Data Radios (BDR) connected to wayside
Control Equipment. The Mobile RCS includes Mobile Data Radios connected to Control
Equipment on board the vehicle. The Radio Communications Systems provide bi-directional
communications. The systems operate in a combined Time Division Multiple Access (TDMA)
and Code Division Multiple Access (CDMA) environment.
The Mobile Data Radio (MDR) and Base Data Radios (BDR) in the technical manual are
Spread Spectrum non-licensed RF transceivers.
1.3.1 TYPE OF EQUIPMENT
The MDR and BDR are non-licensed spread spectrum transceivers that operate in the ISM
2400-2483.5 MHz frequency band. Antennas connected to MDR and BDR may come from
different vendors. Antennas should support the 2400-2483 MHz frequency band, be
compliant with FCC part 15 regulations, and are to be installed by professional parties.
Refer to Table 1-1 MDR/BDR Types and Applications. The following table contains part
numbers for different versions of MDR and BDR.
Part No.
Type Application
385700-1000-001 MDR Input Voltage 18-32 VDC
385700-1000-002 MDR Input Voltage 21-56 VDC
385700-3000-001 BDR Rack Mounted
385700-3000-002 BDR Wall Mounted
385700-3000-003 BDR Pole Mounted

1.3.2 PURPOSE OF THE EQUIPMENT
The radio provides a bi-directional communication link between the wayside and the vehicle
control equipment. The wayside control equipment generates data and sends it to the BDR.
The BDR transmits data over the radio channel to the appropriate MDR. The MDR
communicates with the vehicle control equipment, obtains the response, and transmits it to
the BDR via the RF link.
1.4 LOCATIONS AND DESCRIPTIONS OF MAJOR COMPONENTS
Refer to Figure 1-1 Mobile and Base Radio Assemblies and Components. The following
paragraphs contain the complete descriptions and locations of the mobile data radio and base
data radio.
