Functional Description / Operation of Modules (Draft)
EXHIBIT D1-6
The main operating software for the base radio is loaded in the transceiver’s control section. As the main manager
for the base radio, the XCVR control board provides operational control over the other station modules. It handles
three types of information flow, in the following ways:
• Serves as a gateway between the network and RF functionality, by distributing the RF payload to and from
the network
• Supports operational and diagnostic functions with digital control data (for example: site information,
channel assignments, and identification numbers for call processing)
• Ensures the flow of other network management configuration information
The External interfaces include three Ethernet ports per Transceiver. Two of the Ethernet ports on the Transceiver
are used to communicate with the site controller. On single base radios these two Ethernet ports go to RJ45
connectors on the backplane. In the GTR 8000 Expandable Site Subsystem the site controller and transceiver
connect directly via the backplane. These two Ethernet interfaces also contain TDM signals which are used to
pass time reference, frequency reference and control data to the station. The third Ethernet port is located on the
front panel of the Transceiver and is used as a Dedicated CSS Port. A RS232 port also resides on the front panel
and is also used as a Dedicated CSS Port.
Additional connections located behind the Fan Module are an asynchronous port, a synchronous port, and an
alignment reference port. The synchronous port is used for V.24 application.
Inter-module communication is achieved using a Serial Peripheral Interface (SPI) bus. The SPI bus allows
communication with the slave devices consisting of the Power Supply, Receiver, Exciter and Power Amplifier
modules.
The Transceiver generates the station frequency reference which needs to be locked to one of many possible
external sources of various frequencies. The external sources can be one of the site controller 20 MHz TDM
clocks or an external reference operating at 5 or 10 MHz or 5 MHz/1pps composite signal.
Status Indicators and Buttons
There is one button on the Front Panel of the GTR 8000 Transceiver Module. This multifunction button can be
used to reset the module or to place the transceiver in an access disable mode.
The number and color scheme of the LEDs is application specific. The LEDs indicate the following states: Online,
Failure, Impaired, Booting, Lamp Test, Receiver Inhibited, Receiver Active, Illegal Carrier, Control Channel
(Operating), Control Channel (Failsoft), Service Mode, Transmitter Inhibited, Infrastructure Line Connected,
