hardware and software configuration of the SitePro Controller.

4.3 COMPATIBILITY AND MIGRATION

The SitePro Controller is compatible with Generic EDACS Trunking Card (GETC)
compatible devices with the exception of the Site Controller.

The requirements are that the SitePro Controller will only switch modes if the Control
Channel fails or a configuration command is received. The SitePro Controller will,
however, change modes as currently implemented by the GETC. For example, the
SitePro Controller Control Channel can switch modes, without failure or configuration
command, if it detects carrier.

11.DESCRIPTION

The SitePro Controller is essentially a processor with audio filtering and specialized
I/O capability. Flexibility in design allows the SitePro Controller to be configured to
function in many applications as suggested in the INTRODUCTION. Except for
Configuration Data, the SitePro Controller software is stored in flash memory.
Configuration Data is stored in NOnVolatile Random Access Memory (NOVRAM).

The Controller Board, Rockwell Modem, Analog Board, Power Supply, Display Module,
and Display Board are mounted on a tray and enclosed in a slide-out shelf (Figure 1).
The SitePro Controller shelf is a one-rack unit assembly (1.75-inches x 19-inches),
which mounts in a standard 19-inch wide equipment cabinet/rack.

Controller Board A2 uses Dual High Speed Diodes BAV99’s for lightning protection on
all RS-232C inputs and outputs. However, maximum lightning protection is achieved
when the SitePro Controller is grounded to the cabinet earth-ground using Lightning
Protection Circuitry Ground Kit 344A4500 and the Cabinet Grounding strap Kit
344A4730. Specific details for installing these grounding kits are found in the
LIGHTNING PROTECTION section LIGHTNING PROTECTION GROUNDING
of this manual.

in the hinged door. These indicators show the state of operation of the SitePro
Controller. The interpretation of these indicators depend on the system application
(refer to the SitePro Controller configuration manual for the specific application).

Green ETHERNET indicators ETH0 and ETH1 are also visible through the window in
the hinged door. These indicators indicate when something is connected to ETHERNET
1 or ETHERNET 2 ports.

MM101271V1 R1A 18

DESCRIPTION

There are six other LED indicators on the Controller Board that are not visible unless the
board is on an extender board. Yellow LED’s D7 and D10 indicate when there is
transmit activity. Yellow LED’s D6 and D9 indicate when there is receive activity.
Green LED’s D5 and D8 indicate when there is link activity (refer to the 10 Base-T

Transceiver section and the 10/100 Base-T Transceiver sections).

5.1.1.3 Rockwell Modem Interface Card Indicators

There are five Red LED indicators on Rockwell Modem Interface Card A3. These LED’s
are visible through the window in the hinged door and indicate +5V, +12V, -12V, RLDS
and CTS respectively.

5.1.1.4 Display

Eight-digit LED Display Board A6-A1 mounts between the two hinged doors on the
front panel of the SitePro Controller Shelf Assembly. Green LED D1 indicates
POWER ON to the Display Board. This display displays Channel Status and Channel
Information.

5.1.2Controls

Reset Pushbutton Switch S1 is the only control available on the front panel of the
SitePro Shelf Assembly. It is used to restart the logic of the SitePro Controller.Itis

especially useful when a circuit board has been hot swapped.

5.2ROCKWELL MODEM

The 9600 Baud Rockwell Modem Board RYTUZ 921 01/1 mounts on top of Modem
Interface Card A3 (ROA 117 2247). This Modem Board is used to generate a fast-train,
synchronous, serial data stream suitable for transmission over audio (phone) line or
microwave link. The data stream is sent to a full-duplex, four-wire, dedicated 3002 grade
telephone line.

Controller Board A2 (CB101069V1) controls the associated modem to provide a high
speed synchronous serial interface between the SitePro Controller and other EDACS
elements. Receive and Transmit Phone Data Lines are two balanced pairs carrying
Modem data to and from the station where the data is combined with station audio
(voice) and routed to the Remote Line input and Line output.

In addition to transformer isolation and conditioning provided by the SitePro
Controller, the modem provides automatic adaptive signal equalization, allowing normal
operation using input signal levels from -40 dBm to 0 dBm. The Rockwell Modem
demodulates the input signal and the resulting data is transferred using a serial interface
between the Rockwell Modem and the controller.

The modem senses a received signal by initiating a training state upon detecting an
increase in the input signal level. The modem begins processing data at the end of the
training state if the input signal is still above the nominal -40 dBm receiving threshold
value. Otherwise, the modem returns to an idle mode at the end of the training state if the
input signal is below the nominal receiving threshold value.

MM101271V1 R1A 19

DESCRIPTION

The duration of the modem training state is determined through control signals at the
time of power up. Resetting the SitePro Controller (pressing S1) or cycling the SitePro
Controller shelf operating power, initializes the Rockwell Modem for proper operation.

5.3LOW SPEED AND HIGH SPEED DATA FILTERS

The SitePro Controller has software configurable high speed and low speed data filters.
These filters are configured based on personality data.

5.3.1Low Speed Data Decode Filter

The Low Speed Data (LSD) Decode Filter, part of Analog Logic Board A4, provides
additional filtering to remove voice-audio from the receiver unfiltered audio ( vol/sq hi),
thus leaving only the low-speed subaudible data for input to the microprocessor.

5.3.2High Speed Data Encode Filter

The High Speed Data (HSD) Encode Filter, part of Analog Logic Board A4, selects only
the high-speed data (4800 or 9600 baud) from the receiver unfiltered audio (vol/sq hi).
This data can be control signaling or digital voice. The data is processed by the RF
modem and passed on to the microprocessor.

5.5COMMUNICATION LINKS

Communication Modes available to the SitePro Controller are:

1. The SitePro Controller can communicate with other devices such as the Site

Controller, IMC, and RF Station. Communication occurs primarily through an RS­232C serial interface normally operating at 19.2 kilobaud. for a SitePro Controller
interfacing with a Site Interface Module (SIM) this is set to 38.4 kilobaud.

2. The SitePro Controller can communicate with other SitePro Controllers in the
Failsoft mode of operation, over a Backup Serial Link (BSL). The link uses 0-13.8
VDC levels and operates at 19.2 kilobaud and is ordinarily used in a bus
configuration. For a SitePro Controller interfacing with a SIM this is set to 38.4
kilobaud.

NOTE

3. A timing signal called the Frame Sync Line (FSL) helps arbitrate the use of the BSL
serial bus in the Voter configuration. The FSL is also used for timing purposes. In
the the station configuration, FSL signals use 0-13 VDC levels to produce a periodic
negative going pulse.

4. A 9600/4800 baud full-duplex, synchronous communication interface over an RF
channel.

5. A 9600 baud phone line or microwave communication interface (this may be RS-232
or modem data) through a Rockwell Modem.

SitePro Controller interface functions vary from application t o application and
between EDACS systems using MASTR IIe or MASTR III repeaters. It is necessary to
refer to the Application Configuration Manual for details regarding t he specific
hardware and software configuration of the SitePro Controller.

6.0 CIRCUIT ANA LYSIS

The Theory of operation of each circuit board/card and module used in SitePro
Controller Shelf Assembly EA101209V1 is described in the following paragraphs.

Refer to the Block Diagram in Figure 2 and Outline and Schematic Diagrams as listed in
the TABLE OF CONTENTS.

The SitePro Controller is a Base Station Controller with redundant communication
links [Backup Serial Links (BSL’s)]. The BSL’s provide for inter-channel
communication with two 10Mbit Ethernet Ports. The BSL’s provide trunking
communications as well as site configuration and database messaging. One Ethernet port
is dedicated to Management System information. The second Ethernet Port is not
supported at this time.

The SitePro Controller and System Interface Module (SIM) will use the primary BSL
for trunking information and limited management system information. T he secondary
link will ensure continued trunking operation in the event of a primary BSL failure

The SitePro Controller/base station interface for digital information, both receive and
transmit, is 9.6k baud synchronous data. Additional digital control information is
provided via discrete I/O at both the base station and controller. The following diagram
(Figure 2) is a high level picture of the SitePro Controller and external interfaces.

CIRCUIT ANALYSIS

The SitePro Controller, main controller board (A2) and AMPS modem board, replaces
the CPTC GETC.
