4.1APPLICATIONS
The SitePro Controller can be installed and programmed for several different station
applications. The basic programming is for the Station Trunking Shelf. This shelf
enables the station to function as part of an EDACS trunked communication system by
providing digital signaling and transmitter control of the associated base station. In
addition, the SitePro Controller provides an interface between the base station repeater,
the Site Controller or Site Interface Module (SIM) and other channel SitePro
Controller(s) at the same time.
By reconfiguring the SitePro Controller shelf hardware and programming the operation
through the programming port, located on the front panel, the SitePro Controller can be
used as an/a:
•Uplink/Downlink – Configured as either an Uplink or Downlink, the SitePro
Controller provides the communications link between the Transmit Site and the
CEC/IMC switch.
2The Service Technician(s) should always consult application manuals, Software Release Notes (SRN), and Specific
Customer information provided with the system whenever the equipment requires service or repair.

4.2COMMUNICATIONS
The following communication modes are available:
1. The SitePro Controller can communicate with Personal Computers (PC’s) through
ethernet ports J5 and J6.
2. The SitePro Controller can communicate with other devices, such as Site
Controllers or the CEC/IMC switch, through the Serial Ports at J14, using an RS-232
serial data format operating at 19.2 kilobaud. Connector J14 provides connection to 6
telephone lines and 6 serial ports.
3. The SitePro Controller can communicate with other SitePro Controller(s) in the
Failsoft or Enhanced mode, over two Backup Serial Links (BSL)ortwoRockwell
Modems (RM’s) through connector J4. This link uses 0-13.8 VDC levels at 19.2
kilobaud.
4. The SitePro Controller uses the Frame Sync Line (FSL), also through connector
J4, to communicate timing between SitePro Controllers. This line uses a 0-13.8
VDC bus that carries a periodic negative pulse.
5. A 9600 or 4800 baud full-duplex, synchronous communication interface over an RF
Channel.
6. The SitePro Controller can use synchronous modem data to communicate with
other sites via telephone lines or microwave links.
7. The SitePro Controller interfaces with an Enhanced Digital Access Communication
System (EDACS) through 24 Pin connector J12.
8. Power is connected to the SitePro Controller through 4 Pin POWER connector J7.
3 Installation and configuration of Simulcast SitePro Controllers is documented in a specific Simulcast Application Manual.
MM101271V1 R1A 11
9. The SitePro Controller interfaces with a Conventional MASTR III base station or
Digital Signal Processor (DSP) through 20 Pin CONV/DSP connector J11.
10. The SitePro Controller interfaces with a GPS Simulcast system through 26 Pin
SIMULCAST connector J13.
NOTE
SitePro Controller interface functions vary from application to application and
between EDACS systems using MASTR II or MASTR III repeaters. It is necessary to
refer to the Application Configuration Manual for details regarding the specific
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.
For High Speed Data Modulation,theSitePro Controller has a separate Analog Board
(A4) providing software configurable filtering, which is compatible with high speed data
types.
4.4 SYSTEM EXTERNAL INTERFACES
(SitePro Trunked Interface Specification)
The following is a description of all electrical connections to the SitePro Controller.
All input/output definitions are relative to the SitePro Controller. This configuration

DESCRIPTION
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.
5.1INDICATORS AND CONTROLS
This section describes the indicators and controls visible and accessible from the front
panel of the SitePro Controller Shelf Assembly.
There are two hinged doors on the front panel of the shelf assembly. Each door has a
window so that indicators mounted on Control Board A2 and Rockwell Modem Interface
Card A3 can be seen. Opening the Control Board door provides access to Reset
Pushbutton switch S1. This door also provides access to PROGRAMMING SERIAL
PORT J8. The circuit boards can be removed from the shelf assembly through these
doors. An extender card can be inserted providing access to a board in a hot system.
5.1.1 Indicators
5.1.1.1 Controller Board Power Indicator
Green LED indicator D12 provided on the Controller Board indicates when power is
applied to the shelf. This indicator is visible through the window in the hinged door on
the front panel of the shelf.
5.1.1.2 Controller Board Status Indicators
Four Red LED status indicators L1 thru L4 (D1 thru D4) are visible through the window
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 RS-
232C 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.
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.
NOTE
SitePro Controller interface functions vary from application to 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 the specific
hardware and software configuration of the SitePro Controller.

CIRCUIT ANALYSIS
6.0 CIRCUIT ANALYSIS
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. The 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.
The SitePro Controller, main controller board (A2) and AMPS modem board, replaces
the CPTC GETC.
6.1SHELF ASSEMBLY
SitePro shelf Assembly EA101209V1 is a 19” Rack Mount, one Rack Unit device. It is
enclosed to reduce emissions and interference with other devices. Serial, Ethernet,
power, and I/O connections are accessible at the back of the shelf (Figure 1). The Serial
connections (6 OVER 6 PHONE LINES & SERIAL PORTS) are stacked, two high
using RJ type connectors (J14). The Ethernet connectors J5 & J6 (ETHERNET 0 &
ETHERNET 1) are single height RJ connectors. The power connector (J7) and I/O
connector (J#) are Molex type.
The front panel has two hinged access doors for insertion/removal of the Controller
Board and the Rockwell Modem card for troubleshooting and ease of maintenance.
These doors have RF fingers to reduce emissions. Diagnostic LED’s and the eight-digit

6.2INTERCONNECT BOARD (A1)
Interconnect Board CB101073V1 is a passive printed circuit board that provides
interconnections between all internal components of the SitePro Controller shelf and
interfaces the SitePro Controller shelf with the outside world (Refer to Table 3 -
Interface Connections, and Interconnection,Outline and Schematic Diagrams). Pi
filters U1 thru U29 eliminate any Electro Mechanical Interference (EMI).

CIRCUIT ANALYSIS
6.2.1 Oscillator For Ethernet PHY’S
This circuit consists of crystal oscillator circuit Y1 powered by 3.3 V applied to Y1, Pin
4, Vcc. Oscillator circuit Y1 is biased on by resistor R49 connected to Y1, Pin 3, CTRL
and produces 25 MHz on the output at Pin 3 through resistor R51 (OSC 25MHz). This
output connects to the CLK25 inputs to the Ethernet 10 and Ethernet 10/100 Mbit
PHY’s4.
6.2.2 JTAG Port
This JTAG PORT circuit consists of buffer U1 (NC7SZ125M5). This circuit allows
programming directly to a microprocessor through connector J4.
The JTAG port is also routed to the Modem Daughterboard. This allows a future modem
daughterboard to be designed with an Altera EPLD. If that future EPLD modem
daughterboard is used, resistor R187 (0 ohms) must be removed from the board.
6.3.2.3.1Board Insert Detection Circuit
This circuit consists of NPN transistors Q6 and Q7. When the Controller Board is
inserted into a live Interconnect Board, the base circuits of these transistors are
connected to ground through connector J1B, Pins B1 and B32. Connector J1B, Pin B1 is
MATE-DETECT-A and J1B, Pin B32 is MATE-DETECT-B. With the base of both
transistors at ground, they are held in the off state. This allows POWER ON to cycle
high and low as the result of 555 timer U40 running at a programmed rate. The POWER
ON voltage is applied to Pin 2 of Hot SwapTM Controller U37. If the base of either
transistor (Q6 or Q7) is not connected to ground, POWER ON will not be applied to the
HotSwap Controller.
6.2.4 Hot Swap™ Controller
Hot Swap™ controller (HSC) U37 allows Controller Board CB101069V1 to be safely
inserted in or removed from Interconnect Board CB101073V1 while voltage is applied.
Using external N-channel pass transistor Q5, the supply voltage to the Controller Board
is ramped up at a programmable rate. A high side switch driver controls the N-channel
gate for supply voltages ranging from 2.7V to 12V. A programmable electronic circuit
breaker protects against shorts. The RESET output (U37, Pin 1) is used to generate a
system reset when the supply voltage falls below the programmable voltage. The
POWER ON input to U37, Pin 2 is used to cycle the Controller Board power or to
generate a soft reset.
6.2.5 3.3V Regulator
The microprocessor is provided with 5 Volts and ±12 Volts from the Interconnect Board.
Linear regulator U25 is used to provide 3.3 volts to be used by the majority of digital
logic on the Controller Board and the Daughter Board.
The Hot Swap Controller (HSC) is used to ramp up the 5V power rail at a controlled
rate. This, in addition to other considerations, will allow the Controller Board to be hot-
swapable. The 5V output from this circuit will also power the 3.3 Volt regulator, thus
4 PHY is an Industry Standard for “Physical Interface.”
MM101271V1 R1A 30
CIRCUIT ANALYSIS
causing the 3.3 V power rail to also ramp up at a controlled rate. As mentioned above,
the HSC has a built-in electronic circuit breaker. The 555 timer circuit (U40) is
connected to the HSC chip so that the HSC can be automatically reset in the case of a
circuit breaker fault.
6.2.6 3.3V Power Monitor
The 3.3V Power Monitor (U31) uses a precision temperature-compensated reference and
comparator circuit to monitor the status of the 3.3V supply. If a loss of power is detected
an internal power-fail signal forces reset to the active state, which is low. When the 3.3V
supply returns to a normal state, the reset signal is kept active for approximately 150 ms
to allow the power supply and microprocessor to stabilize. This 3.3V Power Monitor
circuit also monitors Reset Pushbutton S1 on the reset output, U31, Pin 1. If the reset is
pulled low, by pressing S1, a reset signal is generated upon release. The output of U31 is
held in reset output (low) for approximately 150 ms.
6.2.7 Test Points
Test Points TP1 thru TP10 are provided on the Controller Board as follows:
•TP1 thru TP3, TP7, TP8 and TP10 are ground connections
•TP4 is +12V
•TP5 is +3.3V
•TP6 is +5.0V
•TP9 is WALSHCLK
•
••
•Programming Serial Port J8
This port (J8) is located at the front of the Controller Board just behind the hinged door.
It is provided so that a programmer can easily program the microprocessor from the front
of the SitePro Controller without removing it from the cabinet.
6.2.9 Decouplers
Decoupling capacitors (Decouplers) are used to eliminate high-speed transient noise in
high-speed digital circuits. There are a number of decoupling capacitors used on the
Controller Board. On sheet 3 of Schematic Diagram WD-CB101069V1 there are two
3.3V decoupling capacitors, C2 and C87. On sheet 5 there are three 3.3V decoupling
capacitors, C62, C83 and C113. There are also six 5.0V decoupling capacitors on sheet
5, C52, C74, C103, C104 and C110. On sheet 6 there are four 5V decoupling capacitors,
C69, C81, C102 and C109. On sheet 7 there are three 5V decoupling capacitors, C76,
C92 and C101. On sheet 9 there are ten CPU DECOUPLING CAPS, C8, C11, C12, C16,
C27, C28, C39, C48, C51 and C71. On sheet 11 there are ten 3.3V decoupling
capacitors, C26, C38, C61, C67, C76, C88, C89, C98, C99 and C100. There is also one
5.0V decoupling capacitor on sheet 11, C55. On sheet12 there are ten 3.3V decoupling
capacitors, C29, C30, C33, C34, C37, C40, C43, C58, C59 and C50. On sheet 13 there
are ten 3.3V decoupling capacitors, C3, C4, C6, C7 C9, C13, C17, C22, C23 and C24.
On sheet 14 there are three 5V decoupling capacitors, C64, C70 and C86. On sheet 15,
there are five decoupling capacitors, C1, C5, C15, C18 and C21. On sheet 16 there are
MM101271V1 R1A 31

five 3.3V decoupling capacitors, C32, C36, C42, C47 and C56. On sheet 17 there are
four 3.3V decoupling capacitors, C77, C90, C91 and C105.
6.3.3Blackplane
The Controller Board to Interconnect Board A1 (Backplane) connector circuits are
shown on Schematic Diagram WD-CB101069V1, Sheets 4-7 and include:
•Board Connections •I/O (1)
•Serial I/O •I/O (2)
6.3.1 Board Connections
Schematic Diagram WD-CB101069V1, Sheet 4 shows the single DIN96 connector, J7.
This 96-pin connector has three layers of pins, J7A, J7B and J7C. Each layer consists of
32 pins. J7B, Pins 1 and 32 are the MATE-DETECT-A and MATE DETECT-B
connections. These two connections are used with the Board Insertion Detection circuit.
Pins J7B; Pins 27 and 28 are the SCL and SDA connections. SCL and SDA make up the
I2C bus. CPU I/O SIGNAL PROTECTION DIODES D27, D29 connected to SCL and
SDA provide lightning protection for the I2C bus.
6.3.2 Serial I/O
Numerous asynchronous and synchronous serial ports are brought to the Interconnect
Board (Backplane) from the microprocessor, Modem Daughter Board and QUART.
Most serial ports convert to standard RS-232 levels using RS-232 transceivers U13, U24,
U30 & U36. Serial port U21 converts to RS-485 differential signal levels and supports a
multidrop network. One microprocessor RS-232 port is intended to be used as a
diagnostic or local programming port and will be brought to RJ-11 connector J8 on the
front of the board in addition to the I/O Interconnect Board. Two ports from the QUART
use BSL signaling.
All Serial ports are designed for full-duplex 115.2 kbaud communications with the
exception of the RS-485 port U21 from the microprocessor SCC. This port is a half-
duplex HDLC port and supports speeds up to 2 Mbaud.
U21 is a differential bus transceiver for bi-directional data communication on multiport
bus transmission lines. This device combines a 3-state differential line driver and a
differential input line receiver. The driver and receiver have active-high and active-low
enables that are connected together externally to function as a direction control. The
driver differential outputs and the receiver differential inputs are connected internally to
form differential input/output I/O bus ports. These ports are designed to offer minimum
loading to the bus when the driver is disabled or Vcc=0.
BSL signaling is accomplished through two identical circuits consisting of hex inverting
Schmitt Triggers U23A/U23B, inverter buffer drivers U35A/U35B, Field Effect
Transistors (FET) Q3/Q4, amplifier transistors Q9/Q10 and diodes D23/D25. Inputs to
the microprocessor from the Interconnect Board (backplane) are through diode D23/D25
to the input of U23A/U23B. Schmitt Trigger U23A/U23B provides a well-defined output
for an input to the base of amplifier transistor Q9/Q10. The output of Q9/Q10
(RXA/RXB) is applied to the microprocessor. When the input (BKP-BSL0/BSL1) is
high, diode D23/D25 is reversed biased making the input to U23A/U23B high and the
output on the collector of Q9/Q10 also high. When the input is low, diode D23/D25 is
32 MM101271V1 R1A
CIRCUIT ANALYSIS
forward biased and the input to U23A/U23B is low. The output on the collector of
Q9/Q10 is also low.
Outputs from the microprocessor to the backplane are through inverter buffer driver
U35A/U35B, and FET Q3/Q4. The output RXA/RXB from the microprocessor is applied
to the input of inverter circuit U35A/B35B. When this input to U35A/B35B is low, the
output is high. This causes Q3/Q4 to conduct. Diode D32/D33 is forwarded biased and
the output to BKP-BSL0/BSL1 is low. When the input to U35A/U35B is high Q3/Q4
does not conduct and the output to BKP-BSL0/BSL1 is high.
6.3.3 I/O
Other I/O’s are shown on Schematic Diagram WD-CB101069V1, Sheets 6 and 7. Inputs
to the microprocessor from the backplane consists of identical circuits for different
inputs. These circuits consist of inverter buffer driver circuits U18A thru F, Schmitt
Triggers U22B thru D and U23C thru F (Figure 4). Identical circuits for different inputs
also include inverter buffer driver circuits U22A thru F, U29D and U32B (Figure 5).
In Figure 4 when the input from the backplane goes low the diode is forwarded biased
and the input to the inverter goes low. This results in a sharp, well-defined output of the
inverter going high. Outputs are:
•REM-AUDIO PRESENT (U18A) •EXTADIN (U22C)
•CAS (U18B) •EXT150IN (U22D)
•CGMON (U18C) •RCVING-FROM-AV (U23C)

6.3.4CPU
The Central Processing Unit (CPU) circuits for the Controller Board are shown on
Schematic Diagram WD-CB101069V1, Sheets 8 & 9 and include:
•Microprocessor •Microprocessor Support
6.3.4.1 Microprocessor
Microprocessor U9A is a Motorola MPC860P processor that has four SCC channels, two
SMC channels, plus a 100 Mbit Fast Ethernet Controller. One of the SCC channels is
used as a second ethernet port (10 Mbit) with all other SCC and AMC channels used as
serial ports.
This microprocessor runs at 59 MHz using a 29.4912 MHz clock input. This frequency
was selected for use by the baud rate generators to produce standard baud rates up to
115.2 kbaud without error. The microprocessor external bus runs at half the speed of the
microprocessor (29.5 MHz).
The microprocessor provides a real-time clock that is used to provide time-of-day
information to the application software. The real time clock runs off of a 32.768 kHz
crystal and is provided with 3.0 Volt battery voltage via the KAPWR pin of the
microprocessor to keep time when power is off.
Four external interrupts are used in this design. The remaining unused three connect to
the EPLD for future use. Connecting them to the EPLD makes later modifications easier.
The external interrupt signals are specified in the following table.

Note that there is both a 32-bit data bus and an 8-bit data bus. The 8-bit data bus is
connected to the 32-bit processor data bus via an 8-bit transceiver. The output enable for
the transceiver is controlled by ANDing all 8-bits chips selects together inside the EPLD.
6.4.2 Microprocessor Support
The microprocessor support as shown on Schematic Diagram WP-CB101069V1, Sheet 9
includes:
•BDM Debug Port Connector •Silicon Serial Number
•Power-On Reset Configuration •KAPWR Switch
•32 kHz Crystal •8-Bit Bus Transceiver
•VDDSYN Filter •MICTOR Logic Analyzer Connectors
BDM Debug Port Connector
For support, microprocessor U9A provides a dedicated serial port (BDM) for connecting
a debugger/emulator. A debugger/emulator connected to this port allows a programmer
to read/write registers and external peripherals, control program execution, etc. Many
debuggers also have built-in capability to program on-board flash through this port.
These serial port pins are brought to 10-pin header J1 using the standard BDM pinout
Power-ON Reset Configuration
The Power-On Reset Configuration consists of four octal buffer/drivers U6A, U6B, U8A
and U8B with 3-state outputs. This circuit ensures that at Power-On all circuits are reset
to the starting state. Inputs to these circuits are through 10K BUS8 resistor networks
RN7 and RN10. The outputs tie into bus D[0.31]. Each package is organized as two 4-bit
line drivers with separate output-enable (OE) inputs. These inputs are tied together and
connect to RESET-N. When RESET-N is low, data passes from A inputs to Y outputs.
When RESET-N is high, the outputs are in the high-impedance state.
32 kHz Crystal
This crystal circuit consist of crystal package Y3, resistors R90 and R98, capacitors C49
and C63. This circuits connects to U9A between pins N1 (EXTAL) and P1 (XTAL) and
produces an oscillator frequency of 32.768kHz to drive the real-time clock.
5 UPMB is only required if the system makes use of the BUSY_N signal coming from the dual port memory. If BUSY_N is
not used, then a GPCM machine can be used for this chip select.
MM101271V1 R1A 37
CIRCUIT ANALYSISN
29 MHz Clock
The 29 MHz Clock consists of oscillator circuit Y2 and resistors R82 and R105. This
circuit produces the oscillator frequency of 29.4912 MHz and connects to U9A at N2
(EXTCLK).
VDDSYNC Filter
This circuit consists of inductor L1 and capacitors C50 and C57. It connects between the
3.3V supply and the VDDSYN connection through capacitor C68 to microprocessor
U9A, Pin T2 XFC. The primary purpose of this circuit is to
Silicon Serial Number
A unique 64-bit electronic Serial Number chip U3 is used to store the board
identification number. This chip has a 1-bit serial port, which interfaces to
microprocessor U9A through an I/O port. In addition, four bits of hardware identification
are made available to U9A through I/O ports. The Hardware ID is changed based by
selectively populating a bank of resistors.
KAPWR Switch
The KAPWR switch consist of Schottky diodes D30 and D31 and battery BT1. This
switch applies 3.3V supply or 3.3V battery to U9A, Pin KAPWR
8-Bit Bus Transceiver
This circuit consists of 8-Bit Bus Transceiver U19 and resistor network RN15. The 8-Bit
Bus connects to the microprocessor through 8-Bit Bus Transceiver U19. The output
enable OE for the transcreiver is controlled by ANDing all 8-bit chip selects together
inside EPLD U27.
MICTOR Logic Analyzer Connectors
These connections consists of J3, J5 and J6.
6.3.5Modem Daughter Board Connector
The Modem Daughter Board connector circuits for the Controller Board is shown on
Schematic Diagram WD-CB101069V1, Sheet 10 and include:
•QUICC Connector (J1) •I/O Connector (J2)
6.5.1 QUIC Connector (J1)

CIRCUIT ANALYSIS
6.5.2 I/O Connector (J2)
The I/O (J2) connector has miscellaneous I/O to/from the EPLD or Interconnect Board
(Refer to the Modem Daughter Board Section).
6.4.5Electrically Programmable Logic Device (EPLD)
The EPLD circuit for the Controller Board is shown on Schematic Diagram WD-
CB101069V1, Sheet 11.
Access to various board inputs/outputs is made available through Electronically
Programmable Logic Device (EPLD) U27. The EPLD contains numerous read/write
latches with a simple 8-bit interface to the microprocessor.
The EPLD is in-circuit programmable via the JTAG port using an Altera byte-blaster
cable. A 10-Pin header is made available for this purpose. The EPLD JTAG port is also
brought to microprocessor I/O pins to allow the microprocessor to load the EPLD
configuration.
In addition to being an interface to the discrete I/O, the EPLD also divides clocks and
provides the output enable logic for the 8-bit data bus transceiver.
6.7 Ethernet Ports
There are two Ethernet Port circuits for the Controller Board and they are shown on
Schematic Diagram WD-CB101069V1, Sheets 12 & 13 as:
•10 Base-T (10 Mbit PHY) •10/100 Base-T (10/100 Mbit PHY)
The 10/100 Mbit port (10/100 Base-T Transceiver U5) uses the Fast Ethernet Controller
inside the microprocessor and supports full duplex (10/100 Base-T). The 10 Mbit port
(10 Base-T Transceiver U12) uses SCC1 and only supports half-duplex (10 Base-T). The
ethernet physical layer transceivers are the same for both ports, but the 10/100 Mbit port
uses the MASTR II interface whereas the 10 Mbit uses a “7-wire” interface. The ethernet
transceivers support 10/100 Base-T with full auto-negotiation capability, while the 10
Mbit port only advertises 10 Mbit capability.
The RJ-45 ethernet connectors are actually located on Interconnect Board A1
(Interconnect Board). The ethernet physical layer chips and transformers reside on the
Controller Board with the ethernet differential RX/TX signals brought to the RJ-45
connectors through the Interconnect Board connector. A single LINK OK status LED is
provided for each ethernet port on the front of the Controller Board.
The 10Mbit Ethernet port uses the “7-wire” interface to connect the Ethernet physical
transceiver to the microprocessor SCC1 serial channel. When SCC1 is in Ethernet mode,
the SCC pins have different functions (refer to the following table).
Table 6 - 10 Mbit Ethernet Connections

In order to use both the SCC1 in Ethernet mode and I2C bus, the board software applies a
small microcode patch at startup. This relocates the affected overlapped registers. Make
sure to use the new register addresses in the code. To obtain the patch, go to:
http://www.mot.com/SPS/ADC/pps/subpgs/etoolbox/8XXX/i2C_spi.html.
6.4.6I2
C Bus
The I2C-bus is a two-wire serial bus (SCL and SDA) used for microcontroller-based
control. The I2C Bus circuits for the Controller Board are shown on Schematic Diagram
WD-CB101069V1, Sheet 14. These circuits consist of Personality EEPROM U14, and 8-
bit I/O expanders for the I2C bus U15 and U26.
32k of non-volatile data storage is provided by EEPROM U14. EEPROM U14 is
organized as 32kx8 and is accessible via the I2C port of microprocessor U9A.
Serial EEPROM U14 has a write protect pin. It is active high and has an external pull-up
to always make it active. To write to U14, port PB23 on the microprocessor is defined as
an output and driven low. To write protect the EEPROM after writing to it, port PB23 is
defined as an input and the pull-up activates the write protect signal.
Several peripherals are available to the microprocessor through the I2C Bus. In addition
to a 32kbyte EEPROM, there is an 8-bit writable latch for driving 4 LED’s and an 8-bit
readable latch for reading the status of an 8-bit DIP switch. The I2C bus is also brought to
the Interconnect Board for accessing other off-board peripherals (i.e. LED display). I2C
bus addresses are as follows:

6.9.2 FLASH
Two flash memory modules U10 and U11 are organized as 1M x 32 for non-volatile
program storage (Flash). These two modules have 4 Mbytes of flash memory with the
ability of expansion up to 8 Mbytes. The program execution takes place directly from
flash so that performance is as important as is the ability to load new code while in the
lab and while in the field.
6.9.3 Quad UART
The QUART circuit for the Controller Board is shown on Schematic Diagram WD-
CB101069V1, Sheet 17.
Universal Asynchronous Receiver-Transmitter (UART) U28 is used to handle
asynchronous serial data communication. Asynchronous means that the data is not
synchronous, that is, it is not occurring at a steady constant rate, but is being transmitted
intermittently through serial ports. In data transmission, serial means, transmitting one
bit at a time.
The serial port is a general-purpose interface that conforms to the Recommended
Standard–232C (RS-232C) and can be used to interface with almost any type of device
(modem, mouse and serial printer, etc.).
MM101271V1 R1A 41
CIRCUIT ANALYSISN
Quad UART (U28) is accessible to microprocessor U9A for four additional serial ports.
QUART U28 runs off 3.3 volts, forcing the microprocessor interface to be asynchronous
and run at 14.75 MHz, the microprocessor bus clock divided by 2 inside the EPLD. The
communication clock input will be 3.6864 MHz, the microprocessor bus clock divided
by 8 inside the EPLD. None of the I/O ports of the QUART will be used, but the ports
are connected to mod points in case of a later use.
The QUART uses two chip selects, CS2 and CS3. Chip select CS2 is used when
accessing the QUART registers. Chip select CS3 is used after an interrupt to read the
interrupt vector.
6.5 MODEM DAUGHTER BOARD
The Modem Daughter Board contains three synchronous serial ports (modems) and a
local microprocessor. This board plugs into the Controller Board using two connectors,
QUICC (J9) and I/O (J2). Refer to Figure 4 – Modem Daughter Board Block
Diagram.
The microprocessor interface is a simple 8-bit asynchronous port with two separate chip
selects. One chip select controls access to an 8k x 8 dual port RAM. The other chip
select controls access to the Modem Daughter Board microprocessor local memory. The
Controller Board microprocessor loads the Modem Daughter Board local memory with
code before releasing the Modem Daughter Board reset. The Modem Daughter Board
microprocessor runs from a 14.7 MHz clock generated by dividing down the 29.5 MHz
Controller Board microprocessor output clock inside the EPLD.
Circuits for the Modem Daughter Board are shown on Schematic Diagram WD-
CB101074V1, Sheet 1. The Outline Diagram is shown on PS-CB101074V1.
Modem Daughter Board CB101074V1 mounts on the Controller Board and exists
primarily to support Modem chips, U9, U10, and U11. These modems process 9600 baud
serial synchronous receive and transmit data from the RF path (U9), the Phone Line
(PL) path (U10) and the Voted Digital Interconnect (VDI) path (U11).
Microprocessor U1, a Dallas 80C323, controls the three modem chips, generates the
transmit data, and processes the receive data for use by the system.
The microprocessor communicates with the QUICC processor on the Controller Board
via Dual Port RAM U3.
There is no non-volatile memory on the Modem Daughter Board. Code is loaded into
Code RAM (U2) via an interface from the QUICC processor.
Most of the circuitry on the Modem Daughter Board operates from a 3.3V supply. The
Modem chips, however, require 5V. Thus a 3.3V to 5V conversion (U6) is needed for all
signals to the Modem chips.

CIRCUIT ANALYSIS
6.1 Modems
Each Modem chip interfaces to the 80C323 microprocessor via an 8-bit bi-directional
address/data bus, and Chip Select (CS/), Read (RD/), Write (WR/), ALE, and Interrupt
(INT/) signals.
During transmit, the microprocessor writes data to the Modem as requested by the
Modem interrupt. The Modem converts the data to a 9600 baud synchronous serial data
stream.
During receive, the Modem chip receives the 9600 baud synchronous serial data stream
and interrupts the 80C323 microprocessor whenever it has a complete byte to transfer.
The modem must also acquire bit sync and word sync from the data stream.
6.2 3.3V/5V Interface
Because the Modems require a 5V supply, and the microprocessor is on a 3.3V supply, it
is necessary to convert the voltage of signals passing between them. This is done by U6,
an IDT74FCT164245 3.3V/5V converter. Both output enable and direction can be
controlled for the two 8-bit sections of this IC.
In this case, the outputs are always enabled, so the OE/ pins are tied low. Section 1 is
used for signals, which only go from the microprocessor to the Modems, so Pin 1 (1DIR)
is tied high. Section 2 is used for the bi-directional bus. Pin 24 (2DIR) is driven by logic
which sets the direction from microprocessor to Modems (high) most of the time. Only
during a read of one of the microprocessors is the direction reversed (low).
6.3 Microprocessor
The 80C323 microprocessor is a 3.3V version of the Dallas Speedy micro, an 80C32
derivative. It operates on a 14.7462 MHz. Clock, which is convenient for generating
standard baud rates. It interfaces with the Modems, Code RAM, Dual Port RAM, and
Data RAM via standard address and data busses.
The microprocessor has 2 asynchronous serial ports (TXD0/RXD0 and TXD1/RXD1)
which may be used in the SitePro system for diagnostics. Both ports are available on the
rear of the SitePro shelf.
Six bits of 80C323 microprocessor I/O are used in a SitePro configuration. WALCLK,
WAL1, WAL2, and HSACQCTL are outputs, while LSRX and MODFSL are inputs.
The microprocessor has only two level sensitive interrupts, INT0/ and INT1/. The first,
INT0/, is used for all Modem interrupts. The second, INT1/, is used for interrupts from
the Dual Port Ram.
Since it is still necessary to distinguish between the three Modem interrupts, RFINT/ and
PLINT/ are brought to I/O pins so the microprocessor can easily determine which
Modem is interrupting. i.e. If a Modem interrupt occurs, the microprocessor looks at the
two pins. If either or both are low, the corresponding interrupts are serviced. If neither is
low, the VDI interrupt is serviced.
The 80C323 (U1) uses standard Intel multiplexed address/data bussing. During the first
half of the bus cycle, U7 latches the lower 8 bits of address under the control of ALE.

6.4 Code Memory
Code is stored in 128K byte RAM U2. The microprocessor can then access it via the
Address and Data bus using PSEN/.
Code is loaded into U2 from the QUICC microprocessor. During loading, the QUICC
holds the 80C323 reset with the RESETIN/ (low) signal. This is required so the 80C323
will not try to access U2 at the same time causing bus contentions. During loading, bus
transceivers U12 (address bus) and U13 (data bus) are turned on. They are held inactive
at all other times by the same RESETIN/ signal.
The QUICC controls Code memory access through signals RESETIN/, R/WL, CODECS/
and CODE_A16. While RESETIN/ is held low, the QUICC can write or read U2.
CODE_A16 can be used to control which 64K byte half of U2 is used. Thus, for
instance, Control Channel code could be stored in one half and working channel code in
the other. The switch is performed while the 80C323 is held reset, so it is entirely
transparent to the 80C32.
When RESETIN/ is high, the bus transceivers U12 and U13 are off and the 80C323
controls the bus.
6.5 Data Memory
Data is stored in 128K byte RAM U4, however, only 32K is used. Chip select is A15/,
thus the RAM is addressed in the upper half of memory space.
6.6 Dual Port Ram
Dual Port RAM U3, an IDT70V05 8K byte device, is the communication path between
QUICC and 80C323 during normal operation. Either microprocessor can read or write
any location in the RAM. Protocols must be established in software to avoid contention.
The QUICC can interrupt the 80C323 by writing to Address ______. This causes
interrupt line INTR/ to go low. It is cleared by a read of the same address by the 80C323.
Likewise, the 80C323 can interrupt the QUICC by writing to address ____, which causes
a QUICC interrupt on line INTL/.

The 80C323 accesses the DPR via its address and data busses using signals DPRCS/,

(N05). This HSD filter circuit output can be monitored at TP8.
6.5.68:1 MUX
Multiplexer circuit U7 is used to select the applicable HSD to be passed on to Dual
Digital Potentiometer U8. The inputs to U7 are applied to N01 through N05 (Pins 4, 5, 6,
7 and 12). The selection of HSD is made by the HS-FILTER_SEL inputs on U7, Pin 1
(A0), Pin 15 (A1) and Pin 15 (A2). EN (Enable) on Pin 2 is connected to +5V. The 8:1
MUX output COM is on U7, Pin 8.
6.5.7Dual Digital Pot
The output of the MUX circuit connects to the input of Addressable Dual Digital
Potentiometer U8, Pin 14 (HO). This device has two independently controlled
potentiometers. Only one pot is used in this application. The wiper can be set to one of
256 positions and is controlled by the microprocessor through the I2C data bus SCL (Pin
9) and SDA (Pin 10). The output on Pin 12 (WO) connects to the input of amplifier
circuit U6B.
6.5.8Inverting Buffer/Amplifier
Amplifier circuit U6B is an inverting buffer/amplifier with a gain of approximately 1.5.
The output of this circuit is connected to the input of analog switch U9. The output of
this circuit can be monitored at TP9.

Analog Switch U9 is a Single-Pole/Double Throw (SPDT) with one normally closed and
one normally open switch. Switching times are less than 175 ns max for tON and less
than 145 ns max for tOFF. Analog Switch U9 switches between RFTXDATA (U9, Pin 2
(S1)) coming from inverting Buffer/amplifier U6B and ANALOG AUDIO (U9, Pin 8
(S2)). S1, Pin 2 (RFTXDATA) is the normally closed contacts. The output is on U9, Pin
1 (D) MOD. This device is controlled by MODCTL on U9, Pin 6 (IN). +5V connects to
U9, Pin 5, (VL). +12V connects through Diode D1 to U9, Pin 4 (+V) and –12V connects
through Diode D2 to U9, Pin 7 (-V).
6.5.8Clock Generation
Clock generation is accomplished by inverter circuits U32C and U32D and Dual 4-Stage
Binary Ripple Counter U3. U32C and 400 kHz crystal Y1 form a 400 kHz oscillator
circuit. The output of U32C connects to the input of U32D. The 400 kHz clock (CLK)
output of 32D connects to U3, Pin 1 (CP1). This 400 kHz CLK can be monitored at
TP10. Counter U3 divides the 400 kHz CLK down to produce a 25 kHz CLK. This
output can be monitored at TP11. The 400 kHz CLK is further divided down to produce
a 3.125 kHz CLK. This output can be monitored at TP12.

6.5.9Low Speed Data Decoder Filter
The Low Speed Data Decode Filter is used to remove voice-audio (300-3000 Hz) leaving
only the low-speed or subaudible data for an input to the microprocessor.
VOLSQ is coupled through capacitor C33 to the input of buffer/follower circuit U15A
6.5.10Low Speed Data Encode Filter
The Low Speed Data Encode filter is used to smooth out transitions of data impressed
upon the voice audio. Low-speed data is a 150 bit per second data stream generated by
the microcomputer and used to produce subaudible data on the voice audio.
Low-Speed Data is generated by microcomputer U9A through EPLD U27, Pins 81 and
80, Walsh Bit 1 and Walsh Bit 2 respectively. For low-speed data, the two Walsh bits are
scaled and summed through analog switch U22. The output of U22, Pin 1 (D) connects
through operational amplifier U19A and buffer/follower U19B to the input of the low-
speed-data encode filter U21. The output of U19B can be monitored at TP22. U21 is an
active filter, which uses resistors R82, R90 and R93 with an external 3.125 kHz CLK to
produce a low-pass filter. The output of U21 can be monitored at TP20. This output
connects to the input of low pass filter U20, Pin14 (IN). This filter

LIGHTNING PROTECTION GROUNDING
11.0LIGHTNING PROTECTION GROUNDING
Maximum lightning protection is achieved when the GETC Lingtning-Protection
Grounding Kit (344A4500) is installed. This kit is normally installed at the factory for all
trunking applications. The following procedure summarizes the installation process:
1. Two wires (black #16 AWG hookup wire, 2-feet long) are prepared as follows:
a. The wires are stripped and tinned ½-inch on one end and 1-inch on the other end.
b. A solderless terminal (19B209260P1), bent approximately 30-degrees so it will
clear the board mounting screw, is attached to the end stripped back ½-inch on
each wire as shown in Figure.
Figure 9 - Lightning-Protection Kit Installation Detail
2. The solderless terminal end of the wires is then attached to the SitePro Controller
Interconnect Board A1 using the lock washers and machine screw as shown in the
above Figure. A chinch nut is already mounted to the solder side of the board.
3. The wires are then routed out of the shelf as shown in Figure 4.
