Production versions of this shelf consist of the following components: • Shelf Assembly Chassis MA101080V1 MA101080V2 • Interconnect Board Assembly (A1) CB101073V1 • Controller board Assembly (A2) CD101069V1 • Modem Daughter Board (A8) CB101074V1 • Rockwell Modem Interface Card Assembly (A3) Rockwell Modem Assembly (A7) ROA 117 2247 RYTUZ 921 01/1 • Analog Board (A4) CB101070V1 • Power Supply Module (A5) CONDOR DP1719 • Display Module (A6) Display Board Assembly (A6-A1) Cable (A6-W1) MA101082V1 CB101077V1 CA101222V1 • Input Cable to the Power Supply (W1) CA101211V1 • Output Cable from the Power Supply (W2) CA101212V1 • Data Cable (W#) CA101213V1 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. The 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. 10 MM101271V1 R1A • SCAT – The SitePro Controller can be programmed to provide command and control of a Single Channel Autonomous Trunking (SCAT) Site. • CNI – Programmed as a Conventional Network Interface (CNI), the SitePro Controller provides the communication link between a conventional communications site (analog) and an EDACS trunking system (digital). • Satellite Receiver – The SitePro Controller can be programmed to provide command and control of Satellite (Auxiliary) Receivers and communication to the Voter Digital Receiver. • Voter Digital Receiver – The SitePro Controller can be programmed to process digital data from Satellite Receiver SitePro Controller(s) for input to the Voter Selector. • Voter Selector – The SitePro Controller can be programmed to control the voting processes and select the sites with the best signals. • VDI – Programmed as a Voter Digital Interface, the SitePro Controller provides a path for Voter and Simulcast systems to the Jessica PBX system when making digital calls. • Simulcast Control Point and Tx Site – The SitePro Controller can be programmed to provide Simulcast system command and control.3 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) or two Rockwell 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. 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, the SitePro 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 supports EDACS and Simulcast. The analog and digital control signals provide an interface to a variety of base stations and are grouped by functionality. 4.4.1 Station Control • LocRxAudio - Analog input MASTR III level = 1 Vrms, Zin = 100Kohm, bias = ac coupled MASTR IIe level = .750 Vrms This signal is unfiltered local receiver audio from the base station also called Volume/Squelch or VolSq and carries either High Speed Data (control signaling/digital audio) or Low Speed Data with analog audio. The two components are internally separated. • RUS - Digital TTL active high input This signal is the Receiver UnSquelch signal from the base station and is activated when a carrier of sufficient signal strength (as determined by the squelch pot setting) is present. • LSD - Analog output level = 775 mVrms, Zout = 100ohm, bias = 0 volts 12 MM101271V1 R1A This signal is the Low Speed Data output to the base station. The signal is conditioned through a low pass filter to remove frequency components above 300 Hz to allow multiplexing with analog voice audio. • HSD - Analog output level = 775 mVrms, Zout = 100ohm, bias = 0 volts This signal is the High Speed Data output to the base station modulator. The signal is conditioned through a specially designed filter needed to meet precise RF modulation bandwidth limitations. • LocPTT - Digital active low open collector output This signal is the Local PTT control. This line, when low, will key up the base station transmitter and select the local receiver audio source for transmission. • RemPTT - Digital active low open collector output This signal is the Remote PTT control. This line, when low, will key up the base station transmitter and select the remote audio source for transmission. • A/DmodCtrl - Digital output TTL This is the Analog/Digital Modulation Control signal. When high, HSD is routed to the base station transmit. When low, LSD/audio is routed to the base station transmit. • HSAcq - Digital output open collector output This is the High Speed Acquisition control signal. A high or low signal produces a corresponding high or low time constant in the limiter circuit. • LocRxMute - Digital active low output (8.5 volt low Z source) This signal is the Local Receiver Mute control. This line, when low, blocks the routing of receiver audio to the base station transmitter and line out. Muting occurs during HSD transmission, no valid carrier present, or no valid LSD present. • Walsh1/Walsh2 - Digital output TTL These two signals are combined to form a two bit Walsh Function DAC. This signal is the Low Speed Data source. • Synth_Clk – Digital open collector output This signal provides the clock source for loading the base station frequency synthesizer (required for MIIe). Data is clocked on the negative edge of the clock. The baud rate is approximately 2.4Kbaud. • Synth_Data – Digital open collector output This signal provides the data source for loading the base station frequency synthesizer (required for MIIe). Data is clocked on the negative edge of the clock. The baud rate is approximately 2.4Kbaud. • Synth_LdEn – Digital open collector output This signal is the Synthesizer Load Enable control. This line, when high, permits the base station frequency synthesizer to be loaded and is used for protection against invalid transitions on the clock and data lines. • MM101271V1 R1A Synth_Locked – Digital TTL active high input 13 This is the Synthesizer Locked signal. This line, when high, indicates that the base station synthesizer is locked. This is used for verifying successful synthesizer loading and is also continuously monitored as a failure mode. • PAFail - Digital TTL active high input diode isolated with pullup This is the Power Amp Failure indicator. This line, when high, indicates that the base station PA has failed. A floating line asserts PA Fail. • RemAudioFlag - Digital TTL active low input, diode isolated This is the Remote Audio Present indicator. This line, when low, indicates that remote audio from the IMC is present. This is generated by the base station in response to 2175Hz or E&M from the IMC. • FSL - Digital open drain bi-directional output: 100 mA sink (low), 10mA source (high) input: Zin = 1Kohm This is the bi-directional Frame Sync Line. The line is used as an output in the Control Channel and as an input in the Working Channel. • ADCin – Analog input level = 0 to 5 volts, Zin = 100Kohm This is the 8-bit Analog to Digital Converter (ADC) input. This may be used to monitor station PA power. 4.4.2 Simulcast Control • ext_PTT - Digital TTL active low input, diode isolated This is the external source for Local PTT and is only active in a Simulcast configuration. • ext_A/Dmodctrl - Digital TTL active low input, diode isolated This is the external source for the Analog/Digital modulation control and is only active in a Simulcast configuration. • ext_150 - Digital TTL active low input, diode isolated This is the external source for Low Speed Data and is only active in a Simulcast configuration. • ext_9600baud - Digital TTL active low input, diode isolated This is the external source for High Speed Data and is only active in a Simulcast configuration. • bypass - Digital TTL active low input, diode isolated This is the Simulcast bypass control signal. This line, when low, forces the site to operate in non-Simulcast mode and is driven by the Simulcast control equipment. • inhibit - Digital TTL active low input, diode isolated This signal is the Simulcast alarm indicator. This line, when low, indicates the presence of a Simulcast alarm and is driven by the Simulcast control equipment. • 14 txclk_in - Digital TTL active low input, diode isolated MM101271V1 R1A This is the external source for High Speed Clock and is only active in a Simulcast configuration. • txclk_alarm - Digital TTL active high output This signal is the Simulcast Tx Clock alarm indicator. This line, when high, indicates that the external source for High Speed Clock is missing and is only active in a Simulcast configuration. 4.4.3 Conventional Control • CPTT – Digital open collector output This signal is the Combined PTT control. This line, when low, will key up the base station transmitter. • TxCGDis – Digital open collector output This signal is the Transmit Channel Guard Disable control. This line, when low, prevents the transmission of Channel. • CGMon - Digital TTL active low input, diode isolated This signal is the Channel Guard Monitor control. 4.4.4 Voter Control • vot_emsq - Digital open collector output This is the Voter E&M Squelch signal.

An internal switching DC-DC converter will be used to supply +/12 and +5volts to the SitePro Controller sub-components. • GND – power supply input This signal is the ground connection for the SitePro Controller. MM101271V1 R1A 17 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. It is 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. 5.4INTERFACE CONNECTIONS Table 3 - Interface Connections Connector J1 J2 J3 J4 J5 J6 J7 J8 J9 J10 J11 20 Interface Connections 32 Pin connector interfaces with Controller Board CB101069V1. 32 Pin connector interfaces with Analog Board CB101070V1. 32 Pin connector interfaces with Rockwell Modem Interface Card ROA 117 2247. 2 over 2 BSL/RM (Rockwell Modem).

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. 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.

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.

Pi filters U1 thru U29 eliminate any Electro Mechanical Interference (EMI). 6.3CONTROLLER BOARD (A2) Controller Board CB101069V1 contains all SitePro Controller logic and control functions except the power supply and Rockwell Modem (Refer to the Outline and Schematic Diagrams for the Controller Board as listed in the TABLE OF CONTENTS). This Controller Board is based on an MPC860 microprocessor, the primary responsibility being message processing. This board has multiple high-speed serial ports, two of which are used for primary and secondary BSL’s. It has hardware and dual port RAM to support the Modem Board and a 10/100 Mbit ethernet port. This port is available for Voice Over IP traffic. A second 10 Mbit ethernet port is available for management functions. This board has sufficient memory to support 1M LID’s and 64k GID’s. It has LID and GID validation for all calls. 6.3.1Block Diagram Figure 3 – Controller Board Block Diagram shows the connection of major components from a high level viewpoint.

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 hotswapable. The 5V output from this circuit will also power the 3.3 Volt regulator, thus 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 CIRCUIT ANALYSISN 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 halfduplex 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) • LSDIN (U18D) • SYNTH-LOCK DET (U23D) • PAFAIL (U18E) • SIMULCAST-INHBIT (U23E) • FSLIN (U18F) • BYPASS (U23F) • EXTPTTIN (U22B) • 5.0V 5.0V BACKPLANE MICROPROCESSOR BAV99 Figure 4 - Input Circuits U18A thru F, U22B thru D and U23A thru F In Figure 5 the Schmitt Trigger provides a sharp, well-defined input to the microprocessor MM101271V1 R1A 33 CIRCUIT ANALYSISN 5.0V 5.0V MICROPROCESSOR BACKPLANE Figure 5 - Input Circuits U22A thru F, U29D and U32B The FSL output from the microprocessor to the backplane is accomplished through inverter circuit U33A and FET Q2 (BKP-FSL). The RX-MUTE output from the microprocessor to the backplane is accomplished through Inverter U33D and transistor circuit Q1 (BKP-RX_MUTE). The EMSQTOAV output from the micropressor to the backplaned is accomplished through InverterU35C and transistor circuit Q6 (BKP-EMSQTOAV). Other outputs from the microprocessor to the backplane are connected through identical circuits as shown in Figures 6 & 7. Figure 6 shows circuits using Schmitt Triggers U29B, C, E, F and U32A & C to provide sharp, well-defined outputs to the backplane.

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.

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. 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.

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) 6.5.1 • I/O Connector (J2) QUIC Connector (J1) The QUICC (J9) connector contains the microprocessor interface (Refer to the Modem Daughter Board Section). 38 MM101271V1 R1A 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 WDCB101069V1, 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 SCC Ethernet Signal MM101271V1 R1A SCC Pin Name PHY Signal TX TXD1 10TXD TENA RTS1 10TXEN 39 CIRCUIT ANALYSISN TCLK CLKx 10TXCLK CLSN CTS1 10COL RENA CD1 10CRS RX RXD1 10RXD TCLK CLKx 10RXCLK 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. 6.4.6I2C 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 8bit 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: Table 7 - I2C Bus Addresses Device Addresses LED’s 0x40 DIP Switch 0x46 EEPROM 0xA0 Digital Pot 0x50 ADC/DAC 0x9E 16-Bit Expander 0x4C Display 0x4A 6.4.7Memory The Memory circuits for the Controller Board are shown on Schematic Diagram WDCB101069V1, Sheets 15 & 16 and include: 40 MM101271V1 R1A CIRCUIT ANALYSIS • DRAM Circuits U2 & U7 6.9.1 • Flash Circuits U10 & U11 DRAM Two 128-Mbit, 16 bit wide synchronous DRAM Integrated Circuit modules U2 and U7 are organized in a 4M x 32 configuration. These two modules provide a minimum of 16 Mbytes of storage, upgradeable to 64 Mbytes. The following table shows the MPC860P bank addresses for the different DRAM memory sizes. Table 8 - DRAM Bank Memory Ranges Bank 64-Mbit (DRAM) 128-Mbit (2xDRAM) 256-Mbit (SDRAM) Bank 1 0x003FFFFF – 0x00000000 0x003FFFFF – 0x00000000 0x013FFFFF – 0x01000000 0x003FFFFF – 0x00000000 0x013FFFFF – 0x01000000 0x023FFFFF – 0x02000000 0x033FFFFF – 0x03000000 Bank 2 0x007FFFFF – 0x00400000 0x007FFFFF – 0x00400000 0x017FFFFF – 0x01400000 0x007FFFFF – 0x00400000 0x017FFFFF – 0x01400000 0x027FFFFF – 0x02400000 0x037FFFFF – 0x03400000 Bank 3 0x00BFFFFF – 0x00800000 0x00BFFFFF – 0x00800000 0x01BFFFFF – 0x01800000 0x00BFFFFF – 0x00800000 0x01BFFFFF – 0x01800000 0x02BFFFFF – 0x02800000 0x03BFFFFF – 0x03800000 Bank 4 0x00FFFFFF – 0x00C00000 0x00FFFFFF – 0x00C00000 0x01FFFFFF – 0x01C00000 0x00FFFFFF – 0x00C00000 0x01FFFFFF – 0x01C00000 0x02FFFFFF – 0x02C00000 0x03FFFFFF – 0x03C00000 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 WDCB101069V1, 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 WDCB101074V1, 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. 42 MM101271V1 R1A MM101271V1 R1A 3.3V QUICC IFC RFINT/ PLINT/ VDIINT/ QD0 - QD7 EA P3.0 P3.1 P3.2 P3.3 U1 QA0 - QA15 80C323 CODE-A16 14.746 MHz X1 QCODECS/ QRD/ QDPRCS/ QWR/ MODINT2NUC BSY/ CODECS/ DEL/ CEL/ R/W/L INTL/ BUSYL/ 14.756MHz 14.756MHz RESET2MOD RESETIN/ 0 P1.4 0 P1.6 RESET J1 U3 RESET PE.4 PE.5 P1.0 P1.1 P3.2 P3.3 P1.5 P1.7 P3.7 P3.6 ALE OEL OER CEL CER R/WL R/WR BUSYL/ BUSYR INTL/ SEML SEMR INTL# INTR INT/R RWINT/ PLINT/ A0 - A7 RD/ WR/ U7 3.3V A0 - A15 D0 - D7 A0 - A7 U10 RFMODCS/ DIR OE DIR 3.3V DIR DIR OE A15 A14 A13 RESET U5 A/D0-7 X1 11 MHz VDIMODCS/ PLMODCS/ RFMODCS/ DPRCS/ RD/ WR/ A0 - A15 3.3 V D0 D7 D0 - D7 U2 PSEN/ CODE SRAM 64k x 8 RESETIN/ A0 A14 RD/ WR/ A16 OE/ WE/ SC/ A0 - A15 OE/ A15 U4 SRAM 32k x 8 RD/ RFMODCS/ PLMODCS/ UDIMODCS/ DATADIR 43 CIRCUIT ANALYSIS A0 - A15 CODE-A16 RESET U11 VDI MODEM ADDRESS DECODER D0 - D7 PSEN/ RESET WR/_5 DATADIR U12 ADDER OE BUFFER (16) RD/_5 RESETS D0-D7 A0-A7 U13 DATA OE BUFFER (8) X1 ALE_5 U6 CONV WR/ RESET INT/R A/D0-7 VDICS_5 RD/ RD/ DFRCS/ WR/ PL MODEM RFCS_5 PLCS_5 PLMODCS/ VDIMODCS/ ALE 3.3V CODECS/ RFRXDAT RFTXDAT RFTXCLK RFRCVDAT RFRCVCLK A0 - A7 8-BIT LATCH M/S R/W/L CS/ U9 ALE RF RD/ WR/ MODEM RESIN INT/ X1 A/D0-7 ALE PSEN/ A0 - A12 OEL/ CEL/ R/WL/ RFCS.5 ALE5 RD5 WR5 RESET5 RFINT RESET A8 - A15 D0 - D7 DUAL PORT RAM INT0/ INT1/ INT3/ INT5/ RXD0 TXD0 RSD1 TXD1 INT0/ CIRCUIT ANALYSISN Figure 8 - Modem Daughter Board Block Diagram 44 MM101271V1 R1A 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. MM101271V1 R1A 45 CIRCUIT ANALYSISN Address decoder U5 generates the Chip Selects for the three modems and the Dual Port RAM using signals RD/, WR/, A13, A14, and A15. Table 9 - Memory Map MEMORY MAP Device Range Code RAM 0-FFFF Dual Port RAM Data RAM 0-1FFF 8000-FFFF RF Modem PL Modem VDI Modem 2000-2003 4000-4003 6000-6003 6.4 Size 64K Bytes 8K Bytes 32K Bytes 4 Bytes 4 Bytes 4 Bytes 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/. 46 MM101271V1 R1A CIRCUIT ANALYSIS The 80C323 accesses the DPR via its address and data busses using signals DPRCS/, RD/, WR/, and INTl/. The QUICC accesses the DPR via its address and data busses using corresponding signals CEL/, R/WL/, OEL/, and INTL/. 6.7 Troubleshooting Aids Several signals are available on diagnostic connector J3 for troubleshooting purposes. Also probe points are provided for GND, 5V, and 3.3V.

Three address pins A0 (Pin 5), A1 (Pin 6) and A2 (Pin 7) can be used for programming a hardware address, allowing the use of up to eight devices to be connected to the I2C-bus without additional hardware. In this application, these three leads are tied to +5V. Address, control and data to and from the device are transferred serially through the two-line bidirectional I2C-Bus.

The frequency response of the HSD filter section is changed by selecting the output of only one filter circuit by 8:1 MUX U7. High-speed data is a 4800 or 9600 bit per second data stream generated by the microcomputer through the RF data modem U9 on the Modem Daughter Board. Each of the HSD filter circuits has two sections. 6.5.4.1 9600 Baud Wide Band This HSD filter circuit consists of operational amplifier U5B followed by operational amplifier U5A.

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).

Switching times are less than 175 ns max for tON and less than 145 ns max for tOFF.

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. 52 MM101271V1 R1A CIRCUIT ANALYSIS 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 lowspeed-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 6.6POWER SUPPLY (A5) MM101271V1 R1A 53 CIRCUIT ANALYSIS 6.7MISCELLANEOUS INFORMATION 6.7.1Serial Port Data Format The serial ports transfer RS-232 asynchronous serial data at a rate of 19.2k using the half-duplex operating mode.

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.

Controller Board Analog Board Rockwell Modem Interface Card Rockwell Modem Assembly Modem Daughter Board Power Supply Figure 10 - Lightning-Protection Kit Cabinet Installation 4. When the shelf is installed in the rack, use the split bolts to attach the wire ends stripped 1-inch to the cabinet earth-ground bus wire (part of the Cabinet grounding Strap Kit 344A4730) as shown in the split bolt side view in Figure 3. In order to be effective, the Cabinet Grounding Strap must be strapped to the building and/or earth ground.
