MTC-3600™ Controller is the central call processing equipment that uses advanced PowerPC processing with CompactPCI technology. It provides trunked operation in Single Site Trunked Radio Systems or Motorola Simulcast Trunked Systems. When combined with other equipment, the MTC-3600 Controllers yield leading edge trunked radio operation, system management and control. In addition to supporting features like Selective Calls, Group Calls and Push to Talk ID Display, key features and benefits yielded by the controller are listed below.
The MTC-3600™ combined with ASTRO™ equipment yields leading edge trunked radio operation, system management, and control. With SmartNet ASTRO Secure, transmissions can be protected from unauthorized monitoring with digital encryption methods.
MTC-3600™ has been developed to support the continuing life of 3600-baud control channel systems. The MTC-3600 is a functional replacement of the MC-6809-based SmartNet Central Controller.
The MTC-3600 supports all three modes of operation (that is, analog, ASTRO and mixed mode). SmartNetII++ uses Motorola's proprietary ASTRO technology for digital operation. For digital communications, the MTC-3600 interfaces with a Data Broadcast Box (DBB), which forwards control information between the MTC-3600 and the ASTRO-capable base stations. The base stations extract and embed control information in the digitized audio signal.
For dispatch calls, the Central Electronics Bank (CEB) sends console audio to the Digital Interface Unit (DIU). The DIU digitizes the voice signal and sends the signal to the base station for transmission. The DIU also converts inbound digital audio to analog. SmartNetII trunked radio systems can operate in analog, ASTRO or mixed modes. The DIU also interfaces three-wire audio to Balanced/Unbalanced Converter, converting to four-wire audio that in turn interfaces to the Central Interconnect Terminal (CIT).
The MTC-3600 trunking controller provides site control for standalone SmartNetII++ systems and replaces Motorola's MC-6809 processor-based site controller. The MTC-3600 has been designed to extend the reliable MC-6809 controller functionality into the future and to be a drop-in replacement for legacy MC-6809 systems.
Primary site control operations occur on the MTC-3600 system board (MCP-75O). Many supporting operations that were performed by peripheral MC-6809 controller cards (e.g., Receiver Site Controller, Transmitter Site Controller, etc.) have been consolidated into the MTC-3600's ACE-1 (Analog/digital Communications Engine) board.
Since the MTC-3600 was designed as an emulator of the MC-6809, system and diagnostic messages still refer to the appropriate peripheral MC-6809 components, which are now functions rather than actual MC-6809 components.
The MTC-3600 in a stand-alone SmartNetII++ system contains the components shown in the overhead. These components are housed in a Motorola CPX-2408 CompactPCI chassis that includes a 400-watt power supply. (Dual 400-watt power supplies are an option.) The MTC-3600 has eight card slots, one system slot and seven peripheral slots. Processing boards are located in the front bay, attached to the backplane. Each processing board has a corresponding transition card installed on the other side of the backplane, which provides I/O ports. Refer to the table on the following page for a brief description of these component boards.
In the MTC-3600, the processing boards (the system board and the ACE boards) are located in the front of the chassis and plug into the mid-plane. The transition cards (PAM and RIC cards) are located at the back of the chassis and plug into the other side of the back plane. The PAM (Port Asynchronous Module) board is a transition board for the MCP-75O system board and the system components controlled by the MTC-3600 central site controller.
The PAM (Port Asynchronous Module) board provides physical ports for the SMT, Alarms, CIT, and Redundant Controller Affiliation Link.
The RIC (Repeater Interface Card) card is a transition card, which provides connection ports between the MTC-3600 and base station repeaters, and serial links to the PAM board.

The MTC-3600 transition cards connect to other site devices through RJ connectors at the back of the transition boards.
The MTC-3600 connects to each base station repeater with one cable from one of the first seven RIC card connector ports. Any of the first seven connector ports can connect to a voice channel repeater. To serve as a control channel, at least one base station repeater must be connected to connector ports 1-4 on the RIC card opposite the ACE-1 board (slot 7).
If connector ports 1-4 all have connections to base station repeaters, the MTC-3600 uses one channel as a control channel and the other three channels as voice channels. The MTC-3600 can use any of the base station repeaters connected to connector ports 1-4 as the control channel. Control and voice channels use the same cables.
These links carry voice channel control signals, control channel data and repeater control/status signals.
For systems using a separate terminal or personal computer (PC) for the System Manager's Terminal (SMT), the MTC-3600 connects to this terminal with an RS- 232 cable from connector pout C on the PAM card to a serial pout on tl4terminal or personal computer. (The PAM card is opposite the MCP-75O system board in slot 8.) If using terminal emulation software, configure the connection through a COM port on the PC at 4800-baud, no parity, 8 data bits and 1 stop bit.
Another option is Site Lens - a PC-based network management product that includes "SMT Access" a terminal emulating software designed to interface to the MTC-3600.
For systems offering the Centralized Interconnect Terminal (CIT), the MTC-3600 connects to the CIT's MCB card with an RS-232 cable from connector port C on the PAM card. (The PAM card is opposite the MCP-75O system board in slot 8) The MTC-3600 sends CIT command over this connection, along with SMT data.
The MTC-3600 connects to an Alarm Indicator device with a cable from the Alarms Active/Idle connector port on the PAM card located in slot 8. This dry contact link conveys major and minor alarms to the Alarm Indicator device.
The MTC-3600 connects to the base stations using RJ-45 connectors on the RIC card
Connections between MTC-3600 boards occur over the following paths:
A local PCI bus within the MCP-75O and MCPN-75O boards allow for conversion of CompactPCI input to IEEE-1394 output and vice versa.
Communication between the MCP-75O system board and the ACE-1 board occurs over two physical RS-232 interfaces that use 8 conductor cables and RJ-45 connectors.
One interface, cabled between the PAM card's connector port-A and the RIC-1 card's connector port SER 1, support the TSC link between the MCP-75O and the ACE-1 boards.
The second interface, cabled between the PAM card's connector port-B and the RIC-1 card's connector port SER 2, support the RSC link between the MCP-75O and the ACE-1 boards.
The Transmitter Site Controller (TSC) and Receiver Site Controller (RSC) are functions that run on the Primary Site Asychronous Communications Engine (ACE-1) board.
For additional detail concerning the interconnection and relationship of the MCP-75O and ACE boards, see the MTC-3600 Installation and Configuration Booklet, 68P81000Y37, latest revision.
The ACE-1 board communicates with up to three Analog/digital Communications Engine (ACE) boards over the IEEE-1394 Serial Bus. This connection supports communications between the Receiver Interface Board (RIB) and Transmitter Interface Board (TIB) functions for the channels controlled by other ACE boards and the Transmitter Site Controller (TSC), Receiver Site Controller (RSC) and Inbound Recovery Board (IRB) functions that are on the ACE-1 board. ACE-2, ACE-3, and ACE-4 boards do not communicate directly with other MTC-3600 components.
For additional detail concerning the interconnection and relationship of the ACE boards, see the MTC-3600 Installation and Configuration Booklet, 68P81000Y37, latest revision.
The MTC-3600 uses CompactPCI single-board computers for site control, digital signal processing and peripheral controller options. Transition cards provide I/O access from the rear of the chassis. This section describes the following MTC-3600 component boards:
The MCP-75O system board hosts the controller software and performs the CSC (Central Site Controller) function. The MCP-75O connects to the backplane of the MTC-3600 chassis in the system slot (8), which is also labeled CPU. The system slot is responsible for system initialization, configuration, PCI bus arbitration and system interrupt and error handling.
The system board has a bootable, IDE Compact Flash Memory card, which emulates an IDE disk drive and stores the system code plug information and controller software. This memory card can be replaced in the field, if necessary. It is shipped from the factory fully configured with system information.
Four serial ports route to backplane connectors, accessible through the Port Asynchronous Module (PAM) card. The MCP-75O system board also possesses an Ethernet controller with a lO/lOOBaseT port located on the front panel. The Ethernet port is used for loading software updates and reconfiguration information. For more information on these processes, refer to the booklet, MTC-3600 Expansion Information.
The MCP-75O system board uses a Port Asynchronous Module (PAM) transition card. For more information about this card, refer to the section, PAM Card, later in this web page.

Important: Setting squelch too high or too low causes abnormal operation. For example, if you set squelch too high, you may not be able to access the system. If you set squelch too low, the controller may try to use random noise as data, resulting in error messages. Both cases will result in degraded system performance.
| Manual squelch setting: | |
|---|---|
| 1 | Wait for the ACE-1 board startup banner to appear and a control channel to be assigned. Then using the ACE Diagnostic Interface, press 'Enter'. Result: A logon prompt appears. |
| 2 | At the login prompt, type control and press 'Enter'. Result: The Enter Password prompt appears. |
| 3 | Type trunking and then press 'Enter'. Result: The "ACE>" prompt appears. |
| 4 | Type sqlh and then press 'Enter'. Result: The current squelch value appears, followed by the following prompt: Change (Y/N/+/..)? |
| 5 | Type Y and then press 'Enter'. Result: The Enter New Squelch Value prompt appears. |
| 6 | Set the squelch value by typing + to increment by one value. Continue typing + until you reach the value where the squelch LED is extinguished. You can type - to decrement by one value, if necessary. You can also enter a numerical value for the squelch setting by typing Y then pressing 'Enter' Result: The UNSQ LED flickers then extinguishes if the setting is connect. Once the value is set, it is maintained in nonvolatile memory. |
| 7 | Confirm the correct setting by using a radio to place a call. Result: The UNSQ LED illuminates briefly, then the DECD LED illuminates briefly. Finally the radio channel is assigned. |
| 8 | If you have two to four repeaters that can act as the control channel, disable the current control channel and repeat this procedure for all remaining control channels. Use the lowest squelch value to ensure proper operation across all control channel repeaters. |
Manually Enabling and Disabling Channels
The channels can be enabled and disabled to force the use of an single control channel and voice channel in order to test a certain channel for voice communications. Trunked systems will have 1-28 channels.
The following procedure will enable and disable channels using the E/D-SEL switch on the ACE boards.
NOTE: You cannot use the E/D-SEL switch to select un-configured channels or channels disabled by the System Manager Terminal (SMT) interface.
