Description between the Pre-driver stage and the Final Module. The gain of the Pre-driver stage is controlled by a power control voltage which is derived from power control signals (from the SCM) and high VSWR/thermal protection circuitry on the PA output board.
Description Receiver Circuitry Operation Introduction The Receiver Circuitry accepts receive rf signals from the site receive antenna, per- forms filtering and dual conversion, and outputs a digitized receive signal to the Sta- tion Control Module. The receiver module utilized may have either an internal varactor-tuned preselector filter, or an external metal preselector filter.
Description Station Control Module Operation Introduction The Station Control Module (SCM) is the microprocessor-based controller for the sta- tion. Major components include an MC68356 microprocessor, which combines a 68302 Integrated Multiprotocol Processor (IMP) with a 56002 Digital Signal Processor (DSP), a DSP ASIC device, and several Codec filter devices. Station Control Module Operation The MC68356 forms the heart of the SCM.
A latch receives control signals from the SCM (via the SPI bus) to control the gat- ing of the audio signals. For a list of the actual features supported, refer to the “Summary of Operating Fea- tures” on page 3, or the MTR2000 System Planner. Note 68P81096E36-H...
Description Auxiliary I/O Board Operation Introduction The Auxiliary I/O Board serves as the interface between the customer auxiliary equipment and the Station Control Module (SCM). In general, the Auxiliary I/O Board routes all auxiliary equipment control signals between the SCM and the aux- iliary equipment (e.g., a trunking controller).
Description Power Supply Module Operation Power Supply Modules are offered to handle: • ac or dc input power • low power (250 W) or high power (500 W) station requirements A high power Power Supply Module (500 W) is used in a station with a high power Power Amplifier Module (e.g., rated at 100 W or 75 W output power).

Installation Overview The following information is an overview for installing the station and an- cillary equipment.
Installation • Perform a post-installation functional checkout test of the equipment to verify proper installation • Proceed to the Optimization procedures to customize the station pa- rameters per customer specifications (e.g., operating frequency, PL, codes, etc.) Regulatory requirements may require the use of an optional high stability reference for some modes of operation.
The high-power (100/75W) stations are equipped with cooling fans that are used to provided forced convection cooling. When planning the installation, observe the following ventilation guide- lines: Mounting the MTR2000 • Customer-supplied cabinets must be equipped with ventilation slots in a Cabinet or openings in the front (for air entry) and back or side panels (for air to exit).
Beginning January 1, 2001, input harmonic current specifications were European Union (EU) changed for most electronic telecommunication equipment installed in EU countries. Accordingly, power factor correction is necessary for MTR2000 Countries stations. Power Supply models DLN6622 and DLN6624 have internal power factor correction.

The phone lines may carry analog voice, or encoded voice. Also carried on the phone lines are Tone Remote Control (type of remote control signalling).
Installation Telephone Line Specifications Most telephone companies recognize either “3002” or “Type 5” as desig- nations to define phone line types and associated electrical specifications. Telephone lines meeting the specifications for either of these types are ac- ceptable for use with the station. Table 9 shows the specifications for “3002”...
Installation Location of Telephone Line Connections Wireline Connector When 4-wire (2 line) telephone connections are required, Line 1 and Line 2 are provided through the 4–position wire wrap terminal connector. Table 10 provides a description of the Wireline connector line pair assign- ments.
Installation System Type vs. Wireline Circuit Table 11 shows which of the four (4) wireline circuits to use for various sys- tem types. Stations equipped with a 4–wire Wireline Interface can support a single 4– wire or a single 2–wire telephone line connection. Note Stations equipped with an 8–wire Wireline Interface can for example sup- port a two 4–wire or a single 2–wire telephone line connection.
Installation Station Maintenance Connections Table 12 provides a description of the maintenance connections located on the front of the Station Control Module. Table 12. Station Maintenance Connections on the SCM Connector Function Details Name 5/10MHz External 5MHz or 10MHz external External Reference signal reference may be used.
Installation POST INSTALLATION CHECKLIST After the station equipment has been mechanically installed and all electrical connections have been made, power may now be applied and the station checked for proper operation. Applying Power Before applying power to the station, make sure all boards are securely seated in the appropriate connectors on the backplane and that all rf cables are securely connected.
Installation Verifying Proper Operation Operation of the station can be verified by: • observing the state of the 4 LEDs located on the front panel • listening to audible alarms, and • exercising radio operation. Some station components can become extremely hot during station op- eration.
