SXMF5H PROGRAMMING, 12.5 KHZ CHANNEL, Factory configured station for narrowband operation (UHF/VHF Conventional FM Voice Only).
MM102558V1 R1A 5 OPERATION The MASTR III ADC station is a RF synthesized computer programmable, Frequency Modulated (FM) transceiver capable of wideband (25 kHz) or narrowband (12.5 kHz) operation. The MASTR III ADC station combines modular design and state-of-the-art technology to deliver superior performance and reliability. MASTR III ADC station incorporates fully shielded and removable modules, front-mount controls, and remote diagnostics.
MM102558V1 R1A DTMF tones are sent to the station via the wire line interface where the System Module decodes the tones as channel assignment information. The DC or Tone Remote signaling then controls the TX/RX operations of the station on the channel selected by the DTMF signaling. 5.1.2 Conventional Repeater When configured as a Conventional Repeater, the MASTR III ADC station provides full duplex (different TX and RX frequencies operating simultaneously) operation as a single channel repeater station.
MM102558V1 R1A 5.2.2 RF-Only Encryption/Decryption In RF-Only Encryption/Decryption (E/D) stations, external encryption equipment is connected directly to the MASTR III ADC station. The voice signal is always delivered clear (unencrypted) from the dispatch center to the base station where it can then be encrypted and sent over the radio path to properly equipped mobiles and portables. One or more station consoles operate in a standard clear mode, tone control configuration.
MM102558V1 R1A 5.3.3.1 Voice Guard Voice Guard is the first generation digital voice format available only as an encrypted signal. Voice Guard signals use Gaussian Minimum Shift Keying (GMSK), running at 9600 bps, two level FM modulation, Non-Return-to-Zero (NRZ), serial data. This means that the data is a serial train of two-state data bits (i.e., ones and zeros) occurring at the rate of 9600 bits per second.
MM102558V1 R1A 5.4.3 Advanced Encryption Standard Advanced Encryption Standard (AES) is a block cipher format approved for use as an encryption standard by the U.S. government. AES is fast in both software and hardware, is relatively easy to implement, and requires little memory. AES is currently used in conjunction with the P25 technology. Unlike DES, AES operates as a substitution-permutation network. AES utilizes fixed blocks of data formed into tables.
MM102558V1 R1A 5.5.2 P25 Conventional Repeater Station Operation In the P25 Repeater mode, the DSP Module uses the Delay PTT In line and the Remote PTT to communicate with the System Module. After the DSP Module demodulates a four-level FM signal, it asserts a Delay PTT In signal to the System Module, indicating a P25 call is being received.

MM102558V1 R1A 5.6 PROGRAMMABLE FEATURES FOR CONVENTIONAL STATIONS Most MASTR III ADC station features may be accessed using a PC compatible computer and the latest version TQS3353 Programming Software. Station configurations discussed in Section 5 require features to be properly set via programming software. Most MASTR III ADC feature programming is stored in the Station’s System Module.
MM102558V1 R1A 5.6.1 Conventional Stations (Setup) The initial Setup screen in the TQS3353 software allows the station to be defined as one of several Conventional station types include: No Remote, DC Remote, Tone Remote, Type 90 and DTMF. Other station types appear in the Setup screen however only the above are applicable to Conventional stations. The other station types are: Simulcast, Trunked and Multi-Receiver. 5.6.1.
MM102558V1 R1A The main programmable station data parameters include Transmit and Receive frequency, Channel Guard, TX Pot settings, CG Pot settings, RF Simplex/Rpt and PA Power settings. The following sections include a brief description of each parameter. 5.6.2.1 Transmit and Receive Frequency The System Module is programmed with most of the station’s features including transmit and receive frequency assignment.
MM102558V1 R1A 5.6.2.2.2 Digital Channel Guard The System Module also encodes and decodes Digital Channel Guard (DCG) tones. There are 83 digital codes available. Any of the digital codes can be assigned to any transmit or receive channel. DCG functions much like CG however provides many more user codes. The encoding function provides continuous, repetitive digital word modulation to the transmitter.
MM102558V1 R1A 5.6.6 Squelch Tail Elimination Squelch Tail Elimination (STE) eliminates the burst of squelch noise heard when the received carrier drops immediately and the CG circuit is still un-muted. When using STE, the transmitter remains keyed for a short duration when the PTT is released. When STE is enabled during CG tone signaling, STE directs the CG tone to be phase shifted by 135degrees.
MM102558V1 R1A For Battery Alarm tones to be passed down the wire line, it may be necessary to install R112 on the System Module. Refer to the System Module schematic for installation instructions. 5.6.8.3 Logic Standby When enabled, Logic Standby will restore certain station features in the event of a power failure or station reset.
MM102558V1 R1A 5.6.9.1 Two-Wire/Four-Wire Operation Two-wire describes a single pair of dedicated metallic wires in the form of discrete 600 ohm telephone wire provided by a customer, 600 ohm dry (quiet line only) telephone line provided by a telephone company, or the multiplexed equivalent provided by customer or telephone company owned equipment. This type of circuit will support the bi-directional transmission of audio signals in the nominal 300 to 3000 Hz frequency range.
MM102558V1 R1A 5.6.9.3 Tone Remote In tone remote applications, the T/R Shelf uses the System Module and its onboard Digital Signal Processor (DSP) to interface with a Tone Remote control unit through a two-wire or four-wire phone line.

MM102558V1 R1A 5.6.13 System Module - Digital Signal Processing The System Module also employs a State-of-the-Art audio Digital Signal Processing (DSP). Audio DSP is used to improve audio clarity, provide consistent audio leveling and enhanced tone generation and decoding for more flexible and reliable control functions.
