Glossary of Terms Term Definition ALCAutomatic Level Control: a circuit in the transmit RF path that controls RF power amplifier output, provides leveling over frequency and voltage, and protects against high VSWR (voltage standing wave ratio). ASFIC Audio Signalling Filter Integrated Circuit BKCBad Key Chirp CD Compact Disk CMPCompression CPS Customer Programming Software CSQCarrier Squelch DTMF Dual-Tone Multifrequency DPLDigital Private-Line™ EEPROM Electronically Erasable/Programmable Read-Only Memory: used by the radio to store its personality FirmwareSoftware, or a software/hardware combination of computer programs and data, with a fixed logic configuration stores in a read-only memory. Information cannot be altered or reprogrammed. FGU Frequency Generation Unit GaAsGallium Arsenide: a type of crystalline material used in some semiconductors. GKC Good Key Chirp ISWInbound Signalling Word: data transmitted on the control channel from a sub- scriber unit to the central control unit. LH DATA Longhorn Data: a bidirectional 0-5V, RS-232 line protocol that uses the micro- controller’s integrated RS-232 asynchronous serial communications interface (SCI) peripheral. LLELow Level Expander: slight amount of volume expansion; used to improve the signal to noise ratio. MCU Micro Controller Unit MRTIMotorola Radio-Telephone Interconnect: a system that provides a repeater con- nection to the Public Switched Telephone Network (PSTN). The MRTI allows the radio to access the telephone network when the proper access code is received. OMPAC Over-Molded Pad-Array Carrier: a Motorola custom package, distinguished by the presence of solder balls on the bottom pads. PC Board Printed Circuit Board PL Private-Line® tone squelch: a continuous sub-audible tone that is transmitted along with the carrier.
July, 20046881096C24-A G-2 PLLPhase-Locked Loop: a circuit in which an oscillator is kept in phase with a refer- ence, usually after passing through a frequency divider. PTT Push-To-Talk: the switch located on the left side of the radio; when pressed, causes the radio to transmit. RAMRandom Access Memory: the radio’s RAM is loaded with a copy of the EEPROM data. Registers Short-term data-storage circuits within the microcontroller. RESETReset line: an input to the microcontroller that restarts execution. RF PA Radio Frequency Power Amplifier RIBRadio Interface Box ROM Read Only Memory RSSIReceived Signal-Strength Indicator: a dc voltage proportional to the received RF signal strength. RPT/TA Repeater/Talk-Around SoftpotA computer-adjustable electronic attenuator Software Computer programs, procedures, rules, documentation, and data pertaining to the operation of a system. SPI (clock and data lines)Serial Peripheral Interface: how the microcontroller communicates to modules and ICs through the CLOCK and DATA lines. Squelch Muting of audio circuits when received signal levels fall below a pre-determined value. Standby ModeAn operating mode whereby the radio is muted but still continues to receive data TOT Time-Out Timer: a timer that limits the length of a transmission. TPLTone Private-line µC Microcontroller UHFUltra High Frequency µP Microprocessor VCOVoltage-Controlled Oscillator: an oscillator whereby the frequency of oscillation can be varied by changing a control voltage. VCOBIC Voltage-Controlled Oscillator Buffer Integrated Circuit VHFVery High Frequency VSWR Voltage Standing Wave RatioTerm Definition
