Motorola MT2000 System Pretime, Preamble During Pretime, Inter-Packet Time, Limited Patience Time

CHANGE/VIEW MTSX RSS

FIELD DEFINITIONS:

MDC System

Use the UP/DOWN arrow keys to change the MDC system or directly enter the system number. Valid entries are 0 to 630ms in increments of 50ms.

System Pretime

This is the amount of pretime used before the first MDC packet is transmitted.

Preamble During Pretime

This is to enable preamble sequence transmission before voice transmissions.

Inter-Packet Time

The Inter-sequence pretime is the period of time between consecutive MDC messages. Valid entries are in the range 0 to 6350 ms in steps of 50 ms increments. Due to the rounding that occurs when preamble during pretime is enabled, the value shown may change by 50 ms when a codeplug is read from a radio or file. This is just in the Radio Service Software, not the radio.

Limited Patience Time

This is the amount of time that transmission of a polite MDC signal will wait before sending out an impolite signal. The range of values are 1-255 sec. and Infinite. The factory default is 60 seconds.

DOS (Data Squelch)

This enables the Data Operated Squelch feature. This keeps the radio from unmuting when data is being received.

Operation

When this field is disabled, only the 1800 Hz criteria for Data Operated Squelch is needed. When enabled, then both 1200 Hz and 1800 Hz signals are required for DOS. The factory default is 1200/1800 Hz.

Coast Time

This is the delay for which the audio will remain muted after the received MDC message is finished. Valid entries are from 0 to 1134.75 in 4.45 ms increments.

Sel Call Reset

This determines how the Select Call mode is reset after receiving a Select Call and the radio has unmuted. The radio will return from carrier squelch mode to select call packet required mode according to this field.

Auto resets the radio after the Sel Call Auto Reset timer has expired.

Auto w/carrier override resets the radio waits until the voice stops.

Both modes can be reset manually by pressing the monitor button.

Auto Reset Time

This is the time the radio will remain in carrier squelch mode after the radio has received a select call directed to it. Once the auto reset time has expired, the radio will reset to the Select Call squelch mode. The valid range of values are 1 to 255seconds. The factory default is 60 seconds.

Emergency Limited Patience Time

When the radio is in Emergency Call Mode, this is the amount of time (in seconds) the radio will wait before impolitely sending voice if voice transmission is inhibited by the Emergency Priority Inhibit feature. The valid range of values are 1 to 255seconds. The factory default is 5 seconds.
