MDC Timers
DOS Coast Timer
The data-operated squelch is used to mute receive audio after the receipt of MDC data. This parameter
controls the length of time the speaker remains muted after a MDC1200 receive. The valid range for this
parameter is
0–2000 ms in 10 ms increments.
Emergency Ignore Time
This is the time that the unit will ignore subsequent emergency decodes from the same unit. Upon
successful decode of an emergency from a particular subscriber, a timer is set to the emergency ignore
time. Until this timer expires or the emergency is cleared by the operator, subsequent decodes from the
same unit are ignored and not acknowledged. The valid range for this parameter is
0 to 240 seconds .
Limited Patience Timer
The limited patience timer is used when a call type and target ID has been selected and the
TRANSMIT
button is pressed in the presence of receive audio activity. If this occurs, the desk set waits the limited
patience time for the receive activity to cease. If the activity remains, the unit transmits the data after the
timer expires.
However, if the activity ceases during the limited patience time, the data may be transmitted immediately
if the busy timer is not enabled. If this time is set to
0 , then there is no check for receive audio activity at
the beginning of the transmission and the busy timer is not used. The valid range of this parameter is 0-
240 seconds .
Retry Constant
This parameter allows you to select the time constant, M, used in the following formula:
T
WAIT
= 2 s (M + R)Pms
Where P is 10, R is a pseudo random number, and M is a constant value programmed. Increasing this
constant will result in an increased maximum wait time between retries. The valid range for this
parameter is
0 to 20 seconds
