Automatic Sample Window Setup
These commands are used to configure the Sample Window timer, which control
how long the patch remains in receive looking for carrier when it samples.
Command 78# can only be done from the radio. Once the command is entered,
the Model 30 keys up for two seconds. While it is keyed, the technician keys up
and sends a continuous DTMF digit. When it unkeys, the Model 30 times how
long it takes after dropping PTT before a valid DTMF digit is decoded. It saves
this time as the Sample Window time. This test should be run only after
installation and all level adjustments are complete. Commands 79# and 80#
allow the technician to adjust the size of the window manually if operating
experience indicates the need.

Decrement Sample Window by 10 ms
COR Hold Time
This timer is similar in function to the VOX Hold timer. It sets the amount of
time that carrier detection must go away before the patch reacts to it and switches
from receive back to transmit. Valid entries are 0 to 5, in 100 millisecond
increments, giving a range of 0 to 500 milliseconds.
81#
___#
Set COR Hold Time ( range is 0 to 5)

Busy Tone Detector
The Model 30 uses its VOX detector to look for the characteristic pattern of busy
tone during the first 20 seconds of any mobile originated phone call. If it detects
a busy tone it disconnects the call automatically. This is particularly useful on
simplex systems. A disable is provided for this feature because some automated
telephone voice prompts can be falsely identified as busy tone. This feature can
also be set to be active for the entire call.
85#
___#
Set Busy Tone Detect Mode
0 = Busy Tone Detection Disabled
1 = Disconnect If Busy Detected in First 20
Seconds
2 = Disconnect If Busy Detected During Entire
Call
