Guard Tone Frequency
The TSAM supports a wide range of tone frequencies. Valid frequencies range from 0 Hz to 5000 Hz. 0
Hz results in no Guard Tone being sent. Normal tones range from 300 Hz to 2500 Hz. The default Guard
Tone is 2175 Hz.
Guard Tone Level
HLGT is normally set to 0 dB referenced to maximum line level. A tone setting of -10 db0 is also
selectable. This setting is useful for solving phone line cross talk or compatibility issues.
Guard Tone Duration
The duration of the High Level Guard Tone (HLGT) is typically between 60 and 120 msec. The range of
allowable values is 0 to 32,767 msec. By selecting a longer time, immunity to false detection is increased
at the expense of increased system access time. A value of 0 results in no HLGT being sent, but Low
Level Guard Tone (LLGT) is still sent. See your base station specifications for minimum HLGT length.
