Field Description
(PSTN) Long Silence This value is minimum length of PSTN silence (or inactivity) in seconds to
Duration trigger a gateway call disconnection if Detect Long Silence is yes.
The default is 30.
Silence Threshold This parameter adjusts the sensitivity of PSTN silence detection. Choose from
{very low, low, medium, high, very high}. The higher the setting, the easier to
detect silence and hence easier to trigger a disconnection.
The default is medium.
Disconnect Tone This value is the tone script which describes to the SPA the tone to detect as
a disconnect tone. The syntax follows a standard Tone Script with some
restrictions. Default value is standard US reorder (fast busy) tone, for 4
seconds.

Linksys ATA Administration Guide
2 frequency components must be given. If single frequency is desired,
the same frequency is used for both
The tone level value is not used. –30 (dBm) should be used for now.
Only 1 segment set is allowed
Total duration of the segment set is interpreted as the minimum
duration of the tone to trigger detection
6 segments of on/off time (seconds) can be specified. A 10% margin is
used to validated cadence characteristics of the tone.
