Cisco IE-3000-8TC Administration Guide

DescriptionSettings
If enabled, the SPA8800 disconnects both call legs when the VoIP
side (non-PSTN) has no voice activity for a duration longer than the
length specified in the VoIP Long Silence Duration parameter during
a call across the connection.
Detect VoIP Long Silence
This field defines the minimum length of PSTN silence (or inactivity)
in seconds to trigger a disconnect of a call across the SPA8800 device
if Detect PSTN Long Silence is enabled.
PSTN Long Silence Duration
This field defines the minimum length of VoIP silence (or inactivity)
in seconds to trigger a disconnect of a call across the SPA8800 device
if Detect VoIP Long Silence is enabled.
VoIP Long Silence Duration
This parameter adjusts the sensitivity of PSTN silence detection.
Choose from {very low, low, medium, high, very high}. The higher
the setting, the easier it is to detect silence and trigger a
disconnection.
PSTN Silence Threshold
This field defines the minimum duration, in seconds, of a low
tip-and-ring voltage for the SPA8800 device to recognize the drop
in voltage as a CPC signal or PSTN line removal.
Min CPC Duration
If enabled, the SPA8800 device disconnects both call legs when it
detects the disconnect tone from the PSTN side during a call across
the device. The disconnect tone varies by country and can be affected
by the country of deployment chosen during First Time Setup (FTS).

This field defines the input gain for the FXS port in dB, up to three
decimal places. The range is 6.000 to -12.000.
FXS Port Input Gain
This field defines the FXS output gain in dB, up to three decimal
places. The range is 6.000 to -12.000. The Call Progress Tones and
DTMF playback level are not affected by the FXS Port Output Gain
parameter.
FXS Port Output Gain
This field defines the local DTMF playback level in dBm, up to one
decimal place.
DTMF Playback Level
This field defines the local DTMF playback duration in milliseconds.DTMF Playback Length
This field sets the electrical impedance of the FXS port. Choices are:
600, 900, 600+2.16uF, 900+2.16uF, 270+750||150nF,
220+850||120nF, 220+820||115nF, or 200+600||100nF.
