Mediant 800B Gateway & E-SBC
Parameter Description
[R1DetectionStandard] Determines the MF-R1 protocol used for detection.
 [0] = ITU (default)
 [1] = R1.5
Note: For the parameter to take effect, a device reset is required.
user-defined-tones-detector-
enable
[UserDefinedToneDetectorEnable]
Enables the detection of User Defined Tones signaling,
applicable for Special Information Tone (SIT) detection.
 [0] = Disable (default)

[1]
= Enable
sit-detector-enable
[SITDetectorEnable]
Enables SIT detection according to the ITU-T recommendation
E.180/Q.35.
 [0] = Disable (default)
 [1] = Enable
To disconnect IP-to-ISDN calls when a SIT tone is detected, the
following parameters must be configured:
 SITDetectorEnable = 1
 UserDefinedToneDetectorEnable = 1
 ISDNDisconnectOnBusyTone = 1 (applicable for Busy,
Reorder and SIT tones)
Another parameter for handling the SIT tone is SITQ850Cause,
which determines the Q.850 cause value specified in the SIP
Reason header that is included in a 4xx response when a SIT
tone is detected on an IP-to-Tel call.
To disconnect IP-to-CAS or IP-to-FXO calls when a SIT tone is
detected, the following parameters must be configured:
 SITDetectorEnable = 1
 UserDefinedToneDetectorEnable = 1
 DisconnectOnBusyTone = 1 (applicable fo
r busy, reorder, and
SIT tones)
Note:
 For the parameter to take effect, a device reset is required.
 The IP-to-ISDN call is disconnected on detection of a SIT
tone only in call alert state. If the call is in connected state, the
SIT does not disconnect the call. Detection of busy or reorder
tones disconnect these calls also in call connected state.
 For IP-to-CAS calls, detection of busy, reorder, or SIT tones
disconnect the call in any call state.
udt-detector-frequency-deviation
[UDTDetectorFrequencyDeviation]
Defines the deviation (in Hz) allowed for the detection of each
signal frequency.
The valid range is 1 to 50. The default is 50.
Note: For the parameter to take effect, a device reset is required.
cpt-detector-frequency-deviation
[CPTDetectorFrequencyDeviation]
Defines the deviation (in Hz) allowed for the detection of each
CPT signal frequency.
The valid range is 1 to 30. The default is 10.
Note: For the parameter to take effect, a device reset is required.
