Version 4.4 103 March 2005
Table 5-28: Protocol Definition, ini File Parameters (continues on pages 102 to 103)
Parameter Description
PolarityReversalType
Defines the voltage change slope during polarity reversal or wink.
0 = Soft (default).
1 = Hard.
Note 1: Some Caller ID signals use reversal polarity and/or wink signals. In these cases
it is recommended to set PolarityReversalType to 1 (Hard).
Note 2: Applicable only to FXS gateways.
CurrentDisconnectDuratio
n
Duration of the current disconnect pulse (in msec).
The default is 900 msec, The range is 200 to 1500 msec.
Applicable for both FXS and FXO gateways.
Note: The FXO gateways’ detection range is +/-200 msec of the parameter’s value +
100.
For example if CurrentDisconnectDuration = 200, the detection range is 100 to 500
msec.
CurrentDisconnectDefault
Threshold
Determines the line voltage threshold which, when reached, is considered a current
disconnect detection.
Note: Applicable only to MP-10x/FXO gateways.
The valid range is 0 to 20 Volts. The default value is 4 Volts.
TimeToSampleAnalogLine
Voltage
Determines the frequency at which the analog line voltage is sampled (after offhook), for
detection of the current disconnect threshold.
Note: Applicable only to MP-10x/FXO gateways.
The valid range is 100 to 2500 msec. The default value is 1000 msec.
AnalogCallerIDTimimgMo
de
0 = Caller ID is generated between the first two rings (default).
1 = The gateway attempts to find an optimized timing to generate the Caller ID according
to the selected Caller ID type. Note that when used with distinctive ringing, the Caller ID
signal doesn’t change the distinctive ringing timing.
Note: Applicable only to FXS gateways.
