ini File Parameter Description
NTTDIDSignallingForm
Determines the type of Direct Inward Dialing (DID) signaling support for
NTT (Japan) modem: DTMF- or Frequency Shift Keying (FSK)-based
signaling. The devices can be connected to Japan's NTT PBX using
'Modem' DID lines. These DID lines are used to deliver a called number to
the PBX.
 [0] = FSK-based signaling (default)
 [1] = DTMF-based signaling
Note: This parameter is applicable only to FXS interfaces.
EnableDID
This ini file table parameter enables support for Japan NTT 'Modem' Direct
Inward Dialing (DID). FXS interfaces can be connected to Japan's NTT
PBX using 'Modem' DID lines. These DID lines are used to deliver a called
number to the PBX. The DID signal can be sent alone or combined with an
NTT Caller ID signal.
The format of this parameter is as follows:
[EnableDID]
FORMAT EnableDID_Index = EnableDID_IsEnable, EnableDID_Port,
EnableDID_Module;
[\EnableDID]
Where,
 IsEnable = Enables [1] or disables [0] (default) Japan NTT Modem DID
support.
 Port = Port number.
 Module = Module number.
For example:
[EnableDID]
EnableDID 0 = 1,2,0;
[\EnableDID]
Notes:
 This parameter is applicable only to FXS interfaces.
 For an explanation on using ini file table parameters, refer to ''Structure
of ini File Table Parameters'' on page 293.
EnableCallerIDTypeTw
o
Disables the generation of Caller ID type 2 when the phone is off-hooked.
Caller ID type 2, also known as off-hook Caller ID is sent to a currently
busy telephone to display the caller ID of the waiting call.
 [0] = Caller ID type 2 isn't played.
 [1] = Caller ID type 2 is played (default).
PolarityReversalType
Defines the voltage change slope during polarity reversal or wink.
 [0] = Soft reverse polarity (default).
 [1] = Hard reverse polarity.
Notes:
 This parameter is applicable only to FXS interfaces.
 Some Caller ID signals use reversal polarity and/or Wink signals. In
these cases, it is recommended to set PolarityReversalType to 1 (Hard).
