Parameter
[TimeBetweenDIDWinks] Defines the interval (in msec) for wink signaling:
Web/EMS: Delay Before
DID Wink
CLI: delay-b4-did-wink
[DelayBeforeDIDWink]
EMS: NTT DID Signalling
Form
CLI: NTT-DID-signaling-

[NTTDIDSignallingForm]
EMS: Enable DID
[EnableDID]
Version 6.8
an off-hook state. A polarity change from normal to reversed is
generated after a user-defined time (configured by the
TimeBetweenDIDWinks parameter). DTMF/MF digits are
collected by the device only after this polarity change. Digits that
arrive between the first Wink and the polarity change are ignored
as they always contain the same number. In this mode, the FXS
interface does not generate a polarity change to normal if the Tel-
to-IP call is answered by an IP party. Polarity reverts to normal
when the call is released. For example:
(Wink) KP 911 ST (Polarity) KP I(I) xxx-xxxx ST (Off Hook)

FXO: For IP-to-Tel calls:
1) Upon incoming INVITE message, the FXO interface goes off-
hook (seizes the line).
2) Upon detection of a Wink signal from the Tel side (instead of a
dial tone), the FXO interface dials the digits, "KP911ST" (denotes
*911#).
3) The FXO interface waits for polarity reversal change from
normal to reverse for an interval of 2,000 msec.
4) Upon detection of a polarity reversal change, the FXO
interface dials the DTMF (or MF) digits of the calling party
(number that dialed 911) in the format "KP<ANI>ST" (*ANI#),
where ANI is the calling number from the INVITE. If no polarity
reversal, the FXO goes idle.
For example: (Wink) KP911ST (Polarity Change) KP02963700ST
Note: The Enable911PSAP parameter must be set to 1.
Notes:

The EnableReversalPolarity and PolarityReversalType parameters
must be set to 1 for FXS interfaces.

This parameter can also be configured in a Tel Profile.

Double-wink signaling [2]: interval between the first and second wink

Wink and Polarity signaling [3]: interval between wink and polarity
change
The valid range is 100 to 2000. The default is 1000.
Note: See the EnableDIDWink parameter for configuring the wink
signaling type.
Defines the time interval (in msec) between the detection of the off-hook
and the generation of the DID Wink.
The valid range is 0 to 1,000. The default is 0.
Note: This parameter is applicable only to FXS interfaces.
Determines the type of 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] = (Default) FSK-based signaling

[1] = DTMF-based signaling
Note: This parameter is applicable only to FXS interfaces.
This table parameter enables support for Japan NTT 'Modem' 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
