User's Manual 67. Configuration Parameters Reference
Version 6.8 931 Mediant 500L MSBR
Parameter Description
For example: (Wink) KP I(I) xxx-xxxx ST (Off Hook)
Where:

I = one or two information digits

x = ANI
Note: The FXO interface generates such MF digits when the
Enable911PSAP parameter is set to 1.
 [2] Double Wink = Double-wink signaling. This is applicable to FXS
interfaces only. The FXS interface generates the first Wink upon
detection of an off-hook state in the line. The second Wink is
generated after a user-defined interval (configured by the
TimeBetweenDIDWinks parameter) after which the DTMF/MF digits
are collected by the device. Digits that arrive between the first and
second Wink are ignored as they contain the same number. For
example:
(Wink) KP 911 ST (Wink) KP I(I) xxx-xxxx ST (Off Hook)
 [3] Wink & Polarity=

FXS: The FXS interface generates the first Wink after it detects
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.
[TimeBetweenDIDWinks]
Defines the interval (in msec) for wink signaling:
 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.
