Flash – Analog Port (SLT) Flash Recognition
7.14
Description
Flash refers to the command issued at an analog device to invoke system features.
Flash is the momentary operation of the hook‐switch at an analog device.
Conversely, the on‐hook command at an analog device signifies an on‐hook
(disconnect/hang‐up) request.
The momentary operation of the hook‐switch at the analog device is deciphered
by the Emerald ICE system in such a way that the previous call in progress is held,
or placed in a status of transfer awaiting further instructions from the user.
Flash Recognition is the specific timing associated to a user flash request. The
Emerald ICE must be setup to decipher a flash command from an on‐hook
command where the user may go on‐hook then immediately off‐hook again to
place a call.
There are two settings in the flash recognition timing: the Start Time and the End
Time.
The Start Time can be set very low to detect very fast operation of the hook‐switch
but care should be taken when using low Start settings since the timing may allow
line noise to trigger a flash command.
The End Time can be set very high to detect very slow hook‐flash operations but
care should be taken when using high End settings since the timing may not allow
the triggering of On‐Hook commands in an acceptable period for the user.
Use the default Start and End timing wherever possible.
Default Settings:
SLT Hook Flash Start is set to 200. (Range is: 60, 100‐1400 milliseconds.)
SLT Hook Flash End is set to 1000, COS 1‐7 are set to NO. (Range is: 100‐1500
milliseconds.)
