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.)
