Flash – Analog Port (SLT) Flash Recognition
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 DX-80 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 DX-80 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.

Conditions
a) 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.
b) 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.
c) Use the default Start and End timing wherever possible.
Default Settings
Call Handling – Category 2 – SLT Hook Flash Start is set to "200." (Range is: 60, 100-1400 milliseconds.)
Call Handling – Category 2 – SLT Hook Flash End is set to "1000," COS 1-7 are set to "No." (Range is: 100-
1500 milliseconds.)
Programming Abstract
Program the necessary Start and End detection period to assure accurate hook-flash detection at analog
devices. (Analog devices typically send hook flash commands at 600-900 milliseconds, so a Start time of
"200" and an End time of 1000 is usually sufficient.)
