6.14 Establishing Start and End of SLT Hook Flash
Single Line Telephones and similar analog devices connected to analog ports of the DX-80 system must use unso-
phisticated signaling to administer call-processing operations (like transfer and hold). This fundamental call
control is handled in the form of specific hook-switch operations. These are known as hook-switch flash (or just
flash) commands.
Whenever extension users want to invoke a system feature at a single line telephone, they must operate the hook-
switch in a fashion that is distinguishable from an on-hook (hang up) request. This becomes essential for proper
handling of calls, considering the user may operate the hook-switch quickly to hang up and place a new call. Yet
this fast operation of the hook-switch might be interpreted as a hook-switch flash operation.
Considering these factors, the DX-80 system allows you to customize the hook-switch command monitoring. You
can direct the system to ignore hook-switch operations that are considered too short to be valid, and to limit the
time allotted.
The following conditions apply to SLT hookswitch flash.
• If the analog device/SLT does not have a hook-flash operation button, extension users must operate the hook-
switch within the time you specify in the “Start” and “End” settings. If they do not, the system does not
process the user’s action as a valid hook-flash operation.
• The system ignores hook-switch operations that are shorter than the “Start” time.
• The system considers hook-switch operations that are longer than the “End” time as hang ups.
6.14.1 PROGRAMMING USING THE DET
Note: chg , bksp , save , one , always , del , and ack are interactive LCD button operations. Use the three buttons
below the LCD display to actuate the associated operation.
1. Enter Database Administration using the feature code Feature # * and then enter the DB Admin password .
2. Press show . The system displays the DB Item Select screen.
3. Enter 03-14 , then press save . This advances you to the SLT Hook Flash programming screen.
4. Press show . This advances you to the Start screen.
5. Press chg to set the Start range setting. This timer indicates the minimum time that an analog/SLT must
flash the hook-switch to be considered a valid flash-hook request. A hook-flash that is shorter than this
timer is considered a mistake; no action is taken. Valid options include from 60 - 1400 milliseconds. The
default is 200 milliseconds.
6. Press next . This advances you to the End screen.
7. Press chg to set the End range setting. This timer indicates the maximum time that an analog/SLT must
flash the hook-switch to be considered a valid flash-hook request. A hook-flash that is longer than this
timer is considered a hang up. Valid options include from 100 - 1500 milliseconds. The default is 1000 mil-
liseconds.
8. Press the Hold button to return to the previous menu level,
Or, press the Volume button (up or down) to return to the DB Item Selection screen,
Or, exit programming.
