The deskphones display the screen savers for approximately 5 seconds at a time at random
locations on the screen, so that the entire image is always displayed. When the phone removes
the screen saver, the phone restores the previously displayed screen unless a specified software
operation such as making a call from the Phone screen displays some other screen.
You can administer color images for gray scale sets or black and white images for color sets. The
deskphone will present the images as applicable for their displays.
To determine what image to display, the deskphone adheres to this procedure:
1. During start-up, the deskphone checks for the file named in the system parameter
SCREENSAVER. If the deskphone finds a file, the deskphone checks that file for valid jpeg
format, and to verify that the screen saver image height and screen saver image width do
not exceed the specifications.
The screen saver should be a smaller size than these pixel values specified so the screen
saver can move randomly while displaying the entire image.
2. If the deskphone does not download a valid file, either because no file exists, or because
the downloaded file exceeded one or more of the pixel count limits, or because the image
is not a valid JPEG image, the deskphone uses the Avaya-specific screen saver.
About administering audio equalization
The Federal Communication Commission (a branch of the US Government) in its Part 68
standard, has made Hearing Aid Compatibility (HAC) a mandatory requirement. The HAC feature
is an alternative way to provide audio equalization on a handset, from the acoustic standards
specified in TIA-810/920 and S004, and may be of benefit to some users of t-coil capable hearing
aids.
Release 6.2 onwards, the IP deskphones support the ability to choose either of these standards.
Because individual organizations and users differ in how they might want to implement this choice,
the deskphone provides 3 ways to specify the desired audio equalization:
•
Settings File
: The administrator can set ADMIN_HSEQUAL. The default value, 1, specifies
Handset equalization that is optimized for acoustic TIA 810/920 performance unless
otherwise superseded by Local Procedure or User Option. The alternate value, 2, specifies
HAC and 3 specifies Amplified.
•
Local Procedure
: When users are denied access to Options for administrative reasons, but
individual users need an equalization value other than the one in the settings file, the
HSEQUAL Local Procedure provides another method to administer the deskphone with the
audio equalization value that you require. “Default” uses the settings file value unless
superseded by User Option. “Audio Opt.” is optimized for TIA-810/920 acoustic performance,
“HAC Opt.” is optimized for HAC telecoil performance, and “Amplified” is optimized for setting
nominal volume level between calls.
•
User Option
: The user can select “Default” by which the deskphone uses the settings file
value unless superseded by Local Procedure), “Audio Opt.” which uses Handset equalization
that is optimized for acoustic TIA 810/920 performance, or “HAC Opt.” which uses Handset
equalization that is optimized for electrical FCC Part 68 HAC telecoil performance.
