About Administering Audio Equalization - Avaya 9608 Administrator's Manual

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 9600 Series 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superseded by Local Procedure or User Option.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.
• 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 as documented in the Installing and maintaining Avaya IP
Deskphone 9608, 9608G, 9611G, 9621G, and 9641G H.323 for 9608, 9611G, 9621G, and
9641G deskphones 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, and "HAC Opt."
is optimized for HAC telecoil performance.
• 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.
