I. OVERVIEW
DSS80 Module, which is indeed a keypad consisting of 80 keys and corresponding
LEDs, is mainly designed to be used together with Karel LT48 & LT48-H Feature
Phones and OP48 & OP48-H Consoles.
Figure 1 illustrates the outlook of a DSS80 Module.

I.1. DSS80 KEYS
1. Each DSS80 key can be programmed to have two different functions:
Primary
Function
and
Secondary Function
. While programming the keys, if a feature
is to be assigned to the
Primary Function
of a key, the key should be pressed
until the first “beep”
. However, the same key should be pressed
until the
second “beep”
if a feature is to be assigned as a
Secondary Function
.
In the following pages, programming the Primary Function of a key is
explained.

2. If the feature assigned to the
Primary Function
of a key is to be activated, the
key should be pressed
until the first “beep”
. However, the same key should
be pressed
until the second “beep”
if the feature assigned to its
Secondary
Function
is to be activated.
In the following pages, activating the Primary Function of a key is explained.
3. The features can be activated in two ways:
-
Lifting the handset of the telephone and then pressing the relevant key on
DSS80, or
-
Pressing the relevant key on DSS80 and then lifting the handset of the
telephone in 3 seconds. This method eliminates the necessity of handset
use first; thus enables one-hand operation.
In the following pages, the first method is used to explain how to activate the
features.
4. The
LEDs
, corresponding to the DSS80 keys,
function only for
the features
assigned to the
Primary Functions
of the keys.
5. Though there are many identical keys on DSS80, some of them have special
uses which take effect during programming of DSS80. These keys are
identified by the characters written on the labels.
There are two groups of keys for such special use:
-
DSS80 Numeric Keys: These keys have numbers “
0, 1,..., 9
” as indicators.
These keys can be used to enter parameters during programming of DSS80.
-
DSS80 Programming Keys: These keys have letters
“S, T, C, M, P, E, A, R”
as indicators. These keys can be used to enter and exit programming mode
of DSS80. (See
Section II
as well to enter and quit
Programming Mode
.)
