used at any time prior to pressing <SEND> to cancel
the call.
To locate a user in the database more quickly, you can
enter one or more of the first few digits/letters of the
User ID/Name prior to pressing the right <SCROLL>
button. The DDU will search the database for users
matching the first few digits/letters.
4.2.3 Calling a Unit Not in the Database
To place a call to a unit which is not in the database,
start by selecting CALL from the Main Menu or by
pressing a number key while in display mode. Instead
of pressing the right <SCROLL> button, simply key the
numeric ID of the user to be called using the keypad.
Press <SEND> to initiate the call. The left <SCROLL>
key may be used as a backspace key to correct any
errors made during entry. The <#> key may be used at
any time prior to pressing <SEND> to cancel the call.
4.2.4 Numeric vs. Alphanumeric Entry
There are two different data entry modes available on
the DDU. As shipped from the factory, Numeric entry
is the default mode when calling a unit. As numbers
are entered, they appear on the bottom-left of the
display. Pressing the <*> key while in numeric entry
mode changes the mode to Alphanumeric.
In alphanumeric mode, you may type in letters and
numbers as described in the next section. This allows
you to type the name of a user in the database without
having to scroll through the names. Alphanumeric data
appears on the bottom line of the display as it is
entered. You may make alphanumeric call entry the
default mode by changing the Call Entry Mode setting
in the CONSOLE SETUP menu.
4.3 U
SER
D
ATABASE
The user database makes day-to-day operation of the
DDU much easier. You can use easy-to-remember
names instead of just numbers.
4.3.1 User Database Features
The primary purpose of the user database is to
associate names with numbers. This way, when an
ANI comes in, the name of the person can be
displayed along with the ANI.
The DDU can store up to 137 names and ID numbers
in its database. The DDU retains the database
memory even when switched off.
4.3.2 Setting Up the User Database
Begin by compiling a list of names and ID numbers.
Give some thought on how you are going to abbreviate
the names since only 14 characters per name are
available. To begin entering data, select Add User
from the USERS menu.
4.3.3 Entering Alphanumeric Data
Entering alphabetic characters into the user database
using the numeric keypad is easy. All of the letters of
the alphabet appear above the numbers on the
keypad. For example, the letters ‘A’ ‘B’ and ‘C’ appear
on the <2> key.
Alphabetic characters are entered by pressing 2 digits.
The first digit is the key with the desired letter
appearing on it. The 2
nd
digit is the position of the letter
on that key. For example, the code for the letter ‘C’ is
23 since it is the 3
rd
letter on the <2> key. The letter ‘T’
is the 1
st
letter on the <8> key, so its code is 81.
To enter numeric characters in an alphanumeric field,
press the <0> key followed by the desired digit.
Punctuation characters such as comma <,> and <->
do not appear on the keypad. Special codes have
been assigned to allow entry of those characters.
Please refer to the following chart
A=21 I=43 Q=72 Y=93 7=07 - =15
B=22 J=51 R=73 Z=94 8=08 = =16
C=23 K=52 S=74 1=01 9=09 * =17
D=31 L=53 T=81 2=02 0=00 / =18
E=32 M=61 U=82 3=03 , =11 # =19
F=33 N=62 V=83 4=04 . =12 Spc=10
G=41 O=63 W=91 5=05 _=13
H=42 P=71 X=92 6=06 +=14
The code 10 is used to insert a space between
characters.
4.3.4 Numeric vs. Alphanumeric Entry
There are two different data entry modes available on
the DDU. Numeric entry is for entry of User ID codes.
Alphanumeric entry is used when entering User
Names to the database. When selecting a user in the
database to be edited or deleted, either mode may be
used.
As shipped from the factory, numeric is the default
mode for selecting a unit to edit or delete. As numbers
are entered, they appear on the bottom-left of the
display. Pressing the <*> key while in numeric entry
mode changes the mode to Alphanumeric. You may
make this the default by changing the Data Entry
Mode in the CONSOLE SETUP menu.
