Carry out the actions that are depicted as symbols in left-to-right order. Symbols that are
located under one another are available as alternatives. Change these symbols for the ones
that are directly above them in the first row, depending on what you want to set or who you
want to call. The symbols are described in more detail on the fold-out cover flap.
In addition, you will find here descriptions of a few programming functions that are indicated
by the initial password that you have to enter. Depending on the instruction, lift the handset
on the relevant telephone set or on the programming telephone. After entering the initiating
digit – a 7 or an 8 – and the valid password, the system outputs an acknowledgement tone
(a pulsating tone). After you enter the rest of the programming digits, you hear another
acknowledgement tone. You now have the option of ending programming by replacing the
handset or immediately entering another sequence of programming digits (omit the initiating
digit and the password), assuming that this sequence is initiated with the same digit and
password. If you hear an engaged tone, you have made a mistake (entered the wrong digit
or similar). Replace the handset and repeat the programming step.
Except for the ETS-2106 I Rev. 2, you can connect to your PBX ISDN telephones as well as
analog pulse dialling and DTMF ones. As a result, there are several differences in operation.
If you are already involved in a call with another (internal or external) party, on a DTMF tel-
ephone you must first press the Flash key (
F
key, signal key) before punching in a digit for
transferring the call. Pulse dialling telephone sets do not have a Flash key and they do not
need them. This means that if you have a pulse dialling telephone set connected to your
PBX, you do not need to press the Flash key. Any deviations with pulse dialling telephones
are shown in square brackets ([ ]).
There are wide variations in the operation of ISDN telephones. With some of them, you use
function keys to operate them, whereas others have menu-driven operator guidance, i.e.
prompts are displayed on your telephone set that tell you which button to press, for example.
You normally use an
F
key, for example, to initiate a query. In a few cases, this key is also
referred to as the hold key. On some ISDN telephones, the query is menu-driven. You end
the query by pressing what is known as the cut-off key. In some cases, the system also
prompts you in a menu.

To be able to carry out programming, the programming switch in the system on the
PCB must be in the “erlaubt” (allowed) setting (Chapter First Use on page I-26 in the Instal-
lation and Configuration Manual).
