NUMBER CORRESPONDENCE
The ELVOX TWO-WIRE system uses an audio/video door entry
system numbering scheme based on the physical address of
each device, and ranging from 1 to 200. This applies irrespective
of the fact that there are two numbering modes: (up to) 4 and
(up to) 8 digits. The DIGIBUS system on the other hand identi-
fies audio/video door entry systems by means of an address of
4 digits (up to 9,999) or 8 digits (up to 99,999,999). There are va-
rious ways of getting these two quite different systems to work
together.
1.
We can remap only those DIGIBUS numbers needed to
enter the DIGIBUS 4 or 8 digit code in the position in the
table described in section 5.5 and corresponding to the
ELVOX TWO-WIRE number intended. It is irrelevant whether
we encode the ELVOX TWO-WIRE audio-video door entry
system first or complete the table first.
2.
The programming described in sections 5.3 and 5.4 defines
a range of DIGIBUS numbers corresponding at the most to
the physical numbers 1 to 200.
If the position in the table in section 5.5 corresponding to the
caller is programmed, the address contained in it is used for
messages from the ELVOX TWO-WIRE system to the DigiBus. If
the initial number has been programmed, the calling DigiBus ad-
dress takes this number, adds the ELVOX TWO-WIRE address
and subtracts 1. For example, if the initial number is 1234 and
the ELVOX TWO-WIRE address is 79, the DigiBus address used
is 1234 + 79 – 1 = 1312. In other cases the message is not for-
warded to the DigiBus network. Reference to the table in section
5.5 is also made to forward messages coming into the ELVOX
TWO-WIRE system from the DIGIBUS network. 5. If the number
is found in the table, the corresponding index is used as desti-
nation. Otherwise the initial and final numbers are evaluated and
set respectively to 1 and 200 if not programmed. If the DigiBus
number falls within the interval between the initial and final num-
bers inclusive, the ELVOX TWO-WIRE address takes this num-
ber, subtracts the initial number and adds 1. For example, if a call
arrives for 1312, then 1312 – 1234 + 1 = 79. In other cases the
call is not forwarded to any destination.

FUNCTION CORRESPONDENCE
The ELVOX TWO-WIRE system’s F1 and F2 commands are tran-
slated into the corresponding DigiBus F1 and F2 commands.
The first 6 actuators are translated as F3, F4, …, F8.

8. FUNCTIONING WITH SWITCHBOARD
Proceed as follows to perform the basic functions when using
the interface in conjunction with the DigiBus 945B switchboard.
8.1. CALLS FROM ENTRANCE PANEL
•
The switchboard operator receives the call.
•
He speaks with the external speech unit.
•
He calls the internal number required by pressing the
button on its own or by entering the number on the
keypad and then pressing
.
.
•
He presses
to connect the entrance panel and the in-
ternal user.
8.2.INTERCOMMUNICATING CALLS VIA THE SWITCHBOARD
Two internal users on the same ELVOX TWO-WIRE system can
call each other by means of a specially programmed button.
They can also, however, ask the switchboard operator to put
them in touch. The steps required to do this are as follows.
• The switchboard operator receives a call, makes a call direc-
tly, or takes a call from the queue.
• When the first user answers, the operator then enters the
number of the second user, and calls him by pressing
.
The first user enters wait status and the second user system
rings and waits for a reply.
• As soon as the second user replies, the operator presses
to place the two users in communication.
