Introduction
This owner’s manual covers the installation, programming, and operation of DYNACORD’s DTI
2000 Digital Telephone Interface. Since operating and programming the DTI 2000 is similar to the
operation and programming of a paging console, the DPM 4000 System handbook, the DPC 4000
paging console owner’s manual, and the Help Files of the PC Designer software may also be useful
information sources.
Characteristics
The DTI 2000 is a micro processor-controlled, completely configurable telephone interface for
DYNACORD PA-systems and sound reinforcement systems. The DTI 2000 is used for connecting the
DPM 4000 System Manager to a telephone line or network to launch announcements from each
telephone set over the loudspeaker network and to trigger signals, pre-recorded text messages and
control functions (macros) of the DPM 4000 System Manager using a telephone set.
The DTI 2000 needs to be connected to an analogue phone line and is controlled via tone-dial (multifrequency dialling). Using the supplied cable, the telephone interface has to be connected to a paging
console input on the DPM 4000. The interface transmits serial control data as well as LF-audio
signals. The DTI 2000 appears at the DPM 4000 as a special paging console allowing it to be
programmed via the PC Designer Software in paging console dialog mode.
The DTI 2000 offers 100 call numbers (from 00 to 99). Any function can be assigned to any call
number. Possible functions include zone or group selection, live-announcements with preprogrammable priority and pre-chime signal, playback of pre-recorded text messages and triggering of
DPM 4000 macros. The DTI 2000 offers two different access authorisations with individual password
protection. Depending on the actual application and desired operation, the DTI 2000 allows initiating
any possible function from a standard telephone set – from making a simple announcements up to
triggering a sound reinforcement installation’s most complex sequential control procedures.
Features
· Selection of up to 100 zones for announcements
· Programming of up to 20 call groups for group calls and collective calls
· Configuration of a call number organisation chart of up to 100 numbers (0 ... 99) for
announcements and arbitrary control functions
· Selecting several zones or groups for announcements
· Initiating the playback of pre-recorded text messages
· Triggering of special functions (macros, erase zone / group selection)
· Assigning priorities for announcements and message playback
· Two level password protection
· Acknowledgement signals for O.K., faulty entry, busy, outgoing text message, etc.
· Automatic hang up: to specify the duration of announcements via internal Dip switches
· Trimmer on the front panel for setting the audio signal level
· Programming via PC Designer Software equivalent to DPC 4000 paging consoles
· Configuration possibility for world telephone standards (country-specific settings)

Controls and Connections
front view
1. POWER indicator
The POWER LED lights when the DTI 2000 receives power input from the supplied power supply
unit, which allows worldwide connection and use because it accepts input voltages between 85V
AC and 250V AC.
2. SEIZE / DROP key (SELECT)
This key allows manually accepting or cancelling phone calls and is mostly used for testing. When
an incoming phone call is present (ringing), pressing the SEIZE / DROP key establishes the
connection (picks up). Pressing the SEIZE / DROP key again cancels (hangs up) a live connection.
Since the DTI 2000 automatically picks up any incoming call respectively automatically hangs up
when the remote call is terminated, this key is basically not needed during normal operation.
3. DROP and SEIZE indicators
The red DROP LED indicates that there are no live connections (i.e. the DTI 2000 is on-hook).
The green SEIZE LED indicates that the DTI 2000 established a connection to the calling party
(i.e. the DTI 2000 is off-hook). The DTI 2000 automatically connects to incoming phone calls.
Using the internal DIP-switch S202 allows specifying the number of rings prior to accepting a call.
4. TALK indicator
The orange TALK LED lights whenever the DTI 2000 is in announcement mode (i.e. when an
announcement into a single or several zones of the PA-system has been initiated via telephone
connection).
5. LEVEL control / meter bars
Audio signals that are transmitted from the DTI 2000 to the DPM 4000 System Manager can be
monitored using the TO PAGING MANAGER meter bar. Level adjustment is possible via the
associated LEVEL control on the front panel using a small screwdriver. The level setting range is
between ***dB (counter clockwise stop) and ***dB (clockwise stop).
Currently, the TO TELEPHONE indicator and the associated level control are not used.

6. TO PAGING MANAGER connectors, female
The two TO PAGING MANAGER connectors represent the interface to the DPM 4000 System
Manager. Using either the 9-pole D-Sub connector or the 6-pole RJ-12 socket (simultaneous use
of both terminals is not possible) to establish audio and data connection to the DPM 4000 is
possible. The DTI 2000 needs to be connected to one of the paging console inputs (DPC IN, RJ-45
socket) on the DPM 4000. The needed interface cable (RJ-12 to RJ-45) with a length of 3.5m is
supplied.
7. DATA indicator
The DATA LED indicates that data is being transmitted between DTI 2000 and DPM 4000
System Manager. Therefore, it serves as main monitoring indicator for correct data connections.
8. DIP switch for address and operation mode settings
The DTI 2000 allows setting an address between 1 and 16. CAUTION: Make sure never to
connect two or more appliances with identical address settings to the DPM 4000 System Manager,
since this would inevitably result in data conflicts. This also includes the address settings of the
connected paging consoles.
Please refer to the chapter DIP-switch settings for further details.
9. Phone sockets
Two telephone connectors are located on the rear panel of the DTI 2000. Connect the PHONE
LINE socket with your telephone wall outlet. The LOOP THRU socket offers connection for a
telephone set.
10. POWER SUPPLY connector
Connect the supplied power supply unit to this connector by inserting the round plug of power
supply unit into the POWER SUPPLY socket on the rear panel of the DTI 2000. Turn the plug’s
locking ring in clockwise direction to establish a reliable connection. Afterwards, connect the
supplied mains cord to the power supply unit before inserting the mains plug into a mains wall
outlet.

Se Up and Connections
1. Unpacking
The DTI 2000 package contains the following parts:
1 DTI 2000 Digital Telephone Interface
1 power supply unit, 100 – 240V AC
1 IEC mains cord
1 interface cable for DPM 4000 connection, RJ-12 to RJ-45

1 owner’s manual
Make sure that everything is complete and that nothing is damaged. Otherwise, immediately
contact your dealer or the TELEX / EVI Audio service department.
2. DIP switch settings
The DTI 2000 provides a single DIP-switch on the rear panel and two internal DIP-switches.
Theses switches are meant for making specific basic settings, which have to be made before
operating the appliance for the first time. Generally, no changes need to be made during the later
operation.
2.1 DIP switch for address and operation mode settings on the rear panel (S201)
A switch is “OFF” when it is set to its upper position. Consequently the ON-position is down.
The following table shows how to set addresses using the switches 1 – 4:
SW1 SW2 SW3 SW4 ADDRESS
OFF OFF OFF OFF 1
ON OFF OFF OFF 2
OFF ON OFF OFF 3
ON ON OFF OFF 4
OFF OFF ON OFF 5
ON OFF ON OFF 6
OFF ON ON OFF 7
ON ON ON OFF 8
OFF OFF OFF ON 9
ON OFF OFF ON 10
OFF ON OFF ON 11
ON ON OFF ON 12
OFF OFF ON ON 13
ON OFF ON ON 14
OFF ON ON ON 15
ON ON ON ON 16
Switches 5 – 7 provide no function and should be left in their OFF-position (up).
CAUTION:
Make sure never to connect two or more
appliances with identical address settings to
the DPM 4000 System Manager, since this
would inevitably result in data conflicts.
This also includes the address settings of the
connected paging consoles.
Switch 8 serves for switching between normal operation and download mode. Leave this switch
(SW8) in its OFF-position (up) for normal operation. Download mode is meant for updating the
software and loading country-specific settings by DYNACORD or one of its service centers.
