INTRODUCTION
This manual describes the installation, programming, and
operating procedures for the RTS Model TIF 2000A Digital
Hybrid Telephone Line Interface. Since TIF 2000A
functions as a keypanel, the user may also need to refer to
the manuals and/or on-line help files for AZedit for infor-
mation on configuring certain features.
INSTALLATION
Rear Panel DIP Switch (S201)
The rear panel DIP switch contains switches to configure
the most often changed options. These include: auto answer
on/off, ring signal on/off, password on/off, intercom port
address, and full duplex method.
Auto Answer
Turning on the auto answer option will set the unit to
answer the phone automatically when it rings. The number
of rings required before it answers is determined by the
setting of internal DIP switch (S202). If auto answer is
turned off, the line will ring until someone at a keypanel
answers the call or until the Select button on the
TIF 2000A’s front panel is pressed. To turn ON auto answer,
place switch 1 in the down position. To turn OFF auto
answer, place switch 1 in the up position.
Generate Ring Signal
Turning on the generate ring signal option sets the unit so
that when the phone line is ringing, keypanels that are
configured to receive ring signals will produce an audible
ring. To turn ON the ring signal, place switch 2 in the down
position. To turn OFF the ring signal, place switch 2 in the
up position.
Password Required
Turning on the password required option sets the unit so that
when a call is automatically answered, the user must enter a
password via DTMF before the unit will allow communica-
tions. The password numeric sequence and length are
determined by the settings of internal DIP switch (S203). To
turn ON the password required option, place switch 3 in the
down position. To turn OFF the password required option,
place switch 3 in the up position.
Intercom Port Address
Switches 4 to 7 determine the address of the unit. The port
address is expressed in binary with switch 4 being the least
significant bit (LSB) and switch 7 being the most significant
bit (MSB). To turn ON (set bit to 1), place the desired
switch in the down position. To turn OFF (set bit to 0), place
the desired switch in the up position. ADAM, ADAM CS,
and Zeus units use a 1-8 address scheme for their ports (e.g.
ports 1-8 have addresses 1-8, ports 9-16 have addresses 1-8,
etc...). CS 9xxx systems use a 1-10 scheme for port ad-
dresses (e.g. ports 1-10 have addresses 1-10, ports 11-20
have addresses 1-10, etc...).
To set the address for ADAM, ADAM CS, or Zeus systems
do the following:
1. Determine the port number that will be used for the
TIF 2000A.
2. Locate the port number and its corresponding address in
Table 1.

DESCRIPTION
The TIF 2000A is a single line digital hybrid telephone line
interface designed to be compatible with ADAM,
ADAM CS, ZEUS, and CS 9000 series intercom systems. It
provides bi-directional communication between the inter-
com matrix and a standard DTMF capable telephone line. It
allows the phone to access all crosspoints of the matrix, as
well as dynamic party lines, IFB circuits, and other forms of
communications. The 1U high by ½ wide rack mountable
(via an optional kit) TIF 2000A provides a transparent link
to the telephone system enabling full dial-out capability
from any designated keypanel with keypad. The TIF 2000A
has full dial-in capability giving the caller a keypanel on the
system via commands from the DTMF pad on their tele-
phone. Since the TIF 2000A appears to the matrix as any
other keypanel would, the only limitation on the number of
units in the system is the same as for other keypanels.

lowering the back of the cover. Replace and tighten the
screws that were removed or loosened as indicated in
Figure 3.
Ring Count
Switches 1 and 2 determine the number of rings before the
unit auto answers. NOTE, the ring count is approximate.
These switches have no effect unless switch 1 on the rear
panel DIP switch bank is in the down position. To set the
ring count, consult Table 3.
DTMF or Pulse Dial Selection
Switch 3 sets the dialing mode to either Dual Tone Multi-
Frequency (DTMF) or Pulse. When in the switch is in the
Off position DTMF dialing is selected. When the switch is
in the On position pulse dialing is selected.
3. Determine the DIP switch settings by looking up the
address determined in the previous step in Table 2.
4. Set the DIP switches on the back of the unit.
To set the address for CS 9xxx systems do the following:
1. Determine the intercom intercom port (audio channel
number) that will be used for the TIF 2000A.
2. For port numbers ending in 1 through 9, the address is the
last digit of the port number. If the last digit is zero, use
10 as the address number
3. Determine the DIP switch settings by looking up the
address in Table 2.
4. Set the DIP switches on the back of the unit.
Full Duplex Method
Switch 8 (S201) controls the method by which full duplex
operation is implemented in the unit. This switch only
works if full duplex mode is set via internal DIP switch
(S202), switch 7 (factory default setting for Switch 7 is ON,
full duplex mode.) If switch 8 is in the open position, then
the unit will be forced into full duplex mode all the time. If
switch 8 is in the closed position, then the unit will be
forced into full duplex mode only when audio is present.
When using full duplex mode, users may hear an increased
amount of echo on the line. This may be more pronounced
when the TIF 2000A is forced into full duplex mode all of
the time (switch 8 open) rather than only when audio is
present (switch 8 closed).
Internal DIP Switch (S202)
Internal DIP switch (see Figure 4) is accessed by removing
the top cover. To remove the top cover, remove and loosen
the screws as indicated in Figure 3. Remove the cover by
lifting up on the back portion of the cover. To reinstall the
cover, place the front portion into the grooves on the bottom
cover and slide the cover toward the front of the unit while

Point-to-Point Seize
Switch 4 turns on and off the Point-to-Point Seize feature.
When the switch is in the OFF position normal line seize
operation (via a keypanel) is selected. When the switch is in
the ON position a line will be seized immediately upon the
designated TIF 2000A’s talk key being pressed via the
keypanel.

OneTouch Dial
Switch 5 enables/disables the One Touch Dialing feature.
When the switch is in the OFF position One Touch Dial is
disabled. When the switch is in the ON position One Touch
Dial is enabled.
One Touch Dial works as follows:
If a number is stored in Auto Dial memory 1 on the
TIF 2000A, and the line is on hook, then the TIF 2000A
will autodial the number stored in Auto Dial memory 1
whenever any keypanel closes a point-to-point talk key to
the TIF 2000A.
Fast Seize
Switch 6 enables/disables the Fast Seize feature. If the
switch is in the OFF position Fast Seize is disabled. If the
switch in the ON position Fast Seize is enabled. If Fast
Seize is enabled and the unit is set to auto answer, then the
TIF 2000A will answer or “seize” the line at the start of the
first ring. It is important to note that a ring will not be heard
on any of the keypanels.
DSP Full or Half Duplex Selection
Switch 7 determines either full duplex or half duplex
operation. If the switch is set to the OFF position, the DSP
is forced into full duplex mode as determined by the setting
of switch 8 on the DIP switch bank located on the rear panel
of the TIF 2000A. See Full Duplex Method for more
information. If the switch is set to the ON position, the DSP
is never forced into full duplex mode.
Audio Ducking
Switch 8 enables/disables theAudio Ducking feature. If the
switch is set to the ON position, Audio Ducking is disabled.
If the switch is set to the OFF position, Audio Ducking is
enabled. TheAudio Ducking feature helps to eliminate
feedback between the intercom system and the telephone
line.
Internal DIP Switch (S203)
Internal DIP switch (S203) selects the password. It has no
effect unless password required has been enabled on the
DIP switch located on the rear panel. When password
required is enabled, the password must be entered via
DTMF by the caller before they may communicate. This is
to prevent unauthorized use of the intercom by callers. See
Table 5.
Switches 7 and 8 select the length of the password, from 1
digit to 4 digits. If set for 1 digit only the first digit of the
password is used, if set for 2 digits, then the first 2 digits are
used etc. See Table 4.
Rack Mounting
There are two options for rack mounting the TIF 2000A. If
a single unit is to be rack mounted attach an MCP-2 rack
mount kit. If two units are to be mounted side-by-side,
attach an MCP-1 rack mount kit. See Figure 5 for a depic-
tion of the two rack mount kits.
Connections
Intercom
Use either of the “To Matrix” connectors (but not both) to
connect to an intercom port. The intercom port that you
connect to will determine the address of the unit (see
Setting Address). Cable wiring diagrams are shown in
Figure 5 - Rack Mount Kits
Table 4 - Password length DIP Switch Settings
Figures 6 and 7. An LED labeled “Data” is located next to
the Matrix connectors and serves as a basic indicator of data
flow.
Telephone andTelephone Line
There are two telephone connections provided on the rear of
the TIF 2000A. Plug the telephone line into the jack labeled
“To Phone Line”.You may also plug a standard telephone
into the jack labeled “Loop Thru”.
Note: The standard telephone plugged into the “Loop Thru”
jack is disconnected when the TIF 2000A seizes the
telephone line.
Power Supply
Insert the round connector from the brick type power supply
into the power connector on the rear of the TIF 2000A. Turn
the locking ring on the connector to secure the connection.
Plug the female end of the IEC type power cord into the
power supply and then plug the other end into an appropri-

9
ate power outlet.
Setting Audio Levels
Audio levels to the intercom matrix and to the telephone
line can be adjusted via the trim pots located on the front
panel.
Setting audio levels to intercom matrix
Adjustment may be made via the front panel control (see
Figure 1). To adjust the control use a small flat blade
screwdriver or trim pot adjustment tool. Initially set the
front panel level control for mid range. Have the caller talk
at their normal level and adjust the control for the best audio
quality while avoiding going into the red section of the
audio meter (to Matrix) located on the front panel.

Setting audio levels to telephone line
Adjustment may be made via the front panel control (see
Figure 1). To adjust the control use a small flat blade
screwdriver or trim pot adjustment tool. Initially set the
front panel level control for mid range. Talk at your normal
level and adjust the control for the best audio quality while
avoiding going into the red section of the audio meter (to
Telephone) located on the front panel.
Configuring for Country’sTelephone System
The TIF 2000A should be configured to work with the
telephone system to which it is connected. Each country or
area of the world has unique signaling differences that could
cause erratic operation of the TIF 2000A if it is not properly
configured. If the system you intend to connect is not
currently supported, you may request a configuration using
the form located in the back of this manual.
To configure the unit for use with a specific country’s
telephone system do the following:
Note:AZedit must be configured to allow firmware
downloads.
1. Connect the TIF 2000Ato the intercom system.
2. Run the AZedit software and go to the keypanel
software versions screen. This is located under the Status
menu. Go to |Status| |Software Versions| |Keypanels|.
3. Click on the entry for the TIF 2000A you wish to
configure.
The configurations are in a self extracting archive on the
included floppy disk.
4. Extract and copy these files to a known location on the
computer connected to the intercom matrix
5. Press CTRL + SHIFT + Dto start the software down-
load process. A download screen should appear.
6. Select the location that you copied the files to in step 4
and select the file corresponding to the country needed.
7. Click OK.
Once the software versions window reappears, the process is
complete.
The status reported for the TIF 2000A contains a number
corresponding to the country configuration. This is reported
as LOCALE = XX where XX is a specific number for each
country. The current possible configurations are:

OPERATION
Operation From A Keypanel
The TIF 2000A is operated from the intercom keypanels,
and from the dial pad on the telephone at the remote end of
the line. Any keypanel with a keypad may use a TIF 2000A.
All that is necessary is to program a key to talk to the
TIF 2000A, as if it were a keypanel. The alpha numeric
display or tally LED for that key then provides information
about the phone line. A solid display or non illumined LED
indicates a line which is not in use. A slow flash indicates a
line which is in use (off hook).A rapidly flashing display or
LED indicates a line which is ringing. In addition, the alpha
numeric display will display digits as they are dialed, and
the LED will flash for each digit.
Note: Displayed tallies will be different if the “Don’t
generate tallies for TIF or trunk use” option has been
selected in |Options| |Intercom Configuration|.
Programming a key to use the TIF 2000A
To use the TIF 2000A, either to answer a call, or to call out,
you first need to program a key to talk to the TIF 2000A.
This is accomplished in the same manner as programming a
key to talk to a key panel. To program a key by port number,
enter NUM-nnn-PGM-t, where NUM is the number 1 key,
nnn is the port number of the TIF 2000A you want to use,
and t is any talk key. In general, you will also need to use
the listen key, so it should be assigned as either AF (auto
follow), orAL (auto listen).
Note: The TIF 2000A only responds to commands which
are sent via a point-to-point key assignment. If you wish to
use the TIF 2000A primarily on a PL, you must add a point
to point assignment as the L2 talk assignment on the talk
key for any panels which are going to either answer the line,
or dial out on the line.

11
Dialing a call
Any key panel may dial calls on the TIF 2000A.
To dial a call on the TIF 2000A;
1. Turn on the listen key for the line you wish to dial on.
This will allow you to hear dial tone, and your DTMF
dialing tones.
2. Enter dial mode by entering PHONE-PGM-T. PHONE
is the 4 button on the keypad. PGM is the red PGM key
on the keypad, and T is the talk key which is pro-
grammed to talk to the TIF 2000A you are dialing on.
Leave the talk key in the latched position as you dial the
number.
3. Dial the number. As you enter each digit, it will appear
in the alpha display above the key you are dialing on. If
the listen key is latched, you will hear each DTMF tone
as it is generated.
4. When you have completed dialing, momentarily turn off
the talk key to exit dial mode. The alpha numeric display
will revert to normal, and you may use the key and
keypad in the normal manner.
Note: The keypad is used in the usual way. Digits 0-9
generate the DTMF digits 0-9. PGM generates #, and CLR
generates *(# and * are displayed for these keys).
It is necessary to press CLR twice if you wish to generate a
*, as a single CLR is used to trigger the speed dial and
redial features.
Hanging up
The TIF 2000A will detect that the caller at the far end has
hung up under most circumstances. It detects the hang up
by either loop interrupt, battery reversal, or the presence of
dial tone or a busy signal. Some telephone systems do not
provide any of the above, so it will be necessary to force a
hang up. In addition, if the call was placed to an auto
answer device, it will be necessary to force a hang up when
the call is complete.
Enter PHONE-CLR-t, where PHONE is the 4 button on the
key pad, CLR is the CLR button, and t is the talk key which
is programmed to talk to the TIF 2000A which you wish to
hang up. This will disconnect the line for which you struck
the talk key.
Note: If the talk key is in the ON position, you must turn
off the key, then momentarily turn it on again to indicate
which line you wish to disconnect. If the line is in dialing
mode, then you must first exit dialing mode by turning off
the key, then use PHONE-CLR-t to hang up.
Re-dialing the last number
The TIF 2000A remembers the last number which it has
dialed.
1. Enter dialing mode by following the instructions for
dialing a call.
2. Enter CLR-0-0. The TIF 2000Awill automatically redial
the last number it dialed.
3. Momentarily release the talk key to exit dialing mode.
For example: If you have a call to 818-566-6700 and you
are disconnected, issuing the redial command will reestab-
lish the call. The redial command may be issued from any
keypanel in the intercom, not just the keypanel that origi-
nally dialed the call.
Dialing a speed dial number
The TIF 2000A has 24 internal memories for storing
frequently used phone numbers. To dial one of these
numbers:
1. Enter dial mode.
2. Enter CLR-nn where CLR is the clear button on the key
pad, and nn is two digits, which are the speed dial code.
3. Momentarily release the talk key to exit dialing mode.
Storing a speed dial number
1. After dialing the number the usual way, but before exiting
dial mode, enter the CLR-PGM-nn before you release
the talk key to exit dialing mode.
2. Momentarily release the talk key to exit dialing mode.
Note: To generate a pause during auto dial, enter *99. This
is used for example if you need to enter a digit to get an
outside line, and your phone system requires a pause before
continuing to dial.
Each number may contain up to 25 digits.
A TIF 2000A can have different numbers stored in it.
Unlike the TIF 951, the TIF 2000A stores the numbers in
nonvolatile memory and therefore does not require a UPS to
maintain stored speed dial numbers.
Answering a call
1. When a line is ringing, the alpha numeric display or LED
above the talk key which is programmed for that line will
flash rapidly.
2. To answer the call, first turn on the listen key, then press
the talk key and speak into the microphone or headset.

12
3. If you have been programmed as a default station, your
panel will “ring” whenever one of the lines rings. If you
do not have a key already programmed, the ringing line
will appear on your incoming call key (the key farthest to
the right on the main panel also known as the Call
Waiting Window or CWW). To answer, press the
incoming call key and answer. You should copy the key to
a main key position, either just before or just after you
answer, so you can turn on the listen key to hear the caller
audio.
TIF 2000A System Setup to Receive Calls
To the intercom system, the TIF 2000A is very much like a
keypanel. If the phone lines are to be used for outgoing calls
only, then no programming in AZedit is necessary. If users
are going to phone into the intercom from the outside, then
the TIF 2000A needs to be configured to allow them to use
the phone line in much the same way a local user uses his
key panel.
Programming information for the phone line is entered into
the AZedit software just as if the TIF 2000A were an
ordinary keypanel, by selecting “Keys” from the main
menu, then selecting the TIF 2000A from the pick list of
key panels. The TIF 2000A operates much the same way as
a key panel, except that the “keys” are really the DTMF
buttons on the users telephone.
Auto Answer Mode
To use the TIF 2000 in auto answer mode, you must first
enable auto answer mode on the rear panel DIP switch
bank, switch 1.You may also wish to enable Password
Required, switch 3. In addition, you may select the number
of rings before the unit answers (internal DIP switch bank
#2), and the actual password (internal DIP switch bank #3).
When the caller dials into the TIF 2000A, they will hear the
line ring, then the unit will answer, and beep to request the
password (if password required is enabled). The user then
must enter the password. The unit will beep once to confirm
a proper password. If the password is not correct, the unit
will beep twice to allow another try.
Once the password has been entered, the TIF 2000A will
establish communications on key #1 automatically. From
AZedit, this will be talk and listen keys #1. If for example
the user were a camera operator, it might be desirable to
program the camera PL as talk and listen on talk and listen
keys #1. If the caller were a reporter, you might program an
IFB on listen key #1, but no talk on talk key #1.
Keys 2 to 7 may also be programmed. To use the other keys
from the phone, just press the DTMF button for the key you
wish to use. For example, if key #1 was the camera PL, and
you have finished with the shot, you may press #1, which
will toggle off key 1. If master control were programmed on
key #2, you may then press 2 and call master control.
Likewise, you might have an IFB programmed on listen 3,
with no talk. If you press 3, you will hear the IFB. #4 could
have an IFB talk on it, to allow a caller to speak on an lFB
circuit.
Each DTMF button acts as if it were a push on/push off
switch. When programming in AZedit, just program the
same key number as the number the user is going to press
on the telephone to speak.
Talk keys 8 to 15 have a special purpose. If you are not
using auto answer mode, but have set up the TIF 2000A to
be manually answered, talk keys 8 to 15 will be pro-
grammed for the keypanels which are to receive the ring
signal. They may also be toggled on and off from the phone
by DTMF 8, so they may be used in auto answer mode as
well.You may program only key 8, in which case it will
behave the same as keys 1-7.You may also program
additional keypanels, PLs, IFBs, etc on keys 9-15, and they
will be activated simultaneously by the 8 button on the
phone.
Manual Answer Mode
In manual answer mode, the line will ring until it is an-
swered from a keypanel. In general, you must designate
panels which are to receive the ring, so they can answer the
line. When a line is manually answered, the caller does not
have to enter a password, even if the password required
switch is turned on.You may mix modes by enabling auto
answer, but setting the ring count for 8 rings. If no user has
answered the call by 8 rings, the TIF 2000A will then
automatically answer the call, and if password required is
also enabled, the call will be screened by requiring a
password.
To use manual answer mode, you may choose to program
keys 1 to 7 as above if you wish. When the phone is
manually answered, key one will not be automatically
activated, but the caller may activate any of the keys if he
wishes.
You must also designate the panels which are going to ring
when the line rings. Program these panels on keys 8 to 15,
using both Ll and L2 if you have more than 8. It is generally
not necessary to program the listen keys on these positions.
When the line rings, the TIF 2000A will “call” these panels
when the line is ringing. When the line rings, the TIF 2000A
generates a ringer noise which is then transmitted to these
panels. The panels will display the TIF 2000A’s alpha
numeric in the incoming call window (CWW), and if a talk
key has already been programmed on the panel, its alpha
numeric will flash rapidly.
UsingTheTIF 2000A FromThe Telephone
The TIF 2000A will behave differently depending on how it
is programmed. It is up to the operator who programs the

13
TIF 2000A to convey to the user what to expect. If the user
is not familiar with the operation of the TIF 2000A, it is best
keep the operation as simple as possible, until they are
familiar with its operation. For this reason, it is suggested
that you not use password required unless you have had
problems with nuisance calls in the past. If the TIF 2000A
field user only requires one service, it is best to program
that service on key 1, enable auto answer, and disable
password required. The telephone user will then only have
to dial the proper phone number to use the interface. As they
become more familiar with its operation, you can then begin
to offer more options to the users, or begin to require a
password.
In general, it is very easy to use if the user has knows what
to expect. When calling in, if the unit is in auto answer
mode, it will answer the call after the number of rings which
have been selected. If password required is not enabled, the
unit will indicate it is ready with a single beep. If password
required is enabled, the TIF 2000A will prompt for a
password with 2 beeps. The user will enter the password,
and the unit will either beep once if the password was
correct, or twice if it was wrong. The user is allowed 3
attempts to enter the password, after which the TIF 2000A
will disconnect. In the event a user calls the TIF 2000A
when the intercom system is either turned off or absent, the
TIF 2000A will answer and prompt with 3 beeps.
Once the password is entered, the TIF 2000A will enable
talk and listen on key 1. This should be programmed ahead
of time to whatever communications the caller generally
needs first. If it is not desirable for the caller to be able to
talk at this point, then only the listen key for key 1 should
be programmed.
The caller may then either continue to use key 1, or they
may select other keys with their DTMF pad. They may turn
off key 1 by pressing DTMF 1, or may continue to just add
other keys. At any time, the caller may turn off all keys
without hanging up by pressing 0. When the call is com-
plete, the caller should enter *#, which will cause the
TIF 2000A to disconnect. This is more reliable than waiting
for the phone system to pass the disconnect information to
the TIF 2000A.
DTMF Codes
Once programmed, the TIF 2000A may be operated via the
DTMF keypad on the telephone. The DTMF keys have the
following functions:
Normal Mode:
1 thru 7 Toggle ON and OFF talk and listen #1 to #7.
Note: Initially, #1 will be enabled if the unit auto answered
the line.
8 Toggle ON and OFF talk and listen to the panels which
ring when the line is ringing. This allows the caller to
“recall” the panels without having to hang up and redial.
Toggling this on will allow the callers voice to be heard
from all the panels which normally ring.
9 Enters programming mode, to reassign keys.
0 Turn off all talk and listen keys. Since 1-8 are toggles, it
is possible to forget which keys are ON and which are
OFF. In this case, just press 0 to turn then all off, and
start over.
*1 thru *7 Toggle on and off listen 1-7. By pressing
* before the key, you only change the listen. This allows
you to listen to a circuit without talking to it, or to talk to a
circuit without listening to it.
Note:You will automatically listen and talk to #1 if the
TIF 2000A auto answered the line.
*8 Toggle ON and OFF listen for 8-15.
*# Disconnect. This will cause the TIF 2000A to hang
up. It is a good idea to do this before you hang up, as many
phone systems take a long time to signal that the far end has
hung up.
Programming Mode:
You may reprogram the talk and listen assignments on 1-7,
just as you can on a keypanel (if they are not restricted via
AZedit). Note that the sequences are the same as the
sequence you would use from a keypanel, except that you
must first enter programming mode by pressing 9.
Note: The use of programming mode is discouraged due to
a lack of feedback to the user to verify a programming
sequence has worked as intended.

TELEPHONE INTERFACE REQUIREMENTS FORM
October 2004
The Telex TIF 2000A Digital Hybrid Telephone Line Interface has been designed to respond to ringing for auto-answer and
to respond to a number of conditions to detect hang-up. These conditions are (in the standard product) based upon the
telephone systems of the US and other select countries. PBX (private branch exchange) systems in the US and other coun-
tries may have ringing and hang-up characteristics which differ from the design parameters used in the TIF 2000A. Public
telephone systems in countries other than those currently supported by Telex may have ringing and hang-up characteristics
which differ from the design parameters used in the TIF 2000A. Additionally, some countries require governmental approval
for connection of the TIF 2000A to the public telephone system. Telex handles these requirements on a case by case basis
and may require a one-time engineering fee to adapt the TIF 2000A for a specific telephone system or to obtain governmen-
tal approval. Additionally, Telex may require the customer to initiate the government approval process of the TIF 2000A for
their particular telephone system.
Here is a form which can be used to obtain the required specific technical information.
