1 SAFETY
The unit described is designed against the latest technical parameters and
complies with all national and international safety requirements. It operates
with a high level of operational safety resulting from long development experi-
ence and stringent quality control in our company.
In normal operation this equipment is safe.
There are, however, some potential sources of danger that cannot be com-
pletely eliminated.
This Operator Manual therefore contains basic safety instructions that must be
observed during system configuration and operation. This Operator Manual
must be read before the system is used and the current version of the docu-
ment must always be kept close to the equipment.
All safety instructions have a uniform appearance. This appearance is de-
scribed in detail in CHAP. 1.2 .
1.1 General Safety Requirements
In order to keep the technically unavoidable residual risk to a minimum, it is
imperative to observe the following rules:
•Transport, storage and operation of the unit/system must be under the
permissible conditions only.
•Installation, configuration and disassembly must be carried out only by ex-
pert personnel and with reference to the respective documentation.
•The system must be operated by expert and authorised users only.
•The system must not be operated unless it is in perfect working order.
•Any conversions or changes to the system or parts of the system (includ-
ing the software) must be carried out by qualified personnel from our com-
pany or by expert personnel authorised by our company.
All changes carried out by other persons lead to a complete exemption
from liability.
•The removal or disabling of safety facilities, the clearing of faults and er-
rors, and the maintenance of the equipment must be carried out by spe-
cially qualified personnel only.
•Non-system software is used at one´s own risk. The use/installation of
non-system software can adversely affect the normal functioning of the
system software.
•Only use tested and virus-free data carriers!
1.2 Appearance of the safety instructions
All safety instructions include a signal word that classifies the danger and a
text block that contains descriptions of the type and cause of the danger, the
consequences of ignoring the safety instruction and the measures that can be

PAGE 1-8 RTS ISDN 2002 System
taken to minimise the danger. In some safety instructions, a warning symbol is
placed underneath the signal word (see also CHAP. 1.2.2):

2 INTRODUCTION
The RTS ISDN 2002 System incorporates two Audio codecs according to
G.711 and G.722 coding algorithms for bi-directional communication. The
coding delay of the 7-kHz G.722 coding algorithm is less than 10ms. The two
Audio codecs included in the system can be configured as 3.1-kHz (G.711) or
7-kHz (G.722) Audio codecs. Each coded Audio signal occupies a single
ISDN B channel (64-kbit/s channel). Therefore both codecs are using 2 B
channels of the S
o
interface. In the 7-kHz coding mode also a data signal can
be transmitted. Two different types of data interfaces are available. In the
G.711 Telephone mode the system detects the DTMF tones received from a
standard Telephone set and converts the tones into the Telex protocol for the
control of Matrix units. The system can be configured as 2 x G.711 Audio
codecs with two separate Audio interfaces but one common RS485 data in-
terface. In the 7-kHz (G.722) Audio codec mode a RS232 and a RS485 data
channel are available. These data channels can be used for the interconnec-
tion of a Matrix unit to a Trunkmaster system.

RTS ISDN 2002 System PAGE 3-11
3 FUNCTIONALITY
After the connection to the partner system is established audio and data
transmission starts immediately. Is the 7-kHz coding standard on both sys-
tems configured both systems run in the 7-kHz mode.
For remote control of Telex Intercom equipment four operating modes are
available.
Mode 1 supports a communication with a standard telephone set and trans-
mits the received DTMF tones to the Telex Intercom equipment for remote
control.
In Mode 2 a 7-kHz connection can be established and a RS485 data channel
can be used for remote control of a Matrix by key panels.
In Mode 3 two Matrix units can be interconnected.
In Mode 4 Matrix units are interconnected and audio signals can be routed
controlled by a Trunkmaster unit. For this purpose the data interfaces of the
Matrix units are connected over the RTS ISDN 2002 System to the Trunk-
master system.

4 SYSTEM DESCRIPTION
4.1 Mechanical Design
The RTS ISDN 2002 System is a 19” unit with 1 unit in high with the dimen-
sions (W x H x D) 449 mm x 44 mm x 275 mm. RTS ISDN 2002 System can
be installed as a table top unit or in 19" racks. Sufficient ventilation is ensured
by ventilation holes located on the top and bottom of the housing.
Figure 1 shows the rear view of the RTS ISDN 2002 System.
Figure 1: Rear view of RTS ISDN 2002 System
The RTS ISDN 2002 System is powered by an integrated power supply unit.
with AC voltages between 90V and 253V (nominal voltage range 230-240V).
The mains frequency can also vary between 50 and 60 Hz. The maximum
power consumption is approx. 20 W. The equipment also has 6 LEDs on the
front panel which are used for status indication of the system. The configura-
tion of the system will be done by a PC via the control Interface (RS232) at the
rear side of the unit.
4.2 Functionality
The RTS ISDN 2002 System provides 4 operating modes
4.2.1 Mode 1: Telephone to key panel

RTS ISDN 2002 System PAGE 4-13
In this operating mode two Telephone sets can dial a RTS ISDN 2002 system.
Via the DTMF tones of the telephones the key panels can remotely be con-
trolled. The system converts the received DTMF tones into the Telex
protocol.
4.2.2 Mode 2: Key panel to Matrix
At both sides RTS ISDN 2002 products are installed. The RS485 commands
are transmitted between Matrix and remote key panels by the RTS ISDN 2002
system. The Audio transmission quality is 7-kHz
4.2.3 Mode 3: Matrix to Matrix
Matrix units are interconnected by 7-kHz transmission channels. Only Audio
signals are transmitted.
4.2.4 Mode 4: Matrix to Matrix with Trunkmaster
In addition to Mode 3 also one RS232 and one RS485 data channel from the
remote Matrix can be transmitted to the Trunkmaster.

5 PUTTING THE SYSTEM INTO OPERATION
5.1 Mounting
With its dimensions (W x H x D) of 449 mm x 44 mm x 275 mm the RTS ISDN
2002 System can be operated as a table-top device or, be inserted into 19"
racks.
The dimensions given above are valid for the table-top version with no feet. If
the RTS ISDN 2002 System is to be inserted into a rack, it should be remem-
bered that the bending radius of the cables should always be greater than the
minimum allowed value.
If the RTS ISDN 2002 System is installed in a rack, it should also be ensured
that sufficient ventilation is provided. It is recommended that at least 1 cm
space is left next to the openings. As rule, the ambient temperature should not
lie outside the range +5°C to +40°C. These limits are of particular importance
if the system is inserted in a rack.
During operation, the humidity must lie between 5% and 85%.
NOTICE
!
Incorrect ambient temperature and humidity can lead
to equipment failure
Operation of the unit outside the above limits invali-
dates the warranty.
The RTS ISDN 2002 System must therefore be oper-
ated within the specified limits.
5.2 Connection to the mains voltage
The integrated power supply unit of the RTS ISDN 2002 System can be oper-
ated with a voltage (mains) between 90 V and 253 V. The mains frequency
can vary between 50 Hz and 60 Hz. The power consumption is a maximum of
approx. 20 W.
After putting the unit into operation, the “POWER” LED should light up. An in-
ternal reset is then triggered. This is indicated by a blinking “ALARM” LED.
After approximately twenty seconds, the unit is operational and the red
"Alarm" LED should stop blinking.
5.3 Signalling LEDs
There are six LEDs for signalling on the RTS ISDN 2002 System
(see Figure 2):
•Power: green
Lights up when system is powered.
•Alarm: red
Lights up if a fault has occurred in the unit.

RTS ISDN 2002 System PAGE 5-15
•DATA CALL 1 : green
Is slow flashing if an outgoing call is initiated
Is fast flashing if an incoming call is detected
Lights up if a 7-kHz Audio connection is established for Codec 1
•DATA CALL 2 : green

Is fast flashing if an incoming call is detected
Lights up if a 7-kHz Audio connection is established for Codec 2
•PHONE CALL 1 : orange
Is slow flashing if an outgoing call is initiated

Lights up if a 3.1-kHz Audio connection is established for Codec 1
•PHONE CALL 2 : orange
Is slow flashing if an outgoing call is initiated
Is fast flashing if an incoming call is detected
Lights up if a 3.1-kHz Audio connection is established for Codec 2
