3. Connecting the module
3.1 Connecting the power supply
The equipment is supplied with +12V DC voltage. The power supply can be connected to the
onboard terminals (+12V and GND) or to the power socket. Never connect power supply
both to the terminals and to the socket at the same time. Correct power connection is
indicated by lighting of the PWR LED.
3.2 Connecting the alarm control panel
The telephone line connecting the control panel and the ISDN module may be connected to
the onboard terminals (T-1 and R-1) or to the RJ-11 telephone socket. Never connect the
analog telephone line both to the terminals and to the socket at the same time.
If the module is used as an external digital modem by the CA-64 or INTEGRA alarm control
panel, the two units should be additionally connected with the RS-232 cable. Length of the
RS-232 cable should not exceed 2.5 m. Never connect any equipment to both RS-232
sockets of the module at the same time. Configuration of the ISDN modem is carried out

by means of the AT commands. The ISDN modem automatically recognizes the RS-232
speed, the following speeds being supported: 4800Bps, 9600Bps, 19200Bps.
Fig. 2. Connection of the RS-232 ports of control panel and ISDN module.
The ISDN module is provided with a feature ensuring priority to the control panel outgoing
connections. To enable the control panel to make a connection, the other telephone lines
may be cut off.
The module factory settings with regard to cutting off the telephone lines ($C0) are based on
the assumption that the ISDN module works in the point-to-multipoint configuration ($M1)
(see section "Connecting the module to ISDN network"), and that the signal is connected to
the ISDN module from the control panel. It is recommended that the signal be connected
from the control panel OC output (signal polarization: active status 0V; the output
programmed as alarm one) to the INP and COM terminals of the ISDN module. With such
settings the ISDN module will cut off the ISDN line from the other devices only when the
control panel intends to make an alarm call, but it is impossible due to the line being occupied
by other subscriber devices. When the ISDN line is busy, and the outgoing connection
initiated by the control panel is not an alarm call, the ISDN module will not cut off the line to
the other subscriber devices, but will be waiting until the line is available.
If the alarm signal cannot be supplied to the ISDN module, it is recommended that you
change the line cut-off default settings to $C1, or leave the factory settings ($C0) and shortcircuit the INP and COM terminals. Both the $C1 setting and shorting the INP and COM
terminals with the $C0 setting will result in recognizing each connection initiated by the
control panel as the alarm call, and if the line is busy, all the other subscriber devices will be
cut off .
Telephone communication will be restored on all lines if no repeated demand to access the
telephone line is made within 10 seconds after the control panel hangs up. However, if the
panel fails to transfer all the programmed codes and messages, i.e. if at least one of the
connections has not been established because of the receiver line busy status, the telephone
communication will only be restored on all lines within 60 seconds after the control panel
hangs up.
In the point-to-point configuration ($M0) (see section "Connecting the module to ISDN
network"), the outgoing call initiated by the control panel will always require that the line be

cut off from the other subscriber devices, therefore it is recommended in this configuration
that you use the ($C1) setting, or short-circuit the INP, COM terminals with the $C0 setting.
3.3 Connecting the module to ISDN network
Correct connection of the module to the ISDN network, as well as selection of appropriate
settings, depend on the ISDN network configuration, the user is offered by the provider of
telecommunication services. There are two ISDN network configurations available on the
market, namely:
− point-to-multipoint configuration (usually offered to an individual customer),
− point-to-point configuration (often used by corporate customers, because of the possibility
to connect PABX equipment).
Prior to starting installation, you should determine the ISDN network configuration. The
SATEL ISDN module is programmed by default for operation in the point-to-multipoint
configuration. For the point-to-point configuration, it is necessary to program new module
settings by means of AT commands and save the settings.
3.3.1 Preparation for work in point-to-multipoint configuration
A characteristic feature of the point-to-multipoint configuration ($M1) is the possibility of
connecting many devices directly to the NT network termination module. When connecting
the ISDN module, you must take into account the maximum number of devices supported by
the NT network termination module (usually 8). The ISDN module is recognized as one of the
digital devices. The specific character of ISDN network in the discussed configuration allows
for simultaneously making up to two connections on the B-channels. This means that the
network can be simultaneously used by not more than 2 devices (e.g. 2 telephones or a
telephone and fax). However, it can happen that both B-channels are used by one device
(e.g. a modem connecting to the internet). In order to ensure tamper protection and correct
interaction between the ISDN network, ISDN module, control panel, and the other subscriber
devices, it is necessary to observe the essential principle of installation: the ISDN module
must be the first device connected to the S/T interface of the NT network termination module.
All the other subscriber devices (both analog and digital) must be connected by means of the
ISDN module and, if necessary, ISDN separator.
Use the RJ-45 socket marked as the ISDN-IN to connect the module to the digital telephone
network. Connect the equipment to the S/T interface of the network termination according to
the network termination manufacturer's directions. Length of the cable connecting the
ISDN module with the network termination should not exceed 2.5 m. Active state of the
S/T interface of the network termination is indicated by lighting of the LNK LED.
Probably the most frequently encountered case is connection by means of the ISDN module
to the ISDN network of the control panel and one digital subscriber device and/or one analog
subscriber device. Diagram of such an installation is shown in Fig. 3.

subscriber device.
Where the ISDN module is used as an adapter which enables the control panel to be
connected to the ISDN network, the digital equipment should be connected to the ISDN
module socket marked as the ISDN-OUT. Such a connection protects the alarm system
against tampering.
Connecting a larger number of subscriber devices is more complicated. In such a case, an
ISDN separator must be used.

6 – RJ-11 connector, designated ANALOG2 OUT – output, analog telephone line 2;
7 – RJ-11 connector, designated ANALOG2 IN – input, analog telephone line 2;
8 – relays.
The ISDN separator is to be connected to the ISDN module with two wires: connect the OUT
terminal of the ISDN module to the IN terminal of the separator, and connect together the
SEP terminals of both devices. The separator is fitted with a pair of RJ-45 ports for
connecting one additional digital subscriber device, and two pairs of RJ-11 ports for
connecting two additional analog subscriber devices. As the commercially available NT
modules have, usually, two connectors for digital devices (so-called S/T interface) and two
connectors for analog devices (so-called a/b interface), the design of ISDN module and the use
of SATEL ISDN separator ensure a tamper protection through exercising control of all the four
lines made available by the NT network termination module. An example of connecting
additional subscriber devices via the ISDN separator is shown in Fig. 5.

3.3.2 Preparation for work in point-to-point configuration
The point-to-point configuration is mainly offered to corporate customers. It enables just one
device, usually a private exchange, to be connected to the NT network termination module. If
it is required to use the ISDN module in this configuration, you should change the ISDN
module settings, using AT commands, for operation in the point-to-point configuration ($M0).
In this case, the installation diagram will look as shown in Fig. 6.
It is assumed by default that another subscriber device, e.g. a private exchange is connected
to the ISDN module ISDN-OUT socket ($D1). For testing purposes or when the ISDN module
is the only digital device connected to the NT network termination module, you should
change the default settings related to presence of other devices to $D0.

5. Modification of ISDN Module Settings with AT Commands
The RS-232 port enables the ISDN module to be connected to the computer, thus making it
possible to modify the equipment settings by means of the AT commands (with Terminal type
program – as is the case in the traditional modem). Having entered the command, confirm it
by pressing the ENTER key.
The device settings are divided into 3 groups:
− ACTIVE SETTINGS – active settings, currently used by the ISDN module,
− USER PROFILE SETTINGS – user settings, defined by the user and stored in nonvolatile memory,
− FACTORY SETTINGS – factory settings.
By entering the AT&V command, you can see all the setting profiles.
Fig. 7. Window of the Hyper-Terminal program, showing the ISDN module settings.
After power-up, the user settings are loaded into the active profile. At the first start of the
ISDN module, the active, user, and factory settings are identical. The active settings can be
modified with the use of AT commands. For the modifications to be permanent, the new
settings must be saved in the non-volatile memory (user profile) by means of the AT&W
command. Loading the factory settings into the active profile is made possible by the AT&F
command. In order to load the user settings into the active profile, enter the ATZ or ATZ0
command.
