Operation at ISDN point-to-point and multipoint interface
The i-modul ISDN HUT V4 can be operated at ISDN point-to-point
interfaces as well as at multipoint interfaces.
Different transfer protocols
The i-modul ISDN HUT V4 supports different transfer protocols, like
e.g. X.75, V.110 and HDLC (for PPP connections).
Data Buffering for Serial Transmission
The i-modul ISDN HUT V4 provides send and receive buffers to adjust
the i-modul ISDN HUT V4 to the data processing speed of the
application.
Hardware and software data flow control
The i-modul ISDN HUT V4 can interrupt the data flow of the
application via the control lines of the serial interface, if the buffers of
the i-modul ISDN HUT V4 exceed a certain level. An application can
also prompt the i-modul ISDN HUT V4 via a control line to interrupt
the data flow. As an alternative, the i-modul ISDN HUT V4 can control
the data flow via XOFF/XON characters in the data stream.

The i-modul ISDN HUT V4 can be set to accept only calls from phone
numbers that were previously stored.
Security Callback
The called i-modul ISDN HUT V4 can initiate an automatic call to a
predefined number, if a specified caller could be identified using CLIP.
Automatic call
The i-modul ISDN HUT V4 can initiate an automatic call either
depending on the DTR signal or independent of a status line.
Control outputs, controllable locally and remote
The i-modul ISDN HUT V4 has two potential-free control outputs,
which can be used to switch other functions in an application.

i-modul ISDN HUT V4 Operating Principle
5 Operating Principle
This chapter describes the basic procedures to operate and configure an i-modul
ISDN HUT V4. In general, the i-modul ISDN HUT V4 is configured and operated via
AT commands. You can enter these commands yourself with the help of a terminal
program and the AT command reference.
5.1 Operation with the Terminal Program
In general, any terminal program can be used. We recommend the program
TeraTerm by T. Teranishi under Windows. It is available free of cost on the
Internet at http://hp.vector.co.jp/authors/VA002416/teraterm.html. You can
use the program "minicom" if you work in a Linux environment.
Caution!
Damage of the serial interface!
A possible direct connection of the serial interface of the i-
modul ISDN HUT V4 with a typical RS232 interface of a PC
overloads components of the module due to the higher
voltage levels.
Use an RS232 level converter (e.g. MAX232) to adjust both
interface types correctly.
Configuring and operating the i-modul ISDN HUT V4 with a terminal program
How to configure and operate the i-modul ISDN HUT V4 with a terminal
program.
The i-modul ISDN HUT V4 is connected to the PC and supplied with power.
A terminal program is installed on the PC.
1. Start your terminal program.
2. Select the serial port, to which your i-modul ISDN HUT V4 is
connected.
COM1 under Windows corresponds to /dev/ttyS0 under Linux.
3. Type the character string AT into the terminal program. Complete the
entry by pressing the Enter key.
Each command input starts with AT and is completed with the Enter
key.
The

15
Operating Principle i-modul ISDN HUT V4
If the i-modul ISDN HUT V4 does not respond, this may have three
probable reasons:
a) the i-modul ISDN HUT V4 is switched off or
b) the i-modul ISDN HUT V4 is not in configuration mode or
c) the i-modul ISDN HUT V4 is connected to another serial port. Check
it and repeat step 3.
4. Configure the i-modul ISDN HUT V4 using AT commands.
A reference of the AT commands can be found in the chapter "AT
Command Reference".
5. Save your entries with AT&W.
Not all configurations at the i-modul ISDN HUT V4 need to be saved
actively by entering AT&W. Some settings are automatically saved
immediately. We still recommend sending the command AT&W to the i-
modul ISDN HUT V4 as your last configuration step to ensure that all
settings are stored safely and are available for the next restart.

i-modul ISDN HUT V4 Functions
6 Functions
6.1 Establishing or Accepting a Data Connection
The i-modul ISDN HUT V4 can call another ISDN TA (ISDN Terminal Adapter) via
the phone line and establish a data connection. After dialling a phone number, the
i-modul ISDN HUT V4 synchronises with the called TA and opens a data
connection. All incoming characters are transmitted to the other (called) TA during
the active data connection. Therefore, AT commands are not processed during a
connection. The i-modul ISDN HUT V4 must be changed to command mode again
using an "Escape sequence" that it processes AT commands again during an active
connection. Then, the local i-modul ISDN HUT V4 processes the entered characters
as AT commands and does not transmit them to the remote terminal.
The i-modul ISDN HUT V4 can accept an incoming connection in the same way.
For this, the "application" or the PC with the terminal program must support the
hardware data flow control at the serial interface, otherwise, the i-modul ISDN HUT
V4 does not accept the incoming connection. In this case, the hardware data flow
control must be disabled in the i-modul ISDN HUT V4 that a connection is accepted
regardless of the status of the application. The i-modul ISDN HUT V4 answers after
the configured number of ring tones and opens a connection.
This hardware data flow control is activated by default.
Configuration with AT commands
In order to establish a data
connection with the i-modul ISDN
HUT V4, use the command
Replace <number> with the phone
number of the remote terminal.
ATD<number>
In order to configure the data
connection protocol, use the
command
Refer to the AT command
reference for protocol details.
ATB
In order to configure the data
connection protocol, use the
alternative command

i-modul ISDN HUT V4 Functions
6.2 Querying the Alarm Inputs
The i-modul ISDN HUT V4 provides two digital inputs, which trigger an alarm
condition when connecting to ground. The status of these alarm inputs can be
queried via AT command. The i-modul ISDN HUT V4 can send a message in case
of an alarm. This message can be sent via data connection, as SMS or as e-mail via
a service provider. The i-modul ISDN HUT V4 evaluates a connection of the input to
ground as alarm. If no positive edge is counted at least 4 seconds after the
negative edge, an alarm will be processed. A pause of at least 5 seconds is
necessary after resetting the input before a new alarm can be triggered.
Figure 5: Pulse evaluation
Configuration with AT commands
In order to query the conditions
of the alarm inputs, use the
command
AT*I
The reply has the form <input1>, <input2>
The value "1" indicates an open
input and the value "0" indicates
a closed input. The example on
the right indicates: input 1
closed, input 2 open.

Functions i-modul ISDN HUT V4
6.3 Automatic call
The automatic call allows to initiate a call to a phone number previously stored in
the i-modul ISDN HUT V4. There are three possibilities for initiating a call.
The call may be initiated by the DTR line of the serial interface or incoming data at
the serial interface. Additionally, the i-modul ISDN HUT V4 can try to call a number
immediately after switching it on.
The phone number for the automatic call is taken from the dialling table "catab". If
a connection could not be established successfully, the i-modul ISDN HUT V4 dials
the next number from the dialling list. If none of the target phone numbers from
the dialling list could be reached, the i-modul ISDN HUT V4 initiates an automatic
redial. You can change the maximum number of attempts as well as the duration of
the pause until the next call.
6.3.1 Configuring an Automatic Call
In order to configure an automatic call, change to the Configurator mode of the i-
modul ISDN HUT V4 and enter the target phone number first, then select the
trigger for the connection establishment and set the reset timer. The reset timer
determines the time from the reset of the i-modul ISDN HUT V4 until the change to
the "automatic call" mode. If an automatic call is enabled, you have the possibility
to send AT commands to the i-modul ISDN HUT V4 during this time. The i-modul
ISDN HUT V4 does not accept AT commands anymore after you have configured
and enabled the automatic call. The reason for this is that incoming data are
immediately transmitted to the called remote terminal. An established connection
is indicated by the i-modul ISDN HUT V4 by the "OH" LED and "DCD" LED on the
housing front.
The automatic call is disabled in default setting . The dialling table "catab" is empty.
Configuration with AT commands
To start the TA+Configurator, use the
command ATCONF
To configure or overwrite the target phone
number(s) of the remote terminal, use the
command
Replace <n> with values from 1 to 10 (3 for
FW < 1.027).
