Function Overview i-modul ISDN HIX V4

3 Function Overview

The i-modul ISDN HIX V4 provides you with the following functions:

 Operation at ISDN point-to-point and multipoint interface

The i-modul ISDN HIX V4 can be operated at ISDN point-to-point

interfaces as well as at multipoint interfaces.

 Different transfer protocols

The i-modul ISDN HIX 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 HIX V4 provides send and receive buffers to adjust

the i-modul ISDN HIX V4 to the data processing speed of the

application.

 Hardware and software data flow control

The i-modul ISDN HIX 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 HIX V4 exceed a certain level. An application can

also prompt the i-modul ISDN HIX V4 via a control line to interrupt the

data flow. As an alternative, the i-modul ISDN HIX V4 can control the

data flow via XOFF/XON characters in the data stream.

 Automatic call

The i-modul ISDN HIX 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 HIX V4 has two potential-free control outputs,

which can be used to switch other functions in an application.

 Remote configuration

The i-modul ISDN HIX V4 can be configured remotely using another

INSYS ISDN device and a terminal program.

 Voice functionality

The voice functionality allows to establish voice connections with

other phones using a connected phone receiver for example. This

provides an easy communication with the service personnel at the

site. Moreover, the module also allows to accept voice calls.

Operating Principle i-modul ISDN HIX V4

5 Operating Principle

This chapter describes the basic procedures to operate and configure an i-modul

ISDN HIX V4. In general, the i-modul ISDN HIX 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 HIX 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 HIX V4 with a terminal program

How to configure and operate the i-modul ISDN HIX V4 with a terminal

program.

 The i-modul ISDN HIX 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 HIX 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.

Functions i-modul ISDN HIX V4

6 Functions

6.1 Establishing or Accepting a Data Connection

The i-modul ISDN HIX 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 HIX 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 HIX 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 HIX V4 processes the entered characters

as AT commands and does not transmit them to the remote terminal.

The i-modul ISDN HIX 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 HIX

V4 does not accept the incoming connection. In this case, the hardware data flow

control must be disabled in the i-modul ISDN HIX V4 that a connection is accepted

regardless of the status of the application. The i-modul ISDN HIX 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

connection with the i-modul ISDN

HIX V4, use the command

Functions i-modul ISDN HIX V4

6.1 Querying the Alarm Inputs

The i-modul ISDN HIX V4 provides two digital inputs, which trigger an alarm

condition when connecting to ground. The status of these alarm inputs can be

queried via the respective S register using an AT command. The i-modul ISDN HIX

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 HIX 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 7: Pulse evaluation

Configuration with AT commands

In order to query the condition of

alarm input 1, use the command ATS17?

In order to query the condition of

alarm input 2, use the command ATS18?

a closed input. The response on
