12 Functions

12.1 Select country-spezific presets

Note

Loss of saved settings.

Changing the country code will reset all stored settings
in the INSYS Modem 56k Small INT 2.0 to factory de­faults (except the country code setting).

Download (or make notes of) the settings of your INSYS
Modem 56k Small INT 2.0 before you change the country
specific preset.

The INSYS Modem 56k Small INT 2.0 holds a range of presets, which allow you to adjust
the device to the standards and requirements of the local telephone network. The firm­ware of the INSYS Modem 56k Small INT 2.0 contains the presets for the so called „stan­dard countries“. You find a list of contries and the corresponding country codes in the
section „Country Codes“.

To select presets for countries, which are not in the listed among the standard countries,
you have to change the firmware of the INSYS Modem 56k Small INT 2.0 (See chapter
„Maintenance“).

The default setting is „Europe“ with the country code „FD“.

Configuration with HSComm

Choose the preset for the country where you’re going to use the INSYS Mo­dem 56k Small INT 2.0 in the software HSComm on the tab „Modem“ in the
panel International Settings (Page 27, Figure 5: HSComm Modem - Tab Mo­dem, Position 14).

Configuration with AT commands

To choose the preset for the country where
the the INSYS Modem 56k Small INT 2.0 is de­ployed, use the command:

12.2 Automatic Baud Rate Detection

12.2.1 Serial Connection

The automatic baud rate detection enables a continuous automatic adjustment of all
parameters (baud rate, data format) of the serial interface at the INSYS Modem 56k
Small INT 2.0. The device will detect during the operation, which baud rate and which
data format is applied to the serial interface. After a restart, the INSYS Modem 56k Small
INT 2.0 will restore the last working interface configuration. With each incoming AT
command (according to the character string "AT"), the parameters for the interface of
the INSYS Modem 56k Small INT 2.0 will be checked and adjusted, if necessary. This is the
reason why the baud rate can not be stored with the command AT&W, as the INSYS Mo­dem 56k Small INT 2.0 will immediately adjust its interface to the current parameters of
the currently established serial connection.

The function is active as default.

Configuration with HSComm

A configuration using HSComm is not possible, because the automatic baud
rate detection will re-adjust the baud rate of the serial interface at the INSYS
Modem 56k Small INT 2.0 immediately after each further "AT". As the soft­ware sends several commands, entering an AT command to temporarily
change the baud rate in the field "Initialization string" will at best be ineffec­tive. It can also result in errors during the transmission of the settings from
the software to the INSYS Modem 56k Small INT 2.0.

Configuration with AT commands

To set the baud rates temporarily (until the
next "AT"), enter one of the following baud
rates for <n>:
300, 600, 1200, 2400, 4800, 9600, 14400,
19200, 28800, 38400, 57600 or 115200 bps.

This setting can not be stored.

The INSYS Modem 56k Small INT 2.0 must be configured with the baud rate,
which is used to operate the application at a later time, as the INSYS Modem
56k Small INT 2.0 will always use the last known functioning configuration of
its interface.

INSYS Modem 56k Small INT 2.0 Functions

12.2.2 Phone connection

The automatic negotiation of the baud rate and the modulation standard enables the
INSYS Modem 56k Small INT 2.0 to negotiate the largest possible connection speed to the
remote terminal while the connection is established. The speed depends on the settings
and the abilities of the modem at the remote terminal. Via the modulation standard, the
connection speed can be set through the phone line. If nothing is defined, the INSYS Mo­dem 56k Small INT 2.0 will automatically try to determine the optimum connection pa­rameters.

The function is active as default.

Configuration with HSComm

A direct configuration with the HSComm is not intended. The AT command to
define a fixed baud rate can be sent to the INSYS Modem 56k Small INT 2.0 via
the entry field "Initialization string" (Page 27, Figure 5: HSComm Modem - Tab
Modem, Position 13).

Configuration with AT commands

To configure the modulation standard and
thus the connection speed, use the command:

AT+MS=<modulation>

Please find the possible parameters for this command in the Chapter "AT
Command reference".

To display the current settings:

AT+MS?

For a list of possible parameter of the com­mand, enter:

AT+MS=?

12.3 Data Buffer for Serial Data Transmission

The INSYS Modem 56k Small INT 2.0 has send and receive buffers. These buffers prevent
the loss of data, in case the application or the remote terminal can not receive data at
this time. The data buffer can be deactivated together with the error correction (bit di­rect mode). When the buffer is activated, the data flow control should be active to avoid
a buffer overflow in the INSYS Modem 56k Small INT 2.0. If the buffer flows over, the IN­SYS Modem 56k Small INT 2.0 will perform a reset. Operation without a buffer and error
correction is only useful for special character framings.

The function is active as default.

Configuration with HSComm

Select the type of error correction on the tab Modem in the panel "Phone in­terface" (Page 27, Figure 5: HSComm Modem - Tab Modem, Position 25). Buff­ering is active for all options except the option "unbuffered, bit direct". To de­activate the buffer (and simultaneously the error correction), select "un­buffered, bit direct".

Functions INSYS Modem 56k Small INT 2.0

32

Configuration with AT commands

To deactivate the error correction as well as
the buffer in the INSYS Modem 56k Small INT

2.0 for applications with special data format,
use the command:

AT\N1

To deactivate only the error correction, use the
command:

AT\N0

12.4 Bit Direct Mode

For special applications, the buffering of the INSYS Modem 56k Small INT 2.0 can be de-
activated using the setting "unbuffered, bit direct". All data is forwarded without buffer­ing and further influence of the INSYS Modem 56k Small INT 2.0. This applies especially
to the parity and stop bits. The error correction and the data compression are in this case
switched off as well. If the INSYS Modem 56k Small INT 2.0 is operated in this mode, not
all functions will be available. The remote configuration and all functions for which a
password is required, will no longer be available. This mode should only be used for spe-

cial character framings.

Configuration with HSComm

Select the type of error correction on the tab Modem in the panel "Phone in­terface" (Page 27, Figure 5: HSComm Modem - Tab Modem, Position 25). Se­lect "unbuffered, bit direct" to switch to bit direct mode.

Configuration with AT commands

To deactivate the buffer of the INSYS Modem
56k Small INT 2.0 and to switch on the bit di­rect mode, use the command:

AT\N1

12.5 Data Flow Control (Handshake)

The data flow control ensures that the data transfer is interrupted as soon as the modem
buffer exceeds a certain level. Two data flow control options are available: Via the con­trol lines RTS and CTS, or via the control characters XON/XOFF which are inserted into
the data stream.

12.5.1 Hardware data flow control (RTS/CTS)

The hardware data flow control works in two directions. When the critical buffer level is
exceeded, the modem will set the CTS line to "low" and will thus indicate to the applica­tion to interrupt the dataflow. When the buffer is emptied sufficiently for the INSYS Mo­dem 56k Small INT 2.0 to be able to receive data again, the CTS line is set to "high". Re­versely, the application can also indicate to the INSYS Modem 56k Small INT 2.0 to inter­rupt the data flow. This is done via the RTS line. If it is set to "low", the modem will inter­rupt the data flow to the application. The application will set it to "high" to request data
from the INSYS Modem 56k Small INT 2.0.

INSYS Modem 56k Small INT 2.0 Functions

33

The data flow control with RTS/CTS behavior is active by default.

Configuration with HSComm

Select the type of data flow control or switch it off completely on the tab Mo­dem in the panel "Handshake" (Page 27, Figure 5: HSComm Modem - Tab Mo­dem, Position 26).

Configuration with AT commands

To switch the data flow control on and to set
the type to RTS/CTS, use:

AT&K3

To switch the data flow control off, use:

AT&K0

12.5.2 Software data flow control (XON/XOFF)

When the input buffer of the modem exceeds a certain fill state, the modem will insert
an XOFF character into the data stream to the application. This character will cause the
application to send no more data. It will depend on the according application software if
the XON/XOFF data flow control is supported.

After the input buffer of the modem is emptied so much that data can be received again,
the modem will send an XON character to the application. This character will cause the
application to send data to the modem again. Analogously, the application can insert
XON/XOFF characters into the data stream to switch the data flow on and off. The
XON/XOFF data flow control is only available when the transmitted data do not contain
the characters XON or XOFF, which usually appear only in actual ASCII texts (7 bit). When
binary data (programs, etc.) are transmitted, or in the XMODEM transmission protocol,
for example, occasionally appearing XON or XOFF characters would disturb the opera­tion.

Configuration with HSComm

Select the type of data flow control or switch it off completely on the tab Mo­dem in the panel "Handshake" (Page 27, Figure 5: HSComm Modem - Tab Mo­dem, Position 26).

Configuration with AT commands

To switch the data flow control on and to set
the type to XON/XOFF, use:

12.6 Error correction

The INSYS Modem 56k Small INT 2.0 masters the V.42 error correction protocol including
the Microcom Networking Protocol Levels 2/3/4 (MNP2, MNP3, MNP4) and the data
throughput optimization MNP10. The V.42 error correction includes the protocols LAPM
(Link Access Procedure for Modem) and MNP4. LAPM is the preferred error correction.
MNP 4 is supported to maintain the compatibility with other MNP modems. Both meth­ods determine frames to transfer net data and use CRC (Cyclic Redundancy Check) check
sums for error tests. In V.42, there is the option to have the modem identify if the partner
is a V.42 modem, a MNP modem, or a modem without error correction. The modem can
then autonomously adjust to the partner.

As default, the automatic selection of V.42LAPM or MNP4 or no correction is set.

Configuration with HSComm

Select the type of data flow control or switch it off completely on the tab Mo­dem in the panel "Error correction" (Page 27, Figure 5: HSComm Modem - Tab
Modem, Position 25).

Configuration with AT commands

To define the type of error correction, use the
command:

AT\N<n>

To set V.42LAP-M or MNP4 error correction
exclusively, use:

AT\N2

Use the following command for the INSYS
Modem 56k Small INT 2.0 to automatically
select V.42LAP-M, MNP4, or an error-corrected
connection:

AT\N3

To set V.42LAP-M error correction exclusively,
use:

AT\N4

For the buffered mode without error correc­tion, use:

AT\N0

12.7 Data Compression

The INSYS Modem 56k Small INT 2.0 supports various data compression types. During
the connection setup, it will automatically detect the type of data compression used by
the remote terminal, or it is set to a certain type of data compression. Data compression
is only available for error corrected connections. To be able to use data compression,
both sides (sender and recipient) must be able to at least recognize and support the
same data compression mode.

The default setting is the automatic selection of MNP5 and V42.bis and V.44 data com­pression (AT%C3).

12.8 Selective Call Acceptance

If the selective call acceptance is activated, the INSYS Modem 56k Small INT 2.0 will only
accept calls from previously defined callers. The INSYS Modem 56k Small INT 2.0 will
identify the caller via CLIP. This must, however, be supported by the network provider or
the phone system, where the modem is connected to. The list of phone numbers of the
INSYS Modem 56k Small INT 2.0 has 8 storage locations altogether (N0 to N7).

Configuration with HSComm

Direct configuration with the HSComm is not intended. This function can only
be configured via AT commands.

Configuration with AT commands

To activate the selective call acceptance, use
the command:

AT&A1

To switch the selective call acceptance off, use
the following command:

AT&A0

To display a complete list of stored phone
numbers for the selective call acceptance, use:

AT*N?

To delete a single storage location, overwrite
the storage location with an empty space after
the character "=".

AT*N<n>=

To delete the entire phone list for the selective
call acceptance:

AT*N99

To store the phone number <nr> in the stor-
age location <n> , use:

AT*N<n>=<nr>

The INSYS Modem 56k Small INT 2.0 checks the phone number sent via CLIP
for one of the stored numbers. The check starts on the "right", i.e. from the
end of the phone number submitted by CLIP. This makes it possible to recog­nize a phone number, although a prefix such as "+49" or "0049" was placed
before the number. Also, the number for the detection can be made variable
with the help of wild cards. The stored phone numbers may not include any
separators, such as dashes between prefix and phone number.

For example, to permit the numbers
[phone], 0941686920, 0049941686920
as callers, just store 941686920 at the location
number 1.

AT*N1=941686920

For each variable digit in the phone number,
an asterisk * can be entered.

To keep the last two digits variable, e.g. to al­low callers from extensions, use two (**) char­acters.

12.9 Sending messages via data connection, SMS or Fax

The INSYS Modem 56k Small INT 2.0 can send a message via SMS, data connection, or as
e-mail. The sending of messages can only be triggered via an AT command. By default,
three attempts are made to send a message.

Configuration with HSComm

To define the Type of connection for the message dispatch (mobile, modem,
fax), select the according type in the dropdown menu (Page 28, Figure 6:
HSComm Modem - Tab Alarm functions (pulse input active was selected), po­sition 11).

A dial character (e.g. "0") for the exchange in phone systems can be entered in
the entry field "Character for exchange" (Page 28, Figure 6: HSComm Modem ­Tab Alarm functions (pulse input active was selected), position 2).

To define a message for the according recipient, enter the message in the en­try field (Figure 6: HSComm Modem - Tab Alarm functions (pulse input active
was selected), position 6). Enter the phone number of the recipient with the
prefix (or the country prefix) into the field under "Phone number" (Page 28,
Figure 6: HSComm Modem - Tab Alarm functions (pulse input active was se­lected), position 8). Ensure that the phone number of an SMS service center
from the drop down menu "Service center number" (page 28, Figure 6:
HSComm Modem - Tab Alarm functions (pulse input active was selected), po­sition 8) is entered.

The number of attempts to send a message can be specified. Three attempts
are set by default. The number of dialing attempts can be increased in the
dropdown field (page 28, Figure 6: HSComm Modem - Tab Alarm functions
(pulse input active was selected), position 3).

It is also possible to send the message independent from the selection con­nection type to a fax device as well. Activate the check box "FAX group mes­sage" (page 28, Figure 6: HSComm Modem - Tab Alarm functions (pulse input
active was selected), position 7). Next to the check box, an entry field for the
recipient number is displayed. Enter the number of the fax device, to which
the message is to be sent in addition.

12.11 Switching on the Remote Configuration

The INSYS Modem 56k Small INT 2.0 can be configured remotely. It has a remote configu­ration mode. To configure the INSYS Modem 56k Small INT 2.0 remotely, a data connec­tion to the modem to be configured must be established. This can be performed by call­ing the INSYS Modem 56k Small INT 2.0 from any modem. After switching into the re­mote configuration mode, AT commands can be sent to configure the INSYS Modem 56k
Small INT 2.0.

To switch into the remote configuration mode, a data connection must be established
between the modems. A particular connection type is not mandatory. We recommend
using only error-corrected connections for the remote configuration to avoid AT com­mand transfer errors.

The remote configuration is active as default.

Configuration with HSComm

To enable the remote configuration, activate the checkbox "Automatic call ac­ceptance" (Page 27, Figure 5: HSComm Modem - Tab Modem, Position 15).

Select an error correction type (Page 27, Figure 5: HSComm Modem - Tab Mo­dem, Position 25). The remote access will not work in bi-directional mode.

You can define a password, which is queried after switching into the remote
configuration mode (Page 27, Figure 5: HSComm Modem - Tab Modem, Posi­tion 24).

Use the function Selective call acceptance to restrict the dial-in at the INSYS
Modem 56k Small INT 2.0 to certain phone numbers. The selective call accep­tance can only be configured via AT commands.

L Enter **** to re-initiate a remote configuration.

12.13 Access Control and Security Callback

To protect yourself from unauthorized access via the phone line, the modem may be pro­tected by a password. This password is used to establish a data connection, for security
callback and remote configuration. This means: If the access control is activated, the sys­tem will prompt you for a password before outgoing connections and when dialing into
the INSYS Modem 56k Small INT 2.0 for remote configuration. After successful authenti­cation, the function Security Callback will trigger a callback from the INSYS Modem 56k
Small INT 2.0 to a predefined number.

The factory default standard password is "QWERTY".

Configuration with HSComm

Under "Access Control" (Page 27, Figure 5: HSComm Modem - Tab Modem, Po­sition 24), you can determine, if you want to use access control with a pass­word, or if you want to perform a security callback. The password can also be
defined.

Enter the phone number, which the INSYS Modem 56k Small INT 2.0 calls as
response to an incoming call. To call only the caller identified by CLIP, just en­ter the letter "C" instead of a phone number.

the phone number to be called, use the com­mand:

AT&Z1=<YourNumber>

Please note: If you operate the INSYS Modem 56k Small INT 2.0 at a phone sys­tem, which will not provide an exchange after going off-hook, enter the char­acter for the exchange together with the phone number.

To activate the security callback and to call
back the caller identified by CLIP instead of a
special phone number, use the command:

AT&Z1=C

Please note that a phone system may make a callback impossible, if it requires
an exchange first. Some phone systems, however, can add the character for
the exchange to the CLIP which they send to the end device.

To store the command, use the command:

12.14 Idle Connection Control with Data Transmit Control

The Data Transmit Control (DTC) is a function of the INSYS Modem 56k Small INT 2.0
which monitors the data transmission in online mode. This function prevents the INSYS
Modem 56k Small INT 2.0 to stay online for an unlimited amount of time, although no
data is being transmitted anymore. The DTC function can define the time after which the
INSYS Modem 56k Small INT 2.0 will hang up as soon as there is no data transfer on the
phone line.

12.15 Priority Circuit for a Phone Connected in Series to the IN­SYS Modem 56k Small INT 2.0

The INSYS Modem 56k Small INT 2.0 may give a phone connected in series priority, to
make sure the modem functions interfere as little as possible with the usage of the
phone connection. TheINSYS Modem 56k Small INT 2.0 can determine on the basis of the
voltage in the line, if the phone line is used by a phone, if a phone in series is going off­hook or if the remote terminal of the INSYS Modem 56k Small INT 2.0 is terminating the
connection.

The functions of the priority circuit may be combined or used individually. The functions
can be selected and activated with the AT command AT-STE=<n>.

The following table provides the combination of functions with the according AT-STE
command.

The modem detects the status of the phone line at the voltage levels in the line. Option­ally, the voltages for the various line states can be set with the command AT-
TTE=U1,U2,U3. The voltages U1, U2 and U3 are by default set to functioning values and
need not be modified. The following illustration shows the voltage curve for the accord­ing line state and the appropriate AT command parameters.

Figure 7: Line states and voltages in the line

State Description

1 No connection has been established. The line is free.
2 A connection has been established. The telephone is off-hook and connected to a

remote terminal. The voltage in the line has dropped with the amount of U1. The
INSYS Modem 56k Small INT 2.0 can thus detect that the line is busy.

3 A connection has been established, but this time the INSYS Modem 56k Small INT

2.0 occupies the line and is connected to a remote terminal. If the telephone con­nected in series goes off-hook, the voltage will drop with the amount U2. The INSYS
Modem 56k Small INT 2.0 will detect that the phone has gone off-hook and will
terminate the connection.

4 The line is busy during a modem connection. After the remote terminal hangs up,

the INSYS Modem 56k Small INT 2.0 will detect through the short power spike U3
(the crackling noise in the line) that the remote terminal has hung up. This will set
the event code of the S registry 86 to 25 (remote terminal has hung up). This means
that the INSYS Modem 56k Small INT 2.0 will not keep the line busy for an unneces­sarily long period.
If phone systems are used which dampen the crackling noise or the short power
spike, it may occur that the system will not detect that the remote terminal has
hung up.

Configuration with AT commands

To use the desired functions of the priority
circuit, use:

AT-STE=<n>

To set the voltage level for the detection of the
line status, use:

U1 is the voltage difference in the phone line
between hung up state (free line) and the busy
line.

U2 is the voltage difference, which is gener­ated in the phone line when the INSYS Modem
56k Small INT 2.0 has already gone off-hook
and a telephone connected in series is going
off-hook.

U3 is the voltage difference in the phone line
between hung up state (free line) and the busy
line.

Command Description

ATD<n> Dial

The INSYS Modem 56k Small INT 2.0 goes off-hook and dials according to the dialing
string transmitted via the ATD command. After the dialing procedure, the INSYS Mo­dem 56k Small INT 2.0 attempts to establish a connection. If the ATD command was
performed without a dialing string, the INSYS Modem 56k Small INT 2.0 goes off-hook
and attempts to connect to the other INSYS Modem 56k Small INT 2.0 (without dialing).
The behavior of the INSYS Modem 56k Small INT 2.0 depends on the activation of the
line current recognition (see ATX command).

The execution of the ATD command also depends on when the last dialing attempt was
performed.

In the mode AT+FCLASS=0, the INSYS Modem 56k Small INT 2.0 acts like a data mo­dem. It attempts to connect to another data modem. This attempt is repeated until the
waiting period that was specified in the S7 registry has expired.

If this period is exceeded, the INSYS Modem 56k Small INT 2.0 hangs up and the follow­ing error message appears: NO CARRIER.

In the mode FCLASS=1 or =2, the INSYS Modem 56k Small INT 2.0 acts as a fax modem.
It attempts to connect to another fax or fax modem. (The INSYS Modem 56k Small INT

2.0 goes into receive status HDLC V.21 channel 2, as if the command AT+FRH had been
executed.)

The following characters may be transmitted as parameters (brackets, punctuation
marks, spaces and semicolons are ignored):

0 to 9 The digits from 0 to 9

* The asterisk: Only for tone dialing

# The hash: Only for tone dialing

A-D The inband signaling characters A, B, C, D

P Pulse dialing mandatory: Pulse or tone dialing is required according to

the region.

T Tone dialing mandatory: Pulse or tone dialing is required according to

the region.

W Wait for dialing tone: The INSYS Modem 56k Small INT 2.0 waits for the

dialing tone before it starts to dial. If no dialing tone was detected
within the period specified in the S6 registry, the INSYS Modem 56k
Small INT 2.0 hangs up and an error message is displayed.

@ Waiting for silence: The INSYS Modem 56k Small INT 2.0 waits at least

five seconds for silence in the line, before it executes the next character
from the parameter string. If this five second silence can not be de­tected and the abort period in the S7 registry has not been exceeded,
the INSYS Modem 56k Small INT 2.0 terminates the connection display­ing the message: NO ANSWER.

If busy signal recognition was activated, the INSYS Modem 56k Small

INT 2.0 terminates the connection displaying the message: BUSY.

If a response tone from the other INSYS Modem 56k Small INT 2.0 is re­ceived during the waiting period, a connection is established.

tone delay before it executes the next character of the parameter
string. The delay length is defined in the S8 registry.

L Last number re-dialing.

; Return to the input mode after dialing. It is added to the end of the

dialing string and causes the INSYS Modem 56k Small INT 2.0 to return
to the entry mode when it reaches “;” (with: message OK). This enables
the input of AT commands even with a receiver off-hook. The additional
AT commands can follow in the same input line after the “;” or they
can be transmitted to further input lines. The ATH command will abort
the connection and the receiver is hung up.

S=n Dialing the n-th number from the number pool, which was set up with

the AT&Z<n> command.

! If the character ”!” is a part of the dialing string, the INSYS Modem 56k

Small INT 2.0 will hang up within the time frame determined in S29 and
then goes off-hook again.

^ Suppresses the sending of a ringing tone.

ATD12345; The semicolon (;) causes the return to the input mode after dialing.

Default: Ringing tone is sent for fax operation. No ringing tone for data opera-

tion.

For PBXs, which connect to the exchange line using the prefix 0 (or 9):

First, blind dialing is activated by: X3 (see the command „ATX3“) to be
able to dial a leading 0 without hearing a dialing tone. After 0 has been
dialed via: D0 dialing tone recognition can be switched on again using
the parameter: W. The INSYS Modem 56k Small INT 2.0 thus waits for
the dialing tone and continues with the rest of the dial-up (via: 12345)
only after hearing the dialing tone. Waiting for the dialing tone may be
omitted. In this case, the dialing command is ATX3D012345.

command AT\B will send a break to the other modem. In this situa­tion, the parameter n will cause the following:

AT\K0 INSYS Modem 56k Small INT 2.0 deletes the data buffer and sends a

break to the other modem

AT\K1 See AT\K0

AT\K2 INSYS Modem 56k Small INT 2.0 sends a break to the other modem

without delay.

AT\K3 See AT\K2

AT\K4 INSYS Modem 56k Small INT 2.0 inserts a break into the data transmit-

ted to the other modem

AT\K5 See AT\K4 – Return from the online command mode into the data

mode via the ATO command.

3. Situation In the case a break is received from another modem during a connec-
tion that has not been error corrected, the parameters cause the follow­ing:

AT\K0 INSYS Modem 56k Small INT 2.0 deletes the data buffer and sends a

break to the PC

AT\K1 See AT\K0

AT\K2 INSYS Modem 56k Small INT 2.0 sends a break to the PC without delay

Command Description

ATL<n> Speaker volume

This command regulates the speaker volume (see command ATM).

ATL1 Speaker volume low (default)

ATL2 Speaker volume medium

ATL3 Speaker volume high

AT%L Display level of the received signal

The value that is reported from the INSYS Modem 56k Small INT 2.0 equals the already
amplified level within the INSYS Modem 56k Small INT 2.0, not the phone line level.

Large AT%L responses imply a low signal level; small values imply a high signal level

(009 = -9db, 043 = -43db)

AT*L<n> Determines the automatic speed limitation

The automatic speed limitation is used to automatically achieve the least possible error
rate for connections without error correction.

In the factory settings the speed limitation is always switched on (AT*L0).

If the limitation is switched off (AT*L1), the INSYS Modem 56k Small INT 2.0will always
establish the connection on the phone side with the maximum possible speed (or the
speed defined with AT+MS), irrespective of the data rate at the serial interface. This
means that the INSYS Modem 336 will, for example, always attempt to establish a
33600 baud connection, even if the serial interface is only set to 9600 baud. Without
error correction the high speed will obviously lead to higher bit error rates, which is
usually disruptive.

The automatic speed limitation (AT*L0) will limit the speed on the phone side to the
speed of the serial interface.

It should only be switched off if very low baud rates are employed or if the speed of the
serial interface is changed during the connection.

ATM<n> Speaker control

This command regulates when the speaker is active

(see command ATL<n>).

ATM0 Speaker always OFF

ATM1 Speaker ON during dialing and connection setup (default)

ATM2 Speaker always ON

ATM3 Speaker on during connection setup

Command Description

ATP Switch on pulse dialing method (deactivated for some models)

Starting with this command, each dial-up is performed with the pulse dialing method,
until an ATT or ATDT command switches it back to tone dialing.

AT*P<n> Password query

AT*P0 Switches the password query off after the connection has been estab-

lished. (default)

AT*P1 Switches the password query on after the connection has been estab-

lished.

If the password query is activated, the INSYS Modem 56k Small INT 2.0 will query the
password after CONNECT has taken place. After the password has been entered cor­rectly, the actual CONNECT will take place and data may be transmitted. If a wrong
password was entered, the INSYS Modem 56k Small INT 2.0 will hang up. The password
is the same as for remote control and is set with AT*C .

ATQ<n> Quiet control

This command toggles sending messages from the INSYS Modem 56k Small INT 2.0 to
the application ON and OFF.

ATQ0 Send messages to application (default).

ATQ1 Don’t send messages to application.

AT%Q Display telephone call quality

Displays the quality of the data connection (deviation from the eye diagram). Low val­ues indicate a good line quality. The line quality value must be evaluated differently
depending on the negotiated data rate.

Connections with more than 9600 baud will reach the value “000” for good lines and
should not have values of more than “010”.

For connections with 33600 baud good lines will have values between 010…030. De­pending on the settings and the modulation type a fall back or retrain is triggered if the
line quality is too bad to enable a new negotiation of the connection (if necessary with
a slower speed).

High values indicate bad quality. These values are constantly updated during a connec­tion. If the value increases significantly during a connection, the quality will deteriorate.
After a previous AT%E command, an Autoretrain is performed.

Command Description

AT\Q<n> Quiet Call

Quiet Call will switch of the phone connected in series at the first ring. In connection
with the selective call answer (AT&N<n>), calls from a previously defined phone num­ber can take place without a ring of the phone connected in series. If the phone number
is not detected by the INSYS Modem 56k Small INT 2.0, the phone is switched on again
after the first ring.

AT\Q0 Switches Quiet Call off (default)

AT\Q1

Activates Quiet Call. The phone connected in series is disconnected,

as soon as an entire ring signal cycle is detected on the line.

AT\Q2 Activates Quiet Call. The phone connected in series is disconnected,
as soon as a ring signal flank is detected on the line.

The selection between the settings \Q1 or \Q2 depends on the circumstances at the
phone connection. For \Q2 in connection with pulse dialing, phones that are connected
in parallel will sometimes result in an erroneous detection of a ring signal flank. When
using pulse dialing at the phones connected in series, AT\Q1 must be used.

AT&R<n> RTS/ CTS behavior

This command determines how the INSYS Modem 56k Small INT 2.0 treats the RTS/CTS
(CT105/CT106) data flow control lines.

(See also command AT&K).

AT&R0 CTS behavior complies with V.25bis. CTS is deactivated during the con-

nection setup after recognition of the response or ringing tones and will
only be activated after the connection is set up. During the controlled
half duplex operation (AT&K8) CTS is active, if the INSYS Modem 56k
Small INT 2.0 sends data at the serial interface. When data is received at
the serial interface, CTS is inactive.

AT&R1 CTS only switches to OFF when this is required by the data flow control.

During the controlled half duplex operation (AT&K8) CTS is inactive, if
the INSYS Modem 56k Small INT 2.0 sends data at the serial interface.
When data is received at the serial interface, CTS is active. (default)

AT*R<n> Switches the remote control on and off

AT*R0 Switches the remote control OFF.

AT*R1 Switches the remote control ON (default).

ATS<n> Read/write of the S registry

Depending on the country settings, the S registries may only be changed within certain
limits. The INSYS Modem 56k Small INT 2.0 still reports OK although the value has not
changed. We recommend checking the results after each write attempt, using the

ATS<n>? command.

ATS<n>=<x> Sets the S registry n to the value x.

AT&V0 The active configuration of the modem, the saved user defaults and the

saved phone numbers 0 to 3 (the parameter 0 may be omitted) are dis­played.

AT&V1 Displays the diagnostic data of the last connection (connection partner,

reason for disconnect).

TERMINATION REASON: Reason for disconnect.
E.g.: Connection termination via command (ATH: “LOCAL REQUEST”).

LAST TX rate: Last baud rate at the phone line in send direction,
prior to the termination.

HIGHEST TX rate: Highest baud rate that was achieved at the
phone line in send direction, prior to the termination.

LAST RX rate: Last baud rate at the phone line in receive direction,
prior to the termination.

HIGHEST RX rate: Highest baud rate that was achieved at the
phone line in receive direction, prior to the termination.

Note: The data rates may vary if a fall forward, fall back or retrain
occurred during the connection. To impact the negotiated data rate,
use the command AT+MS.

PROTOCOL: Displays the used error correction protocol. “LAPM“ equals
a V.42 secured connection. For “NONE”, the connection was not error
corrected (the error corrected can be influenced with the command

AT\N).

COMPRESSION: Displays the used data compression method. The ex-

ample shows the used compression method V.42bis (the compression
method can be set with the command AT%C).

LINE QUALITY: Displays the quality of the data connection (deviation
from the eye diagram). Low values indicate a good line quality. The line
quality value must be evaluated differently depending on the negoti­ated data rate.

Connections with more than 9600 baud will reach the value “000” for
good lines and should not have values of more than “010”.

For connections with 33600 baud good lines will have values between
010…030. Depending on the settings and the modulation type a fall
back or retrain is triggered if the line quality is too bad to enable a new
negotiation of the connection (if necessary with a slower speed).

Rx LEVEL: Displays the receive level (which is internally applied at the
modem chip) in –dBm. High values indicate a low input level; low val­ues indicate a high input level. The optimum receive levels range from
approx. 012 to 028. To high levels could cause distortions; too low levels
will cause the line noise to have a negative impact on the connection
quality.

Local Rtrn Count: Number of retrains (renegotiation of the con­nection), triggered by the local modem.

Remote Rtrn Count: Number of retrains (renegotiation of the con­nection), triggered by the remote modem.

dialing string (see command ATD). In the mode AT+FCLASS=1,2 the INSYS Modem
56k Small INT 2.0 always sends the message CONNECT to the PC without specifying the
transmission speed.

ATX0 No detection of the dialing tone, i.e. an unsuccessful dialing attempt

leads to the message NO CARRIER.

No detection of the busy signal, i.e. when calling a busy line the mes-

sage NO CARRIER is displayed. The message is displayed without
specifying the speed.

ATX1 As ATX0, but the CONNECT message contains the speed specification.

ATX2 Dialing tone detection is active, i.e. a dialing attempt without the pres-

ence of a dialing tone leads to the message NO DIALTONE.

No detection of the busy signal, i.e. when calling a busy line the mes-

sage NO CARRIER is displayed.

ATX3 No detection of the dialing tone, i.e. an unsuccessful dialing attempt

leads to the message NO CARRIER.

Busy signal detection active, i.e. when calling a busy line the message

BUSY is displayed.

ATX4 Dialing tone detection is active, i.e. a dialing attempt without the pres-

ence of a dialing tone leads to the message NO DIALTONE. (default)

Busy signal detection is active, i.e. when calling a busy line the message

BUSY is displayed.

AT*X Terminate remote configuration

The command AT*X terminates a remote configuration.

AT&Y<n> Selection of user configuration for hardware reset

AT&Y0 For a hardware reset following the AT&Y0-command, the user default 0

(created using the AT&W0 command) is loaded into the current modem
configuration.

AT&Y1 For a hardware reset following the AT&Y1-command, the user default 1

(created using the AT&W1 command) is loaded into the current modem
configuration.

ATZ<n> Software reset

The command causes the INSYS Modem 56k Small INT 2.0 to perform a software reset.
The INSYS Modem 56k Small INT 2.0 will load the default saved by the user (according
to the parameter). If no parameter is specified, the user default 0 is loaded.

ATZ0 Software reset; afterwards the user default 0 is loaded.

ATZ1 Software reset; afterwards the user default 1 is loaded.

Table 10: AT responses depending on the ATX command

Notes regarding the table:

An X in the column indicates that a message is either sent in long or short form
(depending on the ATV command). In the topmost line, the characters 0 to 4 each
indicate the parameters for the commands ATX0 to ATX4.

If there is a number in a column, this indicates that an error message is displayed
according to the error number.

S registries may be read and written using the ATS<n> command. (See Chapter 1,
command ATS<n>) Certain S registries may only be read; into others only a par­ticular range of values may be entered.

If the range of values is exceeded, the modem will report OK, although the value
was not accepted. We therefore recommend to immediately check modifications
by reading (ATS<n>?).

Note:
* These registries are stored in the user defaults with AT&W0 or AT&W1.
** The defaults can differ depending on the set country code.

17.2 Description S Registry

Note: Registries marked with *) are stored in the user defaults with the command

AT&W- Befehl.

S0* Number of ringing tones until automatically going off-hook

Number of rings until the modem goes off-hook
For S0=0 the modem will not go off-hook when a call comes in. The value of S0

can be between 0 and 5.

S1 Ringing tone counter

Counter for call ringing. S1 is read-only. S1 will be reset to zero, when the modem

answers a call.

S2* Escape
Escape character which causes a switch from data mode to online command input

mode. Values larger than 127 will lead to the fact that no ESC character will be
recognized.

S3 Return

Carriage Return Character (CR).

S3 Linefeed character
Linefeed character

S5 Backspace character
Backspace character

S6* Waiting period dial tone
Maximum waiting time for the dialing tone. After the modem went off-hook it

waits 7 seconds for the dialing tone (fixed for approval purposes). If it detects a
dialing tone during this waiting period it will start dialing.

If it does not detect a dialing tone, it will check if dial tone recognition is activated
or if the dialing string (Chapter „AT Command Set“, command ATD) contains the
parameter W. If the dialing tone detection is not activated, the modem waits for
the dialing tone. The waiting time (in seconds) is specified in S6.

The value of the S6 registry can be between 4 and 7 seconds.

S7* Waiting period carrier signal
Wait for the carrier frequency from the other modem. The maximum time for the

modem to wait for a response from the other modem is specified in S7. The time
starts running as soon as the modem has finished dialing. The value of S7 can be
between 0 and 180 seconds.

S Registry INSYS Modem 56k Small INT 2.0

86

S8* Dial tone delay
Dial pause time, if a comma is included in the dialing string. If there is a comma in

the dialing string, the modem will wait during the dialing procedure, until the
time specified in S8 (in seconds) has run out. The value of S8 can be between 1
and 7 seconds.

S9* Reaction time carrier signal
DCD response time for the carrier frequency from the other modem. The DCD

output of the RS232 interface (CT109) of the modem switches to ON, when the
carrier frequency from the other modem is detected before the time defined in S9
(in tenth of seconds) runs out. S9 must be smaller than S10.

S10* Time period between lost carrier signal and hang up
The time which leads to termination after carrier frequency loss. In S10, the time

period for which the modem waits for the disconnection if it can no longer detect
the carrier frequency from the other modem, is specified in tenth of seconds.

S12* Transmission clock of the ESC characters
Minimum pre and post run time and maximum interim time in 1/50 of seconds

between two characters. This must be observed, if the modem is supposed to de­tect an abort sequence (usually +++).

S13* Number of dialing attempts to send a message

Bit Meaning

Bit 0 – 3 Number of dialing attempts

Range of values: 1...12
Default value: 3
S13 determines the number of attempts to send the

message.

S15* DTC Time Settings

The idle connection control is a function integrated in the firmware which moni­tors the data transmission in online mode. This function prevents the modem to
stay online for an unlimited amount of time, although no data is being transmit­ted anymore.

In the registry S15, any time period between 1 and 255 seconds may be entered. If
S15 is set to 0, the idle connection control is switched off.

The timer will run immediately after the modem goes off-hook. As soon as the
timer has run out, a modem reset is performed (which will forcibly lead to the
hanging up of the modem).

S17* Initial character for remote configuration

In S17, the ASCII code of a character which is used to start the remote configura­tion, is defined. Values >127 switch the remote configuration off completely. The
default setting in S17 is “42”, which equals the ASCII character “*”. This means
that the remote configuration is started with the Escape character sequence

<Pause> **** <Pause>.
Note: The number of characters in the Escape sequence is fixed to “4” characters).

as soon as characters are sent to the modem, or when a call comes in.

Note: When the modem is in sleep mode, it is necessary to send an

“AT” command before sending other commands. This first “AT”
command may not be answered with “OK”. Further AT com­mands may be entered immediately.
