Download (or make notes of) the settings of your INSYS
Modem 56k Small INT 2.1 before you change the country specific preset.
The INSYS Modem 56k Small INT 2.1 holds a range of presets, which allow you to adjust the device to the standards and requirements of the local telephone network. You find a list of countries and the corresponding country codes in the
“Country Codes” section.
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 2.1 in the software HSComm on the “Modem”
tab in the panel International Settings (Page 33, Figure 5: HSComm Modem - Tab Modem, Position 14).
Configuration with AT commands
To choose the preset for the country where the INSYS Modem 56k Small INT 2.1 is deployed, use the command:
AT+GCI=<n>
12.2 Establishing or Accepting a Data Connection
The INSYS Modem 56k Small INT 2.1 can call another modem via the phone line and establish a data connection. After dialling a phone number, the INSYS Modem
56k Small INT 2.1 synchronises with the called modem and opens a data connection with the transmission speed, which is currently set at the serial interface. All incoming characters are transmitted to the other (called) modem during the active data connection. Therefore, AT commands are not processed during a connection.
The INSYS Modem 56k Small INT 2.1 must be changed to command mode again using an "Escape sequence" that it processes AT commands again during an active connection. Then, the local INSYS Modem 56k Small INT 2.1 processes the entered
36
INSYS Modem small INT 2.1 Functions characters as AT commands and does not transmit them to the remote terminal. A remote INSYS Modem 56k Small INT 2.1 can be changed to command mode during an active data connection using the function "Remote configuration".
The INSYS Modem 56k Small INT 2.1 can accept an incoming connection in the same way. For this, the "application" or the PC with the terminal program at the serial interface must have DTR signalling enabled, otherwise, the INSYS Modem
56k Small INT 2.1 does not accept the incoming connection. In this case, DTR signalling must be disabled in the INSYS Modem 56k Small INT 2.1 that a connection is accepted regardless of the status of the application. The status of the hardware data flow control (enabled by default) must also be considered. It answers after the configured number of ring tones and opens a connection.
Configuration with AT commands
The HSComm enables to establish a connection via the integrated termi-
nal program. Click "Terminal" (page 33, Figure 5: HSComm Modem - Tab
Modem, position 3) in the menu bar of HSComm, to open the integrated
terminal program.
Configuration with AT commands
In order to establish a data connection with the INSYS Modem 56k
Small INT 2.1, use the command
ATD<number>
Replace <number> with the phone number of the remote terminal.
In order to explicitly use tone dialling for dialling the number, use the command
ATDT<number>
In order to explicitly use pulse dialling for dialling the number, use the command

INSYS Modem small INT 2.1 Functions
12.3 Automatic Baud Rate Detection
12.3.1 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 2.1. 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 2.1 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 2.1 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 2.1 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 2.1 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 2.1.
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.
AT+IPR=<n>
This setting can not be stored.
The INSYS Modem 56k Small INT 2.1 must be configured with the baud rate, which is used to operate the application at a later time, as the IN-
SYS Modem 56k Small INT 2.1 will always use the last known functioning configuration of its interface.
39
Functions INSYS Modem small INT 2.1
12.3.2 Phone Connection
The automatic negotiation of the baud rate and the modulation standard enables the INSYS Modem 56k Small INT 2.1 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 2.1 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 2.1 via the entry field "Initialization string" (Page 33, 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=?
12.4 Data Buffer for Serial Data Transmission
The INSYS Modem 56k Small INT 2.1 provides 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
2.1. If the buffer overflows, the data gets lost. Operation without a buffer and error correction is only useful for special character framings
.
The function is active as default.
40
Configuration with HSComm
Select the type of error correction on the tab Modem in the panel "Phone
interface" (Page 33, Figure 5: HSComm Modem - Tab Modem, Position
25). Buffering is active for all options except the option "unbuffered, bit
INSYS Modem small INT 2.1 Functions direct". To deactivate the buffer (and simultaneously the error correction), select "unbuffered, bit direct".
Configuration with AT commands
To deactivate the error correction as well as the buffer in the INSYS Modem 56k Small
INT 2.1 for applications with special data format, use the command:
AT\N1
To deactivate only the error correction, use the command:
AT\N0
12.5 Bit Direct Mode
For special applications, the buffering of the INSYS Modem 56k Small INT 2.1 can be deactivated using the setting "unbuffered, bit direct". All data is forwarded without buffering and further influence of the INSYS Modem 56k Small INT 2.1.
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 2.1 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 special character framings.
Configuration with HSComm
Select the type of error correction on the tab Modem in the panel "Phone
interface" (Page 33, 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 2.1 and to switch on the bit direct mode, use the command:
AT\N1
12.6 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.
12.6.1 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
41
Functions INSYS Modem small INT 2.1 the application to interrupt the dataflow. When the buffer is emptied sufficiently for the INSYS Modem 56k Small INT 2.1 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 2.1 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 2.1.
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 33, Figure 5: HSComm Modem -
Configuration with AT commands
To switch the data flow control on and to set the type to RTS/CTS, use:
To switch the data flow control off, use:
AT&K3
AT&K0
12.6.2 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.

12.7 Error correction
The INSYS Modem 56k Small INT 2.1 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 33, Figure 5: HSComm Modem - Tab Modem, Position 25).

12.8 Data Compression
The INSYS Modem 56k Small INT 2.1 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 MNP 5 and V.42bis and V.44 data compression (AT%C3).
Configuration with HSComm
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 2.1 via the entry field "Initialization string" (Page 33, Figure 5:
HSComm Modem - Tab Modem, Position 13).

12.9 Selective Call Acceptance
The selective call acceptance enables to define, which calls are accepted by the
INSYS Modem 56k Small INT 2.1. If the selective call acceptance is activated, the
INSYS Modem 56k Small INT 2.1 will only accept calls from previously defined callers. The INSYS Modem 56k Small INT 2.1 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 2.1 has 8 storage locations altogether (N0 to N7).
The INSYS Modem 56k Small INT 2.1 checks in the phone number transmitted via
CLIP, whether one of the numbers stored in the list is contained. The check will be started „from right“, i.e. the end of the phone number transmitted via CLIP. This enables to recognize a phone number even if „+49“ or „0049“ or a different prefix has been put in front. Moreover, the number stored for recognition can remain variable using „wildcards“ at certain positions. The stored phone number must not contain separators, like hyphens between area code and phone number for example.
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:

12.10 Sending messages via data connection, SMS or Fax
The INSYS Modem 56k Small INT 2.1 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 35,
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 en-
tered in the entry field "Character for exchange" (Page 35, 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
cipient with the prefix (or the country prefix) into the field under "Phone

12.15 Idle Connection Control with Data Transmit Control
The Data Transmit Control (DTC) is a function of the INSYS Modem 56k Small INT
2.1 which monitors the data transmission in online mode. This function prevents the INSYS Modem 56k Small INT 2.1 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 2.1 will hang up as soon as there is no data transfer on the phone line.
Configuration with HSComm
A direct configuration with the software HSComm is not intended.
Configuration with AT commands
To define the time, after which the INSYS
Modem 56k Small INT 2.1 should hang up, if no data transmission is available, use the command
You can select a value between 1 and 255 seconds for <n>. Please note that the timer will start running, as soon as the INSYS

12.16 Priority Circuit for a Phone Connected in Series
The INSYS Modem 56k Small INT 2.1 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 2.1 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 off-hook or if the remote terminal of the INSYS Modem 56k
Small INT 2.1 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

No connection has been established. The line is free.
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 2.1 can thus detect that the line is busy.
A connection has been established, but this time the INSYS Modem 56k Small
INT 2.1 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 2.1 will detect that the phone has gone off-hook and will terminate the connection.
The line is busy during a modem connection. After the remote terminal hangs up, the INSYS Modem 56k Small INT 2.1 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 2.1 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.
Table 9: Line states and behavior of the priority circuit
Configuration with HSComm
This function can not be set directly via the configuration software
HSComm. The according AT command to activate the priority function can be sent to the INSYS Modem 56k Small INT 2.1 via the entry field
"Initialization string" (Page 33, Figure 5: HSComm Modem - Tab Modem,
Position 13).

INSYS Modem small INT 2.1
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 2.1 has already gone off-hook and a telephone connected in series is going off-hook.
AT-TTE=U1,U2,U3
U3 is the voltage difference in the phone line between hung up state (free line) and the busy line.

AT Command Reference INSYS Modem small INT 2.1
Command Description
ATD<n>
Dial
The INSYS Modem 56k Small INT 2.1 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 2.1 attempts to establish a connection. If the ATD command was performed without a dialing string, the INSYS Modem 56k Small INT 2.1 goes offhook and attempts to connect to the other INSYS Modem 56k Small INT 2.1 (without dialing). The behavior of the INSYS Modem 56k Small INT 2.1 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 2.1 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 2.1 hangs up and the following error message appears: NO CARRIER.
In the mode AT+FCLASS=1 or =2, the INSYS Modem 56k Small INT 2.1 acts as a fax modem. It attempts to connect to another fax or fax modem. (It 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):

Pulse dialing mandatory: Pulse or tone dialing is required according to the region.
Tone dialing mandatory: Pulse or tone dialing is required according to the region.
Wait for dialing tone: The INSYS Modem 56k Small INT 2.1 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 2.1 hangs up and an error message is displayed.
@
Waiting for silence: The INSYS Modem 56k Small INT 2.1 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 2.1 terminates the connection displaying the message: NO ANSWER.
If busy signal recognition was activated, the INSYS Modem 56k Small
INT 2.1 terminates the connection displaying the message: BUSY.
If a response tone from the other INSYS Modem 56k Small INT 2.1 is received during the waiting period, a connection is established.

ATL<n>
Speaker
This command regulates the speaker volume (see command ATM).
ATL1
ATL2
ATL3
Speaker volume low (default)
Speaker volume medium
Speaker volume high
AT%L
Display level of the received signal
The value that is reported from the INSYS Modem 56k Small INT 2.1 equals the already amplified level within the INSYS Modem 56k Small INT 2.1, 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 2.1 will 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.

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.

AT Command Reference
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.
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 example 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.
Display of the currently set baud rate (AT*S<n>) as well as the currently set data format (AT*U<n>).

Description
Extended result messages, dial tone detection
AT Command Reference
The command determines which group of messages the INSYS Modem 56k Small
INT 2.1 sends to the PC. This is important for PBXs, as a leading 0 or 9 must often be dialed before a dialing tone is heard on the line.
Blind dialing (dialing without detecting the dialing tone) is activated or deactivated according to the parameter. The detection of the dialing tone, however, can always be enforced using the parameter W in the ATD dialing string (see command ATD). In the mode AT+FCLASS=1,2 the INSYS
Modem 56k Small INT 2.1 always sends the message CONNECT to the PC without specifying the transmission speed.
AT*X

Note: Registries marked with *) are stored in the user defaults with the command
AT&W
.
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).
Linefeed 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.
98
INSYS Modem small INT 2.1 S Registry
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:
Default value: 3
1...12
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).

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.
