CHAPTER 0 INSTALLATION WLAN
Chapter 1 INTRODUCTION The Data Modem you have purchased represents the latest state of the art in data communication; its comprehensive facilities provide all you will need for professional data transfer purposes. Due to the limitation this equipment allows you to receive data with up to 54kbps from your Internet Service Provider (ISP). The maximum transmission speed is 33.6kbps. Fax transmission and reception is working up to 14.4kbps.
The 56K Technology The V.90 modem represents the latest V.90 technology. This allows receive data rates of up to 57.333 kbps over PSTN (public switched telephone network) only in connection with equipment-compatible ISPs (Internet Service Provider): however, due to the limited power levels of the PSTN the receive speed is limited to 54 kbps.
Auto-Answering With the delivered Software you can use your Modem like an answering machine. Voicemail can be recorded over the soundcard. To replay recorded voice or messages you can use a soundcard. Installation Instructions 1. Plug in the PCI-Card into a free PCI Slot of your PC. 2. Connect the modem card to the enclosed telephone cable and your analogue telephone connection (RJ11-socket). Installation under Windows 95/98 Windows 9x will recognize the modem after a reboot of your PC.
To use the modem in a Dial-Up Network, it must be added to the RAS service -> Start – Settings – Control Panel – Network (refer to the instructions in the Windows manual). To uninstall, remove the entry of the card in the -> Control Panel under -> Modems and uninstall the installation software using -> Control Panel – Software. Installation under Windows 2000 Unpack the driver (diskette or Internet) into a temporary folder.
Chapter 2 AT COMMANDS: DATA MODEM Guidelines for Using AT Commands The modem is programmed with AT commands from the data terminal equipment (computer, PC or terminal) and thus also receives instructions to cover automatic dialing. The communications or fax software will carry out most of these operations for you, so that in general circumstances you do not need to have a detailed understanding of the commands which are described below. The modem must be in Command mode before it can accept commands.
Table 1 Modem Commands Standard Commands ATA A/ ATB ATD Answer mode: Modem monitors telephone line Repeat last command line; entered without “AT” Switching between BELL/CCITT Standards at 300 or 1200 bps Enter automatic dialing ATE ATH ATI ATL Controlling of echo modem commands on screen Break off an existing connection Information on Modem product code Loudspeaker volume control ATM ATN ATO Switch on and off loudspeaker Select Data Rate Handshake Return to Online-mode after entering Esc sequence AT
Extended MNP- and V.42bis-Commands AT\T Set Inactivity Timer AT\X AT-J AT%C AT%E Set XON/XOFF Pass-Through Set V.42 Detect Phase MNP 5 Data Compression Control Auto Retrain Control AT%G AT"H AT"O Rate Renegotiations V.42 bis Compression Control V.42 bis String Length AT - Attention Code The AT (Attention) Code, which introduces each command line, can be entered in upper-case or lower-case characters. Several commands (separated by spaces if desired) can be positioned one after another, in one line.
A - Answer Mode When the A command is entered, the modem switches to the “Off-Hook” condition when ringing appears in the answer mode and takes over control of the telephone line connected. In this way, the modem transmits in the upper frequency band (upper channel). If further commands are entered after the A command before a connection has been made, the modem interrupts the establishment of a connection, switches to command mode and issues a NO CARRIER message.
D - Automatic Dialing and Dialing Parameters The D command instructs the modem to go on-line and to dial. If this command is entered without parameters, the modem will go on-line in Originate mode. The following characters are authorized in the dialing sequence: 0-9 The digits of the telephone number P, T In the Dial command, these parameters switch to pulse-dialing (P) or to tone-dialing (T) until the other parameter is entered. The standard setting is tone-dialing. W Dialing tone recognition.
E – Echo Function The E command determines whether the modem will issue an echo of the command which is entered. ATE0 Echo disabled ATE1 Echo enabled (factory setting) H – Switch Hook Control (Replace Handset) – Go "On Hook" The H command will break off the existing telephone line connection (the modem “hangs up”) and the connection to the remote modem is cut off. After the H command, any other commands in the same line are ignored.
N – Recognizing Type of Modulation This command commands the automatic recognition of the type of modulation. ATN0 When originating or answering, connect only at the data rates specified by the modulation. ATN1 When originating or answering, begin handshaking at the modulation data rate. If the remote modem does not support the specified modulation data rate, fall down in data rate or modulation to the highest compatible data rate.
W – Controlling Connect Messages This command controls the format of CONNECT messages. ATW0,1 CONNECT result code reports DTE speed ATW2 CONNECT result code reports DCE speed ATW3 CONNECT result code reports DTE data rate, modulation mode, error correction, data compression, DCE transmitter speed and DCE receiver speed when the mode is configured for verbose V1 (text) response codes. For numeric responses V0, the modem responds with the W0 numeric response codes.
X – Result Code Type/Call Progress This command determines which modem result codes are enabled. Additionally, this command specifies whether busy and dial tone detection are enabled or disabled.. ATX0 Result codes 0-4 enabled. Busy and dial tone detect disabled. ATX1 Result codes 0-5, 10 and above enabled. Busy and dial tone detect disabled. ATX2 Result codes 0-6, 10 and above enabled. Busy detect disabled and dial tone detect enabled. ATX3 Result codes 0-5, 7, 10 and above enabled.
&D – DTR (Data Terminal Ready) Option This command controls how the modem responds to DTR. After toggling DTR, the host should wait 200 ms before modifying the UART registers or sending a new command to the modem. This is done because the modem does not send an ’OK’ message to indicate it has performed the requested function. AT&D0 In asynchronous mode (&Q0), the modem ignores DTR. AT&D1 The modem switches from data mode to command mode when an on-to-off transition of DTR occurs.
&G – Guard Tone This command controls whether the modem sends out guard tones while connected to a remote modem (for ITU-T V.22 bis {1200 bps} and V.22 bis {2400 bps} connections only). Guard tones are sent by the answer modem to disable Central Office echo cancelers. AT&G0 Guard tone disabled (factory setting) AT&G1 550 Hz guard tone enabled AT&G2 1800 Hz guard tone enabled &K – Select Serial Port Flow Control This command specifies the DTE-to-modem flow control.
&V – View Active Configuration and Stored Profiles This command causes the modem to display the command and S-Register information contained in the active user profile and in one or two stored profiles. The command &V0 displays the active profile and the stored profile 0; &V1 displays the active profile and the stored profile 1. The information in the active profile is stored into the user profiles with the &Wn command. &W0 stores the active profile into the stored profile 0; &W1, the stored profile 1.
&Z – Telephone Number Storage The modem can store up to 4 telephone numbers by using the AT&Zn=x command (n= 0-3). These can be dialed automatically by the command ATDS=n. Telephone numbers must not be more than 45 characters in length (digits + dialing parameters). For example: AT&Z2=T06897 123456 The telephone number T (tone dialing) 06897 123456 is stored in memory 2. +MS – Select Modulation This command sets the type of modulation used and the send and receive speeds.
V23C V32 V32B V34 V34S V34B V34BS V90 V.23, with constant carrier, 1200 bps forward and 300 bps reverse V.32 4800 and 9600 bps V.32 bis 7200, 9600, 12,200, and 14,400 bps V.34 asymmetrical connections: 2400, 4800, 7200, 9600, 12,200, 14,400, 16,800, 19,200, 21,600, 24,000, 26,400, 28,800, 31,200, and 33,600 bps V.34 symmetrical-only connections: 2400, 4800, 7200, 9600, 12,200, 14,400, 16,800, 19,200, 21,600, 24,000, 26,400, 28,800, 31,200, and 33,600 bps V.
= 0 Minimum allowed data rate - = 1 Lowest data rate = 300 bps - = 0 Lowest data rate = (Lowest modulation data rate) =/ 0 Lowest permitted connection rate This parameter sets the highest speed at which the modem may establish a connection. This feature is also controlled by the S37 S-Register.
\A – MNP Block Size This command specifies the maximum number of data bytes in an MNP data frame. A smaller size may improve throughput on high-impairment (noisy) telephone lines. AT\A0 Maximum block size is 64 bytes AT\A1 Maximum block size is 128 bytes AT\A2 Maximum block size is 192 bytes AT\A3 Maximum block size is 256 bytes (factory setting) \B – Sending a Break Signal The \B command is used to send a Break signal to the remote modem (see \K command). In order to enter the \B command, you must first r
\J – bps Rate Adjust Control If this command is enabled, the serial port speed automatically changes to the modem-connection speed. This forces the user to change the DTE-to-modem bps rate, if needed. If the command is disabled, the serial port speed is independent of the connection speed, which allows much greater throughput when using error connection and data compression AT\J0 Turns off feature AT\J1 Turns on feature \K – Set Break Control Defines what action the modem takes when a break (attention sign
\N – Set Operating Mode Determines the type of connection attempted by the modem. AT\N0,1 Buffer (Normal) Mode – no data compression or error correction, but uses speed buffering. AT\N2 MNP Reliable Mode – the modem attempts to negotiate an MNP error-correction ’reliable’ link, hanging up if it fails. AT\N3 V.42 Auto-Reliable Mode – if V.42 detection is enabled (-Jn), a LAPM or MNP link can be detected and negotiated; otherwise, only LAPM is attempted.
\T – Set Inactivity Timer During a buffer (normal) or reliable connection, if no data is sent or received within the inactivity time period, the link is disconnected. The default, ’0’, disables this feature. AT\T0-90 Length in minutes AT\T0 Disables inactivity timer (factory setting) \X – Set XON/XOFF Pass Through If software flow control is enabled (\Q1), this command defines whether the XON (11h) and XOFF (13h) characters received from the DTE are sent to remote modem.
%E – Auto-Retrain Control This command controls whether the modem automatically initiates a modem retrain whenever the received data signal quality falls below a threshold that may affect data reliability. The value for ’n’ is stored in the NVRAM. AT%E0 Disabled AT%E1 Enabled (factory setting) %G — Rate Renegotiations This command selects whether the modem automatically initiates a change to higher speed or lower speed depending on received signal quality (that is, rate negotiation).
Chapter 3 MODEM MESSAGES The modem responds to AT commands with Modem Messages. You can control their format with the V command verbal (ATV1) or numeric (ATV0). In addition, the modem issues Connection Messages, when it recognizes activities on the telephone line. The X command determines which messages are authorized here. Messages regarding Modulation, Error correction, Datacompression and Data rate are controlled via the W3-command. The following table gives an overview of the possible messages.
Numeric Code Verbose Code 64 CONNECT 28800 65 CONNECT 31200 33 CONNECT 33333 66 CONNECT 33600 34 CONNECT 37333 28 CONNECT 38400 35 CONNECT 41333 36 CONNECT 42666 37 CONNECT 44000 38 CONNECT 45333 39 CONNECT 46666 42 CONNECT 48000 43 CONNECT 49333 53 CONNECT 50666 54 CONNECT 52000 55 CONNECT 53333 56 CONNECT 54666 57 CONNECT 56000 58 CONNECT 57333 18 CONNECT 57600 31 CONNECT 115200 45 RINGBACK See Note CONNECT (DTE data rate) / (modulation) / (error correction)
Chapter 4 S-REGISTERS The modem has a series of S-Registers, in which the active configuration are stored. The contents of some Registers are stored in a non-volatile memory (NVRAM), which can be interrogated with Z, &Y and &W commands. The syntax for entering and requesting Register values is given in the description of the S command. The values of most of the Registers can be modified by using AT commands. Table 4 S-Registers (Summary) Register Range Default.
S0 – Number of Ring Characters before Modem engages If S0-Register is set to S0 = 0, automatic answering is switched OFF and the modem does not go on-line. If S0 = 1, the modem will go on-line at the first ringing sign, or character. Range: 0-9 ringing characters; factory setting: 0 S1 – Ring Character Counter The value of this Register is increased by 1 with each ring which is recognized. It is deleted when pauses exceed 11s.
S6 – Waiting Time for Dial Tone The value of the S6 Register determines when the modem will begin to dial after “going off-hook” (or after recognizing the W parameter in Dialing command mode). The X command controls the effect of the S6 Register. For X0, X1 or X3, the modem waits for the specified period, even if the dial tone occurs earlier. You can enter any value between 0 and 255 sec in this Register; however, the modem will always remain in the allowed range.
S12 – Guard Time for Esc Sequence The Guard Time is the period of time during which, both before and after entering the Esc sequence (+++), the modem is not permitted to receive any characters. Where the Register value is zero, the modem will always go into Command mode after three consecutive Esc signs.

In synchronous operational mode, the measurement units are seconds, while in other operational modes they are hundredths of seconds.
S33 – Sleep Mode Timer S33 determines when the modem enters sleep or power-down mode. When enabled (S33 =/0), the controller enters sleep modem whenever the modem has been in-active for a user-programmable time delay (S33). The modem is considered to be in an inactive state when: 1. No internal processing is being performed 2. No activity occurs between the host and the modem within a specified time period 3.
