USER'S MANUAL

The Federal Communications Commission (FCC) of the United States restricts uses of modems, and places registration responsibilities on both the manufacturer and the individual user:

1.The modem may not be connected to a party line or to a coin operated telephone.

2.The modem manufacturer must make any repair to the modem to maintain valid FCC registration.

3.Notification to the telephone company is no longer required prior to connecting registered equipment, but upon request from the telephone company, the user shall tell the telephone company which line the equipment is connected to as well as the registration number and ringer equivalence number of the registered protective circuitry. FCC information is printed on a label on the bottom of the modem.

This equipment has been tested and found to comply with the limits for a digital device, pursuant to Subpart B and Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates and uses radio frequency energy and if not installed and used the instructions, may cause interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Changes or modification not expressly approved by the manufacturer could void the user's authority to operate this equipment.

Congratulations on your purchase of the V.90 56Kbps Fax/Modem PC card. This manual describes how to operate your new Fax/Modem.

V.90 Technology

V.90 technology is developed to achieve data rates beyond V.34 33.6 kbits/s on connections between an analog (client) modem and a digital (central-site) modem. This is accomplished by recognizing that this connection is fundamentally different from traditional analog point-to-point modem connection. A modulation designed specifically for this type of connection utilizes the available bandwidth to achieve up to 56 kbits/s. With this technology, the downstream data rate to the analog modem is higher than the upstream data rate to the service provider. On connections where the central-site modem is not V.90 capable, the client modem will automatically fall back to X2 or V.34.

When used as data modem your Fax/Modem PC card uses the standard AT command set and is fully compatible with CCITT V.80 V.42, V.42bis, V.34, V.32bis, V.32, V.22bis, V.23, V.22, V.21, MNP2-5, Bell 103 and 212A. When used as a Fax/Data Modem it communicates with all CCITT Group 3 FAX machines and is compatible with CCITT V.27ter and V.29, V.17, T.4 and T.30. Switching between DATA mode operation and FAX mode operation of your Fax/Data Modem is done through its firmware, no hardware settings are required.

If you are already familiar with the use of a modem and the Hayes AT command set, this modem will be extremely easy for you to use. Just read the installation procedures in the driver diskette and you are ready to begin operation. If you are new to modem communications, we recommend that you read through this manual first. If you come across terms that you don't understand, consult the glossary words in boldface type are command names, commands, or default settings. Carriage returns (Enter) are noted with <CR> or [ENTER]; this does not mean to enter these characters literally; but instead to press the Enter key.

If you are going to call a FAX machine then you must use the Fax software. If the machine that you are going to communicate with is a modem then you must use a data modem communications software.

The basic AT commands used to control modem operation are defined in this section. These commands are summarized in Chapter 4. All these commands may not be available in a specific product depending upon supported data rates and modes.

The default values are typical of a fully configured modem supporting all data rates and options. The actual default value is dependent upon modem firmware as defined by the firmware release notes.

AT Command Descriptions

All command lines sent to modem, except for A/, must be preceded by an ‘AT’ and terminated by the contents of S-register S3 (typically a carriage return <CR>). AT stands for ‘attention’ and prompts the modem to receive a command line from the DTE. A <CR> informs the modem that the entire command string has been transmitted and to begin processing all the commands in the command line. A command line can include one or more AT commands. The commands can be separated by a space, if desired, but no

Punctuation is needed except for fax and voice commands. In a multiple-command line, fax and voice AT commands must be separated from following commands by a semicolon (;).

Examples:

ATS1?<CR>

A/

AT &F &D2 +FCLASS=?<CR>

AT +FCLASS=80; S0=1<CR>

The modem provides status information to the DTE in the form of response codes. The supported response codes are listed in Section 2.4.

After sending an AT command string to the modem, the DTE must wait for a response code from the modem before sending a new AT command string to the modem.

Examples of modem responses:

OK

ERROR

CONNECT 288000

In the online state, the DCE is off-hook and communicating with a remote modem. Any data sent from the DTE to the DCE is transmitted to the remote modem. Similarly, any data that the DCE receives from the remote modem is transmitted to the DTE.

NOTE: In the online state, the DCE does not ‘echo-back’ any of the data that the DTE sent to the DCE.

The modem recognizes AT commands from the DTE at any valid data rate from 300 bps to 115,200 bps (that is, the modem autobauds up to 115,200 bps); however, the DTE should use the data rate specified for each mode (see the following table).

Data Rate for Each Mode

Each command may have one or more parameters associated with it. If a parameter is not sent for a command requiring a numeric parameter, then the modem assumes a zero ('0') parameter (only if zero is a valid parameter for the command). For example, ATZ and ATZ0 commands perform identical functions (that is, the modem sees 'ATZ' and automatically uses the '0' parameter during processing the command). Other commands do not use parameters.

AT Escape Sequences

The 56-kbps FAX/MODEM provides two industry-standard escape sequences, TIES (Time Independent Escape Sequence) and the Hayes® Escape Sequence.

The DTE sends the escape sequence to return the modem to command state while in the online data state (that is, connected to another modem) or in diagnostic mode (&Tn commands). Currently, most modems implement the Hayes Escape Sequence; but since its use may require a license from Hayes, TIES is provided as an alternative.

Hayes^® Escape Sequence

The Hayes Escape Sequence, developed by Hayes Microcomputer Products, Inc., has been adopted by many modem manufacturers. The DTE implements the escape sequence by sending the modem an escape character three times, preceded and followed by guard times. Upon detecting the escape sequence, the modem sends and 'OK' response to the DTE. To re-enter the online data state, the DTE then sends the modem ATO followed by the contents of S-register S3 (typically a <CR>).

The escape character is determined by the value stored in S-register S2 and is typically a '+' character. Guard times are silence times when the DTE does not send any data to the modem. Guard times ensure that the modem does not falsely detect an escape sequence if three consecutive escape characters are received from the DTE. The preceding and following guard times are defined in S-register S12. Typically, these guard times are 1 second. In addition to the preceding and ending guard times, there are inter-character time-outs between each escape character sent. The inter-character time-outs define the maximum amount of time allowed between characters before the modem ignores the previous escape characters. This inter-character delay time is set to 1 second. An example of the Hayes Escape Sequence is provided here:

Format: <gt 1><char1><tm 2><char2><tm3><char3><gt4>

char1=char2=char3=escape character(S2)

Example:

DTE: 1 second + + + 1 second

DEC: OK

Time-Independent Escape Sequence

TIES(Time-Independent Escape Sequence)was developed by a group of modem manufacturers as an alternative to the Hayes Escape Sequence. TIES was designed for compatibility with existing communication software written for the Hayes Escape Sequence.

The DTE implements the escape sequence by sending the escape character (as defined in S2) three times, followed by a valid AT command, and then the contents of S3(typically a <CR>). Upon detecting the three consecutive by a valid AT command, and then the contents of S3 (typically a <CR>). Upon detecting the three consecutive escape characters, the modem changes to TIES command mode and starts an internal EPD(Escape Prompt Delay)timer (with the time limit defined by S12). The modem then looks for one of the following conditions to occur:

1) No additional data is received and the EPD timer times out: the modem sends an 'OK' message to the DTE and then waits indefinitely for an incoming valid AT command string from the DTE. Until the modem receives a valid AT command, it monitors any data received from the DTE and passes on the data to the remote modem (that is, the modem does not echo back the received character to the DTE).

a) If the subsequent character received by the modem is not an 'A' or 'a', the modem returns to data mode and sends a 'connect' message back to the DTE.

b) If the modem receives and 'A' or 'a', it stores any additional data received from the DTE in the modem's internal command buffer and continues to send the data to the remote modem. The modem then waits until the DTE sends a <CR>,or up to 39 data characters, before deciding whether to go to command mode or to return to data mode. Upon detecting a <CR> or receiving the 39 data characters, the modem determines if a valid AT command has been received. If a non-AT command string or an invalid command string has been received, then the modem changes back to data mode and sends a 'CONNECT' message to the DTE. If a valid AT command has been received, the modem changes to command mode and sends an 'OK' message. After sending the 'OK' message, the modem echoes any received data from the DTE while in command mode.

2) An 'A' or 'a' is received from the DTE. The modem disables the EPD timer and sends the character to the remote modem. The modem then stores any received data from the DTE into the modem internal command ters, the modem determines if a valid AT command has been received; if so, it processes the valid commands. If a non-AT command string or an invalid command string has been received, then the modem remains in data mode. If a valid AT command has been received, then the modem changes to command mode and sends an 'OK' message. After sending this, the modem (while in command mode) echoes back any data received from the DTE.

3) Any character except an 'A' or 'a' is received from the DTE. The modem disables the EPD timer and changes back to data mode.

If an AT command string is received while in TIES command mode, the modem processes any valid AT command. Upon detecting an invalid AT command, the modem changes back to data mode and issues a 'CONNECT' message to the DTE. While in TIES command mode, the modem ignores certain characters that may cause the modem to incorrectly decide that an incoming AT string is invalid. The ignore characters are<LF>, <space>, and<CR>(<CR> is ignored only when S3 is not equal to <CR>). Not all AT commands are supported during TIES command mode. The following is a list of supported commands:

En, Hn, Mn, On, Sn, Vn, Xn, and '&' commands (except &Tn and &F)

The escape character is determined by the value stored in S-register S2, and it is typically a'+'character. The following is an example of the TIES Escape Sequence:

Format: <char1><char2><char3><AT command><contents of S3>

char1=char2=char3=escape character(S2)

Example:

DTE: + + + AT<CR>

DCE: OK

NOTE: TIES requires the three-character escape sequence be contiguous and not repeated. The character immediately preceding the first character of the three-character sequence cannot be the same as the escape character. Therefore, '+++ AT<CR>'is valid, but '+++ AT<CR>'is not.

Note: An asterisk (*) in the following table denotes factory-default setting.

This card support two types of error correction (MNP*2-4 and V.42 bis) and data compression (MNP 5 and V.42 bis). V.42 error correction uses LAPM as the primary error-control protocol and uses MNP 2-4 as an alternative. V.42 bis data compression requires V.42 (LAPM only). MNP 5 requires MNP 2-4. The supported V.42 bis/MNP AT command set is listed below.

V.42 and MNP Data Mode Command

NOTE: An asterisk (*) denotes the factory-set default setting.

NOTE: An asterisk (*) denotes the factory-default setting.

The modem sends a response to the user via the screen after a command is issued. As shown in the figure below, there are two forms for each result code: Verbose code and Numeric code.

The 56-kbps FastPath chipsets provide direct access to the internal registers known as S-registers. The DTE uses S-registers to set up and check modem configurations. The contents of these registers can be changed using the ATSn=x command, where 'n' is the register number and 'x' is the value to be stored. The contents of the S-registers can be read using the ATSn? command. Most S-registers can be read from or written to; however, some S-registers (such as S14) are read-only. Writing to a read-only register may cause the modem to act improperly (that is, even though the contents of a read-only S-register may be changed using the ATSn=x command, changing the contents of the S-register does not normally configure the entire modem).

Reserved S-registers are used by the modem and provide no valuable information to the DTE. These registers should never be written to, as they cause the modem to lock up. A list of the supported S-registers follows.

[Dialing a Remote Modem]

Command Line: ATDP9WT002, (886)-1234567 <CR>

This command line instructs the modem to dial a remote modem through a PBX. The modem first uses pulse dialing to dial 9 (the access code of the PBX), waits for outside dial tone, and then uses touch tone dialing to dial 002 once a one-second continuous dial tone is detected within 30 seconds, pause for 2 seconds (if S8=2) and then dial 8861234567.

[Dial s Stored Number]

Command line: AT&Z2=T03, 123456<CR>

Command line: ATDS=2<CR>

The first command line stores the dial string T03, 123456 to the 3rd location in NVRAM. Afterward you can use the second command line to dial this stored number. The dial string T03, 123456 will appear on the screen to indicate the number being dialed.

[Manual Answer an Incoming Call]

Command line: ATA<CR>

The factory setting of the S-Register S0 is S0=0. This command disables the auto answer capability so that you must issue an ATA command to answer a call. At power up, your modem always monitors if there are incoming rings. If incoming rings are detected, your modem will display result codes on the screen as:

RING

RING

:

:

RING

Seeing that, you may issue the ATA command to answer the call. This command must be entered within the quiet interval between any two rings.

[Auto Answer an Incoming Call]

Command line: ATS0=2 &W &Y <CR>

Auto answer can be enabled by changing the setting of the S-Register S0 to a value between 1 and 255. In the above command line, S0=2 instructs the modem to answer an incoming call automatically after the 2nd ring. The &W command writes this configuration to profile 0 in NVRAM. &Y command instructs the modem to load profile 0 as the active configuration on power-up. The last two commands make S0=2 the default value at power-up or reset. This example also shows the insertion of space between two neighboring commands to make the command line more readable.

[Force V.42 bis data compression with LAP-M error correction]

Command line: AT\N4%C2-K0

[Force V.42 bis data compression with MNP error correction]

Command line: AT\N5%C2

[Force MNP 5 data compression with MNP error correction]

Command line: AT\N5%C1

If the remote is unable to negotiate the desire rate mode, the modem will disconnected and respond with NO CARIER.

[Auto negotiate data compression and error correction]]]]

Command line: AT&F

or

Command line: AT\N3%C3

In this mode, the modem prefers LAP-M over MNP 10, MNP 10 over MNP 4, and V.42 bis over MNP 5. If error correction is not negotiated, the modem will connect in normal mode.

This chapter describes common problems in the installation, configuration and regular usage of your Fax/Data Modem. To test the Fax/Data Modem, a communication software package is needed and the package must include a mode that allows you to operate your Fax/Modem by directly issuing internal commands to the modem.

Follow the procedures in the following sections to resolve these common problems:

[No Response From Your Modem]

1.Make sure that the COM port address you have set your modem to corresponds to the appropriate selection in the communications software which you are using.

3.Check if there are any other interface cards in your computer that use the same COM port address as your modem. If so, you must set your modem to another COM port address. (Keep in mind that on most systems, only two COM port are available. One of them must be used as either 1 or 3, while the other must be used as 2 or 4.) For example, if a mouse is set to COM 1, your modem should be set to COM2 or COM4. Continue to the next step if the COM port address is OK.

[Your Modem Does Not Dial Out]

Make sure that your modem responds normally as described in section 6.1. If you can communicate through the keyboard, check whether the modem is properly connected to the phone line.

[Your Modem Does Not Connect After It Has Dialed a Phone Number]

[You Can Not Transmit After You Have Connected to the Remote Modem]

In this case, check the communication parameters of the remote modem, then configure your software to the same number of data bits, stop bit, and parity.

[Finding the Source of Transmission Errors]

A failure in modem communication is usually characterized by unacceptable high error rates or a total inability to communicational it may be the fault of the local computer or terminal, the local modem, the telephone line, the remote modem or terminal.

This V.90 56Kbps Fax/Modem PC card offers the capability of firmware upgrade for the users. Use the download program provided in the driver disk, one can easily upgrade the new firmware into the flash memory in our Fax/Modem card.
