Introduction analog calls are detected, they are automatically connected to one of the four V.90 modems on the ISIHP board. In this way, these hybrid cards can handle either ISDN calls or analog modem calls. Although the ISIHP-2S/2U contains four ISDN TA ports and four analog modem ports, only four ports can be active at any one time (because only four B-channels are present). See Figure 1-1. The ISIHP-4S/4U works like the ISIHP-2S/2U but contains four terminal adapters and eight V.90/K56flex modems.

Modem AT Commands & S-Registers Modem AT Commands ISIHP modems are controlled by instructions called AT commands, so called because the attention characters, AT, precede each command or sequence of commands (known as a command string). You can send commands to the modem from your keyboard while in terminal mode, or you can use communications software to issue these commands automatically. The modem is in command mode when it is not dialing or online.
Modem AT Commands & S-Registers mode without losing the carrier signal. While waiting to establish the carrier, you can type any character from the keyboard to make the modem to go back to the command mode. Command Structure You can control a wide variety of modem operations and options when the modem is in command mode. AT commands tell the modem to dial a number, to answer a call, to operate at a certain speed, to use a certain compression technique, and many other functions.
Modem AT Commands & S-Registers string. The AT command is not executed until you press ENTER. Use the BACKSPACE key to erase the previous command character. It will not erase the AT characters once they are typed. If your keyboard has no BACKSPACE key, use CTRL+H. (You can change the character recognized by the modem as BACKSPACE to any other ASCII character by changing register S5.) Press CTRL+X to cancel an entire command that has been typed but not yet executed. This also clears the command buffer.

Modem AT Commands & S-Registers O Go back online Dialing Commands Use dialing commands to dial and hang up. Ds Dial s = phone number Default: none Causes the modem to dial the telephone number immediately following it. For example, if you type ATD5551212, the modem dials the number 555-1212. Hn On-Hook/Off-Hook n = 0 or 1 Default: 0 Makes the modem hang up (go on-hook) or simulate the action of picking up a telephone handset (go off-hook).
Modem AT Commands & S-Registers ! $ @ ^ Flash On-Hook Detect Call Card Tone Quiet Answer Disable Data Calling Tone Transmission Phone Number Memory Commands ISIHP modems can store up to four telephone numbers in nonvolatile memory. You can store the numbers with the &Z command and dial them with the ATDS command. &Zn=s Store a Phone Number s = phone number n= 0, 1, 2 or 3 Default: none You can store a telephone number string in the modems phone number memory.
Modem AT Commands & S-Registers &Wn Store Configuration n=0 Default: &W0 The &W command stores current AT commands and S-register values in nonvolatile memory, so you wont lose your custom settings when you turn off the modem or reset it. &W0 (or &W) stores all current AT command and S-register values in nonvolatile random access memory (NVRAM) and configures the modem so it reads your custom settings in NVRAM when the modem is turned on or when it is reset with the Z command.
Modem AT Commands & S-Registers &Y0 selects the profile stored at location 0 on power-up. Modem Response (Result Code) Commands ISIHP modems can give responses to commands. The most common is OK, but the modems also can alert you or your software to dial tones, busy signals, connection speeds, and whether the connection is made with error correction or compression enabled. These responses are called result codes; they can be terse (numbers) or verbose (text).
Modem AT Commands & S-Registers V0 (or V) displays the modems result codes as a number. V1 displays result codes as text. V2, an additional command given anytime after ATV1 is entered, displays the connect message of both the local modem and the remote modem. Xn Result Codes and Call Progress Selection n = 0, 1, 2, 3, 4, 5, 6, or 7 Default: X4 Selects which result codes the modem provides in command mode and determines whether the modem uses smart dialing or blind dialing.
Modem AT Commands & S-Registers with NO DIALTONE or BUSY, as appropriate. It also provides extended result codes. It is the most useful setting for most data communication programs and is the default setting. X6 causes the modem to look for a dial tone and a busy signal and respond with NO DIALTONE or BUSY, as appropriate. It also provides extended result codes. It is the most useful setting for most data communication programs and is the default setting.
Modem AT Commands & S-Registers initiating the handshake between the two modems.) At higher speeds (2400 bps and above) there is no conflict because all protocols use the Bell frequency of 2225 Hz. Lower speeds require different frequencies. B0 selects ITU-T V.22 mode when the modem is at 1200 bps. B1 selects Bell 212A when the modem is at 1200 bps. This is a default. B15 selects V.21 when the modem is at 300 bps. B16 selects Bell 103J when the modem is at 300 bps. This is a default.
Modem AT Commands & S-Registers Nn Modulation Handshake n = 0 or 1 Default: N1 Controls whether the local modem performs a negotiated handshake with the remote modem at connection time when the communication speed of the two modems is different. N0 enables handshaking only at the communication standard specified by S37 and the ATB command. N1 always begins the handshake only at the communication standard specified by S37 and the ATB command, but allows fallback to a lower speed as the handshake proceeds.
Modem AT Commands & S-Registers Default: &C1 Allows you to control the Carrier Detect (CD) signal on the RS-232/V.24 interface. This is a signal from the modem to your computer indicating that the carrier signal is being received from a remote modem. Normally, CD goes high (turns on) when the modem detects a carrier on the communications link and drops (turns off) when it loses the carrier. By using &C, you can force the signal to stay high, or to drop momentarily when the remote modem disconnects.
Modem AT Commands & S-Registers &Sn Data Set Ready Control n = 0 or 1 Default: &S0 Controls the state of the Data Set Ready (DSR) signal on the RS-232/V.24 interface. Normally, DSR follows CD. You can force the signal high or allow it to act normally. &S0 forces DSR high (on). &S1 allows DSR to act normally, that is, to follow CD. Error Correction and Data Compression Commands You can configure modems to any of three different V.
Modem AT Commands & S-Registers must be connected to a modem with a V.42 protocol (MNP or LAP-M). The V.42 standard includes MNP Class 3 and 4 and LAP-M error correction methods. \N5 enables auto-reliable mode. During the handshaking procedures at the start of the online connection, the modem queries whether the other modem is using V.42 error correction. If the modem determines that the other modem is using V.42, it switches itself into reliable (V.42) mode and enables error correction.
Modem AT Commands & S-Registers n=0 Default: none This command displays specific product information about your modem. I0 or I returns the controller firmware version number. Use this command to identify your modems firmware level before calling Multi-Tech Technical Support. (Same as I3.) &Bn &V Default: none Dummy command View Current Configuration Use the &V command to display the active modem settings.
Modem AT Commands & S-Registers &K4 enables XON/XOFF software flow control. XON/XOFF flow control is an in-band method of data flow regulation. In-band data regulation means that the XON (^Q) and XOFF (^S) characters are inserted into the stream of data rather than using separate control lines. When an XOFF character is detected, the data stream is suspended until an XON character is detected.
Modem AT Commands & S-Registers which uses the Request to Send (RTS) signal on the RS-232/V.24 interface. Hardware flow control cannot be enabled unless an active error correction protocol is selected. This is the factory default setting. (This is the same as &K3.) \Xn XON/XOFF Pass-Through n = 0, 1 Default: \X0 When XON/XOFF pacing is active, the local modem has two options regarding the XON and XOFF characters.
Modem AT Commands & S-Registers the modem to enter command mode from online mode without disconnecting the call. +++AT In-Band Escape Sequence If the modem is online with a remote modem, you can cause the modem to enter command mode without disconnecting the call by typing an escape code. The default escape code used by the modem is three plus signs (+++) followed by the letters AT, up to 10 command characters (most typically H, to hang up), and ENTER.
Modem AT Commands & S-Registers Modem S-Registers S-registers are small regions of memory where modem configuration information is stored. Whereas AT commands tell a modem what to do, Sregisters tell the modem how to do it. Each S-register has a name that consists of the letter S and a number (S0, S1, S2, etc.), hence the term Sregister. Use the Sr? command to read the value stored in an S-register and the Sr=n command to change it.
Modem AT Commands & S-Registers Setting an S2 value greater than 127 results in no escape character, resulting in no means of entering command mode from online mode without breaking the online connection unless you use the BREAK method. Note: If you change the S2 value, you must make corresponding changes in your data communications software. S3 Return Character Unit: Decimal Range: 0127 Default: 13 (^M) Defines carriage return character by its decimal ASCII code.
Modem AT Commands & S-Registers S6 Wait Time for Dial Tone Unit: 1 second Range: 265 (North America), 4255 (International), 47 (U.K.) Default: 2 (North America), 4 (International and U.K.) Defines length of time the modem waits after ENTER is pressed before carrying out a dial command. Default setting is two seconds for North America, four seconds elsewhere.
Modem AT Commands & S-Registers S10 Carrier Loss Disconnect Delay Time Unit: 100 ms Range: 1254 Default: 20 Defines the length of time, in milliseconds, that the modem waits after a loss of carrier signal before the it disconnects. The default setting is 2000 ms (20 units of 100 ms each). Maximum delay is 25400 milliseconds, or 25.4 seconds (decimal 254).
Modem AT Commands & S-Registers S37 Maximum Dial Line Rate Unit: decimal Range: 019 Default: 0 Sets the maximum dial line rate. When set to zero (0), the maximum dial line rate is the same as the maximum modem speed. This is the most common setting and allows other modem functions to actually determine the line rate used for each connection. It is the default. Consider using S37 to set a maximum dial line rate if you need to artificially retain a lower modem speed.
Modem AT Commands & S-Registers Range: 0-1 Default: 1 (enabled) Used for testing and debugging only. Enables and disables V.32bis start-up auto mode operation. Set S43 to zero (0) to disable start-up auto mode, or 1 (the default) to enable start-up auto mode. S89 Off-line Time Unit: 1 second Range: 0, 5-255 Default: 0 Sets the length of time, in seconds, a modem waits in the off-line command mode before it goes into standby mode.
Modem AT Commands & S-Registers Reading and Assigning S-Register Values Use the S command to assign a value to an S-register and to read an its current value. To read an S-register value, in terminal mode, type S, the Sregister number, and a question mark (?), and press ENTER. For example, to display the value of register S7, type ATS7? and press ENTER. The value appears as a three-digit decimal number (e.g., 045).
Modem AT Commands & S-Registers verification read command in the same command string as the configuration assignment command. In the three preceding examples, type ATS8=5S8?, ATS0=4S3?, and ATS7=75S7?, respectively. AT Commands that Affect S-Registers For maximum throughput, the ISIHPs default configuration is for originating a call to another 33,600 bps modem that supports error correction, data compression, and flow control.
Modem AT Commands & S-Registers 4 ERROR Error in command line (too many, or invalid characters). 5 CONNECT 1200 Modem detected carrier at 1200 bps and gone online. 6 NO DIALTONE No dial tone detected. 7 BUSY Busy signal detected. 8 NO ANSWER The remote system did not answer. 10 CONNECT 2400 Modem detected carrier at 2400 bps and gone online. 11 CONNECT 4800 Modem detected carrier at 4800 bps and gone online. 12 CONNECT 9600 Modem detected carrier at 9600 bps and gone online.

RETURN Command Execution Values: n/a Default: n/a Press the RETURN (ENTER) key to carry out a command. The RETURN key is sometimes abbreviated in command examples.
Terminal Adapter AT Commands & S-Registers Standardized ISDN signalling protocols such as DSS1, DSS2, and SS7 support sending complete indication, a signal that no more digits will follow. Adding such a signal to a telephone number is often impractical; therefore, many private networks send the number of a called party using a procedure called overlap sending, in which no sending complete indication is sent.
Terminal Adapter AT Commands & S-Registers Values: n = 0- to 20-character string Default: null string Specifies the channel 1 service profile identifier (SPID) that the ISDN service provider assigned at subscription time. The voice SPID string can have up to 20 characters. Note: For DMS-100 switches, any ASCII character except the underline (_) character is valid. For NI-1 and AT&T switches, only the digits 09 are valid. (Not needed for NET3 switch type.
Terminal Adapter AT Commands & S-Registers *!D3=0-63 Sets the TEI to a fixed value from 0 through 63 *!D3=240 Sets voice channel for dynamic TEI negotiation (factory default) *!D3=241 Disables TEI !L Display Network Configuration Values: n/a Default: n/a Displays the current DN, SPID, TEI, Data protocol, and switch type.
Terminal Adapter AT Commands & S-Registers !N1=n DN0 Sets the Data Directory Number /Multiple Subscriber Number (DN/MSN) for data ports 1 and 2. The DN/MSN is a number assigned to the BRI at subscription time by the ISDN service provider. The DN/MSN is a string of up to 25 characters; valid characters are 0-9, the * character, and the # character. If used as an MSN, a subaddress can be added to the number (if one is needed) by using the : character followed by the subaddress number.
Terminal Adapter AT Commands & S-Registers originate data calls. This is useful for applications where a specific port is for dial-out only. Usage: !ENn Function: Enable Data DN/MSN n Values: n=1 (enable Data DN/MSN 1), n=2 (enable Data DN/MSN 2) Default: All ports are enabled by default Description: !ENn enables a Data DN/MSN which will put it back in service for accepting and originating data calls.
Terminal Adapter AT Commands & S-Registers same value as Data DN/MSN 1 and/or 2. A call accepted by Modem DN/MSN 2 will be routed to the second modem. Usage: *!DNn Function: Disable Modem DN/MSN n Values: n=1 (disable Modem DN/MSN 1), n=2 (disable Modem DN/MSN 2) Default: All ports are enabled by default Description: *!DNn disables a Modem DN/MSN which will effectively disable the associated modem port from receiving any modem calls. However, the port will still be able to originate modem calls.
Terminal Adapter AT Commands & S-Registers Serial Port Configuration Commands Use the following commands to control the interaction between the TA and the computer connected to it. En Command Mode Echo Values: n = 0 or 1 Default: E1 (Echo on) When you enter commands, the TA echoes the characters back to the computer or terminal where they appear on the monitor. This command turns this feature on and off.
Terminal Adapter AT Commands & S-Registers Sets the value of an S-register, where r is the number of the S-register, and n is the value you want to set. Sr? Read S-Register Values: r = 05 (S1 is read only) , 7, 8, 10, 25, 32, 34, 50, 52-57, 75-77, 80; n varies Default: None Reads the value of an S-register, where r is the number of the S-register. Vn Terse/Verbose Result Codes Values: n = 0 or 1 Default: V1 (Verbose) Controls whether the TAs result codes display as digits (terse) or as words (verbose).
Terminal Adapter AT Commands & S-Registers X5 Enables printing Calling Line Identification (CLI) at the end of the CONNECT message line. This command does not affect X0, X1, nor X2. Z Reset to Stored Profile Values: none Default: none Resets TA to its current power-up profile and clears the command buffer. The result is the same as turning the TA off and on. When you type ATZ, the state of the &W command determines where default values originate.
Terminal Adapter AT Commands & S-Registers Controls how the TA responds to the DTR (Data Terminal Ready) signal. A high DTR signal tells the TA that the connected computer is ready to communicate. &D0 TA ignores the DTR signal. &D1 If DTR lowers when the TA is online, TA hangs up, returns to command mode, and disables autoanswer. If the TA is offline, it doesnt answer or dial while DTR is low. &D3 When DTR lowers, the TA resets the data port and disables autoanswer.
Terminal Adapter AT Commands & S-Registers Selects method by which the TA controls the flow of data to and from the computer, to prevent either device from accepting data faster than it can handle. The TA provides flow control in both directions. When the TA halts data flow, it is called flow control; when the computer halts data flow, it is called pacing. &E3 Disable flow control by the TA. &E4 Hardware flow control. &E4 causes the TA to use the CTS signal to regulate flow control.
Terminal Adapter AT Commands & S-Registers #Xn Send Single/Multiple Xoff Characters Values: n = 0 or 1 Default: #X0 Allows the TA to send either a single or multiple Xoff characters to exert flow control to the terminal. The #X0 command (factory default setting) causes one Xoff to be sent until the TAs buffer reaches the Xon level. The #X1 command causes an Xoff to be sent for every character received after the TA reaches its buffer full level.
Terminal Adapter AT Commands & S-Registers Allows you to control the state of the CTS (Clear to Send) signal. Normally the CTS signal follows the state of the RTS signal when TA is online. &R0 CTS acts normally; that is, it follows RTS. &R1 CTS is forced high, but still provides online flow control. &R2 CTS is forced high, but it drops on disconnect for the period of time set by S10. CTS still provides flow control when the TA is online.
Terminal Adapter AT Commands & S-Registers &Wn Store Active Profile Values: n = 0 or 1 Default: &W1 (Use factory default profile) Stores your active profile, or configuration, in memory, so you dont lose your custom settings when you turn off the TA or reset it. &Zn=x &W0 Stores all current AT command and Sregister values in nonvolatile random access memory (NVRAM) and configures the TA so it reads your custom settings in NVRAM when the modem is turned on or when it is reset with the Z command.
Terminal Adapter AT Commands & S-Registers 6 4258513 7 8 16126313550 9 12138880123 DSn Dialing a Stored Telephone Number Values: n = 09 Default: n/a To dial a stored telephone number, type ATDSn in terminal mode, where n is the location of the number you want to dial. For example, typing ATDS6 dials a telephone stored in memory register 6 location. $Dn Persistent DTR Dialing Values: n = 0, or 1 Default: $D0 (Disabled) Enables or disables persistent DTR dialing (PDD).
Terminal Adapter AT Commands & S-Registers to +++ %E3 %E5 Enable +++ or method and OK response to +++ @P3=n Parity at Power-Up Values: n = 04 Default: @P3=4 (None) Use only to set the type of parity the TA uses when turned on. Once the TA receives an AT command from the computer, it automatically adjusts to parity the computer is using.
Terminal Adapter AT Commands & S-Registers Data Call Commands Use these commands to make or configure data calls. A Answer Call Values: none Default: none Forces TA to answer an incoming call. To cause the TA to autoanswer, set register S0 to a value higher than 0. Dn Dial Values: string of up to 25 characters Default: none Causes TA to dial a telephone number (e.g., ATD785-3500 ).
Terminal Adapter AT Commands & S-Registers Returns TA to online mode from the online command mode. When TA makes a data connection, it enters online data mode. The TA typically remains in this mode until it receives an escape sequence or until the call ends. When it detects an escape sequence, the TA enters online command mode, where it can accept AT commands while retaining the online connection. To return the TA to online mode from the online command mode, enter the command ATO and press ENTER.

The S25 unit value for 0 is 40 ms. For values from 1 through 255, the unit value is 100 ms.
Terminal Adapter AT Commands & S-Registers S34 Maximum Escape Sequence Length Unit: Decimal ASCII code Range: 010 Default: 2 Sets the maximum character length of the escape sequence, not including +++AT. For example, a character length of S34=2 allows two characters after +++AT (e.g., +++ATH0). Conversely, an invalid escape sequence (too many characters placed in the command string) passes through as data (e.g., +++atili2). The maximum length of the escape sequence is 10 characters.
Terminal Adapter AT Commands & S-Registers Range: n=0Disable, n=1Detect, n=2Detect and Select Default: 1 (Detect) Enables or disables the ability to identify the reception of V.110, V.120, X.75, or PPP data calls. The TA determines the type of call by checking for protocol information in the SETUP message or by matching protocol information received on the B-channel once connected if no protocol information is available in the SETUP message.
Terminal Adapter AT Commands & S-Registers speech call originated on that line. However, 3.1 kHz audio information transfer capability is allowed on data lines (modem or fax) by most switches. S55 also lets you define whether a progress indicator information element (which indicates that the origination address of the POTS call is non-ISDN) is sent with the SETUP message for the POTS port call. This may help POTS port calls get through certain CO switches. S1 Speech, no progress indicator S2 3.

Terminal Adapter AT Commands & S-Registers computer and responds to AT commands. There is no data communications link with a remote device. Data Mode The TA enters data mode when it makes a successful data communications link with a remote device. In data mode, the TA can send and receive data, but it does not respond to AT commands. Instead, it treats them as data, and transmits them to the remote device.
Terminal Adapter AT Commands & S-Registers Canceling a Call To cancel a call before the TA makes a connection, press any key. Storing a Telephone Number To store a telephone number, type &Zn=x in terminal mode, where n is the number of the memory register in which the number is to be stored, and x is the dial command string that you want to store. For example, type AT&Z9=612785-3500 to store the number 612-785-3500 in memory register 9.
Terminal Adapter AT Commands & S-Registers of rings. 2. Make sure that the TA is offline. The TA answers the call after the number of rings specified by S0. To disable autoanswer, use a configuration utility or the command S0=0. Note: If the user wants to accept calls while DTR is low, the TA must be configured to ignore DTR. To ignore, enter AT&D0. With this configuration, the TA can accept calls while DTR is low.

Troubleshooting Troubleshooting MultiModemISI Hybrid Series, ISIHP-2S/2U/4S/4U/4SD 141
Troubleshooting This chapter covers common problems you may have with your ISIHP and how to solve them. The ISIHP was thoroughly tested at the factory before shipping. If you are unable to connect successfully, or if you experience data loss or garbled characters, during connecting, it is possible the modem or terminal adapter is defective. However, it is more likely that the source of your problem lies elsewhere. Always make sure all hardware is connected properly.
Troubleshooting disconnect without ending the program (make sure the Connect icon looks plugged in). MultiExpress Terminal also allows multiple terminals to be open, but only one can access the modem/TA at a time. Your communications software settings may not match the physical port where the TA is connected. The serial cable may be plugged into the wrong connectorcheck your computer documentation to make sure.
Troubleshooting other device. Or, select the port the conflicting device is on and change it instead. If you need to open your computer to change switches or jumpers on the conflicting device, refer to the your computers documentation. The serial port may be defective. If you have another serial port, install the TA on it, change the COM port setting in your software, and try again. The TA may be defective. Call Tech Support for assistance (see Chapter 6).
Troubleshooting call (see Chapter 3). You can place data calls but not voice calls, or vice versa You might not have ordered both voice and data service from your ISDN provider. Check your contract or latest statement of service from your ISDN provider. Your ISDN provider may have programmed the switch incorrectly. Call the provider. You cannot place two simultaneous data calls You may not have ordered an ISDN line configuration that supports two simultaneous calls.
Troubleshooting time limit for the day. Try again. The terminal adapter cannot connect when answering Autoanswer may be disabled. Turn on autoanswer in your data communications program, or send the command ATS0=1 to your TA in terminal mode. Note: To accept calls while DTR is low, configure the TA to ignore DTR by entering AT&D0. Configured this way, the TA accepts calls while DTR is low. Otherwise the TA rejects incoming calls until DTR is high while the calls come in.
