You must enter the command while in your communication program’s terminal mode.
Chapter 4 - AT Commands, S-Registers and Result Codes S-Registers S-registers are sections of memory in which values are stored that affect how the MTA128STUSB operates. S-registers are so-called because each has a name that begins with the character S. Use the S command to assign a value or to read the current value of an S-register. To assign a value to an S-register, use the command Sr=n, where r is the register number, and n is the value you want to assign, e.g., S7=45.
MultiModemISDN User Guide S-Register: S0 Function: Number of Rings Until Answer Unit: 1 ring Range: 0–255 Default: 1 Description:Sets the number of rings the TA waits for before it answers and begins its connect sequence. S0=0 turns off the ability to automatically answer a call. S0=1 causes the TA to automatically answer after 1 ring. If the S0 value is set too high, the calling device may time out before the TA answers the call.
Chapter 4 - AT Commands, S-Registers and Result Codes S-Register: S7 Function: Wait for Connection (Abort Timer) Unit: 1 second Range: 0–255 Default: 45 Description:Sets the Abort Timer delay time, which is the length of time the TA waits for a connection after dialing. If no connection is established during the specified time, the TA ends the call.
MultiModemISDN User Guide S-register: Function: Unit: Range: S30 On-line Inactivity Timer 1 minute n=0 Does not disconnect n=1–255 Default: 0 (does not disconnect) Description:Makes the TA disconnect a data connection if no data is transmitted or received for the specified time. It will NOT cause a POTS call (voice/modem/ fax) to disconnect. The timer restarts any time a data character passes through the serial port (either sent or received).

MultiModemISDN User Guide complete. The PPP Magic-Number Block contains 5 Magic-Numbers in this implementation and is the default type. The Public Switched Network Directory Number option uses Data Directory Number 1 as the Endpoint Discriminator (if it is blank, then Endpoint Discriminator is blank). The Locally Assigned Address (S73=1), IP Address (S73=2), and IEEE 802.
Chapter 4 - AT Commands, S-Registers and Result Codes Auto-synchronizing allows the TA to adapt to the client’s network rate without any need for the host to have its network rate predetermined. If S77=2 and a V.110 call is originated, then the network rate will be that of S76 ($MB).
MultiModemISDN User Guide Using AT Commands to Operate the MTA128ST-USB You can configure and operate the MTA128ST-USB entirely with AT commands if you like. But remember, you can issue AT commands only from a terminal or from a computer running a communications program in terminal mode. This section describes how to use AT commands for basic operations, such as calling, answering a call, and hanging up. Modes of Operation The MTA128ST-USB has three modes of operation.
Chapter 4 - AT Commands, S-Registers and Result Codes Channel Bundling Flag Dialing The command AT&Jn is used to indicate whether outgoing calls should be made on two B-channels by default. The command AT&J1&W0, configures the TA to place a call, dialing on two B-channels by default. If no second number is given in the dial string, that single number is dialed twice. This compensates for the interworking issues with Windows 95.
MultiModemISDN User Guide Answering a Call You can answer incoming calls to the TA either manually or automatically. When the TA detects an incoming call, it sends a RING result code to the computer or terminal after each ring. If autoanswer is enabled, the TA automatically answers the call. You can manually answer the call with the A command. Both methods are described below.
Chapter 5 - Troubleshooting
MultiModemISDN User Guide Introduction This chapter describes basic problems you may run into with your MTA128ST-USB and how to solve them. Your MTA128ST-USB was thoroughly tested at the factory before it was shipped. If you are unable to make a successful connection, or if you experience data loss during your connection, it is possible that the MTA128ST-USB is defective. However, it is more likely that the source of your problem lies elsewhere.
Chapter 5 - Troubleshooting The MTA128ST-USB does not respond to commands • Make sure the MTA128ST-USB is plugged in and turned on. (See None of the LEDs Light When the MTA128ST-USB Is On.) • Try resetting your MTA128ST-USB by turning it off and on. • Make sure you are issuing the MTA128ST-USB commands from the data communications software, either automatically, or manually in terminal mode. (You cannot send commands to the MTA128ST-USB from the DOS prompt.
MultiModemISDN User Guide • The MTA128ST-USB may be defective. If you have another Multi-Tech MTA128STUSB, try swapping units. If the problem goes away, the first MTA128ST-USB is possibly defective. Call Tech Support for assistance (see Chapter 6). The MTA128ST-USB dials but cannot make a connection There may be several reasons the MTA128ST-USB fails to make a connection. Possibilities include • Lack of a proper physical connection to the communication line. • A busy signal. • A wrong number.
Chapter 5 - Troubleshooting You cannot place two simultaneous data calls • You may not have ordered an ISDN line configuration that supports two simultaneous calls. Check your contract or latest statement of service from your ISDN provider. Also, your ISDN provider may have programmed the switch incorrectly. Call the provider. • You may have misconfigured your MTA128ST-USB to dial two simultaneous data calls.
MultiModemISDN User Guide Data is being lost • USB cable is not plugged in. • Make sure the flow control method you selected in software matches the method selected in the MTA128ST-USB. Making a V.120 call, caller gets a NO CARRIER message after dialing the number Some switches don’t support ISDN SETUP messages that contain a LLC (low layer compatibility) element. When these switches receive an LLC in the SETUP, they immediately reject the call and a NO CARRIER message displays. Disable LLC for V.
Chapter 5 - Troubleshooting MTA128ST-USB receives garbage characters when connected to a 3Com Impact IQ terminal adapter Most likely, the Impact IQ has compression turned on. The compression used by the Impact IQ is incompatible with the compression used by the MTA128ST-USB. Disconnect the data connection and give the Impact IQ the command AT%CO and then establish the data connection again. The garbage characters should disappear.

Also known as a device driver. DTE (data terminating equipment)—A term used to include any device in a network which generates, stores or displays user information. DTE is a telecommunications term that usually refers to PCs, terminals, printers, etc.
Glossary IRQ (interrupt request)—The notification a processor receives when another portion of the computer’s hardware requires its attention. IRQs are numbered so that the device issuing the IRQ can be identified, and so that IRQs can be prioritized. ISA (Industry Standards Architecture)—Pronounced ice-a. The classic 8- or 16-bit architecture introduced with IBM’s PC-AT computer.
MultiModemISDN User Guide O OHCI (OpenHCI): Open Host Controller Interface Specification for USB. All transfers on the USB are initiated by the host system’s host controller. The host controller is responsible for controlling traffic on the USB and can be appropriately programmed to transfer data to and from USB devices. This is typically a PCI device that can be programmed to run a given schedule of transfers on the USB and bus master the results into memory for processing by the host software.
Glossary reference point—A connection point between ISDN equipment classes (rather than the specific protocol of the interconnection). Can include R, S, T, and U reference points. RJ-11—An industry standard interface used for connecting a telephone to a modular wall outlet; comes in 4-and 6-wire packages. RJ-45—An 8-wire modular connector for voice and data circuits. RPOA (recognized private operating agency)—A corporation, private or government-controlled, that provides telecommunications services.
MultiModemISDN User Guide telecommunication service—A function, such as bearer service and teleservice, offered by an RPOA to its customer in order to satisfy a specific telecommunications requirement. See also ISDN, RPOA, and bearer service. telematics—User-oriented ISDN information transfer services (e.g., teletex, videotex, facsimile). Teleservices—A telecommunications service that provides the complete capability for communication between subscribers according to protocols agreed to by RPOAs.
Glossary V V.110—One of the terminal rate adaptation protocols for the ISDN B-channel. V.110 is more hardware-intensive than the V.120 B-channel standard. V.120—One of the terminal rate adaptation protocols for the ISDN B-channel. V.120 is more software-intensive than the V.110 B-channel standard. Videotex—A two-way information-retrieval service that can be accessed by terminals and by a TV set (with installed decoder). Allows interactive retrieval of information pages from a central resource.
