  • Page 32: Introduction

    ModemModule Developer’s Guide Introduction The Service Class 1 standard (EIA/TIA-578) defines the commands that a PC user may issue to configure and control a fax/data modem, and the responses (result codes) that the fax/data modem may issue in response to those commands. The Class 1 standard provides the basic services needed to support Group 3 fax operation.

    ModemModule User Guide Introduction Remote configuration is a network management tool that allows you to configure modems anywhere in your network from one location. With password-protected remote configuration, you can issue AT commands to a remote MT3334SMI for maintenance or troubleshooting as if you were on-site. Basic Procedure The following steps are valid regardless of whether the connection is established by the local or the remote Multi-Tech modem.

  • Page 56: Introduction

    ModemModule Developer’s Guide Introduction Each time you turn on your modem, it performs an automatic self-test to ensure proper operation. Your modem also has three diagnostic tests: local analog loopback, remote digital loopback, and local digital loopback. These ITU-T V.54 loopback tests isolate telephone circuit and transmission problems.

  • Page 57: Remote Digital Loopback Test (V.54 Loop 2)

    6. Your modem passes this test if the data received on your monitor are the same as the data entered from your keyboard. If different data appear on your monitor, your modem is probably causing the problem, though it could also be your computer. If your modem passes this test, but you are receiving errors while on line, the remote modem or the phone line could be at fault.

  • Page 58: Local Digital Loopback Test (V.54 Loop 2)

    ModemModule Developer’s Guide Local Digital Loopback Test (V.54 Loop 2) The local digital loopback test is identical to the remote digital loopback test with one exception. Instead of using your modem to signal a remote modem to place itself in digital loopback mode, your modem is placed in digital loopback mode while the remote modem is not.

  • Page 60: Introduction

    ModemModule Developer’s Guide Introduction Your ModemModule is controlled by semi-permanent firmware that is stored in flash memory. Firmware is nonvolatile; it remains stored in memory when the modem is turned off. However, it can be changed by either the manufacturer or the user as bugs are fixed or new features are added. Since the firmware is stored in flash memory, you can upgrade it yourself in a few minutes by using the following procedures.
