    last reset.The alarm condition declared when a
    device receives no signal or cannot
    synchronize to the signal being received.  A
    Red Alarm is generated if the incoming
    data stream has no transitions for 176
    consecutive pulse positions.

    MultiVoip Program Menu Items
       After the MultiVoip program is installed on the PC, it can be launched
    from the  Programs group of the Windows Start menu ( Start |
    Programs | MultiVOIP ____ | … ).  In this section, we describe the
    software functions available on this menu.
    Several basic software functions are accessible from the MultiVoip
    software menu, as shown below.
    MultiVOIP Program Menu
    Menu Selection Description
    Configuration Select this to enter the  Configuration
    program where values for IP,
    telephony, and other parameters are
    set.
    Date and Time Setup Select this for access to set
    calendar/clock used for data logging.
    Download CAS ProtocolTelephony CAS  files are for Channel
    Associated Signalling.  There are many
    CAS files, some labeled for specific
    functionality, others for countries or
    regions where certain telephony attributes
    are standard.

    MultiVOIP Program Menu (cont’d)
    Menu Selection Description
    Download Factory Defaults Select this to return the configuration
    parameters to the original factory
    values.
    Download Firmware Select this to download new versions
    of firmware as enhancements become
    available.
    Download User Defaults To be used after a full set of parameter
    values, values specified by the user,
    have  been saved (using Save Setup).
    This command loads the saved user
    defaults into the MultiVOIP.
    Set Password Select this to create a password for
    access to the MultiVOIP software
    programs (Program group commands,
    Windows GUI, web browser GUI, &
    FTP server).  Only the FTP Server
    function requires a password for access.
    The FTP Server function also requires
    that a UserName be established along
    with the password.
    Uninstall Select this to uninstall the MultiVOIP
    software (most, but not all components
    are removed from computer when this
    command is invoked).
    Upgrade Software Loads firmware (including H.323
    stack) and factory default settings from
    the controller PC to the MultiVOIP
    unit.
    “Downloading” here refers to transferring program files from the PC to
    the nonvolatile “flash” memory of the MultiVOIP.  Such transfers are
    made via the PC’s serial port.  This can be understood as a “download”
    from the perspective of the MultiVOIP unit.
    When new versions of the MultiVoip software become available, they
    will be posted on MultiTech’s web or FTP sites.  Although transferring
    updated program files from the MultiTech web/FTP site to the user’s
    PC can generally be considered a download (from the perspective of
    the PC), this type of download cannot be initiated from the MultiVoip
    software’s Program menu command set. 
    						
    							MultiVOIP User Guide Operation and Maintenance
    349
    Generally, updated firmware must be downloaded from the MultiTech
    web/FTP site to the PC before it can be loaded from the PC to the
    MultiVOIP.
    Date and Time Setup
    The dialog box below allows you to set the time and date indicators of
    the MultiVOIP system.
    Obtaining Updated Firmware
    Generally, updated firmware must be  downloaded from the MultiTech
    web/FTP site to the  user’s PC before it can be downloaded from that
    PC to the MultiVOIP.
    Note that the structure of the MultiTech web/FTP site may change
    without notice.  However, firmware updates can generally be found
    using standard web techniques.  For example, you can access updated
    firmware by doing a search or by clicking on Support. 
    						
    							Operation and Maintenance MultiVOIP User Guide

    If you conduct a search, for example, on the word “MultiVoip,” you
    will be directed to a list of firmware that can be downloaded.
    If you choose Support, you can select “MultiVoip” in the Product
    Support menu and then click on Firmware to find MultiVOIP
    resources.
