    Site Preparation
    This section describes how to prepare your site for a successful Syn248 system
    installation.

    Network Requirements


    A switched network topology is recommended for your LAN (using standard
    10/100 Ethernet switches that carry traffic at a nominal rate of 100 Mbit/s).



    The office LAN infrastructure should use Cat.-5 (or better) cable.



    The LAN connections to Syn248 devices should all be wired. However, wireless
    connections to other devices (such as laptops) in your office network that are not
    part of the Syn248 system will not impede performance.



    All devices in the Syn248 system must reside on a single subnet.



    A DHCP server is recommended and must be on the same subnet as the Syn248
    system so that IP addresses can be auto-assigned. In most cases, your network
    router will have a Dynamic Host Configuration Protocol (DHCP) server that will
    automatically assign IP addresses to Syn248 devices in the system. By default,
    Syn248 assumes that this automatic assignment will occur.
    If no DHCP server is present, you can assign static IPs. DHCP or static IPs are only
    required if the system is to be managed from a routable network and/or
    automatic time updates from an NTP server are desired. Syn248 devices will
    self-assign link-local IP addresses for all voice communication in addition to any
    DHCP or static IPs that are assigned for management purposes. For more
    information, see “Appendix B: IP Addresses and Connectivity” on page 104.

    Installation



    Unless you want to manually set the Syn248 clock and manually upgrade Syn248
    software, an Internet connection to the LAN is required.



    A DNS server is recommended to resolve the path to the Internet and to the AT&T
    server for software upgrades.



    If a routing path to the Internet is not available, the system administrator can
    download the upgrade files and use the WebUI to upgrade the software
    manually.



    For users whose computers require a GigE Ethernet frame rate (a gigabit per
    second), use separate Ethernet connections for the Deskset and the computer.
    The Ethernet connection through a Deskset is limited to 100 Mbits/s.

    11

    Back to Contents

    Placement Considerations
    Avoid placing any Syn248 component too close to the following:


    Communication devices, such as television sets, DVD players, or other cordless
    telephones



    Excessive heat sources



    Noise sources, such as a window with traffic outside, motors, microwave ovens,
    refrigerators, or fluorescent lighting



    Excessive dust sources, such as a workshop or garage



    Excessive moisture



    Extremely low temperature



    Mechanical vibration or shock, such as on top of the washing machine or
    workbench.

    Power Considerations
    Ensure that there is an electrical outlet not controlled by a wall switch within 6 feet
    (1.83 m) of each device location.
    SB35020 Desksets are also compatible with Power over Ethernet (PoE). To use PoE, your
    network needs a switch that provides PoE. Using PoE simplifies your installation by
    eliminating the need to route separate power cords. It also allows you to protect your
    system from power outages by connecting an Uninterruptible Power Supply (UPS) to your
    PoE switch and Gateway(s). For power requirement specifications, see “Appendix C:
    Technical Specifications” on page 105.

    Other Preparations
    Before installing the Gateway and Desksets, the following preparations may need to be
    taken:

    Installation



    All telephone lines must be gathered into one access point situated no more
    than 9 feet (2.74 m) from the Gateway location. If rewiring is required, contact
    your telephone service provider and request the help of a qualified technician.



    You may need one or more network switches set up to ensure there are sufficient
    ports available for other devices in the network (such as a DSL modem).



    If you plan to use the emergency bypass feature on the Gateway, you will need
    an analog phone.



    An Ethernet Port must be available within 9 feet (2.74 m) of each Deskset
    location. Each Deskset is capable of sharing an Ethernet port with a PC. If one
    Ethernet port already exists at a workstation, another port is not necessary
    unless you need a GigE Ethernet frame rate. If this is the case, use a separate
    Ethernet connection for the Deskset and the computer.

    Assigning Telephone Lines and Extensions
    This section discusses various telephone line configuration issues to consider.

    Providing Limited Telephone Service During AC Power Outages
    The fourth line on each Gateway is a Bypass port that works during AC power failures. If
    you have a telephone line plugged into LINE 4, connect a line-powered analog telephone
    to the RJ-11 jack labeled BYPASS for telephone service during power failures. When
    power returns and the line is idle, a relay disconnects this emergency bypass line so that
    the bypass line cannot be used to eavesdrop on normal calls.
    If your telephone lines are part of a hunt group (a telephone company feature that allows
    calls to a busy phone number to roll over to the next available telephone line), connect
    the line with your main (pilot) telephone number to Gateway LINE 4.

    Analog Line Connection Order on Gateways
    For outgoing calls, by default the system seizes the lowest idle LINE port numbers (as
    labeled on the Gateway) when users go off hook. You can also configure the automatic
    off-hook line selection for each extension (see “Extension Basic Settings” on page 47).
    If you plan not to change the default settings, telephone lines should be connected to
    your system with your busiest incoming line placed in the highest port number on the
    highest numbered Gateway (that is, Gateway #2 if you have the maximum two Gateways
    installed), so that incoming calls are less likely to receive busy signals. For instance, if
    your customer service team receives many calls, you would want to plug their phone
    lines into higher-numbered LINE ports.

    Connecting a Two-Line Wall Jack to the Gateway
    If you have two phone lines coming from one wall jack, you must use a two-line adapter
    (or A/B splitter) as shown in Figure 2 to convert the two-line jack into two single-line
    jacks. Each single-line jack will then connect to a Gateway LINE port.

    Extension Assignments
    The system assigns the first Deskset to join the network as extension 200. The system
    automatically assigns each additional Deskset an extension number in ascending order
    as it is connected to the LAN.
    Once the Desksets are connected to the same network, they find each other through
    Peer-to-Peer (P2P) discovery protocols and automatically self-configure. Additional
    telephony and network configuration is administered through the WebUI.
    Even if you disconnect a unit from the network, its extension number is reserved. If you
    want to remove an extension from the network permanently, you must disconnect it, then
    delete the extension number using the WebUI Device Management menu. Deletion
    ensures that the Deskset does not tie up an extension. You can also use the WebUI to
    change extension numbers for Desksets connected to the network.

    6.

    Insert a top mounting screw (not included) in one side and turn it several turns to
    establish support. Repeat for the other side.

    7.

    Tighten the screws.

    Wall Mounting
    You can mount the Gateway to a wall using the two mounting slots on the bottom of the
    device. Ensure that the device is oriented as shown in Figure 3 to allow air to flow
    vertically through the ventilation holes on each side of the device.

    Figure 3. Wall Mount Orientation

    To mount the Gateway to a wall:

    Installation

    1.

    Install two pan-head screws (with ¼-inch diameter head) 7 ⅞ inches (20 cm) apart.
    The screw shaft diameter should be ⅛-inch (3.2 mm). Ensure you use anchors
    appropriate for your mounting surface. Leave about ⅛-inch (3.2 mm) clearance
    between the screw head and the wall.

    2.

    Position the device with the mounting slot centers aligned over the mounting screws.
    Carefully bring the device down onto the screws.

    3.

    Slide the device downwards so that the screws go into the mounting slots on the
    device. Ensure the device is secure.

    If a GigE network is being used, a computer connected through the Deskset will
    be limited to 100 Mbits/s. If you require a GigE Ethernet rate, use separate
    Ethernet connections for the Deskset and the computer so that the computer can
    take advantage of the greater bandwidth.



    If a PC is connected to your LAN through a Deskset, any Deskset resets and
    power or network interruptions will disrupt the PC’s connection to the network.
    The PC port on the Deskset is intended for connection to an end-user PC only.

    Installation



    Do not use the PC port to connect to a PC with a heavy bandwidth load
    (such as a network server PC or a hub, switch, or router).



    Do not use the PC port to extend the network. The end-user PC should be
    the final point. Do not use the PC port to connect to other system devices.

    SYSTEM CONFIGURATION
    You can configure the Syn248 System using the WebUI. The WebUI consists of web pages
    with editable settings for the system and each Syn248 device. The WebUI is embedded
    in every SB35010 Gateway and SB35020 Deskset. When you access the WebUI, you are
    accessing it on the device, not on the Internet.
    This chapter shows you how to access and log in to the WebUI, then guides you through
    the settings you may have to configure to commission or to customize a Syn248 System.
    This chapter also covers device management using the WebUI. As the system
    administrator, you will use the WebUI to delete devices from the system, change
    extension numbers, back up your settings, and upgrade devices.
    After completing the configuration of the system, back up the system settings.
    See “Back Up and Restore Settings” on page 58.

    Logging in to the WebUI
    Only one person at a time should log in as the system administrator to
    prevent unintentional overwriting of changes.
    WebUI information for individual users is contained in the “Web Interface” chapter
    of the SB35020 Deskset User's Guide at www.telephones.att.com/smb.

    To access the browser interface and log in:
    1.

    Ensure your computer is connected to the same IP subnet as the Syn248 system. The
    easiest way to ensure this is to connect your PC to the PC port on the back of a
    Deskset with an Ethernet cable.

    2.

    On the Deskset, press MENU then 4. The Deskset Information screen appears.
    Note the IP Address.

    into which you type information. For your security, the WebUI times out after 10 minutes,
    so if it is idle for that time, you must log in again.
    The remaining procedures in this chapter assume that you are already logged in to the
    WebUI as administrator.
    In most cases there are multiple settings on one page. Changing a setting does
    not instantly apply the new value. Click

    operator. The default is Extension 200. The Operator can select the current Auto
    Attendant menu. See “Configuring the Auto Attendant” on page 33. As well,
    incoming external calls are forwarded to the operator extension if the caller presses
    0 (zero) after the Auto Attendant answers or when callers reach an extension’s
    voicemail. Deskset users can call the operator by pressing 0 from an active Intercom
    line.

    Set the Timer for Forwarded and Transferred Outside Calls. This sets the
    Maximum Call Duration for incoming calls when they are forwarded to non-system
    phone numbers, such as to cell phones. When you forward these calls, two phone
    lines are in use for the duration of the forwarded call — one for the incoming call
    and one for the call to the forwarded line — with no Syn248 user able to end the
    call. The default time is 30 minutes, adjustable from 15 to 120 minutes. Calls
    exceeding the Maximum Call Duration are dropped with no warning to the callers.

    5.

    Enable or disable Hook Flash system-wide. When enabled, Desksets have a Flash
    soft key available when an external line is active. Pressing Flash simulates a hook
    flash, which signals your telephone service provider to activate a feature. For
    example, hook flash may switch you to another incoming call when you hear a
    call-waiting tone, or enable you to create a conference call. These features may be
    offered as part of your phone plan. Features that use hook flash occur at the Central
    Office (CO) and are separate from any similar functions in Syn248.

    Configuring the Auto Attendant
    The Auto Attendant automatically answers unanswered external calls when it is set as a
    Call Foward–No Answer destination on the Phone Line CFNA page. See “Configuring
    Phone Line CFNA” on page 41. When calls are forwarded to the Auto Attendant, callers
    hear the Auto Attendant menu, which tells them how to use a touch-tone telephone to
    reach the appropriate person, operator, or extension mailbox.
    You can select one of three Auto Attendant menus from the Operator extension — the
    Default menu, a Day Menu, or a Night Menu. The default menu instructs callers to “Enter
    the extension number or enter 0 for the operator.”
    You can configure the Day Menu and Night Menu with your own voice greetings and
    key-press commands.

    Customizing the Auto Attendant Day and Night Menus
    Auto Attendant menus consist of the recordings that the callers hear and lists of actions
    they can take. To customize the Day and Night menus, plan what you want callers to be
    able to do. In preparation for recording, write down the greeting and instructions you
    want callers to hear when they reach each menu. See “Auto Attendant Voice Prompts”
    on page 36.

    Set Enable Direct Dial. Enabling Direct Dial allows callers to directly dial extensions
    by entering an extension number after reaching the Auto Attendant.
    If you assign dial key values that are the same as the first digit of any
    extension (2, for example), callers will be unable to directly dial those
    extensions. Instead, they will be connected to the menu action associated
    with that key value.

    4.

    Select Enable Operator. Enabling the operator allows callers to press zero (0) to
    reach the operator. (The default operator extension is 200.) When Enable Operator
    is On, callers cannot press 0 for other actions.

    voicemail.
    If no digit keys have been pressed five seconds after the voice prompt, the
    voice prompt replays. After replaying the voice prompt three times, the Auto
    Attendant says “Goodbye” and hangs up the call.

    Name Recording for the Auto Attendant Directory
    The administrator and individual users can create name recordings at the Desksets. When
    callers access the Directory through the Auto Attendant, the name recording plays to

    In order to create a fully functional Auto Attendant Directory, ensure that you also enter
    a name for every extension. See “Extension Basic Settings” on page 47.
    To create consistent Auto Attendant name recordings for incoming callers, ask Deskset
    users to state their name slowly, clearly, and at a reasonable volume. You may also
    recommend that users state both their name and extension number to assist incoming
    callers further.

    Creating, Editing and Deleting Paging Zones
    Use paging zones to set up extensions that can be paged as a group. For example, all
    extensions in the sales department could be defined as a paging zone. Any Deskset user
    can initiate a page to all extensions or only to the members of a paging zone. You can
    configure up to six paging zones, each with one or more members. You can place every
    extension in a paging zone.

    To create a paging zone:

    You can enter a new extension number in the range 100–999 into the Change
    Extension Number to box. The first digit of the extension number need not match
    the default extension number first digit.
    Ensure that the extension is not in use and do not assign an extension number
    with the first digit of any extension that is the same as an Auto Attendant
    menu digit key value, as callers will be unable to dial that extension. Instead,
    they will be connected to that Auto Attendant menu action. See “Configuring

    Deleting an Extension (Deskset)
    If you unplug a Deskset from the system, such as when an employee leaves, it remains
    in the system database until you use the Device Management page to delete the
    device.
    If the Auto Attendant menu programming has set a far-end key press to ring that
    extension or leave a message in its personal voice mailbox, that key assignment reverts
    to None.
    If the operator extension is deleted, the lowest extension number is automatically
    assigned as operator.
    When you delete a Deskset, only the extension number is removed from the system
    database—all local settings and personal information (Call Logs, Voicemail, etc.) remain
    stored in the Deskset. To erase all data on the Deskset (if, for example, the Deskset is
    being given to another user), press the RESET button on the Deskset for more than 5
    seconds to return all settings to factory defaults.

    Deleting a Gateway
    When replacing a Gateway, delete the old Gateway first if you want the new Gateway to
    use the same line numbers (Lines 1 to 4, for example). If you do not delete the old
    Gateway after disconnecting it, then the new Gateway will be assigned the next available
    line numbers (Lines 5 to 8, for example). System settings other than specific line numbers
    are stored in all devices, so deleting devices does not erase these settings.

    Change an Extension Number
    You can change extension numbers. Ensure that the extension is not in use when you
    make the change.

    To change a Deskset extension number:
    1.

    Back Up and Restore Settings
    Back up individual Deskset settings and system settings so that they can be restored if
    the network or a Deskset loses its settings. You can also back up a Deskset to copy the
    settings to other Desksets.
    Backup files are automatically saved on your computer using the following
    naming convention:
    backup_[device]_[extension number]_[year]-[month]-[day]_[time].cfg.
    The device will be either “ds” for a Deskset or “system” for a system backup:
    The backup file for extension 208 that was created at 4:29 PM on October 26,
    2010 would be named backup_ds_208_2010-10-26_1629.cfg.
    The system backup file that was created at 4:35 PM on October 26, 2010 would
    be named backup_system_2010-10-26_1635.cfg.
    If you are using Safari®, the backup file will be saved as a .tar file instead of a
    .cfg file. You will still be able to restore this file safely.

    Back Up and Restore Extension Settings
    Each extension has its own settings and must be backed up and restored individually.
    The following items are backed up:

    Messages and Lists: Voicemail Messages, Personal Directory, and Quick Dial



    Deskset Settings: Display, Sounds, and Preferred Audio mode

    Admin Settings: CFNA, FWD/Trans Line, Programmable Feature Keys, and User
    Password.
    Only back up one Deskset at a time. Only restore one Deskset at a time.
    If you back up an extension less than one minute after creating another
    backup for that extension, you may overwrite the earlier one, since the file
    names may be identical.

    Updating Devices
    New software versions improve system functionality. All Gateways and all Desksets
    should be running the same software version number.
    You can update all devices with one command, or you can update the Syn248 devices
    individually.
    We recommend automatic device software upgrades for installations with Internet
    access. This allows your system to obtain the latest upgrade from our server. Automatic
    upgrades may not work if your network’s firewall prohibits connection to the AT&T
    servers, or if you do not have DNS services provided by your ISP. If you need to manually
    initiate updates, see “To update all devices to the latest software version:” on page 63.
    If Internet access is not available, see “To update a single device to the latest software
    version:” on page 64.
    Sometimes devices with different versions of software cannot detect each other
    in the WebUI. Some versions of Syn248 software codes are incompatible, so that
    when you use one device's IP address for logging into the WebUI, only the
    devices with compatible code versions appear in the device lists. For this reason,
    if you are updating devices individually, wait until all other devices are updated
    before updating the software version of the device whose IP address was used
    for logging into the WebUI. When an updated device restarts with new software,
    it may disappear from the device list.
    When you add a new “out of box” device to the system, the device automatically
    gets new software from the network and then restarts. Allow this process to
    complete before using the device. The process may take anywhere between 30
    seconds to a few minutes, depending on server speed.
    Although unlikely, some types of software upgrades could interfere with
    system settings and directories. Therefore, back up the system settings and
    Deskset settings before updating the system software. If you receive automatic
    updates, back up each device after each configuration change. See “Back Up
    and Restore Settings” on page 58.
    The device restarts after a software upgrade. Ensure that there are no calls in
    progress or they will be dropped.
    If a PC is installed in series with the Deskset, restarting the Deskset causes the
    PC to lose its network connection briefly.

    requirement may cause some or all devices not to update correctly. See
    “System Upgrade” on page 99.
    The total time to update all the devices varies. The update time depends on

    Upgrade Gateway Software
    If you have system settings that you want to retain, back up the settings before upgrading
    the system software.

    To upgrade the Gateway software to the latest version:
    1.

    Press UP or DOWN in the Gateway Main menu until Configuration is highlighted
    and press SELECT to display the Configuration menu.

    2.

    Press DOWN to highlight Upgrade Software and press SELECT to initiate the

    Resetting Devices
    You may need to manually restart a device or return a device to factory defaults (see
    “Appendix D: Default Settings” on page 106). To reset a device, press the RESET button
    shown in Figure 21 and Figure 22 on page 77 by inserting a pen or paper clip into the
    hole and applying pressure to the button.
    If the device does not respond or fails to synchronize with the system, the device should
    be restarted. To restart the device without losing any custom settings, press the RESET
    button for less than five seconds. You can get the same result by disconnecting and
    reconnecting power to the device.
    To completely reset the device to factory defaults, unplug the LAN cable from the device
    and press the RESET button for more than five seconds. You might do this if the device
    is not synchronized or you want to reset the IP address settings to Auto (DHCP). Any
    static IP configurations are lost.
    When resetting a Deskset to factory defaults, the User Settings, Personal directory,
    Voicemail messages, Call Log, and the Redial list are all deleted. You can use this
    complete reset when assigning Desksets to new users. If you do not disconnect the LAN
    cable before pressing the RESET button, the extension number is retained. During the
    reset, a PC connected to the Deskset PC port momentarily loses network connectivity.
    To reset the entire system to factory defaults and completely clear the system
    of all settings (Auto Attendant, hold message, and System Directory) and
    Voicemail messages, unplug the LAN cables from all devices and press the
    RESET button for more than five seconds on each device. Then reconnect all
    devices to the LAN.
    If there is one Gateway in the system, but there are still Desksets connected, then only
    the voice prompts and hold messages are deleted; the rest of the Auto Attendant settings
    are maintained on the Desksets. If there is another Gateway, the other Gateway
    maintains all system configuration settings.
    If you have already set up the system, back up the Deskset and system settings
    before resetting the device to factory defaults. See “Back Up and Restore
    Settings” on page 58.

    Setting Intercom Call Forward–No Answer
    Intercom Call Forward–No Answer is an administrator setting to handle unanswered
    Intercom calls for each Deskset, including outside calls that have been routed to a
    Deskset by a Phone Line Call Forward–No Answer setting. See “Configuring Phone Line
    CFNA” on page 41.
    By default, Intercom calls are forwarded to Voicemail after they ring for 15 seconds. You
    can change the target destination to another extension or to an outside phone number,
    or you can turn off call forwarding when there is no answer. You can adjust the delay
    from 5 to 45 seconds.
    Calls forwarded to outside lines use two telephone lines. You can limit the
    duration of calls forwarded to outside lines with the Timer for Forwarded and
    Transferred Outside Calls setting. See “Changing the System Basic Settings”
    on page 30.
    You can also disable Fwd / Trans to Outside Line individually for each
    extension. See “Fwd/Trans to Outside Line” on page 80. If Fwd / Trans to
    Outside Line is disabled, you cannot change the target destination to an
    outside phone number.

    Common Troubleshooting Procedures
    Follow these procedures to resolve common issues.

    Resetting Devices
    You may need to manually restart a device or return a device to factory defaults (see
    “Appendix D: Default Settings” on page 106). To reset a device, press the RESET button
    shown in Figure 24 on page 85 and Figure 25 on page 86 by inserting a pen or paper
    clip into the hole and applying pressure to the button.
    To restart the device without losing any custom settings, press the RESET button for less
    than five seconds. You can get the same result by disconnecting and reconnecting power
    to the device. You can restart the device if the device does not respond or fails to
    synchronize with the system.
    To completely reset the device to factory defaults, unplug the LAN cable and press the
    RESET button for more than five seconds. You might do this if the device is not
    synchronized or you want to reset the IP address settings to Auto (DHCP). Any static IP
    configurations are lost.
    When resetting a Deskset to factory defaults, the system configuration (the user settings
    and Personal directory) and Voicemail messages, Call Log, and the Redial list are all
    deleted. You can use this complete reset when assigning Desksets to new users. If you
    do not disconnect the LAN cable before pressing the RESET button, the extension
    number is retained. During the reset, any PC connected to the Deskset PC port
    momentarily loses network connectivity.
    To reset the entire system to factory defaults and completely clear the system
    of all settings (Auto Attendant, hold message, and System Directory) and
    Voicemail messages, unplug the LAN cables from all devices and press the
    RESET button for more than five seconds on each device. Then reconnect all
    devices to the LAN.
    If there is one Gateway in the system, but there are still Desksets connected, then only
    the voice prompts and hold messages are deleted; the rest of the Auto Attendant settings
    are maintained on the Desksets. If there is another Gateway, the other Gateway
    maintains all system configuration settings.
    If you have already set up the system, back up the Deskset and system settings
    before resetting the device to factory defaults.

    Resolving General Functional Issues
    To resolve a blank screen or device that does not work at all:


    Ensure the AC plug is plugged into an electrical outlet not controlled by a wall
    switch.



    Verify that the AC power outlet has power. Try plugging in some other AC device.
    If nothing works, contact an electrician or use another power outlet.



    Verify that the DC plug is plugged into the power jack on the device.



    The system devices are not immediately active when powered up and after a
    power interruption. Allow at least 30 seconds for the device to boot up.



    If this is a Gateway, check the LED status. The POWER LED should be GREEN.



    For Desksets connected to PoE, check whether any PoE switch ports have been
    configured for devices that require less power. If so, configure your PoE switch
    to auto-detect device power requirements. For Deskset PoE specificiations, see
    “Appendix C: Technical Specifications” on page 105.

    To resolve a sluggish, unresponsive, or unusually behaving device:
    Reset the device by pressing the RESET button for less than five seconds (see Figure 25
    on page 86) or by removing and restoring AC power.
    Pressing the RESET button for more than five seconds will erase all data and
    settings.

    To resolve an incorrect system clock:
    If the system clock displays the wrong time, the system lacks Internet access for
    acquiring current time data.
    1.

    Log on to the WebUI as administrator and click System Basic Settings.

    2.

    In the System Time/Date Options section, specify a local Network Time Protocol
    (NTP) Server, or manually set the time. Then click
    .

    Resolving Audio Echoes
    The SB35010 Gateway uses automatic telephone line calibration to ensure optimal audio
    performance on outside calls. If excessive echo occurs on outside calls consistently,
    observe the Gateway line calibration data to understand any telephone line issues.
    Occasional echoes may be caused by the other person’s phone.

    To resolve audio echo issues:
    1.

    Log on to the WebUI as administrator. Click Device Management, then Device Log
    in the navigation menu at left.

    2.

    Select the Gateway from the drop-down list. Line Calibration Data appears as shown
    in Figure 26.

    3.

    Check the loss numbers within the Line Calibration Data box for each telephone line
    on each Gateway. (A loss number above 10 indicates good audio performance.)

    Figure 26. Line Calibration Data
    4.

    5.

    Troubleshooting

    If the loss number is below 10, the system will most often function normally, but
    there is an increased likelihood of audio performance issues like echo. If the loss
    number is below 10 the following procedures can be used to increase the loss value:
    a.

    Unplug that telephone line at the Gateway.

    b.

    After the line LED turns red and waiting 15 to 30 seconds, plug the line back in
    to recalibrate.

    If the recalibration has no effect, a parallel device such as a fax adapter, alarm
    system, DSL modem, or DSL splitter/filter may be connected to the system. Parallel
    external devices may affect line calibration. Disconnect these devices from the
    telephone wall jacks that are connected to the same telephone lines, as follows:
    a.

    Unplug these non-system external devices from their telephone wall jacks.

    b.

    Unplug the telephone line connections from the Gateway.

    c.

    After the Gateway Line-Status LEDs turn red and waiting 15 to 30 seconds, plug
    the telephone lines into the Gateway again to recalibrate.

    d.

    If there is a significant increase in the loss number and improved audio
    performance on those lines after disconnecting a parallel device, consult your
    telephone service provider to either investigate the problem or to install separate
    lines for those parallel devices.

    Resolving General Audio Issues
    Check the following if you hear static, sudden silences, gaps in speech, echoes, distorted
    speech, or garbled speech.

    To resolve general audio issues:
    You may be experiencing network problems.




    Your LAN administrator should ensure the following minimum guidelines are met:


    A switched network topology, which requires attaching network components
    to switches rather than hubs, is recommended. The network should use
    standard 10/100 Ethernet switches that carry traffic at a nominal rate of
    100 Mbit/s.



    The office network infrastructure should use Cat.-5 wiring.

    Do not connect a network server PC to the PC port on the Deskset.

    If you have Digital Subscriber Line (DSL) service, you may be experiencing telephone line
    problems.


    Make sure you have a DSL filter plugged in between each DSL line and the
    telephone wall jack.



    You may need a higher quality DSL filter than you are currently using. You can
    also try plugging in multiple DSL filters in sequence to decrease DSL interference.



    Move the DSL line to the lowest priority line, which is Line 4 on the highest
    numbered Gateway, as indicated on the Gateway display.

    The Gateway might not have recognized a new outside telephone line, so line calibration
    — which allows the Gateway to adjust its performance depending on the phone lines’
    characteristics — did not occur. After unplugging the telephone line, wait for 15 to 30
    seconds before plugging the telephone line back into the Gateway.

    Reintroducing a Deskset Into the System
    If there are no more than 24 Desksets in the system and a Deskset screen displays Synch
    Failed or Synchronizing for a long time, you may need to remove the Deskset from the
    system and reintroduce it. This problem may have been caused by a network disruption,
    the Deskset having been part of a different network, or by an AC power failure.

    To reintroduce a Deskset into the system:
    1.

    Ensure that the Deskset is connected to the same LAN subnet as other system
    Gateways and Desksets. Ensure that the PC you will use to access the WebUI is either
    on the same subnet as Syn248, or that the PC subnet can communicate with the
    Syn248 subnet. Devices on the same subnet generally share the first three octets of
    their IP addresses. If the subnets are different, contact your installer.

    2.

    If you want to retain the programming for a problem Deskset, back up the Deskset.
    a.

    Troubleshooting

    Log on to the WebUI as administrator on the problem Deskset. Click Device
    Management, then Back up/Restore, and then Extension Settings in the
    navigation menu at left.

    Select the extension from the Select Extension to Back up drop-down list, and
    click
    to save the file to a specified location on your computer.
    You will need to locate and retrieve this file later, so make sure you remember
    where you saved it. The default file name will be in the format:
    backup_ds_[extension number]_[year]-[month]-[day]_[time].cfg.
    If you back up the same extension less than one minute after creating the
    backup, you may overwrite the earlier backup file.

    3.

    Perform a complete factory reset to return to the values set at the factory.
    a.

    Unplug the LAN cable.

    b.

    Insert a pen or the end of a paper clip into the RESET button, located on the
    underside of the Deskset. Hold until Restoring to Factory Defaults appears on
    the screen (approximately 5 seconds).

    After the Deskset restarts, the screen displays EXT 0.
    c.

    Reconnect the LAN cable.
    The Deskset rejoins the system. Unless the entire system was reset, the Deskset
    retains its previous extension number. After the Deskset rejoins the system, the
    screen changes from EXT 0 to the previous extension number.

    4.

    If you backed up the Deskset settings in Step 2, restore your settings.
    a.

    Log on to the WebUI as the Administrator at the PC where you stored the backup
    file.
    Syn248 Desksets with static IP addresses need to have new addresses assigned
    if the Deskset IP addresses are to be used for logging into the WebUI. At the
    Deskset, press MENU –> 3 –> 3 –> 2 to set the IP address.

    Troubleshooting

    b.

    Click Device Management, then click Back up/Restore.

    c.

    Under Restore Extension Settings, select the Deskset's extension number
    from the Select Extension to Restore drop-down list. See “Back Up and
    Restore Settings” on page 58.

    d.

    Select the backup file.

    e.

    Click Restore Extension.

    Power Failure Recovery Procedure
    The Syn248 system automatically recovers after a power failure. The following describes
    the recovery process.
    Allow about a minute for the Gateway to boot up when power returns after a power
    failure. The power-up sequence for the Gateway follows:
    1.

    About 20 seconds after turning on power to the device, the POWER LED turns on.

    2.

    When the device finds the network, Synchronizing momentarily appears, indicating
    that the device is in the process of detecting and synchronizing with other system
    devices.

    30 )(%
    3671 /LQHV   
    6\QFKURQL]LQJ
    3.

    Once the device has successfully finished synchronizing with the rest of the system,
    Synchronized appears.

    30 )(%
    3671 /LQHV   
    6\QFKURQL]HG
    ,3 
    When AC power returns after a power failure, the system self-assigns a link-local address
    to the Deskset beginning with number 169.254.


    If the Deskset is set for automatic IP address configuration, it searches for the
    DHCP server. If the DHCP server is found, it assigns an IP address.



    If the Deskset is set with static IP addresses, the address does not change.

    We recommend that you check each Deskset and Gateway to confirm that it has started
    up properly.
    If any of the system devices’ screens report Synch Failed or Synchronizing for more
    than 10 minutes, see “Reintroducing a Deskset Into the System” on page 88 for recovery
    methods from these states.
    i

    The time and date may not be correct. The time and date are set using the
    WebUI “System Settings” on page 30.
    The Desksets also automatically restart and synchronize after an AC power
    failure.

    Some systems will take longer than others depending on the network topology.

    If the update has failed (you see a failure
    message), retry
    . Allow sufficient
    time for the upgrade process to complete. You
    may prefer to schedule a system update to take
    place overnight.



    Update individual devices manually either
    through the front panel or through the WebUI for
    that particular device.
    If you are using the WebUI to upgrade the
    device, ensure that you log on using that
    device’s IP address.



    Power cycle each device that did not get
    upgraded. Unplug the power cord and plug it
    back in. As each device reboots, it automatically
    updates if it detects updated software in the
    system.

    An extension number was not changed correctly.

    Troubleshooting

    Probable Cause

    Corrective Action

    That extension may have
    been on a call while the
    extension number was
    changed in the WebUI, or
    someone tried to change the
    extension number to a
    number that was already
    being used.

    System Upgrade
    A Syn248 device becomes sluggish or unresponsive during or immediately after software upgrade.
    Probable Cause

    Corrective Action

    Cannot connect to AT&T
    server or the device
    encountered an unexpected
    problem.



    Disconnect the power to the device, wait a few
    minutes, then reconnect the power and try the
    upgrade process again.

    During device upgrade one of the following messages appears: “UNKNOWN ERROR Current image
    version” or “UNKNOWN ERROR”.

    Troubleshooting

    Probable Cause

    Corrective Action

    A communication error
    between the devices and the
    server.



    If this failure occurred after clicking
    , power cycle each device that
    did not get upgraded. Unplug the power cord and
    plug it back in. As each device reboots, it
    automatically updates (if it detects updated
    software in the system).



    Wait 30 minutes to allow for the device to
    update. If the system has a very low bandwidth
    Internet connection, it may take up to 4 hours.



    If this failure occurred during a manual
    single-device update, power cycle the device that
    did not get upgraded. Unplug the power cord and
    plug it back in. As the device reboots, it
    automatically updates if it detects updated
    software in the system.

    User WebUI
    Unable to access the WebUI Log-in page from my computer.
    Probable Cause

    Corrective Action

    The computer is not
    connected to the same
    subnet (network) as the
    Deskset, and the subnets are
    not set up to communicate.



    Verify the IP address. You must correctly enter
    the IP address of your Deskset into your Internet
    browser’s address bar. At the Deskset, press
    MENU –> 4 to see the IP address displayed in
    the third line of the information.



    Ensure that there is an LAN cable attached to
    Network port on the Deskset and to the LAN. If a
    PC at the same workstation is sharing the LAN
    connection, attach a network cable to your
    computer’s network port and to the PC port on
    the back of the Deskset.



    Confirm that your computer and your Deskset are
    on the same subnet so that they can talk to each
    other. Check that the first three sections of each
    IP address are the same. If they are not, they may
    not be connected to the same subnet. Contact
    the installer; the subnets may not be set up to
    communicate.



    Use the network IP address assigned through
    DHCP or manually in the address bar of the
    browser.

    The local address, rather
    than the network IP address,
    was used in the address line

    PC/Deskset Interaction
    Internet connection or access to the local network on my computer does not work after installing
    the Deskset.
    Probable Cause

    Corrective Action

    The LAN cables are not
    installed correctly.



    Check that the network cable from the computer
    is plugged into the Deskset port labeled
    .A
    second LAN cable should be plugged into the
    port on the Deskset marked
    with the other
    end plugged into your LAN.

    My PC is slower now that I have connected it to the LAN through the Deskset.
    Probable Cause

    Corrective Action

    A computer connected
    through the Deskset will be
    limited to 100 Mbits/s.



    Use separate network connections for the
    Deskset and the computer so that the computer
    can take advantage of the network’s greater
    bandwidth.

    My PC, which is connected to the LAN through the Deskset, briefly loses its network connection.

    Troubleshooting

    Probable Cause

    Corrective Action

    For PCs connected to the
    LAN through Desksets,
    disruption to the Deskset
    operation affects the PC. For
    example, when the Deskset
    restarts (possibly due to a
    software upgrade) the
    connection to the LAN is
    temporarily lost.



    If the PC is connected to the LAN through the
    Deskset, avoid updating software or restoring the
    Deskset settings when a user is at the
    workstation.



    If the PC is connected to the Deskset, and if the
    PC is connected to an Uninterruptible Power
    Supply (UPS), plug the Deskset into a UPS.



    Use separate network connections for the
    Deskset and the computer.

    troubleshooting section, see the SB35020 Deskset User’s Guide at
    www.telephones.att.com/smb.
    Other Desksets do not appear in the extension list.
    Probable Cause

    Corrective Action

    The Deskset is not connected
    to the same subnet as the
    other Desksets.



    Verify that the first two sections of the IP address
    (the portion before the second “dot”) match the
    IP addresses of the other Desksets or that the
    subnets are set up to communicate with each
    other. Press MENU –> 4 at a Deskset to find the
    IP address.



    If the other Desksets have been assigned static IP
    addresses, you may have to assign your Deskset
    a static IP address to match the other Desksets.

    Users cannot add Quick-Dial entries.

    Troubleshooting

    Probable Cause

    Corrective Action

    You must configure one or
    more Programmable Function
    Keys as Quick Dial keys
    before they can be used.



    Configure one or more Quick-Dial keys for the
    Deskset. See Feature Keys under the Extension
    Settings menu.

    Appendix B: IP Addresses and Connectivity
    An IP address is an individual numeric identification assigned to devices on a computer
    network. At least one Syn248 device needs a network-assigned IP address on the subnet
    shared with any computers that will allow access to the WebUI. Valid IP addresses on the
    same subnet allow devices on the network to identify each other and enable
    communication.
    This IP address may be assigned from a Dynamic Host Configuration Protocol (DHCP)
    server, or set statically to the same subnet, and will be separate from the self-assigned
    169.254.xxx.xxx link-local address that the Syn248 devices use to communicate with
    each other. When setting up the IP address on a Syn248 device, this network IP address
    used for WebUI connectivity is the only address you can change.
    The network IP addresses can be assigned in two ways:
    1.

    The Syn248 device can request a network server to automatically assign an IP
    address. This IP address is a dynamic assignment; the address is on lease from the
    server. The lease is renewed as long as the device remains connected and there is
    no change to the network. However, if the device is disconnected, or if there is a
    network or AC power interruption, the lease may not be renewed (that is, the IP
    address expires) and a new IP address may be assigned.
    Most LANs use servers to automatically assign IP addresses. Syn248 defaults to
    assuming that this automatic assignment will occur.
    Some servers have default settings that limit the number of network IP
    addresses assigned to devices on the network. You should log in to your server
    to confirm that the IP range is sufficient to accommodate at least one of the
    Syn248 devices that you are adding as at least one Syn248 device needs an
    assigned IP address to enable WebUI configuration activities. Consult the IT
    department if you need help checking the server.

    2.

    Appendixes

    The Syn248 system administrator can manually assign a static system IP address. This
    IP address does not change, even when there are network or AC power interruptions.
    Some installations will require manual static IP assignment. You can assign a static
    IP address for a Gateway using the device front panel interface. See “Gateway
    Configuration” on page 74. You can assign a static IP address for a Deskset from the
    Deskset IP Settings menu. See “IP Settings” on page 80.
