System Overview
AT&T SB35010 Analog Gateway — Each Gateway
provides access to up to four analog outside
telephone lines. A system can have up to two
Gateways, supporting up to eight telephone lines.
AT&T SB35020/SB35025 Deskset — These Deskset
models feature a standard screen and programmable feature keys. A
system can have up to 24 Desksets. The SB35025 has a DECT 6.0
radio to host an optional cordless headset and an audio in/out port
for connecting a Music on Hold (MoH) source and an overhead paging
system.
AT&T SB35031 Deskset — This Deskset model features a large
screen and a DECT 6.0 radio to host an optional cordless headset. A
system can have up to 24 Desksets, and you can combine SB35031
and SB35020/025 Desksets.
AT&T DECT Cordless Accessory Headset (Optional, requires
SB35025 or SB35031 Deskset) — The headset lets you work while you
talk.
Web User Interface (WebUI) — The WebUI
enables you to customize your system using a PC
that is connected to the same Local Area
Network. The WebUI resides on the Gateways and
Desksets, and is updated with device software
updates. See “System Configuration” on page 35
and “Updating Devices” on page 74.
The Syn248 system can be expanded to support two Gateways and up to eight
lines. For more information, see “Appendix A: Expanding Your System” on
page 118.
You can register only one AT&T DECT Cordless Headset to a Deskset. Up to five
Desksets can have cordless accessories, although this number can increase
depending on your office environment. Factors such as proximity of Desksets,
number of simultaneous calls, and structural obstacles affect how many
Desksets can have cordless accessories. When a Deskset has cordless
accessories, they are all part of the same extension, and only one extension
device can be used at a time.
To register a cordless headset to a Deskset, see “Cordless Headset
Installation and Registration” on page 30 rather than the manual that is
packaged with the headset.

System Installation Overview
Figure 1 illustrates how the Syn248 system differs from conventional telephone systems
in that calls are not coordinated by a central controller. Instead, the system uses a
distributed control system over a new or existing local area network (LAN).

Syn248 Installation and Configuration Guide Back to Contents
Installation 11
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. If you do not have a DHCP
server or do not manually assign static IPs, you will not be able to access the
Syn248 WebUI and/or enable automatic time updates from an NTP server.
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 119.
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.
Syn248 Installation and Configuration Guide Back to Contents
Installation 12
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.
Syn248 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 120.
Other Preparations
Before installing the Gateway and Desksets, the following preparations may need to be
taken:
All telephone lines must be gathered into one access point situated no more
than 9 feet (2.74 m) from the Gateway location. If you need to rewire your lines,
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.
Syn248 Installation and Configuration Guide Back to Contents
Installation 13
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 is restored 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 59).
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.
Figure 2. Two-line Adapter
To Wall Jack
To Gateway
Syn248 Installation and Configuration Guide Back to Contents
Installation 14
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. See
“Deleting Devices” on page 68. 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.

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:
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

To connect the Deskset to the network:
1. Plug a Cat.-5 Ethernet cable into the Network port on the back of the Deskset.
2. Plug the other end into an Ethernet wall jack that connects to your LAN switch.
If there is a networked computer and no extra Ethernet wall jacks near the Deskset, then
the Deskset and PC can share the same network connection.
1. Unplug the Cat.-5 Ethernet cable from your computer.
2. Plug that Cat.-5 Ethernet cable into the Network port on the back of the Deskset, as
shown below.
3. Plug another Cat.-5 Ethernet cable into the PC port on the Deskset.
4. Plug the other end of the second Cat.-5 Ethernet cable into your computer.
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.
PC
Network
The PC port on the Deskset is intended for connection to an end-user PC only.
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.

To connect power:
If you are using PoE, connecting the Deskset to the network also connects the power.
If you are using the supplied power adapter:
1. Plug the power adapter (blue tag) into the DC Power jack on the back of the Deskset.
2. Plug the power adapter into an outlet not controlled by a wall switch. The display
screen illuminates within a minute.
If the user's computer is plugged into an uninterruptible power supply (UPS), consider
plugging the Deskset into it, too. This will help prevent a computer connected to the
Deskset PC port from losing its network connection during a power outage (providing
that other network resources have backup power as well).

Connecting an Overhead Paging System (OHP)
You can connect a single-zone overhead paging system to an SB35025 Deskset using
the supplied audio in/out cable. Syn248 supports one single-zone paging system per
Syn248 system. If necessary, you can connect both an overhead paging system and a
Music on Hold source to a single SB35025 Deskset using the supplied audio in/out cable.
Syn248 supports most OHP systems that support auxiliary audio-out connections to a
PBX. You should also refer to your OHP system's product documentation for installation
and configuration instructions or contact your OHP equipment provider. Some settings
for the OHP may have to be changed to work with Syn248.

a custom cable for the final connection to the paging system. One end of this
cable must have a 1/8-inch (3.5 mm) jack to connect to the supplied audio in/out
cable.
When connecting an overhead paging system, ensure that you use the supplied
audio in/out cable to connect the system to the SB35025 Deskset AUX I/O port.
The supplied audio in/out cable terminates in a ring/sleeve (or ground)
connection at the “Paging Output” jack. Ensure that the cable that connects
between the supplied audio cable and your overhead paging system is
compatible with this configuration. The cable connector shown below would be
compatible.
Ring Sleeve
Whether you are replacing a phone system and using an existing, functional
OHP, or installing a new OHP, the paging system may have settings that need
to be adjusted to work with Syn248.

To install an overhead paging system:
1. Plug an audio cable from the OHP device into the “Paging Output” jack of the audio
in/out cable supplied with the SB35025 Deskset, as shown in Figure 13.
Figure 13. Overhead Paging System Connection
If you need to hard-wire a connection between your OHP device and the supplied
audio in/out cable, you can configure a stereo audio cable as follows:
a. Remove the 1/8-inch (3.5 mm) plug from one end of the cable.
b. Strip enough shielding from the cable to expose the three wires inside.
c. Identify the Ring (Right channel) and Ground wires. Depending on the cable, the
Ring wire may be red and the Ground wire may be bare/unshielded, as shown in
Figure 14. You can use a voltmeter to properly identify the wires.
Figure 14. Hard-Wiring a Stereo Cable to the OHP
d. Trim the Tip (Left channel) wire to ensure it does not contact other wires or
terminals.
e. Connect the Ground wire to the negative terminal and the Ring wire to the
positive terminal on the OHP device.
f. Connect the other end of the hardwired cable to the “Paging Output” jack of the
supplied audio in/out cable.
2. Connect the supplied audio in/out cable to the SB35025 Deskset AUX I/O port.

Connecting a Music on Hold Source
Your music on hold (MoH) source can be a streaming audio source, such as a radio or
MP3 music player. The audio source must have a volume control. The volume adjustment
on the audio device should be set to obtain the preferred level of music on hold within
the system.
On-hold music functionality should only be used in conjunction with music
specifically licensed for on-hold use. Licensed on-hold music is available from
many third-party suppliers. AT&T disclaims any liability arising from the failure to
obtain such a license.
When connecting an MoH source, ensure that you use the supplied audio in/out
cable to connect the source to the SB35025 Deskset AUX I/O port.
The supplied audio in/out cable terminates in a tip/sleeve (or ground)
connection at the “Music on Hold Input” jack. Ensure that the cable that
connects between the supplied audio cable and your MoH source is compatible
with this configuration. Either cable connector shown below would be

Phone Line CFNA” on page 53. 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.
There are three Auto Attendant menus available — the Default menu, a Day Menu, and a
Night Menu. The Default menu instructs callers to “Enter the extension number or enter
0 for the operator.” You can select the current active Auto Attendant menu using the
Deskset that is set as the Operator extension (see “Setting the Current Auto-Attendant”
on page 46).
You can configure the Day Menu and Night Menu with your own voice greetings and
key-press commands. You cannot customize the Default menu.
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”

5. Set the dial key values. Program an action for each digit as needed by selecting the
action from each digit’s drop-down list.
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.

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 76.
If Internet access is not available, see “To update a single device to the latest software
version:” on page 77.
Adding a New Deskset to an Existing System
When you add a new Deskset to an existing Syn248 system, it may require a software
upgrade in order to enable the latest Syn248 system features. In this case, the Deskset
will prompt you to upgrade its software.
The first release of Syn248 included SB35020 Desksets running software version 1.0.0. If
you add Deskset models SB35025 or SB35031 to your system, you should upgrade the
software to take advantage of the new Deskset features. Syn248 software version 1.3.1
and higher for the SB35031 and SB35025 Desksets includes enhanced SB35025 Deskset
features such as Music on Hold and Overhead Paging.
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 on to 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 on to the WebUI. When an updated device restarts with new
software, it may disappear from the device list.
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 70.
The device restarts after a software upgrade. Ensure that there are no calls in
progress or they will be dropped.
If a PC is connected to the Deskset PC port, restarting the Deskset causes the
PC to lose its network connection briefly.

How to Upgrade Software After Adding a New Device
Upgrading Syn248 software is simple. You need a reliable Internet connection for your
network.
After you connect your new Deskset, the screen prompts you to upgrade the software. If
you have more than one Deskset to install, connect them all and wait for the upgrade
prompt to appear on all Desksets.
If you press :
All Syn248 devices in the system will be upgraded. If you have multiple Desksets
to install, you only have to press on one of the Desksets.
After the upgrade, all Syn248 devices will reboot. Wait approximately five
minutes for the reboot process to complete.
Once the entire system is upgraded, any Deskset with old software that you
connect in the future will be upgraded automatically.
If you want to defer the upgrade and press :
The device will work with the current software version on all devices, but with no
enhanced features.
The phone will no longer ask you to upgrade.
You can perform a site-wide software upgrade later. See “To update all devices

Using requires a minimum Internet download bandwidth of
1 Mbps and an Internet router that can handle the same number of total
simultaneous connections as the number of Syn248 devices. Refer to your
router specification. Performing an update without meeting the minimum
requirement may cause some or all devices not to update correctly. See
“System Upgrade” on page 112.
The total time to update all the devices varies. The update time depends on
Internet connection speed, the number of connections to the server, and the
number of devices in the system. AT&T recommends conducting system
updates overnight to reduce the impact on Deskset users.
You can only update one device at a time. Only the selected device is
updated.
If the device is sluggish or unresponsive during the upgrade process, see “A
Syn248 device becomes sluggish or unresponsive during or immediately
after software upgrade.” on page 112.
When an updated device restarts with the new software, it may disappear
from the device list if its software version is incompatible with the device
whose IP address was used for logging on to the WebUI.

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 121). To reset a device, press the RESET button
shown in Figure 26 and Figure 27 on page 98 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 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, voice
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.
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.
Figure 26. Gateway Reset Button
To reset the entire system to factory defaults and completely clear the system
of all settings (Auto Attendant, hold message, and System Directory) and voice
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 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 70.

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 Power over Ethernet (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 specifications, see “Appendix C: Technical Specifications” on
page 120.
To resolve a sluggish, unresponsive, or unusually behaving device:
Reset the device by pressing the RESET button for less than five seconds (see Figure 27
on page 98) or by removing and restoring AC power.
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.
3. Click .

Troubleshooting 99
Resolving Audio Echoes
If excessive echo occurs on outside calls consistently, there are two approaches you can
take to troubleshoot the condition:
1. Check line calibration and parallel devices. The SB35010 Gateway uses automatic
telephone line calibration to ensure optimal audio performance on outside calls. You
can observe the Gateway line calibration data to understand any telephone line
issues and recalibrate the lines, if necessary. Echoes may sometimes be caused by
other devices using your PSTN lines, or by an outside caller’s phone.
2. Adjust Echo Suppression and Line Loop Length settings.
To check line calibration and parallel devices:
1. Log on to the WebUI as administrator. In the navigation menu at left, click Device
Management, then click Advanced PSTN Settings.
2. Select the PSTN Gateway from the Select Gateway list. Line Calibration Data
appears.
3. Check the loss numbers within the Line Calibration Data table for each telephone
line connected to the Gateway. A loss number above 10 indicates good audio
performance.
4. 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. Click the Calibrate button for the affected line.
b. Wait one minute, then click Refresh Line Calibration Data.
5. 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. Recalibrate the affected line.
c. If there is a significant increase in the loss number and improved audio
performance on those lines after disconnecting a parallel device, you may want
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. Try unplugging the telephone line, then
waiting for 15 to 30 seconds before plugging the telephone line back into the Gateway.
Reconnecting a Deskset to 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 reconnect 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 reconnect a Deskset to 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. 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.
Syn248 Installation and Configuration Guide Back to Contents
Troubleshooting 102
b. 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.
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 on to the WebUI. At a
Deskset, press (MENU) –> 3 –> 3 –> 2 to set the IP address.
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 70.
d. Select the backup file.
e. Click Restore Extension.
If you back up the same extension less than one minute after creating the
backup, you may overwrite the earlier backup file.

Troubleshooting 103
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.
3. Once the device has successfully finished synchronizing with the rest of the system,
Synchronized appears.
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 “Reconnecting a Deskset to the System” on page 101 for recovery
methods from these states.

Troubleshooting 117
MoH audio is too quiet, fluctuating, or dropping out.
Probable Cause Corrective Action
The volume on the audio
source is too low or too high.
If the volume is too high,
overdriven audio
components may be causing
short periods of sound to
drop out (not be heard).
If you can adjust the output volume of your audio
source (like the headset jack of an MP3 player),
call into your Syn248 system, place the call on
hold, listen to MoH on the outside line, and adjust
the audio volume on your audio source up or
down until the best sound quality is achieved.
If you created a recording to use as the audio
source, try to adjust the recording volume by
speaking louder or speaking closer to the
microphone.
Use different hold music. Some types of music
sound better than others when played across a
telephone line. For example, classical music with
extreme volume fluctuations may not sound very
good when used as MoH.
Use of audio source outputs
whose levels are not
adjustable, such as RCA “Line

Appendixes 119
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 network IP address may be assigned from a Dynamic Host Configuration Protocol
(DHCP) server, or set statically to the same subnet. The network IP address 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. In a home or small office environment, the server is usually your router. This
IP address is assigned dynamically; 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. By default, Syn248
assumes that this automatic assignment will occur.
2. 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 86. You can assign a static IP address for a Deskset from the
Deskset IP Settings menu. See “IP Settings” on page 92.
Some servers have default settings that limit the number of network IP
addresses assigned to devices on the network. You should log on to your
server (in most cases, this will be your router) to confirm that the IP range is
sufficient to accommodate at least one of the Syn248 devices that you are
adding. At least one Syn248 device needs an assigned IP address to enable
WebUI configuration activities.
