System Installation Overview
Figure 1 illustrates how the Synapse 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 LAN.
Figure 1. Sample System Network
A system must have at least one PSTN Gateway, one T1 Gateway, or one SIP Gateway.
There can be up to four PSTN Gateways, and a system can include a T1 Gateway, SIP
Gateway, and PSTN Gateways. Figure 2 illustrates the minimum components needed to
make the system work (blue line = telephone; red lines = Ethernet).
Figure 2. Simplified System (PSTN Gateway and SB67030/031 Deskset Shown)
The system uses a Local Area Network (LAN) for system communication. It uses
Public Switched Telephone Network (PSTN) connections for outside calls.

System Installation Overview with Optional Analog Terminal Adapter
If you have analog devices that you want to attach to the system, you will need an AT&T
SB67050 Analog Terminal Adapter (ATA). The Synapse system supports one ATA per
system. The ATA allows you to attach hardware such as conference phones, overhead
paging equipment, a fax machine, or a source for Music On Hold (MoH) to Synapse.
Figure 3 illustrates a more complex installation (blue lines = telephone; red lines =
Ethernet; orange lines = audio), but there are different options for attaching some of the
equipment to the ATA.
Install the ATA after you have installed at least one Gateway and the Desksets.

System Installation Overview for Remote Sites
If two separate Synapse systems both have SIP Gateways, then they can communicate
with each other as “Remote Sites” on a privately managed network. Remote Sites allow
users to make extension-to-extension calls between Synapse sites, thus avoiding
long-distance charges. Users can also call external numbers at a Remote Site by routing
a call through a remote Gateway, thereby completing a long-distance call as a local call.
To use Remote Sites, you must set up a dedicated router-to-router Virtual Private
Network (VPN) between each site. This type of installation requires the following at each
site:
A router that supports simultaneous VPNs and IPsec. AT&T recommends using
IPsec VPN.
A static Wide Area Network (WAN) IP address at both sites
Each Synapse site should be on a different LAN subnet.
See also “SIP Gateway Static IP Configuration” on page 16.
Configuring Remote Sites requires some coordination between the system administrators
for each site. To configure Remote Sites, you must configure one Remote Site SIP
Account for every other remote site. For more information, see “Configuring Remote
Sites” in the Synapse Administrator‘s Guide at
www.telephones.att.com/synapseguides.
Figure 4. Example of Remote Site Installation
Ensure that you configure the VPN to allow communication between the
two SIP Gateways by entering each Gateway’s private IP address into the
VPN setup.

Recommended Installation Sequence
1. Prepare your site for installation. See “Site Preparation” on page 26.
2. Install the Gateway(s). See “Gateway Installation” on page 35.
3. If you have only one Gateway, install the first Deskset. See “Deskset Installation” on
page 38. This Deskset is assigned extension number 200 with no Direct Inward
Dialing.
4. If necessary, use the WebUI to change the mode of operation from Call Appearance
mode to Line Appearance mode. See “About Modes of Operation” on page 15.
5. Configure the Dial Plan Settings and [T1/SIP]Direct Inward Dialing (DID). Unless you
do this, the other Desksets will be assigned sequential three-digit extension numbers
starting with 201 and without DID numbers.
For more information about Dial Plan and DID configuration, see the Synapse
Administrator’s Guide at www.telephones.att.com/synapseguides.
Use the WebUI to change the Dial Plan Settings if you want the first extension digit
to be something other than 2, possibly to correspond to the DID numbers, or if you
want the parked-call extension numbers to start with a digit other than 1.
After changing the Number of Digits and Default Phone Extension Prefix, manually
change the extension number of the first Deskset you installed, and manually set its
DID number.
Changing the number of extension digits after installing some Desksets may result in
undesired extension number re-assignment, where the last three digits of previous
extension numbers may not be preserved.
6. Install the other Desksets. See “Deskset Installation” on page 38.
7. Optional: Install the AT&T SB67050 Analog Terminal Adapter (ATA). See “SB67050
ATA Installation” on page 45. If you install the ATA with phones or a fax machine
connected to an FXS port before installing a Deskset, that device will default to being
the operator. Install the ATA after installing at least one Deskset so that a Deskset
is the default operator.
8. Connect any analog device such as a fax machine, paging system, or door phone to
the ATA. For more information, see:
“Connecting Analog Telephones” on page 45
“Connecting a Fax Machine” on page 46
“Connecting an Overhead Paging System (OHP)” on page 47
“Station Port (FXS) Door Phone Support” on page 23.
9. Configure the system using the WebUI.
You cannot enable Line Appearance mode if a T1 Gateway or SIP Gateway is
installed in your system. Line Appearance mode is not compatible with the T1
Gateway and SIP Gateway.

See “System Configuration” on page 78 and the Synapse Administrator’s Guide
at www.telephones.att.com/synapseguides.
10. Complete post-installation tasks.
If you have set the system to use Call Appearance mode, ask all users to record
their user names on their Desksets.
See “Name Recording for the Auto Attendant Directory” in the Synapse
Administrator’s Guide at
www.telephones.att.com/synapseguides.
If you have set the system to use Call Appearance mode, distribute and register
any Cordless Handsets or Headsets. Synapse Cordless Handsets are not
compatible with Line Appearance mode. See “SB67040 Cordless Handset
Installation” on page 50 and “TL7600 Cordless Headset Installation” on page 53.
Check for software upgrades and register your Synapse system products. See
“Updating Devices” on page 91 and “Product Registration” on page 94.

Planning Your System and Network Configuration
This section describes several important configuration options that you should be aware
of before you install the Synapse system. These options include Operation Mode (Call
Appearance versus Line Appearance), IP addresses and connectivity, extension number
assignments, analog bypass lines and analog telephones in the Synapse system.
About Modes of Operation
The system administrator can configure the Synapse system to operate in one of two
different modes: Call Appearance mode and Line Appearance mode. The operation mode
affects how Deskset users make, answer, and manage calls. Each mode provides a unique
set of configurable features.
Before beginning the installation, you and the system administrator should decide which
mode will work best for the site.
Call Appearance Mode
In Call Appearance mode, each Deskset has virtual “lines” (5 on SB67030/031 Desksets,
and up to 10 on SB67020 Desksets) for calls to and from external numbers
(232-555-0176, for example) or other extensions (Extension 220, for example). These
virtual lines are called Call Appearances.
Systems using Call Appearance mode can have any combination of PSTN Gateways, T1
Gateway, SIP Gateway, and an optional ATA. In Call Appearance mode, SB67030/031
Desksets can have SB67040 Cordless Handsets and TL7600 Cordless Headsets.
Line Appearance Mode
In Line Appearance mode, each line that Deskset users can access corresponds to an
actual physical line connected to the PSTN Gateway (the Synapse system can have up to
four PSTN Gateways providing up to 16 lines). Incoming lines are mapped to
Programmable Feature Keys on Desksets. You can assign different lines to different
Desksets or groups of Desksets. You can configure SB67020 Desksets to access up to 9
lines and SB67030/031 Desksets to access up to 4 lines.
Other Desksets in the system can share these lines and display the line status. Incoming
calls on a line ring at all Desksets that share that line. Users at Desksets that share lines
can see when lines are ringing, busy, or on hold.
Systems using Line Appearance mode must use PSTN Gateways only. An optional ATA is
also compatible with Line Appearance mode. For more information, see “ATA Fax Line
Configuration” on page 29. A system using Line Appearance mode cannot support the
T1 Gateway, SIP Gateway, Ring Groups, Call Queue and some Deskset-specific features.
For more information, see the Synapse Administrator’s Guide at
www.telephones.att.com/synapseguides.
In Line Appearance mode, SB67030/031 Desksets cannot use SB67040 Cordless
Handsets, although TL7600 Cordless Headsets are compatible with Line Appearance
mode.

Synapse Installation Guide Back to Contents
Installation 16
IP Addresses and Connectivity
An IP address is an individual numeric identification assigned to devices on a computer
network. At least one Synapse 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 Synapse devices use to communicate with
each other. When setting up the IP address on a Synapse 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 Synapse 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. Synapse defaults to
assuming that this automatic assignment will occur.
2. The Synapse 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 or ATA using the device front panel interface. See “Gateway
Configuration” on page 64.
A switched-network topology is recommended. This topology refers to the network
virtual shape or structure and does not necessarily reflect the physical layout. Switched
networks involve connecting the network components to switches rather than hubs; this
improves network communication.
SIP Gateway Static IP Configuration
If your SIP service provider requires static registration for a SIP Gateway, please ensure
that:
The SIP Gateway uses the same IP address, preferrably via a static mapping in
the DHCP Server. If this is not possible, you can configure a static IP address
using the SIP Gateway’s front panel.
Port forwarding on your router is configured to route UDP 5060 traffic from the
WAN side to the SIP Gateway LAN IP address.
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
Synapse devices that you are adding as at least one Synapse device needs an
assigned IP address to enable WebUI configuration activities. Consult the IT
department if you need help checking the server.

Synapse Installation Guide Back to Contents
Installation 17
SIP ALG (application-level gateway) functionality may be required if the SIP service
provider does not use hosted NAT traversal.
Extension Assignments
The system assigns the first Deskset to join the network as extension 200. At this point
you can use the Dial Plan Settings page in the WebUI to set a different first digit for
extension numbers for Desksets that will be connected to the network. The WebUI calls
this the Default Phone Extension Prefix. If desired, you should also change the number
of digits from three to four at this point.
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 unplug a unit, its extension number is reserved. If you want to remove an
extension from the network, you must delete the extension number using the WebUI
Device Management menu. Deletion ensures that the Deskset does not tie up an
extension. You can use the WebUI to change or delete extension numbers.
If your site is one of several Remote Sites using SB67070 SIP Gateways, depending on
your dial plan and other configuration, you may want to ensure that extension numbers
do not overlap with the Remote Sites. You can prevent overlap either by choosing a
unique first digit (Default Phone Extension Prefix) or by restricting your extension
numbers to a range. For example, your site uses 200 to 249, while another site uses 250
to 299.
For more information, see the Synapse Administrator’s Guide at
www.telephones.att.com/synapseguides.

Synapse Installation Guide Back to Contents
Installation 18
Connecting Analog Devices to the ATA
The ATA allows you to attach the following analog devices to the ports and jacks
identified in Figure 23 on page 45. Most options require the system administrator to
configure the feature in the WebUI. If you are planning to install more than one type of
analog equipment, make sure there are suitable ATA ports available and configured.
Analog telephones, including conference phones
If not used for a fax machine or for Overhead Paging, the two FXS station ports
on the ATA allow for connecting standard POTS (Plain Old Telephone Service)
analog telephones and conference phones. When an ATA is added to the
Synapse system, the FXS ports are automatically assigned extension numbers
that can be changed by the system administrator using the WebUI. Users can
make and receive calls on those analog telephones, but system features such as
Hold, Call Forward, and Transfer are not supported. You can use the WebUI to
assign features such as Ring Group, Auto Attendant menus, and Call Forward–No
Answer targets to an analog telephone.
An analog telephone connected to an FXS port can be used for Private Line
Automatic Ringdown (PLAR). When you enable the PLAR feature through the
WebUI, an analog telephone or device connected to an ATA FXS port will ring a
destination when it goes off hook.
For more information about configuring a PLAR destination, see “PLAR Setup”
in the Synapse Administrator’s Guide at
www.telephones.att.com/synapseguides.
A single fax machine to share your general telephone lines instead of using a
dedicated fax line
See “ATA Fax Line Configuration” on page 29. One of the two FXS station ports
can be configured to support a fax machine. The system administrator must
configure the Fax mode in the WebUI.
For more information about fax configuration and ATA configuration, see the
Synapse Administrator’s Guide at
www.telephones.att.com/synapseguides.
Overhead Paging Equipment (OHP)
See “Overhead Paging Overview” on page 20. The ATA provides three options to
connect OHP. The system administrator must configure the OHP in the WebUI.
Single-zone paging with OHP equipment connected to the ATA Aux Out jack
Single-zone paging with OHP equipment connected to one of the FXS station
ports
Multi-zone paging with OHP equipment connected to one of the FXS station
ports.

Loud Ringers
Loud Ringer devices must be connected to an FXS port assigned as Voice (default
setting). Loud Ringers can be used for alerting users of an incoming call via a
loud speaker and are treated within Synapse as a regular analog phone instead
of OHP equipment. This type of overhead alerting can only be done by including
the voice FXS port in a Ring Group.
A source for Music On Hold (MoH)
You can use the ATA to route MoH audio input to outside held, parked, or queued
calls. When external callers are placed on hold, parked, or enter a call queue,
they hear the audio source provided by the MoH input. The system administrator
must configure the MoH in the WebUI. For more information, see “Connecting a
Music on Hold Source” on page 49.
For MoH WebUI configuration, see “Hold Settings and Music on Hold
(Requires ATA)” in the Synapse Administrator’s Guide at
www.telephones.att.com/synapseguides.
Door phone
