Installation 13
Recommended Installation Sequence
1. Prepare your site for installation. See “Network Requirements” on page 15.
2. Install the Gateway(s). See “Gateway Installation” on page 33.
3. If you have only one Gateway, install the first Deskset. See “Deskset Installation” on
page 36. 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 16.
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 36.
7. Optional: Install the AT&T SB67050 Analog Terminal Adapter(s) (ATA). See “SB67050
ATA Installation” on page 43. If you install the ATA(s) 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(s) 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
an ATA. For more information, see:
 “Connecting Analog Telephones” on page 43
 “Connecting a Fax Machine” on page 44
 “Connecting an Overhead Paging System (OHP)” on page 45
 “Station Port (FXS) Door Phone Support” on page 25.
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.
