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 43. 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. You can connect up to eight analog
telephones when the maximum of four ATAs are installed. 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 (one fax machine per system)
See “ATA Fax Line Configuration” on page 28. 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) (one OHP system per ATA)
See “Overhead Paging Overview” on page 22. 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.
