Synapse Installation Guide

Overhead Paging Overview

You can set up either single or multi-zone external overhead paging (OHP), as shown in
Table 2, but only one OHP system can be connected to each ATA. You can also use a
loud ringer device, either on its own or with your existing OHP paging system, if
supported. For more information, see
Synapse supports most OHP systems that can connect to PBX Analog Station (FXS) ports
as well as those that support direct Audio Input detection, also known as VOX Detect.
This overview describes the differences between OHP systems and is intended to help
you determine how your system connects to the ATA. You should also refer to your OHP
system's product documentation for installation and configuration instructions or contact
your OHP equipment provider.
There are three possible OHP configurations:
Single-zone connected to the ATA AUX OUT jack

Single-zone connected to an ATA FXS port

Multi-zone connected to an ATA FXS port.

Table 2. Single- vs. Multi-Zone Overhead Paging Systems
Single-Zone Paging
Broadcasts to all overhead speakers at once.
Can be included in a Synapse Paging Zone.
Does not appear in the Deskset Paging Zones
menu unless you add Overhead Page to a
paging zone you create.
Requires no additional user input to initiate a
page.
For a connection through a FXS port, requires you
to set a delay determined by trial and error. This
delay, which starts after the user presses
gives the paging equipment time to prepare to
broadcast the message. It applies to every page,
even if the OHP is not the chosen paging zone.
Can be connected to an FXS port or the AUX Out
jack.
If your OHP is single-zone, you will have to decide whether it requires an FXS connection
or an AUX OUT connection. You can only connect a multi-zone OHP to an ATA FXS port,
i.e. a multi-zone OHP system cannot be connected to the AUX OUT port.
Equipment that can interface with the AUX OUT port can have no "intelligence" in its
audio output. It doesn't require any exchange of signals to be ready to broadcast.
Installation
"Loud Ringers" on page
Multi-Zone Paging
Broadcasts to speakers grouped into separate
zones.
Cannot be included in a Synapse Paging Zone
because the multi-zone OHP cannot be paged
together with Desksets.
Automatically appears in the Deskset Paging
Zones menu as Overhead Paging.
Requires using the Deskset dial pad to enter
digits to address the OHP paging zone.
There is no programmed delay as the paging
equipment provides feedback to the user when
, to start speaking.
Start
Must be connected to the FXS port.
