Single-Zone Paging - AT&T SB67010 PSTN Installation Manual

Synapse Installation Guide
Equipment that uses an FXS port must be able to go on and off hook, because the FXS
ports use telephone signals to exchange information. The OHP generally includes some
sort of controller or telephone interface, which often requires setting up, for example,
"PABX loop start trunk port access", or "RJ-11 for Tip and Ring connections".
Even if the OHP has no RJ-11 jack, it may still have a Tip/Ring interface, requiring
hard wiring. Whenever possible, try both the AUX OUT jack and an FXS port to
find the best configuration for your needs.
The OHP system may have settings that need to be adjusted to work with
Synapse. Refer to your OHP system's product documentation for installation and
configuration instructions.
Desksets and single-zone OHPs can be included in the same zone. In the case of
a single-zone OHP connected to the FXS port, this paging system and the
Desksets generate different paging tones. Note that users hear both tones at the
same time if the paging delay is set properly in the WebUI settings.
To install an OHP system, see
page 45.
For OHP WebUI configuration, see "Overhead Paging Overview (ATA Required)"
and "Creating, Editing and Deleting Paging Zones" in the Synapse Administrator's
Guide at

Single-Zone Paging

Single-zone paging means that all speakers connected to the OHP system are activated
together (that is, they are in the same zone).
Connecting to the AUX OUT jack
Use this configuration to connect single-zone paging equipment that uses a 3.5 mm
audio jack as input. For example, use this configuration if the OHP device is just an
amplified speaker. See
input levels are compatible with ATA level. See
page 142. Only single-zone paging is supported in this configuration.
Connecting to one of the FXS ports
Use this configuration to connect paging equipment that interfaces through a telephone
line. Typically, any OHP that connects to an FXS port has some intelligence to go off and
on hook or otherwise send a signal back to the pager. These are generally controllers or
telephone interfaces with controls and settings.
