Power Considerations; Other Preparations - AT&T SB67010 PSTN Installation Manual

Synapse Installation Guide

Power Considerations

Ensure that there is an electrical outlet not controlled by a wall switch within 6 feet
(1.83 m) of each device location.
SB67020/025 Desksets and SB67031 Desksets are also compatible with Power over
Ethernet (PoE). To use PoE, your network needs a switch that provides PoE. Using PoE
simplifies your installation by eliminating the need to route separate power cords. It also
allows you to protect your system from power outages by connecting an Uninterruptible
Power Supply (UPS) to your PoE switch, Gateways, and ATA. For power requirement
specifications, see page 143.

Other Preparations

Before installing the Gateway and Desksets, the following preparations may need to be
taken:
All PSTN lines must be gathered into one access point situated no more than

9 feet (2.74 m) from the Gateway location. If you need to rewire your PSTN lines,
contact your telephone service provider and request the help of a qualified
technician.
You may need one or more network switches set up to ensure there are sufficient

ports available for other devices in the network (such as a DSL modem).
If you plan to use the emergency bypass feature on the PSTN Gateway, you will

need an analog phone.
An Ethernet Port must be available within 9 feet (2.74 m) of each Deskset

location. Each Deskset is capable of sharing an Ethernet port with a PC. If one
Ethernet port already exists at a workstation, another port is not necessary
unless you need a GigE Ethernet frame rate. Use a separate Ethernet connection
for the Deskset and the computer.
