Synapse Installation Guide

Grounding

The SB67010 PSTN Gateway, the SB67060 T1 Gateway, and the SB67050 Analog Terminal Adapter must be connected to reliable
earth ground. The connection to earth ground must be verified by qualified personnel.
The SB67010 PSTN Gateway must be connected to reliable earth ground using the supplied ground wire connected to a terminal
on the back of the Gateway chassis.
The SB67060 T1 Gateway must be connected to reliable earth ground through a separate ground wire connected to a terminal
on the back of the Gateway chassis before connecting the T1 cable.
The SB67050 Analog Terminal Adapter is connected to earth ground through a properly grounded wall outlet. Additional
grounding may be necessary for the ATA if you need to improve immunity to Electrostatic Discharge (ESD) and to minimize the
possibility of electrical interference when using third-party audio equipment.
To provide additional grounding, the ATA can be connected to reliable earth ground through a separate ground wire connected
to a terminal on the back of the ATA chassis.
