Synapse Installation Guide 10 System Installation Overview
System Installation Overview
Install one SB67010 PSTN Gateway before installing any Desksets or the ATA (install the optional ATA last). The first Deskset is
assigned as Extension 200. Subsequent Desksets are assigned sequential Extension numbers. Figure 6 illustrates the minimum
components needed to make the system work (blue line = telephone; red lines = Ethernet).
Figure 6. Simplified System
The system uses a Local Area Network (LAN) for system communication. It uses Public Switched Telephone Network
(PSTN) phone lines for outside calls.
You can register one AT&T TL7600 Cordless Headset and/or one AT&T SB67040 Cordless Accessory Handset to any
Deskset, but only five Cordless devices can be registered to a system.
To integrate the Headset into the system, see “User Settings” in the Synapse User’s Guide at
www.telephones.att.com/synapseguides, rather than the manual that is packaged with the Headset.
