System Installation Overview

Figure 1 illustrates how the Synapse system differs from conventional telephone systems

in that calls are not coordinated by a central controller. Instead, the system uses a

distributed control system over a new or existing LAN.

Figure 1. Sample System Network

A system must have at least one PSTN Gateway, one T1 Gateway, or one SIP Gateway.

There can be up to four PSTN Gateways, and a system can include a T1 Gateway, SIP

Gateway, and PSTN Gateways. Figure 2 illustrates the minimum components needed to

make the system work (blue line = telephone; red lines = Ethernet).

Figure 2. Simplified System (PSTN Gateway and SB67030/031 Deskset Shown)

The system uses a Local Area Network (LAN) for system communication. It uses

Public Switched Telephone Network (PSTN) connections for outside calls.
