Synapse SB67030 and Accessories User's Guide
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 Local Area Network (LAN). Figure 3 illustrates a sample system
with outside telephone connections in blue and ethernet cables in red.
