System Communication Overview

Synapse system devices are connected to a LAN via 10/100 Ethernet ports so they can
communicate with each other. Gateways also connect to the Public Switched Telephone
Network (PSTN) for outside calls. All devices require AC power.

Within-System Communication

When two or more Synapse devices are connected to the same subnet of a LAN, they
automatically recognize each other and synchronize with each other. You can view the
connection status of a Deskset by pressing MENU, then 4 on the Deskset dial pad to
display the Deskset Information screen. The second line of the screen shows the
synchronization status, as shown in Figure 8. The third line shows the Deskset IP address.
Gateways and the ATA display synchronization status and their IP addresses on their idle
screens as shown in Figure 10.
The system also assigns each device a local Internet protocol (IP) address (a link-local
address, which starts with 169.254), as shown in Figure 9. The local address is used for
communication among the Synapse devices. All local addresses are self-managed at each
device.

Communication with the PSTN

Gateways route calls between the PSTN and the internal IP-based Synapse system. Each
PSTN Gateway provides four PSTN jacks for plugging in up to four phone lines and the T1
Gateway provides one T1 jack that supports up to 23 voice channels. You can combine
up to four SB67010 PSTN Gateways and one T1 Gateway to support up to 39
simultaneous outside phone calls. One hundred Desksets can be connected to the
network subnet.
The first PSTN Gateway's lines are assigned as lines 1 through 4. If a second PSTN
Gateway is connected to the network, it is assigned lines 5 through 8.
